1.  Assessing negative cognitive style: Development and validation of a Short-Form version of the Cognitive Style Questionnaire 
Highlights
► We developed a Short-Form version of the Cognitive Style Questionnaire (CSQ). ► The CSQ Short Form (CSQ-SF) demonstrated satisfactory internal reliability. ► Test–retest reliability was also satisfactory. ► Scores demonstrated predicted correlations with measures of depression and anxiety. ► The CSQ-SF may be a useful research tool in assessing vulnerability to depression.
The Cognitive Style Questionnaire (CSQ) is a frequently employed measure of negative cognitive style, associated with vulnerability to anxiety and depression. However, the CSQ’s length can limit its utility in research. We describe the development of a Short-Form version of the CSQ. After evaluation and modification of two pilot versions, the 8-item CSQ Short Form (CSQ-SF) was administered to a convenience sample of adults (N = 278). The CSQ-SF was found to have satisfactory internal reliability and test–retest reliability. It also exhibited construct validity by demonstrating predicted correlations with measures of depression and anxiety. Results suggest that the CSQ-SF is suitable for administration via the Internet.

2.  Construct and Criterion-Based Validity of Brief Pain Coping Scales in Persons with Chronic Knee Osteoarthritis Pain 
Pain medicine (Malden, Mass.)  2012;14(2):265-275.
Objectives
A recent trend in clinical practice is to adopt short screening and diagnostic self-report instruments for patients with chronic pain. Brief 2-item pain coping and beliefs measures have recently been developed and have potential to improve decision making in clinical practice. Our study examined the construct and criterion-based validity of the 2-item per scale version of the Coping Strategies Questionnaire (CSQ).
Design
We used data obtained on a community-based sample of 873 persons with chronic knee osteoarthritis pain from the Osteoarthritis Initiative, a large longitudinal cohort study. Persons were administered the two-item per scale version of the CSQ. The International Classification of Functioning framework was used to select a variety of criterion-based measures for comparison to the CSQ. Spearman correlations and hierarchical regression models were used to characterize construct validity and Receiver Operating Characteristic Curves, sensitivity and specificity were used to describe criterion-based validity.
Results
Construct validity of the CSQ scales were generally supported, with the Catastrophizing and Praying or Hoping scales demonstrating the strongest construct validity across criterion measures. Criterion-based validity for the CSQ scales varied depending on the criterion measure. The Catastrophizing and Praying or Hoping scales also had the strongest criterion-based validity with ROC curve areas as high as 0.71 (95%CI= 0.67, 0.75), p<0.001 for identifying persons with substantial physical function deficits.
Conclusions
The findings suggest that several of the 2-item CSQ scales demonstrate a modest level of construct validity along with fair criterion-based validity. The Catastrophizing and Praying or Hoping scales appear to hold the most promise for clinical applications and future longitudinal research.

3.  High and Low Cognitive Risk For Depression: Stability From Late Adolescence to Early Adulthood 
Cognitive therapy and research  2009;33(5):480-498.
Negative cognitive styles are an important cognitive vulnerability for depression, but stability of high cognitive risk, once developed, is unclear. The current study examined stability of cognitive vulnerability to depression in individuals at high and low cognitive risk (extreme scores on both the CSQ and DAS) over a 7-year period from late adolescence through early adulthood. Cognitive vulnerability showed high relative stability, as evidenced by the moderate to high correlation (rs = .62) between cognitive risk status at study onset and at final assessment 7 years later. Consistent with stability, subgroups were identified using growth mixture modeling, and most cognitively high-risk (62.22% for CSQ, 68.89% for DAS) and low-risk (55.05% for CSQ, 57.96% for DAS) participants showed stable trajectories of cognitive vulnerability. Despite this overall pattern of stability, small mean group changes were found, and a minority of participants showed changing trajectories, consistent with regression toward the mean. Predictors of change and implications for risk for depression in high- and low-risk individuals are discussed.

4.  Cognitive Styles and Psychotic Experiences in a Community Sample 
PLoS ONE  2013;8(11):e80055.
Introduction
In clinical populations paranoid delusions are associated with making global, stable and external attributions for negative events. Paranoia is common in community samples but it is not known whether it is associated with a similar cognitive style. This study investigates the association between cognitive style and paranoia in a large community sample of young adults.
Methods
2694 young adults (mean age 17.8, SD 4.6) from the ALSPAC cohort provided data on psychotic experiences and cognitive style. Psychotic experiences were assessed using a semi-structured interview and cognitive style was assessed using the Cognitive Styles Questionnaire-Short Form (CSQ-SF) on the same occasion. Logistic regression was used to investigate associations between paranoia and CSQ-SF scores, both total and domain-related (global, stable, self, external). The role of concurrent self-reported depressive symptoms in the association was explored.
Results
Paranoia was associated with Total CSQ-SF scores (adjusted OR 1.69 95% CI 1.29, 2.22), as well as global (OR 1.56 95% CI 1.17, 2.08), stable (OR 1.56 95% CI 1.17, 2.08) and self (OR 1.37 95% CI 1.05, 1.79) domains, only Total score and global domain associations remained after additional adjustment for self-reported depression. There was no association between paranoia and external cognitive style (OR 1.10 95% CI 0.83, 1.47).
Conclusion
Paranoid ideation in a community sample is associated with a global rather than an external cognitive style. An external cognitive style may be a characteristic of more severe paranoid beliefs. Further work is required to determine the role of depression in the association between cognitive style and paranoia.

5.  The Value of Pain Coping Constructs in Subcategorising Back Pain Patients according to Risk of Poor Outcome 
BioMed Research International  2013;2013:898573.
Background. Subcategorising patients with chronic low back pain (CLBP) could improve patient outcomes and facilitate prioritisation of treatment resources. Objective. This study aimed to develop a subcategorising method for individuals with CLBP using the Coping Strategies Questionnaire 24 (CSQ24) and to investigate the methods potential validity. Methods. 196 patients were recruited from a physiotherapy outpatients department. All participants completed a battery of questionnaires before and after treatment including the CSQ24 and a measure of pain, disability, and mood. At discharge participants also completed a global subjective outcomes scale consisting of a 6-point Likert scale. All participants received usual physiotherapy. Results. Cut-off values for the CSQ24 were calculated using triangulation of the findings from three different statistical methods. Cut-off values were identified for the Catastrophising and Cognitive Coping subscales of the CSQ24. Participants were categorised into low, medium, and high risk of a poor outcome. The cut-off values for these were ≥21 on Cognitive Coping and ≤9 on Catastrophising for low risk and ≤15 on Cognitive Coping for high risk, with all other patients being classified as being at moderate risk. Conclusion. Further validation is required before this approach can be recommended for clinical practice.

6.  The Depressive Attributions Questionnaire (DAQ): Development of a Short Self-Report Measure of Depressogenic Attributions 
A depressogenic attributional style, i.e., internal, stable and global causal interpretations of negative events, is a stable vulnerability factor for depression. Current measures of pessimistic attributional style can be time-consuming to complete, and some are designed for specific use with student populations. We developed and validated a new short questionnaire suitable for the measurement of depressogenic attributions in clinical settings, the Depressive Attributions Questionnaire (DAQ). The 16-item DAQ, and measures of depression and related cognitive concepts were completed by three samples of depressed patients and matched controls, or depressed and non-depressed participants who had been exposed to a recent uncontrollable stressful life event (total N = 375). The DAQ had high (i) internal reliability, (ii) test-retest reliability, (iii) convergent, discriminant and construct validity. It predicted a diagnosis of major depression at 6 months after an uncontrollable stressor, over and above what could be predicted from initial depression severity. Depressed patients rated the scale as acceptable. The DAQ may be a useful short measure of depressogenic attributions, which is easy to administer, and predicts concurrent and future depression. It has possible applications as a screening measure for risk of depression, or as a treatment process measure.

7.  Responsiveness of five condition-specific and generic outcome assessment instruments for chronic pain 
Background
Changes of health and quality-of-life in chronic conditions are mostly small and require specific and sensitive instruments. The aim of this study was to determine and compare responsiveness, i.e. the sensitivity to change of five outcome instruments for effect measurement in chronic pain.
Methods
In a prospective cohort study, 273 chronic pain patients were assessed on the Numeric Rating Scale (NRS) for pain, the Short Form 36 (SF-36), the Multidimensional Pain Inventory (MPI), the Hospital Anxiety and Depression Scale (HADS), and the Coping Strategies Questionnaire (CSQ). Responsiveness was quantified by effect size (ES) and standardized response mean (SRM) before and after a four week in-patient interdisciplinary pain program and compared by the modified Jacknife test.
Results
The MPI measured pain more responsively than the SF-36 (ES: 0.85 vs 0.72, p = 0.053; SRM: 0.72 vs 0.60, p = 0.027) and the pain NRS (ES: 0.85 vs 0.62, p < 0.001; SRM: 0.72 vs 0.57, p = 0.001). Similar results were found for the dimensions of role and social interference with pain. Comparison in function was limited due to divergent constructs. The responsiveness of the MPI and the SF-36 was equal for affective health but both were better than the HADS (e.g. MPI vs HADS depression: ES: 0.61 vs 0.43, p = 0.001; SF-36 vs HADS depression: ES: 0.54 vs 0.43, p = 0.004). In the "ability to control pain" coping dimension, the MPI was more responsive than the CSQ (ES: 0.46 vs 0.30, p = 0.011).
Conclusion
The MPI was most responsive in all comparable domains followed by the SF-36. The pain-specific MPI and the generic SF-36 can be recommended for comprehensive and specific bio-psycho-social effect measurement of health and quality-of-life in chronic pain.

8.  Measuring patient satisfaction: a test of construct validity. 
Quality in Health Care  1992;1(2):104-109.
OBJECTIVE--To establish the validity of two patient satisfaction questionnaires (surgery satisfaction questionnaire (SSQ) and consultation satisfaction questionnaire (CSQ)) developed for use in general practice. DESIGN--Prospective study of performance of SSQ and CSQ in patients selected for their predicted levels of satisfaction. SETTING--Avon Family Health Services Authority (FHSA); general practices in Bristol (practice A) and in Cheltenham (practice B). PATIENTS--400 patients selected by Avon FHSA who had changed practices but not their home address and whose original practice had not changed its services (group 1); 869 randomly selected patients (221 from practice A, 648 from practice B) (group 2). MAIN MEASURES--Median difference in satisfaction scores for each questionnaire between groups 1 and 2 and between subgroups of group 2 patients according to assessed level in continuity of care (< 50%, > or = 50%) in the past 12 consultations. RESULTS--272 (68.0%) patients in group 1 completed the SSQ and CSQ. 711 (81.2%) patients in group 2 (178/221 (80.5%) in practice A, 533/648(82.3%) in practice B) completed the SSQ and 374(88/106(83.0%), 286/335(85.4%)) completed the CSQ. Both questionnaires classified patients in groups 1 and 2 according to the construct of satisfaction; thus the difference in median scores for every component of satisfaction in each questionnaire was significant and occurred in the direction predicted by the construct. Each questionnaire also discriminated between patients grouped according to their assessed level of continuity of care. CONCLUSION--SSQ and CSQ are valid measures of satisfaction for these types of patients. IMPLICATIONS--Valid measures of patient satisfaction can be developed; untested instruments should no longer be used.

9.  Reliability tests and validation tests of the client satisfaction questionnaire (CSQ-8) as an index of satisfaction with childbirth-related care among Filipino women 
Background
Satisfaction is an important indicator of the quality of care during childbirth. Previous research found that a good environment at a health facility can increase the number of deliveries at that facility. In contrast, an unsatisfying childbirth experience could cause postpartum mental disorder. Therefore it is important to measure mothers’ satisfaction with their childbirth experiences. We tested whether the eight-item Client Satisfaction Questionnaire (CSQ-8) provided useful information about satisfaction with childbirth-related care. The government of the Philippines promotes childbirth at health facilities, so we tested the CSQ-8 in the Philippine cities of Ormoc and Palo.
Methods
This was a cross-sectional study. We targeted multigravid mothers whose last baby had been delivered at a hospital (without complications) and whose 2nd-to-last baby had been delivered at a hospital or at home (without complications). We developed versions of the CSQ-8 in Cebuano and Waray, which are two of the six major Filipino languages. Reliability tests and validation tests were done with data from 100 Cebuano-speaking mothers and 106 Waray-speaking mothers.
Results
Both the Cebuano and Waray versions of the CSQ-8 had high coefficients of internal-consistency reliability (greater than 0.80). Both versions were also unidimensional, which is generally consistent with the English CSQ-8 in a mental-health setting. As hypothesized, the scores for data regarding the second-to-last delivery were higher for mothers who had both their second-to-last and their last delivery in a hospital, than for mothers who had their second-to-last delivery at home and their last delivery in a hospital (Cebuano: p < 0.001, rho = 0.51, Waray: p < 0.001, rho = 0.55).
Conclusions
Scores on the CSQ-8 can be used as indices of general satisfaction with childbirth-related services in clinical settings. This study also exemplifies a convenient method for developing versions of the CSQ-8 in more than one language. These versions of the CSQ-8 can now be used to assess mothers’ satisfaction, so that mothers’ opinions can be taken into account in efforts to improve childbirth-related services, which could increase the proportion of deliveries in medical facilities and thus reduce maternal mortality.

10.  Differences in pain, function and coping in Multidimensional Pain Inventory subgroups of chronic back pain: a one-group pretest-posttest study 
Background
Patients with non-specific back pain are not a homogeneous group but heterogeneous with regard to their bio-psycho-social impairments. This study examined a sample of 173 highly disabled patients with chronic back pain to find out how the three subgroups based on the Multidimensional Pain Inventory (MPI) differed in their response to an inpatient pain management program.
Methods
Subgroup classification was conducted by cluster analysis using MPI subscale scores at entry into the program. At program entry and at discharge after four weeks, participants completed the MPI, the MOS Short Form-36 (SF-36), the Hospital Anxiety and Depression Scale (HADS), and the Coping Strategies Questionnaire (CSQ). Pairwise analyses of the score changes of the mentioned outcomes of the three MPI subgroups were performed using the Mann-Whitney-U-test for significance.
Results
Cluster analysis identified three MPI subgroups in this highly disabled sample: a dysfunctional, interpersonally distressed and an adaptive copers subgroup. The dysfunctional subgroup (29% of the sample) showed the highest level of depression in SF-36 mental health (33.4 ± 13.9), the interpersonally distressed subgroup (35% of the sample) a modest level of depression (46.8 ± 20.4), and the adaptive copers subgroup (32% of the sample) the lowest level of depression (57.8 ± 19.1). Significant differences in pain reduction and improvement of mental health and coping were observed across the three MPI subgroups, i.e. the effect sizes for MPI pain reduction were: 0.84 (0.44 - 1.24) for the dysfunctional subgroup, 1.22 (0.86 - 1.58) for the adaptive copers subgroup, and 0.53 (0.24 - 0.81) for the interpersonally distressed subgroup (p = 0.006 for pairwise comparison). Significant score changes between subgroups concerning activities and physical functioning could not be identified.
Conclusions
MPI subgroup classification showed significant differences in score changes for pain, mental health and coping. These findings underscore the importance of assessing individual differences to understand how patients adjust to chronic back pain.

11.  Chronic pain coping styles in patients with herniated lumbar discs and coexisting spondylotic changes treated surgically: Considering clinical pain characteristics, degenerative changes, disability, mood disturbances, and beliefs about pain control 
Background
Pain catastrophizing, appraisals of pain control, styles of coping, and social support have been suggested to affect functioning in patients with low back pain. We investigated the relation of chronic pain coping strategies to psychological variables and clinical data, in patients treated surgically due to lumbar disc herniation and coexisting spondylotic changes.
Material/Methods
The average age of study participants (n=90) was 43.47 years (SD 10.21). Patients completed the Polish versions of the Chronic Pain Coping Inventory-42 (PL-CPCI-42), Beck Depression Inventory (BDI-PL), Coping Strategies Questionnaire (CSQ-PL), Beliefs about Pain Control Questionnaire (BPCQ-PL), and Roland-Morris Disability Questionnaire (RMQ-PL).
Results
In the PL-CPCI-42 results, resting, guarding and coping self-statements were frequently used as coping strategies (3.96 SD 1.97; 3.72 SD 1.72; 3.47 SD 2.02, respectively). In the CSQ-PL domains, catastrophizing and praying/hoping were frequently used as coping strategies (3.62 SD 1.19). The mean score obtained from the BDI-PL was 11.86 SD 7.23, and 12.70 SD 5.49 from the RMDQ-PL. BPCQ-PL results indicate that the highest score was in the subscale measuring beliefs that powerful others can control pain (4.36 SD 0.97). Exercise correlated significantly with beliefs about internal control of pain (rs=0.22). We identified associations between radiating pain and guarding (p=0.038) and between sports recreation and guarding (p=0.013) and task persistence (p=0.041).
Conclusions
Back pain characteristics, depressive mood, disability, and beliefs about personal control of pain are related to chronic LBP coping styles. Most of the variables related to advancement of degenerative changes were not associated with coping efforts.

12.  Validation of English and Spanish-Language Versions of a Screening Questionnaire for Rheumatoid Arthritis in an Underserved Community 
The Journal of rheumatology  2008;35(8):1545-1549.
Objective
Questionnaires to screen for rheumatoid arthritis (RA) have been tested in groups that were primarily well educated and Caucasian. We sought to validate the RA questions of the Connective Tissue Disease Screening Questionnaire (CSQ) in ethnic minorities in an underserved community, and to test a Spanish-language version.
Methods
The Spanish-language version was developed by 2 native speakers. Consecutive English-speaking or Spanish-speaking patients in a community-based rheumatology practice completed the questionnaire. Diagnoses were confirmed by medical record review. Sensitivity and specificity of the questionnaire for a diagnosis of RA were computed for each language version, using 2 groups as controls: patients with noninflammatory conditions, and participants recruited from the community.
Results
The English-language version was tested in 53 patients with RA (79% ethnic minorities; mean education level 11.3 yrs), 85 rheumatology controls with noninflammatory conditions, and 82 community controls. Using 3 positive responses as indicating a positive screening test, the sensitivity of the questionnaire was 0.77, the specificity based on rheumatology controls was 0.45, and the specificity based on community controls was 0.94. The Spanish-language version was tested in 55 patients with RA (mean education level 7.8 yrs), 149 rheumatology controls, and 88 community controls. The sensitivity of the Spanish-language version was 0.87, with specificities of 0.60 and 0.97 using the rheumatology controls and community controls, respectively.
Conclusion
The sensitivity of the English-language version of the RA questions of the CSQ was lower in this study than in other cohorts, reflecting differences in the performance of the questions in different ethnic or socioeconomic groups. The Spanish-language version demonstrated good sensitivity, and both had excellent specificity when tested in community controls.

13.  Catastrophizing is related to pain ratings, but not nociceptive flexion reflex threshold 
Pain  2002;99(3):459-463.
Catastrophizing is reliably associated with increased reports of clinical and experimental pain. To test the hypothesis that catastrophizing may heighten pain experience by increasing nociceptive transmission through spinal gating mechanisms, the present study examined catastrophizing as a predictor of pain ratings and nociceptive flexion reflex (NFR) thresholds in 88 young adult men (n = 47) and women (n = 41). The NFR threshold was defined as the intensity of electrocutaneous sural nerve stimulation required to elicit a withdrawal response from the biceps femoris muscle of the ipsilateral leg. Participants completed an assessment of their NFR threshold and then provided pain ratings using both a numerical rating scale (NRS) and the short-form McGill pain questionnaire (SF-MPQ). Pain catastrophizing was assessed using the catastrophizing subscale of the coping strategies questionnaire (CSQ). Although catastrophizing was positively related to both NRS and SF-MPQ pain ratings, catastrophizing was not significantly related to NFR threshold. These findings suggest that differential modulation of spinal nociceptive input may not account for the relationship between catastrophizing and increased pain.

14.  The Shoulder Pain and Disability Index demonstrates factor, construct and longitudinal validity 
Background
The Shoulder Pain and Disability Index (SPADI) is a self-report measure developed to evaluate patients with shoulder pathology. While some validation has been conducted, broader analyses are indicated. This study determined aspects of cross-sectional and longitudinal validity of the SPADI.
Methods
Community volunteers (n = 129) who self-identified as having shoulder pain were enrolled. Patients were examined by a physical therapist using a standardized assessment process to insure that their pain was musculoskeletal in nature. This included examination of pain reported during active and passive shoulder motion as reported on a visual analogue pain scale. Patients completed the SPADI, the Coping Strategies Questionnaire (CSQ) and the Sickness Impact Profile (SIP) at a baseline assessment and again 3 and 6 months later. Factor analysis with varimax rotation was used to assess subscale structure. Expectations regarding convergent and divergent subscales of CSQ and SIP were determined a priori and analysed using Pearson correlations. Constructed hypotheses that patients with a specific diagnosis or on pain medication would demonstrate higher SPADI scores were tested. Correlations between the observed changes recorded across different instruments were used to assess longitudinal validity.
Results
The internal consistencies of the SPADI subscales were high (α > 0.92). Factor analysis with varimax rotation indicated that the majority of items fell into 2 factors that represent pain and disability. Two difficult functional items tended to align with pain items. Higher pain and disability was correlated to passive or negative coping strategies, i.e., praying/hoping, catastrophizing on the CSQ. The correlations between subscales of the SPADI and SIP were low with divergent subscales and low to moderate with convergent subscales. Correlations, r > 0.60, were observed between the SPADI and pain reported on a VAS pain scale during active and passive movement. The two constructed validity hypotheses (on diagnosis and use of pain medications) were both supported (p < 0.01). The SPADI demonstrated significant changes over time, but these were poorly correlated to the SIP or CSQ suggesting that these scales measure different parameters.
Conclusion
The SPADI is a valid measure to assess pain and disability in community-based patients reporting shoulder pain due to musculoskeletal pathology.

15.  Stability of Cognitive Vulnerabilities to Depression: A Short-Term Prospective Multiwave Study 
Journal of abnormal psychology  2008;117(2):324-333.
The stability of 3 cognitive vulnerabilities—a negative cognitive style, dysfunctional attitudes, and rumination—as well as depressive symptoms as a benchmark were examined to investigate whether cognitive vulnerabilities are stable, enduring risks for depression. A sample of adolescents (6th–10th graders) completed measures of these 3 cognitive vulnerabilities and depressive symptoms every 5 weeks for 4 waves of data across 5 months. Mean-level and differential stability were examined for the sample overall and by age subgroups. A negative cognitive style exhibited mean-level stability, whereas rumination and dysfunctional attitudes showed some mean-level change. Absolute magnitudes of test–retest reliabilities were strong for depressive symptoms (mean r = .70), moderately high for a negative cognitive style (mean r = .52), and more modest for rumination (mean r = .28) and dysfunctional attitudes (mean r = .26). Structural equation modeling showed that primarily enduring processes, but not contextual forces, contributed to the patterning of these test–retest reliabilities over time for a negative cognitive style and dysfunctional attitudes, whereas both enduring and contextual dynamics appeared to underlie the stability for rumination. Theoretical and clinical implications of these findings are discussed.

16.  Development of the Well-being questionnaire short-form in Japanese: the W-BQ12 
Background
The Well-being Questionnaire (W-BQ) was designed to measure psychological well-being in people with diabetes. This study aimed to develop a Japanese version and a short form of the W-BQ.
Methods
A linguistic validation process produced a preliminary Japanese version of the 22-item W-BQ, which was distributed to 550 patients. Factor structure, reliability (Cronbach's alpha) and aspects of validity (hypothesised group differences and correlations with other measures) were evaluated.
Results
Questionnaires were returned by 464 patients (84.4%). Preliminary factor analysis revealed that the Depression and Anxiety items were dispersed according to the positive or negative direction of the wording. A 12-item W-BQ (Japanese W-BQ12), consisting of three 4-item subscales (Negative Well-being, Energy and Positive Well-being), was constructed that balanced positively and negatively worded items. Cronbach's alpha was high (>0.85) for the 12-item questionnaire and consistently high (>0.82) across sex and treatment subgroups. Cronbach's alpha for subscale scores in the total sample ranged from 0.69 (Energy) to 0.80 (Positive Well-being). Expected subgroup differences indicated significantly poorer well-being in women compared with men and in insulin-treated patients compared with tablet/diet treated patients. Discriminant and convergent validity was supported by minimal correlations between W-BQ12 scores and HbA1c and low-to-moderate correlations with Diabetes Treatment Satisfaction Questionnaire (DTSQ) scores.
Conclusion
The W-BQ12 (Japanese) is a short, reliable and valid measure of psychological well-being that is suitable for use with people with diabetes. The items selected to produce the W-BQ12 (Japanese) have since produced psychometrically sound 12-item short-form measures in other translations for use in diabetes and in other chronic illnesses.

17.  An examination of the association between the 5-HTT promoter region polymorphism and depressogenic attributional styles in childhood 
Although a vast literature examining the role of attributional styles in depression has accumulated, the origins of such cognitions remain poorly understood. Investigators are increasingly interested in whether cognitive vulnerability to depression is linked to genetic variation. As a preliminary test of this hypothesis, we examined whether the serotonin transporter promoter polymorphism (5-HTTLPR) was associated with attributional styles in children. Thirty-eight children completed a self-report measure of attributional styles, the Child Attributional Style Questionnaire-Revised (CASQ-R). Children were also genotyped for the 5-HTTLPR polymorphism, including the single nucleotide polymorphism (SNP) rs25531 in the long allele of the 5-HTTLPR. The short alleles of the 5-HTTLPR and their putative functional equivalents were associated with increased levels of depressogenic attributions for negative events, as measured by the CASQ-R, lending support to the role of 5-HTTLPR polymorphisms in cognitive vulnerability to depression.

18.  McMaster-Toronto Arthritis Patient Preference Disability Questionnaire Sensitivity to Change in Low Back Pain: Influence of Shifts in Priorities 
PLoS ONE  2011;6(5):e20274.
Objective
To assess the sensitivity to change of the McMaster Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR) in chronic low back pain (CLBP) and shifts in patients' priorities of disabling activities over time.
Methods
A prospective longitudinal survey of 100 patients (38 males) with CLBP in a tertiary care teaching hospital. Evaluation at baseline and 6 months by the MACTAR, Quebec Back Pain Disability Questionnaire (QUEBEC), Hospital Anxiety and Depression scale (HAD), Fear-Avoidance Beliefs Questionnaire (FABQ), Coping Strategies Questionnaire (CSQ), and pain and handicap visual analogue scales (VASs). Patients' perceived improvement or worsening of condition was assessed at 6 months. Effect size (ES) and Standardized response mean (SRM) and effect size (ES) were used to evaluate sensitivity to change of the MACTAR.
Results
The MACTAR SRM and ES values (SRM = 0.25; ES = 0.37) were among the highest for the instruments evaluated. For patients considering their condition as improved, the SRM was 0.66 and the ES 1. The 3 disability domains, classified by the International Classification of Functioning, Disability and Health (ICF), most often cited as priorities at baseline remained the most cited at follow-up: mobility (40.9% of patients); community, social and civic life (22.7%); and domestic life (22.4%). At 6 months, 48 patients shifted their priorities, for a decrease in MACTAR SRM and ES values for patients considering their condition improved and an increase in these values for those considering their condition deteriorated.
Conclusions
Although the MACTAR has similar sensitivity to change as other outcome measures widely used in CLBP, shifts in patient priorities over time are common and influence scores and sensitivity to change.

19.  Responding to Anxiety with Rumination and Hopelessness: Mechanism of Anxiety-Depression Symptom Co-Occurrence? 
Cognitive therapy and research  2012;36(4):321-337.
The current research proposes that certain anxiety response styles (specifically, responding to anxiety symptoms with rumination or hopeless cognitions) may increase risk of depressive symptoms, contributing to anxiety-depression comorbidity. We delineate preliminary evidence for this model in three studies. In Study 1, controlling for anxiety response styles significantly reduced the association between anxiety and depressive symptoms in an undergraduate sample. In Study 2, these findings were replicated controlling for conceptually related variables, and anxiety interacted with anxiety response styles to predict greater depressive symptoms. In Study 3, anxiety response styles moderated the prospective association between anxiety and later depression in a generalized anxiety disorder sample. Results support a role for anxiety response styles in anxiety-depression co-occurrence, and show that hopeless/ruminative anxiety response styles can be measured with high reliability and convergent and divergent validity.

20.  Willingness to Participate in Cancer Screenings: Blacks vs Whites vs Puerto Rican Hispanics 
Background
In the United States, blacks and Hispanics have lower cancer screening rates than whites have. Studies on the screening behaviors of minorities are increasing, but few focus on the factors that contribute to this discrepancy. This study presents the self-reported willingness by blacks, Puerto Rican Hispanics, and non-Hispanic whites to participate in cancer screenings in differing cancer screening situations.
Methods
The Cancer Screening Questionnaire (CSQ), a 60-item questionnaire, was administered via random-digit-dial telephone interviews to adults in three cities: Baltimore, Maryland; New York, New York; and, San Juan, Puerto Rico.
Results
The 1,148 participants in the CSQ study sample consisted of 355 blacks, 311 Puerto Rican Hispanics, and 482 non-Hispanic whites. Response rates ranged from 45% to 58% by city. Multivariable logistic regression analyses revealed that blacks and Puerto Ricans were often more likely (OR 2.0-3.0) and never less likely than whites to self-report willingness to participate in cancer screenings regardless of who conducted the cancer screening, what one was asked to do in the cancer screening, or what type of cancer was involved (with the exception of skin cancer where blacks, compared with whites, had an OR of 0.5).
Conclusions
The findings from this study provide evidence that blacks and Hispanics self-report that they are either as willing or more willing than whites to participate in cancer screening programs.

21.  Validation of the Spanish versions of the long (26 items) and short (12 items) forms of the Self-Compassion Scale (SCS) 
Background
Self-compassion is a key psychological construct for assessing clinical outcomes in mindfulness-based interventions. The aim of this study was to validate the Spanish versions of the long (26 item) and short (12 item) forms of the Self-Compassion Scale (SCS).
Methods
The translated Spanish versions of both subscales were administered to two independent samples: Sample 1 was comprised of university students (n = 268) who were recruited to validate the long form, and Sample 2 was comprised of Aragon Health Service workers (n = 271) who were recruited to validate the short form. In addition to SCS, the Mindful Attention Awareness Scale (MAAS), the State-Trait Anxiety Inventory–Trait (STAI-T), the Beck Depression Inventory (BDI) and the Perceived Stress Questionnaire (PSQ) were administered. Construct validity, internal consistency, test-retest reliability and convergent validity were tested.
Results
The Confirmatory Factor Analysis (CFA) of the long and short forms of the SCS confirmed the original six-factor model in both scales, showing goodness of fit. Cronbach’s α for the 26 item SCS was 0.87 (95% CI = 0.85-0.90) and ranged between 0.72 and 0.79 for the 6 subscales. Cronbach’s α for the 12-item SCS was 0.85 (95% CI = 0.81-0.88) and ranged between 0.71 and 0.77 for the 6 subscales. The long (26-item) form of the SCS showed a test-retest coefficient of 0.92 (95% CI = 0.89–0.94). The Intraclass Correlation (ICC) for the 6 subscales ranged from 0.84 to 0.93. The short (12-item) form of the SCS showed a test-retest coefficient of 0.89 (95% CI: 0.87-0.93). The ICC for the 6 subscales ranged from 0.79 to 0.91. The long and short forms of the SCS exhibited a significant negative correlation with the BDI, the STAI and the PSQ, and a significant positive correlation with the MAAS. The correlation between the total score of the long and short SCS form was r = 0.92.
Conclusion
The Spanish versions of the long (26-item) and short (12-item) forms of the SCS are valid and reliable instruments for the evaluation of self-compassion among the general population. These results substantiate the use of this scale in research and clinical practice.

22.  Coping and health service utilisation in a UK study of paediatric sickle cell pain 
Archives of Disease in Childhood  2002;86(5):325-329.
Aims: To assess sickle cell pain and coping in children and to examine the relation between these factors and the utilisation of health services.
Methods: Cross sectional study involving 67 children with sickle cell disease attending three London hospitals. Interviews and questionnaires involved measures of pain, health service utilisation, and coping responses (measured with the Coping Strategies Questionnaire (CSQ), revised for children with sickle cell disease). Medical data on complications, haemoglobin (Hb) levels, and foetal haemoglobin (HbF) percentage were also collected.
Results: Pain accounted for about 24% of hospital service use, independent of age, sex, number of with sickle cell disease complications, and Hb levels. However, 42% of patients had not utilised hospital services in the past 12 months. Three higher order factors emerged from analysis of the CSQ (active coping, affective coping, passive adherence coping). Pain severity was predicted by passive adherence coping, while utilisation of hospital services was predicted by active coping.
Conclusions: Sickle cell disease in children involves severe recurrent pain leading to hospitalisation in some cases. Psychological coping patterns are relevant to both pain experience, and the use of acute hospital services. It is likely that children would benefit from community based interventions that incorporate both medical and psychological assessments.

23.  Fear of Pain, Pain Catastrophizing, and Acute Pain Perception: Relative Prediction and Timing of Assessment 
Pain-related fear and catastrophizing are important variables of consideration in an individual’s pain experience. Methodological limitations of previous studies limit strong conclusions regarding these relationships. In this follow-up study, we examined the relationships between fear of pain, pain catastrophizing, and experimental pain perception. One hundred healthy volunteers completed the Fear of Pain Questionnaire (FPQ-III), Pain Catastrophizing Scale (PCS), and Coping Strategies Questionnaire-Catastrophizing scale (CSQ-CAT) before undergoing the cold pressor test (CPT). The CSQ-CAT and PCS were completed again following the CPT, with participants instructed to complete these measures based on their experience during the procedure. Measures of pain threshold, tolerance, and intensity were collected and served as dependent variables in separate regression models. Sex, pain catastrophizing, and pain-related fear were included as predictor variables. Results of regression analyses indicated that after controlling for sex, pain-related fear was a consistently stronger predictor of pain in comparison to catastrophizing. These results were consistent when separate measures (CSQ-CAT vs. PCS) and time points (pre-task vs. “in-vivo”) of catastrophizing were used. These findings largely corroborate those from our previous study and are suggestive of the absolute and relative importance of pain-related fear in the experimental pain experience.
Perspective
Although pain-related fear has received less attention in the experimental literature than pain catastrophizing, results of the current study are consistent with clinical reports highlighting this variable as an important aspect of the experience of pain.

24.  Self-Reported Stomach Upset in Travellers on Cruise-Based and Land-Based Package Holidays 
PLoS ONE  2014;9(1):e83425.
Background
International travellers are at a risk of infectious diseases not seen in their home country. Stomach upsets are common in travellers, including on cruise ships. This study compares the incidence of stomach upsets on land- and cruise-based holidays.
Methods
A major British tour operator has administered a Customer Satisfaction Questionnaire (CSQ) to UK resident travellers aged 16 or more on return flights from their holiday abroad over many years. Data extracted from the CSQ was used to measure self-reported stomach upset in returning travellers.
Results
From summer 2000 through winter 2008, 6,863,092 questionnaires were completed; 6.6% were from cruise passengers. A higher percentage of land-based holiday-makers (7.2%) reported stomach upset in comparison to 4.8% of cruise passengers (RR = 1.5, p<0.0005). Reported stomach upset on cruises declined over the study period (7.1% in 2000 to 3.1% in 2008, p<0.0005). Over 25% of travellers on land-based holidays to Egypt and the Dominican Republic reported stomach upset. In comparison, the highest proportion of stomach upset in cruise ship travellers were reported following cruises departing from Egypt (14.8%) and Turkey (8.8%).
Conclusions
In this large study of self-reported illness both demographic and holiday choice factors were shown to play a part in determining the likelihood of developing stomach upset while abroad. There is a lower cumulative incidence and declining rates of stomach upset in cruise passengers which suggest that the cruise industry has adopted operations (e.g. hygiene standards) that have reduced illness over recent years.

25.  Cognitive Vulnerabilities and Depression versus Other Psychopathology Symptoms and Diagnoses in Early Adolescence 
Objective
We examined the concurrent associations between multiple cognitive vulnerabilities to depression featured in Hopelessness Theory, Beck’s Theory, and Response Styles Theory and depressive symptoms and diagnoses in a sample of early adolescents. We also examined the specificity of these cognitive vulnerabilities to depression versus anxiety and externalizing psychopathology, controlling for co-occurring symptoms and diagnoses.
Method
Male and female, Caucasian and African-American, 12–13 year old adolescents were assessed in a cross-sectional design. Cognitive vulnerabilities of hopelessness, inferential style, rumination, and self-referent information processing were assessed with self-reports and behavioral tasks. Symptoms and diagnoses of depressive, anxiety, and externalizing disorders were assessed with self-report questionnaires and diagnostic interviews.
Results
Hopelessness exhibited the greatest specificity to depressive symptoms and diagnoses, whereas negative inferential styles, rumination, and negative self-referent information processing were associated with both depressive and anxiety symptoms and diagnoses and, in some cases, with externalizing disorders.
Conclusions
Consistent with cognitive theories of depression, hopelessness, negative inferential styles, rumination, and negative self-referent information processing were associated with depressive symptoms and diagnoses. However, with the exception of hopelessness, most of the remaining cognitive vulnerabilities were not specific to depression. With further maturation of our sample, these cognitive vulnerabilities may become more specific to depression as cognitive styles further develop and consolidate, the rates of depression increase, and individuals’ presentations of psychopathology become more differentiated.
