The Connor-Davidson Resilience Scale (CD-RISC) measures various aspects of psychological resilience in patients with posttraumatic stress disorder (PTSD) and other psychiatric ailments. This study sought to assess the reliability and validity of the Korean version of the Connor-Davidson Resilience Scale (K-CD-RISC).
In total, 576 participants were enrolled (497 females and 79 males), including hospital nurses, university students, and firefighters. Subjects were evaluated using the K-CD-RISC, the Beck Depression Inventory (BDI), the Impact of Event Scale-Revised (IES-R), the Rosenberg Self-Esteem Scale (RSES), and the Perceived Stress Scale (PSS). Test-retest reliability and internal consistency were examined as a measure of reliability, and convergent validity and factor analysis were also performed to evaluate validity.
Cronbach's α coefficient and test-retest reliability were 0.93 and 0.93, respectively. The total score on the K-CD-RISC was positively correlated with the RSES (r=0.56, p<0.01). Conversely, BDI (r=-0.46, p<0.01), PSS (r=-0.32, p<0.01), and IES-R scores (r=-0.26, p<0.01) were negatively correlated with the K-CD-RISC. The K-CD-RISC showed a five-factor structure that explained 57.2% of the variance.
The K-CD-RISC showed good reliability and validity for measurement of resilience among Korean subjects.

Resilience may be an important component of prevention of neuropsychiatric disease. Resilience has proven to be quantifiable by scales such as the Connor-Davidson Resilience Scale (CD-RISC). Here, we introduce a 2-item version of this scale, the CD-RISC2. We hypothesize that this shortened version of the scale has internal consistency, test-retest reliability, convergent validity, and divergent validity as well as significant correlation with the full scale. Additionally, we hypothesize that the CD-RISC2 can be used to assess pharmacological modification of resilience. We test these hypotheses by utilizing data from treatment trials of post-traumatic stress disorder, major depression, and generalized anxiety disorder with setraline, mirtazapine, fluoxetine, paroxetine, venlafaxine XR, and kava as well as data from the general population, psychiatric outpatients, and family medicine clinic patients.

Resilience, the ability to adapt positively to adversity, may be an important factor in successful aging. However, the assessment and correlates of resilience in elderly individuals have not received adequate attention.
A total of 1,395 community-dwelling women over age 60 who were participants at the San Diego Clinical Center of the Women’s Health Initiative completed the Connor-Davidson Resilience Scale (CD-RISC), along with other scales pertinent to successful cognitive aging. Internal consistency and predictors of the CD-RISC were examined, as well as the consistency of its factor structure with published reports.
The mean age of the cohort was 73 (7.2) years and 14% were Hispanic, 76% were non-Hispanic white, and nearly all had completed a high school education (98%). The mean total score on the CD-RISC was 75.7 (SD=13.0). This scale showed high internal consistency (Cronbach’s alpha=0.92). Exploratory factor analysis yielded four factors (somewhat different from those previously reported among younger adults) that reflected items involving: 1) personal control and goal orientation, 2) adaptation and tolerance for negative affect, 3) leadership and trust in instincts, and 4) spiritual coping. The strongest predictors of CD-RISC scores in this study were higher emotional well-being, optimism, self-rated successful aging, social engagement, and fewer cognitive complaints.
Our study suggests that the CD-RISC is an internally consistent scale for assessing resilience among older women, and that greater resilience as assessed by the CD-RISC related positively to key components of successful aging.

The 10-item Connor-Davidson Resilience Scale (10-item CD-RISC) is an instrument for measuring resilience that has shown good psychometric properties in its original version in English. The aim of this study was to evaluate the validity and reliability of the Spanish version of the 10-item CD-RISC in young adults and to verify whether it is structured in a single dimension as in the original English version.
Cross-sectional observational study including 681 university students ranging in age from 18 to 30 years. The number of latent factors in the 10 items of the scale was analyzed by exploratory factor analysis. Confirmatory factor analysis was used to verify whether a single factor underlies the 10 items of the scale as in the original version in English. The convergent validity was analyzed by testing whether the mean of the scores of the mental component of SF-12 (MCS) and the quality of sleep as measured with the Pittsburgh Sleep Index (PSQI) were higher in subjects with better levels of resilience. The internal consistency of the 10-item CD-RISC was estimated using the Cronbach α test and test-retest reliability was estimated with the intraclass correlation coefficient.
The Cronbach α coefficient was 0.85 and the test-retest intraclass correlation coefficient was 0.71. The mean MCS score and the level of quality of sleep in both men and women were significantly worse in subjects with lower resilience scores.
The Spanish version of the 10-item CD-RISC showed good psychometric properties in young adults and thus can be used as a reliable and valid instrument for measuring resilience. Our study confirmed that a single factor underlies the resilience construct, as was the case of the original scale in English.

Posttraumatic stress disorder (PTSD) has previously been associated with increased risk for a variety of chronic medical conditions and it is often underdiagnosed in minority civilian populations. The current study examined the effects of resilience on the likelihood of having a diagnosis of PTSD in an inner-city sample of primary care patients (n = 767). We measured resilience with the Connor-Davidson Resilience Scale, trauma with the Childhood Trauma Questionnaire and Trauma Events Inventory, and assessed for PTSD with the modified PTSD symptom scale. Multiple logistic regression model with presence/absence of PTSD as the outcome yielded 3 significant factors: childhood abuse, nonchild abuse trauma, and resilience. One type of childhood abuse in moderate to severe range (OR, 2.01; p = .0001), 2 or more types of childhood abuse in moderate to severe range (OR, 4.00; p ≤ .0001), and 2 or more types of nonchildhood abuse trauma exposure (OR, 3.33; p ≤ .0001), were significantly associated with an increased likelihood of PTSD, while resilience was robustly and significantly associated with a decreased likelihood of PTSD (OR, 0.93; p ≤ .0001). By understanding the role of resilience in recovery from adverse experiences, improved treatment and interventional methods may be developed. Furthermore, these results suggest a role for assessing resilience in highly traumatized primary care populations as a way to better characterize risk for PTSD and direct screening/psychiatric referral efforts.

The objective of this study was to evaluate a resilience-enhancing program for youth (mean age = 13.32 years) from Beslan, North Ossetia, in the Russian Federation. The program, offered in the summer of 2006, combined recreation, sport, and psychosocial rehabilitation activities for 94 participants, 46 of who were taken hostage in the 2004 school tragedy and experienced those events first hand. Self-reported resilience, as measured by the CD-RISC, was compared within subjects at the study baseline and at two follow-up assessments: immediately after the program and 6 months later. We also compared changes in resilience levels across groups that differed in their traumatic experiences. The results indicate a significant intra-participant mean increase in resilience at both follow-up assessments, and greater self-reported improvements in resilience processes for participants who experienced more trauma events.
Influences of resilience on the presence and severity of depression following trauma exposure are largely unknown. Hence, we examined effects of resilience on depressive symptom severity in individuals with past childhood abuse and/or other trauma exposure.
In this cross-sectional study of 792 adults, resilience was measured with the Connor–Davidson Resilience Scale, depression with the Beck Depression Inventory (BDI), childhood abuse with the Childhood Trauma Questionnaire, and other traumas with the Trauma Events Inventory.
Multiple linear regression modeling with depression severity (BDI score) as the outcome yielded 4 factors: childhood abuse (β=2.5, p<0.0001), other trauma (β=3.5, p<0.0001), resilience (β=−0.5, p<0.0001), and other trauma×resilience interaction term (β=−0.1, p=0.0021), all of which were significantly associated with depression severity, even after adjusting for age, sex, race, education, employment, income, marital status, and family psychiatric history. Childhood abuse and trauma exposure contributed to depressive symptom severity while resilience mitigated it.
Resilience moderates depressive symptom severity in individuals exposed to childhood abuse or other traumas both as a main effect and an interaction with trauma exposure. Resilience may be amenable to external manipulation and could present a potential focus for treatments and interventions.

The present study examined the psychometric properties and diagnostic efficiency of the Davidson Trauma Scale (DTS), a self-report measure of posttraumatic stress disorder (PTSD) symptoms. Participants included 158 U.S. military veterans who have served since September 11, 2001 (post-9/11). Results support the DTS as a valid self-report measure of PTSD symptoms. The DTS demonstrated good internal consistency, concurrent validity, and convergent and divergent validity. Diagnostic efficiency was excellent when discriminating between veterans with PTSD and veterans with no Axis I diagnosis. However, although satisfactory by conventional standards, efficiency was substantially attenuated when discriminating between PTSD and other Axis I diagnoses. Thus, results illustrate that potency of the DTS as a diagnostic aid was highly dependent on the comparison group used for analyses. Results are discussed in terms of applications to clinical practice and research.

On February 27, 2010 (F-27), an earthquake and tsunami occurred having a significant impact on the mental health of the Chilean population, leading to an increase in cases of post-traumatic stress disorder (PTSD).
Within this context, validated for the first time in Chile was the Davidson Trauma Scale (DTS) using three samples (each one consisting of 200 participants), two of them random from the Chilean population.
Reliability analyses (i.e., α=0.933), concurrent validity (63% of the items are significantly correlated with the criteria variable “degree of damage to home”) and construct validity (i.e., CMIN = 3.754, RMSEA = 0.118, NFI = 0.808, CFI = 0.850 and PNFI = 0.689) indicate validity between regular and good for DTS. However, a new short version of the scale (DTS-SF) created using the items with heavier factor weights, presented better fits (CMIN = 2.170, RMSEA = 0.077, NFI = 0.935, CFI = 0.963, PNFI = 0.697).
Finally, the usefulness of DTS and DTS-SF is discussed, the latter being briefer, valid and having better psychometric characteristics.

To investigate whether higher resilience level predicts low levels of psychological distress in chronic SCI patients living in the community.
Thirty seven patients (mean age 41.5±10.9, male : female=28 : 9) with chronic spinal cord injury (duration 8.35±7.0 years) living in the community are included, who were hospitalized for annual checkups from November, 2010 to May, 2011. First, their spinal cord injury level, completeness and complications were evaluated. The patients completed questionnaires about their educational status, religion, employment status, marital status, medical and psychological history and also the following questionnaires: Hospital Anxiety and Depression Scale (HADS), Connor-Davidson Resilience Scale (CD-RISC), Alcohol Use Disorders Identification Test-alcohol consumption questions (AUDIT-C) and Health-related quality of life (EQ-5D). The patients were divided into two subgroups: patients with HADS ≥13 are classified as high psychological distress group and others as low psychological distress group. We compared the two groups to find statistically significant differences among the variables.
CD-RISC, EQ-5D and employment status are significantly different between two groups (p<0.05). In a forward stepwise regression, we found that EQ-5D had a greater contribution than CD-RISC to the psychological distress level.
In addition to health-related quality of life, resilience can be suggested as a possible predictor of psychological distress in chronic SCI patients.

The training to become a dentist can create psychological distress. The present study evaluates the structure of the ‘Perceived Stress Questionnaire’ (PSQ), its internal consistency model and interrelatedness with burnout, anxiety, depression and resilience among dental students.
The study employed a cross-sectional design. A sample of Spanish dental students (n = 314) completed the PSQ, the ‘Goldberg Anxiety and Depression Scale’ (GADS), ‘Connor-Davidson Resilience Scale’ (10-item CD-RISC) and ‘Maslach Burnout Inventory-Student Survey’ (MBI-SS). The structure was estimated using Parallel Analysis from polychoric correlations. Unweighted Least Squares was the method for factor extraction, using the Item Response Theory to evaluate the discriminative power of items. Internal consistency was assessed by squaring the correlation between the latent true variable and the observed variable. The relationships between the PSQ and the other constructs were analysed using Spearman’s coefficient.
The results showed a PSQ structure through two sub-factors (‘frustration’ and ‘tenseness’) with regard to one general factor (‘perceived stress’). Items that did not satisfy discriminative capacity were rejected. The model fit were acceptable (GFI = 0.98; RSMR = 0.06; AGFI = 0.98; NFI = 0.98; RFI = 0.98). All the factors showed adequate internal consistency as measured by the congeneric model (≥0.91). High and significant associations were observed between perceived stress and burnout, anxiety, depression and resilience.
The PSQ showed a hierarchical bi-factor structure among Spanish dental students. Using the questionnaire as a uni-dimensional scale may be useful in perceived stress level discrimination, while the sub-factors could help us to refine perceived stress analysis and improve therapeutic processes.
Physician distress is common and related to numerous factors involving physicians’ personal and professional lives. The present study was designed to assess the effect of a Stress Management and Resiliency Training (SMART) program for increasing resiliency and quality of life, and decreasing stress and anxiety among Department of Medicine (DOM) physicians at a tertiary care medical center.
Forty DOM physicians were randomized in a wait-list controlled clinical trial to either the SMART intervention or a wait-list control group for 8 weeks. The intervention involved a single 90 min one-on-one training in the SMART program. Primary outcome measures assessed at baseline and week 8 included the Connor Davidson Resilience Scale (CDRS), Perceived Stress Scale (PSS), Smith Anxiety Scale (SAS) and Linear Analog Self Assessment Scale (LASA).
Thirty-two physicians completed the study. A statistically significant improvement in resiliency, perceived stress, anxiety, and overall quality of life at 8 weeks was observed in the study arm compared to the wait-list control arm: CDRS: mean ± SD change from baseline +9.8 ± 9.6 vs. -0.8 ± 8.2, t(30) = 3.18, p = 0.003; PSS: -5.4 ± 8.1 vs. +2.2 ± 6.1, t(30) = -2.76, p = 0.010; SAS: -11.8 ± 12.3 vs.+ 2.9 ± 8.9, t(30) = -3.62, p = 0.001; and LASA: +0.4 ± 1.4 vs. -0.6 ± 1.0, t(30) = 2.29, p = 0.029.
A brief training to enhance resilience and decrease stress among physicians using the SMART program was feasible. Further, the intervention provided statistically significant improvement in resilience, stress, anxiety, and overall quality of life. In the future, larger clinical trials with longer follow-up and possibly wider dissemination of this intervention are warranted.

Background A need to provide treatment for people with anxiety and/or depression, and to provide preventive strategies for individuals who love them has been identified. In response, an innovative group therapy programme for people with anxiety and/or depression and a significant other of their choice was developed and implemented.
Methods Mixed methods were employed. Five ‘significant other’ groups were held between May 2005 and June 2006. All group participants were requested to complete the Depression Anxiety Stress Scale (DASS), World Health Organization Quality of Life Assessment (WHOQol) and Connor–Davidson Resilience Scale (CD-RISC), pre- and post-therapy, and three months after their last therapy session. In addition, participants who attended groups between July and September 2005 were invited to provide feedback about the group therapy in an individual semi-structured interview.
Results Pilot results indicate positive responses from clients, related to facilitation of knowledge and understanding and skills development. For people referred to the group significant improvements were found in the DASS scores, resilience, psychological health and living environment.
Limitations Due to the small sample size, and lack of follow-up data and control group, the findings need to be considered with caution and indicate the necessity to collect further data to provide conclusive findings.
Conclusions Overall, the outcome of the ‘significant other’ pilot programme was useful, in that it facilitated a number of positive outcomes for participants. Areas for further research have been identified including strategies to improve social relationships, the de-identification with the sick/supporter role, and testing this model with diverse populations and clinical groups.

Resilience is proposed as a significant component of successful aging. Young adult carriers of the Serotonin Transporter Polymorphism (5HTTLPR) short(s) allele appear to have reduced resilience to stress. We examined if presence of the short allele was associated with poorer emotional resilience in older adults.
In a cross-sectional study of 99 healthy, community-dwelling, older adults we determined 5HTTLPR genotype status and administered the Connor-Davidson Resilience Scale and self-reported measures of successful aging, cognition and health.
There was no significant association between the 5HTTLPR s allele and resilience. S allele carriers had worse cognition and self-report ratings of successful aging.
These findings suggest that the impact of the 5HTTLPR s allele on stress-related outcomes may attenuate with older age. However, s allele status appears to be a biomarker of poorer self-rated successful aging, and cognitive performance in older adults.

Whether psychological resilience correlates with neurocognitive performance is largely unknown. Therefore, we assessed association between neurocognitive performance and resilience in individuals with a history of childhood abuse or trauma exposure.
In this cross-sectional study of 226 highly traumatized civilians, we assessed neurocognitive performance, history of childhood abuse and other trauma exposure, and current depressive and PTSD symptoms. Resilience was defined as having ≥ 1 trauma and no current depressive or PTSD symptoms; non-resilience as having ≥ 1 trauma and current moderate/severe depressive or PTSD symptoms.
The nonresilient group had a higher percentage of unemployment (p = 0.002) and previous suicide attempts (p <0.0001) than the resilient group. Both groups had comparable education and performance on verbal reasoning, nonverbal reasoning, and verbal memory. However, the resilient group performed better on nonverbal memory (p=0.016) with an effect size of 0.35. Additionally, more severe childhood abuse or other trauma exposure was significantly associated with non-resilience. Better nonverbal memory was significantly associated with resilience even after adjusting for severity of childhood abuse, other trauma exposure, sex, and race using multiple logistic regression (adjusted OR=1.2; p=0.017).
We examined resilience as absence of psychopathology despite trauma exposure in a highly traumatized, low socioeconomic, urban population. Resilience was significantly associated with better nonverbal memory, a measure of ability to code, store, and visually recognize concrete and abstract pictorial stimuli. Nonverbal memory may be a proxy for emotional learning, which is often dysregulated in stress-related psychopathology, and may contribute to our understanding of resilience.

Although the prevalence of perinatal depression (depression occurring during pregnancy and postpartum) is 10%, little is known about psychiatric comorbidity in these women. We examined the prevalence of comorbid eating disorders (ED) and trauma history in women with perinatal depression.
A research questionnaire was administered to 158 consecutive patients seen in a perinatal psychiatry clinic during pregnancy (n=99) or postpartum (n=59). Measures included Structured Clinical Interview for DSM (SCID) IV-based questions for lifetime eating psychopathology and assessments of comorbid psychiatric illness including the State/Trait Anxiety Inventory (STAI), Patient Health Questionnaire (PHQ-9), Edinburgh Postnatal Depression Scale (EPDS), and Trauma Inventory.
In this cohort, 37.1% reported a putative lifetime ED history; 10.1% reported anorexia nervosa (AN), 10.1% reported bulimia nervosa (BN), 10.1% reported ED not otherwise specified-purging subtype (EDNOS-P), and 7.0% reported binge eating disorder (BED). Women with BN reported more severe depression (EPDS score, 19.1, standard deviation [SD 4.3], p=0.02; PHQ-severity 14.5, SD 7.4, p=0.02) than the referent group of women with perinatal depression and no ED history (EPDS 13.3, SD=6.1; PHQ 9.0, SD=6.2). Women with AN were more likely to report sexual trauma history than the referent group (62.5% vs. 29.3%, p<0.05), and those with BN were more likely report physical (50.0%, p<0.05) and sexual (66.7%, p<0.05) trauma histories.
ED histories were present in over one third of admissions to a perinatal psychiatry clinic. Women with BN reported more severe depression and histories of physical and sexual trauma. Screening for histories of eating psychopathology is important in women with perinatal depression.
Previous findings suggest a relation between trauma exposure and risk for schizotypal personality disorder (SPD). However, the reasons for this relationship are not well understood. Some research suggests that exposure to trauma, particularly early trauma and child abuse, as well as PTSD may play a role.
We examined subjects (N=541) recruited from the primary care clinics of an urban public hospital as part of an NIMH-funded study of trauma related risk and resilience. We evaluated childhood abuse with the Childhood Trauma Questionnaire (CTQ) and the Early Trauma Inventory (ETI) and SPD with the Schedule for Nonadaptive and Adaptive Personality (SNAP). We assessed for lifetime PTSD using the Clinician-Administered PTSD Scale (CAPS).
We found that of the three forms of abuse analyzed (emotional, physical, and sexual), only emotional abuse significantly predicted SPD (p<.001, R=0.28) when all three abuse types were simultaneously entered into a regression model. Lifetime PTSD symptoms also significantly predicted SPD (p<.001, R=0.26). PTSD was specifically predictive of four of the eight SPD symptoms (p≤.001): excessive social anxiety, a lack of close friends or confidants, unusual perceptual experiences, and eccentric behavior or appearance. Using a Sobel test, we also found a partial mediation effect of PTSD on the relation between emotional abuse and SPD (z=3.45, p<.001).
These findings point to the important influence of emotional abuse on SPD and suggest that PTSD symptoms may provide a link between damaging childhood experiences and SPD symptoms in traumatized adults.

The evaluation of interventions and policies designed to promote resilience, and research to understand the determinants and associations, require reliable and valid measures to ensure data quality. This paper systematically reviews the psychometric rigour of resilience measurement scales developed for use in general and clinical populations.
Eight electronic abstract databases and the internet were searched and reference lists of all identified papers were hand searched. The focus was to identify peer reviewed journal articles where resilience was a key focus and/or is assessed. Two authors independently extracted data and performed a quality assessment of the scale psychometric properties.
Nineteen resilience measures were reviewed; four of these were refinements of the original measure. All the measures had some missing information regarding the psychometric properties. Overall, the Connor-Davidson Resilience Scale, the Resilience Scale for Adults and the Brief Resilience Scale received the best psychometric ratings. The conceptual and theoretical adequacy of a number of the scales was questionable.
We found no current 'gold standard' amongst 15 measures of resilience. A number of the scales are in the early stages of development, and all require further validation work. Given increasing interest in resilience from major international funders, key policy makers and practice, researchers are urged to report relevant validation statistics when using the measures.
ICU nurses are repeatedly exposed to work related stresses resulting in the development of psychological disorders including posttraumatic stress disorder and burnout syndrome. Resilience is a learnable multidimensional characteristic enabling one to thrive in the face of adversity. In a national survey, we sought to determine whether resilience was associated with healthier psychological profiles in intensive care unit nurses.
Surveys were mailed to 3500 randomly selected ICU nurses across the United States and included: demographic questions, the Posttraumatic Diagnostic Scale, Hospital Anxiety and Depression Scale, Maslach Burnout Inventory and the Connor-Davidson Resilience Scale.
Measurements and Main Results
Overall, 1239 of the mailed surveys were returned for a response rate of 35%, and complete data was available on a total of 744 nurses. Twenty-two percent of the intensive care unit nurses were categorized as being highly resilient. The presence of high resilience in these nurses was significantly associated with a lower prevalence of posttraumatic stress disorder, symptoms of anxiety or depression, and burnout syndrome (<0.001 for all comparisons). In independent multivariable analyses adjusting for five potential confounding variables, the presence of resilience was independently associated with a lower prevalence of posttraumatic stress disorder (p < 0.001), and a lower prevalence of burnout syndrome (p < 0.001).
The presence of psychological resilience was independently associated with a lower prevalence of posttraumatic stress disorder and burnout syndrome in intensive care unit nurses. Future research is needed to better understand coping mechanisms employed by highly resilient nurses and how they maintain a healthier psychological profile.

No resilience scale has been validated in Spanish patients with fibromyalgia. The aim of this study was to evaluate the validity and reliability of the 10-item CD-RISC in a sample of Spanish patients with fibromyalgia.
Design: Observational prospective multicenter study. Sample: Patients with diagnoses of fibromyalgia recruited from primary care settings (N = 208). Instruments: In addition to sociodemographic data, the following questionnaires were administered: Pain Visual Analogue Scale (PVAS), the 10-item Connor-Davidson Resilience scale (10-item CD-RISC), the Fibromyalgia Impact Questionnaire (FIQ), the Hospital Anxiety and Depression Scale (HADS), the Pain Catastrophizing Scale (PCS), the Chronic Pain Acceptance Questionnaire (CPAQ), and the Mindful Attention Awareness Scale (MAAS).
Regarding construct validity, the factor solution in the Principal Component Analysis (PCA) was considered adequate, so the KMO test had a value of 0.91, and the Barlett’s test of sphericity was significant (χ2 = 852.8; gl = 45; p < 0.001). Only one factor showed an eigenvalue greater than 1, and it explained 50.4% of the variance. PCA and Confirmatory Factor Analysis (CFA) results did not show significant differences between groups. The 10-item CD-RISC scale demonstrated good internal consistency (Cronbach’s alpha = 0.88) and test-retest reliability (r = 0.89 for a six-week interval). The 10-item CD-RISC score was significantly correlated with all of the other psychometric instruments in the expected direction, except for the PVAS (−0.115; p = 0.113).
Our study confirms that the Spanish version of the 10-item CD-RISC shows, in patients with fibromyalgia, acceptable psychometric properties, with a high level of reliability and validity.

Although some previous studies have suggested that posttraumatic growth (PTG) is comprised of several factors with different properties, few have examined both the association between PTG and posttraumatic stress disorder (PTSD) and between PTG and resilience, focusing on each of the factors of PTG. This study aimed to examine the hypothesis that some factors of PTG, such as personal strength, relate to resilience, whereas other factors, such as appreciation of life, relate to PTSD symptoms among Japanese motor vehicle accident (MVA) survivors.
This cross-sectional study was performed with 118 MVA survivors at 18 months post MVA. Data analyzed included self-reporting questionnaire scores on the Posttraumatic Growth Inventory (PTGI), the Impact of Event Scale- Revised (IES-R), and the Sense of Coherence (SOC) scale, which is one of the most widely used scales for measuring resilience. Correlations between scores on the PTGI and IES-R, the PTGI and SOC scale, and the IES-R and SOC scale were established by calculating Spearman's correlation coefficients.
PTGI was positively correlated with both SOC and PTSD symptoms, in spite of an inverse relationship between SOC and PTSD symptoms. Relating to others, new possibilities, and personal strength on the PTGI were correlated positively with SOC, and spiritual change and appreciation of life on the PTGI were positively correlated with PTSD symptoms.
Some factors of PTG were positively correlated with resilience, which can be regarded as an outcome of coping success, whereas other factors of PTG were positively correlated with PTSD symptoms, which can be regarded as signifying coping effort in the face of enduring distress. These findings contribute to our understanding of the psychological change experienced by MVA survivors, and to raising clinicians' awareness of the possibility that PTG represents both coping effort coexisting with distress and outcome of coping success.
Research is needed that prospectively characterizes the intergenerational pattern of effects of childhood maltreatment and lifetime posttraumatic stress disorder (PTSD) on women’s mental health in pregnancy and on postpartum mental health and bonding outcomes. This prospective study included 566 nulliparous women in 3 cohorts: PTSD-positive, trauma-exposed resilient, and non-exposed to trauma.
Standardized telephone interviews with women who were less than 28 gestational weeks ascertained trauma history, PTSD diagnosis, and depression diagnosis. A six-week postpartum interview reassessed interim trauma, labor experience, PTSD, depression, and bonding outcomes.
Regression modeling indicates posttraumatic stress in pregnancy, alone, or comorbid with depression, is associated with postpartum depression (R2=.204, P<.001). Postpartum depression alone, or comorbid with posttraumatic stress, was associated with impaired bonding (R2=.195, P<.001). In both models, higher quality of life ratings in pregnancy were associated with better outcomes, while reported dissociation in labor was a risk for worse outcomes. The effect of a history of childhood maltreatment on both postpartum mental health and bonding outcomes was mediated by pre-existing mental health status.
Pregnancy represents an opportune time to interrupt the pattern of intergenerational transmission of abuse and psychiatric vulnerability. Further dyadic research is warranted beyond six weeks postpartum. Trauma-informed interventions for women who enter care with abuse-related PTSD or depression should be developed and tested.

Background. Data regarding depression and resilience among adolescents is still lacking. Objective. To assess depressive symptoms and resilience among pregnant adolescents. Method. Depressive symptoms and resilience were assessed using two validated inventories, the 10-item Center for Epidemiologic Studies Short Depression Scale (CESD-10) and the 14-item Wagnild and Young Resilience Scale (RS), respectively. A case-control approach was used to compare differences between adolescents and adults. Results. A total of 302 pregnant women were enrolled in the study, 151 assigned to each group. Overall, 56.6% of gravids presented total CESD-10 scores 10 or more indicating depressed mood. Despite this, total CESD-10 scores and depressed mood rate did not differ among studied groups. Adolescents did however display lower resilience reflected by lower total RS scores and a higher rate of scores below the calculated median (P < .05). Logistic regression analysis could not establish any risk factor for depressed mood among studied subjects; however, having an adolescent partner (OR, 2.0 CI 95% 1.06–4.0, P = .03) and a preterm delivery (OR, 3.0 CI 95% 1.43–6.55, P = .004) related to a higher risk for lower resilience. Conclusion. In light of the findings of the present study, programs oriented at giving adolescents support before, during, and after pregnancy should be encouraged.
Resilience is the ability to adapt successfully in the face of stress and adversity. Stressful life events, trauma, and chronic adversity can have a substantial impact on brain function and structure, and can result in the development of posttraumatic stress disorder (PTSD), depression and other psychiatric disorders. However, most individuals do not develop such illnesses after experiencing stressful life events, and are thus thought to be resilient. Resilience as successful adaptation relies on effective responses to environmental challenges and ultimate resistance to the deleterious effects of stress, therefore a greater understanding of the factors that promote such effects is of great relevance. This review focuses on recent findings regarding genetic, epigenetic, developmental, psychosocial, and neurochemical factors that are considered essential contributors to the development of resilience. Neural circuits and pathways involved in mediating resilience are also discussed. The growing understanding of resilience factors will hopefully lead to the development of new pharmacological and psychological interventions for enhancing resilience and mitigating the untoward consequences.

Background. Few disaster studies have specifically examined personality and resilience in association with disaster exposure, posttraumatic stress disorder (PTSD), and major depression. Methods. 151 directly-exposed survivors of the Oklahoma City bombing randomly selected from a bombing survivor registry completed PTSD, major depression, and personality assessments using the Diagnostic Interview Schedule for DSM-IV and the Temperament and Character Inventory, respectively. Results. The most prevalent postdisaster psychiatric disorder was bombing-related PTSD (32%); major depression was second in prevalence (21%). Bombing-related PTSD was associated with the combination of low self-directedness and low cooperativeness and also with high self-transcendence and high harm avoidance in most configurations. Postdisaster major depression was significantly more prevalent among those with (56%) than without (5%) bombing-related PTSD (P < .001)
and those with (72%) than without (14%) predisaster major depression (P < .001). Incident major depression was not associated with the combination of low self-directedness and low cooperativeness. Conclusions. Personality features can distinguish resilience to a specific life-threatening stressor from general indicators of well-being. Unlike bombing-related PTSD, major depression was not a robust marker of low resilience. Development and validation of measures of resilience should utilize well-defined diagnoses whenever possible, rather than relying on nonspecific measures of psychological distress.
