To test the relationships between worry and perceptions of likelihood and severity (two indicators of risk perception) across eight common diseases, and to examine contributions of individual and disease variability in worry and risk perceptions.
Participants were 294 people recruited through the Multiplex Initiative, in which a genetic susceptibility test for 8 common diseases was offered to healthy adults. Participants completed a baseline telephone survey and Web-based surveys measuring the variables for this ancillary study, without a commitment to be tested.
Between- and within-subjects analyses yielded the following findings: 1) worry is more related to likelihood perceptions than to severity perceptions; 2) severity perceptions add significantly to explained worry variances above and beyond likelihood perceptions; 3) the likelihood × severity perception does not add to explained variance in worry above its components; 4) risk perceptions and worries form two identifiable clusters: cancer diseases and cardiovascular-metabolic diseases; 5) there are significant differences in risk perceptions and worry among diseases; 6) there are significant gender differences in risk perceptions and worry about common diseases; 7) variance in risk perception and worry is explained by a combination of between- and within-subjects variances, with the latter being more powerful.
Risk perception research should pay attention to severity perceptions, within-subjects variability and inter-disease differences should not be ignored, gender perspectives on illness perceptions should be acknowledged, and health psychologists must prepare for considering groups of illnesses in addition to single diseases.

The aim of the current study was to learn how people integrate attitudes about multiple health conditions to make a decision about genetic testing uptake.
This study recruited 294 healthy young adults from a parent research project, the Multiplex Initiative, conducted in a large health care system in Detroit, Michigan. All participants were offered a multiplex genetic test that assessed risk for 8 common health conditions (e.g., type 2 diabetes). Data were collected from a baseline survey, a web-based survey, and at the time of testing.
Averaging attitudes across diseases predicted test uptake but did not contribute beyond peak attitudes, the highest attitude toward testing for a single disease in the set. Peak attitudes were found sufficient to predict test uptake.
The effects of set size and mode of presentation could not be examined because these factors were constant in the multiplex test offered.
These findings support theories suggesting that people use representative evaluations in attitude formation. The implication of these findings for further developments in genetic testing is that the communication and impact of multiplex testing may need to be considered in the light of a bias toward peak attitudes.

Prostate cancer is one of the most common forms of cancer among American men, and worry about the disease has psychological, behavioral, and biological consequences. To better understand prostate cancer–specific worry, the authors tested a model of the interrelationships among family history of prostate cancer, perceived risk of and worry about prostate cancer, and perceived risk of and worry about other diseases. Men who attended prostate cancer-screening appointments at a general urology practice (n = 209) were given a brief anonymous self-report measure. Structural equation modeling (LISREL) results indicated: (1) perceived risk of prostate cancer mediated the relationship between family history of prostate cancer and prostate cancer worry; (2) perceived risk of other diseases increased perceived risk of prostate cancer; and (3) prostate cancer worry and increased other disease worry.

Translational research is needed to explore how people will respond to personal genetic susceptibility information related to common health conditions. Maximizing the rigor of this research will require that genetic test results be returned to study participants. Currently, there is no established method that guides the selection of genetic variants to be used in research with these objectives.
Methods and Results
To address this question, we designed a process to identify gene variants and health conditions to be included in a prototype genetic test for use in a larger research effort, the Multiplex Initiative. The intention of this exploration was to facilitate research that generates individual genetic test results that are returned to study participants. Inclusion criteria were developed as part of a transdisciplinary and iterative process that considered the weight of evidential support for genetic association with common health conditions, the appropriateness of use in human subjects research, and the recommendations of expert peer reviewers.
The selection process was designed to identify gene variants for the limited purpose of translational research and, therefore, should not be seen as producing a valid clinical test. However, this example of an applied selection process may provide guidance for researchers who are designing studies to evaluate the implications of genetic susceptibility testing through the return of personalized genetic information. As the rate of genomic discoveries increases, such research will be essential in steering the translation of this information towards the greatest public health benefit.

The identification of genetic variants associated with common disease is accelerating rapidly. “Multiplex tests” that give individuals feedback on large panels of genetic variants have proliferated. Availability of these test results may prompt consumers to use more healthcare services.
To examine whether offers of multiplex genetic testing increases healthcare utilization among healthy patients aged 25–40.
1,599 continuously insured adults aged 25–40 were surveyed and offered a multiplex genetic susceptibility test (MGST) for eight common health conditions.
Main Outcome Measure
Healthcare utilization from automated records was compared in 12 month pre- and post-test periods among persons who completed a baseline survey only (68.7%), those who visited a study Web site but opted not to test (17.8%), and those who chose the MGST (13.6%).
In the pre-test period, persons choosing genetic testing used an average of 1.02 physician visits per quarter compared to 0.93 and 0.82 for the other groups (p<0.05). There were no statistically significant differences by group in the pre-test use of any common medical tests or procedures associated with four common health conditions. When changes in physician and medical test/procedure use in the post-test period were compared among groups, no statistically significant differences were observed for any utilization category.
Persons offered and completing multiplex genetic susceptibility testing used more physician visits prior to testing, but testing was not associated with subsequent changes in use. This study supports that multiplex genetic testing offers can be provided directly to patients in such a way that use of health services are not inappropriately increased.

To describe parents' attitudes toward pediatric genetic testing for common, adult-onset health conditions and to identify factors underlying these attitudes.
PARTICIPANTS AND METHODS:
Parents (n = 219) enrolled in a large, group-practice health plan were offered a “multiplex” genetic test for susceptibility to 8 common, adult-onset health conditions and completed an online survey assessing attitudes and beliefs about the risks and benefits of the test for their child, their willingness to consider having their child tested, and other psychosocial variables.
Parents viewed the benefits of pediatric testing to outweigh its risks (positive decisional balance) and were moderately interested in pediatric testing. Variables associated with positive decisional balance included greater interest in knowing about gene-health associations in their child, anticipation of less difficulty understanding their child's genetic health risks, and more positive emotional reactions to learning about their child's decreased health risks (adjusted R2 = 0.33, P < .0001). Similarly, variables associated with greater parental willingness to test were being a mother (versus being a father), greater perceived risk of diseases in their child, greater interest in knowing about gene-health relationships in their child, anticipating less difficulty learning about their child's genetic health risks, anticipating more positive emotional reactions to learning about their child's decreased health risks, and positive decisional balance (adjusted R2 = 0.57, P < .0001).
As genetic susceptibility testing for common, adult-onset health conditions proliferates, pediatricians should anticipate parents' interest in testing children and be prepared to facilitate informed decision making about such testing.

The aim was to compare the psychological impact of a multidisciplinary specialist genetics service with surgical provision in women at high risk and those at lower risk of familial breast cancer. Women (n=735) were randomized to a surgical consultation with (trial group) or without (control group) specialist genetic risk assessment and the possible offer of presymptomatic genetic testing. Participants completed questionnaires before and immediately after the consultation to assess anxiety, cancer worry, perceived risk, interest in genetic testing and satisfaction. Responses of subgroups of women stratified by clinicians as low, moderate, or high risk were analyzed. There were no significant main effects of study intervention on any outcome variable. Regardless of risk information, there was a statistically significant reduction in state anxiety (P<0.001). Reductions in cancer worry and perceived risk were significant for women at low or moderate risk (P<0.001) but not those at high risk, and satisfaction was significantly lower in the high risk group (P<0.001). In high risk women who received specialist genetic input, there was a marginally significant trend towards increased perceived risk. The effect of risk information on interest in genetic testing was not significant. Breast care specialists other than geneticists might provide assessments of breast cancer risk, reassuring women at reduced risk and targeting those at high risk for specialist genetic counselling and testing services. These findings are discussed in relation to the existing UK Calman-Hine model of service delivery in cancer genetics.

The current study has two aims: (1) to look at people's recall of risk information after genetic counselling and (2) to determine the impact of receiving an audiotape of the genetic consultation on level of recall, cancer related worry, and women's uptake of risk management methods. Using a prospective randomised controlled design, subjects receiving an audiotape were compared with a standard consultation group. Participants were drawn from attenders at the genetic clinics of two London hospitals and included 115 women with a family history of breast cancer. Assessment of perceived genetic risk, mental health, cancer worry, and health behaviour was made before counselling at the clinic (baseline) and by postal follow up. Usefulness of audiotapes and satisfaction with the clinical service was assessed by study specific measures. The data indicate that cancer worry is reduced by provision of an audiotape of the genetic consultation. Recall of the genetic risk figure, however, is not affected by provision of an audiotape and neither is it related to women's overall perception of being more or less at risk of breast cancer than the average woman. Forty-one percent of women accurately recalled their personal risk of breast cancer at one month follow up; however, 25% overestimated, 11% underestimated, and 23% could not remember or did not know their breast cancer risk. Recall of the risk figure is more accurate when the clinical geneticist has given this to the woman as an odds ratio rather than in other formats. Subsequent health behaviour is unaffected by whether women have an audiotape record of their genetic consultation. Results suggest that having a precise risk figure may be less important than women taking away from the consultation an impression that something can be offered to help them manage that risk. Provision of an audiotape of the consultation is of limited usefulness. The need for psychological care to be better integrated into genetic counselling at cancer family clinics was highlighted by the study. The results are discussed in terms of future service development.
Susceptibility testing for common, complex adult-onset diseases is projected to become more commonplace as the rapid pace of genomic discoveries continues, and evidence regarding the potential benefits and harms of such testing is needed to inform medical practice and health policy. Apolipoprotein E (APOE) testing for risk of Alzheimer’s disease (AD) provides a paradigm in which to examine the process and impact of disclosing genetic susceptibility for a prevalent, severe and incurable neurological condition. This review summarizes findings from a series of multi-site randomized clinical trials examining psychological and behavioral responses to various methods of genetic risk assessment for AD using APOE disclosure. We discuss challenges involved in disease risk estimation and communication and the extent to which participants comprehend and perceive utility in their genetic risk information. Findings on the psychological impact of test results are presented (e.g., distress), along with data on participants’ health behavior and insurance purchasing responses (e.g., long term care). Finally, we report comparisons of the safety and efficacy of intensive genetic counseling approaches to briefer models that emphasize streamlined processes and educational materials. The implications of these findings for the emerging field of personal genomics are discussed, with directions identified for future research.
Genomic testing for common genetic variants associated with skin cancer risk could enable personalized risk feedback to motivate skin cancer screening and sun protection.
In a cross-sectional study, we investigated whether skin cancer cognitions and behavioral factors, sociodemographics, family factors, and health information-seeking were related to perceived importance of learning about how (a) genes and (b) health habits affect personal health risks using classification and regression trees (CART).
The sample (n = 1,772) was collected in a large health maintenance organization as part of the Multiplex Initiative, ranged in age from 25–40, was 53% female, 41% Caucasian, and 59% African-American. Most reported that they placed somewhat to very high importance on learning about how genes (79%) and health habits (88%) affect their health risks. Social influence actors were associated with information-seeking about genes and health habits. Awareness of family history was associated with importance of health habit, but not genetic, information-seeking.
The investment of family and friends in health promotion may be a primary motivator for prioritizing information-seeking about how genes and health habits affect personal health risks and may contribute to the personal value, or personal utility, of risk information. Individuals who seek such risk information may be receptive to interventions aimed to maximize the social implications of healthy lifestyle change to reduce their health risks.

The aim of this multi-centre UK study is to examine the attributes of a cohort offered predictive genetic testing for breast/ovarian cancer predisposition. Participants are adults unaffected with cancer from families with a known BRCA1/2 mutation. This is the first large multi-centre study of this population in the UK. The study evaluates mental health, perceived risk of developing cancer, preferred risk management options, and motivation for genetic testing. Participants were assessed when coming forward for genetic counselling prior to proceeding to genetic testing. Three hundred and twelve individuals, 76% of whom are female, from nine UK centres participated in the study. There are no gender differences in rates of psychiatric morbidity. Younger women (<50 years) are more worried about developing cancer than older women. Few women provide accurate figures for the population risk of breast (37%) or ovarian (6%) cancer but most think that they are at higher risk of developing breast (88%) and ovarian (69%) cancer than the average woman. Cancer related worry is not associated with perceived risk or uptake of risk management options except breast self-examination. The findings indicate that younger women may be particularly vulnerable at the time of the offer of a predictive genetic test.

Perceived risk is a complex concept that influences the genetic counseling process and can affect client coping and behavior. Although the association between family history and risk perception is well recognized in the literature, no studies have explored this relationship specifically in those seeking genetic susceptibility testing for a common chronic condition. REVEAL is a randomized trial assessing the impact of APOE disclosure and genetic risk assessment for Alzheimer’s disease (AD). Using baseline REVEAL data, we hypothesized that there would be a significant association between the degree of AD family history and risk perception of AD, and that this relationship would be stronger in those who believed that genetics is a very important AD risk factor. In our sample of 293 participants, we found that a higher self-perceived risk of AD was associated with strength of family history of AD (p<0.001), belief in genetics as an important AD risk factor (p<0.001), being female (p<0.001) and being Caucasian (p=0.02). These results are the first to demonstrate the association between family history and risk perception in persons volunteering for genetic susceptibility testing for a common complex disease.

Limited empirical data are available on the effects of genetic counseling and testing among African American women.
To evaluate the effects of genetic counseling and testing in African American women based on different levels of exposure: (a) women who were randomized to culturally tailored (CTGC) and standard genetic counseling (SGC) to women who declined randomization (non-randomized group), (b) participants and non-participants in genetic counseling, and (c) BRCA1 and BRCA2 (BRCA1/2) test result acceptors and decliners.
Randomized trial of genetic counseling conducted from February 2003 to November 2006.
We evaluated changes in perceived risk of developing breast cancer and cancer worry.
Women randomized to CTGC and SGC did not differ in terms of changes in risk perception and cancer worry compared to decliners. However, counseling participants had a significantly greater likelihood of reporting reductions in perceived risk compared to non-participants (p = 0.03). Test result acceptors also had a significantly greater likelihood of reporting decreases in cancer worry (p = 0.03). However, having a cancer history (p = 0.03) and a BRCA1/2 prior probability (p = 0.04) were associated with increases in cancer worry.
Although CTGC did not lead to significant improvements in perceived risk or psychological functioning, African American women may benefit from genetic counseling and testing. Continued efforts should be made to increase access to genetic counseling and testing among African American women at increased risk for hereditary disease. But, follow-up support may be needed for women who have a personal history of cancer and those with a greater prior probability of having a BRCA1/2 mutation.

To examine the relation of children's pain severity, perceived pain threat, and passive coping to maternal worry and family activities.
We assessed pain severity, perceived threat (conceptualized as beliefs about pain seriousness and coping ability), and coping strategies in 130 patients with chronic abdominal pain. Mothers rated the impact of the child's health on maternal worry and family activities.
Controlling for pain severity, higher pain threat was associated with maternal reports of greater worry and limitations in family activities due to the child's health. Children's use of passive-coping strategies was not related to maternal worry or family activity limitations.
Health care providers should assess patients’ pain beliefs, correct misperceptions about pain seriousness, and help increase patients’ perceived efficacy in coping with pain.

Past research has suggested that dispositional cancer worry may be a key predictor of health behavior. The present study examined seven measures of dispositional cancer worry to see if they were significantly related (convergent validity), significantly different from similar but distinct traits (divergent validity), and capable of predicting cancer-relevant outcomes (predictive validity).
489 undergraduate students completed a survey measuring dispositional worry, dispositional cancer worry, and perceived cancer risk.
Factor analysis identified four underlying dimensions that explained 67.3% of the variance in dispositional cancer worry: severity (42.8%), frequency (12.3%), psychological reactance (6.9%), and worry impact (5.3%). Four existing measures of dispositional cancer worry were found to represent each of these dimensions. In general, dispositional cancer worry measures were highly correlated with one another and only moderately correlated with measures of dispositional worry, supporting strong convergent and divergent validity. Hierarchical regression analyses revealed that dispositional cancer worry measures predicted significant variance in cancer-relevant outcomes above and beyond dispositional worry.
The results of this study support the notion that dispositional cancer worry and dispositional worry are distinct constructs. Furthermore, two dimensions of dispositional cancer worry (severity and frequency) seemed to have the strongest convergent, divergent, and predictive validity.

To determine whether unique groups of adult childhood cancer survivors could be defined on the basis of modifiable cognitive, affective and motivation indicators. Secondary objectives were to examine to what extent group membership covaried with more static variables (e.g., demographics, disease, and treatment) and predicted intent for subsequent medical follow-up.
Using latent class analysis of data from 978 participants (ages 18–52 years; mean, 31; SD, 8) in the Childhood Cancer Survivor Study, we classified survivors according to their worries about health, perceived need for follow-up care, health motivation, and background variables. Intent to participate in medical follow-up, as a function of class membership, was tested using equality of proportions.
The best-fitting model (BIC=18,540.67, BLMRT=<0.001) was characterized by three distinctive survivor classes (worried, 19%; self-controlling, 26%; collaborative, 55%) and three significant class covariates (gender, perceptions of health and severity of late effects). A smaller proportion of survivors in the self-controlling group [81%] than in the worried [90%] (P=0.015) and collaborative [88%] (P=0.015) groups intended to obtain a routine medical checkup. A smaller proportion of survivors in the self-controlling group [32%] than in the collaborative [65%] (P=<0.001) and worried [86%] (P=<0.001) groups planned a cancer-related check-up. A smaller proportion of survivors in the collaborative group [65%] than in the worried group [86%] (P=<0.001) were likely to obtain a cancer-related check-up.
Childhood cancer survivors can be classified according to modifiable indicators. The classification is distinctive, predicts intent for future medical follow-up, and can inform tailored interventions.

We tested whether adding interpretive labels (e.g., “negative test”) to prenatal genetic screening test results changes perceived risk and preferences for amniocentesis.
Women (N=1,688) completed a hypothetical pregnancy scenario via the Internet. We randomized participants into two groups: high (12.5/1000) risk of fetal chromosomal problems or low (2/1000) risk. After prenatal screening, estimated risk was identical (5/1000) for all participants, but results were provided either alone or with interpretive labels.
When receiving test results without labels, all participants react similarly. With labels, participants receiving “positive” or “abnormal” results reported higher perceived risk (p<0.001), greater worry (p<0.001), and greater interest in amniocentesis (57% vs. 37%, p<0.001) than those receiving “negative” or “normal” results.
Interpretive labels for test results can induce larger changes to women’s risk perceptions and behavioral intentions than numerical results alone do, creating decision momentum. This finding has broad clinical implications for patient-provider communication.

Advances in technology have made individual access to personal genetic information foreseeable in the near future. Policy makers and the media forecast that the ready availability of personal genetic profiles would benefit both the individual and the health care system by improving outcomes and decreasing cost. However, there is a significant gap between having access to genetic data and either wanting or understanding the information it provides. Objective: Our primary aim was to evaluate, using a population-based sample of healthy adults, whether gender, race and education status influences interest and participation in a multiplex genetic susceptibility test.
Healthy, insured individuals, 25–40 years of age, were approached via a large, integrated health system in which primary and specialty care is available. Study participants were offered personalized genetic risk information on 8 common chronic health conditions. Social groups historically known not to participate in genetic research (men, African Americans and those from lower education neighborhoods) were oversampled. We describe the recruitment outcomes and testing decisions of these social groups.
We found that even among those with access to health care, African Americans were less likely to participate in the multiplex genetic susceptibility test, while those from higher education neighborhoods were more likely to participate.
Our results suggest that large social groups will likely be underrepresented in research in personalized genomics even when robust population-based recruitment strategies are employed.

Few studies have compared perceptions of risk, worry, severity and control across multiple diseases. This paper examines how these perceptions vary for heart disease, diabetes, stroke, and colon, breast, and ovarian cancers.
The data for this study came from the Family Healthware™ Impact Trial (FHITr), conducted in the United States from 2005 to 2007. Healthy adults (N = 2362) from primary care practices recorded their perceptions at baseline for each disease. Analyses were conducted controlling for study site and personal risk factors.
Perceived risk was significantly higher for cancers than for other diseases. Men worried most about getting heart disease; women worried most about getting breast cancer, followed by heart disease. Diabetes was perceived to be the least severe condition. Heart disease was perceived to be the most controllable compared to cancers, which were perceived to be the least controllable. Women had higher perceived risk and worry ratings compared to men for several diseases.
These data highlight how individuals comparatively view chronic diseases. Addressing prior disease perceptions when communicating multiple disease risks may facilitate an accurate understanding of risk for diseases, and help individuals to effectively identify and engage in relevant behaviors to reduce their risk.

Understanding population responses to influenza helps optimize public health interventions. Relevant theoretical frameworks remain nascent.
To model associations between trust in information, perceived hygiene effectiveness, knowledge about the causes of influenza, perceived susceptibility and worry, and personal hygiene practices (PHPs) associated with influenza.
Cross-sectional household telephone surveys on avian influenza A/H5N1 (2006) and pandemic influenza A/H1N1 (2009) gathered comparable data on trust in formal and informal sources of influenza information, influenza-related knowledge, perceived hygiene effectiveness, worry, perceived susceptibility, and PHPs. Exploratory factor analysis confirmed domain content while confirmatory factor analysis was used to evaluate the extracted factors. The hypothesized model, compiled from different theoretical frameworks, was optimized with structural equation modelling using the A/H5N1 data. The optimized model was then tested against the A/H1N1 dataset.
The model was robust across datasets though corresponding path weights differed. Trust in formal information was positively associated with perceived hygiene effectiveness which was positively associated with PHPs in both datasets. Trust in formal information was positively associated with influenza worry in A/H5N1 data, and with knowledge of influenza cause in A/H1N1 data, both variables being positively associated with PHPs. Trust in informal information was positively associated with influenza worry in both datasets. Independent of information trust, perceived influenza susceptibility associated with influenza worry. Worry associated with PHPs in A/H5N1 data only.
Knowledge of influenza cause and perceived PHP effectiveness were associated with PHPs. Improving trust in formal information should increase PHPs. Worry was significantly associated with PHPs in A/H5N1.

The purpose of this paper was to demonstrate how living in neighborhoods with high levels of poverty (while controlling for personal income) impacts personal characteristics which in turn impacts retention of breast cancer risk knowledge and changes in worry and perceived risk.
The data from this project come from a larger NCI funded study that included a pre-test, a breast cancer risk education session, a post-test, the option of an individualized risk assessment via the Gail Model and three follow-up phone calls over the next nine months.
The percent of individuals living below poverty in the community in which the participant resided was predictive of the personal characteristics assessed, and these characteristics were predictive of changes in breast cancer worry, and knowledge across time.
Differentiation of self and monitoring, two of the individual characteristics that appear to allow people to process and use information to make “rational” decisions about health care, appear to be impacted by the necessity for adaptation to a culture of poverty. Thus, as a health care community, we need to tailor our messages and our recommendations with an understanding of the complex intersection of poverty and health care decision making.
This study examined factors that predict psychological morbidity and screening adherence in first-degree relatives (FDRs) taking part in a familial PSA screening study. Prostate cancer patients (index cases – ICs) who gave consent for their FDRs to be contacted for a familial PSA screening study to contact their FDRs were also asked permission to invite these FDRs into a linked psychosocial study. Participants were assessed on measures of psychological morbidity (including the General Health Questionnaire; Cancer Worry Scale; Health Anxiety Questionnaire; Impact of Events Scale); and perceived benefits and barriers, knowledge; perceived risk/susceptibility; family history; and socio-demographics. Of 255 ICs, 155 (61%) consented to their FDRs being contacted. Of 207 FDRs approached, 128 (62%) consented and completed questionnaires. Multivariate logistic regression revealed that health anxiety, perceived risk and subjective stress predicted higher cancer worry (P=0.05). Measures of psychological morbidity did not predict screening adherence. Only past screening behaviour reliably predicted adherence to familial screening (P=0.05). First-degree relatives entering the linked familial PSA screening programme do not, in general, have high levels of psychological morbidity. However, a small number of men exhibited psychological distress.

Previous research has addressed the relationship between customer satisfaction, perceived quality and customer loyalty intentions in consumer markets. In this study, we test and compare three theoretical models of the quality–satisfaction–loyalty relationship in the Chinese healthcare system.
This research focuses on hospital patients as participants in the process of healthcare procurement. Empirical data were obtained from six Chinese public hospitals in Shanghai. A total of 630 questionnaires were collected in two studies. Study 1 tested the research instruments, and Study 2 tested the three models. Confirmatory factor analysis was used to assess the scales’ construct validity by testing convergent and discriminant validity. A structural equation model (SEM) specified the distinctions between each construct. A comparison of the three theoretical models was conducted via AMOS analysis.
The results of the SEM demonstrate that quality and satisfaction are distinct concepts and that the first model (satisfaction mediates quality and loyalty) is the most appropriate one in the context of the Chinese healthcare environment.
In this study, we test and compare three theoretical models of the quality–satisfaction–loyalty relationship in the Chinese healthcare system. Findings show that perceived quality improvement does not lead directly to customer loyalty. The strategy of using quality improvement to maintain patient loyalty depends on the level of patient satisfaction. This implies that the measurement of patient experiences should include topics of importance for patients’ satisfaction with health care services.

Employer-sponsored health risk assessments (HRA) may include laboratory tests to provide evidence of disease and disease risks for common medical conditions. We evaluated the ability of HRA-laboratory testing to provide new disease-risk information to participants.
We performed a cross-sectional analysis of HRA-laboratory results for participating adult employees and their eligible spouses or their domestic partners, focusing on three common health conditions: hyperlipidemia, diabetes mellitus, and chronic kidney disease. HRA with laboratory results of 52,270 first-time participants were analyzed. Nearly all participants had access to health insurance coverage. Twenty-four percent (12,392) self-reported one or more of these medical conditions: 21.1% (11,017) self-identified as having hyperlipidemia, 4.7% (2,479) self-identified as having diabetes, and 0.7% (352) self-identified as having chronic kidney disease. Overall, 36% (n = 18,540) of participants had laboratory evidence of at least one medical condition newly identified: 30.7% (16,032) had laboratory evidence of hyperlipidemia identified, 1.9% (984) had laboratory evidence of diabetes identified, and 5.5% (2,866) had laboratory evidence of chronic kidney disease identified. Of all participants with evidence of hyperlipidemia 59% (16,030 of 27,047), were newly identified through the HRA. Among those with evidence of diabetes 28% (984 of 3,463) were newly identified. The highest rate of newly identified disease risk was for chronic kidney disease: 89% (2,866 of 3,218) of participants with evidence of this condition had not self-reported it. Men (39%) were more likely than women (33%) to have at least one newly identified condition (p<0.0001). Among men, lower levels of educational achievement were associated with modestly higher rates of newly identified disease risk (p<0.0001); the association with educational achievement among women was unclear. Even among the youngest age range (20 to 29 year olds), nearly 1 in 4 participants (24%) had a newly identified risk for disease.
These results support the important role of employer-sponsored laboratory testing as an integral element of HRA for identifying evidence of previously undiagnosed common medical conditions in individuals of all working age ranges, regardless of educational level and gender.
HPV vaccines are available to men but there are few studies investigating the acceptability of HPV vaccines among men who have sex with men (MSM), a high risk group. We assessed the intention to take up HPV vaccines among MSM in Hong Kong and the associated factors related to cognitions on HPV and HPV vaccines, basing on the Health Belief Model (n = 542). The acceptability of HPV vaccines was 20% (unconditional on efficacies and price), 29.2% (conditional on efficacies and market price), 51.7% (conditional on efficacies and discounted price) and 79.1% (conditional on efficacies and free price). Adjusting for background variables, composite scores of perceived susceptibility, perceived severity, perceived barriers and cue to actions were significantly associated with acceptability of HPV vaccines conditional on specific efficacies and the market price. Acceptability of HPV vaccines was highly price sensitive. Future studies need to use conditional measures. Implementation and translational researches are warranted.
