Objective-Meta-analysis was used to synthesize results of studies on emotional consequences of predictive genetic testing for BRCA1/2 mutations conferring increased risk of breast and ovarian cancer.Design-Studies assessing anxiety or cancer-specific distress before and after provision of test results (k = 20) were analyzed using a random-effects model. Moderator variables included country of data collection and personal cancer history of study participants.Main Outcome Measures-Standardized mean gain effect sizes were calculated for mutation carriers, noncarriers, and those with inconclusive results over short (0-4 weeks), moderate (5-24 weeks), or long (25-52 weeks) periods of time following testing.Results-Distress among carriers increased shortly after receiving results and returned to pretesting levels over time. Distress among noncarriers and those with inconclusive results decreased over time. Some distress patterns differed in studies conducted outside the US and for individuals with varying cancer histories. Conclusion-Resultsunderscore the importance of time; changes in distress observed shortly after test-result disclosure frequently differed from the pattern of distress seen subsequently. Although emotional consequences of this testing appear minimal, it remains possible that testing may affect cognitive and behavioral outcomes, which have rarely been examined through meta-analysis. Testing may also affect understudied subgroups differently. Keywordspredictive genetic testing; hereditary breast and ovarian cancer; BRCA1/2 gene mutations; emotional distress; meta-analysis Breast cancer is the most prevalent cancer in women, apart from skin cancer, and is the secondleading cause of women's cancer deaths (American Cancer Society, 2007; US Cancer Statistics Working Group, 2006). As many as 10% of breast cancers are due to heredity (Claus, Schildkraut, Thompson, & Risch, 1996), with the majority caused by mutations in the tumor suppressor genes BRCA1 (Miki et al., 1994) or BRCA2 (Wooster et al., 1995). Female BRCA1/2 gene mutation carriers have a 35-84% chance of developing breast cancer, and a 10-Correspondence concerning this article should be addressed to Marci Lobel, Department of Psychology, Stony Brook University, Stony Brook, NY 11794-2500. marci.lobel@stonybrook.edu.

The present study investigated coping in early, mid-, and late pregnancy in 321 ethnically and socioeconomically diverse women of varying medical risk. The goal was to determine how women cope with stress across pregnancy and to explore the association of coping with maternal characteristics, stress perceptions, disposition, and social support. Factor analysis of the Revised Prenatal Coping Inventory revealed three distinct types of coping: Planning-Preparation, Avoidance, and Spiritual-Positive Coping. Spiritual coping was used most frequently during pregnancy; avoidant coping was used least often. As hypothesized, use of spiritual coping and avoidance differed across pregnancy. Planning was used more consistently across time. Multivariate regression analyses revealed that the strongest predictors of planning were high optimism and pregnancy-specific distress. Avoidance was most strongly predicted by high state anxiety and pregnancy-specific distress. Greater religiosity and optimism were the strongest predictors of spiritual coping. These results add to a body of evidence that women use distinctive and varied strategies to manage stress prenatally. They also suggest that coping is responsive to changing demands across pregnancy and reflective of women's characteristics, perceptions, and social situations.
BACKGROUND: Primary care providers (PCPs) can play a critical role in helping patients receive the preventive health benefits of cancer genetic risk information. Thus, the objective of this systematic review was to identify studies of US PCPs' knowledge, attitudes, and communication-related behaviors regarding genetic tests that could inform risk-stratification approaches for breast, colorectal, and prostate cancer screening in order to describe current findings and research gaps. METHODS: We conducted a systematic search of six electronic databases to identify peer-reviewed empirical articles relating to US PCPs and genetic testing for breast, colorectal, or prostate cancer published in English from 2008 to 2016. We reviewed these data and used narrative synthesis methods to integrate findings into a descriptive summary and identify research needs. RESULTS: We identified 27 relevant articles. Most focused on genetic testing for breast cancer (23/27) and colorectal cancer risk (12/27); only one study examined testing for prostate cancer risk. Most articles addressed descriptive research questions (24/27). Many studies (24/27) documented PCPs' knowledge, often concluding that providers' knowledge was incomplete. Studies commonly (11/27) examined PCPs' attitudes. Across studies, PCPs expressed some concerns about ethical, legal, and social implications of testing. Attitudes about the utility of clinical genetic testing, including for targeted cancer screening, were generally favorable; PCPs were more skeptical of direct-to-consumer testing. Relatively fewer studies (9/27) examined PCPs' communication practices regarding cancer genetic testing. DISCUSSION: This review indicates a need for investigators to move beyond descriptive research questions related to PCPs' knowledge and attitudes about cancer genetic testing. Research is needed to address important gaps regarding the development, testing, and implementation of innovative interventions and educational programs that can improve PCPs' genetic testing knowledge, assuage concerns about the appropriateness of cancer genetic testing, and promote open and effective patientprovider communication about genetic risk and genetic testing.
Objective Hematopoietic stem cell transplantation (HSCT) is a demanding cancer treatment associated with enduring physical and psychological complications. Survivors' well-being may be further compromised by exposure to chronic stressors common to this population, including difficulties arising from costly medical care, changes in employment status, and health insurance coverage. Thus, we hypothesized that financial, employment, and insurance stressors (collectively referred to as economic survivorship stressors) would be associated with poorer health-related quality of life (HRQOL) among HSCT survivors. Methods Survivors (n=181; M=640 days post-transplant) completed measures of study variables through mailed questionnaires and telephone interviews. Hierarchical regression analyses were conducted to test the hypothesized associations between economic survivorship stressors and HRQOL, and to examine whether social and situational factors interact with survivors' stress perceptions to predict HRQOL. Results Greater financial and employment stress were associated with poorer functioning across multiple HRQOL domains, even after controlling for the effects of possible confounding sociodemographic and medical variables. Insurance stress was not associated with HRQOL. Some associations were moderated by situational factors including timing of the current financial crisis and portion of the transplant paid for by health insurance. Conclusions HSCT survivors can face serious economic challenges during recovery. Results suggest the value of viewing these challenges as chronic stressors capable of reducing survivors' mental and physical well-being. Identifying resources and skills that help survivors cope with these demands is an important goal for clinicians and researchers.
Background: Latinos, whose views are infrequently examined in genomic research, may be at risk of missing out on the benefits of genomic medicine. Aims: To explore this possibility, we conducted a qualitative study of awareness and attitudes about genetic testing among Latinos with lower acculturation in New York City. Methods: We conducted four focus groups (7 English-speaking men, 5 Spanish-speaking men, 13 English-speaking women and 13 Spanish-speaking women) to explore factors that influence the adoption of new innovations through the discussion of genetic testing in general, and a hypothetical vignette describing a genetic test for skin cancer risk, in particular. Results: Through inductive thematic text analysis of focus group transcripts, our multidisciplinary team identified themes within knowledge and attitudes, communication and sources of information, anticipated responses, factors that may increase adoption, and barriers to adoption of genetic testing. Specifically, a majority of participants expressed some degree of uncertainty regarding the purpose of genetic tests and information these tests provide, rarely discussed genetic testing with others in their social networks, and expressed concerns about the misuse of and possible adverse emotional responses to genetic information. However, participants also expressed high levels of interest in receiving a skin cancer genetic test in response to the vignette and believed that receiving actionable health information was a primary reason to consider testing. Gender-based differences in perceived barriers to testing emerged. Conclusions: The results highlight beliefs and barriers that future interventions could target to help ensure that Latinos have adequate understanding of and access to genomic medicine advances.
