Psychological side effects of breast cancer screening.

Evaluated the impact of receiving abnormal mammogram results on women's anxiety and breast cancer worries and on their breast self-examination (BSE) frequency and intentions to obtain subsequent mammograms. A telephone survey was conducted with 308 women 50 years old and older approximately 3 months following a screening mammogram. Subjects included women with suspicious abnormal mammograms, nonsuspicious abnormal mammograms, and normal mammograms. Women with suspicious abnormal mammograms exhibited significantly elevated levels of mammography-related anxiety and breast cancer worries that interfered with their moods and functioning, despite the fact that diagnostic work-ups had ruled out breast cancer. Women with moderate levels of impairment in mood or functioning were more likely to practice monthly BSE than women with either high or low levels of impairment. Breast cancer worries, perceived susceptibility to breast cancer, and physician encouragement to get mammograms all exhibited independent positive relationships to mammogram intentions.

Cancer risk notification: psychosocial and ethical implications.

Basic and medical science investigations have identified a growing number of risk factors important in carcinogenesis. By communicating cancer risk information in medical practice, we have the potential to motivate high-risk individuals to adhere to cancer prevention and surveillance protocols. However, cancer screening and risk notification might have adverse psychologic and social consequences as well. In this review, we address the psychosocial and ethical implications of cancer risk notification. The literature on the psychosocial impact of cancer screening programs and programs for notifying workers exposed to occupational carcinogens is reviewed critically. In addition, we examine new concerns and responsibilities raised by the emerging field of cancer genetics. Suggestions for future research and for patient education are addressed.

Factors associated with repeat adherence to breast cancer screening.

This study identified barriers and facilitators of repeat participation in mammography and breast physical examination among women ages 50 years and over. Telephone interviews were conducted with 910 women in this age group. Forty percent of respondents had never had a mammogram. Only 38% had had one in the past 12 months. Of women who had a prior mammogram, 43% had had only one. Only 60% of women had had a breast exam in the past 12 months. A physician recommendation was the single best predictor of adherence to mammography. However, only 60% of women reported that their physicians had ever recommended mammography. Several other barriers to mammography were revealed, including anxiety, embarrassment, and concerns about cost and radiation. Both a family history of breast cancer and heightened perceived vulnerability to breast cancer were associated positively with repeat mammography participation; anxiety about screening reduced the likelihood of this outcome. These findings suggest that physicians can play a powerful role in motivating women to participate in initial and subsequent breast cancer screening. Reassurance may reduce women's anxiety and embarrassment and increase utilization further.

Adherence to colorectal cancer screening in an HMO population.

This study aimed to determine factors that influence fecal occult blood test performance in colorectal cancer screening. A random sample was selected of men and women ages 50 to 74 years of age who had been mailed a fecal occult blood testing kit in a screening program in fall 1986. One year after initial test mailing, sample group members (n = 504) were surveyed by telephone. Four months later, the survey sample received a second fecal occult blood test mailing. Multivariable analysis for subjects with validated past fecal occult blood test status (n = 322) revealed the past testing was positively associated with physician encouragement of screening, age, the belief that cancer is curable, perceived test efficacy, and strong intention to do testing. It also was discovered that persons who felt that they had little control over their health were more likely to have done past testing. Preliminary analysis of prospective adherence showed that the strongest statistically significant independent predictor was past test performance. Prospective adherence among past nontesters (n = 121) was associated with expressed commitment to do fecal occult blood testing and reported presence of colorectal cancer risk factors. Analysis of adherence among past testers (n = 201) revealed that belief in colorectal cancer curability and age were significant predictors. The findings reported here indicate that factors influencing adherence among past nontesters differ from those for past testers. Overall, these results suggest that to increase participation in colorectal cancer screening, physicians and other health professionals should (a) deliver educational messages that increase awareness of risk factors for colorectal cancer and curability of the disease, and (b) elicit from potential screenees a commitment to engage in recommended preventive behaviors. It may also be well to consider "tailoring" messages for past nontesters and past testers, respectively, by emphasizing colorectal cancer risk factors and highlighting curability.

Effects of coping style and relaxation on cancer chemotherapy side effects and emotional responses.

This study was designed to determine (a) the relationship of coping style to cancer chemotherapy side effects and (b) whether coping style moderated the impact of a relaxation intervention on anxiety, depression, and nausea associated with chemotherapy. Forty-eight cancer patients were assigned randomly to receive either progressive muscle relaxation training before chemotherapy (experimental group) or standard care (control group). Spearman correlations indicated that a "blunting" or distraction-oriented coping style was associated with less anticipatory anxiety, less depression, and less nausea during and after chemotherapy. Spearman correlations also indicated that a "monitoring" or information-gathering coping style was associated with more anticipatory anxiety, and more nausea before and during chemotherapy. Although there was a significant effect of the relaxation intervention on posttreatment nausea, there were no other between-group differences. The results did suggest, however, that relaxation was effective in reducing anticipatory anxiety among "blunters," but not "monitors," perhaps because relaxation is a distraction strategy and therefore is consistent with a blunting coping style. The effects of coping and relaxation on pretreatment anxiety may have important implications, because anxiety is a key factor in classic conditioning models of anticipatory nausea and vomiting.

The impact of a brief coping skills intervention on adherence to breast self-examination among first-degree relatives of newly diagnosed breast cancer patients.

The present investigation sought to determine (1) the impact of a single session stress management/coping intervention (problem-solving training; PST) versus a general health counseling (GHC) control condition on breast self-examination (BSE) adherence among relatives of newly diagnosed breast cancer patients, and (2) whether women with heightened perceived risk of breast cancer and/or cancer specific distress at baseline were more likely to improve their BSE adherence following PST. The participants were 510 women age 20-75 who had at least one first-degree relative with breast cancer. All of the participants completed a baseline telephone interview, an intervention (PST versus GHC), and a 3-month follow-up telephone interview. The results revealed a 36% overall improvement in BSE adherence, with no significant between-group difference in improvement (chi 2 = 0.03, p = 0.87). The logistic regression analysis of improvement in BSE adherence revealed a statistically significant cancer-specific distress by treatment interaction (p = 0.04). Among women who received PST, those with high levels of cancer-specific distress were two times more likely to improve in BSE adherence than women low in cancer-specific distress. There was no effect of cancer-specific distress in the control condition. These results suggest that women with a family history of breast cancer who have high levels of distress may be most likely to benefit from behavioral coping skills intervention to promote adherence to breast cancer screening.

Psychological issues among children of hereditary breast cancer gene (BRCA1/2) testing participants.

Children growing up in hereditary breast cancer families may experience diminished psychological well-being. In addition to coping with having a cancer-affected parent or close relatives, these children may focus on their own health risks in light of shared genetic information. While knowledge of a parent's BRCA1/2 negative status may allay a subset of children's worries and fears about cancer, others could experience distressing thought patterns over positive test results. The purpose of this preliminary study is to explore conceptions of health, cancer risk, and psychological adjustment among children in families suggestive of carrying BRCA1/2 susceptibility genes. As part of a longitudinal investigation of the outcomes of BRCA1/2 testing in adults, 20 children of a highly select group of 15 mothers (80% previously affected by breast/ovarian cancer) completed a self-report survey of their beliefs and opinions regarding cancer and genetic testing, stress and worry about cancer, and anxiety, depression, and behavior problems. All information was completed at baseline, prior to the mother's receipt of her genetic test result. The data did not suggest unusually elevated cancer worries or psychological adjustment problems in these children at this point in the parental genetic testing process. However, children with more psychological distress symptoms did experience more frequent thoughts of becoming sick and greater cancer worries. To the extent that learning about a parent's positive test result could exacerbate these tendencies, recommendations to promote child psychological and family communications research that monitor such responses are offered.

Translational behavioral research in cancer genetics.

Recent advances in the molecular genetics of cancer have created new opportunities for behavioral scientists interested in decision-making, risk communication, and health behavior. As part of a National Cancer Institute-sponsored workshop, behavioral scientists participated in breakout groups charged with generating suggestions for research priorities. The following five research priorities were identified for the area of genetic testing for cancer susceptibility: (1) enhancing informed decision-making about whether to be tested, (2) improving methods of cancer risk communication, (3) examining the psychosocial, clinical, and economic outcomes of testing, (4) evaluating the efficacy of psychological and behavioral interventions, and (5) evaluating approaches to prevent cancer in mutation carriers. Across each of these areas, family issues, ethnic and cultural issues, and economic implications should be evaluated.

Investigation of mechanisms linking depressed mood to nicotine dependence.

The present study examined the cognitive-behavioral linkages between depressed mood and level of nicotine dependence in smokers seeking smoking cessation treatment. Prior to treatment, 202 subjects completed validated self-report measures of smoking history, depressive symptomatology, "self medication" processes, "learned helplessness" processes, and nicotine dependence. Results revealed that 48% of the study population scored in the "depressed" range on the Center for Epidemiologic Studies (CESD) depression scale. Further, these smokers reported significantly higher levels of nicotine dependence than other nondepressed smokers. Depressed and nondepressed smokers did not differ with respect to several cognitions related to learned helplessness theory. However, depressed smokers were more likely to report "self medication" processes (i.e., negative affect reduction smoking and stimulation smoking). In addition, multivariable regression and path analyses suggested that negative affect reduction smoking and stimulation smoking are sequential mediators of the depression-nicotine dependence relationship. These results underscore the need to screen for depressive symptomatology among smokers seeking treatment, and to develop cessation treatments that are tailored to the needs of depressed smokers.

Excessive breast self-examination among first-degree relatives of newly diagnosed breast cancer patients. High-Risk Breast Cancer Consortium.

First-degree relatives (FDRs) of women with breast cancer may have heightened anxiety about their personal risk for developing breast cancer. Breast self-examination (BSE) is an important component of risk surveillance for all women. In this study, the authors describe a subset of FDRs who appear to excessively (> or = once per day) perform BSE. These women, who constituted 8% of 1,053 FDRs in this study, were compared with women who did not examine excessively. The excessive self-examiners were older, more frequently African American, and less educated. They were more likely to have an affected daughter and > or = two FDRs with breast cancer. They were significantly more likely to think frequently about breast cancer and to report that such thoughts affected their mood. In a multivariate analysis, three variables had significant independent associations with excessive BSE practice: ethnicity (odds ratio [OR] = 2.3), perceived risk of breast cancer compared with women without a family history (OR = 2.9), and frequency of thoughts about breast cancer (OR = 5.5). The women who practice excessive BSE would benefit from enhanced educational efforts and screening for the presence of psychiatric problems such as anxiety and hypochondriasis.

Genetic susceptibility testing in smoking-cessation treatment: one-year outcomes of a randomized trial.

This study evaluated the long-term impact of genetic susceptibility biomarker feedback on smoking behavior change and symptoms of depression in 426 male and female smokers. Smokers were randomized to one of three smoking-cessation interventions: minimal contact quit-smoking counseling (QSC), QSC + exposure biomarker feedback (EBF), and QSC + EBF + biomarker feedback about genetic susceptibility to lung cancer (SBF). The logistic regression model for quit attempt revealed a significant main effect for treatment such that participants in the SBF group were more than two times more likely to make a quit attempt than participants in the QSC group. There was not a significant difference between EBF and QSC participants. The results also revealed a significant effect for baseline stage of change. Those smokers in the preparation stage at baseline were more than three times more likely to make a quit attempt over the 12 months following treatment. The models for 30-day cessation and follow-up smoking rate revealed no significant main or interacting effects for treatment. A repeated measures analysis of variance revealed a significant main effect for time, indicating that an initial increase in depression in the genetic susceptibility group was not maintained over time. Genetic susceptibility feedback has the intended effects on motivation to quit, but it may need to be delivered within a more intensive smoking-cessation treatment for the heightened motivation to translate into smoking cessation.

Ethnic differences in knowledge and attitudes about BRCA1 testing in women at increased risk.

Informed consent for BRCA1 mutation testing will require adequate knowledge of patterns of inheritance of cancer and the benefits, limitations, and risks of DNA testing. This study examined knowledge about the inheritance of breast cancer and attitudes about genetic testing for breast-ovarian cancer susceptibility in women at increased risk. Knowledge and attitudes were measured in 407 African American and Caucasian women aged 18-75 who had at least one first-degree relative (FDR) with breast and/or ovarian cancer. The average knowledge score was 6.0 out of a total of 11 (S.D. = 2.15). Compared to Caucasian women, African American women had lower levels of knowledge and had more positive attitudes about the benefits of genetic testing. There were no significant ethnic differences in attitudes about the limitations and risks of testing, however, income was negatively associated with this outcome. Ethnic differences in knowledge and attitudes about genetic testing for breast-ovarian cancer risk may be attributable to differences in exposure to genetic information and referral by health care providers.

Interaction between variation in the D2 dopamine receptor (DRD2) and the neuronal calcium sensor-1 (FREQ) genes in predicting response to nicotine replacement therapy for tobacco dependence.

We have previously demonstrated that a functional dopamine D2 receptor promoter variant (DRD2 -141 Ins/Del) predicts response to nicotine replacement therapy (NRT). The present study extends this finding in the same population of 363 NRT-treated subjects, by examining variation in the gene encoding the neuronal calcium sensor-1 protein (FREQ), which functions to regulate D2 receptor desensitization. The results indicate a statistically significant interaction effect of DRD2-141 and FREQ genotypes on abstinence at the end of the NRT treatment phase; 62% of the smokers with at least one copy of the DRD2 -141 Del allele and two copies of the FREQ rs1054879 A allele were abstinent from smoking, compared to 29-38% abstinence rates for other smokers in the trial. This result suggests that the interaction between variation in the DRD2 and FREQ genes, which both encode components of the D2 dopamine receptor signal transduction pathway, impacts the efficacy of NRT.

Discordance between physician and patient perceptions in the treatment of diabetes mellitus: a pilot study of the relationship to adherence and glycemic control.

Glycolsylated hemoglobin (G Hb) levels and data on adherence and patient-provider discordance in beliefs about diabetes were collected from 42 insulin-requiring patients with diabetes. Discordance was calculated for both degree of discordance (absolute amount of disagreement) and direction of discordance (degree to which physician > patient or patient < physician). Patients generally agreed with physicians in perceptions of severity, costs of adherence, and immediate and long-term benefits of adherence. Significant differences were found between these dimensions. Only discordance on long-term benefits of adherence correlated with adherence, with greater discordance related to greater adherence. Discordance on the cost dimension correlated negatively with G Hb, suggesting better glycemic control with greater disagreement. Those who underestimate the cost of adherence show greater adherence. Adherence did not correlate significantly with glycemic control.
