Psychosocial factors associated with the public's willingness to pay for genetic testing for cancer risk: a structural equations model.

An adaptation of Andersen's behavioral model of health services utilization is used to examine the psychosocial and socio-demographic factors that directly and indirectly influence the likelihood of undergoing genetic susceptibility testing for cancer, and the amount of money that individuals would be willing to pay out-of-pocket for such a test. Apart from willingness and likelihood, the model also included perceived benefits and barriers, perceived susceptibility, dispositional optimism, information seeking, family history of cancer, socioeconomic status (SES), and age, and explained 30.3% of the variation in willingness. We found as hypothesized that likelihood of undergoing such tests was central to understanding willingness to pay. Being aware of genetic susceptibility testing for cancer, and talking and seeking information about it was directly associated with an increased chance of being willing to pay more, independent of other indirect associations (effects). Interventions targeting those with a family history of cancer and those with a higher SES should generate more awareness about the potential positive and negative consequences to one's family of testing, and the interface between family history of cancer and perceived susceptibility. Interventions should also motivate people to talk and seek more information about genetic testing for cancer risk to enable them take well-informed decisions.

Disparities in hormone replacement therapy use by socioeconomic status in a primary care population.

The use of hormone replacement therapy (HRT) is a controversial decision for many women, yet few studies have evaluated the socio-demographic, psychological, and behavioral correlates of HRT use. This cross-sectional, mailed survey evaluated the associations of socioeconomic status, preventive health behaviors, knowledge and perceptions about HRT-related risks and benefits with HRT use among 428 women 50-70 years old in Vermont. The overall prevalence of HRT use was 40%. Women of moderate to high income were three times more likely than those of low income to use HRT. HRT use was significantly higher among women whose physician had encouraged use (58%) than among those who received ambivalent recommendations from their physicians (20%). Hysterectomy, higher income, younger age, regular adherence to cervical cancer screening, and recommendation by a provider were significantly associated with HRT use in multivariate analyses. There were no differences in HRT use according to level of concern about heart disease, osteoporosis, or breast cancer. A recommendation by a health care provider is a powerful predictor of HRT use, but disparities in use exist by socioeconomic status. Future research should examine why lower income women are less likely to use HRT and whether the discrepancy is due to inconsistent recommendations by health care providers.

Smoking in correctional facilities: a survey of employees.

OBJECTIVE: To assess level of endorsement and expected consequences of worksite smoking restriction policies among correctional employees. DESIGN: Mailed survey to Vermont state correctional employees. MAIN OUTCOME MEASURES: Support for various policy alternatives for both staff and inmate smoking; expected consequences of restrictive smoking policies and smoking behaviour. PARTICIPANTS: 321 of 640 (50%) state correctional employees responded. RESULTS: Employees were somewhat receptive to smoking restrictions for inmates, but less supportive of staff smoking restrictions. A complete ban on inmate smoking both indoors and outdoors was supported by 56% and 49% of never and ex-smokers, respectively, but only 15% of current smokers (p < 0.01). A similar ban on employee smoking was supported by 38% of never and ex-smokers, but only 3% of current smokers (p < 0.01). Overall, employees were most supportive (52%) of a policy for themselves that banned indoor smoking and restricted it to certain areas outdoors. Current smokers were more likely to expect negative consequences as a result of further restrictions than were never or ex-smokers. CONCLUSIONS: Although our findings are limited by a low response rate, most employees support an indoor ban, but not a total ban on smoking. Employees generally favoured a policy that was slightly more restrictive than the current policy, but were less supportive of tighter smoking restrictions for themselves. However, a more restrictive smoking policy is likely to result in some degree of resistance among current smoking employees, who may require specific attention to address their opposition.

Barriers to fecal occult blood testing and sigmoidoscopy among older Chinese-American women.

PURPOSE: This study examined factors associated with fecal occult blood test (FOBT) and sigmoidoscopy screening use among Chinese-American women age 60 years and older. DESCRIPTION OF STUDY: One hundred women were recruited from senior centers in two metropolitan areas on the east coast of the United States. Participants completed a questionnaire that included sections on demographics, health history, health insurance coverage, FOBT and sigmoidoscopy use, common and cultural barriers to colorectal cancer screening, and acculturation. RESULTS: Logistic regression models found greater acculturation to be a significant predictor of having had a FOBT at least once, and found both greater acculturation and physician recommendation to be significant predictors of having had a sigmoidoscopy at least once. No significant predictors were found for regular adherence to colorectal screening guidelines, which include having undergone an FOBT in the past year and sigmoidoscopy in the past 5 years. CLINICAL IMPLICATIONS: This study found that older Chinese-American women underuse FOBT and sigmoidoscopy screening, as is recommended by the American Cancer Society colorectal cancer screening guidelines. These findings suggest that cultural factors may influence the initiation of colorectal cancer screening for Chinese-American women but are not predictive of adherence to screening over time. Outreach efforts to promote colorectal cancer screening in this population might target women who are less acculturated to facilitate an initial entry into the Western healthcare system to obtain screening.

Cultural barriers to mammography, clinical breast exam, and breast self-exam among Chinese-American women 60 and older.

BACKGROUND: This study examined screening utilization at least once and regular adherence to mammography, clinical breast exam, and breast self-exam among older Chinese-American women. METHOD: One hundred women were recruited from senior centers in two metropolitan cities. Participants completed a questionnaire that included sections on demographics, health history, health insurance coverage, breast cancer screening, common and cultural barriers to screening, and acculturation. RESULTS: Logistic regression models found insurance coverage for mammography and acculturation to be significant predictors of having had a mammogram at least once. Low perceived need/lack of physician recommendation and recency of physical examination were significant predictors of having had a mammogram in the past year. Acculturation and modesty were significant predictors of having had a clinical breast exam at least once, while recency of physical examination was a significant predictor of having had a clinical breast exam in the past year. Reliance on medial professionals for screening and forgetting were significant predictors of having performed breast self-exam at least once, and forgetting was a significant predictor of regular performance of breast self-exam. CONCLUSIONS: These findings suggest that both common and cultural barriers play a role in breast cancer screening among older Chinese-American women, with cultural factors being more influential in the initiation of cancer screening behavior.

A process evaluation model for patient education programs for pregnant smokers.

OBJECTIVE: To describe and apply a process evaluation model (PEM) for patient education programs for pregnant smokers. METHODS: The preparation of a process evaluation plan required each program to define its essential "new" patient assessment and intervention procedures for each episode (visit) of patient-staff contact. Following specification of these core implementation procedures (p) by each patient education program, the PEM, developed by the Smoke-Free Families (SFF) National Program Office, was applied. The PEM consists of five steps: (1) definition of the eligible patient sample (a); (2) documentation of patient exposure to each procedure (b); (3) computation of procedure exposure rate (b/a = c); (4) specification of a practice performance standard for each procedure (d); (5) computation of an implementation index (c/d = e) for each procedure. The aggregate of all indexes (e) divided by the number of procedures (P(n)) produced a program implementation index (PII = Sigmae/P(n)). PARTICIPANTS AND SETTINGS: Data from four SFF studies that represent different settings were used to illustrate the application of the PEM. RESULTS: All four projects encountered moderate to significant difficulty in program implementation. As the number and complexity of procedures increased, the implementation index decreased. From initial procedures that included patient recruitment, delivery of the intervention components, and conducting patient follow ups, a variety of problems were encountered and lessons learned. CONCLUSION: This process evaluation provided specific insight about the difficulty of routine delivery of any new methods into diverse maternity care setting. The importance of pilot testing all procedures is emphasised. The application of the PEM to monitor program progress is recommended and revisions to improve program delivery are suggested.

Predictors of intentions to stop smoking early in prenatal care.

OBJECTIVE: To determine baseline variables associated with low intentions of stopping smoking early in pregnancy. DESIGN: Cross sectional survey. PARTICIPANTS: Pregnant smokers pooled across seven Smoke-Free Families trials (n = 1314). RESULTS: 36% of pregnant smokers had low intentions of stopping smoking within the next 30 days. In contrast to pregnant smokers with higher intentions of quitting, pregnant smokers with low intentions were less confident in their ability to quit, less likely to have private health insurance, and less likely to agree that smoking harms the unborn child. They were more likely to smoke heavily, more likely to have fewer years of education, and more likely to have friends and family members who smoke. CONCLUSIONS: Three options to smoking cessation assistance are proposed for pregnant smokers with low intentions of quitting: targeting, triage, and tailoring. Further research is needed to determine which approach is most appropriate.

Free nicotine patches plus proactive telephone peer support to help low-income women stop smoking.

BACKGROUND: This study tested the impact of free nicotine patches plus proactive telephone peer support to help low-income women stop smoking. METHODS: A total of 214 Medicaid-eligible women smokers of childbearing age were randomized to receive free nicotine patches through the mail or free nicotine patches through the mail plus the provision of proactive support by telephone from a woman ex-smoker for up to 3 months. Assessments were conducted by telephone at baseline, 10 days, and 3 and 6 months after enrollment. RESULTS: At the 3-month follow-up, significantly more women in the patch plus proactive telephone support condition were abstinent (42%) compared to the patch only condition (28%) (P = 0.03). Similarly, more women in the experimental condition were abstinent at both the 10-day and 3-month assessments (32 v 19%, P = 0.02). However, differences were not found at the 6-month follow-up, suggesting that the addition of proactive telephone peer support enhanced short-term, but not long-term cessation. CONCLUSIONS: This is the first study to demonstrate a beneficial effect for the addition of proactive telephone support as an adjunct to free nicotine replacement in a low-income population.

Helping women quit smoking: results of a community intervention program.

OBJECTIVES: This intervention was implemented to reduce the prevalence of cigarette smoking among women. METHODS: We used community organization approaches to create coalitions and task forces to develop and implement a multicomponent intervention in 2 counties in Vermont and New Hampshire, with a special focus on providing support to help women quit smoking. Evaluation was by pre-intervention and post-intervention random-digit-dialed telephone surveys in the intervention counties and the 2 matched comparison counties. RESULTS: In the intervention counties, compared with the comparison counties, the odds of a woman being a smoker after 4 years of program activities were 0.88 (95% confidence interval = 0.78, 1.00) (P = .02, 1-tailed); women smokers' perceptions of community norms about women smoking were significantly more negative (P = .002, 1-tailed); and the quit rate in the past 5 years was significantly greater (25.4% vs 21.4%; P = .02, 1-tailed). Quit rates were significantly higher in the intervention counties among younger women (aged 18 to 44 years); among women with household annual incomes of $25,000 or less; and among heavier smokers (those who smoked 25 or more cigarettes daily). CONCLUSIONS: In these rural counties, community participation in planning and implementing interventions was accompanied by favorable changes in women's smoking behavior.

The role of health professionals in a community-based program to help women quit smoking.

BACKGROUND: Health professionals are credible sources of smoking cessation advice. This study describes changes in health professionals' reported provision of smoking cessation counseling activities for women during a community health education project that took place in two intervention counties (I) and compares these to reports from health professionals in two similar comparison counties (C). METHODS: Specific smoking cessation activities reported by physicians (I n = 73, C n = 73), dentists (I n = 51, C n = 46), dental hygienists (I n = 38, C n = 44), family planning and WIC (Special Supplemental Food Program for Women, Infants and Children) counselors (I n = 14 C n = 16), and community mental health counselors (I n = 57, C n = 23) were assessed by mailed surveys at baseline, after 4 years of countywide interventions, and 2 years later. RESULTS: Compared with health professionals in the comparison counties, significant increases in smoking cessation training (P < 0.01) and in reported referral of women to stop smoking groups, support groups, and one-to-one support were noted for physicians, family planning, and WIC counselors (P < 0.001); in training and referral to stop smoking groups and support groups by dentists and dental hygienists (P < 0.05); and in referral to support groups by community mental health counselors (P < 0.05). Significant increases in setting quit dates (P < 0.05) and providing self-help materials (P < 0.01) were also noted for family planning and WIC counselors. These effects were no longer demonstrable 2 years after external support for the countywide interventions was withdrawn. CONCLUSIONS: We suggest that an important aspect of facilitating consistent smoking cessation advice and counseling from health professionals in the future will be the provision of a broader range of regularly available smoking cessation support systems within communities than is generally available at this time in the United States.

Likelihood of undergoing genetic testing for cancer risk: a population-based study.

BACKGROUND: Studies on public perceptions of genetic susceptibility testing for cancer risks are few and tend to focus on specific cancer risks of higher-risk populations, ignoring the general population and their perceived risk of getting any cancers. This study develops and tests a psychosocial model of the proximal and distal influences on likelihood of undergoing genetic susceptibility testing for cancer risk among a population-based sample. METHODS: The sample consisted of 622 adults aged 18-75 interviewed by telephone. The survey instrument included measures derived from the Health Belief Model and adaptations of existing measures from the literature. Data were analyzed using structural equation modeling techniques. RESULTS: The model suggested independent main effects for perceived benefits, perceived barriers, perceived susceptibility, and pessimism while simultaneously accounting for the effects of age, socioeconomic status, family history of cancer, and awareness of the existence of genetic susceptibility testing for cancer risk. The model explained 34% of the variance in likelihood. CONCLUSIONS: While perceived benefits, perceived barriers, perceived susceptibility, and pessimism may directly impact likelihood, they may also mediate the effects of age, socioeconomic status, family history of cancer, and awareness of cancer genetic susceptibility testing, on likelihood.

Outcomes of a randomized community-level HIV prevention intervention for women living in 18 low-income housing developments.

OBJECTIVES: Women in impoverished inner-city neighborhoods are at high risk for contracting HIV. A randomized, multisite community-level HIV prevention trial was undertaken with women living in 18 low-income housing developments in 5 US cities. METHODS: Baseline and 12-month follow-up population risk characteristics were assessed by surveying 690 women at both time points. In the 9 intervention condition housing developments, a community-level intervention was undertaken that included HIV risk reduction workshops and community HIV prevention events implemented by women who were popular opinion leaders among their peers. RESULTS: The proportion of women in the intervention developments who had any unprotected intercourse in the past 2 months declined from 50% to 37.6%, and the percentage of women's acts of intercourse protected by condoms increased from 30.2% to 47.2%. Among women exposed to intervention activities, the mean frequency of unprotected acts of intercourse in the past 2 months tended to be lower at follow-up (mean = 4.0) than at baseline (mean = 6.0). These changes were corroborated by changes in other risk indicators. CONCLUSIONS: Community-level interventions that involve and engage women in neighborhood-based HIV prevention activities can bring about reductions in high-risk sexual behaviors.

The role of cultural variables in breast self-examination and cervical cancer screening behavior in young Asian women living in the United States.

This study examined cultural factors as predictors of breast self-examination (BSE) and participation in cervical cancer screening in young Asian and Caucasian women in the United States. Comparisons between Asian and Caucasian samples revealed significant differences in ever performing BSE and obtaining a pap test; the Caucasian women reported higher participation in both behaviors. Factor analysis of cultural barriers to screening revealed four factors: communication with mother, openness around sexuality, prevention orientation, and utilization of Western medicine. Logistic regression predicting BSE performance from demographics, acculturation, and cultural barriers revealed openness around sexuality to be a significant predictor. Pap test participation was predicted by year in college, ever having engaged in sexual intercourse, prevention orientation, and global acculturation. Cultural factors should be considered in programs to enhance participation in cancer screening.

Community-based promotion of breast screening using small group education.

Small Group Education (SGE) to promote breast cancer screening was implemented in a community-wide program. Based on diffusion of innovations theory, SGE initially was directed toward women at higher occupation and education levels and then progressively shifted toward more vulnerable populations of women at risk of not getting screening. During the four-year intervention, 116 volunteers led SGE presentations, with 8,184 women participating in 740 groups at work sites, organizations, residences, and churches. High participation in SGE and positive participant responses suggest that delivery of SGE using a social diffusion model was an effective method for reaching women throughout the community.

Smoking relapse prevention during pregnancy. A trial of coordinated advice from physicians and individual counseling.

INTRODUCTION: Our objective was to examine the efficacy of physicians' advice and referral to individual counseling in preventing relapse to smoking among women who were smokers early in pregnancy, but quit prior to their first prenatal visit. DESIGN: A randomized controlled trial of prompted physician's advice and individual relapse prevention counseling during pregnancy compared to usual physician advice. Smoking status was assessed by self-report, exhaled carbon monoxide, and urinary cotinine during pregnancy and by self-report 1 year postpartum. RESULTS: There were no significant differences in relapse rates between the intervention and usual-care groups during pregnancy, nor at 1 year postpartum. Relapse rates were 23% in both groups at the 36-week visit, and 32% and 22%, respectively, 1 year postpartum. Younger age, higher motivation to resume smoking, and higher levels of exhaled carbon monoxide at the first prenatal visit were predictive of relapse to smoking during pregnancy. With the conservative assumption that all those lost to follow-up relapsed, the combined 1-year postpartum relapse rate, 51%, was 17 percentage points lower than we observed in an earlier relapse prevention trial, and 15 percentage points lower than that observed nationally a decade earlier. CONCLUSION: Prompting physicians to provide supportive advice combined with referral to individual relapse prevention counseling did not reduce smoking relapse rates during pregnancy, or postpartum. However, the level of attention paid to smoking by physicians in both intervention and usual-care groups during pregnancy may have contributed to the relatively low relapse rates seen 1-year postpartum.

Reducing smoking during pregnancy and postpartum: physician's advice supported by individual counseling.

BACKGROUND: Physicians' advice to help pregnant women quit smoking during prenatal care has had mixed results. Training and prompting physicians to provide consistent advice and referral to on-site support might improve cessation rates. METHODS: Pregnant women who smoked were randomly assigned to receive structured advice from their physician and referral to individual behavior change counseling during prenatal care or to receive brief advice to stop smoking and a quit smoking booklet at their first visit. Smoking status was measured by self-report, exhaled carbon monoxide, and urinary cotinine. RESULTS: Compared with usual care, greater proportions of intervention group women reported not smoking at the 36th-week visit (14% vs 10%) and at 1 year postpartum (18% vs 11%), but these differences were not significant. However, significantly greater proportions of intervention group women reported either not smoking or reducing their cigarette consumption by 50% or more at their second visit (43% vs 29%, P = 0.02), at their 36th-week visit (40% vs 25%, P < 0.01), and at 1 year postpartum (26% vs 14%, P = 0.02). CONCLUSIONS: Physician training on how to gain a pregnant smoker's commitment to change her smoking behavior, an office prompt system, and individualized smoking behavior change counseling show promise in reducing smoking during pregnancy and postpartum, but practical methods to assist pregnant smokers between regular prenatal visits, as they attempt to quit, need to be developed.

Predictors of state legislators' intentions to vote for cigarette tax increases.

BACKGROUND: This study analyzed influences on state legislators' decisions about cigarette tax increase votes using a research strategy based on political science and social-psychological models. METHODS: Legislators from three states representing a spectrum of tobacco interests participated in personal interviews concerned with tobacco control legislation (n = 444). Measures of potential predictors of voting intention were based on the consensus model of legislative decision-making and the theory of planned behavior. Multiple logistic regression methods were used to identify social-psychological and other predictors of intention to vote for cigarette tax increases. RESULTS: General attitudes and norms concerning cigarette tax increases predicted legislators' intention to vote for cigarette tax increases. More specific predictors included perceptions of public health impact and retail sales impact of cigarette tax increases. Constituent pressure was the strongest perceived social influence. Political party and state also were strong predictors of intention. Results were consistent with related research based on political science models. CONCLUSIONS: Legislators' votes on cigarette tax increases may be influenced by their perceptions of positive and negative outcomes of a cigarette tax increase and by perceived constituent pressures. This research model provides useful insights for theory and practice and should be refined in future tobacco control research.
