The relationship of perceived self-efficacy to quality of life in chronic obstructive pulmonary disease.

From a biomedical perspective, variations in the quality of life of chronic obstructive pulmonary disease (COPD) patients may be attributed to changes in pulmonary function; thus, an increase in lung function should be correlated with an increased score on a health-related quality-of-life measure. However, inconsistent results regarding correlations between various measures of pulmonary function and quality of life have been reported in the literature. The authors evaluated a social cognitive model of quality of life among persons with COPD by analyzing relationships among biomedical measures, self-efficacy measures, and quality-of-life measures in a recursive path model. Path analysis results indicated that the association of pulmonary function and symptoms with quality of life was mediated by perceived self-efficacy for functional activities.

Toward a Model of Prostate Cancer Information Seeking Identifying Salient Behavioral and Normative Beliefs Among African American Men

Public health actions to improve African American mens ability to make informed decisions about participation in prostate cancer control activities have a greater likelihood of success when they are theory driven and informed by members of the target population. This article reports on formative research to evaluate the usefulness of the theory of reasoned action as a model to explain and predict prostate cancer information-seeking behavior by African American men. Fifty-two men participated in eight focus group interviews. Positive behavioral beliefs for obtaining prostate cancer information from physicians included increasing awareness of and obtaining accurate information about the disease, early detection and screening, and treatment. Negative beliefs included fear, distrust, and inconvenience. Significant others, peers, siblings, and religious leaders were identified as individuals who could influence this behavior. These findings provide additional insight into ways to reach and intervene with African American men to influence this important cancer control activity.

Electronic Cigarette Awareness, Use History, and Expected Future Use Among Hospitalized Cigarette Smokers

INTRODUCTION E-cigarette use has surged during the past few years while the debate about the products safety and efficacy for smoking cessation continues. Little is known about the characteristics that distinguish users from nonusers; in this study, we aimed to elucidate these characteristics among hospitalized smokers, a heretofore unstudied population. METHODS Cross-sectional data were collected from cigarette smokers via hospital bedside interviews. Participants reported e-cigarette use status, reasons for use (if used), e-cigarette advertising exposure, expected likelihood of future e-cigarette use, desire to quit smoking, and demographic characteristics. RESULTS Of the 657 English-speaking hospitalized smokers who provided data, 97% reported awareness of e-cigarettes and 46.4% reported e-cigarette use, with 20% reporting use in the previous 30 days. Previous e-cigarette use was significantly more likely among those who were White (odds ratio [OR] = 4.7; confidence interval [CI] = 3.2-6.7), were married/had a domestic partner (OR = 1.5; CI = 1.0-2.2), had more than a high school education (OR = 1.7; CI = 1.1-2.7), had e-cigarette advertising exposure (OR = 1.6; CI = 1.1-2.4), and were younger (OR = 1.3; CI = 1.1-1.5). Expected likelihood of future e-cigarette use was high and positively correlated with desire to quit smoking (Spearmans ρ = .18, p < .0001). CONCLUSIONS Rates of awareness and use of e-cigarettes may be elevated among hospitalized smokers, with more use reported among those who were White, younger, more educated, in a relationship, and exposed to e-cigarette advertising. The association between desire to quit smoking and expected likelihood of future e-cigarette use suggests that cigarette smokers may perceive e-cigarettes as a useful cessation aid.

Internet delivered support for tobacco control in dental practice: randomized controlled trial

Background The dental visit is a unique opportunity for tobacco control. Despite evidence of effectiveness in dental settings, brief provider-delivered cessation advice is underutilized. Objective To evaluate an Internet-delivered intervention designed to increase implementation of brief provider advice for tobacco cessation in dental practice settings. Methods Dental practices (N = 190) were randomized to the intervention website or wait-list control. Pre-intervention and after 8 months of follow-up, each practice distributed exit cards (brief patient surveys assessing provider performance, completed immediately after the dental visit) to 100 patients. Based on these exit cards, we assessed: whether patients were asked about tobacco use (ASK) and, among tobacco users, whether they were advised to quit tobacco (ADVISE). All intervention practices with follow-up exit card data were analyzed as randomized regardless of whether they participated in the Internet-delivered intervention. Results Of the 190 practices randomized, 143 (75%) dental practices provided follow-up data. Intervention practices’ mean performance improved post-intervention by 4% on ASK (29% baseline, adjusted odds ratio = 1.29 [95% CI 1.17-1.42]), and by 11% on ADVISE (44% baseline, OR = 1.55 [95% CI 1.28-1.87]). Control practices improved by 3% on ASK (Adj. OR 1.18 [95% CI 1.07-1.29]) and did not significantly improve in ADVISE. A significant group-by-time interaction effect indicated that intervention practices improved more over the study period than control practices for ADVISE (P = 0.042) but not for ASK. Conclusion This low-intensity, easily disseminated intervention was successful in improving provider performance on advice to quit.

Medication adherence among rural, low-income hypertensive adults: a randomized trial of a multimedia community-based intervention.

Purpose. Examine the effectiveness of a community-based, multimedia intervention on medication adherence among hypertensive adults. Design. Randomized controlled trial. Setting. Rural south Alabama. Subjects. Low-income adults (N = 434) receiving medication at no charge from a public health department or a Federally Qualified Health Center. Intervention. Both interventions were home-based and delivered via computer by a community health advisor. The adherence promotion (AP) intervention focused on theoretical variables related to adherence (e.g., barriers, decisional balance, and role models). The cancer control condition received general cancer information. Measures. Adherence was assessed by pill count. Other adherence-related variables, including barriers, self-efficacy, depression, and sociodemographic variables, were collected via a telephone survey. Analysis. Chi-square analysis tested the hypothesis that a greater proportion of participants in the AP intervention are ≥80% adherent compared to the control group. General linear modeling examined adherence as a continuous variable. Results. Participants receiving the intervention did not differ from individuals in the control group (51% vs. 49% adherent, respectively; p = .67). Clinic type predicted adherence (p < .0001), as did forgetting to take medications (p = .01) and difficulty getting to the clinic to obtain medications (p < .001). Conclusions. Multilevel interventions that focus on individual behavior and community-level targets (e.g., how health care is accessed and delivered) may be needed to improve medication adherence among low-income rural residents.

Intention to use condoms among three low-income urban African American subgroups: cocaine users noncocaine drug users and non-drug users.

Cocaine use, marijuana use, alcohol use, and polysubstance use (e.g., alcohol and cocaine, alcohol and marifuana) are associated with high-risk sexual behavior and higher rates of sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV). The purpose of this study was to examine readiness for using condoms among three groups (cocaine users, noncocaine drug users, and non-drug users) of African Americans living in low-income urban settings. African Americans in this sample differed in sex risk behaviors according to their drug use status. Noncocaine drug users reported higher levels of sex risk behaviors than non-drug users, and cocaine users reported the highest levels of risk. Cocaine users also reported lower levels of condom use with their main and nonmain sexual partners than both other groups. Results of multivariate analyses indicate that, compared to the other two groups, cocaine users are at earlier stages of readiness for condom use with main partners. Cocaine users have accurate perceptions of their HIV risk, but are more likely to factor into their decisions for using condoms cost and the trouble that it takes to get condoms. Different approaches to sexually transmitted disease and human immunodeficiency virus prevention will be necessary to meet the needs of these three different subgroups.

Development and Validation of Instruments to Assess Potential Religion-Health Mechanisms in an African American Population

The health disparities that negatively affect African Americans are well-documented; however, there are also many sociocultural factors that may play a protective role in health outcomes. Religious involvement is noted to be important in the African American community and to have a positive association with health outcomes. However, few studies have explained why this relationship exists. This article reports on the development and validation of instruments to assess two proposed mediators of the relationship between religiosity and health for an African American population: perceived religious influence on health behaviors and illness as punishment from a higher power. We used a systematic iterative process, including interviews and questionnaire data from African Americans who provided feedback on item wording. We also solicited input from African American pastors. In a sample of 55 African Americans, the instruments appeared to have strong internal reliability (α = .74 and .91, respectively) as well as test-retest reliability (r = .65, .84, respectively, p < .001). Evidence for construct validity is also discussed, as are recommendations for health disparities research using these instruments.

Theoretical Approaches Guiding the Development and Implementation of Health Promotion Programs

This chapter describes several theories and models that have been used to explain behavior and to design health promotion and disease prevention programs. Behavioral theories are explanations of what influences people to do the things they do. Behavioral theories generally identify the determinants of behavior, that is, those factors that are thought to be causally related to the behavior. Theories may also identify the mechanisms by which the determinants influence the behavior. Theories are used in several ways to guide the researcher in deciding what research questions are important to ask and to guide the development, implementation, and evaluation of health promotion programs. Theories guide health promotion research by providing propositions about what behavioral factors are related to a health problem and what factors are important to address in working on the problem. For example, smoking is a behavior causally related to many types of cancer. To address smoking and cancer as a public health problem, health researchers and practitioners may ask such questions as: Why do people smoke? What influences people to start smoking? What makes it hard to stop smoking? Why don’t people quit in the face of so much information that it is dangerous? A theory can provide a starting place to look for answers to these questions.

Smoking, sociodemographic determinants, and stress in the Alabama Black Belt.

PURPOSE In the Alabama Black Belt, poverty is high, and the educational level is low. Studies have found increased tobacco use among individuals exposed to high levels of stress. Few studies have been conducted in this region to measure smoking status, its sociodemographic determinants, and how smoking status relates to stressful environmental conditions. METHODS A cross-sectional questionnaire survey of 1,387 individuals. FINDINGS Approximately 25% of the respondents currently smoked cigarettes. Females were less likely to smoke compared to males (OR, 0.29; 95% CI, 0.23-0.38). Blacks were less likely to smoke cigarettes compared to whites (OR, 0.64; 95% CI, 0.43-0.95). Compared to individuals who were employed, participants who were unemployed or retired had increased odds of smoking (OR, 1.68; 95% CI, 1.15-2.20). The odds of being a current smoker were increased in the presence of moderate level stress (OR, 2.06; 95% CI, 1.38-3.07) or when there was a high level of stress (OR, 2.21; 95% CI, 1.47-3.31). Smoking was associated with increased odds of having a moderate level (OR, 2.06; 95% CI, 1.38-3.08) and a high level of stress (OR, 2.21; 95% CI, 1.47-3.32). Females who reported moderate to high levels of stress had increased odds of being smokers compared to males. Interaction between gender and stress showed deviation from additivity. CONCLUSION Our findings suggest a high rate of cigarette use in the area. Increased stress levels appear to predispose females more than males to cigarette smoking. The implications of this association may guide interventions targeted at reducing smoking and its complications.
