Obesity, hope, and health: findings from the HOPE Works community survey.

According to hope theory, hope is defined as goal-directed thinking in which people perceive that they can find routes to desired goals and the motivation to use those routes. The purpose of this study was to explore relationships between hope and body mass index and hope and self-rated health among women completing a community survey conducted in four rural counties in eastern North Carolina. The survey was administered as part of Hope Works, a participatory, community-led intervention program to improve weight, health and hope among low-income women in rural North Carolina. Survey data from 434 women were analyzed. In multivariate models adjusting for age, race, education and income, higher hope was positively related to self-reported health (OR:0.92; 95% CI: 0.89-0.95) and negatively related to BMI (P < 0.01). These results indicated that women who reported better self-rated health also had higher hope scores and women who were heavier had lower hope scores. While these findings are exploratory, they suggest directions for further research. State-based hope is considered to be a characteristic that is malleable and open to development. Future interventions should examine the importance of hope as a construct to examine in weight loss studies. For example, programs could be designed to increase hope by focusing on goal setting and providing support, information and resources to help women work toward their goals.

Development of an instrument to measure glaucoma medication self-efficacy and outcome expectations.

PURPOSE: The purpose of this study was to develop and evaluate the psychometric properties of (a) a glaucoma medication self-efficacy scale and (b) a glaucoma outcome expectations scale. PATIENTS AND METHODS: Two instruments were developed: a glaucoma medication self-efficacy scale and a glaucoma outcome expectations scale. Packets containing (a) the instruments and patient demographic questions and (b) a letter explaining the study were distributed to 225 glaucoma patients from three ophthalmology practices between August and December 2007. The instrument was completed by 191 patients for a response rate of 85%. Principal components factor analysis with a varimax rotation and Cronbach's alpha reliability were used to analyse the data. To assess discriminant validity, we administered the scales and two self-reported measures of adherence in a separate sample of 43 glaucoma patients who were currently using at least one glaucoma medication. RESULTS: Our results yielded a 21-item self-efficacy in overcoming barriers that might interfere with the use of glaucoma medications scale, a 14-item self-efficacy in carrying out specific tasks required to use eye drops correctly scale, and a four-item glaucoma outcome expectations scale. Results of the Cronbach's alpha reliability indicated that the scales are internally consistent. The self-efficacy scales were both significantly associated with two patient self-reported measures of glaucoma medication adherence, which show discriminant validity. CONCLUSIONS: Eye care providers and researchers can use these scales to identify patients with low self-efficacy in using their glaucoma medications and patients who do not believe that following their eye care providers' advice can help their vision.

Patient perceptions about illness self-management in ANCA-associated small vessel vasculitis.

OBJECTIVES: To characterize patient perceptions, related to eight self-management behaviours relevant for adults with ANCA-associated small vessel vasculitis (ANCA-SVV), and to determine if these perceptions were associated with performance of each behaviour. METHODS: Adults with ANCA-SVV (n = 202) completed a self-administered questionnaire that assessed eight self-management behaviours (adherence to recommendations for medication, health service use, diet, exercise, infection avoidance and symptom monitoring; prompt reporting of symptoms and side effects; and adjusting activities in response to symptoms), perceptions about these behaviours, socio-demographics, clinical factors and social desirability bias. Descriptive statistics were generated to characterize patients' perceptions about difficulty of, importance of, and specific barriers to performing each behaviour. Regression analyses explored whether these variables were associated with performing each behaviour, controlling for potential confounders. RESULTS: With few exceptions, higher perceived importance and lower perceived difficulty of each behaviour were associated with more frequent performance of the behaviour. For each behaviour, several specific barriers were frequently endorsed by patients and a number of these were associated with lower levels of self-management. CONCLUSION: This study reveals that patient perceptions about the illness and its treatment influence ANCA-SVV self-management. Perceived barriers to medication, health services, diet and exercise adherence were similar to those in other illnesses. This study also provides insight into barriers experienced by patients in performing behaviours (infection avoidance, symptom monitoring, reporting symptoms and side-effects and adjusting activities) not often previously studied. How the identification of these barriers can help inform future interventions for ANCA-SVV patients is to be discussed.

Genetic testing for colorectal carcinoma susceptibility: focus group responses of individuals with colorectal carcinoma and first-degree relatives.

BACKGROUND: Colorectal carcinoma (CRC) may be the most frequent form of hereditary cancer. Genetic counseling and testing for heritable CRC is a promising approach for reducing the high incidence and mortality rates associated with the disease. Patients with CRC or those with at least one family member with the disease are the most likely persons to request or be offered genetic testing in the clinical or research setting. Currently, however, little is known about the behavioral, psychosocial, ethical, legal, and economic outcomes of CRC genetic counseling and testing. METHODS: Eight focus group interviews, four for CRC patients (n = 28) and four for first-degree relatives (n = 33), were conducted to obtain insights into attitudes, beliefs, and informational needs about genetic testing for hereditary CRC. RESULTS: Focus group interviews revealed a general lack of knowledge about cancer genetics and genetic testing; worry about confidentiality issues; strong concern for family members, particularly children; and a need for primary care providers to be informed about these issues. Major perceived advantages of genetic testing included improving health-related decisions, guiding physicians in making recommendations for surveillance, and informing relatives about risk potential. Disadvantages included potential discrimination, adverse psychologic effects, and financial costs associated with testing. CONCLUSIONS: As knowledge and media coverage of genetics continue to expand, it becomes increasingly important to continue efforts on behalf of, and in partnership with, those individuals most affected by genetic testing for hereditary cancer syndromes. These findings provide data needed to develop and implement informational, educational, counseling, and research-oriented programs that are sensitive to individuals' concerns and preferences.

Tailoring and targeting a worksite health promotion program to address multiple health behaviors among blue-collar women.

PURPOSE: This study examined the relationship between health risks, health behaviors, stages-of-change, and behavior change priorities among blue-collar women participating in a worksite health promotion study. DESIGN: Cross-sectional. SETTING: Rural manufacturing worksites in North Carolina. SUBJECTS: Participants were 859 women aged 18 and over. MEASURES: The self-administered questionnaire assessed smoking, exercise, nutrition (fat, fruits, and vegetables), and breast and cervical cancer screening behaviors. In addition, demographics, body weight, perceived health, stages-of-change, and priority for behavior change were measured. Chi-square tests and regression analysis were used to assess statistical significance. RESULTS: Overall, 28% of women smoked, 37% were completely sedentary, 82% consumed less than five daily servings of fruits and vegetables, and the majority were overweight. The dominant stage of change for each of the lifestyle behaviors was contemplation, whereas most women were in the action stage for cancer screening. When asked to prioritize the behavior they most wanted to change, the majority of women chose healthy eating and/or exercise. CONCLUSIONS: The findings suggest that blue-collar women in this study had multiple health risks and were interested in changing multiple health behaviors. Allowing women to choose the behavior(s) on which they are ready to focus may be a promising approach to tailoring interventions for this population.

Factors affecting African-American participation in AIDS research.

BACKGROUND: Although African Americans are disproportionately affected by the AIDS epidemic, they are underrepresented in AIDS research, particularly in AIDS clinical trials. This study examines a multidimensional construct of distrust and other factors that may affect willingness to participate in AIDS research. METHODS: A total of 301 African Americans (aged >/=18 years) in Durham, North Carolina participated in a cross-sectional survey. In-person interviews, 20 to 25 minutes in length, were conducted with participants. Structural equation modeling was used to develop models exploring distrust and other factors affecting willingness to participate in AIDS research among African Americans. RESULTS: Distrust was the strongest inverse predictor of willingness to participate in AIDS clinical trials. Distrust was not significantly associated with willingness to participate in AIDS surveys and educational interventions. Altruism, facilitators/barriers, religiosity, and economic group membership were also significantly associated with willingness to participate in AIDS clinical trials. Only altruism was significantly associated with willingness to participate in AIDS surveys and educational interventions. CONCLUSIONS: Distrust about research institutions is a significant barrier to recruiting African Americans in AIDS clinical trials. Issues of distrust need to be acknowledged by researchers to develop better recruitment and retention strategies when conducting AIDS clinical trials in African-American communities.

Effects of educational materials concerning osteoporosis on women's knowledge, beliefs, and behavior.

PURPOSE: This study examined the effects of brief written educational materials on osteoporosis-related knowledge, beliefs, and behaviors. The study also examined whether observed effects varied as a function of one's stage in the precaution adoption process. DESIGN: The study used an experimental research design. SETTING: Participants were identified from North Carolina driver's license records. SUBJECTS: Of the 1476 women in the initial sample, 536 (36.3%) enrolled in the study and 307 completed all follow-up assessments. INTERVENTION: Participants were randomly assigned to one of four groups. One group received an information packet containing general information about osteoporosis. One group received an action plan packet containing instructions on how to increase one's level of exercise and calcium intake. One group received both packets. The final group received neither packet. MEASURES: Primary study variables were beliefs related to osteoporosis, calcium, and exercise; osteoporosis knowledge; calcium and exercise stage; calcium intake; and exercise level. RESULTS: Overall, receipt of the information packet was associated with changes in knowledge and beliefs (F[18,283] = 2.11, p < .01) irrespective of participants' stage of change. No effects on behavior were observed. CONCLUSIONS: These findings suggest that brief written educational materials can facilitate knowledge and belief change but that they do not promote behavior change. The generalizability of these findings is limited by the low study response rate.

Interest in genetic testing among first-degree relatives of colorectal cancer patients.

PURPOSE: The present study examined colorectal cancer screening behaviors, risk perceptions, and willingness to receive genetic testing to determine colorectal cancer susceptibility. METHODS: We recruited 95 first-degree relatives of colorectal cancer patients, then conducted a brief telephone interview using a structured questionnaire that elicited information on sociodemographics, cancer screening behaviors, risk perceptions, and interest in genetic testing. RESULTS: Among these high-risk individuals who were aged 40 years or older, only 31% reported fecal occult blood testing within the past year and 59% reported undergoing sigmoidoscopy or colonoscopy within the past 5 years. The majority of participants believed their relative risk of colorectal cancer was increased (68%). Eighty-four percent of the participants indicated that they would have a genetic test if one were available. Participants who believed that <50% of colorectal cancers were caused by heredity were more likely to be interested in genetic testing than were participants who believed that 50% or more of colorectal cancers were caused by heredity. Referral source, sociodemographic factors, clinical factors, and perceived personal risk were not significantly associated with interest in genetic testing. CONCLUSION: Our results suggest that the demand for colorectal cancer susceptibility testing may be high among individuals with a family history of colorectal cancer. We also observed that a substantial number of first-degree relatives were not adhering to colorectal cancer screening guidelines. Accurate information on the genetic aspects of colorectal cancer and the benefits and limitations of genetic testing may help relatives of colorectal cancer patients make informed decisions about whether to undergo enhanced screening and genetic testing.

Adapting a natural (lay) helpers model of change for worksite health promotion for women.

Social network interventions that utilize informal systems of helping can be an important strategy for health promotion change. This article describes the development, implementation and evaluation of a natural (lay) helping intervention for health promotion change, specifically designed for women in small rural blue-collar worksites. One hundred and four women in four intervention worksites were recruited as natural helpers, and received health and skill-building education over an 18-month period. Qualitative evaluation showed: (1) two patterns of natural helping for women, i.e. participation due to a specific health concern with either themselves or others in their personal networks, and participation due to a larger sense of the importance of health and prevention; (2) over time natural helpers expanded the diffusion of health promotion information from close network members to co-workers and were more likely to be approached by their co-workers for information; (3) group activities at the worksite, particularly around physical activity, increased over time; and (4) because of time constraints at the workplace, written materials were a major way of spreading information to co-workers. This study shows that women can be recruited and trained to diffuse health promotion information and provide support to co-workers for health behavior change.

Threat to Parental Role: A Possible Mechanism of Altered Self-Concept Related to Carrier Knowledge.

Researchers and clinicians have suggested that learning one is a carrier for a genetic disorder has the potential to alter self-concept. Concerns about self-concept have influenced the development of policies regarding the availability of carrier testing for minors and the informed-consent process. A literature review identified three mechanisms through which self-concept has been proposed to be affected: altered perception of genetic identity, diminished social identity, and an altered perception of health. This paper presents a conceptual framework developed from identity theory and the "self's response to threat" to propose a fourth mechanism: threat to the parental role. Clarification of the role of self-concept, the threat to self-concept related to carrier knowledge, and coping behaviors activated in response to this threat would help to target appropriate genetic counseling interventions.

Attitudes toward genetic testing in patients with colorectal cancer.

PURPOSE: The purpose of this study was to examine risk perceptions and interest in genetic testing among African American and White patients with colorectal cancer. DESCRIPTION OF STUDY: In this cross-sectional study, 98 patients with colorectal cancer participated in a brief structured telephone interview. Information was collected on knowledge and risk perceptions regarding colorectal cancer genetics, health behaviors, knowledge about the availability of genetic testing, and interest in genetic testing for colorectal cancer susceptibility. RESULTS: Sixty-one percent of the participants were worried about their relatives' risk of colorectal cancer, and 64% were concerned about being a colorectal cancer susceptibility gene carrier. Although 81% of the participants reported that they had never heard about a genetic test for colorectal cancer susceptibility, 72% stated that they would want to take the test if it were available. Predictors of intention to have a genetic test were younger age, less advanced stage of disease, and more frequent thoughts about colorectal cancer being hereditary. CLINICAL IMPLICATIONS: These results suggest that the demand for genetic testing may be great, despite a general lack of knowledge about colorectal cancer genetics and the potential risks and limitations of testing. Education and counseling about cancer genetics and genetic testing may clarify misconceptions about hereditary colorectal cancer and help patients with colorectal cancer and their family members make informed decisions about whether to undergo testing.

Correlates of changes in mood following a mood induction in osteoarthritis patients.

OBJECTIVE: To determine the relationship of mood management skills, and affective and cognitive states to changes in moods following mood induction among people with osteoarthritis. METHODS: After completing questionnaires, participants underwent a negative mood induction. Momentary moods were assessed prior to, immediately following, and several minutes after the mood induction. RESULTS: A specific mood management skill, mood clarity, consistently predicted changes in positive mood following the mood induction: people who scored high on mood clarity experienced less diminution in positive affect. In contrast, changes in negative affect were unrelated to mood management skills. However, people who scored higher on measures of depressive symptoms and pessimism rebounded from the negative induced mood less strongly than others. CONCLUSION: Positive and negative emotional states operate largely independently and are differentially influenced by mood clarity, depressive symptoms, and pessimism. High levels of mood clarity may be adaptive in illnesses such as osteoarthritis because negative affective experiences that may be unavoidable need not preclude positive affective states.

Effect of satisfaction with one's abilities on positive and negative affect among individuals with recently diagnosed rheumatoid arthritis.

OBJECTIVE: The purpose of this study was to examine the effect that self-evaluation processes have on psychologic well-being among individuals with rheumatoid arthritis (RA). METHODS: The study used a longitudinal research design with 4 data collection points. Participants were 227 adults with recently diagnosed RA. Data were collected via mailed questionnaire and telephone interview. Two dimensions of psychologic well-being were assessed--positive affect and negative affect. RESULTS: We found that, among participants who viewed the abilities being evaluated as very important, greater satisfaction at time 1 was associated with less negative affect at time 2 and time 4. Satisfaction was not associated with positive affect at any of the time points, however. CONCLUSION: Study findings indicate that dissatisfaction with illness-related abilities can exacerbate psychologic distress. The findings also highlight the need for research examining the role that positive affect plays in adaptation to RA.

Psychosocial and educational outcomes associated with home- and clinic-based pretest education and cystic fibrosis carrier testing among a population of at-risk relatives.

We report on the psychosocial and knowledge outcomes of two different approaches to cystic fibrosis (CF) gene pretest education and carrier testing offered to 288 proactively recruited first-, second-, and third-degree relatives of people with CF. One group received pretest education and gene testing in a clinical setting from a certified genetic counselor. The other group received pretest education in their homes from a specially prepared pamphlet and were asked to send in a buccal cell sample for genotyping. No statistically significant differences between groups were noted on measures of CF knowledge, anxiety, and positive or negative affect, either while waiting for their test results or within a few weeks after they had learned their results. At both measurement points, participants who had received home education and testing reported that the testing was more convenient, but that they had received less information than they would have liked, and they were more likely to report being confused by the testing, although their level of CF knowledge was comparable to that of people who had been seen by a genetic counselor. In light of the increasing interest in home-based medical testing of all kinds, this study suggests that CF carrier testing in the home warrants further consideration as one possible approach to facilitating access to testing.

Acceptance of home and clinic-based cystic fibrosis carrier education and testing by first, second, and third degree relatives of cystic fibrosis patients.

We contacted and offered free cystic fibrosis (CF) carrier education and testing to the first, second, and third degree relatives of individuals with CF followed at a large Southeastern US CF Clinic. Relatives were offered CF carrier education and testing either in their homes or in a genetic counseling clinic. Overall, of 514 relatives offered free CF carrier education and testing, 299 (58%) accepted. Significantly more (67%) of those offered education and testing in their homes accepted than those offered education and testing in a genetic counseling clinic (45%). Regression analyses identified several factors, including education, income, gender, perceived chance of being a carrier, and perceived chance of having a child who is a CF carrier, as predictors of acceptance of education and testing in both home and clinic sites. A smaller set of factors was identified that predicted acceptance of education and testing unique to each site. Within the limits of this study and its design, even when CF carrier testing is offered free of charge, including education and testing in the home, acceptance of education and testing, while higher than in general population samples, is not universal among at-risk relatives. Several factors which may have contributed to the observations reported in this study are discussed.

Do people with rheumatoid arthritis develop illness-related schemas?

OBJECTIVE: To assess, using both qualitative/inductive and quantitative data, whether people with rheumatoid arthritis (RA) have schemas related to arthritis. METHODS: Themes identified from interview and focus group transcripts were used to develop 1) questionnaire items, and 2) statements participants were asked to recall during home interviews. Two hundred one people with RA completed questionnaires and recall tasks of the type used in cognitive research, followed 10 days later by another recall assessment by telephone. RESULTS: Qualitative methods, item-level questionnaire data, and category-level recall data yielded convergent results supporting 4 final categories: mastery, support, loss of independence, and depression. Regression analyses indicated that category of earlier recollections predicted subsequent recollections assessed via phone. CONCLUSIONS: Results from widely different methods offer at least partial support for arthritis schemas and suggest that the concepts identified are meaningful to patients as well as to researchers.

Date and acquaintance rape. Development and validation of a set of scales.

PIP: Increasing recognition of the prevalence of date/acquaintance rape (DAR) in the US, especially among college women, has led to an understanding that the techniques needed to fend off attacks from friends and acquaintances differ from those used to prevent rape by strangers. This study developed and tested the reliability and validity of the following DAR constructs: perceived vulnerability (underestimation of vulnerability discourages adequate self-protection), self-efficacy, relational priority (neglecting self-interest to save a relationship), rape myth acceptance (subscribing to myths about rape allows women to avoid facing their own vulnerability), and commitment to self-defense. These constructs were also correlated with scales measuring masculinity, self-esteem, and degree of belief in a "just world." Data were gathered to test these constructs via a questionnaire administered to 800 female undergraduate dormitory residents (47% response rate). Analysis of the data allowed refinement of 50 items into 25 items that constitute reliable scales of perceived vulnerability, self-efficacy, and self-determination and a marginally reliable scale of victim-blaming (rape myth). Support was found for 5/6 predicted correlates between DAR scales and 3/5 hypothesized correlations between DAR scales and convergent/discrimination validity scales. Research into this rape prevention tool will continue.^ieng

Proband and parent assistance in identifying relatives for cystic fibrosis carrier testing.

To identify, contact, and offer free cystic fibrosis (CF) carrier education, testing, and genetic counseling to the first, second, and third degree relatives of individuals with CF, study personnel contacted probands or the parents of minor probands requesting assistance in identifying relatives. We requested family pedigrees, including names, addresses, and phone numbers and if necessary a saliva sample for determination of the specific CF mutations in the family. Two hundred three families of 220 probands being followed at a large CF clinic in the Southeastern United States were eligible for inclusion in the study. Of the 203 families 109 (53.7%) assisted by providing contact information on relatives and, when necessary, a saliva sample for mutation analysis. An additional 33 (16.4%) agreed to assist but did not provide either or both contact information or saliva samples. Sixty-one (30.1%) declined to provide assistance. Thirteen percent of the probands/parents wanted to talk with relatives before providing contact information. A logistic regression model predicting proband/parent assistance is provided. This study suggests that the active outreach method used here to identify at risk relatives to offer them CF carrier testing resulted in somewhat lower proband or parent assistance than reported by other similar approaches. The strengths and weaknesses of this approach, including comments by probands and parents on the method, are discussed.

Osteoporosis prevention in premenopausal women: using a stage model approach to examine the predictors of behavior.

The precaution adoption process model was used to examine the predictors of 2 behaviors recommended to reduce the risk of developing osteoporosis: calcium consumption and weight-bearing exercise. A total of 452 premenopausal women completed a mailed questionnaire assessing stage in the precaution adoption process and 12 knowledge and attitudinal variables. Participants were also given an opportunity to request information about osteoporosis. In all, 11 of the 12 knowledge and attitudinal variables were associated with calcium stage; 8 were associated with exercise stage. Information requests were associated with both calcium and exercise stage. Findings provide substantial support for the precaution adoption process model and suggest that the model can be usefully applied in this area to increase understanding of why many women do not practice behaviors that could reduce their risk of developing osteoporosis.
