Applying the resources and supports in self-management framework to examine ophthalmologist-patient communication and glaucoma medication adherence.

Little is known about how ophthalmologist-patient communication over time is associated with glaucoma patient long-term adherence. The purpose of our study was to examine the association between provider use of components of the resources and supports in self-management model when communicating with patients and adherence to glaucoma medications measured electronically over an 8-month period. In this longitudinal prospective cohort study, the main variables studied were ophthalmologist communication-individualized assessment, collaborative goal setting and skills enhancement. Patients with glaucoma who were newly prescribed or on glaucoma medications were recruited from six ophthalmology clinics. Patients' baseline and next follow-up visits were videotape-recorded. Patients were interviewed after their visits. Patients used medication event monitoring systems (MEMS) for 8 months after enrollment into the study, and adherence was measured electronically using MEMS for 240 days after their visits. Two hundred and seventy-nine patients participated. Patient race and regimen complexity were negatively associated with glaucoma medication adherence over an 8-month period. Provider communication behaviors, including providing education and positive reinforcement, can improve patient adherence to glaucoma medications over an 8-month period.

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.

Effect of the women's health initiative on prescription anti-osteoporosis medication utilization.

UNLABELLED: Publication of the Women's Health Initiative (WHI) resulted in a 39% reduction in hormone therapy utilization and a 29% increase in the use of new anti-osteoporosis medications. Overall, the prevalence of prescription anti-osteoporosis medication use declined following the WHI. This has important implications for osteoporosis prevention and treatment. INTRODUCTION: Women who discontinued hormone therapy (HT) following the Women's Health Initiative (WHI) may have been more likely to initiate treatment with newer anti-osteoporosis medications (AOM). The objective of this study was to examine the influence of the WHI on AOM utilization among a nationally representative sample of older adult women in the U.S. METHODS: We used the Medical Expenditure Panel Survey (MEPS) to examine AOM utilization among women aged 50 years and older. National estimates of AOM utilization were predicted from a sample of 2089 women interviewed five times between 2002 and 2003. AOM utilization was dichotomized for HT and newer AOM. Generalized estimating equations were used to predict odds ratios (OR) for AOM utilization controlling for potential predisposing, enabling, and need confounders. RESULTS: Prior to the WHI, there were 8.7 and 3.6 million U.S. women using HT and newer AOM, respectively. One year following publication of the WHI, 5.3 million HT users persisted [OR 0.638 (95% CI: 0.617, 0.756)] while 4.7 million women used newer AOM [1.337 (95% CI: 1.120, 1.597)]. CONCLUSIONS: Although reductions in HT utilization were accompanied by increased utilization of newer AOM, treatment prevalence for osteoporosis remains sub-optimal.

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.

ASHP survey of ambulatory care responsibilities of pharmacists in managed care and integrated health systems--2001.

The results of a 2001 national survey of the ambulatory care responsibilities of pharmacists in managed care organizations (MCOs) and integrated health systems are reported and compared with the results of similar surveys conducted in 1997 and 1999. Three hundred and seventy-six MCOs and integrated health systems participated in the telephone survey. The surveyelicited data about organizational structure and pharmacist functions in the ambulatory care environment. Survey respondents were asked about 24 specific ambulatory care pharmacist functions. The performance of functions was related to five "enabling" factors: pharmacists on interdisciplinary care teams, automated dispensing systems, integrated electronic medical records, very supportive medical staff, and very supportive senior management. Twenty previously measured functions decreased since 1999. Decreases were greatest in negotiating pharmaceutical contracts (-28%), administering immunizations (-27%), and immunization screening (-24%). Enabling factors supported continued expansion. Two clusters of functions, patient-related and population-related activities, were identified and supported differentially by enabling factors. Group-model and staff-model HMOs had the most enabling factors and the broadest scope of pharmacist functions. Independent practice associations had fewer enabling factors and a different mix of functions, with an emphasis on population-focused functions. Ambulatory care functions of pharmacists have expanded to new areas and have decreased in more traditional areas, perhaps because of the current pharmacist shortage and the increase in the number of prescriptions and patients.

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.

ASHP survey of ambulatory care responsibilities of pharmacists in managed care and integrated health systems--1999.

The results of a 1999 national survey of the ambulatory care responsibilities of pharmacists in managed care organizations (MCOs) and integrated health systems are reported and compared with the results of a similar survey conducted in 1997. Four hundred MCOs and integrated health systems participated in the telephone survey. The survey elicited data about organizational structure and pharmacist functions in the ambulatory care environment. Survey recipients were asked about 24 specific ambulatory pharmacist functions. The performance of functions was related to five "enabling" factors: pharmacists on interdisciplinary teams, automated dispensing systems, integrated electronic medical records, and "very supportive" medical staff and senior management. Thirteen functions were reported to be routine activities for more than 50% of the respondents, compared with nine functions in 1997. The top four functions-using pharmacoeconomic data to make formulary decisions, conducting medication management programs, tracking adverse drug reactions, and providing written information with each new prescription-were performed in 75% or more of organizations. Some 15-18% of respondents indicated they would add specialized pharmacy-managed clinics, services to determine patient use of herbal products and dietary supplements, and Internet prescription services within 12 months, suggesting this expansion is likely to continue. Enabling factors supported expansion. Two clusters of functions were identified that related to either population-focused or patient-focused activities, and these were supported differentially by enabling factors. Group-model and staff-model HMOs had the most enabling factors and the greatest scope of pharmacist functions. Independent practice associations had fewer enabling factors and a different mix of pharmacist functions, with an emphasis on population-focused functions, suggesting that a second model of ambulatory care pharmacist activity may be emerging. Ambulatory care functions of pharmacists in integrated health-system settings have expanded broadly since 1997.

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.

Health salience: reclaiming a concept from the lost and found.

This paper describes development of a new measure to assess one dimension of health motivation, the salience of health concerns. The new, five-item, measure was administered to 578 women as part of a larger investigation examining the determinants of exercise and calcium consumption. The study used a cross-sectional survey research design. Data were analyzed separately for premenopausal and menopausal women, allowing us to cross-validate our findings in two independent samples. Our findings suggest that the new measure has many desirable psychometric properties. It is internally consistent (Cronbach's alpha = 0.85 and 0.86 for premenopausal and menopausal women, respectively). For both samples, factor analysis revealed that over 60% of the total item variance was explained by a single underlying factor. All factor loadings exceeded 0.74. The measure also correlated in predictable ways with measures of other health beliefs, differentiated among women in different stages of change with respect to exercise and calcium consumption, and discriminated between women on the basis of their information-seeking behavior. We discuss the potential applications of this new measure in future research. Hopefully, the measure will facilitate research on the role that health salience plays in the behavior change process.

Using a short food frequency questionnaire to estimate dietary calcium consumption: a tool for patient education.

OBJECTIVE: To develop a short food frequency questionnaire (FFQ) assessing calcium intake and a prediction equation for estimating total calcium intake from the short FFQ. METHODS: Data were collected from 536 women via mailed questionnaires at 3 time points. Stepwise regression analyses were used to identify those foods and beverages included in the Black Health Habits and History Questionnaire (HHHQ) that explained the most variance in participants' dietary calcium intake. A prediction equation was developed to estimate total calcium intake based only on information from the foods/beverages identified. RESULTS: Calcium obtained from 15 foods/beverages explained 97.2% of the variance in total calcium intake. The mean absolute difference between total calcium intake estimated from the 15 foods/beverages and the full HHHQ was less than 50 mg at each time point. CONCLUSION: Findings suggest that a short FFQ can provide estimates of total dietary calcium consumption comparable to the full Block HHHQ.

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.

Behavioral and social research in rheumatology.

The recent literature on behavioral and social research in rheumatology covers the descriptive epidemiology of the behavioral, psychologic, and social impact of rheumatic diseases, the identification of risk factors and predictors of psychosocial outcomes, and cognitive and behavioral interventions used in the management of rheumatic disease. Past studies focused primarily on behavioral and social outcomes in rheumatoid arthritis and osteoarthritis. Recent work has continued to explore these issues in rheumatoid arthritis and osteoarthritis, but a number of studies are examining psychosocial impact and interventions in other rheumatic conditions, such as fibromyalgia and systemic sclerosis. The continued understanding of these consequences of rheumatic disease will enhance the quality of life in individuals who have these conditions.

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.

Arthritis and perceptions of quality of life: an examination of positive and negative affect in rheumatoid arthritis patients.

The utility of measuring both positive and negative affective states for assessing rheumatoid arthritis (RA) patients was examined in 3 independent samples of male and female RA patients (Sample A: 179 women, 48 men; Sample B: 177 women, 24 men; Sample C: 134 women, 38 men). Confirmatory factor analyses of each sample indicated that positive and negative affect constituted separate, negatively correlated factors. The relations among disease variables, coping, and affects were consistent with a model in which coping mediates the relationship between disease variables and positive and negative affect. Patients with higher pain and limitation from RA had higher levels of maladaptive coping, and maladaptive coping was associated with lower positive affect and higher negative affect. Those RAs with higher activity limitation also reported less adaptive coping, which was associated with less positive affect.

The relationship between coping and psychological well-being among people with osteoarthritis: a problem-specific approach.

We examined the strategies that people with osteoarthritis (OA) use to cope with illness-related problems in four areas: household activities, leisure activities, pain management, and social relationships. We also examined the relationship between the coping strategies participants reported using upon entry to the study (Time 1) and psychological well-being reported six months later. Three hundred people, aged 50 and over, with OA participated in the study. Data were collected via two mailed questionnaires, administered at six-month intervals. We found that two of the coping strategies examined, self-criticism and social withdrawal, were used more frequently for social relationship problems than for any of the other three types of problems. None of the other coping strategies (i.e. problem solving, cognitive restructuring, social support, emotional expression, problem avoidance, turning to religion, information seeking) were used differentially across problem areas. Multivariate analyses revealed that the coping strategies people used at Time 1 significantly predicted psychological well-being, as assessed by measures of positive affect, negative affect, and depressive symptoms, six months later. However, the specific strategies that predicted positive affect were different from those that predicted negative affect and depressive symptoms. Implications of these findings for future research on coping with chronic illness are discussed.

Psychological distress among survivors of burn injury: the role of outcome expectations and perceptions of importance.

This study examined factors associated with psychologic distress among survivors of burn injury. The study tested hypotheses derived from Scheier and Carver's model of behavioral self-regulation and focused on two primary predictor variables: expectations concerning rehabilitative outcomes and the importance attached to those outcomes. The study used a cross-sectional research design. Two hundred sixteen people who had sustained major or moderate thermal burn injuries within 2 years of study entry served as subjects. Data were collected via mailed questionnaire and chart review. Consistent with study hypotheses, we found that participants who had low expectations for further improvement but who attached high importance to the need for improvement exhibited the most psychologic distress. Study findings lend support to Scheier and Carver's model and suggest that application of this model within the context of burn rehabilitation may increase our understanding of the rehabilitation process. Directions for future theory-based research are discussed.
