The purpose of this study was to determine whether the availability and accessibility of physical activity resources differed by neighborhood socioeconomic status (SES) in a small U.S. city (population = 133,046). U.S. census tracts (N =32) were used to represent neighborhoods and categorized into high, medium, or low SES on the basis of the percentage of unemployed individuals, per capita income, and percentage of the population below the poverty threshold. We developed a geographic information system to generate a comprehensive list of physical activity resources available within each census tract in the city. We identified 112 parks, 33 sport facilities, 15 fitness clubs, 11 community centers, and 5 walking/biking trails. The total number of physical activity resources varied by neighborhood SES (p <.05); low-SES (M =4.5-/+2.3) and medium-SES (M =4.9-/+2.6) neighborhoods had significantly fewer resources than high-SES (M =8.4-/+3.5) neighborhoods. Low-, medium-, and high-SES neighborhoods did not differ on the number of pay-for-use facilities; however, low-SES (M =3.1-/+1.5) and medium-SES (M =3.8-/+1.6) neighborhoods had significantly fewer free-for-use resources than high- (M =6.1-/+2.4) SES neighborhoods (p <.01). Data suggest that individuals from lower SES neighborhoods may have limited ability to control their physical activity in the face of inaccessible environments. Community research and promotion efforts should include assessment and targeting of available and accessible physical activity resources.

Objective. To examine whether the theory-based social cognitions of perceived barrier frequency, barrier limitation, and self-regulatory efficacy to cope were predictors of planned physical activity among adult women with arthritis. A secondary purpose was to identify and provide a phenomenologic description of the relevant barriers and coping strategies reported by study participants. Methods. Eighty adult women (mean ؎ SD age 49.09 ؎ 12.89 years) with self-reported doctor-diagnosed arthritis participated in this observational study. Participants completed online survey measures of barriers to physical activity and, for each barrier, reported the frequency of occurrence and the extent of limitation. Measures of coping strategies for each barrier, efficacy to cope, and physical activity were also obtained. Results. A multiple hierarchical regression analysis resulted in a model that significantly predicted physical activity (F[9,70] ‫؍‬ 6.80, P < 0.01, adjusted R 2 ‫؍‬ 0.40). Barrier limitation (standardized ␤ ‫؍‬ ؊0.56) and efficacy (standardized ␤ ‫؍‬ 0.20) were significant independent predictors. Phenomenologic findings indicated that arthritis-specific personal barriers (e.g., pain and fatigue due to arthritis) and arthritis-specific coping strategies (e.g., activity modification) were more commonly reported than generic barriers and coping strategies. Conclusion. Self-regulatory efficacy to cope and relevant perceived physical activity barriers, which were primarily arthritis-specific and moderately or more limiting to planned physical activity, were important social cognitive predictors of physical activity, a key nonpharmacologic arthritis treatment, among women with arthritis. Future research direction should examine potential moderators of the relationship between these predictors and physical activity, such as pain acceptance.

The purpose of the study was to examine the relationship between perceptions of self-efficacy, proxy efficacy, and exercise class attendance of participants involved in a 10-week structured group fitness program. At week 3, 127 females completed measures of self-efficacy and proxy efficacy and their class attendance was monitored for the subsequent four weeks. Self-efficacy was assessed through measures of exercise, scheduling, and barrier self-efficacy. Proxy efficacy was assessed through a measure of fitness instructor efficacy defined as participants' confidence in their fitness instructors' communication, teaching, and motivating capabilities. Results revealed positive correlations between self-efficacy variables and proxy efficacy. Hierarchical multiple regression analyses indicated that among those who were classified as exercise initiates (n = 33), self-efficacy and proxy efficacy accounted for 34 percent of the variance in exercise class attendance with the latter variable explaining a unique 12 percent. Consistent with theorizing, these preliminary findings indicate that for instructor-led, group physical activities such as aerobics classes, proxy efficacy perceptions are related to self-efficacy and may also be an important predictor of exercise behavior.

Pain from arthritis is a barrier to physical activity (PA), yet some people still manage to be active. This study examined whether women with greater or weaker arthritis pain acceptance were distinguished by social cognitions (self-regulatory efficacy to overcome barriers; outcome expectations of PA) and whether PA differences existed. Women with arthritis (N = 118) completed two surveys. After controlling for pain, a hierarchical discriminant function analysis discriminated pain acceptance groups in terms of the social cognitions. Greater pain acceptance participants were also significantly more active. Findings contribute new insight on the combination of a disease-related factor (pain acceptance) and social cognitions important for adherence.

The purpose was to examine if the acute thoughts that individuals have as a function of deciding whether to exercise influence subsequent motivated behavior. Two questions based on self‐efficacy theory were tested. Are immediate, retrospective, or anticipated thoughts predictive of self‐efficacy to adhere to regular exercise? Does self‐efficacy influence exercise intention and behavior? Participants were 82 healthy adults (M age = 24 years) enrolled in a 10‐week exercise program. Social cognitive measures were assessed after 1.5 months of experience, and 3 weeks of exercise were tracked. Multivariate analyses showed that participants who were more positive in their acute retrospective or anticipated thinking exhibited significantly higher self‐efficacy and attendance than did negative‐thinking counterparts. Multiple regression analyses revealed that acute retrospective and anticipated thoughts were predictors of self‐efficacy. In addition, self‐efficacy was predictive of future intention and exercise attendance.
