A prospective test of predictors of physical activity in freshman college women using a path analytic method

Physical activity levels decrease dramatically from childhood to adulthood, and only a minority of adult Americans meets the minimum recommendations for regular exercise. It therefore appears important to intervene with young people to encourage them to continue leading an active lifestyle rather than settling into a sedentary lifestyle common among adults. The first step towards encouraging such activity is to understand the reasons that some individuals adopt an active lifestyle while others do not. The present study examined young adult women entering their first year of college and evaluated the ability of a number of individual psychological variables to predict exercise behavior over several months. The variables explored included those comprising the Theory of Planned Behavior, past exercise behavior patterns, personality characteristics, physical self-efficacy, and change in emotional affect after a single bout of moderate exercise.The participants in this study were asked to walk on a treadmill for 10 minutes (for the purpose of measuring affective change with physical activity), self-report their physical activity over three days, complete a number of questionnaires, and, two to five months later, again self-report their recent exercise behavior. Path analysis was used to evaluate the predictive value of these variables for current and future exercise behavior. Eighty-two women provided data at time 1 and 53 provided data longitudinally. Results indicated that, cross-sectionally, intention and past exercise behavior predicted current exercise behavior most strongly. Longitudinally, in part due to low statistical power, many of these relationships diminished and only current exercise behavior and affect change after walking were independent predictors in the confirmatory model; an exploratory model suggested that personality and intention could also be a significant direct independent predictor of behavior. These differential cross-sectional and longitudinal findings suggest that the women may have been less tuned into internal predilections early in their freshman year, but that these predispositions became more influential later. Past behavior predicted later behavior as expected, but over a limited time span. These findings raise intriguing questions about the changing nature of the early college experience and an individual's changing awareness of environmental versus internal cues for behavior.Ph.D., Clinical Psychology -- Drexel University, 200

Children's physical activity and parents' perception of the neighborhood environment: Neighborhood impact on kids study

Background: Physical activity is important to children’s physical health and well-being. Many factors contribute to children’s physical activity, and the built environment has garnered considerable interest recently, as many young children spend much of their time in and around their immediate neighborhood. Few studies have identified correlates of children’s activity in specific locations. This study examined associations between parent report of their home neighborhood environment and children’s overall and location-specific physical activity. Methods: Parents and children ages 6 to 11 (n=724), living in neighborhoods identified through objective built environment factors as high or low in physical activity environments, were recruited from Seattle and San Diego metropolitan areas, 2007–2009. Parents completed a survey about their child’s activity and perceptions of home neighborhood environmental attributes. Children wore an accelerometer for 7 days. Multivariate regression models explored perceived environment correlates of parent-reported child’s recreational physical activity in their neighborhood, in parks, and in general, as well as accelerometry-based moderate-to-vigorous activity (MVPA) minutes. Results: Parent-reported proximity to play areas correlated positively with both accelerometery MVPA and parent-reported total child physical activity. Lower street connectivity and higher neighborhood aesthetics correlated with higher reported child activity in the neighborhood, while reported safety from crime and walk and cycle facilities correlated positively with reported child activity in public recreation spaces. Conclusions: Different aspects of parent’s perceptions of the neighborhood environment appear to correlate with different aspects of children’s activity. However, prioritizing closer proximity to safe play areas may best improve children’s physical activity and, in turn, reduce their risk of obesity and associated chronic diseases

Smoking, Cardiac Symptoms, and an Emergency Care Visit: A Mixed Methods Exploration of Cognitive and Emotional Reactions

Emergency departments and hospitals are being urged to implement onsite interventions to promote smoking cessation, yet little is known about the theoretical underpinnings of behavior change after a healthcare visit. This observational pilot study evaluated three factors that may predict smoking cessation after an acute health emergency: perceived illness severity, event-related emotions, and causal attribution. Fifty smokers who presented to a hospital because of suspected cardiac symptoms were interviewed, either in the emergency department (ED) or, for those who were admitted, on the cardiac inpatient units. Their data were analyzed using both qualitative and quantitative methodologies to capture the individual, first-hand experience and to evaluate trends over the illness chronology. Reported perceptions of the event during semistructured interview varied widely and related to the individual's intentions regarding smoking cessation. No significant differences were found between those interviewed in the ED versus the inpatient unit. Although the typical profile was characterized by a peak in perceived illness severity and negative emotions at the time the patient presented in the ED, considerable pattern variation occurred. Our results suggest that future studies of eventrelated perceptions and emotional reactions should consider using multi-item and multidimensional assessment methods rated serially over the event chronology

The effect of training in reduced energy density eating and food self-monitoring accuracy on weight loss maintenance

Background: Failure to maintain weight losses in lifestyle change programs continues to be a major problem and warrants investigation of innovative approaches to weight control.Objective: The goal of this study was to compare two novel group interventions, both aimed at improving weight loss maintenance, with a control group.Methods and Procedures: A total of 103 women lost weight on a meal replacement&ndash;supplemented diet and were then randomized to one of three conditions for the 14-week maintenance phase: cognitive-behavioral treatment (CBT); CBT with an enhanced food monitoring accuracy (EFMA) program; or these two interventions plus a reduced energy density eating (REDE) program. Assessments were conducted periodically through an 18-month postintervention. Outcome measures included weight and self-reported dietary intake. Data were analyzed using completers only as well as baseline-carried-forward imputation.Results: Participants lost an average of 7.6 plusminus 2.6 kg during the weight loss phase and 1.8 plusminus 2.3 kg during the maintenance phase. Results do not suggest that the EFMA intervention was successful in improving food monitoring accuracy. The REDE group decreased the energy density (ED) of their diets more so than the other two groups. However, neither the REDE nor the EFMA condition showed any advantage in weight loss maintenance. All groups regained weight between 6- and 18-month follow-ups.Discussion: Although no incremental weight maintenance benefit was observed in the EFMA or EFMA + REDE groups, the improvement in the ED of the REDE group\u27s diet, if shown to be sustainable in future studies, could have weight maintenance benefits.<br /

Where Urban Residents Shop for Produce

There is limited research documenting the shopping behaviors of urban residents with regard to where they shop for fruits and vegetables. This study sought to: (1) describe characteristics of consumers who shop for produce at supermarkets, alternative fresh food outlets, and farmers' markets; and (2) identify correlates of farmers' market shopping among urban consumers. Participants were recruited from 30 randomly selected residential blocks in West and Southwest Philadelphia, Pennsylvania, to complete a cross-sectional survey. Of 622 residents contacted, 82.6 percent completed a usable survey. Participants were predominantly African American (75.2 percent), single (47 percent), and receiving public assistance (30.1 percent). About half of the respondents reported shopping at farmers' markets (48.2 percent), produce stores (47.9 percent), and/or fruit and vegetable trucks (48.0 percent percent) for produce. Having vouchers for farmers' markets was significantly associated with shopping at those markets, being younger, and not owning a car. Our analysis begins to bridge the gap in understanding how individual-level differences may influence shopping patterns. Findings suggest that financial incentives to shop at farmers' markets can be meaningful contributors to shopping at these venues and may work to support the narrowing of disparities in access to healthy, affordable food

Measuring cognitive and affective constructs in the context of an acute health event

The latest recommendations for building dynamic health behavior theories emphasize that cognitions, emotions, and behaviors - and the nature of their inter-relationships - can change over time. This paper describes the development and psychometric validation of four scales created to measure smoking-related causal attributions, perceived illness severity, event-related emotions, and intention to quit smoking among patients experiencing acute cardiac symptoms. After completing qualitative work with a sample of 50 cardiac patients, we administered the scales to 300 patients presenting to the emergency department for cardiac-related symptoms. Factor analyses, alpha coefficients, ANOVAs, and Pearson correlation coefficients were used to establish the scales\u27 reliability and validity. Factor analyses revealed a stable factor structures for each of the four constructs. The scales were internally consistent, with the majority having an alpha of \u3e0.80 (range: 0.57-0.89). Mean differences in ratings of the perceived illness severity and event-related emotions were noted across the three time anchors. Significant increases in intention to quit at the time of enrollment, compared to retrospective ratings of intention to quit before the event, provide preliminary support for the sensitivity of this measure to the motivating impact of the event. Finally, smoking-related causal attributions, perceived illness severity, and event-related emotions correlated in the expected directions with intention to quit smoking, providing preliminary support for construct validity
