Reliability and Validity of the Sedentary Behavior Questionnaire (SBQ) for Adults
Background: Sedentary behavior is related to obesity, but measures of sedentary behaviors are lacking for adults. The purpose of this study was to examine the reliability and validity of the Sedentary Behavior Questionnaire (SBQ) among overweight adults. Methods: Participants were 49 adults for the 2 week test-retest reliability study (67% female, 53% white, mean age = 20) and 401 overweight women (mean age = 41, 61% white) and 441 overweight men…
Do neighborhood environments moderate the effect of physical activity lifestyle interventions in adults
Latent Growth Curve Modeling of Adolescent Physical Activity
Data from a randomized clinical trial were used to examine the extent to which a health promotion intervention affected changes in psychosocial constructs and if so whether these in turn explained changes in physical activity (PA). PA and psychosocial data on 878 adolescents (ages 11-15) recruited through primary care providers (age M = 12.7 years, SD = 1.3; 58% white non-Hispanic) were measured at baseline, six and 12 months. Parallel process la…
Psychosocial Correlates of Dietary Intake Among Overweight and Obese Men
Community Design and Access to Recreational Facilities as Correlates of Adolescent Physical Activity and Body-Mass Index
Background: Neighborhood-level environmental features have been associated with adult physical activity and weight status, but this link has not been established for adolescents. Methods: Community design and access to recreational facilities variables were derived using geographic information systems (GIS) for 799 adolescents (age 11 to 15 y, mean = 12.8 y, 53% girls, 43% ethnic minority). Environment variables were calculated for a 1-mile buffe…
Effect of a Tailored Physical Activity Intervention Delivered in General Practice Settings
Objectives. We evaluated the effectiveness of a minimal intervention physical activity strategy (physician-based assessment and counseling for exercise [PACE]) applied in general practice settings in the Netherlands. Methods. Randomization took place at the general practice level. Participants were patients aged 18–70 years of age who had been diagnosed with hypertension, hypercholesterolemia, or non–insulin-dependent diabetes and had not been re…
Assessing Perceived Physical Environmental Variables that May Influence Physical Activity
The present study evaluated a measure of perceived physical environments that may influence physical activity. Forty-three self-report items were used to assess environmental variables at homes, in neighborhoods, or on frequently traveled routes. The presence of facilitators of (e.g., equipment, programs, attractive surroundings) and barriers to (e.g., high crime) physical activity was assessed. In 110 college students, test-retest reliabilities …
