Purpose. Develop and demonstrate preliminary validation of a brief questionnaire aimed at assessing social cognitive determinants of physical activity (PA) in a college population. Design. Quantitative and observational. Setting. A midsized northeastern university. Subjects. Convenience sample of 827 male and female college students age 18 to 24 years. Measures. International Physical Activity Questionnaire and a PA stage-of-change algorithm. Analysis. A sequential process of survey development, including item generation and data reduction analyses by factor analysis, was followed with the goal of creating a parsimonious questionnaire. Structural equation modeling was used for confirmatory factor analysis and construct validation was confirmed against self-reported PA and stage of change. Validation analyses were replicated in a second, independent sample of 1032 college students. Results. Fifteen items reflecting PA self-regulation, outcome expectations, and personal barriers explained 65% of the questionnaire data and explained 28.6% and 39.5% of the variance in total PA and moderate-to-vigorous–intensity PA, respectively. Scale scores were distinguishable across the stages of change. Findings were similar when the Cognitive Behavioral Physical Activity Questionnaire (CBPAQ) was tested in a similar and independent sample of college students (40%; R2 moderate-to-vigorous–intensity PA = .40; p < .001). Conclusion. The CBPAQ successfully explains and predicts PA behavior in a college population, warranting its incorporation into future studies aiming at understanding and improving on PA behavior in college students.

Purpose. To examine whether residing in a community designed to promote physical activity moderates the relationship between parent perceptions of the neighborhood and general physical activity or active commuting to school in their children. Design. Cross-sectional. Setting. San Bernardino County, California. Subjects. Three hundred sixty-five families (one parent and one child in grades four through eight). Eighty-five reside in a smart growth community designed to be more conducive to physical activity. Measures. Parent perceptions assessed using the Neighborhood Environment Walkability Scale (NEWS). General child physical activity was measured using accelerometers, and active commuting was self-reported by children. Analysis. Two sets of regressions were performed: one for general physical activity, and one for active commuting. Separate models were run in the two sets for each of the 14 NEWS factors, while controlling for demographics. Results. For general physical activity, walking infrastructure, lack of cul-de-sacs, and social interaction had significant main effect associations (p ≤ .05). No factors were moderated by community. The relationships between active commuting to school and perceived crime, traffic hazards, hilliness, physical barriers, cul-de-sac connectivity, aesthetics, and walking infrastructure were significant for those in the smart growth community only (p ≤ .05). Conclusions. Living in an activity-friendly environment is associated with positive relationships between parent perceptions and active commuting behaviors in children. Future interventions should account for both the perceived neighborhood environment and available physical activity infrastructure.

Background: Although wage theft has been discussed primarily as a labor and human rights issue, it can be conceptualized as an issue of structural racism with important consequences for immigrant health.Objectives: The objectives of this study were to: 1) identify sociodemographic, employment, and stress-related characteris­tics that increase LDLs' odds of experiencing wage theft; 2) assess the association be­tween wage theft and serious work-related injury; 3) assess the association between wage theft and three indicators of mental health—depression, social isolation, and alcohol use—as a function of wage theft; and 4) assess serious work-related injury as a function of wage theft controlling for mental health.Methods: Secondary data analyses were based on survey data collected from 331 Latino day laborers between November 2013 and July 2014. Regression analyses were conducted to test the relationships described above.Results: Approximately 25% of participants reported experiencing wage theft and 20% reported serious work-related injury. Wage theft was associated with working in construction and was initially associated with work-related injury. Wage theft was not significantly associated with mental health indicators. The association between wage theft and injury became non-significant when controlling for the mental health variables.Conclusions: The hardship and stress associated with wage theft incidents may ultimately lead to more frequent injury. Al­though we expected an association of wage theft with mental health, we found vulner­ability to physical health as indicated by in­jury incidents. Thus, our basic premise was partially supported: wage theft may act as a stressor that stems from conditions, in part, reflecting structural racism, making work­ers vulnerable to poorer health.Ethn Dis.2021;31(Suppl 1):345-356; doi:10.18865/ed.31.S1.345

Purpose: There is minimal understanding of the potential for coaction, defined as action on one behavior increasing the likelihood of taking action on another behavior, between physical activity (PA) and fruit and vegetable (FV) intake. The purpose of this study was to assess the bidirectional coaction between FV intake and PA, as well as self-efficacy for these behaviors, in a racially diverse sample of obese adults. Design: This is a secondary analysis using data collected from the Path to Health study, a randomized controlled trial. ClinicalTrials.gov Identifier: NCT03674229. Sample: Obese adults who completed baseline and 6-month follow-up assessments. Measures: For this study, data on FV intake, leisure time PA, and 7-day accelerometer data were analyzed at baseline and 6-month follow-up. Analysis: We interchanged modeling the FV intake and PA change variables as the independent and dependent variables. We conducted multiple imputation and both linear and multinomial regression. Results: The sample (n = 168) was 59% female and mainly split between white (42%) and African American (42%). Change in self-efficacy for PA was predictive of change in self-efficacy for FV intake and vice versa. When compared with participants with no change in FV intake, someone with a positive change in FV intake was more likely to have a positive change in self-reported PA (adjusted risk ratio [RR] = 6.72, 95% confidence interval [CI] = 1.69-26.68). Likewise, when compared with no change, participants with a positive change in self-reported PA were more likely to report a positive change in FV intake (adjusted RR = 6.79, 95% CI = 1.70-27.17). Conclusion: Findings suggest coaction between self-efficacy for FV intake and PA as well as between FV intake and PA. Coaction could be capitalized on to more effectively promote both energy-balance behaviors.
