The current study examined the psychometric properties of the Physical Activity and Nutrition Self-Efficacy (PANSE) scale. If proven a valid and reliable measure of self-efficacy for weight-loss behaviors, the PANSE scale may be useful in future research involving activity and nutrition for weight loss. This is particularly important given today’s high prevalence of overweight and obesity, which may be curtailed with increased levels of activity and/or improved food-related behaviors. Initial reliability and validity testing was performed using a sample of 71 women low-income in central Texas. The average age of the participants was 24.5 ± 4.75 years; 35.2% were African American, 32.4% were Hispanic, and 32.4% were White. The women completed the 11-item PANSE questionnaire at baseline and at a 7-week follow-up data collection. Test-retest results provided reliability evidence, and there was sufficient evidence of internal consistency (Cronbach alpha = 0.89). Construct validity was established with significant correlations in expected directions with the Self Care Inventory, Perceived Stress Scale, and Decisional Balance Inventory. The predictive validity of the PANSE scale for weight-loss at 7-week follow-up and program drop out was not established. Exploratory factor analyses revealed a 2-factor model for the 11 items. Initial examination provided evidence for the reliability and construct validity of the PANSE scale. Future testing of the scale should to be conducted with other populations to assess the generalizability of the PANSE scale outside of the population studied in the current report. / text
