Psychometric Testing: Self-Efficacy for Calorie Control and Exercise

Enhancing self-efficacy for calorie control and exercise is a crucial strategy for successful weight management. This study developed and psychometrically tested a 13-item quick checklist for assessing self-efficacy for calorie control and exercise (QCSE-CCE). A convenience sample of 425 adults between 18 and 69 years old completed the QCSE-CCE online. The principle axis factor analysis and a parallel analysis demonstrated a three-factor structure that accounts for 72.8% of the total variance. The confirmatory factor analysis indicated a good model fit (χ²/df = 2.168, GFI =.913, AGFI =.873, RMR =.049, RMSEA =.073, CFI =.959). The predictive validity was adequate (.38 < r <.39, p <.000), with Cronbach’s alphas ranging from.87 to.91. The test-retest demonstrated good stability (r =.69; p <.001). The QCSE-CCE is a valid and reliable instrument for assessing self-efficacy for calorie control and exercise for weight management purposes.
