| Abstract: | A scale was adapted from existing scales to measure the outcome expectancy value (EV) as one of contributory factors to leisure-time physical activity (LTPA) and was administered to 649 African American adults. The eligible participants (N = 569) for the analysis were split into three subsamples (rate = 0.5 : 0.25 : 0.25) respectively for Exploratory Factor Analysis (N = 285) and cross-validation (N = 142 for the calibration group and N = 142 for the validation group) to evaluate the psychometric properties of the scale. Item analysis of the scale provided adequate psychometric properties. The 2-factor solution with positive and negative outcome EV subscales was supported based on the exploratory factor analysis and the multiple-group confirmatory factor analysis for both the calibration and validation samples. The results support the factorial construct validity and criterion validity of the outcome EV scale applied to assess LTPA in a sample of church-going African Americans. [ABSTRACT FROM AUTHOR] |
