The WEL was administered to 162 obese patients in a worksite weight management program, and a principal components analysis revealed a 20 item ,five situational factor solution. Cronbach alpha coefficients of internal consistency ranged from a. 90 to .70 .The five factor model was cross-validated using a sample of 220 obese patients at a hospital based weight management program. Structural equation modeling was then used and a five-factor hierarchical model provided the best fit to the data(7).
