A missing piece of the transtheoretical model applied to exercise: Development and validation of the temptation to not exercise scale

Building upon previous research examining the Transtheoretical Model (Prochaska & DiClemente, 1986), this paper presents two studies on the development and validation of a Temptation To Not Exercise Scale. Exploratory and confirmatory factor analyses results showed evidence of two factors, labeled Affect and Competing Demands, which had adequate internal consistency scores. Additional validity of the temptation constructs was demonstrated by the significant decrease of the Affect and Competing Demands scores across the stages of change and the negative relationship between self-efficacy and the Affect and Competing Demands scores. The Temptation to Not Exercise Scale may represent a useful component in the application of the Transtheoretical Model to help understand, predict, and explain exercise behavior.
