Varying the Cause of a Challenge to Exercise Identity Behaviour: Reactions of Individuals of Differing Identity Strength

Research shows that people with stronger exercise identity (EXID) exhibit greater negative affect and self-regulatory efficacy (SRE) when behaviour is inconsistent with identity. However, related attributions have not been examined. Using social cognitive and identity theories, we examined causes of failing to exercise. In a two (EXID: stronger, weaker) by two (Cause: personally-controllable, situational) design, participants (N = 224) were randomized to Cause and read a condition-relevant no-exercise vignette. MANOVA revealed main effects for Cause and EXID, p's < .001. Participants explaining their Cause differed on attributional dimensions, and stronger EXID participants reported greater negative affect and higher SRE, p's < .001.
