The Boredom Prone Personality: A Multitrait-Multimethod Approach

The present investigation reports the convergent and discriminant validity coefficients for two versions of Farmer and Sundberg's (Journal of Personality Assessment, 50(1), 4-17, 1986) boredom proneness scale. Boredom proneness, a trait that refers to an enduring tendency to disengage from the environment, has been neglected by the field of psychology despite its theoretical relevance to performance and psychological well-being. This report sought: (a) to validate a shortened 8-item version of the original Boredom Proneness Scale published by Struk et al. (Assessment, 24(3), 346-359, 2017) and (b) to extensively examine the boredom proneness construct that the long and short versions of this scale assess. We employed a multitrait-multimethod approach that assessed a large number of theorized effects simultaneously. We replicated dozens of theorized and/or previously observed boredom proneness correlates (convergent validity) as well as many theorized null effects (discriminant validity). The overall pattern of significant and null effect sizes provided compelling evidence that the original boredom proneness scale as well as the 8 items that constitute the shorter version are valid measures of one's susceptibility to boredom. We propose that boredom proneness might be an underappreciated yet important theoretical moderator of Person X Situation effects.
