Examining mindfulness and psychological inflexibility within the framework of Big Five personality

Psychological inflexibility and mindfulness represent two constructs that have garnered a great deal of interest in recent years as central components in the conceptualization of many new cognitive and behavioral therapies. Nonetheless, though theoretically related, relatively little is known regarding associations between these two constructs and consensus models of trait personality such as the Big Five. The current study therefore aimed to more fully elucidate associations among these three domains within a relatively large, diverse undergraduate sample (N = 429). Mindfulness was negatively associated with Neuroticism and positively associated with Conscientiousness while psychological inflexibility was positively associated with Neuroticism and negatively associated with Conscientiousness. Further, while Conscientiousness evidenced the strongest contribution to mindfulness, Neuroticism evidenced the strongest contribution to psychological inflexibility. Better elucidating how psychological inflexibility and mindfulness differentially relate to Big Five personality traits expands the nomological network surrounding these constructs and begins to reveal common processes underlying psychopathology and health behaviors.
