Personality and Lifetime Need Frustration: A Person-Centered Perspective on Interpersonal Problems and Personality Pathology

The current research adopted a person-centered approach to examine whether people’s experiences of lifetime need frustration interact with their personality trait profiles to predict their problems and pathology from the perspectives of both the interpersonal circumplex (IPC) and the five-factor model (FFM). Data ( N = 1,026) were analyzed using multilevel modeling. Consistent with prediction, lifetime need frustration predicted participants’ overall levels of interpersonal distress and personality pathology. Furthermore, levels of lifetime need frustration predicted the strength of the relationship between participants’ trait profiles (i.e., IPC and FFM) and their corresponding profiles of interpersonal problems and personality pathology. Findings from the present study demonstrate how between-person differences in lifetime need frustration give rise to the within-person organization of psychological maladjustment and highlight the importance of people’s traits in predicting their unique maladaptations to having their basic psychological needs frustrated.
