The Developmental Origins of Personality Factors from the Self-Definitional and Relatedness Domains: A Review of Theory and Research

This paper reviews theory and research on the developmental origins of several widely studied personality vulnerabilities to psychopathology that represent the self-definitional (self-criticism, autonomy, and perfectionism) or relatedness (dependency and sociotropy) domains identified in Blatt's (2008), Blatt and Shichman's (1983), and Beck's (Beck et al., 1983) 2-polarities models of personality. We examine the evidence for the effects of both parenting and peer relationships. We conclude that there is a robust relationship between negative parenting behaviors and the 5 personality vulnerabilities reviewed here which pertain to both self-definition and relatedness, with recent evidence suggesting a possible effect of peer relationships over and above parents. The available evidence suggests that all of the negative developmental experiences studied to date contribute to the development of all the personality vulnerabilities reviewed here. In light of this, we suggest possible mechanisms through which adverse developmental experiences may affect personality factors pertaining to self-definition and relatedness. We also suggest that there may be commonalities across the developmental experiences, such that they result in similar developmental consequences. Although there is now much research on the development of these personality factors, there is still relatively little research examining the roles of factors other than parents and peers, including siblings, romantic partners, environmental changes, and genetics, and we conclude by proposing a revised model of the development of self-definition and relatedness in order to outline future directions for this research field.
