Evidence that specific personal relationships evoke maladaptive personality expression

INTRODUCTION

This research applied relational regulation theory (RRT) to maladaptive personality as identified in the DSM-5, dimension trait model. RRT describes how individual social network members help people regulate their own affect, thought and action. Previous research found that people expressed different levels of normal personality dimensions and affect depending upon the network members that people were with or thinking about.

METHODS

College students (N = 719) rated their expression of maladaptive dimensions and affect when with important network members, as well as the interpersonal characteristics of network members.

RESULTS

People's maladaptive personality expression was strongly consistent across network members (recipient effects). Yet, personality expression also varied strongly depending upon which network member the recipient was with or thinking about (dyadic effects). PID-5 negative affectivity and PANAS negative affect more strongly reflected dyads than recipients. Antagonism and disinhibition more strongly reflected recipients than dyads. Network members who evoked maladaptive expressions were seen by recipients as unsupportive, unresponsive, as evoking conflict, attachment avoidance and attachment anxiety. However, the interpersonal constructs were mostly redundant in predicting maladaptive personality. Findings were replicated across random subsamples and gender.

CONCLUSION

The findings provide evidence that important personal relationships can evoke the expression of maladaptive personality.

The relational regulation of within-person variation in personality expression

There is renewed interest in how people express different levels of personality across situations or times (within-person variation). However, within-person studies typically do not focus on the specific relationship partners that are linked to the expression of personality. To remedy this, we applied relational regulation theory (RRT) to the study of within-person variation. RRT states that specific relationship partners are important social contexts for understanding within-person variation and describes how people regulate their affect, action and thought through interacting with or thinking about specific partners. In three studies of students (Ns = 136, 349, 110), participants rated their levels of six- or five-factor personality dimensions when with or thinking about different relationship partners. Personality expression was strongly consistent across partners. Yet, in each study, there were also strong effects whereby more extraversion, agreeableness and openness were expressed when with some partners but not others. In each study, when a recipient saw a relationship as supportive, the recipient expressed more extraversion, agreeableness, and openness. Effects for emotionality and conscientiousness were less consistent. Theoretical implications for RRT and within-person variation in personality were discussed.
