The boundaries between attachment and personality: Localized versus generalized effects in daily social interaction

A diary study examined the effects of romantic attachment (avoidance, anxiety) and autonomous and sociotropic personality on levels of sociability within social interactions across relational contexts (N = 89 undergraduates). As expected, the effects of domain-specific romantic attachment avoidance and anxiety on sociability were localized to social interactions with romantic partners, whereas the effects of autonomy and sociotropy were generalized across relational contexts (i.e., across social interactions with romantic partners, family members, friends, and acquaintances/others). Furthermore, the effects of both autonomy and sociotropy on sociability were partially mediated by domain-specific attachment in domain-congruent (romantic) but not domain-incongruent (non-romantic) relational contexts: romantic avoidance partially mediated the effects of autonomy on sociability toward romantic partners, whereas romantic anxiety partially mediated the effects of sociotropy. These results suggest that autonomy and sociotropy summarize global regularities in relational responding that correspond to those described by attachment avoidance and anxiety—although (unlike attachment) they do so across relational contexts. Domain-specific attachment representations, in contrast, govern responding within context-congruent domains and act as a mechanism through which personality guides social interaction within these domains.
