Abstract

Restrictiveness, a component of relationship dominance associated with monitoring and regulating partners' behavior, is a risk factor and accelerant of Intimate Partner Violence (IPV). Few studies, however, have examined in vivo physiological responses associated with restrictiveness. Toward this end, 105 romantic couples (N = 210) completed measures of restrictiveness and had their physiological responses recorded in anticipation of and during a dyadic interaction in which they discussed a hypothetical transitional period in which one person (the discloser) revealed to their partner (the responder) that they had just gotten into their dream school or was offered their dream job. Individuals high (vs. low) in restrictiveness exhibited physiological responses indicative of greater psychological challenge (e.g., elevated cardiac output and lower peripheral resistance) in anticipation of and during the conversation. In contrast, their partners exhibited greater physiological indicators of psychological threat in anticipation of (but not during) the conversation, particularly when assigned to the discloser role. Exploratory analyses of communication behaviors corroborated the physiological data. This research integrates the biopsychosocial model of challenge and threat with theories of relationship power and dominance to demonstrate the physiological manifestations of a well-known risk factor for IPV in romantic relationships and interpersonal restrictiveness.
