Social Trust and Reciprocity Among Adolescent Girls Exposed to Interpersonal Violence.

Abstract

Trauma research has traditionally focused on altered emotion regulation and its role in psychopathology, whereas mechanisms of social behavior remain comparatively unexplored, particularly among adolescents. It has been previously reported that adolescents with histories of interpersonal violence (IV) demonstrate disrupted social learning, and the degree to which they are impaired during social interactions requiring trustful behaviors may be associated with their levels of anxiety. In the present study, 52 adolescent females (n = 26 control; n = 26 IV-exposed) between ages of 11 and 17 completed a multi-round adaptation of the Trust Game in which they interacted with a confederate peer run by a computer program, alternating between the roles of investor and investee. The task was designed to operationalize the social behaviors of trust and trust reciprocity, where the magnitude of the participants' monetary investment in the confederate during the investor role represented trust while the proportion of investment returned to the confederate in the investee role represented trust reciprocity. IV-exposed and control participants did not differ in trust (i.e., as investors); however, IV-exposed participants without anxiety diagnoses demonstrated lower trust than those with anxiety diagnoses. For trust reciprocity (i.e., as investees), there were again no differences between IV-exposed participants and controls; however, IV-exposed participants with anxiety diagnoses had increased trust reciprocity compared with both other groups. Similarly, caregiver-reported anxiety symptoms were associated with trust reciprocity behaviors among the IV-exposed adolescents. Findings suggest that IV exposure and associated anxiety impacts adolescents' trust behaviors, demonstrating potential mechanisms for maladaptive social behavior among trauma-exposed youth.
