About

The purpose of this study is to determine the effect of intranasal administration of OT on behavior and discourse of insecure adolescents during a disagreement (stressful situation) with parents.

Full description

Emotional dysregulation and impaired attachment in adolescence are seen by clinical researchers as potential contributors to development of psychopathology. Recent evidence suggests that administration of intranasal OT may facilitate social interaction by attenuating the stress response to interpersonal conflict. However, to date there have been no studies investigating the effects of intranasal OT on parent-adolescent interaction and on neurophysiological emotional strategies in adolescence. To understand these mechanisms, this study examines the effects of OT on interpersonal emotional regulation in adolescent-parent stressful interaction, and on individual visual and physiological strategies in the visualizing attachment-related emotions pictures.

The main objective will be to evaluate the effect of intranasal administration of OT on behavior and discourse of insecure adolescents during a disagreement (stressful situation) with one of his parents.

Secondary is determine the effect of OT on visual exploration strategies and on the physiological responses (heart rate, galvanic skin response) on images elicited attachment-related emotions in insecure adolescents.

In this randomized, double-blind, placebo-controlled, parallel designs, 60 healthy male adolescents classified with an insecure attachment will receive 24 IU of intranasal OT or placebo, 45 min before the experimental tasks. Adolescent will be invited with his/her parent to an experimental conflict discussion. The conflict session will be videotaped and coded for verbal and nonverbal interaction behavior (e.g., eye contact, nonverbal positive/negative behavior, and self-disclosure) with GPACS. Eye tracking and physiological responses will be recorded simultaneously and continuously during pictures viewing.
