Oxytocin and Attachment-related Interpretation Bias

Phase 4
Completed
Conditions
Trust
Interventions
Drug: Placebo
Other: Neutral CBM training
Other: Secure CBM training
Registration Number
NCT02737254
Lead Sponsor
Universitaire Ziekenhuizen KU Leuven
Brief Summary

The purpose of this study is to investigate the effects of oxytocin and a cognitive bias modification (CBM) procedure on children's trust in their mother.

Detailed Description

Previous research has shown that children can be trained to interpret ambiguous interactions with mother in a more secure way by use of a CBM procedure. A secure attachment-related processing bias can causally increase children's trust in mother's availability. The present study tests whether intranasal administration of oxytocin can increase the effect of a secure cognitive bias training. Oxytocin is a neuropeptide that is involved in human attachment and bonding. Intranasal administration of oxytocin can increase trust among people. After oxytocin or placebo administration, children are either trained to interpret ambiguous interactions with mother in a secure way or receive a neutral training unrelated to interpretation of maternal behavior. Pre- and post-intervention children's trust in mother, support seeking behavior and interpretation of maternal behavior is assessed. Moreover, possible oxytocin side-effects will be monitored.

Primary Outcome Measures
NameTimeMethod
Change in trust in motherImmediately before and immediately after intervention

Trust in mother as measured by People in My Life Trust subscale.

Secondary Outcome Measures
NameTimeMethod
Change in attachment-related behavior towards motherImmediately before and immediately after intervention

Observation of the quality of the approach of child towards mother during a puzzle task.

Change in secure interpretation of ambiguous maternal behaviorImmediately before and immediately after intervention

After reading scenarios describing ambiguous maternal behavior, children will be presented with sentences describing secure interpretations of this behavior and are asked to rate on a 4-point Likert scale to what extent this did or did not happen in the scenario. Thereby, children's spontaneous secure interpretation of ambiguous maternal behavior can be assessed.

Change in insecure interpretation of ambiguous maternal behaviorImmediately before and immediately after intervention

After reading scenarios describing ambiguous maternal behavior, children will be presented with sentences describing insecure interpretations of this behavior and are asked to rate on a 4-point Likert scale to what extent this did or did not happen in the scenario, assessing children's spontaneous insecure interpretation of ambiguous maternal behavior.

Interpretation speed of positive maternal behaviorThroughout the CBM training, from around 60 minutes until 110 minutes after the start of the procedure

Reaction times to scenarios describing secure maternal behavior.

Interpretation speed of negative maternal behaviorThroughout the CBM training, from around 60 minutes until 110 minutes after the start of the procedure

Reaction times to scenarios describing insecure maternal behavior.
