Trial Outcomes & Findings for Oxytocin for Couples Conflict Resolution (NCT NCT02941692)

NCT ID: NCT02941692

Last Updated: 2018-10-12

Results Overview

Couples' conflict resolution discussions are video recorded and coded according to an observational coding system: the Rapid Marital Interaction Coding System, which assesses the frequency of behaviors (distress maintaining attributions and relationship enhancing attributions) during the 10 minute conflict resolution discussion. This variable is operationalized as the number of instances of distress maintaining attributions during each of two ten minute conflict resolution discussions.

PRIMARY outcome

Timeframe: Frequency of distress maintaining attrbibutions per 10 minutes

Population: Analyses were limited to heterosexual couples with reliable data reporting in order to accommodate the data analytic approach (i.e., multilevel modeling).

Couples' conflict resolution discussions are video recorded and coded according to an observational coding system: the Rapid Marital Interaction Coding System, which assesses the frequency of behaviors (distress maintaining attributions and relationship enhancing attributions) during the 10 minute conflict resolution discussion. This variable is operationalized as the number of instances of distress maintaining attributions during each of two ten minute conflict resolution discussions.

SECONDARY outcome

Timeframe: Measured at 7 time points: Baseline, immediately before and after Conflict Resolution Task #1, Immediately after Conflict Resolution Task #2, and at 15, 30, and 60 minutes following the completion of Conflict Resolution task #2.

Population: Three couples (6 total participants) were not included in analyses.

Cortisol samples are collected at baseline, pre-post each conflict resolution discussion, and at 15, 30, and 60 minute post-task intervals.
