Oxytocin for Couples Conflict Resolution

September 14, 2018 updated by: Medical University of South Carolina

The Effects of Oxytocin on Couples Conflict Resolution Interactions

Oxytocin is a promising new medication found to have positive effects on prosocial behavior, reduce negative affect such as fear and anxiety, and reduce stress-induced addictive behaviors. This study aims to investigate the extent to which a 40 IU dose of intranasal oxytocin improves couples' conflict resolution skills and subjective, physiological, and neuroendocrine responses to conflict. Conflict resolution discussions will take place in the laboratory and will be videotaped.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Substance use disorders (SUD) are characterized by dysregulation of the hypothalamic-pituitary axis (HPA). The neuropeptide oxytocin, commonly administered as an intranasal spray, is a drug that has prominent anxiolytic and prosocial effects on human behaviors. While the mechanisms of action facilitating the behavioral effects of oxytocin in humans is complex and many questions about this process remain, there is a consensus in the existing literature that oxytocin modulates HPA axis reactivity to stressful social stimuli. Preliminary studies suggest that oxytocin is known to reduce couple conflict among normative couples. A more developed line of research indicates that oxytocin mitigates addictive behaviors in the context of various drugs of abuse. Given the high prevalence and severity of dyadic conflict among couples where one or both partner has substance abuse, and given the salience of dyadic conflict as a precipitant to substance use behaviors, it is critical to investigate the therapeutic effects of oxytocin among couples with substance use problems. Namely, oxytocin holds promise as a potential augmenter for conjoint couples therapies, particularly those targeting the reduction of substance use problems. However, only two studies have examined the effects of oxytocin on couples' communication behaviors. Those two studies found that couples' communication skills improved following the administration of oxytocin. It is important to extend this line of research to examine conflict resolution skills among couples with substance use problems. To date, no studies have examined the effects of oxytocin on subjective, physiological, or neuroendocrine reactivity to dyadic conflict. The present study aims to fill that gap in the literature.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Frequency of Distress Maintaining Attributions
Time Frame: Frequency of distress maintaining attrbibutions per 10 minutes
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.
Frequency of distress maintaining attrbibutions per 10 minutes

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Salivary Cortisol (μg/dL)
Time Frame: 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.
Cortisol samples are collected at baseline, pre-post each conflict resolution discussion, and at 15, 30, and 60 minute post-task intervals.
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.
