• Registration Number: NCT06670794
• Lead Sponsor: University of Florida

Brief Summary

Aim 1. Couples (N=50 dyads) with a Concerned Partner (CP) and a Drinking Partner (DP) will independently complete baseline and follow-up surveys and a 21-day EMA with three daily reports on their communication and DP's drinking. Aim 2. Iteratively develop a four-session web based intervention and evaluate the WBI's feasibility and acceptability with 15 CPs. Aim 3. Perform a pilot randomized controlled trial (RCT) comparing WBI to psychoeducation control in 110 couples.

Detailed Description

Alcohol misuse negatively affects relationships and is significantly correlated with higher rates of relationship conflict, distress, and dissolution as well as other serious negative interpersonal consequences (e.g., domestic violence, sexual assaults). Encouragement from concerned partners (CPs) is a common motivator for those who misuse alcohol to pursue care and often the most helpful mechanism in supporting change. The goals of this proposal are to: Identify how specific CP behaviors influence their partner's alcohol craving, motives, drinking, and problems on a daily basis using dyadic ecological momentary assessment techniques (Aim 1); use the knowledge from EMA analysis to iteratively develop a CP-focused web-based intervention (WBI) that provides psychoeducation about communication patterns that influence DP drinking and by integrating personalized feedback about CPs' own communication behaviors that may be working against their goals (Aim 2); and pilot the WBI's efficacy on CP outcomes (depression, anxiety, social support), their partner's drinking behavior (alcohol consumption, motives, related consequences), and both partners' relationship distress and conflict (Aim 3). The investigators expect the WBI will yield significant improvements in all outcomes. This project is significant because intervening with CPs has strong potential to change relationship dynamics that may reduce problems and prevent future problems associated with alcohol misuse. It also develops a new prevention model that does not rely on the drinking partner attending a clinical facility to access care. The proposed study is innovative because it uses dyadic and ecological momentary assessment designs to test dynamic questions about interdependence in relationship interactions and alcohol use between partners and employs the generated knowledge to inform intervention adaptation. Teaching CPs to effectively communicate their concerns may be a necessary catalyst for decreasing their partner's alcohol use and preventing alcohol use disorders. The potential reach of this intervention is large such that it can be easily implemented over the web to those who may need help but would not otherwise seek care.

Primary Outcome Measures

Name	Time	Method
DP Alcohol Use Questionnaire	1 month post-intervention.	Drinking Partner's: Alcohol consumption via the Quantity/Frequency/Peak Alcohol Use Index (Dimeff et al., 1991). Six items measure the drinking partner's alcohol consumption. The items are not scored together but evaluated individually (e.g., frequency, typical quantity, peak quantity, etc.). Higher scores denote greater consumption.
CP Depression Symptoms Questionnaire	1 month post-intervention.	Patient Health Questionnaire. 8 items. Scores range from 0-32. Higher scores indicate more depressive symptoms.
CP Anxiety Symptoms Questionnaire	1 month post-intervention.	Generalized Anxiety Disorder scale. 7 items. Higher scores indicate more anxiety symptoms.
CP Anger expression questionnaire	1 month post-intervention.	Dimensions of Anger Reactions - 5 item (DAR-5). Scores range 1-5 with higher scores indicating greater anger.
CP Loneliness Questionnaire	1 month post-intervention.	Measure: UCLA 3-item Loneliness Scale (Hughes, M. E., Waite, L. J., Hawkley, L. C., \& Cacioppo, J. T. (2004). A Short Scale for Measuring Loneliness in Large Surveys. Research on Aging, 26(6), 655-672. https://doi.org/10.1177/0164027504268574) Scores are 1-9. Higher scores indicate more loneliness.
CP Partner Social Support Questionnaire	1 month post-intervention.	Marital Perceived Social Support (Cohen et al., 1985). Scored 0-3. Higher scores mean more social support.
CP-DP Relationship Functioning Questionnaire	1 month post-intervention.	Quality of Marriage Index (Norton, 1983). Higher scores indicate greater relationship satisfaction.
DP AUDIT Questionnaire	1 month post-intervention.	Drinking Partner's AUDIT score. 10 items. Items are summed. Greater scores indicate greater alcohol use.
CP General Social Support Questionnaire	1 month post-intervention.	MOS Social Support Survey (Sherbourne \& Stewart, 1991). Scored 1-5. Higher scores indicate more social support. Sherbourne, C. D., \& Stewart, A. L. (1991). The MOS social support survey. Social science \& medicine, 32(6), 705-714.
DP Drinking Motives Questionnaire	1 month post-intervention.	Drinking Partner's Drinking Motives using the Drinking Motives Questionnaire (Cooper et al., 1992). Subscales for coping, enhancement, social, and conformity. Items are averaged. Higher scores indicate greater endorsement of that motive.
DP Alcohol-related Consequences Questionnaire	1 month post-intervention.	Drinking Partner's Alcohol-related Consequences assess via the Brief Young Adult Alcohol Related Consequences measure. 24 items. Scores are created by summing the items. Higher scores denote greater consequences endorsed.

Subscales include punishing drinking, rewarding sobriety, withdrawing, and supporting drinking. Items are averaged. Higher scores mean greater endorsement of these subscales.
CP-DP Communication: Number of conflicts	1 month post-intervention.	We will ask participants the number of disagreements they have had with their partner. Higher numbers denote more disagreements.
