Participants assigned to this arm will attend an in-person weekend retreat where they receive approximately 10 hours of structured curriculum focused on equipping couples with evidence informed strategies to cope with stress as a team, improve emotion regulation, and reduce conflict.

GBT includes modules on emotion awareness, acceptance, reappraisal, constructive problem solving, and communication. The format integrates didactic material, videos, group discussions, and couples' skill practice. All materials and delivery methods have been tailored for military populations based on extensive stakeholder input and field testing.

Couples in the control group will not receive any structured relationship enrichment programming (e.g., retreats or workshops) during the 6-month follow-up period. After the 6-month follow-up period, couples in the control group will be provided access to ePREP, a self-paced on line version of the PREP curriculum.

Get Better Together is a couple-based, primary prevention program designed to reduce risk for suicidal thoughts and behaviors, problematic alcohol use, and intimate partner violence by addressing two transdiagnostic drivers: emotion dysregulation and relationship conflict. The intervention is an adaptation of the empirically supported Prevention and Relationship Enhancement Program (PREP), modified in collaboration with military stakeholders to meet the unique cultural and contextual needs of military couples.

The GBT curriculum includes approximately 10 hours of structured content presented using didactic instruction, video demonstrations, group discussions, and guided couple exercises. Skills focus on interpersonal emotion regulation (e.g., emotion identification, acceptance, reappraisal, and problem solving) and evidence-based communication strategies (e.g., structured communication strategies, conflict de-escalation).

Assessed using the Suicide Cognition Scale-Revised (SCS-R), a 16-item validated self-report measure capturing cognitive risk factors for suicidal behavior. Scores range from 0 to 64, with higher scores reflect greater risk.

Measured using the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), a 3-item measure designed to identify hazardous drinking. Scores range from 0 to 12, with higher scores reflect greater likelihood of drinking affecting one's health and safety.

Measured using the Revised Conflict Tactics Scale-Short Form (CTS2S), a 20-item measure assessing multiple types of relationship abuse. Dichotomous scores will indicate the presence of any form of abuse. Dichotomous subscale scores will indicate the presence of assault, injury, psychological aggression, or sexual coercion.

Measured using the Difficulties in Emotion Regulation Scale - 18 Item (DERS-18), which assesses six dimensions of emotion dysregulation: awareness, clarity, nonacceptance, impulse, goals, and strategies. Total scores range from 18 to 90, with higher scores indicating more severe difficulties regulating one's emotions.

Measured using items adapted from the 2017 Workplace and Equal Opportunity Survey of Active Duty Members (Office of People Analytics, 2018), a DoD standardized survey tool. Items assess key indicators of readiness, including self intent to remain in the military. Items use Likert-type scales appropriate to each domain (e.g., "Very poorly prepared" to "Very well prepared"). The items are designed to be used independently rather than as a single composite scale.
