Using Ecological Momentary Data to Inform a Web Intervention for Romantic Partners Concerned About Their Loved Ones' Drinking

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.
