Note.iCST = Internet-based Coping Skills Training; DTC = Delayed Treatment Control; SSI = Spouse Situation Inventory; BDI-II = Beck Depression Inventory, Second Edition; STAXI-II = State Trait Anger Expression Inventory, Second Edition; DASS = Depression Anxiety and Stress Scales; AUDIT-C = Alcohol Use Disorders Identification Test consumption items; FHAM = Family History Assessment Module for alcohol dependence; PDA = Percentage of Days Abstinent; DDD = Drinks per Drinking Day; IPV = Intimate Partner Violence (physical). Raw means and SDs are presented; to reduce skew and accommodate outliers, analysis results for some variables are on based on square root (BDI-II, DASS, DDD), negative inverse (STAXI), reflected square root (AUDIT-C), and arcsine (PDA) transformations.
