What this trial studies

This study evaluates the effectiveness of the Fathers for Change (F4C) program compared to Individual Drug Counseling (IDC) in a randomized controlled trial involving 280 fathers undergoing substance use treatment. The trial aims to reduce substance misuse and family violence at the end of treatment and during follow-ups at 3 and 6 months. It also seeks to document improvements in emotion regulation as a mechanism for the observed reductions in substance use and family violence. Participants will be recruited from community and veterans healthcare settings.

Who should consider this trial

Good fit: Ideal candidates are fathers with a substance use disorder who have reported family violence within the last 18 months and have at least one biological child aged 1 to 12 years.

Not a fit: Patients with active protective orders, severe substance addiction requiring detoxification, or untreated severe mental health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatment options for fathers struggling with substance misuse and family violence, ultimately improving family dynamics and child well-being.

How similar studies have performed: Other studies have shown promise in similar interventions targeting substance misuse and family violence, suggesting potential for success in this approach.
