Measuring affiliation with 12-step groups

Area of Science:

• Addiction Research
• Psychology
• Sociology

Background:

• Assessing 12-step group affiliation is crucial for understanding addiction treatment.
• Existing measures may not fully capture the complexity of group involvement.

Purpose of the Study:

• To evaluate a composite measure of 12-step group affiliation against individual indicators.
• To determine the predictive validity of the composite measure in addiction treatment.

Main Methods:

• Seven measures, including a weighted composite, assessed 12-step group affiliation.
• Participants in a 120-day addiction treatment program completed measures at admission and midpoint.
• Sociodemographic, psychological, satisfaction, and program completion data were collected.

Main Results:

• The composite measure showed stronger relationships with sociodemographic and psychological variables compared to individual indicators.
• The composite measure was more robustly associated with treatment satisfaction.
• The composite measure demonstrated greater predictive power for program completion.

Conclusions:

• A composite measure of 12-step group affiliation offers a more robust assessment than individual indicators.
• This comprehensive approach can enhance understanding of treatment engagement and outcomes.
• Findings have implications for both clinical practice and future addiction research.
