Obtaining follow-up interviews for treatment evaluation

Area of Science:

• Addiction research
• Clinical trial methodology
• Public health

Background:

• Substance abuse treatment outcome studies frequently face challenges with subject attrition.
• Follow-up interviews are a primary data source, but locating subjects in the community presents difficulties.
• Effective follow-up methodology is essential for robust research findings.

Observation:

• A comprehensive review of existing literature and practical experience identified 10 essential procedures for successful subject follow-up.
• These procedures were applied in a study involving individuals undergoing methadone maintenance treatment for illicit opioid use.
• High follow-up rates are achievable even for hard-to-reach populations.

Findings:

• The implementation of the 10 identified procedures resulted in an exceptional 98% follow-up interview rate among study participants.
• This demonstrates the practical efficacy of the proposed methodology in maximizing data completeness.
• The study successfully overcame common barriers to subject retention in addiction research.

Implications:

• The 10 recommended follow-up procedures offer a practical framework for researchers to enhance data quality in substance abuse treatment studies.
• Adoption of these methods can lead to more reliable and valid outcome assessments.
• Researchers are encouraged to integrate these strategies to improve the scientific rigor of their follow-up studies.
