Area of Science:
- Social Work
- Psychology
- Addiction Medicine
Background:
- Social workers require versatile assessment tools for diverse client needs.
- Existing scales may not adequately address drug abuse and chemical dependency in practice.
- The Index of Drug Involvement (IDI) was developed to fill this gap.
Purpose of the Study:
- To introduce and describe the Index of Drug Involvement (IDI) scale.
- To present initial validation research, including reliability and validity.
- To provide guidance on administration, scoring, interpretation, and clinical application.
Main Methods:
- The study involved the development and initial validation of the IDI scale.
- Reliability was assessed through standard error of measurement.
- Validity was examined across content, construct, and criterion domains.
Main Results:
- The IDI scale demonstrated acceptable reliability and validity.
- Initial research supports its utility for assessing drug involvement.
- A clinical cutting score was developed to aid practitioners.
Conclusions:
- The Index of Drug Involvement (IDI) is a promising tool for social work practice, education, and research.
- It can assist in evaluating the clinical significance of substance abuse.
- The IDI can guide treatment goal setting for individuals with drug abuse issues.
