Motivation for addiction treatment-hindi scale: development and factor structure

Area of Science:

• Psychiatry
• Psychology
• Addiction Medicine

Background:

• Motivation is crucial for addiction treatment success.
• Existing generic motivation scales may not be culturally adapted for Hindi-speaking populations.
• Assessing motivation can aid in tailoring treatment strategies for substance use disorders.

Purpose of the Study:

• To develop and validate the Motivation for Addiction Treatment-Hindi (MAT-H) scale.
• To evaluate the scale's reliability and validity in a Hindi-speaking population with alcohol or opioid dependence.
• To explore the scale's utility in differentiating diagnostic groups and predicting treatment outcomes.

Main Methods:

• A 46-item self-report Likert scale (MAT-H) was administered to 262 men diagnosed with alcohol or opioid dependence.
• Factor analysis was employed to identify underlying dimensions of motivation.
• Internal consistency, test-retest reliability, and group differentiation were assessed.

Main Results:

• Factor analysis yielded 15 factors explaining 63.7% of the variance.
• Two primary factors, acceptance and rejection of addiction and treatment, explained 20.7% and 7.6% of the variance, respectively.
• The full scale differentiated alcohol from opioid dependence, while Factors I and II differentiated relapsed from non-relapsed cases.

Conclusions:

• The MAT-H scale is a reliable and valid tool for assessing motivation in Hindi-speaking individuals with substance use disorders.
• The scale's dimensions of acceptance and rejection offer insights into treatment engagement and outcomes.
• The MAT-H scale can be a valuable instrument for clinicians and researchers in addiction treatment settings.
