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

Motivation for Addiction Treatment-Hindi scale was developed as a 'generic' scale applicable across different substances of abuse. This 46-item self-report Likert scale was administered to 262 treatment-seeking men with a diagnosis of alcohol or opioid dependence as per International Classification of Diseases-10th revision. Factor analysis generated 15 factors that covered all 46 items and explained 63.7% of the total variance. Factors I (12 items) and II (6 items), reflected acceptance and rejection of the existence of the problem of addiction and the treatment offered and, explained 20.7% and 7.6% of the variance respectively. Test-retest reliability and measures of internal consistency yielded satisfactory results. While the whole scale but not Factors I & II differentiated alcohol and opioid dependent groups, Factors I & II but not the whole scale differentiated relapsed from non-relapsed cases at>6 month follow-up. With some limitations, this scale presents a new tool to assess motivation for addiction treatment in Hindi speaking population in terms of two global dimensions of acceptance and rejection of the problem of addiction and the treatment offered.
