The Motivational Structure Questionnaire (MSQ) identifies problem drinkers' maladaptive motivational patterns that underlie their motivations for drinking alcohol. It does so by having respondents name their current concerns in major life areas and characterize each concern along dimensions that reveal the structure of their motivation. A computer program then generates quantitative indices and a motivational profile depicting the respondent's significant motivational features and problem areas. Administration takes 2-3 hours on average. The MSQ can help pinpoint problem drinkers' motivational issues to provide a basis for motivational counseling to change maladaptive patterns. It has been used in research concerned with motivational and volitional factors.
