This transcript of a conference presentation describes a motivational model of alcohol use that shows the interrelationship between the various factors that affect drinking. First, a flow diagram is presented and described that shows how complex biological, psychological, and environmental variables contribute to a person's motivation for drinking, that is, to his or her expectations of affective change from drinking. The variables discussed include past experiences as they shape current expectations, current life situation, and cognitive mediating events such as beliefs, thoughts, and perceptions about the effects of drinking. The rest of the presentation describes the Motivational Structure Questionnaire for Alcoholics (MSQ-A) and discusses how it provides a clinical profile of a patient that can then be used for systematic motivational counseling. Sample clinical profiles are presented in order to illustrate and discuss 10 of the 16 clinical indices revealed by the questionnaire: number of concerns, aversive motivation, lack of commitment, inappropriate commitment, ambivalence, composite emotional intensity, hopelessness, ineffectiveness, goal distance, and alcohol irrelevancy. Paper copies of the slides used in the presentation are included. (TE)
