Motivational assessment instruments typically measure clients' attributions about their readiness to change problem behaviors. They do not indicate why a client may be motivated to change, or provide guidance on how to retain an unmotivated client in treatment. The authors interviewed 415 substance abuse clients about their reasons for entering treatment and scored their responses along the dimensions of (a) negative versus positive treatment-entry pressures, (b) internal versus external sources of those pressures, and (c) the life domain from which the pressures emanated. Exploratory cluster analysis yielded 5 types of clients characterized by different profiles of perceived treatment-entry pressures. Cluster membership was predictive of treatment outcomes, and the clusters differed by demographic variables. These data support the discriminative and predictive utility of performing a multidimensional assessment of pressures to enter treatment.
