PRELIMINARY RESULTS OF A NEW INSTRUMENT TO ASSESS PATIENT MOTIVATION FORTREATMENT IN COGNITIVE-BEHAVIOUR THERAPY

Abstract

The Nijmegen Motivation List 2 (NML2) is a new instrument to assess patient motivation for psychotherapy. A previous version of the instrument was associated with positive treatment outcome in cognitive-behaviour therapy in several studies but its psychometric properties were poor. The present study investigated the NML2’s factorial structure, psychometric properties, and predictive value for treatment outcome. The NML2 was completed by 133 outpatients. Three factors were found: preparedness, distress, and doubt. Internal consistencies and re-test reliabilities of the factors were reasonable. The NML2 total score and preparedness were associated with proximal treatment helpfulness and with treatment drop-out. Distress and doubt were not. These findings corroborate those found with the earlier NML version. Rather than assuming that the relationship between motivation factors and treatment outcome is mediated by the amount or quality of treatment or homework compliance, it is proposed that motivation for treatment is the first step in the patient’s change process itself.
