Measuring client perceptions of motivational interviewing: factor analysis of the Client Evaluation of Motivational Interviewing scale
Motivational interviewing (MI) is an intervention approach that has solid evidence of efficacy with substance use disorders. Research and training have benefitted from the development of observational measures to assess MI fidelity and competence. However, one untapped area of assessment is the client perception of the clinician use of MI. Client perceptions of MI have been found through qualitative interviews to relate to motivation to change, view of the therapist and safety of therapy. The Client Evaluation of MI (CEMI) scale was developed to assess client perception of clinician MI use. This study further evaluated the CEMI through exploratory and confirmatory factor analysis with a sample of 500 individuals with dual diagnosis pre-discharge from an inpatient unit. Participants completed an MI based session prior to completing CEMIs. A two factor (relational and technical) model explained 51.1% of the cumulative variance and was supported through confirmatory factor analysis. Suggestions for revisions are provided as well as potential uses of the CEMI and future directions for research. (C) 2013 Elsevier Inc. All rights reserved.
