title: The video assessment of simulated encounters-revised (VASE-R): reliability and validity of a revised measure of motivational interviewing skills.
abstract: The video assessment of simulated encounters-revised (VASE-R) is a video-based method, administered in individual or group settings, for assessing motivational interviewing (MI) skills. The 18-item instrument includes three video-based vignettes, in which actors portray substance abusers, with each vignette followed by questions that prompt examinees to write responses that are then scored against MI standards. The VASE-R was administered to two independent samples: (1) substance abuse practitioners participating in a study of MI training methods, and (2) MI training facilitators with a high level of MI skill and expertise. This multi-study report describes basic VASE-R psychometric properties -- including scoring reliability, internal consistency, concurrent validity, and sensitivity to the effects of training -- and then presents proficiency standards based on administration to a sample of MI training facilitators (MI Experts). The findings indicate excellent inter-rater reliability using intra-class correlations for the full-scale score (.85) and acceptable levels for subscales (.44 to .73). The instrument displayed strong concurrent validity with the Helpful Responses Questionnaire (HRQ) and a behavioral sample of clinician behavior with a standardized patient scored using the MI Treatment Integrity (MITI) system, as well as good sensitivity to improvement in MI skill as a result of training. The findings provide an empirical basis for suggesting VASE-R benchmarks for beginning proficiency and expert MI practice.
