Knowledge of motivational interviewing.

摘要

PURPOSE: The overall goal of this pilot study was to determine the effects of a motivational interviewing (MI) educational program on MI knowledge. DESIGN: Pretest/posttest intervention study. METHOD: Eleven participants completed a 20-item test prior to a 6-hour course on motivational interviewing. Six of those participants completed a second 2-hour educational session and a posttest. FINDINGS: On average, participants increased their score from the pretest (mean [M] = 12.7, range 8-16; standard error [SE] = 1.256) to the posttest (M = 15.5, range 14-17; SE = 0.428). Although, this difference was not significant, t(5) = -2.49; p = .055; r = .55, given a standard level of significance of .5, the effect size was large, representing a substantive change. CONCLUSIONS: The motivational interviewing intervention was deemed clinically successful by the multidisciplinary committee based on the large effect size.
