Abstract

Background and Aims: Previous research indicates that motivational interviewing ( MI ) skills decline over time among participants in training workshops when post‐workshop feedback and coaching are not provided. This study explored moderators of skill retention among trainees learning MI mainly for substance use disorder treatment in real‐world treatment settings, including workshop enhancements and type and dose of post‐workshop feedback and coaching. Methods: A meta‐analysis of training studies was conducted with studies that reported MI skills using observational measures and that included trainees from real‐world agency settings. Standardized change scores were calculated to indicate the magnitude of pre–post training change in MI skills; standardized change scores from post‐training to 3 and 6+ months follow‐up were calculated to indicate the sustainability of training gains over time. Effect sizes were aggregated using random effects models. Results: Twenty‐one papers that reported the effects of MI training on agency staff were included in this review. Across studies, training yielded gains in MI skills ( d = 0.76). Studies that did not include feedback and/or coaching reported eroding skills over a 6‐month follow‐up ( d = −0.30), whereas post‐workshop feedback/coaching sustained skills ( d = 0.03). Effects of post‐workshop feedback/coaching were moderated by frequency, duration and length of training. Moreover, studies reporting low levels of attrition from training protocols showed small increases in skills over the 6‐month follow‐up period ( d = 0.12), whereas studies with high attrition showed skill erosion ( d = −0.29). Conclusions: On average, three to four feedback/coaching sessions over a 6‐month period sustain skills among trainees for motivational interviewing, mainly for substance use disorder treatment. However, high rates of attrition from feedback/coaching contributes to post‐workshop skill erosion.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
