Strengthening motivational interviewing skills following initial training: a randomised trial of workplace-based reflective practice.

AIM

The study assesses whether a workplace-based educational intervention helps professionals who had trained in Motivational Interviewing (MI) become more competent in it.

DESIGN

Randomised controlled trial.

PARTICIPANTS

Professionals in health and social services in Dorset, UK, who had received training in MI (n=54).

INTERVENTION

(a)

CONTROL

Update day in MI (b) THEME (Twelve Hours to Enhance Motivational Effectiveness): Update day plus 12 weekly worksheets to stimulate reflection on practice of MI, feedback to audiotaped sessions with clients, and three 30 minute sessions of telephone coaching.

MEASUREMENTS

Degree of competence in MI, as assessed from videotapes of interviews with simulated patients, carried out at entry to the study and 4 months later. Each videotape was coded independently by two trained coders using the Motivational Interviewing Treatment Integrity (MITI) system.

FINDINGS

Of the 44 participants who completed the second assessment, those in THEME showed significantly (p<0.05) greater increases in the Spirit of MI and overall competence in MI.

CONCLUSIONS

Workplace based interventions may enhance the effectiveness of brief training in MI and other psychological therapies.
