MITI = Motivational Interviewing Treatment Integrity
MI Adherent Behaviors included those defined by MITI 3.1.1, e.g.., asking permission before giving advice, emphasizing client control, supporting the client with compassionate statements, affirmations
Structured Activities=importance and confidence rulers, change plan, structured feedback, amplified or double-sided reflections, visualization of behavior change
DARN = Desire, ability, reason, need. Note: Because 87/98 (89%) of the sessions did not present readiness utterances, readiness codes from the other 11 patients were excluded from this computation. Scores were averaged over sessions 1 and 2.
Positive M indicates patient bias to change (reduce or abstain from) drinking; negative M indicates patient bias to sustain drinking.
