# Motivational Interviewing in Addiction Psychiatry

## Overview and Origins

Developed by William R. Miller (1983) and refined with Stephen Rollnick. Originally developed for alcohol use disorders; now applied broadly across substance use, psychiatric, and medical conditions. Defined as "a collaborative, goal-oriented style of communication with particular attention to the language of change, designed to strengthen personal motivation for and commitment to a specific goal by eliciting and exploring the person's own reasons for change within an atmosphere of acceptance and compassion". MI is a clinical style, not a specific technique -- it can be integrated into any clinical encounter.

## The Spirit of MI

Four interrelated elements that define the practitioner's mindset:

### Partnership

MI is done WITH the person, not TO them. The clinician is not the expert on the patient's life -- the patient is. Avoids the "expert trap" of telling patients what to do.

### Acceptance

Four components: absolute worth (unconditional positive regard), accurate empathy, autonomy support, affirmation. The clinician honors the patient's inherent worth and right to self-determination. Acceptance does NOT mean approval of harmful behavior.

### Compassion

Active promotion of the patient's welfare; prioritizing the patient's needs. Distinct from sympathy or pity.

### Evocation

The patient already has the reasons for change within them -- the clinician's role is to draw them out. Contrasts with the "information deficit" model (assuming the patient just needs more education)

## Core Techniques: OARS

### Open-Ended Questions

Invite the patient to elaborate and reflect. Examples: "What concerns you most about your drinking?" "How would your life be different if you made this change?" "What are the good things about using?". Avoid closed questions that can be answered with yes/no.

### Affirmations

Statements that recognize the patient's strengths, efforts, and values. Not the same as praise (which implies a power differential) Examples: "It took courage to come in today." "You clearly care a lot about your family.". Focus on character strengths, not specific behaviors.

### Reflections

The most important and frequently used MI skill. Simple reflection: repeats or rephrases what the patient said. Complex reflection: adds meaning, feeling, or emphasis; reflects the unspoken. Amplified reflection: slightly overstates the status quo to evoke the patient's own counterargument. Double-sided reflection: captures both sides of ambivalence ("On one hand you enjoy drinking with friends, and on the other hand you're worried about losing your job") Aim for reflection-to-question ratio of 2:1 or higher.

### Summaries

Collect and link what the patient has said; demonstrate that you have been listening. Transition summaries: used to shift focus or close a topic. Strategic: emphasize change talk that the patient has expressed.

## Change Talk and Sustain Talk

### Change Talk (Language Favoring Change)

**Preparatory change talk (DARN):**. **D**esire: "I want to cut down". **A**bility: "I think I could stop if I tried". **R**easons: "My health is suffering". **N**eed: "I have to do something about this". **Mobilizing change talk (CAT):**. **C**ommitment: "I will stop drinking". **A**ctivation: "I'm ready to try". **T**aking steps: "I poured out the bottle yesterday". Mobilizing change talk is the strongest predictor of behavior change. The clinician's task: elicit, recognize, and reinforce change talk.

### Sustain Talk (Language Against Change)

Arguments for maintaining the status quo: "I don't think I have a problem," "Drinking helps me relax," "I can't imagine socializing without it". NOT resistance -- it is a natural part of ambivalence. Respond with empathy and reflection, not confrontation. Avoid the "righting reflex" (the urge to correct, argue, or persuade)

### Discord

Replaces the older concept of "resistance". Signals a problem in the therapeutic relationship, not in the patient. When discord arises: reflect, adjust your approach, emphasize autonomy. "If you're arguing for change and the patient is arguing against it, you're doing it wrong".

## Stages of Change (Transtheoretical Model)

### Integration with MI

Prochaska and DiClemente's model describes stages: precontemplation, contemplation, preparation, action, maintenance, (relapse) MI is particularly effective in the precontemplation and contemplation stages (ambivalent patients) The model is descriptive, not prescriptive; patients do not move linearly through stages.

### Matching MI to Stage

**Precontemplation:** build rapport, raise awareness, avoid pushing; the patient is not yet considering change. **Contemplation:** explore ambivalence (decisional balance), elicit change talk, develop discrepancy between current behavior and values. **Preparation:** support self-efficacy, help formulate a plan, strengthen commitment. **Action/Maintenance:** support ongoing change efforts, plan for high-risk situations, normalize setbacks.

## Developing Discrepancy

A core MI strategy: help the patient see the gap between their current behavior and their deeply held values or goals. NOT imposed by the clinician -- evoked through reflective listening and strategic questioning. Example: "You've said your children are the most important thing in your life. How does your drinking fit with being the parent you want to be?". When the patient articulates the discrepancy, it is far more powerful than when the clinician points it out.

## Evidence Base

### Substance Use Disorders

Over 200 RCTs supporting MI across substance use disorders. Effect sizes: small to moderate (d = 0.25-0.50) but consistent. Most effective as a brief intervention (1-4 sessions) Enhances engagement in subsequent treatment when used as a prelude to other therapies (CBT, 12-step) Effective for alcohol, cannabis, tobacco; less studied for opioids and stimulants as standalone treatment.

### Other Psychiatric Applications

Treatment adherence in schizophrenia (medication compliance, engagement with services) Dual diagnosis populations (co-occurring SUD and mental illness) Lifestyle modification (weight management, physical activity, diabetes management) Medication adherence in depression and anxiety.

### Limitations

Not designed as a standalone treatment for severe addiction -- best as a brief intervention or prelude. Requires significant training and ongoing supervision to develop competence. Fidelity to MI principles is essential -- "MI-inconsistent" behaviors (confronting, directing, warning) worsen outcomes.

## MI in Psychiatric Assessment

Every psychiatric interview is an opportunity for MI. Incorporating OARS into the initial assessment can improve therapeutic alliance and treatment engagement. Particularly valuable when patients are ambivalent about medication, hospitalization, or behavioral change. "Rolling with resistance" prevents ruptures in early clinical relationships.

For each element, include a brief definition and a clinical example. Surround the circle with the four OARS techniques (Open questions, Affirmations, Reflections, Summaries) as practical tools that express the spirit. Show how the spirit guides the use of techniques, not vice versa. Clinical education style.

(Reflect empathically, explore, avoid arguing.) Is it discord? (Reflect, adjust approach, emphasize autonomy, apologize if needed.) Include examples at each branch. Show the "righting reflex" as a common clinician error to avoid. Clinical training format.

## Clinical Pearls

MI is a way of being with patients, not a set of tricks -- the spirit (partnership, acceptance, compassion, evocation) matters more than the techniques. The righting reflex (the clinician's urge to fix, correct, or persuade) is the most common MI error -- when you find yourself arguing for change and the patient arguing against it, reverse course. Reflections should outnumber questions by at least 2:1 -- most clinicians ask too many questions and do not reflect enough. Change talk predicts behavior change -- learn to recognize it, elicit it, and reinforce it; do not let it pass unremarked. Discord is a signal about the relationship, not the patient -- if a patient becomes argumentative, the clinician should adjust their approach rather than escalating. MI is most effective as a brief intervention (1-4 sessions) or as a prelude to more intensive treatment -- it is not designed as a long-term standalone therapy for severe addiction. Every psychiatric assessment can incorporate MI principles -- open-ended questions, reflections, and affirmations improve engagement regardless of the clinical context.
