Motivational Interviewing
Motivational Interviewing is a humanistic counseling method first described by William R. Miller in 1983 and developed with Stephen Rollnick into its current form. Its core mechanism: resolving ambivalence through evocation of client's own change talk; autonomy support increases intrinsic motivation. This catalogue links it to substance use, eating disorders and child and adolescent behavioral problems, typically in individual format, short-term.

How Motivational Interviewing works
Resolving ambivalence through evocation of client's own change talk; autonomy support increases intrinsic motivation
Ontology
Ambivalence about change is normal; confrontation increases resistance, empathy reduces it
Therapeutic Voice
"So drinking is the one thing that reliably quiets your head at night, and you didn't like who you were on Sunday morning. Where does that leave you?"
View of the Person
An autonomous agent whose ambivalence about change is normal and whose own arguments for change are most powerful

Condition-specific assessments
Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.
Eating Disorders
Population and scope: Community-recruited women with binge-eating disorder receiving an adapted MI session plus self-help; separately, patients awaiting intensive eating-disorder treatment.
Randomized studies
Randomized research supports specific adjunctive uses: Cassin 2008 tested one adapted MI session added to a handbook against handbook alone, with better 16-week binge-eating outcomes. A separate small pretreatment trial studied treatment completion. These findings do not establish stand-alone MI for all eating disorders.

Guidelines and official sources (14)
13 clinical guideline checks · 1 professional reference check
Read the recommendation and its scope. A source may discuss an approach without recommending it.
- Alcohol-use disorders: diagnosis, assessment and management (CG115)
Recommendation for the stated population
NICE recommends an initial motivational intervention incorporating key MI elements. CG115 is alcohol-specific, not a blanket all-substances endorsement.
Scope: People who misuse alcohol, at initial assessment
- Enhancing motivation for change in substance use disorder treatment (TIP 35)
Discussed in the source
TIP35 gives clinical implementation guidance for motivational interviewing. Label it as a SAMHSA treatment manual, not a graded CPG recommendation.
Scope: Substance-use-disorder treatment
- Clinical Practice Guideline for Diagnosis and Treatment of Hypertension in Primary Care
Discussed in the source
VA/DoD names motivational interviewing as a way to deliver lifestyle support. This implementation sidebar does not assign MI a separate evidence grade.
Scope: Lifestyle support alongside home blood-pressure monitoring for hypertension.
- Management of First-Episode Psychosis and Schizophrenia
Insufficient evidence for or against
VA/DoD finds insufficient evidence for or against motivational interviewing for medication adherence in schizophrenia. This conclusion concerns the stated outcome and population.
Scope: Adults with schizophrenia; improving medication adherence.
- Clinical Practice Guideline for the Management of Substance Use Disorders
Discussed in the source
The guideline distinguishes MI from MET, which adds systematic assessment and personalized feedback. Its named MET recommendations should not be read as separate recommendations for every use of MI.
Scope: MI principles within structured motivational enhancement therapy for substance-use disorders.
- Clinical Practice Guideline for Tobacco Use Treatment
Recommendation for the stated population
VA/DoD weakly recommends MI to increase treatment engagement. This recommendation concerns entering treatment, rather than the abstinence effect of MI used alone.
Scope: Adults who use tobacco or nicotine; engagement in cessation treatment.
- Management of Chronic Insomnia Disorder and Obstructive Sleep Apnea
Discussed in the source
The discussion advises a patient-centered motivational interviewing approach to encourage engagement in insomnia treatment. It does not grade MI as a standalone insomnia treatment.
Scope: Encouraging adults reluctant to engage in CBT-I or brief behavioral treatment for insomnia.
- Management of Adult Overweight and Obesity
Discussed in the source
The guideline describes MI techniques for engagement, while noting limited evidence for follow-through with weight-management treatment. This practice guidance is not a separately graded MI recommendation.
Scope: Engagement with recommended weight-management treatment in adults with overweight or obesity.
- Use of Opioids in the Management of Chronic Pain
Discussed in the source
MI appears among non-opioid care options and in tapering studies. The guideline weakly supports collaborative tapering but is neutral on specific tapering strategies; it does not separately grade MI.
Scope: Chronic pain care and collaborative opioid tapering.
- Clinical Practice Guideline for Management of Stroke Rehabilitation
Insufficient evidence for or against
VA/DoD finds insufficient evidence for or against solution-focused psychological interventions, explicitly including MI. This neutral finding concerns prevention, not treatment of established depression.
Scope: Preventing the onset of depression following stroke.
- Clinical Practice Guideline for Psychological and Other Nonpharmacological Treatment of Chronic Musculoskeletal Pain in Adults
Discussed in the source
APA reports insufficient evidence for this comparison. The table groups these approaches without assigning separate protocol grades.
Scope: Knee osteoarthritis; the reviewed CBT/motivational-interviewing/pain-coping-skills category versus usual care.
- Clinical Practice Guideline for Multicomponent Behavioral Treatment of Obesity and Overweight in Children and Adolescents: Current State of the Evidence and Research Needs
Insufficient evidence for or against
APA finds insufficient evidence to prefer MI or other selected components over alternatives. This does not recommend MI alone or address eating-disorder treatment.
Scope: Ages 2–18 with overweight or obesity; MI as one component of a family behavioral program.
- Mental Health Gap Action Programme (mhGAP) guideline for mental, neurological and substance use disorders
Discussed in the source
WHO discusses motivational interviewing findings, but the recommendation names CBT and contingency management. Inclusion in the review is not a separate recommendation for MI.
Scope: Adults with cocaine or stimulant dependence.
- Mental Health Gap Action Programme (mhGAP) guideline for mental, neurological and substance use disorders
Discussed in the source
Motivational interviewing is discussed within the reviewed psychosocial interventions. WHO conditionally recommends structured psychosocial treatment as a group, with low-certainty evidence, while noting uncertainty about individual therapy types versus usual care.
Scope: Adults with alcohol dependence.

Clinical cautions and blind spots
Assessment and precautions
Situations requiring immediate behavioral compliance (e.g., acute medical emergencies), clients already firmly committed to change who need skill-building rather than motivational work, active psychosis impairing capacity for self-reflection
Blind spots
Not a standalone treatment for most conditions; because the method is strategic, its autonomy language can be used instrumentally, steering a client toward an outcome the clinician has already chosen
Philosophical roots
Rogers (empathy, autonomy); Kierkegaard (stages, either/or); Festinger (cognitive dissonance); Deci & Ryan (self-determination theory)
Origins & Influences
Motivational Interviewing emerged from William Miller's experience in 1983 training counselors in Norway. Asked to demonstrate his approach to treating problem drinkers, he realized under their questioning that what he was doing was fundamentally different from the confrontational methods then standard in addiction treatment. Rather than breaking through 'denial' (the dominant model), Miller was rolling with resistance, expressing empathy, and eliciting the client's own arguments for change. What he had been doing, without yet having a name for it, was applying Rogerian principles to a population Rogers himself never focused on. Miller formalized the approach with Stephen Rollnick, drawing on Bem's self-perception theory (the mechanism behind change talk: people work out what they believe partly by hearing themselves say it), Festinger's cognitive dissonance, and Rogers' emphasis on empathy and autonomy. The result was a method that worked precisely because it refused to push: the 'righting reflex' (the therapist's urge to fix) was identified as a reliable way to entrench the very position the therapist is trying to move. MI's spirit (partnership, acceptance, compassion, evocation) is Rogerian through and through, but its technique is more strategic than Rogers would have been comfortable with.
