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.

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.

- Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder
Recommendation for the stated population
PE is one of three specifically named strongly recommended trauma-focused psychotherapies.
Scope: Adults with PTSD
- Post-traumatic stress disorder (NG116)
Recommendation for the stated population
NICE explicitly includes PE among trauma-focused CBT interventions.
Scope: Adults with clinically important PTSD symptoms; timing and diagnosis determine the recommendation
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Recommendation for the stated population
APA strongly recommends PE as a first-line adult PTSD treatment compared with no intervention or treatment as usual.
Scope: Adults with PTSD; comparison with no intervention or treatment as usual
- Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder
Discussed in the source
VA/DoD suggests co-occurring disorders should not preclude these PTSD treatments. This addresses access to treatment, not a separate claim of treating substance use.
Scope: PTSD with co-occurring substance-use disorder or other disorders; therapies named in recommendations 8 and 9.
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Insufficient evidence for or against
APA finds insufficient evidence to prefer PE over those comparators. Its recommendation versus no treatment or usual care does not establish superiority over active therapy.
Scope: Adults with PTSD; PE versus the other active psychological treatments listed in the table.
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Recommendation for the stated population
APA strongly recommends this combination; the table includes PE plus usual care and the COPE protocol.
Scope: Adults with PTSD and co-occurring SUD; PE-based treatment plus usual SUD care versus usual SUD care alone.
- mhGAP evidence profile STR1/STR2: PTSD psychological interventions
Discussed in the source
The WHO evidence review includes PE within individual trauma-focused CBT. The clinical recommendation is for that class, not a separately graded PE recommendation.

PTSD & Acute Trauma
Population and scope: Adults with PTSD receiving individual, manualized Prolonged Exposure (PE). This assessment does not grade all acute post-trauma symptoms, prevention after exposure, childhood PTSD or every adaptation of the protocol.
Guideline recommendation
VA/DoD 2023 recommendation 8 strongly recommends individual, manualized PE for adult PTSD. The American Psychological Association’s 2025 guideline also strongly recommends PE compared with no intervention or usual care (printed p. 7). NICE NG116 (2018) recommendation 1.6.16 names it among individual trauma-focused CBT options after more than one month. These recommendations do not establish that PE is superior to every active psychotherapy or validate the catalogue’s legacy response rates.

How they work
Motivational Interviewing
Core mechanism: 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
Prolonged Exposure
Core mechanism: Repeated imaginal and in-vivo exposure to trauma-related stimuli activates fear structure and provides corrective information
Ontology: Fear structure with pathological associations; avoidance prevents emotional processing

What each assumes — and misses
Motivational Interviewing
Philosophical roots: Rogers (empathy, autonomy); Kierkegaard (stages, either/or); Festinger (cognitive dissonance); Deci & Ryan (self-determination theory)
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
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?
Prolonged Exposure
Philosophical roots: Foa & Kozak (emotional processing theory); Lang (fear structure); Craske (inhibitory learning update); empiricist tradition
Blind spots: Assess practical safety, support and barriers to engagement, and adapt care accordingly. NICE NG116 recommendation 1.7.2 says drug or alcohol misuse alone should not exclude someone with PTSD from treatment. Recommendation 1.7.1 usually prioritizes PTSD treatment when depression co-occurs, but prioritizes depression when its severity prevents PTSD therapy or there is a risk of harm to self or others. Recommendation 1.7.3 calls for support with engagement barriers and attention to safety and stability. The protocol's attention to relational and meaning dimensions remains a clinical consideration, not a finding assessed here.
Therapeutic voice: I want you to close your eyes and tell me what happened, in the present tense, as if it's happening right now.
Choosing between them
Motivational Interviewing (Humanistic) and Prolonged Exposure (Cognitive-Behavioral) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
