Programme Summary
Programme Summary: Motivational Interviewing (MI) for Substance Use Disorders
Motivational Interviewing (MI) is a person-centred, counselling approach used to address difficulties in changing unhelpful behaviours (e.g. substance use disorder). MI is founded on the principles of motivational psychology, and it applies motivational strategies to elicit the patient’s intrinsic resource for change. Interventions that apply MI key concepts and principles, include Brief intervention (BI) and Motivational Enhancement Therapy (MET). MI can be delivered in a variety of settings, to different target groups, and in individual or group formats. MI is associated with significant improvements across several outcomes including reductions in substance use, symptoms of dependence, substance use related problems, as well as increases in substance use abstinence.
MI has been delivered in Scotland and across the UK.

Usability
Motivational Interviewing (MI) is a person-centred, counselling approach used to address difficulties in changing unhelpful behaviours (e.g. substance use disorder). MI is particularly focused on change, and applies collaborating conversation as a means of helping people build their motivation for change, and strengthen their commitment to change. At its core, MI applies the three key elements of collaboration, evocation of the patient’s ideas on change, and respect of patient’s autonomy, to facilitate the identification, evaluation, and resolution of ambivalence towards behavioural or attitudinal change. This is guided by a therapist who acts as a facilitator, and adopts a nonconfrontational approach to elicit the patient’s intrinsic resource for change. Hence, MI differs from other externally driven approaches. It does not apply coercive methods to impose change, but supports change in ways that are compatible with the patient’s beliefs and values.
In practice, the application of MI has four key tasks - engaging, focusing, evoking, and planning. These tasks are not linear but engaging is often a key first step in order to build engagement in preparation for conversations about change.
- MI includes basic counselling techniques that build motivation for change. It is represented by the acronym OARS that represent asking Open-ended questions, making Affirmations, using Reflections, and using Summaries.
- MI includes goal setting and a ‘change plan of action’ as a means of strengthening commitment to change. The strategies applied in this phase provide guidance to patients as they apply change talk (i.e. patient statements that express consideration of, motivation for, and commitment to change) as a path to change.
Alongside the tasks above, four principles guide the practice of MI, and should be adhered to by practitioners employing it. These are; 1) the expression of empathy by applying a non-judgemental approach to understanding the patient’s perspective; 2) supporting patient’s self-efficacy for the purpose of enhancing confidence in their capacity for change; 3) rolling with resistance in a non-judgemental manner, and applying strategies that prevent resistance from interfering with patient engagement; 4) helping patients see the discrepancies between current behaviours and future goals in order to strengthen motivation for change. MI can be delivered to children, adolescents and adults.
Fidelity
Motivational interviewing is delivered by trained practitioners with ongoing supervision. Rating scales that can be used to assess fidelity to the MI approach are outlined below and details can be found at motivationalinterviewing.org;
- Motivational Interviewing Skill Code (MISC)
- Motivational Interviewing Assessment – Supervisory Tools for Enhancing Proficiency (MIA – STEP)
- Motivation Interviewing Treatment Integrity (MITI) code
- Motivational Interviewing Target Scheme (MITS)
- Behaviour Change Counselling Index (BECCI)
Modifiable Components
MI recognises the three key components of motivation, i.e. willingness to change, the confidence to change, and readiness for change. Hence, motivational strategies applied can be tailored to suit the patient’s stage of change. MI can be delivered in a variety of settings (e.g. GP surgery, mental health settings, other health care settings), and to different target groups (e.g. probation and youth offenders, pain management, stroke recovery, and child care settings). MI has been delivered in individual and group formats (https://pubmed.ncbi.nlm.nih.gov/31821350/), and has been evaluated as a smartphone application (https://link.springer.com/article/10.1007/s41347-020-00135-w). Available evidence for MI is limited for people with substantial learning disabilities. MI can be delivered alone or integrated with CBT.
Interventions that draw on the core concepts and principles of MI include;
- Brief Interviewing (BI): This is a time-limited, structured, and goal-oriented counselling intervention to address substance use problems or other health-risk behaviours. BI can be used to prevent the development of substance use problems, protect against its progression, and help identify individuals requiring more intense intervention. BI can vary in the model used to influence change, and can adopt a range of similar yet differing techniques to achieve this. Hence, it may be entirely founded on MI core components and principles; only partly reflect MI principles and techniques; and may contain brief advice. There is also variability in BI delivery format, as it can be delivered in single or multiple sessions (e.g. one to five sessions), of varying lengths (e.g. 5-15 minutes, or 30-45 minutes), with or without written materials, or opportunities for follow-up visits. BI can include motivational interviewing, information, education and counselling on problem-solving strategies. It can commonly be delivered as an opportunistic intervention by non-specialists in primary care settings to non-treatment seeking individuals, but can also be delivered in specialist settings for substance use problems.
- Motivational Enhancement Therapy (MET): MET is a person-centred approach to therapy that is founded on the basic principles of motivational psychology. The key goal of MET is resolving or overcoming ambivalence to behaviour change. Hence, it focuses on increasing patient’s motivation to change by enhancing patient’s understanding of the problem, addressing self-defeating thoughts as it relates to the problem, and building self-confidence as it relates to the patient’s ability to change. An initial assessment is conducted prior to delivering MET for the purpose of collating information on behaviours that are associated with the problem. Following the initial assessment, MET is typically delivered over four sessions. The first two sessions focus on structured feedback (from initial assessment), future plans, and motivation for change, while the latter two sessions provide opportunities for the practitioner to reinforce progress, conduct reassessments, and provide an objective perspective on the change process. MET can be delivered as a standalone intervention or in conjunction with other psychological interventions (e.g. CBT).

Supervision Requirements
Practitioners delivering brief MI or MI skills as part of their health and social care role can be supported by coaching, reflective practice sessions and line management structures. Coaching and reflective practice sessions are provided by NES Psychology workstreams and local NHS psychology departments to support MI practice amongst health and social care professionals.
When MI is delivered as a psychological intervention (enhanced and specialist psychological practice) it is recommended that it is conducted under regular supervision with a practitioner who has expertise in a) the intervention b) the clinical area and c) has completed training in supervision of psychological therapies and interventions (Further information: https://www.nes.scot.nhs.uk/our-work/supervision-of-psychological-therapies-and-intervention/). There is additional training available on supervision of psychological interventions that specifically supports MI supervision skills.
Evidence - Rating: 5
5 - High Evidence
The intervention has demonstrated evidence of effectiveness based on at least two rigorous, external research studies with the focus population and control groups, and has demonstrated sustained effects at least one year post treatment.
Theory of Change
MI is founded on the principles of motivational psychology, and it applies motivational strategies to elicit the patient’s intrinsic resource for change. The MI approach also adopts a transtheoretical perspective, in which the individual is viewed as moving through a series of stages of change as they progress towards modifying their problem behaviour and achieving successful and sustained change.
Research Design & Number of Studies
Children and Young People - Rating: 5
Child Evidence for Substance Use
Some of the best available evidence for MI in the management of substance use disorders in adolescence come from systematic reviews with meta-analysis and Randomised Controlled Trials (RCTs).
A meta-analytic review by Calomarde-Gómez et al. (2021) evaluated the effectiveness of MI for cannabis use disorders. The meta-analysis included 16 adolescent studies that were either RCTs or open-label studies. MI was delivered in any format as there were no restrictions on mode of delivery.
A second meta-analytic review evaluated the effectiveness of brief behavioural interventions in adolescents with problematic alcohol or cannabis use (1) RCTs involving adolescents aged 12 to 20 years, meeting the criteria for at least 1 substance use disorder (SUD) or for problematic substance use (excluding tobacco) were included in the review. Interventions were designated as brief if they were delivered over 1 or 2 sessions.
The third meta-analytic study evaluated the effectiveness of brief interventions in reducing participants’ alcohol use or alcohol-related problem in adolescents (age 11-18) (2,3). It included 24 adolescent studies that were conducted in countries that included the United States. Brief Interventions in this study was defined as those delivered over five or fewer hours, over a maximum of four weeks (excluding booster sessions).
The fourth study was an RCT that evaluated the effectiveness of Brief Interventions in 315 adolescents (aged 13–18 years) who had been identified as abusing alcohol and other drugs in a school setting (in USA) (4). BI was delivered as a 2-session adolescent only intervention (BI-A) or as a 2-session adolescent and additional parent session intervention (BI-AP). Each brief intervention session was delivered individually, over 60-minutes, using a motivational interviewing (MI) style. Sessions 1 and 2 were separated by 7–10 days.
Child Outcomes
- Significant abstinence from cannabis use within 3-months (5), 6-months (4), and 12-months follow-up (6)
- Significantly reduced drug use consequences at 6-months follow-up (4)
- Significantly reduced cannabis dependence symptoms at 12-months (6)
- Significantly reduced alcohol consumption within 3- or 12-months follow-up (1); Tanner et al, 2015) and significantly reduced alcohol-related problems within 12-months follow-up (3)
Significantly reduced alcohol use days, alcohol abuse symptoms, and alcohol dependence symptoms at 6-months follow-up (4)
Adults - Rating: 5
Adult Evidence for Substance Use
Some of the best available evidence for MI in the management of substance use disorders come from systematic reviews with meta-analysis, and Randomised Controlled Trials (RCTs).
The first study was a meta-analytic review that evaluated the effectiveness of MI for cannabis use disorders (Calomarde-Gómez et al, 2021). It included 24 adult studies that were either RCTs or open-label studies. MI was delivered in any format as there were no restrictions on mode of delivery.
The second was a meta-analytic review that evaluated the effectiveness of brief interventions for non-dependent, harmful and hazardous alcohol use (7). It included 14 RCTs conducted in Low-Middle Income Countries (LMIC). Participants were aged 15– 65 years, and received single or multiple sessions (up to 6 sessions) of BI or MI, with no restrictions imposed on mode of delivery
The third was a meta-analytic study (Cochrane review) that evaluated the effectiveness of psychological interventions for cannabis use disorder in out-patient or community settings (2). The study included 23 RCTs involving 4045 adults (aged 18 years or older) who met diagnostic criteria for cannabis abuse or dependence by clinical assessment. The studies were conducted in several countries including USA, Germany, Australia, Brazil, Canada, Switzerland and Ireland. MET was delivered in different formats including as a single 60- or 120-minute MET session, two 90-minutes MET sessions, as well as 2 or 9 MET/CBT sessions.
The fourth was a meta-analytic study that evaluated the effectiveness of brief interventions in reducing participants’ alcohol use or alcohol-related problems in young adults (age 19-30) (3). It included 161 young adult studies that were conducted in countries that included the United States. BI in this study was defined as an intervention delivered over five or fewer hours, over a maximum of four weeks (excluding booster sessions).
The fifth study was a meta-analytic review of RCTs that evaluated the effectiveness of MI as a brief intervention for excessive drinking (8). Interventions in this review were delivered according to the principles and techniques of MI, and there were no restrictions on the length of delivery. The review included nine studies that compared brief MI with no treatment, and all interventions were delivered face-to-face.
The sixth study was an RCT that evaluated the effectiveness of brief alcohol intervention in 120 people attending psychiatric wards of three general hospitals in Perth, Australia (9). The participants, aged 18-64 years, were screened for excessive alcohol consumption, and were diagnosed with acute psychiatric disorders requiring short-term hospitalization. The intervention was delivered as a more intensive brief intervention in the form of an individual 45-minute motivational interview using a non-judgemental approach.
Outcomes Achieved
Compared to participants in control groups who received no treatment, minimal treatment, treatment-as-usual, or participants assigned to a waiting list, the following outcomes were observed;
Adult outcomes
- Significantly greater reduction in alcohol consumption at 3-months (8), at up to 6-months (9) and at 12-months follow-up (3)
- Significantly reduced frequency of use and quantity of use for cannabis at 3-6 months follow-up (5);(2)
- Significant abstinence from cannabis use within 3 months follow-up (5)
- Significant reduction in symptoms of dependence within 6 months follow-up (2)
- Significant reduction in cannabis-related problems at 6-months follow-up (2), and in alcohol-related problems within 12-moths follow-up (3)
- Significantly lower risk scores for hazardous and harmful drinking at 3 months assessment, not sustained at 6- or 12-months follow-up (7)
