Motivational Interviewing

What is Motivational Interviewing (MI)?

Motivational Interviewing is a collaborative, person-centered approach for strengthening motivation and commitment to change. As defined in the 2023 fourth edition, MI is "a particular way of talking with people about change and growth to strengthen their own motivation and commitment."

Originally developed to support individuals with addiction, MI has evolved into a widely used method across healthcare, education, coaching, and human services. It's built on the understanding that ambivalence about change is normal — and that lasting transformation begins with the individual's own reasons for change.

Core Goals of MI

MI isn't about persuading or directing — it's about guiding. Practitioners help individuals:

• Explore personal values and goals
• Resolve ambivalence about change
• Strengthen intrinsic motivation
• Develop actionable plans for change

What is "Change Talk"?

Change talk refers to any statement that reflects desire, ability, reason, or need for change. It's a central indicator of progress in MI. Practitioners listen for and reinforce change talk to help individuals build momentum and confidence toward action.

Is MI an Intervention?

Yes — and more. MI functions both as a standalone intervention and as a complement to other modalities. Its effectiveness lies in its adaptability and emphasis on empathy, autonomy, and strategic guidance. Key principles include:

• Expressing empathy
• Developing discrepancy between current behaviour and stated values
• Rolling with resistance rather than confronting it
• Supporting self-efficacy and belief in the ability to change

Is MI Evidence-Based?

Absolutely. MI is one of the most rigorously studied communication methods in the world.

Supported by over 2,000 clinical trials and decades of research across diverse populations and settings, MI is recognised as an evidence-based practice for substance use treatment, chronic disease management, mental health support, and behaviour change in youth and adults.

The OARS Framework

MI practitioners use four foundational communication skills — collectively known as OARS — to build rapport, elicit change talk, and guide conversations:

How MI Works in Practice: The Four Core Processes

Unlike directive or advice-driven counselling, MI is a guiding style that invites individuals to reflect on their values, goals, and readiness for change. The process is structured around four interconnected tasks:

MI Techniques That Drive Change

Motivational Interviewing is more than a set of tools — it's a mindset. That said, key techniques include:

How Effective Is MI?

MI has demonstrated strong outcomes in:

• Reducing substance use and supporting long-term recovery
• Improving treatment retention and programme completion
• Enhancing mental health outcomes across diverse populations
• Supporting lifestyle changes (diet, exercise, smoking cessation, medication adherence)

Its strength lies in helping people move from uncertainty to action — on their own terms.

Examples of MI Questions

Effective MI questions invite exploration and self-discovery. Here are key questions that spark meaningful dialogue:

• "What would you like to see different about your current situation?"
• "How confident are you in your ability to make this change?"
• "What worries you most about making this change?"
• "What support do you need to succeed?"
• "What are the benefits of changing — and the costs of staying the same?"

These questions help individuals articulate their own reasons for change, which is the heart of MI.

MI Training & Certification

While no formal licence is required to practice MI, structured training and feedback are essential for proficiency. Training options include:

• Online On-Demand: Self-paced masterclasses from EBP Society and EBP Hub
• Live EB Pathways Conferences: Interactive, instructor-led MI sessions (Steps 1, 2 & 3)
• Private Programmes: Customised delivery for your team, virtually or on-site
• MINT: The Motivational Interviewing Network of Trainers — a global community of certified MI trainers

Building MI Capacity In-House

Agencies can benefit significantly from developing internal MI expertise. Advantages include:

• Cost savings over time vs. repeated external training
• Consistent client experience and service delivery standards
• Tailored training for specific populations and contexts
• Sustainable onboarding and ongoing skill refreshers
• Empowered staff and improved retention

1. Train frontline staff in MI fundamentals — the OARS skills and core principles
2. Equip supervisors to coach and reinforce MI skills in day-to-day practice
3. Develop internal trainers to sustain long-term capacity independent of external providers

The EBP Society MI Skills Pathway (Steps 1, 2 & 3) is designed precisely around this three-tier model.

MI Across Industries

Originally developed for substance use disorders, MI has evolved into a versatile communication method used across a wide range of sectors. Its core principles — collaboration, empathy, and autonomy — make it a powerful tool in both clinical and non-clinical environments.

The History of MI

Motivational Interviewing emerged in the early 1980s through the work of clinical psychologists William R. Miller and Stephen Rollnick. Initially developed to support individuals with alcohol use disorders, MI has since evolved into a widely adopted approach across healthcare, education, criminal justice, and organisational development.

The method grew from a convergence of behavioural science and client-centered therapy, emphasizing empathy, autonomy, and collaboration. Today, MI is recognised as a dynamic, evidence-based style of communication that helps people explore and resolve ambivalence about change.
