Motivational Interviewing (MI)
The strongest motivation is not imposed from outside: it is evoked when people hear and take ownership of their reasons for change.
Motivational Interviewing (MI) is a collaborative, person-centred clinical method of conversation deliberately oriented towards a direction of change, whose purpose is to strengthen the client's own motivation and commitment. It emerged in 1983 in the treatment of alcohol problems as an alternative to explanations that attributed lack of change to stable traits of denial, resistance or weak will. It regards motivation as a dynamic, interpersonal process: how one listens, asks, reflects, informs and responds can increase exploration, agency and change talk, or provoke sustain talk, reactance and discord. Its practice combines a relational component—partnership, acceptance, compassion and empowerment—with a technical component that recognises, invites and strengthens language in favour of change while responding without confrontation to language favouring maintenance of the status quo. It is organised recursively into four tasks—engaging, focusing, evoking and planning—and uses skills such as open questions, affirmations, reflective listening and summaries, along with procedures to clarify values, develop discrepancy, explore importance and confidence, provide information with permission, consolidate commitment and build feasible plans. MI can be used as a stand-alone brief intervention, as a style for providing feedback or as a way of integrating other treatments, but it does not replace the specific skills, resources or interventions a person may need once they have decided to change.
Theory of change
People change when a collaborative, non-coercive relationship allows them to explore ambivalence, hear their own reasons and abilities, strengthen commitment and turn it into feasible decisions and steps.
Core ideas
-
Motivation is not a fixed client trait
MI replaced explanations of unwillingness, denial or resistance as internal defects with a dynamic, interpersonal conception. Readiness can increase or decrease according to context, practitioner style, degree of choice and the way change is discussed. (Miller, 1983; Rollnick & Miller, 1995).
-
Ambivalence is a normal condition of change
Wanting and fearing change at the same time is not irrational: each option contains gains and losses. The clinical task is to allow both poles to be expressed and organised until the person can choose, not to win an argument against the side that wants to preserve the status quo. (Rollnick & Miller, 1995; Miller & Rollnick, 2023).
-
Spirit precedes and regulates techniques
Questions, reflections and scales do not constitute MI if they are used to manipulate or lead to a predetermined conclusion. Partnership, acceptance, compassion and empowerment determine when, how and why each procedure is used. (Miller, 2023; Miller & Rollnick, 2023).
-
MI guides without appropriating the decision
The practitioner does not remain neutral when there is a shared goal: they strategically guide the conversation towards it. At the same time, the person retains freedom of choice and responsibility, so directionality must be distinguished from pressure, persuasion and coercion. (Rollnick & Miller, 1995; Miller & Rollnick, 2023).
-
Empathy is an active component
The origins of MI are linked to unexpected findings about the association between practitioner empathy and outcomes. Accurate listening changes the interpersonal climate, reduces defensiveness and enables a more complex exploration of change; it is not merely a non-specific condition of kindness. (Miller & Rose, 2009; Miller, 2023).
-
The corrective reflex can have the opposite effect
When the practitioner presents the arguments for change, the client may take the complementary role of defending maintenance. The interaction reinforces sustain talk, reactance and discord despite the benevolent intention to help. (Miller, Benefield, & Tonigan, 1993; Miller & Rollnick, 2023).
-
Resistance provides information about the interaction
MI does not deny the existence of personal barriers, but understands many oppositional responses as feedback about pressure, a mismatch in focus or premature progress. The appropriate intervention is to change one's own behaviour, restore autonomy and repair collaboration. (Miller, 1983; Rollnick & Miller, 1995).
-
Change talk and sustain talk are sides of motivational conflict
Both types of language may increase when exploring ambivalence and should not be interpreted morally. What is clinically relevant includes their strength, proportion, sequence, context and transformation into commitment, not merely the absolute frequency of utterances. (Amrhein et al., 2003; Magill et al., 2014).
-
Discord is not sustain talk
Sustain talk concerns the goal and may occur within an excellent alliance; discord concerns the relationship and how the conversation is unfolding. Confusing them leads to treating a relational rupture as though it were a lack of motivation. (Miller & Rollnick, 2023).
-
Commitment is more than expressing reasons
Desire, ability, reasons and need prepare for change, but moving to action requires mobilising language. The strength of commitment when considering a plan showed predictive capacity and deserves to be heard without eliciting forced promises. (Amrhein et al., 2003).
