Brief & Practical

Motivational Interviewing as an Integration within the ShiftGrit Core Method™

Overview

Motivational interviewing (MI) is a collaborative, client-centred counselling style for strengthening a person's own motivation and commitment to change. It is a directive yet non-confrontational method that helps clients explore and resolve ambivalence about a behaviour rather than having change imposed on them.

How it works

The clinician works in partnership with the client, using open-ended questions, reflective listening, affirmations, and summarizing to evoke the client's own reasons for change. The approach deliberately elicits and reinforces "change talk" while reducing resistance, honouring client autonomy and avoiding argumentation or persuasion. Change is understood to follow when the person voices and resolves their own ambivalence, rather than from external direction.

What it is used for

MI was first applied to alcohol and other substance use disorders and remains widely used for addictive behaviours, smoking cessation, and reducing risky drinking. It has since been extended to a broad range of health-behaviour and clinical contexts, including medication and treatment adherence, diet, physical activity, weight management, chronic-disease self-management (such as diabetes), and as an adjunct for anxiety, depression, and other mental-health presentations involving ambivalence about change.

Origins and evidence base

MI was developed by clinical psychologist William R. Miller, who first described it in a 1983 article in Behavioural Psychotherapy, and was elaborated with Stephen Rollnick in their 1991 book Motivational Interviewing: Preparing People to Change Addictive Behavior (now in its fourth edition, Helping People Change and Grow, 2023). It has a substantial empirical base, with numerous randomized controlled trials and multiple meta-analyses supporting its efficacy across substance use and other health behaviours, though effect sizes vary by population, target behaviour, and implementation fidelity.

Within the ShiftGrit Core Method™

People sometimes picture motivational interviewing as the thing that does the changing, a way of being talked or coached into a different life. We use it for something narrower and earlier than that. When part of a person wants something different and another part holds back, our clinicians use it as a gentle, collaborative conversation designed to help clients voice their own reasons for change, in their own words, without anyone pushing or arguing against them. Across every client, the heart of how we work is the ShiftGrit Core Method™, which draws together Pattern Theory™, work on the limiting belief beneath a pattern, and the way our clinicians deliver that work session to session. Motivational interviewing is an evidence-based approach a clinician may draw on alongside that work, not in competition with it. Where ambivalence is loud and a person feels split, it can help settle that internal tug-of-war so someone is ready to engage the Core Method™ wholeheartedly. As that readiness grows, motivational interviewing can ease off, and the Core Method™ carries on as the steady work it has been all along.

Illustrative example

Imagine someone whose pattern is to over-control and overwork, tied to the belief "I am not in control." They say they want to ease their grip, then find themselves tightening it again, because letting go feels unsafe. Early on, our clinician might use a motivational interviewing conversation to help them put into their own words what the over-control is costing them and why they want something different, so the part of them invested in control feels heard rather than overridden. With that ambivalence eased, the Core Method™ work on the belief at the root can carry on, and the over-control can begin to settle.
