Previous case-study research has explored the efficacy of motivational interviewing (MI) as a therapeutic approach for supporting young people in schools. This article considers how MI may additionally be used as an assessment and consultation tool for ascertaining the needs of disaffected young people and identifying appropriate support strategies. Here, the approach is used with three pupils aged 13-15 years, using visual stimuli to involve them explicitly in the process of MI. Findings indicate that in general MI was felt by the young people to be helpful in allowing them to think about issues relating to their behaviour. The article also indicates that MI may be useful both as an initial assessment tool and in providing supporting adults with practical ideas for assisting disaffected young people in making positive changes to their behaviour. The authors acknowledge limitations in terms of the usefulness of this approach for pupils who may be less ready for change, have difficulty in identifying aspirational goals or have language and communication difficulties. Further larger scale research is recommended, including other vulnerable groups, such as excluded pupils or school refusers. (Contains 1 figure and 3 notes.)
