A grounded theory of multisystemic therapist roles in achieving positive outcomes for young people and families.

Research on the application of multisystemic therapy (MST) has focused on the experiences of caregivers, families and the young people with behavioural conduct difficulties for whom MST has been established as an effective intervention. Perspectives of MST therapists are lacking, yet hold relevance for MST model adherence and services. Using a social constructivist grounded theory approach, eight MST therapists in the United Kingdom took part in a semi‐structured interview designed to explore the requirements of the role. Data revealed four categories: two of explicit roles that included establishing rapport, engaging with families, defining the drivers to a young person's behaviour, and doing 'whatever it takes' to overcome challenges; while underpinning these were two categories of implicit roles related to coping with the organisational environment and interpersonal skill demands of the role. This study widens the understanding of both individual and organisational factors/climate and its impact on therapist performance in MST practice. Practitioner points: Supervisors need to monitor therapists' workloads, organisational climate and the emotional impact of their role, applying a greater duty of care in an ethos of doing 'whatever it takes'Maintaining engagement is a distinct and essential phase of MST. Non‐engagement can be overcome by therapists who adapt their interpersonal style to meet individual needsCollaboration with external agencies (e.g. schools) supports cross‐agency working in line with MST principles [ABSTRACT FROM AUTHOR]
