Therapist and supervisor experiences of the application of standard Multisystemic therapy to young people with suspected or diagnosed level 1 autistic Spectrum disorder

Abstract

Multisystemic Therapy (MST) is an intervention offered to young people presenting with antisocial and aggressive behaviour and is currently being adapted for use with the autism spectrum disorder (ASD) population. This qualitative study aimed to provide the first consideration of the experiences of MST therapists and supervisors of delivering standard MST to young people with suspected or diagnosed Level 1 ASD. Semi-structured interviews were carried out with 11 MST therapists and supervisors with experience of working with the client group. Thematic analysis identified three major themes: (1) nuanced delivery of MST for Level 1 ASD, (2) need for knowledge and resources, and (3) positive experiences with delivering the intervention. Findings suggested the need for an increased focus on understanding the individual needs of a young person in assessment and intervention, the increased importance of structure and consistency, and psychoeducation for all systems around the young person in order to meet the developmental needs of young people with Level 1 ASD.
