Adapting CBT for social anxiety in autism: the feasibility and acceptability of a modified group intervention based on the cognitive model of Clark and Wells (1995)

Abstract Social anxiety disorder (SAD) is one of the most prevalent co-occurring conditions amongst cognitively unimpaired autistic people. The evidence-based treatment for social anxiety known as cognitive therapy for SAD (CT-SAD) may to an extent be beneficial to autistic people, but adaptations for autistic people are recommended to increase its effectiveness. The present study aimed to co-produce and pilot an adapted SAD treatment protocol for autistic people based on the Clark and Wells (1995) model, including assessing its feasibility and acceptability. A bespoke 12-week CBT online group intervention was created to meet the needs of autistic people with a diagnosis of SAD. The treatment protocol was created collaboratively with autistic people. It was piloted with seven adult participants (three males, four females) with autism or self-identified autism who completed the group intervention targeting SAD symptoms. With regard to feasibility, we met our initial aims of recruiting our intended sample size of a minimum of six participants for the intervention with an attendance rate of at least 80% of sessions. The excellent completion and attendance rates, respectively 100% and 95%, indicate that the intervention was acceptable to our participants. These findings extend previous research and support the continued adaptation of CBT interventions for autistic people. Furthermore, the evidence of feasibility indicates that further study to evaluate the efficacy of this group intervention is warranted. Key learning aims (1) To reflect on social anxiety, autism and identify ways to improve the delivery of cognitive therapy for autistic people. (2) To identify useful adaptations to cognitive therapy for autistic people. (3) To learn how to deliver group cognitive therapy remotely for autistic people who present with social anxiety.
