SIFT IT: A feasibility and preliminary efficacy randomized controlled trial of a social cognition group treatment programme for people with acquired brain injury.

Making sense of social situations requires social cognitive skills, which can be impaired after acquired brain injury (ABI), yet few evidence-based treatment options are available. This study aimed to evaluate the feasibility of a multi-faceted social cognition group treatment programme, SIFT IT, for people after ABI using an RCT design. Twenty-eight participants were recruited, and 23 were randomized into either Treatment or Waitlist. SIFT IT consisted of 14 weekly 90-minute small group sessions facilitated by a Clinical Psychologist. Topics included: emotion self-awareness, emotion perception, perspective taking, and choosing adaptive social responses. Preliminary efficacy outcomes were assessed at baseline, post-treatment, and three-month follow-up. Demand for treatment was evident with 61% recruitment and 91% post-treatment retention rates, with 63% attending at least 13/14 sessions. Large between-group treatment effects (with non-zero 95% confidence intervals) were observed for emotion perception, detecting hints, and informant ratings of social cognitive deficits. Implementation challenges recruiting to groups and maintaining group allocation fidelity, with a small sample size does, however, raise questions about the appropriateness of an RCT design in a future efficacy trial. Overall, this study showed there is demand for social cognitive interventions after ABI and the SIFT IT programme was practicable and acceptable to participants.Trial registration: Australian New Zealand Clinical Trials Registry identifier: ACTRN12617000405314.
