Socratic guided feedback therapy after acquired brain injury: A multicenter randomized controlled trial to evaluate effects on self-awareness.

ABSTRACT

Impaired self-awareness after acquired brain injury (ABI) challenges neuropsychological rehabilitation. The current study aimed to compare the effects of Socratic Guided Feedback therapy to usual care in a multicenter randomized controlled trial with 64 participants with reduced self-awareness after ABI. The objectives were to study the effects on (1) self-awareness and (2) motivation for and participation in therapy, mood, quality of life, and social participation. Patients were recruited from rehabilitation centres in The Netherlands and Belgium. They were 50.8 (±16) years old and 2.7 months (±1.8) post-injury at baseline. Session duration ranged from 20-60 minutes and the number of sessions ranged from 1 to 162 sessions. Self-awareness increased over time in both groups. Between 9 and 12 months after baseline measurement, self-awareness (Patient Competency Rating Scale discrepancy score between patient and significant other) improved in the experimental group and deteriorated in care as usual. No significant differences were found on secondary outcome measures. In conclusion, Socratic Guided Feedback therapy is as effective as care as usual but provides a structure for therapists. We recommend further investigation of the added value of Socratic Guided Feedback therapy in later follow-up measurements, group therapy settings, and on other outcome domains such as caregiver burden.
