Observational StudyOutcomes From Remediation and Behavioural Intervention Techniques

Individual formulation-based CBT will be delivered for one hour per week using a manual that has been validated in over 1000 individuals with schizophrenia-spectrum disorders across all stages of illness.

Sham CR was developed by Dr. Best and Dr. Bowie (CI) to control for the non-specific effects of CR such as computer practice and group discussion.

Action-based cognitive remediation (ABCR) will be delivered in group sessions one hour per week. ABCR was developed by Dr. Bowie (CI) and Dr. Best (PI) and has been found efficacious for schizophrenia-spectrum disorders in three clinical trials.

Befriending will be delivered according to a manual validated to control for the non-specific effects of CBT, such as duration of therapeutic contact, client expectancy effects, therapeutic alliance, and therapist warmth.

Individual formulation-based CBT will be delivered for one hour per week using a manual that has been validated in over 1000 individuals with schizophrenia-spectrum disorders across all stages of illness. This approach has demonstrated moderate to large improvements on symptoms and small to moderate effects on functioning. The first four sessions are devoted to building therapeutic rapport and developing collaborative treatment goals. The following phase focuses on developing formulations of why difficulties persist and using cognitive and behavioural change strategies. A longitudinal formulation is then offered to better understand how their difficulties developed. The final 2-4 sessions focus on consolidating the learning that occurred during treatment so that participants can maintain their improvement. Therapy homework is collaboratively assigned at the end of sessions to promote new learning in between sessions.

Action-based cognitive remediation (ABCR) will be delivered in group sessions one hour per week. ABCR was developed by Dr. Bowie (CI) and Dr. Best (PI) and has been found efficacious for schizophrenia-spectrum disorders in three clinical trials. ABCR involves practicing computerized training exercises with difficulty level dynamically titrated to improve neurocognitive abilities. Then participants engage in strategy discussions with other group members to develop new cognitive strategies. Finally, participants complete role-play simulations of real-world activities to practice their cognitive strategies in simulations of everyday life. ABCR is more effective for improving functioning than traditional approaches to CR. Homework consists of additional cognitive training and practicing cognitive strategies in everyday life.

Befriending will be delivered according to a manual validated to control for the non-specific effects of CBT, such as duration of therapeutic contact, client expectancy effects, therapeutic alliance, and therapist warmth. Befriending consists of 1-hour individual sessions once per week and involves a series of conversations similar to those one might have with a social acquaintance. These conversations involve discussion of neutral topics without problem-solving, coping strategies, or exploration of emotion. If emotional or mental health-related topics are brought up therapists redirect back to a neutral topic.

Sham CR was developed by Dr. Best and Dr. Bowie (CI) to control for the non-specific effects of CR such as computer practice and group discussion. Participants practice similar computerized exercises to ABCR, however, the exercises do not increase in difficulty. Participants then discuss enjoyment of the exercises but any discussion of cognitive strategies is redirected back to a neutral topic. We have previously found this condition to be an effective control for CR, with similar engagement to the active training group.
