The nuts and bolts of Cognitive Remediation: Exploring how different training components relate to cognitive and functional gains

Cognitive Remediation (CR) is an evidence based treatment targeting cognitive and functional difficulties in people with psychosis. Despite the large number of effectiveness studies, only limited evidence exists for the active ingredients of this therapy. This study begins to fill this gap by exploring the relationship between CR ingredients, including alliance with a therapist, and therapy outcomes. Method This is a secondary analysis based on data from a published randomised controlled trial comparing CR+treatment-as-usual (TAU) to TAU alone. We considered the association between CR active ingredients including errorless learning, massed practice, strategy use and therapeutic alliance on the cognitive, functioning and symptom outcomes that significantly improved following therapy. Results Forty-six of the 96 participants were randomised to CR. After therapy the CR group showed significant improvement in non-verbal memory, functioning and approaching significance, improvements in executive functions. All therapy ingredients were inter-related but strategy use alone was associated therapeutic alliance. Cognitive improvements were associated with massed practice, number of useful strategies and therapeutic alliance, but improvements in functioning were associated only with therapeutic alliance. Conclusions These findings build the evidence base for the usefulness of specific therapy components. As for other psychological therapies it appears that therapeutic alliance may be an important factor in driving change for key CR outcomes, particularly functioning, in people with psychosis.
