RESUMEN
Working memory-based cognitive remediation therapy (CT) for psychosis has recently been associated with broad improvements in performance on untrained tasks measuring working memory, episodic memory and IQ, and changes in associated brain regions. However, it is unclear whether these improvements transfer to the domain of social cognition and neural activity related to performance on social cognitive tasks. We examined performance on the Reading the Mind in the Eyes test (Eyes test) in a large sample of participants with psychosis who underwent working memory-based CT (N = 43) compared to a control group of participants with psychosis (N = 35). In a subset of this sample, we used functional magnetic resonance imaging (fMRI) to examine changes in neural activity during a facial emotion recognition task in participants who underwent CT (N = 15) compared to a control group (N = 15). No significant effects of CT were observed on Eyes test performance or on neural activity during facial emotion recognition, either at p < 0.05 family-wise error or at a p < 0.001 uncorrected threshold, within a priori social cognitive regions of interest. This study suggests that working memory-based CT does not significantly impact an aspect of social cognition which was measured behaviourally and neurally. It provides further evidence that deficits in the ability to decode mental state from facial expressions are dissociable from working memory deficits, and suggests that future CT programmes should target social cognition in addition to working memory for the purposes of further enhancing social function.
RESUMEN
Cognitive remediation (CR) training improves cognition and functioning in patients with psychosis. To date, however, few studies have investigated CR from a subjective patient perspective. We recently conducted a randomized control trial demonstrating the effectiveness of a new, low therapist support, computer-based training program. This study aims to assess the service user experience of this program. Twenty CR completers with psychosis were interviewed using both rated and open-ended questions. Thematic analysis identified three broad themes: a) benefits of doing CR, b) costs of doing CR, and c) experience of doing CR. Positive experiences of therapy participation included improved cognition, improved positive self-regard, a development of life skills, and a transfer of benefits to everyday life. Negative experiences included therapy being difficult and tiring, leading to frustration and anxiety. These findings demonstrate the feasibility of low therapist support CR and point to variables that might impact therapy adherence.

Cognitive remediation (CR) has emerged as the treatment of choice for impaired cognition in psychosis. However, little is known about adherence rates and factors predicting adherence to CR, particularly in clinical settings where high-level therapist support is unavailable. This study aimed to establish adherence rates and examine variables predicting adherence to a computerized CR program for psychosis (with minimal support). Patients with psychosis (n = 61) participated in an 8-week CR program. Results showed 46% completed a meaningful amount of CR training. The fully adherent (>80% of the prescribed amount) and nonadherent groups differed where adherent participants had poorer working-memory and higher negative symptom scores. These findings suggest that approximately half of the sample were adherent to treatment despite minimal therapist support. Furthermore, higher cognitive deficits and negative symptoms did not impede adherence, and may have contributed to patients' motivation to complete the program.
