Background: Overall results from Cognitive Remediation (CR) indicate robust and long-lasting effects with medium effect size on global cognition and functioning, and a small ES on symptoms present at post-treatment but not at follow-up. However, results are not the same in all CR therapies and in some cases no efficacy results are achieved.
Aims: To develop an integrative intervention taking into account previous efficacious therapies. To evaluate the efficacy of our cognitive remediation group training: Problem Solving and Cognitive Flexibility training (REPYFLEC), with the aim of improving cognition and functioning in schizophrenia patients.
Method: Participants with a diagnosis of schizophrenia or schizoaffective disorder (n=62) were randomized to 32 group sessions of REPYFLEC CR, or to 32 group sessions of activities without specific objectives and focused on leisure. In both groups the sessions were conducted twice a week. Functioning and psychiatric symptoms were measured at baseline (week 0) and thereafter at 8, 16 and 40 weeks. Cognition was measured at weeks 0, 16 and 40. Mixed Models were used to estimate statistical differences.
Results: Patients in the cognitive remediation group demonstrated significant improvements in executive function, negative symptoms and functioning at post-treatment compared with patients in the control group. At 6-month follow-up, significant improvements in executive function and functioning remained.
Conclusion: These results apparently show that REPYFLEC works as cognitive remediation training, improving executive thinking and functioning outcomes compared with a control group.

Background And Aims: For young children with intractable epilepsy caused by congenital abnormalities or acquired cortical lesions, pediatric hemispherectomy surgery (pHS) may offer the only path to seizure remediation. Although some sensory and motor outcomes of pHS are highly predictable, the long-term cognitive and functional sequelae of pHS are far more variable. With the aim of identifying potential post-pHS intervention targets, the current study examined daily executive functioning and self-awareness in adults with pHS and broadly intact cognitive outcomes (indicated by average or above performance on intelligence tests).

This study examined the feasibility and initial effectiveness of integrating a new cognitive remediation program, Thinking Skills for Life (TSL), into independent living skills training programs in four secure residential treatment facilities (SRTFs) to facilitate discharge to more independent living situations. Participants were 30 individuals in the SRTF, of whom 11 were forensically committed to the SRTF.

In the last decades, research from cognitive science, clinical psychology, psychiatry, and social neuroscience has provided mounting evidence that several social cognitive abilities are impaired in people with schizophrenia and contribute to functional difficulties and poor clinical outcomes. Social dysfunction is a hallmark of the illness, and yet, social cognition is seldom assessed in clinical practice or targeted for treatment. In this article, 17 international experts, from three different continents and six countries with expertise in social cognition and social neuroscience in schizophrenia, convened several meetings to provide clinicians with a summary of the most recent international research on social cognition evaluation and treatment in schizophrenia, and to lay out primary recommendations and procedures that can be integrated into their practice.

Research has shown that heightened emotionality often precedes psychotic experiences. Understanding how individuals cope with these emotions is crucial for psychosis. While prior studies on emotion regulation (ER) and psychosis have mainly relied on self-report questionnaires, recent research has increasingly utilised daily life methods.

Background: Clinical reasoning is a professional capability required for clinical practice. In preclinical training, clinical reasoning is often taught implicitly, and feedback is focused on discrete outcomes of decision-making. This makes it challenging to provide meaningful feedback on the often-hidden metacognitive process of reasoning to address specific clinical reasoning difficulties.
