Clinical Trial Summary

This study aims to look at the effectiveness of a combination of cognitive remediation and social cognition training to improve cognition and functioning when compared to cognitive remediation alone. The target population will be those who are experiencing their first episode of psychosis.

Description:

A first episode of psychosis is defined as the first experience of positive symptoms, such as hallucinations and delusions, and the behaviour that accompanies it. This is associated with problems in many areas of cognition; the ability to acquire knowledge and understanding. These cognitive symptoms have been found to have a large impact on daily functioning (e.g. accessing education or employment and maintaining relationships) and cannot effectively be treated with medication. Cognitive remediation (CR) is a therapy that aims to improve cognition and, through generalisation of this, improve daily functioning and quality of life. Although it is an area of deficit, social cognition, the ability to perceive and understand emotional states, is often not targeted in cognitive remediation. However, interventions which have focused on providing social cognition training (SCT) alongside CR have shown large improvements in daily functioning.

This study aims to look at the effectiveness of a combination of CR and SCT to improve cognition and functioning when compared to CR alone. The target population will be those who are experiencing their first episode of psychosis. Participants will be recruited from an Early Intervention in Psychosis service which is an NHS service set up to provide rapid treatment for those experiencing psychosis.

Participants will take part in a ten week CR or CR+SCT intervention which will consist of spending 90 minutes a week in a small group setting working through a series of computer games which aim to improve cognition. Interviews and questionnaires regarding daily functioning, cognition, quality of life and symptoms will be used before and after the intervention. Participants will be asked to attend follow-up interviews 6 months after the intervention has ended to complete the measures again to see if any beneficial effects have lasted.

Behavioral:
• Cognitive remediation
CIRCuiTS is a computerised cognitive remediation program which consists of tasks to improve cognition, the use of strategy training and the teaching of generalisable community functioning skills.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Emotion Recognition Task	The emotion recognition task of the computerised Cambridge neuropsychological test automated battery (CANTAB).	10 weeks
Secondary	CANTAB schizophrenia battery	Additional computerised neuropsychological tests from the CANTAB schizophrenia battery will be used. These are the rapid visual information processing task (RVP), the spatial working memory task (SWM), the paired associates learning task (PAL), one touch stockings of Cambridge task (OTS) and the intra-extra dimensional set shift task (IED).	10 weeks and 6 month follow-up
Secondary	Specific levels of functioning scale (SLOF)	SLOF is an observer-rated set of 6 domains of functioning where ratings are made on 5-point Likert scales based on how often a particular behaviour occurs or how much help is required to perform certain tasks. The 6 domains are: physical functioning, personal care skills, interpersonal relationships, social acceptability, activities and work skills, the final four of which will be used in this study. This will be completed with the participant's primary care team and verified with the participant.	10 weeks and 6 month follow-up
Secondary	Personal and Social Performance Scale (PSP)	An additional measure of functioning, the PSP will be added on to the end of the SLOF. The PSP addresses 4 domains: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behaviours. It is scored on a 1-100 scale. This is a validated and reliable measure of functioning with high test-retest reliability. It will be completed by a member of the participant's care team.	10 weeks and 6 month follow-up
