Does Adding Social Cognitive Remediation Therapy to Neurocognitive Remediation Therapy Improve Outcomes in Young People With a Severe Mental Illness?—The Advantage Trial

Abstract

IntroductionCognitive impairments are a common and significant issue for young people with a severe mental illness. Young people with schizophrenia, bipolar disorder and major depression all experience significant cognitive problems that impede their ability to return to work or study. These neurocognitive problems are frequently exacerbated by social cognitive deficits that interfere with their ability to integrate into the community and understand the social and emotional nuances about them. This study aimed to assess if the addition of a social cognitive remediation treatment to a neurocognitive remediation therapy improved functional outcome.MethodsFive youth mental health services were trained in both the Neuropsychological Educational Approach to Remediation (NEAR) and the Social Cognition and Interaction Training (SCIT) treatments. Participants were randomised between receiving either NEAR + SCIT or NEAR + treatment as usual (TAU) over a 20-week period, with all participants receiving the NEAR treatment first. Symptoms, neurocognition, social cognition and functioning were examined at baseline, end of treatment and at 3 months follow-up and compared between the two arms of the study. The primary outcome was function.ResultsThirty-nine participants were randomised to treatment (Schizophrenia spectrum = 28, Bipolar disorder = 7, Major Depression = 2). The trial was curtailed by Covid-related service restrictions. There was an overall significant improvement in function over time with a trend towards a greater improvement in the NEAR + SCIT arm. No changes in symptoms, neurocognitive or social cognitive measures were seen. While 74% completed treatment only 49% agreed to follow up at 3 months affecting our ability to interpret the findings. Attrition did not differ by arm.ConclusionsIn a pragmatic, service-based research project, treatment aimed at improving cognition enhanced functional outcome in young people with a range of severe mental illnesses. There was a trend towards improved function in young people who had a combined NEAR + SCIT approach.Clinical Trial RegistrationIdentifier: ACTRN12622000192785.

Cognitive remediation therapy – implementation and translation into clinical practice in rural and metropolitan New South Wales mental health services

“…Prior to 2017, provision of CRT to people living with psychosis in NSW had mostly been in the context of clinical research trials in Sydney. [16][17][18] whether the CIRCuiTS therapy program was feasible and acceptable within these contexts, which was shown to be the case.…”

Integrative Neuro-social cognitive Strategy Programme for Instilling REcovery (INSPIRE): a Community-Based Cognitive Remediation Trial-Study Procotol

“…It differs from GAF scale by focusing on social and occupational functioning independent of the overall severity of the individual's psychological symptoms. SOFAS has been used as a functional outcome measurement in cognitive remediation trials [42,43,44].…”

Efficacy of social cognition and interaction training in outpatients with schizophrenia spectrum disorders: randomized controlled trial

“…Some investigators have also reported failure to find significant group differences on any measures (26-28). While two of these trials (27,28) included active control conditions consisting of either cognitive remediation or targeted training in affect recognition, which may reasonably be thought to impact neurocognition or affect recognition narrowly, neither trial found group differences on measures of abilities uniquely targeted by SCIT. Another trial comparing SCIT to a therapeutic alliance group and treatment as usual (20) reported limited and somewhat mixed effects on measures of social cognition and social functioning and a relationship between therapeutic alliance and improvement.…”
