Validating cognitive screening in young people with first-episode psychosis: The CogScreen protocol

AbstractAimCognitive impairments are a core feature of first‐episode psychosis (FEP) and one of the strongest predictors of long‐term psychosocial functioning. Cognition should be assessed and treated as part of routine clinical care for FEP. Cognitive screening offers the opportunity to rapidly identify and triage those in most need of cognitive support. However, there are currently no validated screening measures for young people with FEP. CogScreen is a hybrid effectiveness‐implementation study which aims to evaluate the classification accuracy (relative to a neuropsychological assessment as a reference standard), test–retest reliability and acceptability of two cognitive screening tools in young people with FEP.MethodsParticipants will be 350 young people (aged 12–25) attending primary and specialist FEP treatment centres in three large metropolitan cities (Adelaide, Sydney, and Melbourne) in Australia. All participants will complete a cross‐sectional assessment over two sessions including two cognitive screening tools (Screen for Cognitive Impairment in Psychiatry and Montreal Cognitive Assessment), a comprehensive neuropsychological assessment battery, psychiatric and neurodevelopmental assessments, and other supplementary clinical measures. To determine the test–retest reliability of the cognitive screening tools, a subset of 120 participants will repeat the screening measures two weeks later.ResultsThe protocol, rationale, and hypotheses for CogScreen are presented.ConclusionsCogScreen will provide empirical evidence for the validity and reliability of two cognitive screening tools when compared to a comprehensive neuropsychological assessment. The screening measures may later be incorporated into clinical practice to assist with rapid identification and treatment of cognitive deficits commonly experienced by young people with FEP.
