Description of intervention(s) / exposure
The primary aim of this study is to validate a cognitive screening tool for young people with first-episode psychosis (FEP). We aim to evaluate the classification accuracy (relative to a neuropsychological assessment reference standard) and test-retest reliability of two cognitive screening tools in young people with FEP: the Screen for Cognitive Impairment in Psychiatry (SCIP) and Montreal Cognitive Assessment (MoCA).
All participants (N=350) will complete both cognitive screening measures (MoCA and SCIP), neurodevelopment assessment, psychiatric assessment, and other supplementary measures (e.g., other clinical measures and acceptability questionnaires). The assessments will be separated into two days: day 1) cognitive screening tests and psychiatric and developmental assessment, and day 2) full neuropsychological assessment. Day 1 is estimated to take 3 hours. The self-report measures will be split across both days to reduce participant burden, and will either be completed in person or the participant may choose to complete these measures at home.
The assessments on each day will be completed by separate members of the research team, ideally conducted within seven days of each other. The assessment will be completed by a trained research assistant and will be administered under the remote supervision of a clinical neuropsychologist. The cognitive screening measures, neurodevelopmental and psychiatric assessments, and full neuropsychological assessment will likely occur at each of the participating sites (e.g., Orygen Specialist Program, Headspace) or at a location in the community (e.g., local library). The self-report supplementary measures will be completed in person or the participant may choose to receive a link to complete these measures at home.

Test-retest assessment time-point (N=120)
The SCIP and MoCA will be re-administrated to a sample of 120 people who completed the classification accuracy component of the study after two weeks (T2). Version 1 of the MoCA and SCIP will be administered to 60 consecutive participants and Version 2 to 60 consecutive participants for the retest reliability part of this study to determine the role of practice effects in the test-retest analysis. Both Version 1 and Version 2 of the MoCA and SCIP are validated measures and follow the same structure and scoring (changes to the item content only).

A secondary aim of this study is to conduct a comprehensive implementation evaluation with key stakeholders during the recruitment period for the classification accuracy study using mixed methods. Following the administration of the MoCA and SCIP, all participants (N=350) will complete a brief self-report survey (i.e., two surveys per participant) which will collect data regarding the initial acceptability of the MoCA and SCIP (e.g., “Did you like/dislike the MoCA?”, “How much effort did it take to do the SCIP?”). To further explore the key perspectives about the acceptability, feasibility, and appropriateness of cognitive screening and identify the facilitators and barriers to implementation in FEP settings, a subset of young people with FEP (n=10-30) will be invited to participate in an interview or focus group to share their experiences of cognitive screening. This interview/focus group is likely to occur a within 3 months after completing the MoCA and SCIP. We will also invite other stakeholders in FEP treatment settings (i.e., clinicians, caregivers, service leaders) to participate in separate interview or focus groups as part of a comprehensive implementation evaluation.

Diagnosis / Prognosis
Comparator / control treatment
No control group will be used. Screening tests (index tests) for each participant will be compared to gold-standard neuropsychological tests (reference tests) for each participant to determine the accuracy of index tests in identifying cognitive difficulties in young people experiencing first episode psychosis. These gold-standard neuropsychological tests are a collection of computerised tests used to measure thinking and memory skills on iPads. These tests will take place on day two (a week after participants complete the screening tests) and is estimated to take approximately 2-3 hours, including breaks.

Reference standard neuropsychological tests include:
1. Core subtests of the Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V, for those aged 12-15) or Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV, for those aged 16-25). This is to obtain IQ and cognitive factor scores.
2. California Verbal Learning Test, Children’s Version (CVLT-C, for those aged 12-15) or California Verbal Learning Test, 3rd Edition (CVLT3 for those aged 16-25). This to measure verbal learning and memory for lists of information.
3. Logical Memory from the Wechsler Memory Scale-Fourth Edition (for those aged 16-25 only). This is to measure verbal learning and memory for stories. There is no equivalent measure for young people under 16 on Q-Interactive.
4. Verbal Fluency subtest from the Delis-Kaplan Executive Function System (D-KEFS). This is to measure verbal fluency.
5. Word Reading and Sentence Comprehension subtests from the Wide Range Achievement Test-Fifth Edition (WRAT5). This is to measure Reading Achievement Composite.

Implementation evaluation for young people with FEP – The aim is to explore the acceptability of the cognitive screening tools (i.e., MoCA and SCIP) for young people with FEP. All young people with FEP who complete the diagnostic accuracy component of the study (n= 350) will complete a brief self-report survey (Acceptability Questionnaire) which will collect data regarding the initial acceptability of the MoCA and SCIP. This questionnaire has been developed specifically for this study and contains several closed- and open-ended questions that aimed to explore a young person’s perspectives of completing cognitive screening. The items have been adapted from a published measure based on the Theoretical Framework of Acceptability (TFA) model and include likert-scales, multiple choice, and open text answer options. This measure will be administered immediately after cognitive screening has been completed with the young person.
Timepoint [2] 418275 0
The self-report measure occurs immediately following completion of the MoCA/SCIP on day 1 of the assessment.
Secondary outcome [3] 418276 0
To further explore the key perspectives about the acceptability, feasibility, and appropriateness of cognitive screening and identify the facilitators and barriers to implementation in FEP settings, key stakeholders in FEP treatment settings (i.e., clinicians, caregivers, service leaders) will be invited to participate in a separate interview or focus groups as part of a comprehensive implementation evaluation. Interviews will be semi-structured, facilitated by one member of the research team, and may occur face-to-face or online. Focus groups will be semi-structed, facilitated by two members of the research team, and may occur face-to-face or online.
Timepoint [3] 418276 0
These interviews or focus groups will occur throughout the duration of the study. Based on established recommendations for reaching data saturation in theory-based studies, interviews will be conducted with a minimum n=10 and stopped after three consecutive interviews where no new findings emerge (Francis et al., 2010). Alternatively, will conduct 3 – 6 focus groups, which has been shown to identify 90% of all themes (Guest et al., 2017; Hennink et al., 2019).

Statistical methods / analysis
Sample size:
The sample size needed for the diagnostic accuracy study has been calculated based on considerations for the expected rate of clinically significant cognitive impairment (i.e., approximately 70-75%), sensitivity and specificity of greater than or equal to 80%, and 95% confidence intervals (+/- 5%). A sample of 350 is needed to achieve these parameters (Malhotra & Indrayan, 2010).

Clinical cognitive impairment will be defined as either: (1) greater than or equal to 2 cognitive domain scores 1.5 SD below population mean on the reference test normative data, or (2) Full-Scale IQ <80 on the WISC/WAIS. This will be based on data collected from the standardised neuropsychological battery (i.e., STARD Reference Standard). The study will first examine the performance of the typical cut-off scores of the SCIP (<70) and MoCA (<26) (STARD Index measures) followed by exploration of the performance of other cut-scores using logistic regression analyses. Several indicators of classification accuracy will be calculated using logistic regression analysis (e.g., sensitivity and specificity, and LR+/-). LRs will be used to assist estimation of post-test probability across a relevant range of prevalence. Intra-class correlation coefficients for absolute agreement will used for the retest reliability analysis.

To test the hypotheses that both cognitive screeners will show accurate classification accuracy and retest reliability, a sensitivity and specificity of 80%, LR+ of greater than or equal to 5, LR- of <.1, and an intra-class correlation coefficient of 0.80 will be considered acceptable (Bowden et al., 2017).

To test the hypothesis that the classification accuracy of the SCIP will be superior to the MoCA, their relative positive and negative LRs will be compared using the formula in Hayen et al. (2010). If one of the screeners is not superior on both LR+/-, we will use the formula in Biggerstaff et al. (2000) to determine superiority.
