Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The primary goal of addressing cognitive deficits is to improve real world functioning. Cogsmart ( Cognitive Symptom Management and Rehabilitation Therapy) will be delivered once a week for 2 hours for 12 weeks. It is a manualised cognitive compensatory training program that focusses on the use of strategies to improve real world cognitive functioning ( Zaidman, Sofia Rae, "Pilot Testing CogSMART: A Novel, Compensatory Program of Cognitive Remediation for Psychosis developed by Elizabeth W. Twamley, PhD" (2016). Honors Theses). It will be delivered in 2hour weekly sessions for 12 weeks in groups of up to 8 participants with one facilitator who is trained as a cognitive remediation facilitator. The 12 modules are 1. Introduction to calendars;2. Prospective memory;3 Short term prospective memory;4. Conversational attention; 5. Task attention;6,7,8 Verbal learning and memory; 9,10,11. Cognitive flexibility and problem solving; 12 Skills integration, review and next steps. Participants have their own manual to assist with remembering sessions and homework practice.

Comparator / control treatment
Non inferiority trial comparing Cogsmart and CirCuits with primary outcome being improvement in social functioning
CIRCuiTS (Computerised Interactive Remediation of Cognition – Training for Schizophrenia). This is a modular package including tasks of a wide range of cognitive functions (particularly executive function and memory), designed to allow therapy programmes to be flexibly designed to incorporate only relevant tasks. The sessions are 1 hour twice a week for 12 weeks. Computer based program has cognitive tasks are embedded in a real world ”village” context. Abstract tasks eg decoding are combined with ecologically valid tasks eg shopping and are designed to exercise attention, memory and planning. The participants are asked to nominate strategies that they will use and after completing the tasks, rate how useful the strategies were. Sessions are delivered twice weekly for an hour and are facilitated by a mental health clinician trained as a cognitive remediation facilitator. The sessions occur in groups of up to 8 participants.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be done centrally by administrative staff who notify the program PI by email
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised once written consent has been obtained and the baseline assessments have been completed. Participants will be randomised to one of the treatment groups by a research staff not involved in therapy delivery, using blocks of 4 via a computer-generated randomization table.

Statistical methods / analysis
All analyses will be conducted in accordance with the International Conference on Harmonization E9 statistical principles, and are based on all randomised participants with at least one post-baseline observation (intention to treat population). Reporting of research findings will be done in accordance to CONSORT guidelines. The primary efficacy analysis will assess average treatment group differences for the primary outcome measure SFS, over the entire study period (baseline, endpoint, follow-up) and will use a likelihood based mixed-effects model, repeated measures approach (MMRM). The MMRM model includes the fixed, categorical effects of treatment (Cogsmart or Circuits), visit (baseline, 12 and 24 weeks), and treatment-by-visit interaction, as well as the continuous, fixed covariates of baseline score and baseline score-by-visit interaction. The MMRM includes all available data at each time point and is the preferred method of analyzing clinical trial data in psychiatry as compared to more traditional repeated measures analysis of variance (ANOVA) and analysis of covariance models (ANCOVA). Planned comparisons will be done with the MMRM models to determine between group differences in change of symptoms measures from baseline to week 12 and 24. Results from the analysis of dichotomous data will be presented as proportions, with 95% confidence interval, and Fisher’s exact p-value where appropriate. Non-parametric statistics will be used when assumptions for parametric methods are violated. Effect sizes will be calculated using Cohen’s guidelines. All tests of treatment effects will be conducted using a two-sided alpha level of 0.05 and 95% confidence intervals.
The main analyses will follow standard Intention to Treat (ITT) principals, where participants who drop out prior to the 12 week endpoint will have their Last Observation Carried Forward (LOCF). However, mindful that we expect a certain proportion of patients to drop out prior to completion (approximately 17%), we plan to undertake a Per Protocol (PP) secondary analyses. For this analyses, we will explore the impact of Cogsmart versus Cogsmart on the subset of respondents that completed at least 6 weeks of treatment.
