RECRUITMENT
The strengths of this study include our relatively large sample size and racial, geographic, clinical, and gender diversity. PRIME is an innovative digital intervention targeting domains in psychotic disorders that have few alternative treatments currently available. All elements of the study were fully remote and delivered to English-speaking individuals in 8 different countries. The browser interface of cognitive training and the mobile interface of PRIME make both interventions highly scalable, although access to a laptop, a smartphone, and the internet are required. The remote nature of the interventions also created limitations in assessing the quality of engagement with TCT or CG, as we were unable to assess active and distracted engagement or random inputs (although this was likely not the case, as only 1 participant showed a cognitive training accuracy level <50%). Additional limitations arise from our sample, which was recruited on the web and consisted of highly educated participants with average baseline cognitive performance. Future studies should consider strategies to increase the recruitment of a more diverse sample.
