For app ratings, experts were selected who demonstrated knowledge and expertise in the field of software and apps for the treatment of individuals with psychotic disorders. The majority of our chosen experts had considerable experience in designing, researching, or providing these interventions to this clinical population. They were sent a comprehensive survey developed by the PsyberGuide team that asked each expert to rate a number of products on the same scales. These included the experts’ perceptions of the products’ effectiveness in a variety of domains, ease of use by their clients, etc. We then aggregated the data anonymously, deriving means on each scale for each product.
