Harmonizing cross-cultural and transdiagnostic assessment of social cognition by expert panel consensus.

Social cognition, the perception and processing of social information, is adversely affected in multiple psychiatric, neurological, and neurodevelopmental disorders, and these impairments negatively impact quality of life for individuals across the globe. Despite the clear importance of social cognition, efforts to advance research via harmonization of data across cultures and diagnoses has been stymied by the lack of uniformly used and suitable assessments. To address this issue, the current study conducted an expert survey and consensus process to identify social cognitive assessments that are best suited for cross-cultural and transdiagnostic use among adults. A large group of experts in social cognition were surveyed to gather nominations for cross-culturally and transdiagnostically appropriate measures. These measures were then critically evaluated by a smaller group of experts using a Delphi consensus process to identify the best existing tasks for each use. Ninety-eight experts, representing 25 countries, responded to the initial survey and nominated a total of 81 tasks. Initial rounds of the Delphi process identified 50 tasks with adequate psychometric properties that were then subdivided into social cognition domains. For each domain, members ranked the five best tasks, once for cross-cultural use and once for transdiagnostic use, and rated the suitability of those tasks for the intended use. No tasks were identified as ideally suited for either use; however, within each domain, 4-5 tasks emerged as the most consistently selected, and all were ranked as having "good" or better suitability for use. While there is still a critical need for social cognitive assessments that are specifically designed for cross-cultural and transdiagnostic use, there does appear to be a handful of existing tasks that are currently available and likely informative. Caution is warranted however, as these still require comprehensive evaluation in cross-cultural and transdiagnostic studies.
