 In this article, we introduce a computational framework for evaluating psychiatric research strategies(Katahira & Yamashita, 2017). The strategies to be evaluated include a conventional diagnostic category-based approach(based on DSM or ICD)and dimensional approach that have been encouraged by the National Institute for Mental Health(NIMH), outlined as Research Domain Criteria(RDoC). The proposed framework is based on the statistical or computational modeling of the processes by which pathogenetic factors are translated to behavioral measures and how the research strategies can detect potential pathogenetic factors. The framework provides the statistical power for quantifying how efficiently relevant pathogenetic factors are detected under various conditions. We present several theoretical and numerical results highlighting the merits and demerits of the strategies. We also review a related study in which a computational approach to psychiatric nosology is proposed. We discuss how computational approaches contribute to psychiatric research.
