This study aimed to adapt and validate the Hikikomori Risk Inventory ([HRI]; Loscalzo et al., 2022) into Korean, identifying psychological risk factors related to hikikomori and providing a tool for detection and intervention. Following a translation-back translation procedure, data from 300 adults were analyzed. Factor analysis supported the original five-factor structure (agoraphobia, depressive affect, social phobia, apathy, and paranoia) though 20 of the 24 items were more suitable in the Korean context. The scale’s reliability was excellent (Cronbach’s α = .95; subfactors ≥ .82). Regarding criterion validity, risk factors correlated positively with reclusive behavior but not with adventure-seeking behavior. Mediation analysis indicated that these risk factors significantly increased the likelihood of meeting hikikomori criteria through their influence on reclusive behavior, demonstrating satisfactory criterion validity. Based on these findings, the implications of the study and recommendations for future research are discussed.
