The purpose of this study was to conduct evidence based research for reason of Prolonged Social Withdrawal (Hikikomori). In this study, two hundreds forty eight parents who had individuals in the state of “Hikikomori” were asked to complete a questionnaire on the Reason of “Hikikomori” checklist (RHCL). Results of the factor analysis revealed that RHCL includes 16 items which consist of four factors including “Attention getting”, “Avoidance of social interaction”, “Avoidance of outing”, and “In-home reinforcement”. Furthermore, it was suggested that RHCL had sufficient internal consistency, criterion-related validity, content validity and construct validity. As a result of cluster analysis, “Avoidance of social interaction group”, “General avoidance group”, “General avoidance/ reinforced group”, and “Non-avoidance/non-reinforced group” were revealed. Finally, the utility of RHCL and the future study on intervention for individuals in the state of “Hikikomori” were also discussed.
