Psychological Factors Associated with Social Withdrawal (Hikikomori)

Objective Cases of prolonged social withdrawal (hikikomori) have recently been reported in several countries. This study examined the impact of cognitive-behavioral and emotional factors on hikikomori behavior to identify intervention targets. Identifying such targets could facilitate the development of techniques to address hikikomori characteristics. Methods Two hundred Japanese individuals (mean age=38.73, SD=6.85) completed the Adaptive Behaviors Scale for Hikikomori and Stress Response Scale-18, along with the Japanese versions of the Self-Compassion Scale (Short Form), Acceptance and Action Questionnaire- II, and Brief Coping Orientation to Problems Experienced Inventory. Participants were divided into two groups: individuals with no experience of social withdrawal, and those with experience of social withdrawal. Results Hierarchical multiple regression analysis showed that the use of instrumental support, behavioral disengagement stress coping skills, self-compassion, and psychological stress were associated with hikikomori behaviors. Furthermore, higher instrumental support levels, associated with a decrease in hikikomori behaviors, were found in the hikikomori group. Conclusion The use of instrumental support, behavioral disengagement stress coping skills, self-compassion, and psychological stress should be targeted in hikikomori prevention interventions. Moreover, encouragement for the use of instrumental support is needed for improving hikikomori.
