Prolonged Social Withdrawal During Adolescence: Transdiagnostic Syndrome or a New Psychiatric Entity?

The Japanese term Hikikomori is used to describe a clinical condition in which young people present a prolonged social withdrawal and isolation. Hikikomori syndrome represents an emergent worldwide phenomenon but is still poorly reported and often misdiagnosed. This study investigates and describes an Italian hikikomori adolescent group. Socio-demographic and psychopathological profiles and the relationship between hikikomori and psychopathological conditions were analyzed. No gender difference, a medium–high intellectual level, and no correlation with socioeconomic status were highlighted among the clinical group. The relationship between social withdrawal and social anxiety was significant while no correlation was found with depressive symptoms. The presence of Hikikomori syndrome was also significant in Italian adolescents, suggesting that hikikomori is not a culture-bound syndrome related to the Japanese cultural context, but rather a syndrome occurring in the upper-medium class.
