Background: The word hikikomori, the abnormal avoidance of social contact, has become increasingly well-known. However, a definition of this phenomenon has not been discussed thoroughly. The aim of this study is to gain a better understanding of the perception of hikikomori amongst health-related students and professionals and to explore possible psychiatric conditions underlying hikikomori.Methods: A total of 1,038 subjects were requested to complete a questionnaire regarding hikikomori phenomenon.Results: While some differences in the perception of hikikomori do exist, all subjects tended to disagree with the statement, " hikikomori is NOT a disorder" . Regarding the underlying psychiatric disorders of hikikomori, approximately 30% of psychiatrists chose schizophrenia as the most applicable ICD-10 diagnosis for hikikomori, whereas 50% of pediatricians chose neurotic or stress-related disorders.Conclusions: An argument still exists regarding the relationship between hikikomori and psychiatric disorders. We propose that the term hikikomori could be used to describe severe social withdrawal in the setting of a number of psychiatric disorders. © 2012 Tateno et al.; licensee BioMed Central Ltd.
