I led development of the 25-Item Hikikomori Questionnaire (HQ-25) with colleagues in the United States and Japan, particularly Dr. Takahiro Kato of Kyushu University. It is a self‐administered questionnaire used to assess hikikomori, a form of severe social withdrawal and an emerging mental health issue.

 

The HQ-25 is scored between 0-100, with higher scores representing more severe symptoms of hikikomori. Forty-four (44) is a proposed cutoff score indicating risk for hikikomori. The HQ-25 consists of three factors: lack of sociality, isolation, and lack of emotional support. This measure has only been validated as a way to assess severity of hikikomori symptoms over the past 6 months. Other uses have not been validated.
