In 2018, Alan Teo and colleagues published the Hikikomori Questionnaire (HQ-25) to screen for severe social withdrawal patterns first described in Japanese clinical literature. The instrument measures social isolation, home-bound behavior, and functioning impairment over months rather than days. Research on hikikomori has since expanded internationally, with studies noting overlap between withdrawal, depression, and social anxiety cited by the National Institute of Mental Health on social connection and health.

The Quiz Hub built this hikikomori test as a plain-language screener inspired by HQ-25 themes. It uses 25 original frequency items across social withdrawal, home confinement, and functional impairment rather than the full published scale. We treat hikikomori as a severe withdrawal pattern, not a joke or insult. For perceived lack of connection when you do want contact, take our loneliness test. For low mood and anhedonia over two weeks, try our depression test. For broader wellbeing across mood, anxiety, sleep, and functioning, see our mental health test.

Sample item: rating Often on avoiding meeting people raises your social withdrawal bar. Rating Nearly always on spending most waking hours indoors raises home confinement. Chronic illness, remote work, and caregiving can increase home time without reflecting hikikomori.
