The authors would like to draw the reader’s attention to errors in the following article:
Teo AR, Chen JI, Kubo H, Katsuki R, Sato‐Kasai M, Shimokawa N, Hayakawa K, Umene‐Nakano W, Aikens JE, Kanba S, Kato TA. Development and validation of the 25‐item Hikikomori Questionnaire (HQ‐25). Psychiatry Clin. Neurosci. 2018; 72: 780–788.
In Table 1 on page 784, a dagger symbol should have been added at the end of “I rarely spend time alone.” to read “I rarely spend time alone.†”. Also, the table note should have read as “All items were rated on a scale ranging from 0 (strongly disagree) to 4 (strongly agree). †Item was reverse‐scored.”.
In Table 3 on page 786, a dagger symbol should have been added on number 22 to read “22† I rarely spend time alone.”.
In Table S3 (Supporting Information), a dagger symbol should have been added on number 4, 7, 10, 15, 21, 22, 25. Also, the table note should have been added to read “得点範囲は 0‐100. †逆転項目”.
The authors apologize for the errors and any inconvenience they may have caused.
