適応障害

• 読み: てきおうしょうがい
• ローマ字: tekiō shōgai
• 漢字の分解: 適応 (adaptation; 適 = suitable + 応 = respond) + 障害 (disorder; 障 = obstacle + 害 = harm) → adjustment disorder
• 発音: /te.ki.oː.ɕoː.ɡa.i/

意味

Adjustment disorder — psychological distress caused by difficulty adapting to major life changes like a new job or relocation.

適応障害 gained widespread public awareness in Japan when several celebrities and public figures disclosed their diagnoses. Unlike うつ病 (major depression), 適応障害 is understood as being tied to specific stressors — a new workplace, a move, a relationship change — and is expected to improve when the stressor is removed. This distinction has made it easier for some Japanese people to seek help, as it feels less stigmatized than a depression diagnosis. It is particularly associated with workplace changes and is commonly discussed around April, when Japan's fiscal year begins and mass job transfers occur.

1. 転職してすぐ適応障害って診断されて、しばらく休職してた。
