Can't lift your mood or find energy lately? SDS quantifies depression
SDS (Zung 自己評価抑うつ尺度) is one of the most widely used self-rating depression tools — 20 questions over the past week. This tool handles reverse scoring automatically and interprets by standard score: < 53 normal, 53-62 mild, 63-72 moderate, ≥73 severe. Depression is common and treatable, not a weakness. Free; scored locally; if you have thoughts of harming yourself, seek help right away.

よくある質問
SDS or PHQ-9 — which?
Both are common. PHQ-9 is shorter and maps closely to diagnostic criteria; SDS is widely used in clinics with detailed items. Either works — the key is using the same one to track change.
How do raw and standard scores convert?
Standard score = raw × 1.25. This tool converts and interprets it for you. Moderate or above warrants care.
