The aging males' symptoms scale for Japanese men: reliability and applicability of the Japanese version.

We aimed to confirm the reliability of the Japanese version of the Aging Males' Symptoms rating scale (JPN-AMS) and its applicability in patients with testosterone deficiency syndrome (TDS)-like symptoms, comparing it for young, middle-aged and elderly Japanese men. The study included 93 patients with TDS-like symptoms, 39 men younger than 30 years old, and 125 normal men 40 years old and older, who agreed to respond to a self-administered questionnaire using the JPN-AMS. Testing-retesting was done to confirm the reliability of the questionnaire, with a 2-week interval between tests. The total AMS score and three domain scores were clearly higher in patients with TDS-like symptoms than in young men and in normal males, respectively. The test-retest analysis showed good reliability and internal consistency for the JPN-AMS. The JPN-AMS can be reliably used for measuring health-related quality of life of aging Japanese males.
