What this trial studies
This observational study evaluates the psychometric properties of Uzbek-language ADAM, AMS, and IPSS questionnaires in men aged 35-59 in the Andijan region. Participants complete the surveys electronically, with a subset repeating the assessments after 7-14 days to measure test-retest reliability. Blood samples will be collected to explore relationships between testosterone levels and questionnaire outcomes. The study will analyze construct validity, internal consistency, factor structure, and screening accuracy against testosterone thresholds, without any therapeutic intervention. Approximate enrollment is 400 men, with at least 350 complete datasets expected for analysis.
Why it matters
Potential benefit: If successful, the Uzbek versions could provide reliable tools for screening and monitoring men's health symptoms in Uzbekistan.
How similar studies have gone: Previous translation and validation efforts showed promise in other languages, but this specific Uzbek-language validation is novel for these instruments.
