Background. Existing self-esteem and social-comparison instruments were developed largely within Western cultural and linguistic contexts and do not fully capture the experience of social media use among Uzbek youth. This study reports the development and full psychometric evaluation of an original Uzbek-language self-report questionnaire measuring the negative impact of social media use on self-esteem. Methods. The instrument was constructed over seven stages following established psychometric methodology. Content validity was evaluated by seven experts using the Content Validity Ratio (CVR) and the Item Content Validity Index (I-CVI). The main psychometric study was conducted with a stratified sample of 1,605 respondents aged 17–35 years. Internal consistency (Cronbach’s alpha), exploratory factor analysis (EFA), confirmatory factor analysis (CFA), test–retest reliability (n = 60, 4-week interval), split-half reliability, and convergent and discriminant validity were assessed.
