Background: Post-traumatic stress disorder (PTSD) often impairs children's and adolescents’ functioning across different life domains. Significant functional impairment is a diagnostic criterion for PTSD in both the DSM-5 and the ICD-11, but the methods in terms of domains covered and scoring rules to assess functional impairments are quite inconsistent.Objective: This systematic review evaluates instruments specifically designed to assess post-traumatic stress symptoms (PTSS), PTSS modules within diagnostic interviews, and generic functional impairment measures used to capture PTSS-related functional impairment in children and adolescents.Method: A systematic search was conducted across six databases for studies published between January 2010 and November 2025. Eligible papers included the development or psychometric evaluation of PTSS-specific measures, PTSS modules in diagnostic interview, and generic functional impairment measures validated in samples exposed to trauma or adverse childhood experiences. Data were extracted and categorized based on assessed content domains, scoring methods, and psychometric properties, with results stratified by age group (6 years and younger versus 7 years and older).Results: From 3519 records, 30 papers met the inclusion criteria. Thirteen PTSS-specific instruments, one diagnostic interview module, and one generic functional impairment measure were identified. Together, these instruments assessed 11 different life domains, although considerable variation existed in the domains covered across tools. Scoring methods also varied, with approximately half using dichotomous response formats and the remainder using multi-categorical scales. Psychometric properties of the functional impairment scales were reported in only 20.7% of publications.Conclusion: Current tools for assessing PTSS-related functional impairment in youth lack standardization. There is a critical need for well-validated instruments that comprehensively capture the presence and severity of PTSS-related functional impairment.
