    Physical activity is key to overall well-being, but the barriers to participation differ by age and context. This systematic review aimed to identify and evaluate the psychometric properties of questionnaires assessing barriers to physical activity across different age groups and to analyze their cross-cultural adaptation processes. A systematic review was conducted following PRISMA and COSMIN guidelines, searching three electronic databases up to February 2025. Measurement properties were classified as sufficient, insufficient, inconsistent, or indeterminate, and the quality of evidence was assessed using the COSMIN-modified GRADE approach. A total of 39 studies evaluating 23 different questionnaires were included. Seven instruments targeted children and adolescents, seven focused on adults, three on older adults, and five covered wider age ranges. Structural validity and internal consistency were the most frequently assessed properties, while responsiveness and criterion validity were rarely evaluated. Overall, 55% of the measurement property results were rated as sufficient, and 77% of methodological quality ratings were high. Although various questionnaires are available to assess barriers to physical activity, their psychometric properties and cross-cultural adaptation processes remain insufficiently explored, particularly in adults and older adults. This review highlights the need for further validation of existing instruments and the development of culturally sensitive tools with strong methodological rigour to improve research and public health interventions promoting physical activity.
