Background: Physical activity (PA) provides significant health benefits, yet inactivity remains high in Spain, especially among adolescents and increasingly in children. Identifying barriers to PA is essential, but available tools are mainly designed for adolescents. This study aimed to adapt the "Brief Scale of Perceived Barriers to Physical Activity" for Spanish schoolchildren aged 6-12 and examine its validity and reliability. Methods: The "Brief Scale of Perceived Barriers to Physical Activity for Children" was linguistically and culturally adapted. Comprehension was assessed through cognitive interviews, and reliability was examined via a test-retest procedure with 137 Spanish schoolchildren. Several analyses were conducted, including confirmatory factor analysis (CFA) to assess the factor structure, along with reliability metrics: Cronbach's alpha (a) for internal consistency and the intraclass correlation coefficient (ICC) for test-retest reliability. Results: CFA confirmed a four-factor structure (self-concept, motivation-interest, social support, and task incompatibility) in a sample of 137 with excellent fit indices (?(2)/df = 1.394, RMSEA = 0.054, CFI = 0.976, TLI = 0.966). Internal consistency ranged from good to excellent (a = 0.831-0.979). Temporal stability was substantial to near perfect (ICC = 0.708-0.979). Measurement error was low for all items and the total score (SEM% = 6.1-37.2; MDC% = 17.0-103.0), demonstrating accuracy. Conclusions: The "Brief Scale of Perceived Barriers to Physical Activity for Children" was proven to be a reliable and valid tool for assessing perceived barriers to PA in Spanish children. It offers developmentally appropriate insights that can guide strategies to enhance supportive environments and promote long-term active behaviours. As part of the social domain, it contributes to the Spanish Physical Literacy Assessment for Children (SPLA-C) model, the first physical literacy (PL) assessment instrument developed in Spain.
