The Exercise Benefits/Barriers Scale (EBBS) research instrument has been extensively used to investigate the perceived benefits and barriers of exercise in a range settings. In order examine theoretical contentions translate findings, it is imperative implement measurement tools that operationalize constructs an accurate reliable way. original validation EBBS proposed nine-factor structure for tool, examined factor structure, suggested various factors are important testing perception barriers, whereas few items may not be vital. current study conducted confirmatory analysis (CFA) using hierarchical 565 participants from northwest region United Kingdom, results which provided evidence four-factor measure, with Comparative Fit Index (CFI) = 0.943, Tucker–Lewis (TLI) 0.933, root means square error approximation (RMSEA) 0.051, namely life enhancement, physical performance, psychological outlook, social interaction, as well two-factor barrier measures, CFI 0.953, TLI 0.931, RMSEA 0.063, including milieu time expenditure. Our findings showed six-factor correlated model, 0.930, 0.919, 0.046. multi-group CFA support gender invariance. indicated after three decades EBBS, many core still relevant assessment higher-order factors; however, 26-item concise tool displays better parsimony comparison 43-item questionnaire. Overall, provides reliable, cross-culturally valid within UK adult population, proposes shorter more version compared gives direction future focus on content validity assessing activity.
