Exploring the Psychometric Properties of the Disablement in the Physically Active Scale Short Form-8 in Adolescents

Context : Patient-reported outcomes are widely used in health care. The Disablement the Physically Active (DPA) Scale Short Form-8 (SF-8) was recently proposed as a valid scale for physically active population. However, further psychometric testing of DPA SF-8 has not been completed, and structure assessed using sample adolescent athletes. Objective To assess high-school Main Outcome Measure(s) Adolescent athletes (n = 289) completed SF-8. Confirmatory factor analysis (CFA) conducted to properties scale. Results CFA indicated that model exceeded recommended fit indices (Comparative Fit Index .976, Tucker–Lewis .965, Root Mean Square Error Approximation .061, Bollen’s Incremental .976). All loadings were significant ranged from .62 .86. Modification did suggest meaningful cross-loadings present or additional specifications could maximize parsimony. Conclusions met contemporary recommendations athlete results confirmed initial findings supporting well uniqueness quality-of-life physical summary factors an Further research (eg, reliability, invariance between groups, minimal clinically important differences, etc) is warranted inform use clinical practice research.
