Known-groups validity was supported by significant differences in WPQ-Tr scores between individuals with CLBP and pain-free controls (p < 0.01). PCA indicated a unidimensional structure explaining 54.66% of the variance, supported by CFA. Convergent validity was supported by strong correlations with EQ-5D-5L (ρ = 0.902), PCS (ρ = -0.923), CSI (ρ = -0.923), PSQI (ρ = -0.794), RMDQ (ρ = -0.893), and GAD-7 (ρ = -0.828) (all p < 0.01).ConclusionThe WPQ-Tr is a valid and reliable instrument for assessing well-being in Turkish-speaking individuals with CLBP.
