Key Points

To establish the validity and reliability of the Turkish version of the Well-Being in Pain Questionnaire (WPQ-Tr).
Cross-cultural adaptation of WPQ-Tr for Turkish speakers
Assessment of known-groups validity with pain-free controls
Principal Component Analysis (PCA) to evaluate structure
Confirmatory Factor Analysis (CFA) to support findings
Assessment of convergent validity with other established measures.
Significant differences in WPQ-Tr scores between individuals with chronic low back pain and controls (p < 0.01)
PCA revealed a unidimensional structure explaining 54.66% of variance
Strong correlations with other measures indicating convergent validity (e.g., EQ-5D-5L ρ = 0.902, GAD-7 ρ = -0.828)

Abstract

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.
