The construct validity of the TSK was examined in a random general population sample of 4,884 18- to 72-year olds with pain within the past 4 weeks. Examination of construct validity adhered to the COSMIN checklist.

Five different models of the TSK were tested in the confirmatory factor analysis. While none were excellent fits, both one- and two-factor models of the TSK-13 and TSK-11 were acceptable. Two-factor models marginally outperformed one-factor models on goodness of fit. There was no association between TSK scores and muscular fitness or self-reported physical activity.
