MethodsAssessment was made at three time points: baseline (n=130) and 15 days (n=54) and eight weeks after baseline (n=51). Data collected at baseline were used to assess internal consistency, criterion and construct validity, and ceiling and floor effects. Data collected at baseline and 15 days after baseline were used to assess reliability and measurement error, and data collected before and after an eight-week exercise-based physical therapy intervention were used to assess interpretability of change scores. ResultsThe Tampa Scale for Kinesiophobia-11 showed adequate internal consistency (Cronbach's alpha=0.77; alpha if item deleted: 0.74–0.77), substantial reliability (intraclass correlation coefficient2,1=0.85; 95% confidence interval: 0.75, 0.90), good measurement error (standard error of measurement: 2.65 points), and a minimal detectable change (90% confidence) of 6.16 points. For validity, the Tampa Scale for Kinesiophobia-11 showed a positive and good correlation with the original Tampa Scale for Kinesiophobia (r=0.84, p<0.01), positive and moderate correlation with the Pain Catastrophizing Scale (r=0.55, p<0.01), positive and weak correlation with the Numerical Pain Rating Scale (r=0.25, p<0.01), positive and moderate correlation with the Beck Depression Inventory (r=0.39, p<0.01), and no correlation with the Patient-Specific Functional Scale (r=0.11, p=0.23). Kinesiophobia, pain, function, catastrophizing, and depression statistically improved after the eight-week intervention (p<0.01). ConclusionThe Tampa Scale for Kinesiophobia-11 is consistent, reliable, and appropriate to assess fear of movement in patients with fibromyalgia in the clinical context. Responsiveness of the Tampa Scale for Kinesiophobia-11 should be tested in future studies. ER -
