Fear and Avoidance of Movement in People with Chronic Pain: Psychometric Properties of the 11-Item Tampa Scale for Kinesiophobia (TSK-11).

Purpose: To determine the psychometric properties of the 11-item Tampa Scale for Kinesiophobia (TSK-11) in patients with heterogeneous chronic pain.

Methods: The study evaluated test-retest reliability (intra-class correlation coefficient), cross-sectional convergent construct validity (Pearson product-moment correlation between TSK-11 and the Pain Catastrophizing Scale [PCS] scores at admission), and sensitivity to change of the TSK-11 (area under the receiver operating characteristic [ROC] curve) in patients (n=74) with heterogeneous chronic pain. We used two data sets (retrospective, n=56; prospective, n=18).
