Validity and Reliability of the Tampa Scale for Kinesiophobia for Adolescents with Heart Disease.

Abstract

To assess the validity and reliability of a newly adapted Tampa Scale for KP for adolescents with HD (TSK-Heart-A). The TSK-Heart-A survey consists of 17 Likert scale items, producing a summary score (SS) ranging from 17 (low KP) to 68 (high KP). Following content and face validity, adolescents (age 12-18 yr) with arrhythmia disorders or Fontan palliation were recruited. The PROMIS pediatric anxiety and depression short forms, Pediatric Quality of Life Inventory (PedsQL) generic core and cardiac module, and a PA questionnaire for adolescents (PAQ-A) were used for criterion validity. The TSK-Heart-A was completed twice (20.4 ± 6.3 days apart) for assessment of internal and test-retest reliability. Pearson correlations and Cronbach's alpha determined validity and reliability, respectively. Adolescents ( n = 63) were 15.5 ± 1.8 yrs old, 50.8% were female, and 69.8% had arrhythmia disorder. Mean TSK-Heart-A SS was 33.8 ± 7.8 (range, 20 to 56). The TSK-Heart-A SS correlated significantly with PROMIS T-scores (anxiety: 49.7 ± 12.2, r = 0.48; depression: 46.9 ± 12.7, r = 0.41), PedsQL score (generic QoL: 75.2 ± 18.9, r = -0.61; cardiac QoL: 74.7 ± 17.5, r = -0.56), and PAQ-A (score: 2.0 ± 0.7, r = -0.35). Test-retest and internal reliability had a total score of r = 0.77 ( P = 0.89). The new TSK-Heart-A survey is valid and reliable and suggests that KP is present in some adolescents with HD.
