Análises das propriedades de medida das escalas tampa para cinesiofobia com 17 e 11 itens em indivíduos com osteoartrite de joelho

Abstract

Objective: To evaluate the validity of the 17-item and 11-item Tampa Scales for Kinesiophobia in individuals with knee osteoarthritis (KOA). Methods: This methodological study focused on assessing measurement properties of a Patient Reported Outcome Measure (PROM). The study was conducted following the Guidelines for the Process of Cross-cultural Adaptation of Self-Report Measures and Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN). One hundred individuals participated in construct and criterion validity analyses, as well as in the assessment of ceiling and floor effects. A subsample comprising the last fifty evaluated participants completed the reproducibility testing for test-retest reliability. Construct validity was evaluated by correlating scores from the Tampa Scales for Kinesiophobia with the Pain Catastrophizing Scale (PCS) and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), 12-item version. Results: The 17-item TSK showed correlations with the PCS domains of magnification and helplessness, classified as weak and moderate, respectively. Internal consistency was deemed inadequate. Test-retest reliability (ICC2,1) was classified as excellent, and the percentage of EPM was considered very good. The 11-item TSK showed correlations with the PCS domains of magnification, rumination, and helplessness, classified as moderate, weak, and moderate, respectively. Internal consistency was also classified as inadequate. Criterion validity was considered good. Test-retest reliability for the 11-item TSK showed an ICC2, 1 classified as substantial, with the EPM percentage also classified as very good. Conclusion: The 11-item and 17-item versions of the TSK demonstrate adequate construct and criterion validity as well as test-retest reliability. However, both versions exhibit inadequate internal consistency.
