The aim of this study was to validate the Tampa Scale of Kinesiophobia for
Parkinson's disease (TSK-PD). This was a cross-sectional evaluation of the
psychometric properties of an adapted questionnaire. The psychometric testing
included confirmatory factor analysis, reliability by internal consistency
(Cronbach's alpha) and test-retest reliability (intraclass correlation
coefficient), construct validity by comparing TSK-PD with the Falls Efficacy
Scale-International (FES-I), the Movement Disorder Society - Unified Parkinson's
Disease Rating Scale (MDS-UPDRS), the Hospital Anxiety and Depression Score
(HADS) and the Short-Form Health Survey (SF-36) (Pearson's correlations), and
sensitivity to change by calculating the smallest detectable change. The
questionnaire was administered to 132 patients with Parkinson's disease. Factor
analysis confirmed a two-factor (harm and activity avoidance), 13-item solution,
which led to an acceptable data-model fit. Internal consistency (alpha=0.94) and
test-retest reliability (intraclass correlation coefficient, model 2.1=0.90) were
good. Construct validity showed a close correlation between the TSK-PD and FES-I
(r=-0.710); a moderate correlation with the MDS-UPDRS (r=0.513); moderate to
close correlations with HADS-D (r=0.443) and HADS-A (r=0.626); moderate
correlations with the mental subscales of the SF-36 (r=-0.327 to -0.563); and
poor correlations with the physical subscales of the SF-36 (r=-0.236 to -0.248).
The smallest detectable change was 11. The TSK-PD had a good factorial structure
and satisfactory psychometric properties. Its use is recommended for clinical and
research purposes.
