Assessment of the Psychometric Properties of the Tampa Scale of Kinesiophobia (TSK) Questionnaire in Poland Based on Patients with Type 2 Diabetes Complicated by Stroke

<b>Background/Objectives:</b> Kinesiophobia, or the fear of movement, is a significant problem in the rehabilitation of patients after a stroke, especially in individuals with diabetes, who have an increased risk of health complications. The aim of the study was to validate the Tampa Scale for Kinesiophobia (TSK) for assessing kinesiophobia in the context of patients with diabetes complicated by stroke to ensure its adequacy and reliability in this specific group of patients. <b>Methods:</b> After considering exclusion criteria, 166 patients with type 2 diabetes after ischemic stroke, hospitalized in the neurological rehabilitation ward, were included in the analysis. A survey using the TSK was conducted in the study group. A reliability analysis of the questionnaire was conducted, and then exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to disclose the number of factors that characterize the study group. <b>Results:</b> The Cronbach's alpha value for the entire scale is 0.875. The value for all the questions on the scale was also above 0.86, so they are considered reliable. Removing any question does not increase the value of Cronbach's alpha or Guttman index. Based on the scree plot, two factors were identified. The first factor includes 12 items and forms a physical factor, while the second factor includes 5 items and forms a psychological factor. The fit of the two-factor model was checked using confirmatory factor analysis. The final two-factor model has an acceptable fit. All the factor loadings are statistically significant. The factor loadings range from 0.262 to 0.729 for the physical factor and from 0.543 to 0.822 for the psychological factor. <b>Conclusions:</b> The TSK is a reliable and valid tool for assessing the level of kinesiophobia in a group of patients with type 2 diabetes complicated by stroke. The results of the study using this tool may contribute to the development of more effective therapeutic strategies that take into account the specific physical and psychological needs of this group of patients.
