The aim of this study was to create a Polish adaptation of the Tampa Scale of Kinesiophobia considering fatigue, and to verify the usefulness of the scale in the context of pain in cancer patients. The study was conducted at the Breast Cancer Unit, operating at the Greater Poland Cancer Centre, and at the Poznan Centre for Specialist Medical Services in Poznan. After considering the exclusion criteria, 100 people qualified for the interviews for the final study: 50 breast cancer patients and 50 healthy respondents (without cancer). Statistical analysis of the CFA score showed that the chi-square test was not significant (χ2 = 10.243, p = 0.332), indicating an acceptable fit of items across scales. The reliability of the internal consistency of the scales was tested by examining the Cronbach's alpha scores for each question/statement. The mean values for this indicator were 0.74 for the pain-related scale and 0.84 for the fatigue-related scale. Construct validity was confirmed for the scales; AVE for the pain-related scale was 0.64 and for the fatigue-related scale was 0.68. The results suggest the validity of examining kinesiophobia in the context of pain- and fatigue-related mobility anxiety among breast cancer patients in Poland, and that the Tampa Scale of Kinesiophobia can be adapted for different dimensions of the condition. Both versions of the scale demonstrated adequately prepared parametric constructs, and all correlations showed a statistically significant relationship (p < 0.05). The use of the Tampa Scale of Kinesiophobia in oncology patient studies in Poland may ultimately improve rehabilitation programs and enable the development of strategies to assist patients in supporting treatment to reduce movement anxiety.
