Objective: This study was conducted to investigate the effects of exercise on psychological disorders in patients receiving childhood cancer treatment. Methods: The study group consisted of patients with cancer between the ages of 9 and 17 who were treated in the Hematology–Oncology units of Erciyes University. For the sample group, children with cancer were informed about the content of the study, and 40 children with cancer agreed to participate in the study voluntarily. The volunteers were divided into two groups, control and experimental, each consisting of 20 people. For the pre-test, participants completed a socio-demographic information form, as well as the Kovacs Depression scale, Beck Anxiety Inventory, and the pediatric cancer quality of life scale for children. Volunteers in the experimental group engaged in aerobic and strength exercises for an eight-week period. The study was completed with 8 volunteers in the control group and 14 volunteers in the experimental group due to various factors, such as voluntary withdrawal, disease progression, and mortality. After this period, the volunteers were asked to complete the same scales once more as a post-test. The SPSS 22.00 statistical analysis program was used. The independent samples t-test was employed to compare the pre-test and post-test findings of the control and experimental groups, while the paired samples t-test was used for within-group evaluations. Results: In the within-group comparisons, significant differences were observed in favor of the post-test scores in the experimental group for both the anxiety scale (p < 0.05, Mean: 8.14) and the quality-of-life child form (p < 0.05, Mean: 38.14). For intergroup comparisons, significant differences were found in favor of the experimental group in terms of post-test scores of depression (p < 0.05, mean: 10.57) and anxiety scales (p < 0.05, mean: 8.14). Conclusions: It is postulated that this outcome stems from the positive effects of sports activities in helping children undergoing cancer treatment distance themselves from their psychological adversities.

Objective: This study was conducted to investigate the effects of exercise on psychological disorders in patients receiving childhood cancer treatment. Methods: The universe of the study consisted of cancer patients between the ages of 9-17 who were treated in the Hematology-Oncology units of Erciyes University. For creating a sample group, children with cancer were informed about the content of the study. 40 children with cancer agreed to participate in the study voluntarily. The volunteers were divided into two groups, control and experimental, each consisting of 20 people. As pre test, while participants were administered a socio-demographic information form, Kovacs Depression, Beck Anxiety and child form of the pediatric cancer quality of life scale. Volunteers in the experimental group engaged in aerobic and strength ex-ercises for an eight-week period. The study was completed with 8 volunteers in the control group and 14 volunteers in the experimental group due to various factors such as voluntary withdrawal, disease progression, and mortality. After this period, the volunteers were asked to apply the same scales once more as post test. The SPSS 22.00 statistical analysis program was performed. The Independent Samples t-Test was em-ployed to compare the pre-test and post-test findings of the control and experimental groups, while the Paired Samples t-Test was used for within-group evaluations. Re-sults: In intragroup comparisons, significant differences were observed in favor of the post-test scores within the experimental group for both the anxiety scale and the qual-ity of life children's form. In intergroup comparisons, significant differences were de-tected in favor of the experimental group regarding the post-test scores of depression and anxiety scales. Conclusion: It is postulated that this outcome stems from the posi-tive effects of sports activities in helping children undergoing cancer treatment to dis-tance themselves from their psychological adversities.

Objective: Competition anxiety is an important psychological factor associated with athletes’ performance and psychological functioning. However, limited evidence exists regarding the relationship between sport engagement and competition anxiety among athletes with visual impairment, particularly across different visual impairment classifications. This study aimed to examine the associations between sport engagement and cognitive and somatic competition anxiety and to determine whether these associations differed across B1, B2, and B3 classification groups competing in distinct football contexts. Because B1 athletes competed in blind football whereas B2 and B3 athletes competed in partially sighted futsal, classification group and competition format were not separable in the present design. Methods: The study employed a cross-sectional correlational design and included 226 athletes classified as B1, B2, or B3 who competed under the Turkish Blind Sports Federation during the 2025–2026 season. B1 athletes competed in blind football, whereas B2 and B3 athletes competed in partially sighted futsal. Data were collected using the Sport Engagement Scale and the Revised Competitive State Anxiety Inventory-2. Pearson correlation analysis was used to examine bivariate associations. Conditional differences in the associations across the three classification groups were examined separately for cognitive and somatic anxiety using PROCESS Macro Model 1 with 5000 bootstrap resamples, with B1 specified as the reference category. The classification groups simultaneously represented different visual-function categories and different competitive formats. Results: Sport engagement was negatively associated with cognitive anxiety (r = −0.20, p = 0.003) and somatic anxiety (r = −0.24, p < 0.001). For cognitive anxiety, the moderation model was statistically significant (R² = 0.426, F(5, 220) = 32.64, p < 0.001). The Sport Engagement × B2 (B = 0.684, p < 0.001) and Sport Engagement × B3 (B = 0.843, p < 0.001) interactions were significant. The conditional association was clearly negative among B1 athletes (B = −0.859, p < 0.001), whereas the corresponding estimates for B2 and B3 were weaker and their confidence intervals included zero. A similar pattern emerged for somatic anxiety. The moderation model was significant (R² = 0.412, F(5, 220) = 30.79, p < 0.001), with significant Sport Engagement × B2 (B = 0.650, p < 0.001) and Sport Engagement × B3 (B = 0.678, p < 0.001) interactions. The conditional association was clearly negative among B1 athletes (B = −0.792, p < 0.001), whereas the estimates for B2 and B3 were weaker and less precise, with confidence intervals including zero. Conclusion: The associations between sport engagement and cognitive and somatic competition anxiety differed across the B1, B2, and B3 groups competing in distinct football contexts. Higher sport engagement was associated with lower cognitive and somatic anxiety overall, with the strongest and most precise negative estimates observed among B1 blind football players. Because classification group was inherently linked to competition format in the present sample, these differences should be interpreted as group-specific patterns arising within distinct sensory and competitive contexts rather than as effects attributable specifically to visual impairment classification or visual function. From an applied perspective, psychological preparation and pre-competition monitoring should therefore consider the combined sensory and competitive demands characterizing blind football and partially sighted futsal.
