Purpose: The present study aims to examine the mediating role of challenge and threat between positive thinking skills and perception of excellent performance in football players competing in the regional amateur league, which is referred to as a semi-professional league in Turkey.Methods: The study population consisted of football players competing in regional amateur leagues in the 2023–2024 season, and the sample consisted of 388 athletes selected using the simple random method. In addition to the demographic information form developed by the researcher, the Positive Thinking Skills Scale, the Challenge and Threat in Sport Scale and the Performance Perfectionism Scale for Sport were applied to the participants. The data were analyzed digitally through the SPSS 25 package program. The Pearson Correlation analysis was used to determine the correlations between the variables and a regression analysis of the indirect effect approach based on the Bootstrap method through PROCESS v4.2 macro was used to determine the mediating effect of challenge and threat in the relationship between positive thinking and perception of excellent performance. PROCESS Macro Model Option 4 developed by Hayes was used to examine the mediating effect. While conducting this analysis, the 5,000 resampling option was selected in the Bootstrap method.Results: The study found that positive thinking had a positive, moderate, and statistically significant effect on the perception of challenge (a = 0.439, p < 0.01) and excellent performance (c’ = 0.484, p < 0.001), with approximately 32% of the variance in challenge explained by positive thinking (R2 = 0.319, p < 0.01). Additionally, challenge played a mediating role. Positive thinking also had a negative, moderate effect on threat (a = −0.425, p < 0.01), explaining 7% of the variance in threat (R2 = 0.070, p < 0.01). However, the threat had a negative and low-level impact on the perception of excellent performance (b = −0.244, p < 0.001).Conclusion: In conclusion, it was found that the positive thinking skills of the football players positively affected their perceptions of excellent performance, and the feelings of challenge and threat they experienced on the field played a mediating role in the relationship between these positive thinking skills and perceptions of excellent performance.

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.

Bu çalışmanın amacı amatör futbolcuların sahip oldukları sosyal güvenceleri hakkındaki farkındalıklarını araştırmaktır. Çalışmanın evrenini, Isparta ilinde amatör futbol liglerindeki takımlar bünyesinde mücadele eden 259 amatör futbolcu, örneklem grubunu ise, bu evren içinden rastgele yöntemle seçilmiş 116 sporcu oluşturmuştur. Katılımcılardan kişisel bilgi formu yanında sosyal güvenlikle ilgili farkındalık ölçeğini doldurmaları istenmiştir. Veriler, bilgisayar ortamında IBM SPSS 22.0 (Statistics for Windows) adlı program aracılığıyla analiz edilmiştir. Çoklu karşılaştırmalarda Tek Yönlü Varyans Analizi kullanılmış olup; farklılığın belirlenmesi için LSD Testi uygulanmıştır. Sonuç olarak, amatör futbolcuların sosyal güvenlikle ilgili farkındalık düzeylerinin ortalamanın altında olduğu, yaş ve eğitim durumuna göre farklılaşmazken, spor yaşı, ücret ve lig seviyesine göre farklılaştığı tespit edilmiştir. Bu durumun özellikle amatör futbolcuların sosyal güvenlikle ilgili farkındalıklarının son birkaç yıllık sürede yaygınlaşmaya başladığından kaynaklandığı düşünülmektedir.

Bu araştırmanın amacı, üniversite öğrencilerinin yaratıcılık düzeyleri ile duygu yönetim düzeyleri arasındaki ilişkinin tespit edilmesidir. Araştırmaya Bingöl Üniversitesi bünyesinde bulunan Beden Eğitimi ve Spor Yüksekokulu’nda beden eğitimi ve spor öğretmenliği bölümünde bulunan tesadüfi yöntemle seçilmiş 154 öğrenci katılmıştır. Araştırmada veri toplama araçları olarak; Raudsepp (1977) tarafından geliştirilen ve Çoban (1999) tarafından Türkçe’ye uyarlanan yaratıcılık ölçeği, Çeçen (2006) tarafından geliştirilen duyguları yönetme becerileri ve kişisel bilgi formu kullanılmıştır. Araştırmada elde edilen veriler bilgisayar ortamında analiz edilmiştir. Kişisel bilgi formu, yaratıcılık ve duygu yönetim düzeyleri ölçeğinden elde edilen veriler analizleri bilgisayar ortamında yapılmıştır. Sonuç olarak, üniversite öğrencilerinin yaratıcılık düzeylerinin ortalamanın altında, duyguları yönetme becerileri ölçeği alt başlıklarının ve toplam puanın ortalamanın üstünde olduğu tespit edilmiştir. Ayrıca, yaratıcılık düzeyleri ile duyguları yönetme becerileri alt başlıklarından başa çıkma arasında pozitif yönde düşük düzeyde ilişki tespit edilmiştir. Bu durumun, çalışmamıza katılan öğrencilerinin sportif geçmişleri sayesinde kazandıkları tecrübelerle, bedensel tepkileri kontrol, sinir ile baş edebilmeleri açısından, duygularını doğru bir şekilde düzenleyebilmeleri ve karşılaştıkları sıkıntıların da çözümünde başa çıkma becerilerini bu sportif tecrübelerin gelişmiş olmasından kaynaklandığı düşünülmektedir.

The aim of this study is to measure the nomophobia levels of high school students studying in the city center of Uşak and to examine the relationship between personality traits and nomophobia levels. The population of the study consists of high school students in Uşak city center, Turkey, while the sample group includes 200 high school students selected through a simple random sampling method from science high schools, teacher high schools, Anatolian high schools, and vocational high schools. The research was conducted using the survey model, one of the quantitative research methods. A personal information form, a nomophobia scale to measure technological addiction, and a ten-item personality scale to assess personality traits were utilized. To analyze the data, independent samples t-tests, parametric one-way analysis of variance (ANOVA), and the Tukey test for intergroup differences were applied. The findings indicate a statistically significant and inverse relationship between the "losing online connection" sub-dimension of the nomophobia scale (TNS) and both the "extraversion" sub-dimension and the overall score of the ten-item personality scale (TIPS). However, no statistically significant relationships were found for the other sub-dimensions of the TNS and TIPS. Additionally, no significant associations were identified between the subscales of the TNS and TIPS or between the overall TIPS score and the subscales of the TNS. The results of the study revealed that women exhibited higher levels of nomophobia than men, and that increased daily mobile internet and smartphone usage were associated with higher nomophobia levels. Furthermore, individuals who engaged in sports demonstrated higher scores in "agreeableness" and "emotional stability." It was also found that individuals' anxiety about "losing online connection" was inversely related to extraversion. However, variables such as phone usage duration, years of mobile internet usage, and time spent with friends during the day did not have a significant effect on personality traits or nomophobia levels.

Background: This study aims to examine the relationship between Kinesiophobia and Rumination in athletes, and to reveal the mediating roles of Coping Responses and Psychological Flexibility in this relationship. Methods: Three hundred ninety licensed athletes, including 225 females and 165 males, voluntarily participated in the study. Participants were selected through simple random sampling from various sports clubs across Turkey. During the data collection, participants were contacted online. They completed the personal ınformation form, the Tampa Scale of Kinesiophobia, the Sport Competition Rumination Scale, the Psychological Flexibility Scale, and the Coping Responses Inventory. IBM SPSS 26 and PROCESS Macro Model 4.0 were used for data analysis. In addition to descriptive statistics, Pearson correlation, linear regression, and mediation analyses were conducted. The adequacy of the sample size was evaluated using G*Power (v 3.1). The Bootstrap method with 5000 resamples and a 95% confidence interval was applied in the mediation analysis. Results: The study’s findings indicated that kinesiophobia significantly predicted levels of rumination among athletes, and that both psychological flexibility and coping responses partially mediated this relationship. Although both variables were functional in reducing ruminative thinking, coping responses demonstrated a more potent effect. The results suggest that the tendency to avoid movement affects physical and cognitive processes. Conclusions: It was concluded that psychological flexibility and coping responses are protective factors in reducing repetitive negative thought patterns in athletes. In this regard, it is recommended that holistic intervention programs aimed at enhancing psychological resilience be developed to support mental health and athletic performance.
