Background: It is well-established that, for adolescents to adopt sustainable healthy lifestyle behaviors, not only access to information but also the skills required to translate that information into action are critical. In this field, research that examines the relationship between e-health literacy and sustainable healthy lifestyle behaviors within the context of physical literacy is notably scarce. In this context, the aim of this study is to examine the effect of e-health literacy on a sustainable healthy lifestyle and to evaluate the mediating role of physical literacy in this relationship. Methods: A total of 835 adolescents from high schools across Türkiye voluntarily participated in this study. During the data collection process, the e-Health Literacy Scale, the Perceived Physical Literacy Scale, and the Healthy and Sustainable Lifestyle Scale were utilized. Data were analyzed using the JASP (version 0.18.3.0) software. Correlation analysis and structural equation modeling were conducted, and the bootstrap method (n = 5000) was employed for mediation analysis. Results: The effect of e-health literacy on a sustainable healthy lifestyle was found to be positive and statistically significant (β = 0.452, p < 0.001). Similarly, e-health literacy significantly predicted physical literacy (β = 0.755, p < 0.001), and physical literacy significantly predicted a sustainable healthy lifestyle (β = 0.310, p < 0.001). The mediating effect was also statistically significant (β = 0.234, p < 0.001). The model explained 32% of the variance in healthy lifestyle behaviors. Conclusions: The findings indicate that evaluating e-health literacy and physical literacy together provides a holistic approach to fostering sustainable healthy lifestyle habits among adolescents. It is recommended that intervention programs be structured to encompass both areas of competence.

The purpose of this research is to develop a physical literacy scale for secondary school students. 650 students from 5th, 6th, 7th and 8th grades participated in the research. The draft form was prepared by reviewing the literature and taking expert opinions. Interviews were conducted with 40 students to test the comprehensibility of the items (the wording of 5 items was revised). As a result of the pilot reliability analysis and Bartlett's sphericity test, it was accepted that the correlation between the variables was sufficient, and the scale consisted of questions with a unique and homogeneous structure. Then, Kaiser-Meyer-Olkin, Bartlett and Cronbach Alpha values were checked, and they were determined to be suitable and sufficient for EFA. As a result of EFA, 20 items collected in 4 factors were obtained. The variance explained by these factors is 58.442%. As a result of the CFA conducted in SPSS AMOS 24 programme, 3 items that did not meet the model fit index criteria were removed. It was determined that the standardized item loadings of the 17 items that met the model fit conditions ranged between 0.654-0.895, R2 values ranged between 0.43-0.80 and standard errors ranged between 0.045-0.102. Regarding reliability, AVE, CR, and internal consistency coefficients were examined, and it was determined that they meet the specified criteria. The final version of the scale consists of four sub-dimensions ("Motivation", "Knowledge and Understanding", "Confidence" and "Physical Competence"). In conclusion, it was determined that the developed scale is a valid and reliable measurement tool for assessing students' perceptions of physical literacy.

Literatürde Türk toplumuna uyarlanarak geliştirilen sosyal medya ile ilgili ölçek çalışmaları incelendiğinde araştırmacıların genellikle sosyal medya bağımlılığı üzerine odaklandıkları görülmektedir. Sosyal medya kullanımı ile ilgili ise çok az sayıda araştırma bulunmakla birlikte sporcuların sosyal medya kullanım davranışları ile ilgi herhangi bir araştırmaya rastlanmamıştır. Bu bağlamda bu araştırmada sporcuların sosyal medya kullanım davranışlarını incelemede kullanılabilecek geçerli ve güvenilir bir ölçüm aracının geliştirilmesi amaçlanmıştır. Tarama modelinden faydalanarak tasarlanan bu araştırma 19- 35 yaş aralığında hem aktif olarak spor yapan hem de en az bir sosyal medya aracı kullanan toplam 487 bireyin katılımı ile gerçekleştirilmiştir. Ölçek maddeleri, literatür taraması ve alan uzmanları görüşleri alınarak hazırlanmıştır. Yapılan açımlayıcı faktör analizleri sonucuna göre 15 madde ve 3 alt boyuttan (içerik üretme, kullanım sıklığı ve sosyal medya bağımlılığı) oluşan bir ölçme yapısı elde edilmiştir. Bu yapı doğrulayıcı faktör analizi ile test edilmiş ve mevcut yapının geçerliği teyit edilmiştir. Ölçeğin güvenirliği, test-tekrar test yöntemi ve iç tutarlılık analizi ile incelenmiştir. Analizler, ölçeğin Cronbach Alpha iç tutarlılık katsayısının tüm alt boyutlarda 0,70 üzerinde değere sahip olduğunu göstermiştir. Bu bağlamda bu araştırmada geliştirilen ölçeğin güvenilir olduğu ve geçerli bir ölçüm aracı olarak kullanılabileceği söylenebilir.

Background: It is well established that healthy lifestyle behaviors have significant effects not only on physical health but also on psychological well-being; however, the underlying mechanisms of these effects have yet to be fully elucidated. In this context, the aim of this study is to examine the relationships between a sustainable healthy lifestyle and levels of depression, stress, and anxiety, and to test the mediating role of physical literacy in these associations. Methods: This cross-sectional study was conducted among university students in Malatya, Türkiye, and a total of 652 voluntary participants were included. In the theoretical model of the study, a sustainable healthy lifestyle was positioned as the independent variable, depression, stress, and anxiety as dependent variables, and physical literacy as the mediating variable. Data were analyzed using structural equation modeling with bootstrapping to assess mediation effects. Results: Results obtained from the structural equation modeling indicate that a sustainable healthy lifestyle has significant and protective relationships with psychological well-being. Negative and significant relationships were identified between a sustainable healthy lifestyle and levels of depression, stress, and anxiety. Furthermore, higher levels of physical literacy were associated with lower levels of these psychological symptoms, with physical literacy playing a strong mediating role in these relationships. The model results revealed that lifestyle components such as regular physical activity, balanced nutrition, and sufficient sleep enhance individuals’ physical competence and awareness. Physical literacy was also found to have a significant negative relationship with depression, stress, and anxiety. Conclusions: These results indicate that physical literacy is a key variable not only for physical functioning but also for psychological resilience and well-being. Moreover, the impact of a sustainable healthy lifestyle on psychological symptoms appears to be largely mediated through physical literacy.

The aim of this research was to examine the demographic factors that affect athletes' social media usage behaviors and understand how these factors exert influence. This cross-sectional study involved 296 athletes who participated voluntarily, and the research was conducted using a quantitative approach. A questionnaire assessing demographic information and a scale measuring social media usage behaviors were utilized. Data analysis was performed using IBM SPSS software, providing a detailed examination of how athletes' social media interactions vary based on different demographic characteristics. The findings of the study indicate that demographic factors have a significant impact on social media usage behaviors. Variables such as age, gender, and type of sport substantially influence how and for what purposes athletes use social media. The results suggest that in order to better understand social media usage behaviors, not only demographic features but also athletes' sports habits should be taken into account. These findings could also assist in developing strategies to promote more conscious and balanced use of social media among athletes.
