    (Frontiers Media Sa, 2023) Melguizo-Ibanez, Eduardo; Gonzalez-Valero, Gabriel; Badicu, Georgian; Yagin, Fatma Hilal; Alonso-Vargas, Jose Manuel; Ardigo, Luca Paolo; Puertas-Molero, Pilar
    IntroductionScientific literature has now demonstrated the benefits of an active lifestyle for people's psychological health. Based on the above statement, the aim was to (a) evaluate and adjust a structural equation model containing the variables anxiety, self-concept, and Mediterranean diet adherence and (b) contrast the proposed theoretical model by studying the differences between the variables according to the level of weekly physical activity in a sample of 558 university students. MethodsA non-experimental, exploratory, cross-sectional investigation has been proposed. Instruments such as the PREDIMED Questionnaire, the Beck Anxiety Inventory, the International Physical Activity Questionnaire, and the Form 5 Self-Concept Questionnaire were used to collect data. Results and discussionThe results illustrate that students showing low adherence to the Mediterranean diet had higher levels of anxiety (M = 0.95) than those showing a high degree of adherence (M = 0.75). It is also observed that young people with a high degree of adherence to the Mediterranean diet report higher scores in the different dimensions of self-concept compared to young people with a low degree of adherence. In conclusion, it is affirmed that young people who show a high degree of adherence to this dietary pattern show lower levels of anxiety and greater recognition of the different areas of their self-concept.

    Relationship between motivational climate, anxiety and average mark in pre-service physical education teachers: a cross-sectional study based on structural equation modelling approach
    (Bmc, 2025) Melguizo-Ibanez, Eduardo; Gonzalez-Valero, Gabriel; Badicu, Georgian; Yagin, Fatma Hilal; Alonso-Vargas, Jose Manuel; Ardigo, Luca Paolo; Puertas-Molero, Pilar
    BackgroundMotivation is a variable that directly influences task orientation. Within the motivational sphere, the motivational climate determines whether a task is performed with an intrinsic or extrinsic.PurposeIt has been observed that depending on motivational orientations, anxiety levels and task performance can be increased. Likewise, there are differences in interests depending on the gender of individuals.MethodsThis research aims (a) To elaborate and adjust a theoretical model of the causal relationship of motivational climate on anxiety and academic performance and (b) To analyse the causal relationship between the motivational climate on anxiety and the average mark of the participants. Regarding the design, a comparative, cross-sectional and descriptive study was carried out on a sample of 558 trainee physical education teachers. The sample for this study is from southern Spain. Likewise, the branch of study of the sample is related to university degrees in education sciences and physical activity and sport sciences. The Beck Anxiety Inventory (BAI), Perceived Motivational Climate in Sport-2 and an ad hoc socio-demographic questionnaire were used to collect the data.ResultsIt is observed that the male sex presents a greater causal relationship of task climate (beta=-0.259; p <= 0.05) and ego climate (beta = 0.324; p <= 0.001) on anxiety. A stronger causal relationship of task climate (beta = 0.340; p <= 0.001) and ego climate (beta = 0.241; p <= 0.05) on mean score is also observed for the male population. The sample presents a negative causal relationship of anxiety on the average mark. This is higher for the male population (beta=-0.126).ConclusionsMale students show a greater causal effect of motivational climate on anxiety and grade point average. Likewise, the causal relationship of task climate on the development of anxiety is negative for the study sample. In contrast, the ego climate exerts a positive causal relationship on the development of anxiety.
