Determinadas variables psicológicas y la personalidad son consideradas como factores predisponentes o influyentes para el posterior desarrollo de los trastornos de la conducta alimentaria, así como también la puesta en práctica de determinados comportamientos de riesgo, como los atracones, vómitos o la práctica de ejercicio físico excesivo para la pérdida de peso. El objetivo del estudio fue comparar las diferencias en personalidad y variables psicológicas relevantes relacionadas con los TCA, en mujeres y hombres, a partir del cumplimiento de criterios específicos a partir de los cuales se recomienda la derivación a un especialista en patologías alimentarias. En el estudio participaron 604 estudiantes universitarios, y se emplearon el Inventario de Trastornos de la Conducta Alimentaria (EDI-3) y su cuestionario de remisión (EDI-3 RF), y el Five-Factor Inventory (NEO-FFI). Los resultados mostraron que hasta el 58.5% de mujeres y 49.5% de hombres cumplen criterios de remisión. Tanto en mujeres como en hombres, existen diferencias entre los grupos con criterios y quienes no los presentan, principalmente en neuroticismo, obsesión por la delgadez, bulimia, insatisfacción corporal y ascetismo. Las puntuaciones en el factor neuroticismo y en la gran mayoría de escalas psicológicas son también superiores en los sujetos que cumplen con mayor número de criterios. Certain psychological variables and personality are considered as predisposing or influential factors for the subsequent development of eating disorders. Also the implementation of some risk behaviors, such as binge eating, vomiting or excessive physical exercise for weight loss. The objective of the study was to compare the differences in personality and relevant psychological variables related to eating disorders, in women and men, based on compliance with specific criteria to help identify individuals with potential eating disorders. Participants were 604 university students. The Eating Disorder Inventory-3 (EDI-3) and referral form (EDI-3 RF), and the Five-Factor Inventory (NEO-FFI) were used. The results showed that up to 58.5% of women and 49.5% of men met remission criteria. In both women and men, there are differences between groups with criteria and those who do not, mainly in neuroticism, drive for thinness, bulimia, body dissatisfaction and asceticism. The scores in the neuroticism factor and in the great majority of psychological scales are also higher in the subjects that accomplish the highest number of criteria.

Adolescence is a period of special significance for the development of personal and social values. Positive adolescent development (PYD) can be an ideal perspective from which to promote values in young people through their sports practice. The aim of the study was to adapt and analyse the measurement properties of the Values Scale for Positive Youth Development for use in the context of sport in young athletes. A total of 599 adolescents, competitors of different sports modalities, participated in the study. Confirmatory factor analysis and reliability and invariance analyses were performed. The results confirmed a good model fit, with adjustment indexes (CFI, GFI and AGFI) above 0.90 and error (RMSEA and SRMR) below 0.08. The factor loadings above 0.50 were obtained for all items. Adequate reliability of the scales was also confirmed, between 0.72 and 0.89, and gender, age and sport invariance were confirmed. In conclusion, the analysed scale is a valid and reliable instrument with adequate psychometric properties, which makes it an appropriate assessment tool to be used in sports contexts, based on the positive adolescent development approach.

Eating disorders (EDs) have been understudied and misunderstood in men. Among the relevant factors in the risk, onset, and maintenance of EDs, personality stands out. Therefore, the aim of the study was to analyze the relationships between personality traits and risk variables for the development of EDs in men. A total of 443 male university students (mean = 22.16 years) who completed the Spanish versions of the Eating Disorder Inventory-3 (EDI-3) and the NEO Five-Factor Inventory (NEO-FFI) participated. Correlation analyses were performed, and in order to determine the predictive role of personality traits on risk scales, a hierarchical multiple regression was performed. The results showed that neuroticism was positively associated with drive for thinness, being its main predictor variable. In bulimia, the main relationships were positively associated with neuroticism and negatively with conscientiousness. As for body dissatisfaction, the main predictor variables were neuroticism and, in a negative sense, extraversion and openness to experience. In conclusion, personality traits are related to the risk of developing EDs in male university students, with neuroticism being the main associated trait.

Background: Emotion regulation refers to the processes through which individuals influence their emotional experiences, including how emotions are generated, experienced, and expressed. Difficulties in emotion regulation have been identified as a relevant factor in the development and maintenance of Eating Disorders (EDs). In the sports context, high physical and performance demands may intensify emotional challenges, potentially increasing vulnerability to eating disorder symptomatology among athletes. Objectives: This systematic review aimed to examine the relationship between emotion regulation and EDs in athletic populations, with a particular focus on emotion regulation strategies and related emotional processes. Methods: The PICO model was used, and PRISMA guidelines were followed. The Redalyc, Dialnet, SpringerLink, and PubMed databases were searched from inception to April 2025, with an update in November 2025. After the selection process, nine studies involving athletes from different disciplines and competitive levels were included. Methodological quality and risk of bias were assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklists. Results: The findings indicate that adaptive emotion regulation strategies, such as Cognitive Reappraisal and emotional identification, are associated with lower levels of eating disorder symptomatology, body dissatisfaction, and greater resilience to sport-related pressures. In contrast, dysfunctional strategies, including expressive suppression, emotional unawareness, and difficulties in emotion management, were consistently associated with restrictive eating behaviors, bulimic symptomatology, excessive weight control, and increased ED risk. Additional emotional factors, including anxiety, perfectionism, low self-esteem, and body image dissatisfaction, were also related to higher vulnerability to EDs, particularly in sports with high aesthetic or weight-related demands. Conclusions: Emotional regulation is closely associated with ED risk in athletes. Adaptive emotion regulation strategies may serve as protective factors, whereas dysfunctional strategies are associated with increased risk.

Eating Disorders (EDs) are more prevalent among athletes due to performance pressure and body ideals. Emotional regulation is a key factor in ED. This study aimed to (1) examine the reliability and structural validity of the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA) in adolescent Mexican athletes, and (2) analyze associations between emotional regulation strategies (expressive suppression and cognitive reappraisal) and ED risk factors (drive for thinness, body dissatisfaction, and bulimia). An instrumental, cross-sectional design was employed with 295 Mexican athletes (Mage = 16.85, SD = 3.27). The ERQ-CA demonstrated good psychometric properties, with acceptable reliability (ω > 0.70) and excellent fit for the two-factor model (CFI = 0.995, RMSEA = 0.018). Emotional suppression was positively associated with all ED risk indicators, whereas cognitive reappraisal was negatively associated. These findings highlight that individual differences in emotion regulation are linked to ED risk in adolescent athletes. Monitoring expressive suppression and promoting cognitive reappraisal may serve as supportive strategies for coaches, parents, and mental health professionals, enhancing emotional flexibility and potentially reducing ED risk.
