The burnout syndrome is a negative experience for athlete development and it has been demonstrated that it gets worse when a sport is practiced in an obsessive way. Interventions with a positive view towards sports could be a protective factor to boost the athlete’s wellbeing. The aim of the present study was to analyse the mediator effect from social support, the relationship between the burnout, positivity and passion in young Mexican athletes. The sample was composed by 452 Mexican athletes, males and females (women 45%), from 12 to 18 years of age (M = 16.29, SD = 1.66). Participants answered the Athlete Burnout Questionnaire, The Scale of the Social Support Perceived by Athletes, the Passion Scale and the Positivity Scale. The results of structural equation modeling showed a good adjustment model (χ² = 889.213; df = 274; χ²/df = 3.245; p ˂ 0.01; CFI = 0.93; TLI = 0.91; IFI = 0.94; NFI = 0.91; RMSEA = 0.07). The harmonious passion presented direct and indirect effects on the burnout, being the perceived social support the mediator variable of the indirect effect. The positivity resulted positive predictor from the social support (β = 0.714, p ˂ 0.001) and social support predicted the burnout (β = −0.270, p ˂ 0.005). The obsessive passion had a direct effect over burnout (β = 0.627, p ˂ 0.001). Developing negative commitments to sports could be an indicator of a greater risk of experiencing individual conflicts that lead to sports burnout.

El Athlete Burnout Questionnaire (ABQ) se ha convertido en el instrumento más utilizado para evaluar el burnout en el contexto deportivo, lo que ha permitido un incremento significativo en las investigaciones. A pesar de ello, una revisión en la literatura revela que no existen trabajos que proporcionen datos psicométricos del ABQ con muestra mexicana, por lo que el objetivo de la presente investigación fue analizar las propiedades psicométricas del Athlete Burnout Questionnaire en deportistas mexicanos. El análisis de los datos se desarrolló a través de 2 estudios, aplicando el cuestionario en el primero de ellos a una muestra de 464 jóvenes deportistas entre 13 y 18 años de edad (M = 14.85, DT = 1.45). Los resultados del Análisis Factorial Confirmatorio (AFC) indicaron índices de ajuste aceptables (c2 = 176.7; c2 /gl = 2.18; p < .01; TLI = .93, IFI = .95, CFI = .95 y RMSEA = .05) así como pesos de regresión aceptables para la estructura trifactorial del cuestionario original. Para el segundo estudio se utilizó una muestra de 1009 deportistas mexicanos entre 12 y 39 años de edad (M = 17.28, DT = 2.98). Los resultados del AFC encontraron suficiente evidencia para la validez de constructo (c2 = 419.5; c2 /gl = 5.59; p < .01; TLI = .94, IFI = .96, CFI = .96 y RMSEA = .07). Los resultados en el análisis de correlación entre el Athlete Burnout Questionnaire (ABQ) y el Athlete Engagement Questionnaire (AEQ) pueden considerarse como prueba favorable de la validez discriminante. En cuanto a la fiabilidad, se encontraron resultados aceptables en consistencia interna en ambas fases del estudio, concluyendo que el ABQ es una herramienta útil para evaluar el burnout en depotistas mexicanos. The Athlete Burnout Questionnaire (ABQ) has become one of the most used tools to assess burnout in sport contexts. Despite a significant increase in research in this field, the literature has shown that there are no papers which provide psychometric data of the ABQ using a Mexican sample. Hence the objective of the present study was to analyze the psychometric properties of the Athlete Burnout Questionnaire of Mexican athletes. Data analysis was obtained using two studies. The first study consisted of 464 young athletes between 13 and 18 years old (M = 14.85, DT = 1.45). The results of the Confirmatory Factor Analysis (CFA) showed acceptable fit indices (c2 = 176.7; c2 /gl = 2.18; p < .01; TLI = .93, IFI = .95, CFI = .95 y RMSEA = .05) Acceptable results of load regression were also found for the original three factor questionnaire. A sample of 1009 Mexican athletes between 12 and 39 years of age (M = 17.28, SD = 2.98) were used for the second study. The results of the CFA found sufficient evidence for the construct validity (c2 = 419.5; 2cc2 /gl = 5.59; p < .01; TLI = .94, IFIS = .96, CFI = .96 and RMSEA = .07). The results in the analysis of correlation between the Athlete Burnout Questionnaire (ABQ) and the Athlete Engagement questionnaire (AEQ) can be considered as evidence of the discriminant validity. In regard to reliability, acceptable results were observed in internal consistency in both phases of the study, concluding that the ABQ is a useful tool to evaluate the burnout in Mexican athletes.

Introduction: recent research shows that people with high levels of self-efficacy for a healthy diet can control their weight. The Dieting Self-Efficacy Scale (DIET-SE) scale is a complete instrument that measures self-efficacy for a healthy diet, however, there are no Spanish versions for the Mexican population. Objective: the purpose of this study is to analyze the psychometric properties of the Mexican version of DIET-SE. Method: the sample consisted of 807 Mexican university students, of both sexes and aged between 17 and 48 years (M = 20.65, SD = 3.16). The parallel back-translation methodology was used to translate the DIET-SE scale into Spanish. In addition to the descriptive analysis and the Pearson correlation, the Cronbach alpha coefficient was used to measure the internal consistency and other indices were used for the factorial model. Results: the results of the CFA using the maximum likelihood estimation found good evidence for the construct validity (chi(2) = 175.68; gl = 35 [77-42]; chi(2)/gl = 5.02, p < 0.01; TLI = 0.92, IFI = 0.96, CFI = 0.95 y RMSEA = 0.07). The factorial loads of the eleven items showed acceptable values. The results in the correlation analysis between the DIET-SE and psychological well-being indicators can be considered as a favorable proof of the discriminant validity. In terms of reliability, acceptable results were found in internal consistency. Conclusion: the DIET-SE is a valid and reliable scale to evaluate the self-efficacy to maintain a diet in Mexican university students.

Introducción: las investigaciones empíricas demuestran que la autoeficacia percibida es una variable importante en el mantenimiento y la reducción del peso. Existen instrumentos que evalúan la autoeficacia percibida y su relación con la obesidad, pero en México aún son insuficientes.Objetivo: el propósito de la presente investigación es analizar las propiedades psicométricas de la versión mexicana del inventario de autoeficacia para el control de peso (AP-CP) en estudiantes universitarios del área de la salud.Métodos: en el estudio participaron 872 estudiantes universitarios de la Escuela de Ciencias de la Salud con edades comprendidas entre 17 y 47 (20,07 ± 2,61) años. Para evaluar la pertinencia del análisis factorial se realizó la prueba de esfericidad de Bartlett. Para evaluar el ajuste de los puntajes en factores específicos se llevó a cabo el método de componentes principales con rotación Varimax.Resultados: el análisis del índice de consistencia interna (coeficiente alfa de Cronbach) muestra adecuadas propiedades psicométricas para los tres factores resultantes: 0,856 para el factor “estilo de alimentación y externalidad”, 0,85 para el factor “actividad física programada” y 0,671 para el factor “actividad física cotidiana”.Conclusión: los hallazgos de este estudio muestran que el AP-CP es un instrumento confiable y válido para medir el nivel de autoeficacia para el control de peso en estudiantes universitarios mexicanos del área de la salud.

Una de las principales consecuencias negativas de la actual pandemia por COVID-19, es el impacto sobre la ansiedad y el estrés. Entre los factores que se deben tomar en cuenta para evaluar la respuesta psicosocial de los deportistas ante el COVID-19, están los factores sociodemográficos, por lo que el objetivo del presente estudio fue analizar si la percepción de estrés depende del sexo y el nivel de rendimiento en deportistas mexicanos durante la pandemia por COVID-19. La muestra de este estudio estuvo conformada por 596 deportistas mexicanos, de ambos sexos (mujeres = 40.4%) y con edades comprendidas entre los 13 y 40 años (M = 22.3, DE = 6.87). Los deportistas contestaron la Perceived Stress Scale (PSS-10) y un cuestionario para indagar sobre aspectos sociodemográficos. Los resultados obtenidos a través de la comparación de grupos, indicaron que las mujeres presentaron niveles superiores de estrés percibido que los hombres. Por otro lado, los deportistas de nivel amateur reportaron niveles más altos que los deportistas profesionales. Los resultados del análisis de diferencia muestran que la percepción de estrés depende del sexo y nivel de rendimiento. Estos resultados podrían utilizarse para incrementar la eficacia de los protocolos aplicados para controlar el estrés durante la pandemia por COVID-19 en deportistas. One of the main consequences of the current COVID-19 pandemic is the impact on anxiety and stress levels. Among the factors that must be taken into account to evaluate the psychosocial impact of COVID-19 on athletes are sociodemographic factors, so the objective of this study was to analyze if the perception of stress depends on gender and performance level in Mexican athletes during the COVID-19 pandemic. The sample of this study was made up of 596 Mexican athletes, of both sexes (women = 40.4%) and aged between 13 and 40 years (M = 22.3, SD = 6.87). The athletes answered the Perceived Stress Scale (PSS-10) and a questionnaire covering socio-demographic data. The results obtained through the comparison of groups, indicated that women presented higher levels of perceived stress than men. On the other hand, amateur athletes reported higher levels of perceived stress than professional athletes. The results of the difference analysis shows that the perception of stress depends on sex and performance level were predictors of perceived stress.

El estudio científico del apoyo social en México se ha visto limitado en su desarrollo, en parte debido a la falta de instrumentos específicos del contexto deportivo. Atendiendo a estas demandas de medición, el objetivo de esta investigación fue analizar la evidencia de validez y fiabilidad del Perceived Available Support in Sport Questionnaire (PASS-Q) en deportistas mexicanos. Participaron 991 deportistas (hombres = 66.3%) entre 12 y 32 años de edad (M = 17.22, DT = 2.83). Mediante el Análisis factorial confirmatorio se obtuvo suficiente evidencia de la validez de constructo. Los índices de bondad de ajuste del modelo tetrafactorial del PASS-Q fueron aceptables (χ2 = 474.949; χ2/df = 5.39; df = 88; p < .01; CFI = 0.96; TLI = 0.94; IFI = 0.96; RMSEA = 0.07). Las cargas factoriales estandarizadas resultaron estadísticamente significativas, superando el valor mínimo recomendado (λ = 0.40). En cuanto a la validez discriminante y concurrente, se encontró respaldo empírico a las correlaciones del PASS-Q con el ABQ y la SPSS. La fiabilidad fue alta con coeficientes alfa de Cronbach entre 0.81 y 0.84. El modelo tetrafactorial demostró invarianza configural, métrica y escalar en relación al género. El PASS-Q muestra adecuadas evidencias de validez y fiabilidad, recomendando su uso con deportistas mexicanos. Palabras clave: apoyo social, validez de constructo, consistencia interna, deportes. The development of scientific research on social support in Mexico has been limited, partly due to the lack of specific instruments about the sports environment. In response to this measurement necessity, the present study aims to analyze the evidence of validity and reliability of the Perceived Available Support in Sport Questionnaire (PASS-Q) in Mexican athletes. The sample was composed of 991 athletes, with ages between 12 and 32 years. Through Confirmatory factor analysis, it was obtained enough evidence for construct validity. The adjustment indexes used to evaluate the PASS-Q four-factor model seem to fit well (χ2 = 474.949; fg = 88; p < .01; CFI = 0.96; TLI = 0.94; IFI = 0.96; RMSEA = 0.07). The standardized factor loadings were statistically significant, exceeding the minimum recommended value (λ = 0.40). Regarding discriminant and concurrent validity, empirical support was found for the correlations of the PASS-Q with the ABQ and the SPSS. The reliability was high with Cronbach's alpha coefficient ​​between 0.81 and 0.84. The tetrafactorial model demonstrated configural, metric and scalar invariance in relation to gender. The PASS-Q shows adequate psychometric properties and its use with Mexican athletes is recommended. Keywords: Social support, construct validity, internal consistency, sports.
