Evidencias de validez y confiabilidad del Inventario de Trastornos de Ansiedad Generalizada en universitarios mexicanos / Evidence of validity and reliability of the Generalized Anxiety Disor-ders Inventory in Mexican university students

El presente estudio analiza las propiedades psicométricas, en hombres y mujeres universitarios, de la versión española propuesta por Blanco et al. (2017) para el Inventario de Trastornos de Ansiedad Generalizada. La mues¬tra total fue de 1220 participantes; 640 mujeres y 580 hombres, con una edad media de 20.40 años (DE= 1.92) y 20.54 años (DE= 2.04) respectivamente. Los análisis factoriales confirmatorios mostraron que una estructura trifactorial (síntomas cognitivos, trastornos del sueño y síntomas somáticos) es viable y adecuada para ambas poblaciones (mujeres y hombres) de acuerdo a los requisitos psicométricos establecidos. Además, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes en las dos poblaciones; sin embargo, existen diferencias entre las poblaciones para las medias de los factores síntomas cognitivos y síntomas somá¬ticos.

The present study analyses the psychometric properties, in university men and women, proposed for Blanco et al. (2017) to the Spanish version of the Generalized Anxiety Disorder Inventory. The overall sample consisted of 1220 subjects: 640 women and 580 men, with a mean age of 20.40 years (SD= 1.92) and 20.54 years (SD= 2.04) respectively. Psychometric analysis showed that a tri-factorial structure (cognitive symptoms, sleep disorders and somatic symptoms) was viable and adequate for both populations (men and woman) according to the established psychometric requirements. The results showed that factor structure, factor loadings and intercepts of the instrument could be considered invariant across groups; however, there are differences between groups for the means of factors cognitive anxiety and somatic symptoms.

Composition and Factorial Invariance for the Assessment of Body Image Dissatisfaction Questionnaire in Mexican Adolescents.

Body image is a mental representation that a person has, which could become a body dissatisfaction due to the pressure exerted by the culture, affecting several life stages specially in adolescents. The aim of this study was to analyze the psychometric properties and factorial invariance of the questionnaire to assess body image dissatisfaction. The sample consisted of 552 Mexican teenagers, 259 female, and 293 male, with a mean age of 12.91 ± 0.96 years. Confirmatory Factor Analyses show that a five-factor structure is viable and adequate. The five-factor structure (perceptual, emotional distress, behavioral, proposal to change, and fear of gaining weight) show adequate fit indices and validity, even though the obtained model does not completely correspond to that proposed by the authors of the scale, it continues to endorse the multifactorial component of body dissatisfaction. On the other hand, the factorial structure, the factor loadings, and the intercepts are considered invariant in both populations; however, there are differences between the populations for the means of the perceptual, emotional distress, and fear of gaining weight factors. This study serves as a premise for future research on the study of instruments for measuring body image in populations with different personal and cultural factors.

Mexican physical education teacher's self-reported and self-perception of teaching style / Auto-percepción y auto-reporte de estilos de enseñanza en profesores de educación física mexicanos / Autorrelato e autopercepção do estilo de ensino do professor mexicano de educação física

ABSTRACT To understand the self-reported and perception of teaching style used among Mexican physical education teachers. Participants included 104 (n=41 females and 63 males) elementary physical education teachers from northern Mexico. Results showed that a traditional teaching style tends to be mainly used either by male and female's physical education teachers. Showing differences between genders and teaching styles. Female teachers tend to combine a traditional teaching style with one that connects with students engaging in physical activity, developing positive values and attitudes. Cultural context plays an important aspect when developing a teaching self-perception.

Índice de asimetría bilateral morfológica de extremidades inferiores y superiores en jugadores de baloncesto universitario / The upper and lower limb bilateral morphological asymmetry index in university basketball players

Introducción: El baloncesto es objeto de múltiples estudios que incluye la valoración mediante tecnologías actuales como la bioimpedancia. Objetivo: Comparar los índices de asimetría (IA) de las extremidades superiores e inferiores en jugadores de baloncesto universitario por nivel deportivo. Método: Se evaluaron 24 jugadores de baloncesto de diferente nivel competitivo, representativo 1) universitario (n = 12) y 2) facultad (n = 12). Se determinó la circunferencia de brazos y piernas, además de masa magra y grasa por bioimpedancia. Se determinó el índice de asimetría de los miembros inferiores y superiores y se compararon por nivel deportivo. Resultados: La comparación de los índices de asimetría entre brazos y piernas en el grupo total identificó diferencias estadísticamente significativas (p < 0,05) en lo referente a la masa grasa, con mayor adiposidad en extremidades superiores, y un índice de asimetría de -10,8. Cuando se compararon las mismas variables en función del nivel deportivo, los jugadores representantes de la universidad mostraron mayores valores (p < 0,05) en el índice de asimetría de la masa total, circunferencias, masa magra y masa grasa. Las comparaciones intergrupales señalan diferencias en los índices de asimetría del brazo vs. la pierna en masa magra para ambos grupos (p < 0,05) mientras que los de la facultad mostraron diferencia también para grasa con índice de asimetría de 18,3 (p < 0,05). Conclusiones: Indistintamente del nivel deportivo, existen diferentes niveles del índice de asimetría entre extremidades superiores e inferiores en el componente de masa grasa, aunque menores valores del índice de asimetría fueron característicos de los individuos de mayor nivel deportivo(AU)

Introduction: Basketball has been the object of many studies, including assessments based on current technologies such as bioimpedance. Objective: Compare the asymmetry indices (AI) for upper and lower limbs in university basketball players. Methods: An evaluation was conducted of 24 basketball players from different competitive levels, representing 1) the university (n = 12) and 2) the school (n = 12). Determination was made of arm and leg circumference, as well as lean mass and fat by bioimpedance. The lower and upper limb asymmetry index was estimated and compared between the competitive levels. Results: Comparison of the arms and legs asymmetry indices in the total group revealed statistically significant differences (p < 0.05) as to fat mass, with greater adiposity in the upper limbs and an asymmetry index of 10.8. Comparison of the same variables between the sports levels found that players representing the university displayed higher values (p < 0.05) in the asymmetry index for total mass, circumferences, lean mass and fat mass. Comparison between the groups found differences in the arm vs. leg asymmetry indices for lean mass in both groups (p < 0.05), whereas the school players also showed differences for fat, with an asymmetry index of 18.3 (p < 0.05). Conclusions: Regardless of the sports level, different asymmetry indices are found between upper and lower limbs as to fat mass, though smaller asymmetry index values were characteristic of individuals from a higher sports level(AU)

How is my teaching? teaching styles among Mexican physical education teachers / Bomo está meu ensino?: estilos de ensino entre professores de educação física mexicanos / ¿Como es mi enseñanza?: estilos de enseñanza entre docentes mexicanos de educación física

Abstract Purpose: To compare teaching styles (TS) and years of experience among Mexican Physical Education (PE) teachers. Method: 129 PE teachers from the City of Chihuahua completed the Teaching Styles in Physical Education questionnaire; average age: 42.3 (±9.6) years; average time teaching PE: 15.7 (±7.9) years. Subjects were divided in 6 groups according to years of experience: -6, 6-11, 12-17, 18-23, 24-29 and 30+. Results: no differences were found in traditional TS among groups, but all PE teachers showed high tendency to use that TS. The 30+ group showed values higher than 6-11 (p<0.05). Conclusion: There is a tendency to implement a traditional teaching style, although years of experience allow PE teachers to use teaching styles that fit students' needs and their interest to participate in Physical Education classes.

Resumo Objetivo: comparar estilos de ensino (EE) e anos de experiência entre professores de Educação Física (EF) mexicanos. Método: 129 professores de EF da cidade de Chihuahua, média de idade: 42,3 anos (± 9,6) anos; experiência como professor de EF: 15,7 (± 7,9) anos; completaram o Questionário sobre EE em EF. Os sujeitos foram divididos em seis grupos de acordo com os anos de experiência: - 6, 6-11, 12-17, 18-23, 24-29 e 30+. Resultados: não foram encontradas diferenças em EE tradicional por grupo, mas todos os professores de EF mostraram tendência elevada a usar esse EE. O grupo 30+ apresentou valores superiores ao grupo 6-11 entre estilo cognitivo e escala criativa (p <0,05). Conclusão: há uma tendência a implementar o EE tradicional, embora os anos de experiência permitam aos professores de EF usar um EE ajustado às necessidades e interesses dos alunos em participar do curso de EF.
