RESUMO
Self-concept is one of the most relevant variables in the field of personality, and a negative self-perception can pose a risk to the adolescent's development. The present study aimed to analyze the psychometric properties proposed by Aguirre and collaborators for the dimensional self-concept questionnaire (AUDIM-M). The total sample was 560 adolescents from the city of Chihuahua, Chihuahua, with a mean age of 12.96 ± 0.88 years. The factor structure of the questionnaire was analyzed using confirmatory factor analysis. The analyses show that a four-factor structure is viable and adequate (GFI 0.964; RMSEA 0.057; CFI 0.950). The four-factor structure (personal self-concept, physical self-concept, social self-concept, and academic self-concept), according to statistical and substantive criteria, shows adequate indicators of reliability and validity adjustment. The model obtained coincides with that proposed by Aguirre et al. Improving adolescents' self-concept undoubtedly contributes to their quality of life, hence the need for valid and reliable instruments for its measurement; this study could be a first approach for future research.
RESUMO
Anxiety about aging is an important mediating factor in attitudes and behavior toward elderly individuals as well as a mediating factor in the adjustment to one's own aging processes. The aim of this study was to analyze the factor structure, internal consistency and factorial invariance by sex of the Lasher and Faulkender Anxiety about Aging Scale. The sample consisted of 601 Mexican older adults, 394 women and 207 men, with a mean age of 70.69 ± 8.10 years. The factor structure of the questionnaire was analyzed using confirmatory factor analysis. Analyses show that a four-factor structure is feasible and adequate. The four-factor structure (fear of the elderly, psychological concerns, physical appearance and fear of loss), according to statistical and substantive criteria, showed adequate reliability and validity indicators. However, the obtained model does not fully coincide with that proposed by the questionnaire authors, although it continues to support the multi-factor component of anxiety about aging. On the other hand, the factor structure, the factor loadings and the intercepts are considered invariant in the two populations (men and women); however, there are differences between populations on the means of the physical appearance and fear of loss factors.
RESUMO
The traditional teaching style in which the teacher is in control and there is a submissive attitude in students is predominant in Mexico. The development of identity in preadolescence is subjected to social groups, which could develop interpersonal difficulties through the controlling teaching style. Although the fear of negative evaluation in students and competitive sport has been studied in education, relatively little research has been done in the area of physical education in relation to the controlling style. The purpose of this study was to investigate the correlation and predictive relationship between controlling teaching and the fear of negative evaluation mediated by the frustration of the basic psychological needs (BPN), controlled motivation, and individualism/competitiveness through the theoretical framework of self-determination theory. Participants were 1132 students in the fifth and sixth grades in public elementary schools in the state of Chihuahua, Mexico, with ages between 10 and 13 (M = 10.51 years; SD = 0.66 years). Results indicate the perceived controlling teaching style positively predicted the fear of negative evaluation in students of this study through BPN frustration, that is positively related to low-quality motivation, which is related to a higher level of individualism/competitiveness. This, in turn, is proven to be a predictor of the fear of negative evaluation. The results also discuss the promotion of the autonomy support style, avoiding the controlling teaching style, for the minimization of negative results related to the perception of fear and the development of student well-being both within and beyond the school context.
RESUMO
El objetivo principal del presente estudio fue examinar el efecto de la práctica regular de actividad física y el autoconcepto físico sobre la percepción de bienestar psicológico en estudiantes universitarias mexicanas mediante un modelo de ecuaciones estructurales. Un total de 532 mujeres universitarias mexicanas de 18-26 años de edad cumplimentaron el Cuestionario Internacional de Actividad Física, el Cuestionario de Autoconcepto Físico Modificado y las Escalas de Bienestar Psicológico. Los resultados del modelo de ecuaciones estructurales mostraron que la práctica de actividad física, a través de la competencia motora-atractivo físico, tiene un efecto indirecto positivo sobre la percepción de bienestar psicológico en la dimensión de autoaceptación y ésta a su vez ejerce un efecto directo positivo sobre el crecimiento personal. El modelo propuesto obtiene un ajuste satisfactorio, explicando el 43% de la varianza en la percepción de bienestar psicológico en la dimensión de crecimiento personal (variable criterio) (AU)
The main purpose of the present study was to examine the effect of regular physical activity and physical self-concept on the perception of psychological well-being in women Mexican university students using structural equation modeling. A total of 532 women Mexican university students aged 18-26 years old completed the International Physical Activity Questionnaire, Modified Questionnaire of Physical Self-concept and Psychological Well-Being Scales. The results of the structural equation modeling showed that the practice of physical activity, through motor competency-physical attractiveness, has an indirect positive effect on the perception of psychological well-being in the dimension of self-acceptance and this in turn has a direct positive effect on personal growth. The proposed model obtains a satisfactory fit, accounting for 43% of the variance in perception of psychological well-being in the dimension of personal growth (variable criteria) (AU)
