ABSTRACT

Se diseña un modelo que explora las relaciones entre las dimensiones del autoconcepto y algunas conductas beneficiosas (consumo de alimentos sanos y práctica de deporte) y de riesgo para la salud (consumo de tabaco, alcohol y cannabis, y de alimentos insanos) en ambos sexos. Contamos con una muestra representativa de 1.038 adolescentes de la Comunidad Valenciana de entre 15 y 18 años (528 chicas y 510 chicos, M edad= 16.3; DT= .92). Se empleó el «path análisis» con el método de máxima verosimilitud del programa Lisrel VIII. Los resultados muestran un buen ajuste del modelo a los datos tanto para los chicos (χ2/gl= 2.57; RMSR= .04; RMSEA= 0.5; GFI= .98; NNFI= .91; CFI= .97; CN= 350.10) como para las chicas (χ2/gl= 3.28; RMSR= .04; RMSEA= 0.6; GFI= .98; NNFI= .87; CFI= .95; CN= 284.42). En ambos sexos, la adecuación conductual, la aceptación social y la amistad íntima son los mejores predictores de las conductas de riesgo para la salud. La competencia deportiva ejerce una influencia indirecta sobre las conductas de salud, actuando la participación deportiva como variable mediadora en esta relación


A gender-based model has been designed to study the relationships that exist among self-concept dimensions and some health-promoting behaviours (consumption of healthy food and participation in sports) and health-risk behaviours (consumption of tobacco, alcohol, cannabis and unhealthy food). The model was employed on a representative sample of 1,038 adolescents from the Valencian Community, aged between 15 and 18 years old (528 girls and 510 boys, M age= 16.3; SD= .92). Path analysis with the Lisrel VIII program maximum likelihood method was used. The results show the model’s good fit to the data with regard to both the boys (χ2/gl= 2.57; RMSR= .04; RMSEA= 0.5; GFI= .98; NNFI= .91; CFI= .97; CN= 350.10) and the girls (χ2/gl= 3.28; RMSR= .04; RMSEA= 0.6; GFI= .98; NNFI= .87; CFI= .95; CN= 284.42). For the two sexes, behavioural conduct, social acceptance and close friendship emerged as good predictors of health-risk behaviours. Athletic competence had an indirect influence on health behaviours, with participation in sports being a mediating variable in that relationship
