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 (chi 2 /gl= 2.57; RMSR= .04; RMSEA= 0.5; GFI= .98; NNFI= .91; CFI= .97; CN= 350.10) and the girls (chi 2 /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.
已设计出一种基于性别的模型，用于研究自我概念维度与一些健康促进行为（健康食品消费和参与体育运动）以及健康风险行为（烟草、酒精、大麻和不健康食品消费）之间存在的关系。该模型应用于来自巴伦西亚自治区的1038名15至18岁青少年的代表性样本（528名女孩和510名男孩，平均年龄 = 16.3；标准差 = 0.92）。使用Lisrel VIII程序最大似然法进行路径分析。结果表明，该模型对男孩（卡方/自由度 = 2.57；均方根残差 = 0.04；近似误差均方根 = 0.5；拟合优度指数 = 0.98；非规范拟合指数 = 0.91；比较拟合指数 = 0.97；准则值 = 350.10）和女孩（卡方/自由度 = 3.28；均方根残差 = 0.04；近似误差均方根 = 0.6；拟合优度指数 = 0.98；非规范拟合指数 = 0.87；比较拟合指数 = 0.95；准则值 = 284.42）的数据拟合良好。对于两性而言，行为举止、社会接纳和亲密友谊是健康风险行为的良好预测指标。运动能力对健康行为有间接影响，参与体育运动是该关系中的一个中介变量。
