Background and aim Expenditure on adolescents' health promotion is critical to enhancing quality of life and fundamental for the prosperity of countries. This study tried to investigate the relationships between information-motivation-behavioral skills (IMB) model constructs as predictors of high school student's health-promoting lifestyle (HPL) in Southwest Iran. Methods This cross-sectional descriptive-analytic study was conducted on 400 students in Southwest Iran. Sample size required for this study was obtained using Soper's structural equation modeling (SEM) calculator. The stratified random sampling method was used in this study. A path analysis was taken to evaluate the HPL main determinants utilizing SEM. Results Information only had a significant indirect relationship with adolescents' HPL. But, both motivation and behavioral skills constructs had significant direct and indirect relationship with adolescents' HPL. The behavioral skill construct was the most imperative predictor variable. In general, behavioral skills construct (75%), motivation (66%) and knowledge (50%) constructs had the highest impact on HPL. The IMB model was able to explain 71% of the variance in adolescents' HPL. Conclusion The findings of the study showed that the IMB model was appropriate for explaining adolescents' HPL. It is necessary that actions are taken to improve behavioral skills and promote adolescents' HPL.
背景与目的 青少年健康促进支出对于提高生活质量至关重要，也是国家繁荣的基础。本研究旨在调查信息-动机-行为技能（IMB）模型构建因素与伊朗西南部高中生健康促进生活方式（HPL）预测指标之间的关系。方法 本横断面描述性分析研究对伊朗西南部的400名学生进行。本研究所需样本量使用索珀结构方程模型（SEM）计算器获得。本研究采用分层随机抽样方法。利用SEM进行路径分析以评估HPL的主要决定因素。结果 信息仅与青少年的HPL存在显著的间接关系。但是，动机和行为技能构建因素均与青少年的HPL存在显著的直接和间接关系。行为技能构建因素是最关键的预测变量。总体而言，行为技能构建因素（75%）、动机（66%）和知识（50%）构建因素对HPL的影响最大。IMB模型能够解释青少年HPL中71%的方差。结论 研究结果表明，IMB模型适用于解释青少年的HPL。有必要采取行动提高行为技能并促进青少年的HPL。
