We examined both direct and indirect effects of the Healthy Body Image (HBI) intervention on positive embodiment among Norwegian high school students. In total, 2446 12th grade boys (43 %) and girls (mean age 16.8 years) from 30 schools participated in a cluster-randomized controlled study with the HBI intervention and a control condition as the study arms. We tested mediation models using path analysis and found that among several hypothesized mediators, only self-esteem mediated a positive intervention effect on positive embodiment for both boys and girls. A direct effect of the intervention on positive embodiment was only found in girls. The study provides novel findings indicating that health promotion interventions to address a positive embodiment should focus on enhancing adolescent's self-esteem. Serial mediation modeling might reveal more complex explanations of change mechanisms and could further evolve current knowledge.
我们考察了“健康身体意象”（HBI）干预对挪威高中生积极身体认知的直接和间接影响。共有来自 30 所学校的 2446 名 12 年级男生（43%）和女生（平均年龄 16.8 岁）参与了一项以 HBI 干预和对照条件为研究组的群组随机对照研究。我们使用路径分析检验了中介模型，发现在所假设的几个中介因素中，只有自尊对男孩和女孩的积极身体认知的积极干预效果起中介作用。仅在女生中发现了干预对积极身体认知的直接影响。本研究提供了新的发现，表明为解决积极身体认知而进行的健康促进干预应侧重于增强青少年的自尊。序列中介模型可能揭示出变化机制更复杂的解释，并进一步丰富当前的知识。
