Adolescents especially middle school girls do not follow 60 min of regular physical activity (RPA), recommended by WHO, and endure physical activity decline. Using theory-based interventional program, considering the age of decline in RPA, seems to be effective. The aim of this study was to determine the effects of educational program, based on PRECEDE and Trans-Theoretical models, on preventing decline in RPA and improving it among 7th grade girl students.
Randomized controlled trial.
This study was conducted on 7th grade girl students in Hamadan, west of Iran from 2015-16. Participants were divided into intervention (N=179) and control (N=165) groups by random assignment. Physical activity questionnaire for adolescents and the model-based questionnaire were used before and after intervention. Intervention included two months education and six months follow up. The effects of intervention were determined by statistical test and analysis of covariance using SPSS version 16.
The higher change in the mean scores was observed in self-efficacy (0.86), counter condition (0.66) and helping relationship (0.57) in the intervention group (P≤0.001). In addition, a significant difference (P ≤0.001) was observed between the two groups 6 months after the intervention in all constructs of model. The mean score of doing physical activity in the intervention group increased from 2.50 to 3.17 that it was differed significantly from the control group (P≤0.001). CONCLUSIONS: School based intervention using PRECEDE and Trans-Theoretical models might prevent girl students' RPA decline and improve their RPA.
青少年尤其是初中女生未遵循世界卫生组织建议的60分钟常规体育活动（RPA），且体育活动量持续下降。采用基于理论的干预方案，考虑到RPA下降的年龄阶段，似乎会有效果。本研究的目的是确定基于“教育诊断与评价程序”（PRECEDE）和跨理论模型的教育方案对预防七年级女生RPA下降及改善其RPA的效果。
随机对照试验。
本研究于2015 - 2016年在伊朗西部哈马丹的七年级女生中开展。参与者通过随机分配分为干预组（N = 179）和对照组（N = 165）。在干预前后使用青少年体育活动问卷和基于模型的问卷。干预包括两个月的教育和六个月的随访。使用SPSS 16版通过统计检验和协方差分析确定干预效果。
干预组在自我效能感（0.86）、对抗条件（0.66）和帮助关系（0.57）方面的平均得分变化更高（P≤0.001）。此外，干预6个月后，两组在模型的所有构成要素上均观察到显著差异（P≤0.001）。干预组的体育活动平均得分从2.50提高到3.17，与对照组有显著差异（P≤0.001）。
采用PRECEDE和跨理论模型的校本干预可能预防女生的RPA下降并改善其RPA。
