Level of physical activity as a key determinant of healthy lifestyle less than is required in individuals particularly women. Applying theories of behavioral change about complex behaviors such as physical activity leads to identify effective factors and their relations. The aim of this study was to determine predictors of physical activity behavior based on the Theory of Planned Behavior in military staff's wives in Tehran. This cross-sectional study was performed in 180 military personnel's spouses residing in organizational houses, in Tehran, Iran in 2014. The participants were randomly selected with multi-stage cluster sampling. The validity and reliability of the theory based scale evaluated before conducting the path analysis. Statistical analysis was carried out using SPSS16 and LISREL8.8. The results indicated the model explained 77% and 17% of intention and behavior variance. Subjective norms (Beta=0.83) and intention (Beta=0.37) were the strongest predictors of intention and behavior, respectively. The instrumental and affective attitude had no significant path to intention and behavior. The direct relation of perceived behavioral control to behavior was non-significant. This research demonstrated relative importance and relationships of Theory of Planned Behavior constructs in physical activity behavior of military personnel's spouses in Tehran. It is essential to consider these determinants in designing of educational interventions for promoting and maintaining physical activity behavior in this target group.
身体活动水平是健康生活方式的关键决定因素，但在个体尤其是女性中，其水平低于所需程度。应用关于诸如身体活动等复杂行为的行为改变理论，有助于识别有效因素及其关系。本研究的目的是基于计划行为理论确定德黑兰军事人员妻子身体活动行为的预测因素。这项横断面研究于2014年在伊朗德黑兰居住在单位住房的180名军事人员配偶中进行。参与者通过多阶段整群抽样随机选取。在进行路径分析之前，对基于该理论的量表的效度和信度进行了评估。使用SPSS16和LISREL8.8进行统计分析。结果表明，该模型分别解释了77%和17%的意向和行为方差。主观规范（β=0.83）和意向（β=0.37）分别是意向和行为的最强预测因素。工具性态度和情感性态度与意向和行为没有显著路径。感知行为控制与行为的直接关系不显著。本研究证明了计划行为理论结构在德黑兰军事人员配偶身体活动行为中的相对重要性和关系。在为该目标群体设计促进和维持身体活动行为的教育干预措施时，必须考虑这些决定因素。
