This article describes the association of external and psychosocial factors with the stages of change for moderate-intensity physical activity among individuals with generally low socioeconomic positions.
A self-administered questionnaire among individuals aged 18-65 years (response rate 60%, n = 2781) in deprived neighborhoods in Eindhoven, The Netherlands, was conducted in September 2000. To identify factors associated with stages of change an ordinal logistic regression model, the "Threshold of Change model (TCM)", was used to analyze the data.
Thirty-six percent of the respondents were in the pre-action stages, 15% was in action and 49% in maintenance. Individuals who were, older, lower educated, had low health locus of control, had less knowledge of physical activity issues, and presented other risky health behaviors, were more likely to be in a lower stage of change category. A positive attitude, high self-efficacy expectations, perceiving the physical activity level of others as high, and much social support were associated with the higher stages of change categories.
The distribution across the stages of change supports the need to improve physical activity behavior in these deprived neighborhoods. Interventions need to be tailored to the psychosocial, and the external factors that are likely to play a role in the behavioral change process.
本文描述了社会经济地位普遍较低的个体中，外部因素和心理社会因素与中等强度体育活动改变阶段之间的关联。
2000年9月，在荷兰埃因霍温贫困社区对18 - 65岁的个体进行了一项自填式问卷调查（回复率60%，n = 2781）。为了确定与改变阶段相关的因素，使用了序数逻辑回归模型“改变阈值模型（TCM）”来分析数据。
36%的受访者处于行动前阶段，15%处于行动阶段，49%处于维持阶段。年龄较大、受教育程度较低、健康控制点较低、对体育活动问题了解较少以及存在其他危险健康行为的个体，更有可能处于较低的改变阶段类别。积极的态度、较高的自我效能期望、认为他人的体育活动水平较高以及获得较多社会支持与较高的改变阶段类别相关。
改变阶段的分布情况表明，有必要改善这些贫困社区的体育活动行为。干预措施需要针对心理社会因素以及可能在行为改变过程中发挥作用的外部因素进行调整。
