Cancer is the leading cause of death among Asian American women, and the death rate has increased almost 200% since 1990. Previous research has applied the transtheoretical model constructs to examine cancer screening behavior; however, to our knowledge, this is the first such investigation to examine relationships between stages of mammography adoption and decision balance among Asian American women. This article presents study findings from a convenience sample of 228 women aged 40 to 81 years (mean = 55.0, SD = 9.6) residing in southeastern Michigan. The current study demonstrates excellent support for the psychometric properties of a pros and cons measure, with promising Cronbach alphas above .70. Results from confirmatory factor analysis also support the factor structure derived from exploratory factor analysis with good model fit indices. This study also provides some support on transtheoretical model-hypothesized relationships in this sample of Asian American women that, as the stages of adoption of mammography proceeded from earlier to later ones, the decisional balance would become more favorable. The specific beliefs (both positive and negative) associated with the various stages of mammography adoption have implications for health professionals in developing stage-matched interventions to motivate women in adopting regular mammography.
癌症是亚裔美国女性的主要死因,自1990年以来死亡率几乎增长了200%。以往的研究应用了跨理论模型结构来检验癌症筛查行为;然而,据我们所知,这是首次此类调查,旨在研究亚裔美国女性乳房X光检查采用阶段与决策平衡之间的关系。本文介绍了对居住在密歇根州东南部的228名年龄在40至81岁(平均年龄 = 55.0,标准差 = 9.6)的女性进行便利抽样的研究结果。当前研究对利弊衡量的心理测量特性提供了有力支持,Cronbach阿尔法系数高于0.70,前景良好。验证性因素分析的结果也支持了探索性因素分析得出的因素结构,模型拟合指数良好。本研究还为该亚裔美国女性样本中的跨理论模型假设关系提供了一些支持,即随着乳房X光检查采用阶段从早期向后期推进,决策平衡会变得更加有利。与乳房X光检查采用的各个阶段相关的具体信念(包括积极和消极的),对于健康专业人员制定与阶段相匹配的干预措施以激励女性定期进行乳房X光检查具有启示意义。
