Asian immigrant and Asian American women are less likely to use oral contraceptives (OCs) and tend to rely on low-efficacy methods of contraception. This contraceptive pattern remains poorly understood, in part, because no theory-driven measurement exists to assess psychosocial determinants essential in explaining behaviors related to OC use in this population. The current study aimed to evaluate the psychometric properties of a measure of attitudes and subjective norms toward OC use among Korean American women as a first step to determine whether the measure can be used in this population and, potentially, in other Asian ethnic groups.
The sample consisted of 329 Korean immigrant women living in New York City. The theory of reasoned action guided the development of the measure assessing attitudes and norms. Psychometric evaluation included item analysis, internal consistency estimates of reliability, and construct validity (i.e., factorial, discriminant, and predictive).
All item-total correlations were above the recommendation of .30. The Cronbach's alpha for the attitudes and subjective norms measure was .88 and .86, respectively. Exploratory factor analyses revealed four interpretable factors, and confirmatory factor analyses confirmed that the factor structures derived from the exploratory factor analyses fit the data well. Discriminant and predictive validity of the measure were also established.
The study provides support for the validity and reliability of the measure and its use for determining the degree to which Korean immigrant women intend to use OCs.
亚洲移民女性和亚裔美国女性使用口服避孕药(OCs)的可能性较低,且倾向于依赖低效的避孕方法。这种避孕模式仍未得到充分理解,部分原因是不存在理论驱动的测量方法来评估在解释该人群与口服避孕药使用相关行为中至关重要的心理社会决定因素。本研究旨在评估一项针对韩裔美国女性对口服避孕药使用的态度和主观规范测量工具的心理测量特性,作为确定该测量工具是否可用于该人群以及可能用于其他亚洲族裔群体的第一步。
样本包括329名居住在纽约市的韩裔移民女性。理性行动理论指导了评估态度和规范的测量工具的开发。心理测量评估包括项目分析、可靠性的内部一致性估计以及结构效度(即因子、判别和预测效度)。
所有项目与总分的相关性均高于0.30的推荐值。态度和主观规范测量工具的克朗巴哈系数分别为0.88和0.86。探索性因子分析揭示了四个可解释的因子,验证性因子分析证实了从探索性因子分析得出的因子结构与数据拟合良好。该测量工具的判别效度和预测效度也得到了确立。
该研究为测量工具的有效性和可靠性及其用于确定韩裔移民女性使用口服避孕药的意愿程度提供了支持。
