背景：了解影响孕前计划决策的因素对降低所有糖尿病妇女的意外怀孕率和妊娠相关并发症具有重要意义。在此之前，没有关于青春期糖尿病女性生殖健康相关信念、态度或行为的研究。健康信念模型（HBM）、理性行为理论和社会认知理论等社会认知模型是影响这些行为结果的因素。目的：比较这三种理论对青少年糖尿病患者生殖健康行为的预测能力，并确定三种理论中最强预测因子的复合模型。方法：采用同性研究助理电话访谈的方式，采用生殖健康态度与行为（RHAB）问卷对来自4个医疗中心的87名1型糖尿病（T1D）女性青少年患者进行调查。测量代表人口变量、三种理论的结构和行为结果。采用标准多元回归分析检验三种理论在结局变量[使用节育的意向（BC）]中的预测。结果：在考虑的三个理论中，HBM解释了使用BC意愿的最高方差百分比（24.4%）。最好的复合模型包括感知障碍、行动提示和自我效能（解释26.1%的方差）。这三个变量也是考虑的所有构念中最强的预测因子。结论：在这个患有T1D的青春期女性样本中，三种理论中最强的预测因子似乎是感知障碍、行动线索和自我效能感。减少高危人群未来意外怀孕的干预研究可以集中在针对这些可改变因素的策略上。
Background: Understanding factors that affect decision-making in using preconception planning is important to reduce the rate of unplanned pregnancies and pregnancy-related complications in all women with diabetes. Previously, there were no studies of reproductive health-related beliefs, attitudes, or behaviors of adolescent women with diabetes. Constructs from social cognitive models, such as, the health belief model (HBM), theory of reasoned action, and social cognitive theory, are factors that can influence these behavioral outcomes.Objective: To compare the predictive powers of these three theories in regard to decision-making with reproductive health behaviors in teens with diabetes and to identify a composite model of the strongest predictors across all three theories.Method: Data were collected from a telephone interview by same-gender research assistants on a sample of 87 female adolescents with type 1 diabetes (T1D) from four medical centers using the reproductive health attitudes and behavior (RHAB) questionnaire. Measures represent demographic variables, constructs of the three theories, and behavioral outcomes. Standard multiple regression analyses were used to examine the prediction of the three theories in the outcome variable [intention for using birth control (BC)].Results: Among the three theories considered, the HBM explained the highest percent of variance (24.4%) in intention to using BC. The best composite model consisted of perceived barriers, cues to action, and self-efficacy (explaining 26.1% of the variance). These three variables were also the strongest predictors among all constructs considered.Conclusion: In this sample of adolescent females with T1D, the strongest predictors from the three theories for intention to using BC appeared to be perceived barriers, cues to action, and self-efficacy. Intervention studies to decrease future unplanned pregnancies in this high-risk population could focus on strategies to target these factors that are amenable to change.
