Widely used dichotomous categorical measures of pregnancy intentions do not represent well the complexity of factors involved in women's intentions. We used a variety of exploratory statistical methods to examine measures of pregnancy intention in the 2002 National Survey of Family Growth (N = 3,032 pregnancies). Factor analyses identified two key dimensions of pregnancy intentions (desire and mistiming) and two smaller nondimensional categories (overdue and don't care). Desire included both affective and cognitive variables, as well as partner-specific factors. Similar pregnancy-intention dimensions were found for adolescent and adult women, across socioeconomic status, and among racial and ethnic groups. Both desire and mistiming were highly predictive of the decision to abort or continue the pregnancy. These analyses strongly support prior demographic thinking about the importance of both the timing of pregnancy and wanting a baby, but suggest that multidimensional rather than simple categorical measures of pregnancy intentions should be used.
广泛使用的关于怀孕意愿的二分法分类测量并不能很好地体现女性怀孕意愿中所涉及因素的复杂性。我们运用了多种探索性统计方法，对2002年全国家庭成长调查中的怀孕意愿测量进行了检验（N = 3032次怀孕）。因子分析确定了怀孕意愿的两个关键维度（意愿和时机不当）以及两个较小的无维度类别（过期和不在乎）。意愿包括情感和认知变量，以及特定伴侣因素。在青少年和成年女性中，在不同社会经济地位以及不同种族和族裔群体中，都发现了类似的怀孕意愿维度。意愿和时机不当都对堕胎或继续妊娠的决定具有高度预测性。这些分析有力地支持了之前关于怀孕时机和想要孩子的重要性的人口统计学观点，但表明应该使用怀孕意愿的多维而非简单分类测量方法。
