To develop and test a comprehensive tool for measuring women's attitudes toward the possibility of becoming pregnant.
Cross-sectional mixed methods study.
Two obstetric/gynecologic (OB/GYN) clinics and one family planning clinic in Baltimore, Maryland.
One-hundred thirty (130) nonpregnant, primarily African American women (84%) age 18 to 29.
Participants completed a computer-based survey as part of a larger retrospective mixed-methods study. The Attitude Toward Potential Pregnancy Scale (APPS) was assessed using exploratory factor analysis and hypothesis testing.
Cronbach's alpha for internal consistency for the APPS was 0.86. Item-total correlations ranged from 0.56 to 0.75. All items loaded on one factor. Support for construct validity was demonstrated using logistic regression, where the odds of being a highly effective contraceptive user decreased by 8% with each one-point increase in score on the APPS (odds ratio = 0.92; confidence interval [0.87, 0.98]).
This study provides support for reliability and validity of the APPS. The APPS may be a useful tool for understanding pregnancy attitude in future studies and in clinical practice. Further research is needed to assess the usefulness of the scale with other groups of women, its utility in the clinical practice setting, and its potential predictive validity for unintended pregnancy.
开发并测试一种用于衡量女性对怀孕可能性态度的综合工具。
横断面混合方法研究。
马里兰州巴尔的摩的两家妇产科（OB/GYN）诊所和一家计划生育诊所。
130名未怀孕的主要为非裔美国女性（84%），年龄在18至29岁之间。
作为一项更大规模回顾性混合方法研究的一部分，参与者完成了一项基于计算机的调查。使用探索性因素分析和假设检验对潜在怀孕态度量表（APPS）进行评估。
APPS内部一致性的Cronbach's alpha为0.86。项目与总分的相关性范围为0.56至0.75。所有项目均加载在一个因素上。使用逻辑回归证明了对结构效度的支持，APPS得分每增加一分，高效使用避孕药具的几率降低8%（优势比=0.92；置信区间[0.87, 0.98]）。
本研究为APPS的信度和效度提供了支持。在未来研究和临床实践中，APPS可能是一种用于理解怀孕态度的有用工具。需要进一步研究以评估该量表在其他女性群体中的有用性、其在临床实践环境中的效用以及其对意外怀孕的潜在预测效度。
