The objective was to describe the development and assess evidence of the validity of a patient-reported scale measuring the interpersonal quality of contraceptive counseling.
We performed initial item selection based on qualitative work regarding patient preferences for contraceptive counseling and a review of patient-reported measures of communication. We then administered these items as part of a cohort study of women receiving contraceptive counseling, along with items measuring patient satisfaction with counseling and method choice, and coded audio recordings of the contraceptive counseling visits for patient-centered communication. We determined the final scale based on interitem correlations and exploratory factor analysis. Predictive validity of the scale has been demonstrated previously. We assessed content, construct, convergent and discriminant validity by investigating associations between the final scale and the satisfaction and audio-recording-derived measures using mixed effects logistic regression.
The items were administered to 346 women between 2009 and 2012 in the San Francisco area. We selected an 11-item, 1-factor Interpersonal Quality of Family Planning (IQFP) scale, with a Cronbach's alpha of 0.95. This scale showed positive associations with measures of satisfaction with counseling and with the chosen method. IQFP was also associated with provider communication practices, including eliciting the patient perspective and demonstrating empathy.
The IQFP scale demonstrates construct, convergent, discriminant and predictive validity for measuring the interpersonal quality of contraceptive counseling. It shows promise as a measure that can be used in research and quality improvement efforts to ensure that patients' experiences and preferences are prioritized in family planning care.
描述一种用于衡量避孕咨询人际质量的患者报告量表的开发过程，并评估其有效性证据。
我们基于关于患者对避孕咨询偏好的定性研究以及对患者报告的沟通测量指标的回顾进行了初始项目选择。然后，我们将这些项目作为接受避孕咨询的女性队列研究的一部分进行施测，同时施测测量患者对咨询和方法选择满意度的项目，并对避孕咨询访视的录音进行编码以评估以患者为中心的沟通。我们根据项目间相关性和探索性因素分析确定了最终量表。该量表的预测效度此前已得到证实。我们通过使用混合效应逻辑回归研究最终量表与满意度及录音衍生测量指标之间的关联，评估了内容效度、结构效度、收敛效度和区分效度。
2009年至2012年期间，这些项目被施测于旧金山地区的346名女性。我们选择了一个包含11个项目的单因素计划生育人际质量（IQFP）量表，其克朗巴哈系数为0.95。该量表与咨询满意度及所选方法的测量指标呈正相关。IQFP还与提供者的沟通行为相关，包括引出患者观点和表达同理心。
IQFP量表在测量避孕咨询人际质量方面显示出结构效度、收敛效度、区分效度和预测效度。它有望作为一种可用于研究和质量改进工作的测量工具，以确保在计划生育护理中优先考虑患者的体验和偏好。
