Depression is a leading mental health concern across the U.S. and worldwide. There are myriad assessments to evaluate depressive symptoms, including the Edinburgh Postnatal Depression Scale (EPDS), which is widely used to evaluate women's pre- and postnatal depression but not as prevalent at other timepoints in adulthood, limiting its utility for longitudinal research. As part of the National Institutes of Health's (NIH) Environmental influences on Child Health Outcomes (ECHO) Research Program, the current study sought to develop a common metric so that scores on the EPDS can be converted to the standardized Patient-Reported Measurement Information System (PROMIS®) T-score metric. Drawing on data from the ECHO-Prenatal Alcohol in SIDS and Stillbirth cohort, this study used a single-group linking design, where 1,263 mothers completed the EPDS and PROMIS-Depression measures at the same time. Score linking was conducted using equipercentile and item response theory (IRT) methods. Results showed both linking methods provide robust, congruent results, and subgroup invariance held across age, race, ethnicity, education, and geographic location. The IRT-based unidimensional fixed-parameter calibration was selected due to its model simplicity, and a crosswalk table was established to convert scores from the EPDS to PROMIS T-scores. Overall, this study provides a way to aggregate data across various depression measures and timepoints, such that researchers and clinicians now have the ability to directly compare and combine EPDS data with PROMIS and other depression measures already score-linked to PROMIS.

制定成年期抑郁症的通用衡量标准:将 PROMIS 抑郁症与爱丁堡产后抑郁量表联系起来。



抑郁症是美国乃至全世界主要的心理健康问题。有多种评估抑郁症状的方法,包括爱丁堡产后抑郁量表(EPDS),该量表广泛用于评估女性产前和产后抑郁,但在成年期其他时间点并不普遍,限制了其在纵向研究中的实用性。作为美国国立卫生研究院 (NIH) 环境对儿童健康结果 (ECHO) 研究计划的一部分,当前的研究旨在开发一个通用指标,以便 EPDS 的分数可以转换为标准化的患者报告测量信息系统(PROMIS®) T 分数指标。本研究利用 ECHO-产前酒精在 SIDS 和死产队列中的数据,采用单组关联设计,其中 1,263 名母亲同时完成了 EPDS 和 PROMIS-抑郁测量。使用等分位数和项目反应理论(IRT)方法进行分数关联。结果表明,两种关联方法都提供了稳健、一致的结果,并且在年龄、种族、民族、教育和地理位置方面保持了亚组不变性。由于模型简单,选择基于 IRT 的一维固定参数校准,并建立了人行横道表将 EPDS 分数转换为 PROMIS T 分数。总体而言,这项研究提供了一种汇总各种抑郁症测量值和时间点数据的方法,这样研究人员和临床医生现在就能够直接将 EPDS 数据与 PROMIS 以及其他已经与 PROMIS 评分相关的抑郁症测量值进行比较和结合。 (PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。
