OBJECTIVES
Emotion dysregulation during pregnancy may impede women's capacity to navigate increased stressors during this period and may elevate risk for psychosocial impairment, especially for socioeconomically disadvantaged or racially marginalized women. Valid and efficient assessment of emotion dysregulation is needed.
METHODS
We used Item Response Theory (IRT) to examine the Difficulties in Emotion Regulation Scale (DERS) in 248 low income, primarily Latina/x pregnant women, to compare the short forms relative to the full DERS.
RESULTS
IRT indicated that the short forms exhibited modest reliability, but also indicated a substantial decrease in information (i.e., reliability) for the short forms compared with the full DERS. IRT indicated that the DERS-16 appeared more reliable (conserve more information) relative to the other short forms, the DERS-SF and DERS-18.
CONCLUSION
Findings suggest that clinicians and researchers use the full DERS when time permits and the DERS-16 when needing a briefer version.
目的
怀孕期间情绪失调可能会阻碍女性在这一时期应对增加的压力源的能力，并可能增加心理社会障碍的风险，尤其是对于社会经济地位不利或种族边缘化的女性。需要有效的情绪失调评估。
方法
我们使用项目反应理论（IRT）对 248 名低收入、主要是拉丁裔/怀孕的女性进行了情绪调节困难量表（DERS）的检测，以比较短形式与完整 DERS 的相对关系。
结果
IRT 表明，短形式具有适度的可靠性，但与完整的 DERS 相比，短形式的信息（即可靠性）也有较大的减少。IRT 表明，DERS-16 相对于其他短形式，即 DERS-SF 和 DERS-18，表现出更高的可靠性（保留更多的信息）。
结论
研究结果表明，临床医生和研究人员在时间允许的情况下使用完整的 DERS，在需要更简短的版本时使用 DERS-16。
