Psychological birth trauma is closely related to maternal mental health, so identifying and evaluating the effectiveness of interventions are extremely important. There are many assessment tools for psychological birth trauma, but there is a lack of research evaluating the quality for them.

To systematically review the methodological quality and measurement properties of assessment tools of psychological birth trauma, so as to provide a reference for subsequent research.

PubMed, Web of Science, CINAHL, APA psycArticles, Embase, CNKI, Wanfang, VIP and CBM databases were searched on assessment tools of psychological birth trauma from the date of library construction to November 6, 2023. Literature screening, extraction and evaluation were conducted independently by 2 researchers and cross-checked.

Six literature involving six assessment tools for psychological birth trauma were included: the Birth Trauma Perception Assessment Scale (BTPS), the Maternal Childbirth Trauma Scale (MCTS), the Chinese version of the Traumatic Childbirth Perception Scale (TCPS-C), the Birth Trauma Scale (BTS), the Traumatic Childbirth Perception Scale (TCPS), and the Childbirth Trauma Index (CTI). None of assessment tools reported measurement error, cross-cultural validity, hypothesis testing, and responsiveness; In terms of content validity was "adequate" for the MCTS, TCPS-C, BTS, and TCPS, "uncertain" for the BTPS, and not reported for the "CTI"; In terms of structural validity, TCPS-C was "adequate", the remaining scales were "uncertain"; In terms of internal consistency, MCTS was "inadequate", the remaining scales were "adequate"; In terms of stability, BTPS, MCTS, and TCPS-C were "adequate", the remaining scales were "not mentioned". Ultimately, the recommendation grade for TCPS-C, BTS, and TCPS were A, and for BTPS, MCTS, and CTI were B.

TCPS-C, BTS and TCPS are valid assessment tools and can be provisionally recommended. However, their measurement properties and methodological quality are still inadequate, and this aspect can be further studied and continuously optimized in the future to improve the scientific and accuracy of the assessment tools and promote the development of related fields.

分娩心理创伤与孕产妇的心理健康密切相关，因此识别分娩心理创伤及评价干预效果极为重要。目前分娩心理创伤的评估工具较多，但尚缺乏评价其评估工具质量的研究。

系统评价分娩心理创伤评估工具的测量属性和方法学质量，为后续研究提供参考。

检索中国生物医学文献数据库、万方数据知识服务平台、中国知网、维普网、PubMed、Web of Science、CINAHL、Embase、APA PsycArticles中关于分娩心理创伤评估工具的相关研究，检索时限为建库至2023-11-06。文献筛选、提取与评价由2名研究者独立进行并交叉核对。

共纳入6项研究、6个评估工具：分娩创伤感知评估量表（BTPS）、产妇分娩创伤量表（MCTS）、中文版创伤性分娩感知量表（TCPS-C）、分娩创伤量表（BTS）、创伤性分娩感知量表（TCPS）、分娩创伤指数（CTI）。纳入评估工具均未报告测量误差、跨文化效度、假设检验及反应度；内容效度方面，BTPS为"不确定"，CTI未报告，其余量表为"足够"；结构效度方面，TCPS-C为"足够"，其余量表为"不确定"；内部一致性方面，MCTS为"不足"，其余量表为"足够"；信度方面，BTPS、MCTS和TCPS-C为"足够"，其余量表未报告。TCPS-C、BTS和TCPS为A级推荐，BTPS、MCTS和CTI为B级推荐。

TCPS-C、BTS和TCPS为有效评估工具，可暂被推荐，但其测量属性和方法学质量尚有不足，未来可进一步研究和持续优化，以提高评估工具的科学性和精准性，推动相关领域的发展。
