Abstract

Background

The Short Version of the Perinatal Grief Scale (SVPGS) is a widely used scale of grief related to perinatal loss. This study aims to validate and refine the SVPGS among Chinese women experiencing perinatal loss by addressing its psychometric properties.

Methods

After translating the SVPGS from English to Chinese and conducting a pre-test with 20 end-users, followed by an assessment of content validity involving 10 experts, a cross-sectional study was conducted to assess its internal reliability and structure, concurrent, convergent, divergent, known-group validities among 353 women who have experienced perinatal loss across eight hospitals in Hunan Province, China. A subset of 275 participants were reassessed over a 1-month interval for the test–retest reliability.

Results

The refined 15-item SVPGS demonstrated excellent internal consistency (Cronbach's α = 0.92) and strong 1-month test–retest reliability (κ = 0.83) compared to the original SVPGS. A three-factor structure consisting of 15 items was confirmed through item analysis, exploratory factor analysis, and parallel analysis. Confirmatory factor analysis further validated this structure, indicating a good fit for the refined SVPGS. Concurrent validity was supported by a large correlation between the SVPGS and refined SVPGS (r = 0.90, p < 0.01). Convergent and divergent validities were confirmed through significant correlations with variables including depressive symptoms, anxiety symptoms, and post-traumatic stress disorder, psychological flexibility, mindfulness, self-compassion, perceived social support, and quality of life. Known-group validation revealed significant differences in these variables between high and low levels of the refined SVPGS.

Conclusions

These findings indicate that the refined SVPGS is a brief, reliable, and valid tool for measuring grief in women who have experienced perinatal loss. Future research is strongly recommended to test the refined SVPGS across diverse samples and cultural contexts to enhance its generalizability.

中国肛周失禁妇女围产期悲伤简易量表的验证与完善：一项心理测量学研究

短版围产期悲伤量表（SVPGS）是一种广泛使用的围产期损失相关悲伤量表。本研究旨在通过分析其心理测量特征，验证和完善中国围产期丧失妇女的SVPGS。方法将SVPGS翻译成中文，对20名最终用户进行预测，随后对10名专家进行内容效度评估，对湖南省8家医院353名围产期流产妇女的内部信度和结构、并发效度、收敛效度、发散效度和已知组效度进行横断面研究。275名参与者的子集在1个月的间隔内重新评估测试-重测信度。结果改进后的15项SVPGS与原始SVPGS相比具有良好的内部一致性（Cronbach’s α = 0.92）和较强的1个月重测信度（κ = 0.83）。通过项目分析、探索性因素分析和平行分析，确定了一个由15个项目组成的三因素结构。验证性因子分析进一步验证了该结构，表明该结构很适合改进后的SVPGS。SVPGS与精炼SVPGS之间存在较大的相关性（r = 0.90, p < 0.01），支持并发效度。通过与抑郁症状、焦虑症状、创伤后应激障碍、心理灵活性、正念、自我同情、感知社会支持和生活质量等变量的显著相关，证实了趋同效度和发散效度。已知组验证显示，在高水平和低水平的精制SVPGS之间，这些变量存在显著差异。结论改进后的SVPGS量表是一种简单、可靠、有效的测量围产期产妇悲伤程度的工具。未来的研究强烈建议在不同的样本和文化背景下测试改进的SVPGS，以增强其普遍性。
