This article outlines the development of the Perinatal Grief Intensity Scale (PGIS). It is based on a theoretical model developed to predict intensity of grief response to early pregnancy loss.
Participants completed the PGIS by mail and made an overall assessment of their grief intensity by completing a single Likert-type item.
A convenience sample of 186 women who had experienced a miscarriage before 16 weeks gestation in the previous 12-18 months.
Fourteen items were retained after factor analyses, loading at .4 or greater. The 14 items loaded on a three-factor solution as predicted and accounted for 65% of the variance. Three factors were found to influence intensity of grieving: Reality of the pregnancy and baby within (Reality), congruence between the actual miscarriage experience and the woman's standard of the desirable (Congruence), and the ability of parents to make decisions or act in ways to increase this congruence (Confront Others). Chronbach's alpha for the entire instrument was .82, with subscale reliability scores of .89 (Reality), .84 (Confront Others), and .71 (Congruence).
The PGIS demonstrates acceptable beginning reliability and validity in predicting grief intensity. Further testing of the instrument is needed with all types of pregnancy losses. The level of score needed to predict intense responses also needs to be determined.
本文概述了围产期悲伤强度量表（PGIS）的开发情况。它基于一个理论模型，该模型旨在预测对早期妊娠丢失的悲伤反应强度。
参与者通过邮件完成PGIS，并通过完成一个单一的李克特式项目对其悲伤强度进行总体评估。
选取了186名在过去12至18个月内经历过妊娠16周前流产的女性作为便利样本。
经过因子分析后保留了14个项目，载荷量为0.4或更高。这14个项目如预期那样加载到一个三因子解决方案中，解释了65%的方差。发现有三个因素影响悲伤强度：子宫内妊娠和胎儿的真实性（现实性）、实际流产经历与女性期望标准的一致性（一致性）以及父母做出决策或以增加这种一致性的方式行动的能力（面对他人）。整个量表的克朗巴赫α系数为0.82，各子量表的信度得分分别为：现实性0.89、面对他人0.84、一致性0.71。
PGIS在预测悲伤强度方面显示出可接受的初步信度和效度。需要对该量表进行针对所有类型妊娠丢失的进一步测试。还需要确定预测强烈反应所需的分数水平。
