This study aims to develop the Quality of Life in Pregnancy Scale (PREG-QOL) as a new instrument to evaluate the quality of life during pregnancy and test its psychometric properties.
An instrument development study and psychometric testing of the content and construct validity, factor structure and reliability.
The study was conducted in three stages: (1) creating an item pool, (2) preliminary evaluation of items, and (3) refining the scale and evaluating psychometric properties. Instrument development guidelines were used to evaluate content validity, construct validity, internal consistency and stability of the instrument over time. Data to evaluate psychometric properties of the PREG-QOL were collected between April and August 2021.
Items were developed using in-depth interviews with pregnant women and extensive literature review. Scale-content validity index was 0.98. Exploratory factor analysis revealed a 26-item instrument with 6 factors, which explained % 56.2 of variance. Confirmatory factor analysis (CFA) showed that factors 3 and 5 should be combined into the factor of physical domain since they included items about the same theme. Fit indices obtained by CFA were at sufficient levels. Parallel test method was employed to evaluate the correlation of the PREG-QOL with the SF-36. The findings indicated that the PREG-QOL had high internal inconsistency and stability over time.
The PREG-QOL is a valid and reliable instrument in terms of its psychometric characteristics. The 26-item instrument was composed of the five factors of perception of general satisfaction, emotional domain, physical domain, health support systems and social domain.
Displaying good psychometric properties, the PREG-QOL may be used to evaluate multiple dimensions of the quality of life during pregnancy.
本研究旨在开发孕期生活质量量表（PREG-QOL），作为一种新的工具来评估孕期生活质量，并测试其心理测量学特性。
这是一项仪器开发研究和心理测量测试，用于评估内容和结构有效性、因素结构和可靠性。
研究分三个阶段进行：（1）创建项目池，（2）初步评估项目，以及（3）完善量表并评估心理测量学特性。仪器开发指南用于评估仪器的内容有效性、结构有效性、内部一致性和随时间的稳定性。用于评估 PREG-QOL 心理测量特性的数据于 2021 年 4 月至 8 月收集。
使用对孕妇的深入访谈和广泛的文献回顾开发了项目。量表内容效度指数为 0.98。探索性因子分析显示，一个 26 项的量表有 6 个因子，解释了方差的 56.2%。验证性因子分析（CFA）显示，因子 3 和 5 应合并为身体域的因子，因为它们包含了关于同一主题的项目。CFA 获得的拟合指数处于足够水平。采用平行测试法评估 PREG-QOL 与 SF-36 的相关性。研究结果表明，PREG-QOL 在心理测量学特征方面具有较高的内部一致性和随时间的稳定性。
从心理测量学特征来看，PREG-QOL 是一个有效且可靠的工具。由 26 个项目组成的量表包含五个因素：总体满意度感知、情绪域、身体域、健康支持系统和社会域。
PREG-QOL 具有良好的心理测量学特性，可用于评估孕期生活质量的多个维度。
