Abstract

Problem

According to systematic literature reviews, most studies measured pregnant women's quality of life using generic measures.

Background

Condition-specific questionnaires are more sensitive and responsive than generic questionnaires. There is a great need to establish specific measures for assessing pregnant women's health-related quality of life considering their unique experiences of pregnancy.

Aim

To develop and test psychometric properties of the PregQOL, a health-related quality of life measure specific to pregnant women.

Methods

To construct the items of the PregQOL, we conducted semi-structured face-to-face interviews with five pregnant women in addition to an extensive literature review. For psychometric testing, data were collected with a convenience sample of 411 pregnant women. Construct validity was assessed via exploratory and confirmatory factor analyses. Convergent and known-groups validity were evaluated. Internal consistency reliability was studied using Cronbach's alpha and McDonald's omega. Test-retest reliability was examined.

Findings

After evaluation of content validity and exploratory/confirmatory factor analysis, the 24-item PregQOL was developed with four dimensions: daily functioning, supportive conditions, adaptation to pregnancy, and psychological well-being. It demonstrated convergent validity with relations to a quality of life measure for general population. Known-groups validity was supported by significant differences between the depressed and non-depressed groups. The scale demonstrated adequate internal consistency and test-retest reliability. It also showed good reliability across three trimesters of pregnancy.

Discussion

The newly developed PregQOL demonstrated good psychometric properties across three trimesters of pregnancy.

Conclusion

The PregQOL might be useful for helping midwives and other healthcare providers understand the overall well-being of pregnant women.

孕妇健康相关生活质量量表（PregQOL）：发展与心理测量评估

问题：根据系统的文献综述，大多数研究使用通用的测量方法来测量孕妇的生活质量。背景：特定条件调查问卷比一般调查问卷更敏感，反应更迅速。考虑到孕妇独特的怀孕经历，非常需要制定具体措施来评估她们与健康有关的生活质量。目的开发和测试孕妇健康相关生活质量指标PregQOL的心理测量特性。方法在广泛查阅文献的基础上，对5名孕妇进行半结构化的面对面访谈，构建妊娠生活质量量表。为了进行心理测试，我们收集了411名孕妇作为方便样本。通过探索性和验证性因素分析来评估结构效度。评估收敛效度和已知组效度。采用Cronbach's α和McDonald's ω研究内部一致性信度。检验了重测信度。结果经内容效度评估和探索性/验证性因子分析，编制了包含日常功能、支持条件、妊娠适应和心理健康四个维度的24项妊娠生活质量量表。它证明了与一般人群生活质量测量的关系的收敛有效性。已知组效度在抑郁组和非抑郁组之间有显著差异。量表具有足够的内部一致性和重测信度。它在怀孕的三个月里也显示出良好的可靠性。新开发的PregQOL在妊娠三个月期间显示出良好的心理测量特性。结论妊娠生活质量可以帮助助产士和其他医疗服务提供者了解孕妇的整体健康状况。
