Birth satisfaction represents a complex construct of implicit and profound relevance to a woman's perceived birth experience. It correlates with the childbearing woman's experience of the quality of care received and stress during labor. This study aimed to examine the psychometric properties of the Malay language version of the Women's Views of Birth Labour Satisfaction Questionnaire (WOMBLSQ) on labor satisfaction using the Rasch rating scale model.
A cross-sectional study was conducted. The translated Malay version of the WOMBLSQ was completed by 200 postpartum women in a tertiary hospital. The Rasch model was applied to investigate the statistics, unidimensionality, item polarity and misfit, person misfit and person item distribution map.
The Rasch analysis showed that the 27 items, in nine dimensions, had high item reliability and item separation at 0.98 and 7.65 respectively, while good person reliability and person separation were at 0.78 and 1.90, respectively. Item 6 ('My birth partner/husband couldn't have supported me any better') (outfit MnSq = 1.74, outfit z-std = 6.9, PtMea Corr = - 0.02) and Item 5 ('My birth partner/husband helped me to understand what was going on when I was in labor') (outfit MnSq = 1.65, outfit z-std = 2.9, PtMea Corr = 0.13) are misfit. Item 6 needs to be re-examined for removal or rephrasing, while Item 5 correlates poorly with the construct. Eight persons have the most misfitting response strings based on Item 6 but extremely trivial differences were found in the parameter estimates after refitting the model. Ten items easily endorse satisfaction from the respondents.
The WOMBLSQ tested among postpartum women has been shown to have a good person reliability index and a high item reliability index. Items 5 and 6 do not contribute in the construction of scale but not degrading and suggested for refining. The spread of item difficulty should be improved in the future modification of items.
分娩满意度是一个复杂的概念，与女性对分娩经历的感知质量密切相关。它与产妇在分娩过程中所经历的护理质量和压力有关。本研究旨在使用 Rasch 评分量表模型检验马来语版产妇分娩满意度问卷（WOMBLSQ）在分娩满意度方面的心理测量特性。
进行了一项横断面研究。在一家三级医院，200 名产后妇女完成了马来语翻译版的 WOMBLSQ。应用 Rasch 模型调查了统计数据、单维性、项目极性和不拟合、个体不拟合和个体项目分布图。
Rasch 分析显示，27 个项目分为 9 个维度，具有高项目可靠性和项目分离度，分别为 0.98 和 7.65，而良好的个体可靠性和个体分离度分别为 0.78 和 1.90。项目 6（“我的分娩伴侣/丈夫不能更好地支持我”）（拟合 MnSq=1.74，拟合 z 标准差=6.9，PtMea Corr=-0.02）和项目 5（“我的分娩伴侣/丈夫帮助我理解分娩时发生的事情”）（拟合 MnSq=1.65，拟合 z 标准差=2.9，PtMea Corr=0.13）不拟合。需要重新检查项目 6 以确定是否需要删除或重新措辞，而项目 5 与构建的相关性较差。基于项目 6，有 8 个人的反应字符串最不拟合，但在重新拟合模型后，参数估计值差异极小。10 个项目很容易得到受访者的满意。
在产后妇女中测试的 WOMBLSQ 已显示出良好的个体可靠性指标和较高的项目可靠性指标。项目 5 和 6 对量表的构建没有贡献，但也没有降低量表的信度，建议对其进行改进。在未来的项目修改中，应提高项目难度的分布。
