Gestational diabetes mellitus carries serious risks to mother and fetus and causes social, mental, and psychological consequences which can affect mothers' quality of life. Accordingly, this study aims to develop and assess the psychometric properties of quality of life questionnaire for women with gestational diabetes mellitus.
A methodological study of sequential exploratory mixed method was developed and implemented. It included qualitative (development of a quality of life questionnaire for mothers with GDM) and quantitative (assessment of psychometric prosperities of quality of life questionnaire for mothers with GDM) phases.
Based on the findings of the qualitative phase and literature review, the primary questionnaire was prepared with 142 items. The outcome of face validity and content validity assessment was a 67-item questionnaire. S-CVI and S-CVR turned out to be 0.92 and 0.68, respectively. The results of exploratory factor analysis yielded an instrument with 36 items in five domains including concerns about high-risk pregnancy, perceived constraints, disease complications, medication and treatment, and support. Five factors explained 46.68% of the total variance of the questionnaire. The results indicated a moderate and significant correlation between the questionnaire of "Diabetes Clients Quality Of Life" and the researcher-made questionnaire (r = 0.63). Cronbach's alpha coefficient for the entire scale was 0.93 and the intra-class correlation coefficient was 0.95.
Quality of life questionnaire for mothers with GDM is a valid and reliable tool capable of measuring the quality of life of women with GDM.
妊娠期糖尿病对母婴均有严重危害，可导致社会、心理和心理后果，影响母亲的生活质量。因此，本研究旨在开发和评估妊娠期糖尿病妇女生活质量问卷的心理测量特性。
采用序贯探索性混合方法进行了一项方法学研究。它包括定性（开发用于 GDM 母亲的生活质量问卷）和定量（评估用于 GDM 母亲的生活质量问卷的心理测量特性）阶段。
根据定性阶段和文献回顾的结果，编制了包含 142 个项目的初步问卷。通过表面有效性和内容有效性评估，得出了一个 67 项的问卷。S-CVI 和 S-CVR 分别为 0.92 和 0.68。探索性因素分析的结果得出了一个包含 36 个项目的五个领域的工具，包括对高危妊娠的担忧、感知限制、疾病并发症、药物治疗和支持。五个因素解释了问卷总方差的 46.68%。问卷与研究者制定的问卷之间存在中度显著相关性（r=0.63）。整个量表的克朗巴赫 α系数为 0.93，内部一致性系数为 0.95。
用于 GDM 母亲的生活质量问卷是一种有效且可靠的工具，可用于测量 GDM 妇女的生活质量。
