Abstract：
OBJECTIVE: While there are various health literacy scales that exist, none of health literacy scale suitable for pregnant women with gestational diabetes mellitus (GDM). To address this gap, this study aimed to develop GDM health literacy scale and evaluate its psychometric properties.
METHODS: Based on the Delphi expert consultation, we developed the initial GDM health literacy scale. Item analysis was taken using a sample (n = 299) recruited in China to form formal scale. Additional participants (n = 395) completed survey to assess the internal consistency reliability, test-retest reliability, content validity, construct validity and criterion correlation validity of scale.
RESULTS: The scale performed well in terms of internal consistency reliability, content validity, construct validity and criterion correlation validity. Test-retest reliability indicated that the instrument was effective at measuring health literacy of GDM over time.
CONCLUSIONS: The scale is a reliable and valid measure of six domains of health literacy for GDM.
CONCLUSIONS: The scale can be used to effectively evaluate the level of health literacy of pregnant women with GDM. The information can provide targeted health support for pregnant women with GDM to improve their health literacy and self-management ability.

摘要：
目标：虽然存在各种健康素养量表，没有适合妊娠期糖尿病(GDM)孕妇的健康素养量表。为了解决这个差距，本研究旨在编制GDM健康素养量表并评价其心理测量特性。
方法：基于Delphi专家咨询，我们开发了最初的GDM健康素养量表。使用在中国招募的样本（n=299）进行项目分析，以形成正式量表。其他参与者(n=395)完成了评估内部一致性可靠性的调查，测试-重测可靠性，内容有效性，量表的结构效度和标准相关效度。
结果：量表在内部一致性可靠性方面表现良好，内容有效性，结构效度和标准相关效度。重测可靠性表明，该仪器可有效测量GDM的健康素养。
结论：该量表是GDM健康素养六个领域的可靠有效衡量指标。
结论：该量表可有效评价GDM孕妇的健康素养水平。该信息可为GDM孕妇提供有针对性的健康支持,提高其健康素养和自我管理能力。
