Abstract

Objective

We aimed to develop the health behaviour scale for gestational diabetes mellitus patients (HB-GDM) and evaluate its psychometric properties. The scale may provide theoretical basis and evidence for identifying the pathways to enhance health behaviours and optimise health management strategies.

Methods

The initial constructs and items of the scale were developed through literature review, qualitative analysis and Delphi expert consultation based on the socio-ecological model. Item analysis was conducted by four methods and using a sample (n = 235) recruited in China to form formal scale. Additional participants (n = 505) completed survey to measure the internal consistency reliability, test-retest reliability, content validity, construct validity and criterion-related validity of scale.

Results

The scale contains six dimensions with a total of 29 items. The Cronbach's α of the scale was 0.912, McDonald's ω of the scale was 0.936, test–retest reliability was 0.957, content validity was 0.935, The cumulative variance contribution rate of the six common factors was 77.488 % and CFA model had acceptable goodness-of-fit indices(χ²/df = 2.567, RMSEA = 0.079). The criterion-related validity was 0.827(P<0.01).

Conclusion

HB-GDM scale showed satisfactory psychometric properties and has strong specialisation and better applicability.

Practice implications

The scale is favourable for pregnant women with GDM to clarify their unhealth behaviours. It provided guidance regarding maternal and postpartum follow-up care and the formulation of women health care strategies with regional characteristics.

妊娠期糖尿病健康行为量表的编制与验证

目的编制妊娠期糖尿病（HB-GDM）健康行为量表，并对其心理测量特性进行评价。该量表可为确定增强健康行为和优化健康管理策略的途径提供理论依据和证据。方法以社会生态模型为基础，通过文献综述、定性分析和德尔菲专家咨询等方法编制量表的初始结构和项目。采用四种方法进行项目分析，并在中国招募样本（n = 235）形成正式量表。另外有505名被试完成问卷调查，测量量表的内部一致性信度、重测信度、内容效度、建构效度和标度相关效度。结果该量表包含6个维度，共29个条目。量表的Cronbach’s α为0.912,McDonald’s ω为0.936，重测信度为0.957，内容效度为0.935,6个常见因素的累积方差贡献率为77.488%，CFA模型具有可接受的拟合优度指标（χ2/df = 2.567, RMSEA = 0.079）。标准相关效度为0.827（P<0.01）。结论hb - gdm量表具有较好的心理测量性能，具有较强的专业性和较好的适用性。实践意义该量表有利于GDM孕妇明确其不健康行为。它就产妇和产后随访护理以及制定具有区域特色的妇女保健战略提供指导。

期刊介绍： The Journal of Psychosomatic Research is a multidisciplinary research journal covering all aspects of the relationships between psychology and medicine. The scope is broad and ranges from basic human biological and psychological research to evaluations of treatment and services. Papers will normally be concerned with illness or patients rather than studies of healthy populations. Studies concerning special populations, such as the elderly and children and adolescents, are welcome. In addition to peer-reviewed original papers, the journal publishes editorials, reviews, and other papers related to the journal''s aims.
