Self-management of type 2 diabetes mellitus is crucial to controlling the disease and preventing harm. Multiple factors have been identified in the literature as potential barriers and facilitators to self-management, but the magnitude and directionality of these factors are seldom studied. We sought to develop and test an instrument to identify and quantify the barriers and facilitators to self-management of type 2 diabetes.
A community-centered approach was used to design, implement, and interpret the results of a stated-preference study. All activities were guided by a diverse stakeholder board. Based on previously reported development work, a novel survey instrument consisting of 13 potential barriers and facilitators was pretested and piloted in our local community. Participants were asked to discuss, rate, and rank each factor. A simple self-explicated method was used to quantify the data and Z scores were used for hypothesis testing.
In total, 25 patients with self-reported type 2 diabetes (64% female; 92% minorities) participated in the pretest and pilot. Time commitments (Z = -3.72), lack of active support groups (Z = -3.39) and other resources in the local community (Z = -2.96), and language/culture (Z = -2.69) were identified as barriers to self-management. Access to healthy food (Z = +5.68), personal understanding (Z = +4.81), and communication with healthcare providers (Z = +4.62) were identified as facilitators.
We demonstrate that factors impacting self-management can be quantified and categorized as barriers and facilitators. While further refinement to some factors and investigation into alternative prioritization methods is necessary, our stakeholder board endorsed moving this to a large nationally representative study to see how these factors vary across different people.
2 型糖尿病的自我管理对于控制疾病和预防危害至关重要。文献中已经确定了多个潜在的自我管理障碍和促进因素,但这些因素的大小和方向性很少被研究。我们试图开发和测试一种工具,以识别和量化 2 型糖尿病自我管理的障碍和促进因素。
采用以社区为中心的方法设计、实施和解释偏好声明研究的结果。所有活动均由多元化的利益相关者委员会指导。基于先前报告的开发工作,我们在当地社区预测试和试点了一种由 13 个潜在障碍和促进因素组成的新型调查工具。参与者被要求讨论、评分和对每个因素进行排名。使用简单的自我解释方法对数据进行量化,并使用 Z 分数进行假设检验。
共有 25 名自我报告患有 2 型糖尿病的患者(64%为女性;92%为少数民族)参与了预测试和试点。时间承诺(Z=-3.72)、缺乏活跃的支持小组(Z=-3.39)和当地社区的其他资源(Z=-2.96)以及语言/文化(Z=-2.69)被确定为自我管理的障碍。获得健康食品(Z=+5.68)、个人理解(Z=+4.81)和与医疗保健提供者的沟通(Z=+4.62)被确定为促进因素。
我们证明了影响自我管理的因素可以被量化和分类为障碍和促进因素。虽然需要进一步完善一些因素并研究替代的优先级方法,但我们的利益相关者委员会支持将其推进到一项大型全国代表性研究中,以了解这些因素在不同人群中的差异。
