Diabetes mellitus affects approximately 8.5% of the world's population with the majority of cases diagnosed with type 2 diabetes (T2DM). Impaired awareness or denial of T2DM is a common yet understudied construct that may negatively contribute to clinical outcomes. The aim of this study was to develop the Diabetes Awareness and Insight Scale (DAS), a self-report scale that measures illness awareness in persons with T2DM.
Nine items were developed for the DAS that measure four domains of illness awareness, namely General Illness Awareness, Accurate Symptom Attribution, Awareness of Need for Treatment, and Awareness of Negative Consequences attributable to T2DM (www.illnessawarenessscales.com). A total of 100 participants with a diagnosis of T2DM were recruited using a digital data collection platform.
The DAS demonstrated good convergent and discriminant validity, internal consistency, and one-month test-retest reliability. An exploratory factor analysis showed that the DAS exhibited three factors.
Overall, the DAS is a novel and easy-to-administer scale that comprehensively measures subjective illness awareness in persons with T2DM. As the first scale of its kind, the DAS holds promise for use in epidemiology studies to examine the extent to which impaired illness awareness or illness denial contributes to clinical outcomes and T2DM management.
糖尿病影响着全球约 8.5%的人口，其中大多数病例被诊断为 2 型糖尿病（T2DM）。T2DM 意识受损或否认是一种常见但研究不足的现象，可能对临床结局产生负面影响。本研究旨在开发糖尿病意识和洞察力量表（DAS），这是一种自我报告量表，用于衡量 T2DM 患者的疾病意识。
共开发了 9 个条目用于 DAS，用于测量疾病意识的四个领域，即一般疾病意识、准确症状归因、治疗需求意识和归因于 T2DM 的负面后果意识（www.illnessawarenessscales.com）。使用数字数据收集平台共招募了 100 名 T2DM 诊断患者。
DAS 表现出良好的聚合和区分效度、内部一致性和一个月的重测信度。探索性因素分析显示，DAS 表现出三个因素。
总体而言，DAS 是一种新颖且易于管理的量表，全面衡量 T2DM 患者的主观疾病意识。作为同类的首个量表，DAS 有望用于流行病学研究，以检验疾病意识受损或否认疾病在多大程度上影响临床结局和 T2DM 管理。
