Although breast magnetic resonance imaging (MRI) is a valuable screening tool, breast MRI testing burden was associated with cancer worry and quality of life. We aimed to develop and validate the MRI-related distress scale (MRI-DS) to assess comprehensive distress specifically related to breast MRI.
We enrolled women aged above 18 years, diagnosed breast cancer, had MRI examination at least one time, and who could speak and read Korean in phase I and enrolled women aged above 18 years, visited outpatient clinic of breast general surgery, had undergone MRI examination at least once, and could speak and read Korean in phase II. We excluded patients who had any physical or psychiatric conditions in both phases. We recruited from a tertiary university-based hospital in South Korea between April and August 2023.
All 18 items had acceptable levels of item correlation (≥0.30) in the explanatory factor analysis with a four-factor solution. The fit indices for the four-factor solution model were good. The discriminant validity of the MRI-DS had a moderate correlation with general anxiety or quality of life. In the known-group analysis, those who reported MRI as the most burden breast examination had higher total scores.
The validity of the MRI-DS has been confirmed as a scale for measuring the specific distress caused by breast MRI. The MRI-DS is recommended to health professional to communicate with patients with MRI.
It can be used to assess the distress associated with MRI screening in breast cancer patients. Physician could use MRI-DS to discuss the reasons for distress caused by breast MRI screening and to address specific sources of discomfort associated with it.
尽管乳腺磁共振成像（MRI）是一种有价值的筛查工具，但乳腺 MRI 检查负担与癌症担忧和生活质量有关。我们旨在开发和验证 MRI 相关困扰量表（MRI-DS），以评估与乳腺 MRI 相关的综合困扰。
我们在第一阶段招募了年龄在 18 岁以上、被诊断患有乳腺癌、至少进行过一次 MRI 检查且能讲韩语和读韩语的女性，并在第二阶段招募了年龄在 18 岁以上、在乳腺普通外科门诊就诊、至少进行过一次 MRI 检查且能讲韩语和读韩语的女性。我们排除了在两个阶段都有任何身体或精神疾病的患者。我们在 2023 年 4 月至 8 月期间从韩国的一家三级大学附属医院招募了这些患者。
在解释性因素分析中，所有 18 个项目的项目相关性（≥0.30）都在可接受水平，具有四个因素的解决方案。四因素模型的拟合指标良好。MRI-DS 的判别有效性与一般焦虑或生活质量有中度相关性。在已知组分析中，那些报告 MRI 是最具负担的乳腺检查的人总得分更高。
MRI-DS 的有效性已被确认为衡量乳腺 MRI 检查引起的特定困扰的量表。建议医疗保健专业人员使用 MRI-DS 与接受 MRI 检查的患者进行沟通。
它可用于评估乳腺癌患者接受 MRI 筛查时的困扰。医生可以使用 MRI-DS 来讨论 MRI 筛查引起的困扰的原因，并解决与其相关的特定不适来源。
