背景：心理困扰在医学生中很常见，但表现形式多种多样。目前，还没有简单实用的工具，同时评估这些领域的困扰医学生。作者描述了受试者报告评估的发展（医学生幸福感指数，MSWBI）旨在筛选医学生的困扰在各种领域，并检查其初步的心理测量属性。相关领域的痛苦，确定，项目产生，并形成一个筛选工具，使用的过程中，文献综述，名义组技术，输入院长和医学生，以及与先前管理的评估的相关性分析。11名专家对项目的明确性、相关性和代表性进行了评判。计算内容效度指数（CVI）。使用调整概率一致性的成对一致性百分比评估评价者间一致性。数据从2248名医学生谁完成了MSWBI沿着与验证全长工具评估领域的兴趣被用来计算可靠性和探索内部结构validity.Results：倦怠（情绪衰竭和人格解体），抑郁，心理生活质量（QOL），身体生活质量，压力和疲劳被确定为包括在MSWBI领域。7个项目中有6个项目的项目CVI相关性和CVI代表性>= 0.82。总体量表的CVI相关性和CVI代表性分别为0.94和0.91。在清晰度、相关性和代表性方面，评分者之间的总体成对一致率>= 85%。Cronbach的α为0.68。逐项配对一致率和Phi均较低，表明项目之间几乎没有重叠。大多数的MSWBI项目有一个>= 74%的灵敏度和特异性检测范围内的预期domain.Conclusions：本研究的结果提供了证据的可靠性和内容相关的有效性的MSWBI。需要进一步的研究来评估剩余的心理测量特性并确定需要干预的分数。
Background: Psychological distress is common among medical students but manifests in a variety of forms. Currently, no brief, practical tool exists to simultaneously evaluate these domains of distress among medical students. The authors describe the development of a subject-reported assessment (Medical Student Well-Being Index, MSWBI) intended to screen for medical student distress across a variety of domains and examine its preliminary psychometric properties.Methods: Relevant domains of distress were identified, items generated, and a screening instrument formed using a process of literature review, nominal group technique, input from deans and medical students, and correlation analysis from previously administered assessments. Eleven experts judged the clarity, relevance, and representativeness of the items. A Content Validity Index (CVI) was calculated. Interrater agreement was assessed using pair-wise percent agreement adjusted for chance agreement. Data from 2248 medical students who completed the MSWBI along with validated full-length instruments assessing domains of interest was used to calculate reliability and explore internal structure validity.Results: Burnout (emotional exhaustion and depersonalization), depression, mental quality of life (QOL), physical QOL, stress, and fatigue were domains identified for inclusion in the MSWBI. Six of 7 items received item CVI-relevance and CVI-representativeness of >= 0.82. Overall scale CVI-relevance and CVI-representativeness was 0.94 and 0.91. Overall pair-wise percent agreement between raters was >= 85% for clarity, relevance, and representativeness. Cronbach's alpha was 0.68. Item by item percent pair-wise agreements and Phi were low, suggesting little overlap between items. The majority of MSWBI items had a >= 74% sensitivity and specificity for detecting distress within the intended domain.Conclusions: The results of this study provide evidence of reliability and content-related validity of the MSWBI. Further research is needed to assess remaining psychometric properties and establish scores for which intervention is warranted.
