精神疾病与生活中许多领域的不公平待遇有关。目前还没有开发出经过心理测量验证的措施来专门关注这种经历过的歧视。本研究旨在最终确定歧视和耻辱量表（DISC）并确定其心理测量特性。 DISC 通过 (1) 服务使用者和访谈员焦点小组得到进一步发展； (2)阅读难易度测试； (3) 认知汇报访谈。然后对修订后的量表进行心理测试，以确定以下属性：可靠性；有效性;精确;可接受性；和可行性。最终的 22 项 DISC 表现出良好的心理测量特性 (n=86)，包括评估者间可靠性（加权 kappa 范围：0.62-0.95）、内部一致性（alpha=0.78）和重测可靠性（n=46）（加权 kappa 范围：0.56-0.89）。还确定了可行性、有效性和可接受性。总之，建议使用包含 22 项的 DISC 来衡量所经历的耻辱和歧视。建议开展额外工作来制定预期耻辱的衡量标准。皇冠版权所有 (C) 2013 由 Elsevier Ireland Ltd 出版。保留所有权利。
Mental illness is associated with unfair treatment in a number of areas of life. There is currently no psychometrically validated measure that has been developed to specifically focus on such experienced discrimination. This study aimed to finalise the Discrimination and Stigma Scale (DISC) and establish its psychometric properties. The DISC was further developed using (1) service user and interviewer focus groups; (2) reading ease testing; and (3) cognitive debriefing interviews. The revised scale then underwent psychometric testing to establish the following properties: reliability; validity; precision; acceptability; and feasibility. The final 22-item DISC demonstrated good psychometric properties (n=86) including inter-rater reliability (weighted kappa range: 0.62-0.95), internal consistency (alpha=0.78) and test-retest reliability (n=46) (weighted kappa range: 0.56-0.89). Feasibility, validity and acceptability were also established. In conclusion, the 22-item DISC is recommended for use in measuring experienced stigma and discrimination. Additional work to develop a measure of anticipated stigma is recommended. Crown Copyright (C) 2013 Published by Elsevier Ireland Ltd. All rights reserved.
