Major factors that can affect the results of validation studies are identified and include reliability, homogeneity of sample, and criterion contamination. An overview and a description of content, predictive, concurrent, and construct validities are presented as well as a review of the recent studies of the validity of the Field Work Performance Report and the Certification Examination for Occupational Therapists. Adequate evidence of content and concurrent validity has been established for the Field Work Performance Report, although evidence for long-range predictive validity is lacking. Content validity alone has been established for the Certification Examination for Occupational Therapists. The evidence indicates that the instruments should not be abandoned, that they are better than no measures at all. The directions research might take in the future are given and the implications of continued use of the instruments are evaluated.
确定了可能影响验证研究结果的主要因素，包括可靠性、样本同质性和标准污染。本文概述并描述了内容效度、预测效度、同时效度和结构效度，还回顾了近期关于《实地工作表现报告》和职业治疗师认证考试效度的研究。尽管缺乏长期预测效度的证据，但已为《实地工作表现报告》确立了充分的内容效度和同时效度证据。职业治疗师认证考试仅确立了内容效度。证据表明，这些工具不应被摒弃，它们总比没有测量工具要好。给出了未来研究可能的方向，并评估了继续使用这些工具的影响。
