The robustness of the diagnostic overshadowing bias was examined by (a) testing the relation of overshadowing to level of mental retardation, (b) reexamining the effect of clinical experience in a more sensitive analysis, and (c) extending previous results to rehabilitation counselors. Diagnostic overshadowing was found with individuals with an IQ of 58, but did not generalize to those with IQs 70 or 80. This finding does not support the saliency hypothesis proposed by Reiss and his colleagues. In contrast to earlier studies, experience was related to overshadowing, although results were mixed. Experience measured by number of clients seen was not significant, whereas longevity in the field of mental retardation was associated with increased overshadowing.
通过以下方式检验了诊断遮蔽偏差的稳健性
(a) 测试遮蔽与智力迟钝水平之间的关系；(b) 在更敏感的分析中重新审视临床经验的影响；(c) 将先前的结果扩展到康复顾问。在智商为58的个体中发现了诊断遮蔽现象，但并未推广到智商为70或80的个体。这一发现不支持赖斯及其同事提出的显著性假设。与早期研究不同，经验与遮蔽有关，尽管结果不一。以见过的客户数量衡量的经验并不显著，而在智力迟钝领域的工作年限与遮蔽增加有关。
