Overreporting has always been a concern within psychological evaluations. The Minnesota Multiphasic Personality Inventory-2-Restructured Form (Ben-Porath & Tellegen, 2008/2011 ) contains validity scales designed for detecting noncredible responses. In this study, 270 undergraduates were instructed to feign either schizophrenia, posttraumatic stress disorder (PTSD) or generalized anxiety disorder (GAD); some participants were coached on symptoms and validity scales. Results at both the individual protocol and mean validity scale score levels suggest that each feigned disorder moderates the effectiveness of coaching on validity scale detection. One finding of this study suggests that schizophrenia is generally more difficult to successfully feign than PTSD or GAD. Another finding suggests that the majority of individuals able to avoid detection as symptom overreporters are able to successfully endorse at least some disorder-relevant symptoms. We suggest that future research focus on the systematic exploration of other factors influencing the effectiveness of validity scales as well as the development of validity scales designed to detect the overreporting of internalizing forms of psychopathology.
过度报告一直是心理评估中的一个关注点。明尼苏达多相人格问卷-2 修订版（Ben-Porath 和 Tellegen，2008/2011）包含了旨在检测不可信反应的效度量表。在这项研究中，270 名本科生被指示假装患有精神分裂症、创伤后应激障碍（PTSD）或广泛性焦虑症（GAD）；一些参与者接受了症状和效度量表的辅导。个体协议和平均效度量表得分水平的结果表明，每种假装的疾病都能调节对效度量表检测的辅导效果。这项研究的一个发现表明，精神分裂症通常比 PTSD 或 GAD 更难成功地假装。另一个发现表明，大多数能够避免作为症状过度报告者被检测到的人能够成功地认可至少一些与疾病相关的症状。我们建议未来的研究集中系统地探讨影响效度量表有效性的其他因素，以及开发旨在检测内化型精神病理学过度报告的效度量表。
