Adults who are homeless experience high rates of health conditions and psychological distress, including low IQ and functional status. Resources are available to help these individuals, but provision of support is often contingent upon the identification of a known disability. In this context, we examined case managers' (CMs') subjective estimates of IQ and functional status in 77 adult residents of an urban homeless shelter. Participants completed objective measures of IQ and functional capacity. CMs overestimated IQs of lower IQ (IQ < 90) participants, correctly estimated IQs of average IQ (IQ = 90-110) participants, and underestimated IQs of higher IQ (IQ > 110) participants. CMs correctly identified 2 out of 8 participants meeting criteria for intellectual disability and 4 out of 16 participants with impaired functional status. These findings suggest that subjective evaluations of IQ and functional status are prone to a central tendency bias, leading CMs to overlook clients who are in need of assistance. Consequently, the objective measurement of IQ and functional status in homeless shelters is highly recommended. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
无家可归的成年人经历着较高的健康状况和心理困扰的发生率，包括智商和功能状态较低。有资源可以帮助这些人，但提供支持通常取决于识别已知的残疾。在这种情况下，我们研究了城市无家可归者收容所的 77 名成年居民的个案经理（CM）对智商和功能状态的主观估计。参与者完成了智商和功能能力的客观测量。CM 高估了较低智商（智商 < 90）参与者的智商，正确估计了平均智商（智商 = 90-110）参与者的智商，低估了较高智商（智商 > 110）参与者的智商。CM 正确识别出符合智力障碍标准的 8 名参与者中的 2 名和功能状态受损的 16 名参与者中的 4 名。这些发现表明，智商和功能状态的主观评估容易受到中心趋势偏差的影响，导致 CM 忽视需要帮助的客户。因此，强烈建议在无家可归者收容所进行智商和功能状态的客观测量。（PsycInfo 数据库记录（c）2020 APA，保留所有权利）。
