This study examined rates of objective cognitive and functional impairments and associations between cognitive performance and performance-based functional capacity in a well-characterized sample of adults experiencing homelessness.
One hundred participants completed a brief neuropsychological and functional capacity assessment and self-report questionnaires. Cognitive impairment rates were determined by comparing mean scores with published normative data, as well as by examining frequency of scores >1 SD below the mean. Pearson correlations were used to examine associations between cognitive and functional capacities.
Overall, 65% of the study participants had scores in the cognitively impaired range on a brief cognitive screening test, 30% had impaired processing speed, and 11% met cognitive criteria for intellectual disability. Furthermore, 48% of the sample met functional impairment criteria, and poorer cognitive performance was strongly associated with poorer performance-based functional capacity (p<0.001).
Cognitive and functional impairments are common among sheltered adults experiencing homelessness, underscoring the need for routine objective cognitive screening and rehabilitation services.
本研究在一个特征明确的成年无家可归者样本中，考察了客观认知和功能障碍的发生率，以及认知表现与基于表现的功能能力之间的关联。
100名参与者完成了一项简短的神经心理学和功能能力评估以及自我报告问卷。认知障碍发生率通过将平均得分与已发表的常模数据进行比较来确定，同时也通过检查得分低于平均值1个标准差的频率来确定。使用Pearson相关性分析来考察认知能力与功能能力之间的关联。
总体而言，在一项简短的认知筛查测试中，65%的研究参与者得分处于认知受损范围，30%的人处理速度受损，11%的人符合智力残疾的认知标准。此外，48%的样本符合功能障碍标准，认知表现较差与基于表现的功能能力较差密切相关（p<0.001）。
认知和功能障碍在受庇护的成年无家可归者中很常见，这突出了常规进行客观认知筛查和康复服务的必要性。
