对认知功能进行简短、标准化、可靠且有效的自评测试可能有益于精神病学临床实践、研究和临床试验。 PROMIS (R) 应用认知能力量表由美国国立卫生研究院开发、评估和分发，用于测量感知的认知功能。本研究以成人和老年门诊患者样本 (N=148) 为样本，检验了 PROMIS (R) 应用认知能力八项和四项量表的信度和效度的多个方面。两种 PROMIS (R) 认知量表的内部一致性可靠性都很高。简短的四项目量表与完整的八项目量表高度相关（r(s)=0.98）。 PROMIS (R) 应用认知能力量表与抑郁 (PHQ-9) 和焦虑 (GAD-7) 测量值之间存在中等相关性。积极筛查抑郁或焦虑的参与者亚组报告的认知功能明显比医学对照差，且效应量较大。报告了抑郁、焦虑和对照参与者认可的单个项目的基本率。超过 42% 的抑郁和焦虑参与者报告了他们的记忆力和注意力问题，而医疗对照组中这一比例不到 8%。该领域将受益于在更多人口多样化样本中使用 PROMIS (R) 应用认知能力量表以及其他既定认知测量方法进行的研究。 (C) 2015 Elsevier Ireland Ltd. 保留所有权利。
Having a brief, standardized, reliable, and valid self-rated test of perceived cognitive functioning could be beneficial in psychiatry clinical practice, research, and clinical trials. The PROMIS (R) Applied Cognition-Abilities scales were developed, evaluated, and distributed by the National Institutes of Health to measure perceived cognitive functioning. This study examines several aspects of the reliability and validity of the PROMIS (R) Applied Cognition-Abilities eight and four-item scales in a sample of adult and older adult medical outpatients (N=148). Internal consistency reliability was high for both PROMIS (R) cognition scales. The brief four-item scale was highly correlated with the full eight-item scale (r(s)=0.98). There was a moderate correlation between the PROMIS (R) Applied Cognition-Abilities scales and measures of depression (PHQ-9) and anxiety (GAD-7). Subgroups of participants screening positively for depression or anxiety reported significantly worse cognitive functioning than medical controls, with large effect sizes. The base rates of individual items endorsed by depressed, anxious, and control participants are reported. More than 42% of depressed and anxious participants reported problems with their memory and concentration compared with fewer than 8% of medical controls. The field would benefit from studies using the PROMIS (R) Applied Cognition-Abilities scales in more demographically diverse samples and with other established measures of cognition.
