Mild deficits in instrumental activities of daily living (IADLs) have consistently been reported in the individuals with mild cognitive impairment (MCI). A variety of functional assessment tools, including self-and informant report questionnaires and performance-based measures, have been employed in MCI. Previously, a limited focus has been directed at appraising the quality of questionnaires. The goal of this study was to identify the questionnaires that have been validated in the MCI population. Additionally, the quality of validation studies and psychometric attributes of these questionnaires were appraised.
Relevant articles were systematically searched in PsychINFO, Ovid MEDLINE, and CINAHL against specific eligibility criteria. To evaluate the methodology of the psychometric studies, the COSMIN checklist was employed. Also, the psychometric properties of the assessment tools were evaluated based upon Terwee's criteria.
A total of five psychometric studies and questionnaires were critically evaluated. Varying psychometric properties were available for the chosen tools. None of the studies received the best possible rating for their methodological quality. It was found that questionnaires with high discriminative ability to distinguish MCI from other diagnostic groups were: Disability Assessment in Dementia-6 (DAD-6), Functional Activity Questionnaire (FAQ), and Alzheimer's Disease Cooperative Study/Activities of Daily Living scale adapted for MCI patients (ADCS-MCI-ADL-24).
Psychometric studies with strong methodological rigor are required in the future. Considering the fact that IADL decline has been associated with dementia, early detection of functional difficulties in MCI needs to be encouraged as it will allow suitable and timely interventions to prolong functional independence of affected individuals.
轻度认知障碍（MCI）患者中一直有关于日常生活工具性活动（IADL）轻度缺陷的报道。多种功能评估工具已用于MCI患者，包括自评和他人报告问卷以及基于表现的测量方法。此前，对问卷质量的关注有限。本研究的目的是识别在MCI人群中已得到验证的问卷。此外，还对这些问卷的验证研究质量和心理测量学属性进行了评估。
根据特定的纳入标准，在PsychINFO、Ovid MEDLINE和CINAHL中系统检索相关文章。为评估心理测量学研究的方法，采用了COSMIN清单。此外，根据Terwee标准评估评估工具的心理测量学特性。
共对五项心理测量学研究和问卷进行了严格评估。所选工具具有不同的心理测量学特性。没有一项研究在方法学质量上获得最佳评分。发现对区分MCI与其他诊断组具有高辨别能力的问卷有：痴呆症残疾评估-6（DAD-6）、功能活动问卷（FAQ）以及适用于MCI患者的阿尔茨海默病协作研究/日常生活活动量表（ADCS-MCI-ADL-24）。
未来需要开展方法学严谨性强的心理测量学研究。鉴于IADL下降与痴呆症相关，应鼓励早期发现MCI患者的功能困难，因为这将有助于采取适当及时的干预措施，延长受影响个体的功能独立性。
