The objective of this study was to examine the reliability and validity of the Dysfunctional Behaviour Rating Instrument (DBRI) in cognitively impaired older adults living in the community. A total of 184 adults with suspected cognitive impairment received a standardized history, physical examination and work-up that included the Standardized Mini-Mental State Examination. Caregivers scored a DBRI Behaviour Problem Checklist (BPC) and Lawton Scale for each patient. The reliability of the DBRI, measured by an intraclass correlation coefficient, was 0.75. The correlation coefficient between the DBRI and the BPC total score was 0.71. The correlations between the DBRI and the cognitive, activities of daily living and self-care domain scores of the BPC were lower (0.66, 0.38 and 0.26 respectively). The DBRI is a specific, reliable and valid caregiver-reported measure of dysfunctional behaviour in cognitively impaired elderly living in the community.
本研究的目的是检验功能失调行为评定工具（DBRI）在社区认知受损老年人中的信度和效度。共有184名疑似认知受损的成年人接受了标准化病史、体格检查及包括标准化简易精神状态检查在内的检查。照料者为每位患者对DBRI行为问题清单（BPC）和劳顿量表进行评分。通过组内相关系数测量的DBRI信度为0.75。DBRI与BPC总分的相关系数为0.71。DBRI与BPC的认知、日常生活活动和自我照料领域得分之间的相关性较低（分别为0.66、0.38和0.26）。DBRI是一种由照料者报告的、针对社区认知受损老年人功能失调行为的特异、可靠且有效的测量工具。
