Alzheimer disease dementia may be preceded by cognitive stages during which behavioral and psychological changes can occur. More precisely, behavioral symptoms may be observed during the subjective cognitive decline (SCD) or the mild cognitive impairment (MCI) stages; these symptoms can be measured using the Mild Behavioral Impairment Checklist (MBI-C).
To validate the French-Quebec version of the MBI-C in individuals ages 60-85 years.
The sample included 60 participants (20 MCI, 20 SCD, 20 cognitively healthy) and their informants. To assess the discriminant validity of the MBI-C, a Kruskal-Wallis analysis with a multiple comparisons test was performed on the MBI-C Total score. To determine convergent validity, Spearman correlations were calculated between the MBI-C subscales and a set of validation tools. Finally, test-retest reliability was assessed with Spearman correlations of MBI-C scores between two test sessions.
All of the analyses indicated satisfactory psychometric properties for the French-Quebec version of the MBI-C.
This validation study reveals that the MBI-C can be used successfully in dementia risk assessments. From now on, the use of a validated MBI-C will be possible in the French-Quebec population.
阿尔茨海默病性痴呆之前可能存在认知阶段，在此期间可能会出现行为和心理变化。更确切地说，在主观认知下降（SCD）或轻度认知障碍（MCI）阶段可能会观察到行为症状；这些症状可以使用轻度行为损害检查表（MBI-C）进行测量。
验证60 - 85岁个体的魁北克法语版MBI-C。
样本包括60名参与者（20名MCI患者、20名SCD患者、20名认知健康者）及其 informant。为评估MBI-C的区分效度，对MBI-C总分进行了带有多重比较检验的Kruskal-Wallis分析。为确定收敛效度，计算了MBI-C各子量表与一组验证工具之间的Spearman相关性。最后，通过两次测试 session 之间MBI-C分数的Spearman相关性评估重测信度。
所有分析均表明魁北克法语版MBI-C具有令人满意的心理测量学特性。
这项验证研究表明，MBI-C可成功用于痴呆风险评估。从今以后，在魁北克法语人群中使用经过验证的MBI-C将成为可能。
