Primarily, to investigate the association between informant report and objective performance on specific financial capacity (FC) tasks by adults with chronic, moderate to severe acquired brain injury, and to examine the nature of misestimates by the informants.
Cross-sectional design.
A postacute, community-based rehabilitation center.
Data were obtained from 22 chronic acquired brain injury (CABI) adults, mean age of 46.6 years (SD = 8.67), mean years of education of 13.45 years (SD = 2.15), with moderate to severe acquired brain injury (86% had traumatic brain injury), with a mean postinjury period of 17.14 years (SD = 9.5). Whereas the CABI adults completed the Financial Competence Assessment Inventory interview-a combination of self-report and performance-based assessment, 22 informants completed a specifically designed parallel version of the interview.
Pearson correlations and 1-sample t tests based on the discrepancy scores between informant report and CABI group's performance were used. The CABI group's performance was not associated with its informant's perceptions. One-sample t tests revealed that informants both underestimated and overestimated CABI group's performance.
Results indicate lack of correspondence between self- and informant ratings. Further investigation revealed that misestimations by informants occurred in contrary directions with CABI adults' performance being inaccurately rated. These findings raise critical issues related to assuming that the informant report can be used as a "gold standard" for collecting functional data related to financial management, and the idea that obtaining objective data on financial tasks may represent a more valid method of assessing financial competency in adults with brain injury.
主要调查慢性中度至重度后天性脑损伤成人的特定财务能力（FC）任务的知情者报告与客观表现之间的关联，并检验知情者的估计错误的性质。
横断面设计。
一个康复后期的社区康复中心。
数据来自 22 名慢性后天性脑损伤（CABI）成年人，平均年龄 46.6 岁（SD=8.67），平均受教育年限 13.45 年（SD=2.15），中度至重度后天性脑损伤（86%有创伤性脑损伤），平均受伤后时间为 17.14 年（SD=9.5）。CABI 成人完成了财务能力评估清单访谈——自我报告和基于表现的评估相结合，22 名知情者完成了专门设计的访谈的平行版本。
使用基于知情者报告和 CABI 组表现之间差异得分的 Pearson 相关和 1 样本 t 检验。CABI 组的表现与其知情者的看法没有关联。1 样本 t 检验表明，知情者既低估了又高估了 CABI 组的表现。
结果表明自我和知情者评分之间缺乏一致性。进一步的调查显示，知情者的估计错误发生在与 CABI 成人表现相反的方向，并且 CABI 成人的表现被不准确地评估。这些发现提出了与假设知情者报告可以用作收集与财务管理相关的功能数据的“金标准”相关的关键问题，以及获得关于财务任务的客观数据可能代表评估脑损伤成年人财务能力的更有效方法的想法。
