Abstract

Introduction

The Multiple Errands Test (MET) is a complex, performance-based assessment that is useful for characterising the impact of impairments of executive function on everyday activities. However, performance variance amongst those without neurological pathology, and the impact of non-cognitive factors on this, requires further investigation.

Methods

This was a cross-sectional analytic study, conducted with a convenience sample of 40 neurologically intact community-dwelling Australian adults. Participants completed a hospital or shopping centre version of the MET, where their Performance Efficiency, Task Completions and Rule Breaks were recorded. Non-cognitive factors of interest were demographic (age, sex and education), psychological (measured with the Hospital Anxiety and Depression Scale and self-ratings of test anxiety) and assessment-related (assessment site, self-reported site familiarity and observed strategy use). MET performance was analysed using descriptive statistics. A series of standard multiple and binary logistic regression analyses examined the relationships between MET performance and non-cognitive factors.

Results

Most participants (n = 35, 87.5%) completed at least 10 of the 12 prescribed tasks and broke an average of four rules (SD = 2.36). They achieved an average performance efficiency rating of 0.75/1 (SD = 0.15), suggesting variability in the extent to which participants made non-essential location stops and/or failed to complete tasks whilst at an essential location. The assessment site and participant site familiarity had a statistically significant (p < 0.05) impact on Performance Efficiency and Task Completion scores, and psychological factors had a statistically significant (p < 0.05) relationship with Rule Breaks.

Conclusion

Findings suggest that the impact of factors other than cognition should be considered when interpreting MET performance. The assessment site and participant site familiarity may contribute to significant variability in Performance Efficiency scores. Clinicians should also be aware of the potential impact of these assessment-related factors on Task Completions and psychological distress on Rule Breaks.

进一步调查多重差事测试的性能差异。

多重任务测试(MET)是一项复杂的、基于表现的评估，有助于描述执行功能障碍对日常活动的影响。然而，没有神经病理的人的表现差异，以及非认知因素对其的影响，需要进一步研究。方法:这是一项横断面分析研究，对40名神经系统完好的澳大利亚社区成年人进行了方便样本。参与者完成了医院或购物中心版本的MET，在那里他们的绩效效率、任务完成情况和违规行为被记录下来。感兴趣的非认知因素是人口统计学(年龄、性别和教育程度)、心理(用医院焦虑和抑郁量表和考试焦虑的自我评定来测量)和评估相关(评估地点、自我报告的地点熟悉程度和观察到的策略使用)。使用描述性统计分析MET性能。一系列标准多元和二元逻辑回归分析检验了MET表现与非认知因素之间的关系。结果:大多数参与者(n = 35, 87.5%)完成了12项规定任务中的至少10项，平均违反了4项规则(SD = 2.36)。他们获得了0.75/1 (SD = 0.15)的平均绩效效率评级，这表明参与者在非必要地点停留和/或在必要地点未能完成任务的程度存在差异。结论:研究结果表明，在解释MET表现时，应考虑认知以外因素的影响。评估地点和参与者对地点的熟悉程度可能会导致绩效效率得分的显著差异。临床医生还应该意识到这些评估相关因素对任务完成和违反规则的心理困扰的潜在影响。

期刊介绍： The Australian Occupational Therapy Journal is a leading international peer reviewed publication presenting influential, high quality innovative scholarship and research relevant to occupational therapy. The aim of the journal is to be a leader in the dissemination of scholarship and evidence to substantiate, influence and shape policy and occupational therapy practice locally and globally. The journal publishes empirical studies, theoretical papers, and reviews. Preference will be given to manuscripts that have a sound theoretical basis, methodological rigour with sufficient scope and scale to make important new contributions to the occupational therapy body of knowledge. AOTJ does not publish protocols for any study design The journal will consider multidisciplinary or interprofessional studies that include occupational therapy, occupational therapists or occupational therapy students, so long as ‘key points’ highlight the specific implications for occupational therapy, occupational therapists and/or occupational therapy students and/or consumers.
