Abstract
Objective
The African Neuropsychology Battery (ANB) includes eight culturally appropriate cognitive tests developed for use in the Congo and other sub-Saharan African populations. The current study examines the reliability of the ANB in three samples of participants of African descent.
Methods
Subjects were recruited in the United States and the Congo to participate in three studies of ANB internal consistency reliability (Study 1), test–retest reliability (Study 2), and interrater reliability for the two ANB measures (i.e., Visuospatial Memory and Proverb Tests) requiring examiner ratings of response adequacy (Study 3). Subjects were administered ANB tests of visuospatial perception, language, memory, abstract reasoning, and problem solving. We calculated Cronbach’s alpha, corrected item-total correlations and mean inter-item correlations for internal consistency, Pearson product–moment correlations and intraclass correlation coefficients for test–retest reliability, and intraclass correlation coefficients for interrater reliability.
Results
The ANB tests had acceptable internal consistency (Cronbach’s alphas ranging from .37 to .93). Across subtests, test–retest reliability coefficients ranged from .39 to .91, and intraclass correlation stability coefficients (ICCs) ranged from .39 to .82. Of the two ANB tests requiring interrater reliability, only the Proverb Test had a low ICC of .13, (confidence intervals: −.29 to .52).
Conclusion
The present study demonstrated that most ANB tests show adequate reliability in participants of African descent. However, the scoring criteria of the African Proverb Test require revision in order to improve the interrater reliability of the measure.

非洲人后裔的非洲神经心理学电池的可靠性

摘要
客观的
非洲神经心理学电池 (ANB) 包括八种文化上适当的认知测试,用于刚果和其他撒哈拉以南非洲人口。目前的研究在三个非洲裔参与者样本中检验了 ANB 的可靠性。
方法
在美国和刚果招募受试者参加 ANB 内部一致性信度(研究 1)、重测信度(研究 2)和两种 ANB 测量(即视觉空间记忆和谚语测试)的评估者间信度的三项研究) 要求审查员对响应充分性进行评级(研究 3)。受试者接受了视觉空间感知、语言、记忆、抽象推理和解决问题的 ANB 测试。我们计算了 Cronbach's alpha、校正的项目总相关性和平均项目间相关性的内部一致性、Pearson 积矩相关性和重测信度的组内相关系数,以及评估者信度的组内相关系数。
结果
ANB 测试具有可接受的内部一致性(Cronbach's alphas 范围从 0.37 到 0.93)。在子测试中,重测信度系数范围为 0.39 至 0.91,组内相关稳定性系数 (ICC) 范围为 0.39 至 0.82。在需要评估者间可靠性的两项 ANB 测试中,只有 Proverb 测试的 ICC 较低,为 0.13(置信区间:-.29 至 .52)。
结论
本研究表明,大多数 ANB 测试在非洲裔参与者中显示出足够的可靠性。然而,非洲谚语测试的评分标准需要修改,以提高测量的跨度可靠性。
