Purpose: The aim of the current study was to examine and report three sources of reliability evidence for the Gibson Assessment of Cognitive Skills, a paper-based, brief cognitive screening tool for children and adults measuring working memory, processing speed, visual processing, logic and reasoning, and three auditory processing constructs: sound blending, sound segmenting, sound deletion along with work attack skills.
Sample and Methods: The sample (n = 103) for the current study consisted of children (n = 73) and adults (n = 30) between the ages of 6 and 80 (M = 20.2), 47.6% of which were female and 52.4% of which were male. Analyses of test data included calculation of internal consistency reliability, split-half reliability, and test–retest reliability.
Results: Overall coefficient alphas range from 0.80 to 0.94, producing a strong source of internal consistency reliability evidence. The split-half reliability coefficients ranged from 0.83 to 0.96 overall, producing a strong second source of reliability evidence. Across all ages, the test–retest reliability coefficients ranged from 0.83 to 0.98. For adults ages 18 to 80, test–retest reliability coefficients ranged from 0.73 to 0.99. For children ages 6 through 17, test–retest reliability coefficients ranged from 0.89 to 0.97. All correlations were statistically significant at p < 0.001, indicating strong test–retest reliability and stability across administrations.
Conclusion: The evidence collected for the current study suggests that the GACS is a reliable brief screening tool for assessing cognitive skill performance in both children and adults.
Keywords: cognition, memory test, reasoning test, intelligence test, reading skills

吉布森认知技能评估 (GACS) 的可靠性证据：筛查整个生命周期认知技能的简要工具
目的：本研究的目的是检查和报告 Gibson 认知技能评估的三个可靠性证据来源，这是一种基于纸质的简短认知筛查工具，用于儿童和成人测量工作记忆、处理速度、视觉处理、逻辑和推理，以及三种听觉处理结构：声音混合、声音分割、声音删除以及工作攻击技能。
样本和方法：本研究的样本（n = 103）包括 6 至 80 岁（M = 20.2）的儿童（n = 73）和成人（n = 30），其中 47.6% 为女性，其中男性占 52.4%。测试数据的分析包括计算内部一致性信度、分半信度和重测信度。
结果：总体系数 alpha 范围从 0.80 到 0.94，产生了内部一致性可靠性证据的强大来源。分半信度系数总体范围从 0.83 到 0.96，产生了强有力的第二个信度证据来源。在所有年龄段，重测信度系数范围从 0.83 到 0.98。对于 18 至 80 岁的成年人，重测信度系数范围为 0.73 至 0.99。对于 6 至 17 岁的儿童，重测信度系数范围为 0.89 至 0.97。所有相关性在 p < 0.001 时均具有统计学意义，表明在各管理部门之间具有很强的重测可靠性和稳定性。
结论：为当前研究收集的证据表明，GACS 是一种可靠的简短筛查工具，用于评估儿童和成人的认知技能表现。
