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.
The sample (n = 103) for the current study consisted of children (n = 73) and adults (n = 30) between the ages of 6 and 80 ( = 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.
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.
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.
本研究旨在检验并报告吉布森认知技能评估（Gibson Assessment of Cognitive Skills）的三种可靠性证据来源。该评估是一种纸质的简短认知筛查工具，用于儿童和成人，可测量工作记忆、处理速度、视觉处理、逻辑与推理，以及三种听觉处理结构：声音混合、声音分割、声音删除，同时还包括作业攻克技能。
本研究的样本（n = 103）包括6至80岁（平均年龄=20.2岁）的儿童（n = 73）和成人（n = 30），其中47.6%为女性，52.4%为男性。对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。
总体系数阿尔法值范围为0.80至0.94，产生了强有力的内部一致性信度证据来源。分半信度系数总体范围为0.83至0.96，产生了第二个强有力的信度证据来源。在所有年龄段中，重测信度系数范围为0.83至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时具有统计学意义，表明跨管理的重测信度和稳定性很强。
本研究收集的证据表明，吉布森认知技能评估量表（GACS）是一种可靠的简短筛查工具，可用于评估儿童和成人的认知技能表现。
