Adaptive behavior and intelligence are both essential components of defining and diagnosing intellectual disability. The exact relationship between these two constructs still warrants some clarification. Previous studies have examined the correlation between adaptive behavior and intelligence and have reported differing results. Overall, there seems to be agreement that a modest to moderate correlation exists between adaptive behavior and intelligence and that the strength of this relationship may increase as ability level decreases further below the population mean. Using the Diagnostic Adaptive Behavior Scale and a sample of 57 youth aged from 4 to 21 years old, we examined the correlation coefficients between the full-scale IQ scores and their scores obtained on conceptual, social, and practical adaptive skill domain scores, as well as the total adaptive behavior score. The results obtained indicated a modest to moderate correlation between adaptive behavior and intelligence. The strongest statistically significant correlation coefficient was between the full-scale IQ score and the conceptual adaptive skills domain score ( = 0.64). The correlation between the full-scale IQ score and the practical adaptive skills domain ( = 0.39) and social adaptive skills domain ( = 0.28; ns) were more modest. The correlation coefficient between the full-scale IQ score and the total adaptive behavior score also showed a moderate relationship with intelligence ( = 0.46). These findings are consistent with previous research, documenting that adaptive behavior and intelligence are two related but independent constructs. We discuss these findings and their implications.
适应性行为和智力都是定义和诊断智力障碍的重要组成部分。这两个概念之间的确切关系仍有待进一步阐明。以往的研究探讨了适应性行为与智力之间的相关性，报告的结果各不相同。总体而言，似乎大家一致认为适应性行为与智力之间存在适度到中等程度的相关性，并且随着能力水平进一步低于总体均值，这种关系的强度可能会增加。我们使用诊断适应性行为量表，对57名年龄在4至21岁之间的青少年进行了抽样调查，检验了全量表智商分数与他们在概念、社会和实践适应性技能领域得分以及总适应性行为得分之间的相关系数。所得结果表明适应性行为与智力之间存在适度到中等程度的相关性。统计学上最强的显著相关系数出现在全量表智商分数与概念适应性技能领域得分之间（= 0.64）。全量表智商分数与实践适应性技能领域（= 0.39）和社会适应性技能领域（= 0.28；无显著性差异）之间的相关性则较为适度。全量表智商分数与总适应性行为得分之间的相关系数也显示出与智力存在中等程度的关系（= 0.46）。这些发现与之前的研究一致，证明适应性行为和智力是两个相关但独立的概念。我们将讨论这些发现及其意义。
