目的流体智力(GF)与执行功能(EF)相关，也被认为与结晶智力(GC)相关。本研究包括在临床实践中经常用于检查这种GF-EF关系的GF、GC和EF的代表性指标。假设GF-EF关系高于GC-EF关系，特别是工作记忆(作为EF的一种测量)对这种关系有很大的贡献。方法采用考夫曼青少年和成人智力测验和剑桥神经心理测验自动化成套测验的3项执行任务，对188名神经精神病学和非临床样本进行验证性因素分析，包括工作记忆、计划技能和定势转移。结果模型与数据拟合良好[χ2(2 4)=35.2 5，p=0.0 7，RMSEA=0.050]。GF与EF之间有很高的相关性(0.91)，其中工作记忆是最深刻的指标。GC与EF呈中度至高度相关。目前的研究结果与GF与工作记忆密切相关的发现是一致的。结论GF与EF高度相关。神经精神疾病患者的GF功能障碍需要进一步的EF检查，反之亦然。讨论结果证实有必要区分具体的和一般的流体/执行功能，当任务的复杂性和新颖性增加时，后者更加复杂。这种区分可以提供更精细的鉴别诊断，提高神经精神治疗的适应症。
Objective Fluid intelligence (Gf) has been related to executive functioning (EF) in previous studies, and it is also known to be correlated with crystallized intelligence (Gc). The present study includes representative measures of Gf, Gc, and EF frequently used in clinical practice to examine this Gf–EF relation. It is hypothesised that the Gf–EF relation is higher than the Gc–EF relation, and that working memory in particular (as a measure of EF) shows a high contribution to this relation. Method Confirmatory factor analysis was performed on a mixed neuropsychiatric and non-clinical sample consisting of 188 participants, using the Kaufman Adolescent and Adult Intelligence Test, and three executive tasks of the Cambridge Neuropsychological Test Automated Battery, covering working memory, planning skills, and set shifting. Results The model fitted the data well [χ2(24)=35.25, p=0.07, RMSEA=0.050]. A very high correlation between Gf and EF was found (0.91), with working memory being the most profound indicator. A moderate to high correlation between Gc and EF was present. Current results are consistent with findings of a strong relation between Gf and working memory. Conclusion Gf and EF are highly correlated. Gf dysfunction in neuropsychiatric patients warrants further EF examination and vice versa. It is discussed that results confirm the need to distinguish between specific versus general fluid/executive functioning, the latter being more involved when task complexity and novelty increase. This distinction can provide a more refined differential diagnosis and improve neuropsychiatric treatment indication.
