青少年执行功能量表的编制

目的 编制适用于考察青少年执行功能状况的量表.方法 根据执行功能的定义和结构成分,确定包含37个条目的初始量表,以分层抽样的方式选取来自全国2个省的1 722名青少年进行施测,分析量表的内部一致性信度、结构效度和效标效度.结果 编制成的青少年执行功能量表共21个条目,包含抑制控制、认知灵活性、工作记忆等3个维度,共解释方差的45.39％,因子载荷范围在0.499～0.727之间;量表及各因子的Cronbach＇sα系数在0.786～0.897之间;因子结构与实际数据相契合,其拟合指数分别为x2=530.44、df=186、RESMA=0.053、GFI=0.93、AGFI=0.91、NFI=0.96、CFI=0.97.结论 量表信效度良好,适合于评估我国青少年执行功能状况.

Development of adolescent executive function scale

Objective To develop a scale of the executive functional status for adolescents.Methods Regarding to the structure and the conception of executive function and the results of interviews to several adolescents,a preliminary inventory including 37 items was developed.The investigation sample consisted of 1722 students from 2 provinces in China by stratified sampling,and the the internal consistency,conduct validity and criterion validity were assessed by exploratory factor analysis.Results The revised scale including 21 items was consisted of three factors：inhibition control,cognitive flexibility,working memory,which explained 45.39％ of the total variance.The factor loading ranged from 0.499 to 0.727.The Cronbach alpha ranged from 0.786-0.897 for the scale and its three factors.Factor structure fitted actual data and its fit indices were x2=530.44,df=186,RESMA =0.053,GFI =0.93,AGFI =0.91,NFI =0.96,CFI =0.97.Conclusion It shows that the reliability and validity of the scale meet the standard of the psychometrics,and it can be suitable for evaluating the functional status of execution of Chinese adolescent.
