Reliability and Validity of Adaptive Skill Rating Scale for Children

目的 :考察学龄期儿童适应技能评定量表的信度和效度。方法 :从同质性信度、重测信度、评定者一致性信度等方面进行信度检验。并对量表的结构效度和效标效度进行了检验。结果 :(1)各适应技能领域的Cronbach’sα系数在 0 .32～ 0 .99之间 ;分半相关系数为 0 .92～ 0 .99;各领域重测相关系数为 0 .76～ 0 .99,总分重测相关系数为0 .98;各领域评定者一致性系数为 0 .92～ 0 .99,总分评定者一致性系数为 0 .98。 (2 )因素分析结果表明该量表四个领域较多地负荷一个因子。 (3)适应技能总分与C -WISC的全量表相关系数为 0 .36 ,与儿童适应行为评定量表总分的相关系数为 0 .6 7。结论 :学龄期儿童适应技能评定量表的信、效度指标较为理想 ,基本符合心理计量学要求。

Objective:To investigate the reliability and validity of the Adaptive Skill Rating Scale for Children(ASRSC).Methods:The internal consistency reliability,test-retest reliability and inter-rater reliability were examined.A factor analysis procedure was used to explore the factor structure of ASRSC.The criterion-related validity was evaluated through correlating ASRSC with C-WISC and Child Adaptive Behavior Scale(CABS).Results:(1)Cronbach's α coefficents of the four domains of ASRSC ranged from 0.32 to 0.99;The split-half reliablity coefficients for four domains were 0.92～0.99;The test-retest reliability coefficient of the total score was 0.98;The interrater-reliability coefficient of the total score was 0.98;(2)One factor emerged following varimax rotation;The correlation between the total scores of ASRSC and C-WISC and CABS were 0.36,0.67 respectively.Conclusion:The reliability and validity of ASRSC were psychometrically acceptable.
