行为记录表作为婴幼儿气质评价工具的信度与效度

Reliability and validation of behavior record table as an infant temperament evaluation tool

目的探讨贝利婴幼儿发展量表中的行为记录表作为婴幼儿气质评价工具的信度与效度。方法根据经济状况在北京地区10个远郊区县采取分层随机整群抽样的方法选取了356名2～30个月的健康婴幼儿，并对每个婴幼儿进行贝利婴幼儿发展量表测试。对其中的行为记录表结果进行相关性分析，以检验信度；进行因子分析，以检验效度。数据资料采用SPSS15．0软件包作统计学处理。结果行为记录表的Cronbach仅信度系数为0．81，表明量表内部一致性较好、信度高。因子模型适应性分析KMO值0．651，巴特利球型检验P〈0．001，表明行为记录表的结果非常适合进行因子分析。因子分析共提取出5个公因子（特征值分别为6．707、2．943、1．719、1．578、1．368），累积方差贡献率达到69．316％，依次反映社会性、活动性、视听反应、心理活动、任务定向等5个气质维度。结论行为记录表具有良好的信度与效度，可作为婴幼儿气质评价工具在临床上使用。

Objective To investigate the reliability and validation of behavior record table in Bayley scales of infant development （BSID） as an infant temperament evaluation tool. Methods According to economic situations 356 healthy infants aged 2 - 30 months old were selected with stratified random cluster sampling method from 10 suburban districts and counties in Beijing, and Bayley scales of infant development were used to evaluate each infant. Correlation analysis was conducted on behavior records to inspect its reliability, and the validation was inspected by factor analysis. All data were statistically processed by SPSS 15.0 software package. Results Cronbach c~ reliability coefficient of the behavior record table was 0.81, which indicated good internal consistency and reliability of the behavior record table. In adaptive analysis of factor model, the value of KMO was 0.651 and the P value of Bartlett＇ s ball test was less than O. 001, which showed that the results of the behavior record table well suited for factor analysis. Five common factors were extracted through factor analysis （ characteristic value was 6. 707, 2. 943, 1. 719, 1. 578 and 1. 368, respectively）, and cumulative variance contribution rate was 69. 316%. They indicated orderly five temperament dimension as social, activity, audio-visual, psychological and task orientation. Conclusion With good reliability and validity, the behavior record table can be clinically used as an infant temperament evaluation tool.
