目的 检验儿童用家庭功能评估量表(FFAS-C)的信度和效度。方法 选取上海市7～12岁学龄期儿童2 931名,以年龄和年级为主要变量按比例分层抽样。所有儿童填写FFAS-C,家长填写家庭功能评估量表-总的功能(GF)。对255名儿童间隔21 d后以同样的程序对FFAS-C进行重测。结果 FFAS-C的Cronbach's α系数为0.808,各维度的内部一致性信度系数在0.603～0.729之间,量表各条目得分与量表总分的Pearson相关系数在0.431～0.607之间(P＜0.01),Spearman-Brown分半信度系数为0.822,Guttman分半信度值为0.815,重测相关系数为0.74(P＜0.01);探索性因子分析结果显示FFAS-C可以分为3个因子,使用验证性因子分析进行检验,三因子模型适配度较好;根据GF得分划分的GF高分组在FFAS-C总分和各维度得分均高于GF低分组(P＜0.01)。结论 FFAS-C具有较好的信度和效度。
Abstract
Objective To test the reliability and validity of the Family Functioning Assessment Scale for Children (FFAS-C).Methods A total of 2 931 children aged 7~12 years old in Shanghai were selected and stratified by age and grade as the main variables.All children filled out FFAS-C,their parents completed the Family Function Device-the General Function (GF).FFAS-C was retested with the same procedure after 255 days of interval.Results The Cronbach's α coefficient of FFAS-C was 0.808,and the internal consistency reliability coefficient of each dimension was between 0.603 and 0.729.The Pearson correlation coefficient of each item and the total score was between 0.431 and 0.607 (P＜0.01).Spearman-Brown half confidence coefficient was 0.822,Guttman half confidence was 0.815,the retest correlation coefficient was 0.74 (P＜0.01).The results of exploratory factor analysis showed that FFAS-C could be divided into three factors,which were verified by confirmatory factor analysis.The high-score group of GF was higher than those of score group-low of GF in the total score and each dimension score of FFAS-C (P＜0.01).Conclusion The FFAS-C has good reliability and validity.
