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21d后以同样的程序对FFAS-C进行重测。结果 FFAS-C的Cronbach’sα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。
Objective To test the reliability and validity of FFAS-C for children. Methods A total of 2 931 school-aged children aged 7-12 years were selected, stratified by age and grade as the main variables. FFAS-C was filled for all children, and parents filled out the FAM - Total Functions (GF). FFAS-C was retested in the same procedure for 255 children after an interval of 21 days. Results The Cronbach’sα coefficient of FFAS-C was 0.808, and the reliability coefficient of internal consistency was between 0.603 and 0.729 in all dimensions. The Pearson correlation coefficient between each item of the scale and the total score of the scale was between 0.431 and 0.607 (P <0.01). Spearman-Brown’s half-confidence coefficient was 0.822, Guttman’s half-confidence value was 0.815, and 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, using confirmatory factor analysis to test the three-factor model is better fit; GF high score group according to the GF score in FFAS-C total score and each dimension score were higher than GF low score group (P <0.01). Conclusion FFAS-C has good reliability and validity.
