目的 明确足功能指数(FFI)应用于儿童和青少年扁平足患者的信度和效度。
方法 2023年1月至2024年6月,于上海交通大学医学院附属第九人民医院3D打印接诊中心就诊的7~18岁扁平足患者中,挑选符合要求的患者41例作为观察组,纳入同期体检健康、正常发育、无任何足部问题的儿童和青少年56例作为对照组。所有参与者均填写FFI问卷。采用Cronbach α来确定FFI问卷的内部一致性。通过验证性因子分析观察问卷的结构效度。
结果 受试者的平均年龄为(12.99±3.19)岁。FFI的Cronbachs α系数为0.977,KMO值为0.914,模型拟合良好。总人群(7~18岁)、儿童组(7~13岁)、青少年组(14~18岁)主成分累计方差贡献率分别为93.967%、91.95%和96.91%。主成分分析得到3个主因子,所有条目的公因子方差均>0.70,因子载荷系数均> 0.40,每个公因子与变量之间有着较强关联性。
结论 FFI在评估儿童和青少年扁平足方面表现出良好的内部一致性信度和结构效度。
