摘要
目的评估SF-12量表用于评价儿童生命质量的信度和效度。方法采用SF-12量表调查12～14岁儿童472名,其中感染主要土源性线虫(蛔虫、钩虫、鞭虫)儿童175人,未受感染儿童297人。使用内部一致性信度评估SF-12量表的信度,区分效度和结构效度评估SF-12量表的效度。结果 SF-12量表总的Cron-bach’sα系数为0.76,量表各维度内部一致性信度Cronbach’sα系数介于0.678～0.778之间;未受感染儿童各维度得分及PCS和MCS得分均高于中重度土源性线虫感染儿童,差别均有统计学意义(P<0.05);因子分析结果表明,抽取特征根>1的因素共有2个,累积贡献率为60.425%。结论 ST-12普适性量表用于儿童有较高的信度和效度,可以用于我国儿童生命质量研究。
Objective To access the reliability and validity of the SF-12 among children quality of life（QOL）.Methods Use SF-12 survey 472 children of 12-14 years old.175 were STH infections and 79 were moderate-to-heavy intensity infection.Reliability of the SF-12 was evaluated by internal consistency reliability,validity of SF-12 was evaluated by discriminant validity and structure validity.Results The internal consistency Cronbach＇s α efficient was 0.76.All domain＇s Cronbach＇s α range from 0.678-0.778.The score of all domains of control group were higher than that of moderate-heavy STH infection group.Two common factors which come from factor analysis almost consisted with theoretic structure,and the contributing rate of cumulative sums was 60.425%.Conclusions ShortForm-12（SF-12） Health Survey scale has a good validity and reliability,and it can be used for evaluate the quality life of the children.
