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 assess the reliability and validity of the SF-12 scale for evaluating children’s quality of life. Methods A total of 472 children aged 12-14 years were investigated by SF-12 scale. Among them, 175 were infected with major soil-borne nematodes (roundworms, hookworm, whipworm) and 297 were uninfected children. Evaluating the validity of the SF-12 scale using internal consistency reliability, discriminant validity, and structural validity Evaluating the validity of the SF-12 scale. Results The overall Cron-bach’α coefficient of SF-12 scale was 0.76. The Cronbach’s alpha coefficient of internal consistency scale of scales was between 0.678 and 0.778. The dimensions of unadulterated children and PCS and MCS scores (P <0.05). The results of factor analysis showed that there were 2 factors with the root> 1, and the cumulative contribution rate was 60.425%. Conclusion ST-12 universal scale for children with high reliability and validity, can be used for children’s quality of life in China.
