目的编制一个适合测量弱视儿童遮盖治疗的生活质量量表。方法参考国内外生活质量量表,编制遮盖治疗弱视儿童生活质量初始量表。应用该量表对88例接受遮盖治疗的7～12岁初诊弱视儿童进行治疗前后调查,采用离散程度法、因子分析法、相关系数法等6种方法联合进行条目筛选,由保留条目组建量表,并对该量表进行信度、效度以及反应度的评价。结果编制的遮盖治疗弱视儿童生活质量量表由16个条目组成,归属于视功能维度(6条)与社会心理维度(10条)。量表的重测信度为0.912;分半信度为0.907;Cronbach′sα系数为0.883。经因子分析,共提取4个公因子,累积方差贡献率为72.788%。效应尺度统计量为2.332。结论该量表具有较好的信度、效度和反应度,能够区分遮盖治疗前、后患儿生活质量之间的差异,可适用于临床评价遮盖治疗对弱视儿童生活质量的影响。
Objective To prepare a quality of life scale suitable for measuring the treatment of children with amblyopia. Methods With reference to the quality of life scale at home and abroad, the initial scale of quality of life for children with amblyopia was prepared. Eighty-eight children with amblyopia at the age of 7 to 12 years old undergoing occlusion therapy were surveyed by this scale before and after treatment. The items were screened by 6 methods including discrete degree method, factor analysis method and correlation coefficient method, , And the reliability and validity of the scale and evaluation of the degree of reactivity. Results The Quality of Life Scale for Children with Amblyopia was covered by 16 items, which belonged to visual function dimension (6) and social psychology dimension (10). The retest reliability of the scale was 0.912; the half reliability was 0.907; the Cronbach’s α coefficient was 0.883. By factor analysis, a total of four common factors were extracted, the cumulative variance contribution rate was 72.788%. The measure of effect scale is 2.332. Conclusion The scale has good reliability, validity and responsiveness. It can distinguish the difference between the quality of life before and after treatment, and is suitable for the clinical evaluation of the effect of covering therapy on the quality of life of children with amblyopia.
