背景 弱视治疗指数（ATI）是一份家长问卷，在多项弱视治疗研究中已被用来评估遮盖或阿托品治疗对儿童和家庭的影响。包含 18 项的家长问卷设计有针对贴敷或阿托品治疗的版本。我们汇集了各个研究的数据，以进一步评估 ATI 的有效性，进一步评估因素（子量表）是否存在。方法 家长或监护人为 794 名儿童完成了 ATI，这些儿童参加了 4 项随机临床试验中的 1 项。采用Cronbach's alpha 评估内部一致性信度，并进行因子分析。结果ATI 表现出较高的内部一致性信度，Cronbach's alpha 为0.88（95% CL = 0.87, 0.89）。因素分析揭示了与原始验证研究中发现的相同的 3 个最小重叠因素，这些因素再次被标记为“不良反应”、“治疗依从性”和“社会耻辱”。其中两个 IS 项目没有加载我的因素，可以合理地从未来的 ATI 中删除。结论 ATI 是评估修补或阿托品治疗对儿童和家庭的影响的有用工具。 (J AAPOS 2008；12:581-584)
BACKGROUND The Amblyopia Treatment Index (ATI) is a parental questionnaire that has been used to assess the impact of patching or atropine treatment oil the child and family in several,amblyopia treatment studies. The 18-item parental questionnaire was designed with versions for treatment with patching or atropine. we pooled data across studies to further evaluate the validity of the ATI, to further assess the presence or absence of factors (subscales).METHODS A parent or guardian completed the ATI for 794 children who participated in 1 of 4 randomized clinical trials. Internal consistency reliability was assessed with Cronbach's alpha, and factor analysis was performed.RESULTS The ATI demonstrated high internal consistency reliability, with a Cronbach's alpha of 0.88 (95% CL = 0.87, 0.89). Factor analysis revealed the same 3 minimally overlapping factors found in the original validation Study, which were again labeled "adverse effects," "treatment compliance," and "social stigma." Two of the IS items did not load with,my factor and could reasonably be omitted from future ATI. administrations.CONCLUSIONS The ATI is a useful instrument for assessing die impact of patching or atropine treatment oil the child and family.
