To evaluate the psychometric properties and reliability of the Brazilian version of the tool Parent Attitudes about Childhood Vaccine (PACV-BR).
The sample included 110 parents of children up to two years old served by Family Health Basic Units. The tool's internal consistency and factor validity were respectively assessed by Cronbach's alpha and exploratory factor analysis (EFA). The test-retest reliability was assessed by the intraclass correlation coefficient (ICC).
The EFA results indicated a proper structural adequacy of the PACV-BR (15 items and two factors). The reliability generated Cronbach's alpha values between 0.715 and 0.854 for the items, of 0.918 for the tool as a whole, of 0.877 for factor 1 and of 0.825 for factor 2, in addition to an ICC of 0.984.
The PACV-BR showed evidence of construct validity and reliability.
评估工具《父母对儿童疫苗态度》（PACV-BR）巴西版本的心理测量学特性和信度。
该样本包括 110 名来自家庭健康基本单位服务的 2 岁以下儿童的家长。工具的内部一致性和因子有效性分别通过 Cronbach's alpha 和探索性因子分析（EFA）进行评估。测试-重测信度通过组内相关系数（ICC）进行评估。
EFA 结果表明 PACV-BR 具有适当的结构充分性（15 个项目和两个因素）。可靠性产生的 Cronbach's alpha 值在 0.715 到 0.854 之间，适用于各个项目，整个工具的 Cronbach's alpha 值为 0.918，第一个因素的 Cronbach's alpha 值为 0.877，第二个因素的 Cronbach's alpha 值为 0.825，此外，ICC 为 0.984。
PACV-BR 显示出了结构有效性和信度的证据。
