亲子互动量表的信度和效度检验

目的：检验亲子互动量表（Parent-Child Interaction Scales,PCI）的信度和效度。方法：于2020年11月—2021年1月在兰州市城区随机抽取814名0～3岁儿童及其家长进行调查，评价PCI中教育量表和喂养量表的信度和效度。结果：教育量表的Cronbach’sα系数为0.813，评分者信度为0.916，内部一致性信度为0.839，条目水平的内容效度指数（I-CVI）值为0.833～1.000，量表水平的内容效度指数（S-CVI/Ave）值为0.977，验证性因子分析结果显示拟合度良好；喂养量表的Cronbach’sα系数为0.912，评分者信度为0.873，内部一致性信度为0.923，条目水平的内容效度指数（I-CVI）值为0.833～1.000，量表水平的内容效度指数（S-CVI/Ave）值为0.991，验证性因子分析结果显示拟合度良好。结论：PCI量表具有良好的信度和效度，可以作为我国0～3岁儿童亲子互动质量的评估工具。

Reliability and Validity Tests of the Parent-Child Interaction Scale

OBJECTIVE To examine the reliability and validity of the Parent-Child Interaction Scale(PCI).METHODS A random sample of 814 groups of children aged 0~3 years and their parents were surveyed in urban areas of Lanzhou to evaluate the reliability and validity of the Education and Feeding Scale.RESULTS The Cronbach’s alpha coefficient of the PCI education scale was 0.813,the rater reliability was 0.916,the internal consistency reliability was 0.839,the content validity index(I-CVI)values at the entry level were 0.833~1.000,and the content validity index(S-CVI/Ave)values at the scale level were 0.977,and the validation factor analysis showed a good fit;the feeding the Cronbach’s alpha coefficient of the scale was 0.912 and rater reliability was 0.873,internal consistency reliability was 0.923 content validity index(I-CVI)values at the entry level were 0.833~1.000,and content validity index(S-CVI/Ave)values at the scale level were 0.991,and validated factor analysis showed goodness of fit.CONCLUSION The PCI scale had good reliability and validity and could be used as an assessment tool for the quality of parent-child interaction for children aged 0~3 years in China.
