The Alabama Parenting Questionnaire-9 (APQ-9) is a widely used brief measure of parenting behaviors. However, the reliability coefficients of the three APQ-9 subscales vary substantially. A reliability generalization meta-analysis was conducted on the three APQ-9 subscales to (a) estimate mean internal consistency reliability values and (b) examine the sources of variance. A total of 113 coefficient alphas from 31,572 informants, across 32 studies were included in this meta-analysis. Results showed acceptable mean α values (.84 for positive parenting, .66 for inconsistent discipline, and .70 for poor supervision subscales). Moderator analyses results found that differences in coefficient αs of the three subscales were influenced by numerous variables including administration format, country, language version, population, the mean and standard deviation of scores, and sample size. Our findings support the utility of the parent-report APQ-9 as a useful measure of parenting behaviors. Future research direction is also discussed.

阿拉巴马州父母调查问卷9：可靠性归纳荟萃分析。

阿拉巴马州育儿问卷9（APQ-9）是广泛使用的育儿行为的简短量度。但是，三个APQ-9子量表的可靠性系数存在很大差异。在三个APQ-9子量表上进行了可靠性归纳荟萃分析，以（a）估计平均内部一致性可靠性值，以及（b）检查方差的来源。这项荟萃分析包括来自32项研究的31,572名信息提供者的113个系数α。结果显示出可接受的平均α值（积极育儿为0.84，不一致的学科为0.66，不良监督子量表为0.70）。主持人的分析结果发现，这三个子量表的系数αs的差异受众多变量的影响，包括管理格式，国家/地区，语言版本，人口，分数的均值和标准差以及样本量。我们的发现支持将父母报告APQ-9用作育儿行为的有用度量。还讨论了未来的研究方向。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。
