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.

阿拉巴马州育儿问卷 9：可靠性概括荟萃分析。

阿拉巴马州育儿问卷 9 (APQ-9) 是一种广泛使用的育儿行为的简短衡量标准。然而，APQ-9 的三个分量表的信度系数差异很大。对三个 APQ-9 分量表进行了可靠性概括元分析，以 (a) 估计平均内部一致性可靠性值和 (b) 检查方差来源。来自 31,572 名知情人、跨越 32 项研究的总共 113 个系数 alpha 被纳入该荟萃分析。结果显示了可接受的平均 α 值（积极养育的 0.84，不一致的纪律为 0.66，监督不力的子量表为 0.70）。调节分析结果发现，三个分量表的系数 αs 的差异受到许多变量的影响，包括管理形式、国家、语言版本、人口、分数的均值和标准差，以及样本量。我们的研究结果支持父母报告 APQ-9 作为一种有用的养育行为衡量标准的效用。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）。
