Abstract. Alexithymia can be defined as difficulties in describing one’s emotions and is of interest within clinical and developmental psychology as a potential mediating and exacerbating factor across multiple forms of psychopathology. Measuring alexithymia via self-reports can be challenging, as those with heightened alexithymia may have difficulties in recognizing their alexithymia traits due to impaired metacognitive skills. Thus, there would be considerable benefits to the availability of a psychometrically validated parent-reported alexithymia measure that may circumvent the issue of self-reports. We, therefore, examined the psychometric properties of a new parent-reported alexithymia measure, the Alexithymia Questionnaire for Children – Parent (AQC-P) in a community sample of 257 child-parent dyads. Furthermore, we examined the level of agreement between the parent-rated AQC-P and its self-rated counterpart, the Alexithymia Questionnaire for Children (AQC). Confirmatory factor analysis found that an oblique three-factor structure provided the best model for both AQC-P and AQC, with this structure showing measurement invariance across child gender. All subscales had omega internal consistency values > .70, supporting their reliability. Cross-informant consistency was supported by significant correlations between AQC and AQC-P scores. Results support the use of the AQC-P as a measure of parent-reported alexithymia in children.

父母报告的儿童述情障碍测量的心理测量验证

摘要。述情障碍可以被定义为难以描述自己的情绪，并且在临床和发展心理学中作为跨多种形式的精神病理学的潜在中介和恶化因素引起了人们的兴趣。通过自我报告测量述情障碍可能具有挑战性，因为那些患有述情障碍的人可能由于元认知技能受损而难以识别其述情障碍特征。因此，心理测量学验证的父母报告述情障碍测量的可用性将有相当大的好处，这可能会规避自我报告的问题。因此，我们在 257 个儿童-父母对的社区样本中检查了一项新的父母报告的述情障碍测量的心理测量特性，即儿童述情障碍问卷 - 父母 (AQC-P)。此外，我们检查了父母评定的 AQC-P 与其自评定的对应物儿童述情障碍问卷 (AQC) 之间的一致性水平。验证性因子分析发现，斜三因子结构为 AQC-P 和 AQC 提供了最佳模型，这种结构显示了跨儿童性别的测量不变性。所有分量表的欧米茄内部一致性值 > .70，支持其可靠性。AQC 和 AQC-P 分数之间的显着相关性支持了交叉信息一致性。结果支持使用 AQC-P 作为父母报告的儿童述情障碍的衡量标准。验证性因子分析发现，斜三因子结构为 AQC-P 和 AQC 提供了最佳模型，这种结构显示了跨儿童性别的测量不变性。所有分量表的欧米茄内部一致性值 > .70，支持其可靠性。AQC 和 AQC-P 分数之间的显着相关性支持了交叉信息一致性。结果支持使用 AQC-P 作为父母报告的儿童述情障碍的衡量标准。验证性因子分析发现，斜三因子结构为 AQC-P 和 AQC 提供了最佳模型，这种结构显示了跨儿童性别的测量不变性。所有分量表的欧米茄内部一致性值 > .70，支持其可靠性。AQC 和 AQC-P 分数之间的显着相关性支持了交叉信息一致性。结果支持使用 AQC-P 作为父母报告的儿童述情障碍的衡量标准。
