Background

The Maternal Disintegrative Responses Scale (MDRS), which examines intrusive thoughts and dissociative experiences among mothers in the postpartum period, has recently been developed and initially validated.

Objective

In this series of two studies, we sought to further examine the validity and psychometric properties of the MDRS by confirming its factor structure and investigating its associations with insecure attachment and childhood trauma.

Participants and setting

Two convenience samples were recruited through social media. Participants in Study 1 consisted of 249 women aged 19 to 43 (M = 30.10, SD = 4.90) whose infants were up to 12 months old. Participants in Study 2 consisted of 637 women aged 20 to 46 (M = 31.43, SD = 4.81) whose infants were up to 16 weeks old.

Method

The participants completed a set of self-report questionnaires. In Study 1 we assessed trait anxiety, attachment orientation, the MDRS, and a background inventory. In Study 2 we assessed psychological distress, childhood trauma, the MDRS, and a background inventory.

Results

In both studies, the factor structure of the MDRS was confirmed. In addition, insecure attachment and childhood trauma were both related to the MDRS factors, above and beyond the woman's background characteristics and current level of anxiety or distress.

Conclusions

The studies indicate the value of the MDRS as a promising, valid, and theory-based questionnaire for mothers following childbirth.

母亲解体反应量表 (MDRS) 及其与依恋取向和童年创伤的关联

背景

最近开发并初步验证了母亲解体反应量表 (MDRS)，它检查产后母亲的侵入性想法和分离经历。

客观的

在这两项研究的系列中，我们试图通过确认其因素结构并调查其与不安全依恋和童年创伤的关联来进一步检验 MDRS 的有效性和心理测量学特性。

参与者和设置

通过社交媒体招募了两个便利样本。研究 1 的参与者包括 249 名 19 至 43 岁的女性（M  = 30.10，SD  = 4.90），其婴儿最大为 12 个月大。研究 2 的参与者由 637 名年龄在 20 至 46 岁（M  = 31.43，SD  = 4.81）的女性组成，她们的婴儿最大为 16 周大。

方法

参与者完成了一组自我报告问卷。在研究 1 中，我们评估了特质焦虑、依恋取向、MDRS 和背景清单。在研究 2 中，我们评估了心理困扰、童年创伤、MDRS 和背景清单。

结果

在这两项研究中，MDRS 的因子结构都得到了证实。此外，不安全依恋和童年创伤都与 MDRS 因素有关，超出了女性的背景特征和当前的焦虑或痛苦程度。

结论

研究表明 MDRS 作为分娩后母亲的有前途的、有效的和基于理论的问卷的价值。
