Recognition of the protective value of secure parent–child relationships has prompted a growing interest in parenting interventions informed by attachment theory. Circle of Security Parenting (COS-P) is one such program, specifically designed for scalability. Although widely disseminated internationally, evidence for the effectiveness of COS-P is very limited. This non-randomized controlled effectiveness study was designed to help address this gap. A sample of 256 parents of children aged 0–6 years was recruited from four community child and family health organizations. Assessments were undertaken pre- and post-intervention for the treatment group (n = 201) and at comparable times for the waitlist control group (n = 55). Analysis of data for mothers (89% of sample) revealed a significant Time x Group interaction for six of the seven outcomes examined. Compared to mothers in the control condition, treatment group mothers reported significantly: (a) improved parental mentalizing and self-efficacy regarding empathy and affection toward the child; (b) reduced caregiving helplessness and hostility toward the child; and (c) reduced depression symptoms, at the end of COS-P treatment. There was no difference between groups for change in perceived child difficultness. Within-treatment-group analyses indicated that mothers with older children reported greatest reductions in caregiving helplessness, and mothers with probable clinical depression pre-intervention reported greatest reductions in hostility and depression symptoms. Improvements in other study outcomes did not differ by depression severity or child age. Exploratory analyses indicated that treatment group fathers showed the same pattern of change as mothers. Clinical implications and directions for future research are discussed.

对安全的亲子关系的保护价值的认识促使人们对依恋理论指导下的父母干预产生了越来越大的兴趣。安全育儿圈（COS-P）就是这样一种程序，专门针对可伸缩性而设计。尽管在国际上广泛传播，但有关COS-P有效性的证据非常有限。这项非随机对照有效性研究旨在帮助解决这一差距。从四个社区儿童和家庭保健组织招募了256名0-6岁儿童的父母。在治疗之前和之后对治疗组进行评估（n  = 201），在等待时间的对照组进行评估（n = 55）。母亲数据（占样本的89％）的分析显示，在所检查的七个结果中，有六个时间与组之间存在显着的交互作用。与处于对照组的母亲相比，治疗组母亲的报告显着：（a）父母对孩子的移情和感情方面的心理和自我效能得到改善；（b）减少照料对儿童的无助和敌意；（c）在COS-P治疗结束后，抑郁症状有所减轻。两组之间在儿童感知困难方面的变化没有差异。治疗组内的分析表明，有大孩子的母亲报告的护理无助减少最大，而有可能在进行临床干预前进行抑郁症治疗的母亲报告的敌对和抑郁症状减少最多。其他研究结果的改善没有因抑郁症严重程度或儿童年龄而异。探索性分析表明，治疗组父亲表现出与母亲相同的变化模式。讨论了临床意义和未来研究方向。
