In response to the commentaries provided by Chu et al. (2020), Harmon et al. (2020), and McMahon & Maxwell (2020) on our longitudinal follow-up of Child-Parent Psychotherapy (CPP) with mothers with depression and their children, we focus on two domains: accessibility and scalability of CPP and identifying empirically supported mechanisms of change in attachment intervention research. In considering the accessibility and scalability of CPP, we discuss issues related to attrition, length of intervention, and implementation with caregivers with depression. Our discussion of mechanisms of change in attachment interventions explores active comparison conditions, theorized mediators, intervention modalities, assessment methods, and longitudinal research designs. This conversation is intended to highlight important areas for future research in the field of attachment interventions, with the goal of informing clinical and systems-level policies and practices.

回应 Chu 等人提供的评论。（2020），哈蒙等人。(2020) 和 McMahon & Maxwell (2020) 关于我们对患有抑郁症的母亲及其子女的儿童父母心理治疗 (CPP) 的纵向随访，我们关注两个领域：CPP 的可访问性和可扩展性以及确定经验支持的机制依恋干预研究的变化。在考虑 CPP 的可访问性和可扩展性时，我们与抑郁症护理人员讨论了与减员、干预时间和实施相关的问题。我们对依恋干预变化机制的讨论探讨了积极的比较条件、理论化的中介、干预方式、评估方法和纵向研究设计。
