Attachment-based interventions with parent-child dyads constitute a clinical scenario characterized by a series of specific challenges and opportunities for intervention and, essentially, considerations with respect to technique which are novel in comparison with the classical psychoanalytic intervention model. This paper aims to highlight the common therapeutic elements that define and differentiate intervention with parent-child dyads. The common therapeutic elements that traverse these interventions are: specific consideration for and handling of the therapeutic alliance with parents; mentalization-centered interventions with parents; promoting parental sensitivity through self-observation; and modifying second-order parental representations. Insight-oriented interpretation through words or actions is also considered as a technique appearing among certain models of dyadic therapy. The rationale, implications and advantages of each of these therapeutic elements are explored and exemplified.
