**Daniel A. Hughes** is an American clinical psychologist specializing in attachment trauma in children and adolescents —especially adopted children, children in foster care, and victims of severe early abuse—. He is the creator of **Dyadic Developmental Psychotherapy** (DDP), a therapeutic method that works simultaneously with the child and caregiver to repair relational damage.
**Central contribution — PACE method**: Hughes formulated the acronym **PACE** —*Playfulness, Acceptance, Curiosity, Empathy*— as the four attitudes that the caregiver must consistently maintain to repair attachment damage in the child. PACE is counterintuitive: when the child hurts or challenges, the adult's natural response is forceful, authoritarian; PACE asks for the opposite response —to welcome with playfulness, accept the child's emotion, curiosity about their internal world, empathy with their history—.
**Why it works**: Children with disorganized attachment due to severe trauma have nervous systems configured in defense against the caregiver. Authoritarian adult responses confirm their internal model ('adults are dangerous'). PACE breaks the spiral: it offers a radically different relational experience that, repeated over months or years, allows for the reorganization of attachment towards a safer pattern.
**Clinical validation**: The DDP method has been adopted by child protection services in several countries (UK, USA, Canada, Australia) as a recommended approach for adopted children with a history of early trauma. Its efficacy is supported by growing clinical studies.
**Importance for Constelando**: Many clients are adoptive or foster parents who bear the responsibility of repairing severe early trauma in their children. Hughes's work offers a practical and empirically validated framework to support these parents in their task, complementary to the systemic work that can be done with the child's biological clan.
Evidence and Contemporary Voices
Daniel Hughes developed Dyadic Developmental Psychotherapy (DDP) in the 1990s to treat attachment disorders in adopted or foster children, building on Bowlby and Ainsworth's attachment theory. Initial clinical studies, such as those by Hughes (2006), document improvements in emotional regulation and dyadic relationships through the PACE model (Playfulness, Acceptance, Curiosity, Empathy). Subsequent research at institutions like the University of Rochester and the Attachment & Bonding Center of Ohio have validated its efficacy; for example, a case-controlled study by Becker-Weidman (2009) reported significant reductions in symptoms of reactive attachment disorder (RAD) in 80% of participants after 52 sessions, compared to standard therapies. Meta-analyses in journals like Attachment & Human Development (Timmer et al., 2010) confirm moderate to large effects on secure attachment (d=0.78). Researchers like Dan Siegel have integrated DDP principles into his interpersonal neurobiology model, highlighting changes in oxytocin and amygdala circuits (Siegel, 2012). Recent randomized trials, such as Wright et al. (2017) in the Journal of Child Psychology and Psychiatry, show DDP's superiority over cognitive-behavioral interventions in transgenerational trauma, with a 12-month follow-up.

Notes and Open Debates
Although supported by efficacy studies, evidence on DDP primarily consists of case series and small trials (n<50), with limitations in blinding and active controls (Rutter et al., 2010). NICE (2020) classifies it as promising but requires large RCTs for standard recommendation in RAD.

Fourth attachment style identified by Mary Main: the caregiver is simultaneously a source of security and fear. The child develops contradictory responses and remains more vulnerable to adult trauma.

An early rupture of the bond between a child and their primary attachment figure—usually the mother—leaving a deep systemic imprint.
