| Despite robust research demonstrating that PCIT reduces child conduct problems (e.g.,
hyperactivity, aggression), limited research has validated PCIT’s effect on child psychosocial
competencies (e.g., attention regulation, prosociality). Thus, this study examined PCIT’s overall
and phase-specific effects on archival caregiver-ratings of conduct problems and psychosocial
competencies (overall and domain-specific; i.e., prosociality, compliance, attention regulation),
with a sample of 29 caregiver-child dyads (Mchild-age= 6.6; SDchild-age = 2.4) who received PCIT
and completed caregiver-report measures of their child’s psychosocial competencies (i.e.,
Psychosocial Strengths Inventory for Children and Adolescents; PSICA) and conduct problems
(Eyberg Child Behavior Inventory; ECBI) at pre-, mid-, and post-treatment. As predicted PSICA
and ECBI scores correlated significantly across all three time points (rs = -.62 to -.68), and child
conduct problems and psychosocial competence (overall and domain-specific) significantly
improved during PCIT (ηsp2 = .50–.86) and each of its phases (|d|s = 0.43–2.16). These findings
further validate PCIT’s transdiagnostic effects.
