Condensing parent training: A randomized trial comparing the efficacy of a briefer, more intensive version of Parent-Child Interaction Therapy (I-PCIT).

OBJECTIVE: The current study examined the comparative efficacy of a more intensive version of Parent-Child Interaction Therapy (I-PCIT; 5 days/week over 2 weeks) versus a time-limited weekly PCIT format (1 day/week over 10 weeks) in treating early childhood externalizing behavior problems. METHOD: = 30). Families completed pre-, post-, and follow-up assessments 6-9 months following treatment completion. Parents completed measures of child behavior, discipline practices, and parenting stress. Observational data on child behavior and parenting were also collected. RESULTS: Noninferiority and multivariate repeated-measures analyses indicated comparable improvements across 6 out of 7 observed and parent-reported outcomes, including parenting skills, discipline practices, and child externalizing behavior problems at posttreatment. Comparable treatment gains remained at follow-up, with the caveat that parents in time-limited PCIT reported lower externalizing behavior problems compared with I-PCIT, although both groups were still significantly better compared with pretreatment. Lastly, moderation analyses indicated that parents experiencing high levels of stress benefited more from I-PCIT in terms of decreasing child externalizing behavior compared with time-limited PCIT. CONCLUSIONS: I-PCIT appears to be a viable treatment option for families, especially those experiencing high levels of stress, in terms of targeting early externalizing behavior problems within a short period of time.
