Barriers to success in parent training for young children with developmental delay: the role of cumulative risk.
Three or more family risks predict PCIT dropout—add extra supports before session one.
01Research in Context
What this study did
The team tracked the families of preschoolers with developmental delay through standard Parent-Child Interaction Therapy.
They counted how many risk factors each family carried: low income, single parent, teen mom, mental-health history, domestic violence, and more.
Then they watched who finished the the study period and whose kids improved.
What they found
Families with three or more risks quit early twice as often.
Even the stayers saw smaller gains in child compliance and positive parenting.
Once risk hit three items, each extra risk doubled the chance of dropout.
How this fits with other research
Casey et al. (2009) flipped the script. They gave low-income Latino parents a Spanish-language class in their neighborhood center. Graduation and child gains were high, showing cultural tailoring can beat cumulative risk.
Cruz-Montecinos et al. (2024) echo the warning. Parents of kids with FASD kept using PBS tricks months later, but only when coaches stacked several antecedent tweaks. Extra supports, not bare-bones PCIT, made the difference.
Peskin et al. (2025) tried quick intake fixes like online screening. Forms got filled, yet graduation stayed flat. Their null result underlines M et al.'s point: surface tweaks don't touch deep family risk.
Why it matters
Screen every new family with a three-minute risk tally. When the count hits three, swap the standard PCIT script. Add flexible scheduling, Spanish materials, in-home warm-ups, or buddy parents. These low-cost patches can keep the highest-need families in the door and moving toward real behavior change.

03Original abstract
The purpose of this study was to examine the effect of cumulative risk on dropout and treatment outcome in parent training. Participants were 44 families of young children (mean age of 49.59 months) who presented with elevated externalizing behavior problems and developmental delay or borderline developmental delay. All families were offered to receive Parent-Child Interaction Therapy (PCIT), an evidence-based, behavioral parent-training intervention, at a hospital-based outpatient clinic. Cumulative risk was calculated as a sum of risk variables, including socioeconomic disadvantage (poverty, low maternal education), family structure (single-parent household), and maternal risk characteristics (minority status, lower intelligence, and parental distress). Families with higher cumulative risk scores, especially those with three or more risks, were more likely to drop out of treatment and display diminished treatment response in child behavior and parenting skills compared with families with lower cumulative risk scores. However, only two individual risk factors (i.e., minority status and family structure) predicted dropout, and one individual risk factor (i.e., maternal education) predicted outcome. These findings suggest that it can be useful to conceptualize risk factors as having a cumulative, in addition to individual, influence on parent-training interventions for children with developmental delay and have significant implications for clinical practice. It is important for clinicians to regularly assess for risk factors, and future research should examine ways in which clinicians can improve retention and outcome of parent training in the presence of multiple risk factors.
