Changes in parenting practices during Parent Management Training Oregon model with parents of children in foster care

This study examined changes in parenting practices among parents receiving Parent Management Training Oregon model (PMTO). These parents had children in foster care with serious emotional disturbance and were randomized to receive in-home PMTO for up to six months. Using data from the Parent Child Checklist, an observation-based measure administered by therapists after each parent-child session, latent growth curve modeling was conducted with a sample of 318 parents of children, aged 3–16years old, in foster care. Results showed that overall parenting effectiveness improved and that the change trajectory was best fit by a cubic model (two changes in trajectory). Parenting effectiveness initially increased but was found to turn downward temporarily, then rebounded toward additional improvements. Similarly, three of the six subscales – skill encouragement, positive involvement, and communication/monitoring – demonstrated significant change and a cubic trajectory. In contrast, problem solving and effective discipline subscales showed significant improvement but the trajectory was best fit by a quadratic model, indicating that these parenting practices improved and then leveled off near the end of treatment. The ineffective discipline subscale did not demonstrate significant change. Additionally, parents with high initial scores experienced lower rates of improvement and higher rates of deceleration. However, parents who started with relatively high rates of change were better able to maintain improvements over time. Overall, the results suggested PMTO was associated with increased effective parenting but the trajectory for positive change included both gains and setbacks. Future research is needed to determine whether gains in parenting practices are sustained beyond the treatment period.
