Gardner F, et al. - Researchers sought to examine how Incredible Years (a high-quality parenting program for reducing conduct problems) has influenced social equity by pooling individual-level trial data. They identified 15 European trials of Incredible Years parenting programs including 1,696 children aged 2–10 years, 492 of whom (30%) were from an ethnic minority and 931 (58%) of whom were from low-income families. Findings revealed child conduct problems decreased overall (13.5 points on the Eyberg Child Behavior Inventory Intensity scale) among families who received the Incredible Years intervention. Neither family disadvantage (indicated by poverty, lone parenthood, teenage parenthood, household joblessness, or low education) nor ethnic minority status were identified as having a differential impact. This suggests that Incredible Years did not widen socioeconomic inequalities in conduct problems. In addition, a reduction in social disparities and an improvement of poor long-term outcomes in disadvantaged families could be achieved with the program as benefits endured in follow-up studies. A similar efficacy of the program could be seen for families from different backgrounds.
