What should families learn when a parenting program changes some practices but not its main child outcome?
This rigorous real-world trial shows why respectful parenting programs must be evaluated rather than assumed successful: parenting changes did not translate into reduced child aggression.
Who was studied?
369 children with medium-to-high aggression from low-income households in southern Brazil
Age / stage: Young children; mean baseline age 3.1 years
Read with three questions
- What were the ACT, dialogic book-sharing and control conditions?
- Which results concerned the prespecified primary outcome of aggression?
- Which parenting benefits were temporary or program-specific?
Keep the limits in view
Neither program reduced the primary outcome of child aggression. Some parenting effects were small or not maintained; limited power for small effects and multiple outcomes constrain secondary findings.
