Outcomes of Childhood Preventive Intervention Across 2 Generations: A Nonrandomized Controlled Trial

Area of Science:

• Developmental Psychology
• Public Health
• Intergenerational Studies

Background:

• Preventive interventions in childhood have demonstrated long-term positive effects on behavioral and health outcomes into adulthood.
• Previous research indicates sustained benefits years after intervention completion.

Purpose of the Study:

• To investigate whether childhood interventions can yield sustained benefits across subsequent generations.
• To examine the outcomes in offspring whose parents participated in the Raising Healthy Children (RHC) intervention during elementary school.

Main Methods:

• A nonrandomized controlled trial involving 182 offspring (third generation) of parents who participated in the RHC intervention or a control group.
• Data collected from 1980 to 2011, with offspring assessed across 7 waves between 2002 and 2011.
• Intervention included classroom management, parent skills training, and child social-emotional skills development.

Main Results:

• Offspring of intervention parents showed improved early developmental functioning (ages 1-5).
• Lower teacher-rated behavioral problems and higher academic skills were observed in offspring (ages 6-18).
• Reduced risk behaviors, including substance use, were reported in offspring (ages 6-18).

Conclusions:

• This is the first study to report significant intergenerational intervention effects from a universal childhood preventive program.
• The findings suggest that the benefits of childhood interventions extend to the next generation, offering additional long-term value.
• Early life preventive programs may provide lasting advantages beyond the target generation.
