The Power of Positive Parenting provides an in-depth description of "Triple P," one of the most extensively studied parenting programs in the world, backed by more than 30 years of ongoing research. Triple P has its origins in social learning theory and the principles of behaviour, cognitive, and affective change, and its aim is to prevent severe behavioural, emotional, and developmental problems in children and adolescents by enhancing the knowledge, skills, and confidence of parents.

Triple P incorporates five levels of intervention on a tiered continuum of increasing strength for parents of children from birth to age 16.
