Impact Results

Strong Evidence of Effectiveness

Power Through Choices was evaluated as part of the federal Evaluation of Adolescent Pregnancy Prevention Approaches (PPA) in collaboration with the Oklahoma Institute for Child Advocacy, and its independent evaluators at the University of Oklahoma Health Sciences Center and University of Nevada, Reno. PPA was a national evaluation funded by the Office of Adolescent Health within the U.S. Department of Health and Human Services to study the effectiveness of seven teen pregnancy prevention approaches. The PPA evaluation conducted random-assignment studies to provide rigorous evidence about program impacts, document implementation of the program and generate insights about the successes and challenges of delivering innovative teen pregnancy prevention programs.

Data collection and analysis was completed in the summer of 2015. The final Impact Evaluation Report was released in September 2016. The outcome findings documented a number of statistically significant changes in knowledge, attitude, intention, and behavior, providing strong evidence of effectiveness.

Key outcome findings at a 12-month follow-up survey among youth receiving Power Through Choices included:

  1. Increased knowledge about reproductive health issues and resources
  2. Lower sexual activity rates
  3. Less likely to have sex without protection
  4. Less likely to be involved in a pregnancy
