Communities benefit from meaningful involvement by individuals of all ages, but adults don't always perceive youth as legitimate, crucial contributors to community decision-making processes. The purpose of the study reported here was to determine if adults who participated with youth in the Horizons program changed their attitudes, opinions, and behaviors when working with young people on community issues or projects. Results indicate a positive change in adult attitudes, opinions, and behaviors when working with youth following the Horizons program community conversations and leadership training.
