Day One trains middle school, high school, and college students to be positive role models, ambassadors for healthy lifestyles, and informed and engaged members of their communities. Based on the social influence model, which has been determined by CSAP, NIDA, OJJDP, & US Department of Education as an effective prevention approach, youth are educated about public and community health issues - such as understanding the health impacts of poor diet, alcohol/drug use, and sedentary lifestyles - and how to effect positive, lasting change in their communities. Our program also covers techniques to resist social pressures, support others in making healthy choices, and determining positive alternatives. Youth are recruited from schools, youth groups, parks, recreation centers, parent-referrals, community organizations, and community events. The function of this program is to promote healthy lifestyles, advocate for social justice issues, and facilitate youth voice in community decision making, thereby empowering them as powerful catalysts for change within their respective social circles and communities.
