Yfoundations is the lead provider of sexual health capacity building training for the NSW youth workforce. Yfoundations Sticky Stuff training is funded through NSW Ministry of Health to increase the confidence and knowledge of health and youth workers to better engage young people around their sexual health. Young people are a priority population for sexual health interventions in NSW and front line workers are tasked with providing early intervention and preventative activity in addition to connecting young people with testing and treatment services. The evidence has shown that workers describe the need for further training and skill development to affectively achieve these outcomes. Sticky Stuff has trained over 800 workers across NSW over a two-year period and continues into 2016. It is evident through the results to date that capacity building workshops produce an immediate increase of knowledge and confidence as revealed by the results of pre and post training evaluations. This presentation will explore whether capacity building training programs produce lasting change as evidenced through long-term evaluations. It will examine the retention of knowledge and confidence and explore the extent to which practice has changed as a result of training. This presentation will also outline the training model used for state-wide training delivery and how key partnership between government and community sectors can be leveraged to impact communities.
