This intervention research paper aims to fill the gap in intergenerational, adolescent, older adult, art therapy, place attachment, and street art research. By incorporating an analysis and synthesis of this literature, I have developed a new form of art therapy, “street art therapy”. This extensive research culminates in a proposed intergenerational art therapy intervention using street art, with the intention of fostering place attachment, and overall community safety. The first two steps of intervention research according to Fraser, Richman, Galinsky and Day (2009) are used to support this intervention, with the intent that it can be used to complete the remaining three steps of testing the intervention, evaluating and adjusting it based on the pilot and finalizing the intervention to be used at large. Considerations and Limitations are also described in the discussion section of this paper.
