A new indoor air / environmental health case study has recently been added to the Tools of Change website. "Clean Air at Home: Small Steps Make a Big Difference" is a targeted, community-based social marketing campaign that reduces young families' exposures to environmental contaminants at home such as mould, dust, fumes from toxic cleaners and tobacco smoke. The campaign uses an interpersonal approach that challenges tenants from social housing complexes to take five steps over five weeks to clean the air at home for their children's health. Almost three in four participants changed some of their behaviors and almost one half reported performing all five of the behaviors being promoted.
