RT Journal Article SR Electronic T1 A qualitative evaluation of 40 voluntary, smoke-free, multiunit, housing policy campaigns in California JF Tobacco Control JO Tob Control FD BMJ Publishing Group Ltd SP 491 OP 495 DO 10.1136/tobaccocontrol-2012-050923 VO 23 IS 6 A1 Travis D Satterlund A1 Jeanette Treiber A1 Robin Kipke A1 Diana Cassady YR 2014 UL http://tobaccocontrol.bmj.com/content/23/6/491.abstract AB Background Although it is legal for multiunit housing (MUH) property owners in all 50 states to prohibit smoking on their premises, including in individual units, MUH constitutes a relatively new setting to reduce exposure to secondhand smoke via voluntary smoke-free policy. This paper examines California state-funded smoke-free MUH policy campaigns between 2004 and 2010. Methods A cross-case analysis of 40 state-funded smoke-free MUH policy campaigns was conducted via an examination of final evaluation reports submitted to the California Tobacco Control Program. Results The most effective voluntary smoke-free MUH policy campaigns typically included: (1) learning the local [MUH] context, (2) finding and using a champion, (3) partnering with like-minded organisations, (4) building relationships with stakeholders, (5) collecting and using local data and (6) making a compelling case to decision makers. Discussions The aforementioned steps tended to be intertwined, and successfully securing voluntary smoke-free MUH policy required a strategic but flexible plan of implementation prior to entrance into the field. Campaigns designed to enhance voluntary smoke-free MUH policy adoption should underscore the economic viability of such policies during each strategic step.
