title: Effects of a School-based Intervention Program on Attitude and Knowledge of Household Members Towards a Smoke-free Home: a Cluster Controlled Trial.
abstract: BACKGROUND
  A school-based smoke free home (SFH) program is useful in empowering the mother and child to reduce secondhand smoke exposure but the effects of pretesting on knowledge and attitude has been largely ignored. We aimed to test whether such a program can be effective in Southern Thailand with an additional assessment of the net effect of the pretest.
  
  
  METHODS
  A Solomon four-group design was used. Twelve rural primary schools were assigned to one of the four conditions (each with 3 schools): intervention with and without a pretest, control with and without the same pretest. The intervention was performed in the classroom and home over a period of 1 month. Outcomes were assessed at baseline and 3 months after the intervention on whether the home was smoke free and related knowledge and attitude.
  
  
  RESULTS
  The intervention could lead to a smoke-free home without statistical significance. Attitude, knowledge and self-confidence on creating a smoke-free home, and self-confidence in avoidance of secondhand smoke exposure and persuading smokers to not smoke in their home were significantly improved. No pretest effect was observed.
  
  
  CONCLUSIONS
  Gain in attitude, knowledge and self-confidence among family members from the brief school-based education should be enhanced by other measures.
