A team led by Bradley Collins, director of Temple's Health Behavior Research Clinic, found that door-to-door counseling helped new moms cut down on smoking. The team offered Philadelphia Family Rules for Establishing Smoke-free Homes, a 16-week intensive one-on-one counseling program for new mothers in North Philadelphia. "Our counselors explicitly demonstrated the steps one can take to create a smoke-free home and coached smokers through those steps taking into account individual and family-level factors that could either facilitate or undermine the behavior change process," Collins said.
