Notes: Separate bivariate analyses were performed for the above-listed variables for only employed participants (n=297). Variables significant at p<0.20 were entered into a multivariate model (see Table 2); these included age, race, education, marital status, smoking status of the spouse/partner, encouragement to quit smoking by friends, smoking policy at work, nicotine dependence, number of cigarettes smoked per day, perceived vulnerability, prior chemotherapy, and radiation therapy. Variables that remained significant at p<0.15 were retained in the model.

^aHouseholds with no restrictions and partial restrictions were combined.

^bBased on only those who have a partner (n=177).

^cThe workplace can include the home setting.

CNS, central nervous system; GED, General Educational Development test; HS, high school; ns, not significant; Std, standard deviation.
