Regressions control for age group. CI = confidence interval; COPD = chronic obstructive pulmonary disease; SD = standard deviation; TCA = Tobacco Control Act. Cronbach’s alpha for scaled health belief items: 0.75 (Mouth and throat cancer), 0.74 (Head and neck cancer), 0.86 (Bladder cancer), 0.81 (Respiratory illness in children), 0.87 (Clogged arteries), 0.78 (COPD), 0.69 (Emphysema and bronchitis), 0.78 (Erectile dysfunction), 0.82 (Amputation), 0.83 (Diabetes), 0.82 (Macular degeneration), and 0.84 (Cataracts).
