^aTwo-sample t test

^bChi-square test of association

^cAll 515 participants indicated whether one or more smokers was living in the home. However, four participants in the group with smoking in the home did not identify whether they were smokers.

Note. Because of rounding, percentages may not total 100.

Note. The potential range for health-related self-concept total scores is 8–56, with higher scores indicating greater health-related self-concept. The potential range for lung cancer worry is 3.8–16, with higher scores representing greater lung cancer worry. Perceived lung cancer risk was measured on a scale of 0–10, with higher scores indicating elevated risk. Perceived synergistic risk was measured on a scale of 1–5, with higher scores indicating elevated risk.
