FIGURE 3—

Quit attempts, successful quitting, and nonspecific psychological distress: Assessing Hardcore Smoking Survey, Waves 1 and 2; 2004–2006.

Note. Those with nonspecific psychological distress (NSPD) were more likely to make a quit attempt than were those without NSPD but less likely to be successful. The figure is derived from probit regression, using data from a national sample of smokers (n = 751 for quit attempt analyses; n = 368 made a quit attempt and were included in the quit success analyses). We adjusted estimates for age, education, and gender. Error bars represent 95% confidence interval.
