Self-perceived ability to cope with stress and depressive mood without smoking predicts successful smoking cessation 12 months later in a quitline setting: a secondary analysis of a randomized trial

Table 5 Multivariable logistic regression analyses^a for point prevalence abstinence and 6-month continuous abstinence

N = 214 Responders-only
Variable	Point prevalence abstinence^b		6-month continuous abstinence^c
Variable	OR (95% CI)	p	OR (95% CI)	p
Likelihood of being smoke-free in 1 year	1.00 (0.84–1.19)	0.985	1.04 (0.85–1.27)	0.695
Perceived ability to handle stress and depressive mood without smoking	1.18 (1.03–1.36)	0.017	1.20 (1.03–1.39)	0.020
Smoked in the week before baseline (ref. = yes)	3.28 (1.58–6.81)	0.001	3.93 (1.86–8.31)	< 0.001
N = 362 Including non-responders at follow-up (treated as smokers)
Variable	Point prevalence abstinence^d		6-month continuous abstinence^e
Variable	OR (95% CI)	p	OR (95% CI)	p
Likelihood of being smoke-free in 1 year	1.02 (0.88–1.19)	0.762	1.05 (0.88–1.25)	0.570
Perceived ability to handle stress and depressive mood without smoking	1.13 (1.00–1.27)	0.050	1.16 (1.01–1.33)	0.033
Smoked in the week before baseline (ref. = yes)	3.30 (1.79–6.09)	< 0.001	3.97 (2.01–7.83)	< 0.001

Variables shown in the table are the two self-perceived ability to cope variables and statistically significant variables
^aIncluded variables: gender, age, number of cigarettes/day, number of years of education, number of years smoked, smoking in the week before baseline, passive smoking, drug use, snus use, other support, likelihood of being smoke-free in 1 year, handle stress and depressive mood without smoking, and willingness to use pharmaceuticals
