Abstract
Background and aim:
There is evidence that smoking cessation may improve depression and anxiety. We assessed the feasibility of implementing and trialling a smoking cessation intervention in services providing cognitive behavioural therapy (CBT) for common mental illness.
Design:
Pragmatic, two-armed, randomised, multicentre, acceptability and feasibility trial of a co-designed smoking cessation intervention (ISRCTN99531779).
Setting:
United Kingdom National Health Service (NHS)-funded services treating depression/anxiety across 4 NHS trusts.
Participants:
Adult daily smokers starting CBT for depression/anxiety (mean age 35.6 years (standard deviation [SD]=12.7), 89.6% white) who smoked 14.3 (SD=8.2) cigarettes/day with mean Generalised Anxiety Disorder questionnaire (GAD-7) and Patient Health Questionnaire 9 (PHQ-9) scores of 13.1 (SD=4.9) and 14.5 (SD=6.0). Sixty-eight participants were allocated to the treatment group and 67 to control.
Intervention/Control:
Both groups received CBT for depression/anxiety. The treatment group also received 12 sessions of integrated smoking cessation support. The control group was signposted to cessation services post-treatment.
Measurements:
Follow-up was at 3 and 6 months. The primary outcome was “study completion” by 3 months. Other outcomes included acceptability, satisfaction, feasibility, data completeness, and mental health.
Findings:
At 3 months, treatment did not affect study completion (odds ratio [OR] 0.81, 95% confidence interval [CI]: 0.31—2.09), did not harm mental health (PHQ-9 difference: coefficient 0.01, 95% CI: -2.19 to 2.22); GAD-7: coefficient 0.65, 95% CI: -1.59 to 2.90), but increased abstinence rates (OR 8.69, 95% CI: 1.11 to 396.26). Recruitment was acceptable, and key stakeholders were satisfied with the intervention.
Conclusions:
Among UK adult smokers receiving cognitive behavioural therapy (CBT) treatment for depression or anxiety, a smoking cessation intervention within the CBT treatment was well received, did not interfere with the primary treatment goals, and increased smoking cessation.
