Abstract

INTRODUCTION:

Sleep disturbance is common among cigarette smokers and predicts smoking cessation failure.

AIMS:

The purpose of this study was to conduct a pilot test of whether provision of a sleep intervention might bolster smoking cessation outcomes among this vulnerable group.

METHODS:

Smokers with insomnia (N = 19) seeking smoking cessation treatment were randomly assigned to receive 8 sessions over 10 weeks of either: (1) cognitive-behavioural therapy for insomnia + smoking cessation counselling (CBT-I+SC; n = 9) or (2) smoking cessation counselling alone (SC; n = 10). Counselling commenced 4 weeks prior to a scheduled quit date, and nicotine patch therapy was also provided for 6 weeks starting on the quit date.

RESULTS:

There was no significant effect of counselling condition on smoking cessation outcomes. Most participants had difficulty initiating and maintaining smoking abstinence in that 7-day point prevalence abstinence rates at end of treatment (CBT-I+SC: 1/7, 14%; SC: 2/10, 20%) and follow-up (CBT-I+SC: 1/7, 14%; SC: 0/10, 0%) were low for both conditions. CBT-I+SC participants reported improvements in sleep efficiency, quality, duration and insomnia symptoms. Sleep changes were not associated with the likelihood of achieving smoking abstinence.

CONCLUSIONS:

This randomised pilot study suggests that behavioural interventions may improve sleep among smokers with insomnia, but a larger sample is needed to replicate this finding and evaluate whether these changes facilitate smoking cessation.
