Effectiveness of a mood management component as an adjunct to a telephone counselling smoking cessation intervention for smokers with a past major depression: a pragmatic randomized controlled trial.

摘要

AIMS: To assess whether the addition of a mood management component to telephone counselling produces higher abstinence rates in smokers with past major depression and helps to prevent recurrence of depressive symptoms. DESIGN: Pragmatic randomized controlled trial with two conditions, with follow-up at 6 and 12 months. The control intervention consisted of eight sessions of proactive telephone counselling. The mood management intervention was an integration of the control intervention with a mood management component. This component consisted of a self-help mood management manual, two more preparatory proactive telephone counselling sessions and supplementary homework assignments and advice. SETTING: Dutch national smoking cessation quitline. PARTICIPANTS: A total of 485 daily smokers with past major depression, according to the DSM-IV. MEASUREMENTS: The primary outcome measure was prolonged abstinence and secondary outcome measures were 7-day point prevalence abstinence and depressive symptoms. FINDINGS: The mood management intervention resulted in significantly higher prolonged abstinence rates at 6- and 12-month follow-up (30.5% and 23.9% in experimental condition, 22.3% and 14.0% in the control condition). The odds ratios were 1.60 (95% CI 1.06-2.42) and 1.96 (95% CI 1.22-3.14) for both follow-ups. The mood management intervention did not seem to prevent recurrence of depressive symptoms. CONCLUSIONS: Adding a mood management component to telephone counselling for smoking cessation in smokers with a past major depression increases cessation rates without necessarily reducing depressive symptoms.
