Review: stage based interventions did not influence smoking behaviour
Q Do stage based interventions change smoking behaviour in people who smoke?
35 databases from inception to July 2002, the internet, bibliographies of retrieved articles, and authors of relevant conference proceedings abstracts.
Study selection and assessment:
randomised controlled trials comparing stage based interventions with usual care or non-stage based interventions in influencing smoking behaviour in people who smoked. Stage based interventions emphasised a patient’s progression through 5 stages of the transtheoretical model (TTM) (precontemplation, contemplation, preparation, action, and maintenance). Study quality was assessed on the basis of randomisation, allocation concealment, blinding (participants, care providers, and outcome assessors), baseline comparability, adjustment for baseline differences, and follow up.
