Telephone-based Treatment for Smoking Cessation

Aim: to assess the effect of adding Motivational Interviewing (MI) to the existing smoking cessation treatment protocol at the Swedish National Tobacco Quitline (SNTQ).

Methods: Experienced counsellors at SNTQ either received further training in the standard treatment (ST) protocol (including Cognitive Behavioural Therapy (CBT)) or a comprehensive regime of training in MI. 1309 clients were randomized to either the ST group or the group with MI added to the treatment protocol. In order to ensure treatment integrity among counsellors, MI skill was assessed using the Motivational Interviewing Treatment Integrity Code (MITI).

Treatment and study plan

Standard treatment

Behavioral

Telephone-based smoking cessation counselling based on a combination of coaching and cognitive behavioural therapy (CBT) techniques. Counsellors are also trained in giving tailored advice regarding the use of smoking cessation aids.

Clients are offered a choice between "reactive treatment" (clients initiate all contact) and "proactive treatment" (counsellors call back at appointed dates). Printed information material tailored to clients' needs is offered free of charge.

Motivational Interviewing

Behavioral

Telephone-based smoking cessation counselling with Motivational Interviewing added to the standard treatment protocol.

Clients are offered a choice between "reactive treatment" (clients initiate all contact) and "proactive treatment" (counsellors call back at appointed dates). Printed information material tailored to clients' needs is offered free of charge.

Primary outcomes

  1. Point prevalence abstinence

    Time frame: 12 months after initial contact with SNTQ

    Not one puff of smoke during the previous 7 days

Secondary outcomes
