Effectiveness of the Swedish National Tobacco Quitline (SNTQ)

March 10, 2014 updated by: Uppsala University

Smoking Cessation by Telephone. Effectiveness and Cost-effectiveness of Proactive and Reactive Services at the Swedish National Tobacco Quitline (SNTQ).

The purpose of this study was to compare the effectiveness of the high-intensity proactive service with the low-intensity reactive service at the Swedish National Tobacco Quitline (SNTQ). Our hypothesis was that the effectiveness is about 5% higher in proactive than in reactive service.

The structured treatment protocol is a mixture of motivational interviewing (MI), cognitive behavior therapy, and pharmacological consultation.The standard process at the SNTQ is to offer the client a choice of callback (proactive service) or no callback (reactive service). In the present study clients were not offered a choice, but were randomized to proactive service on even dates and to reactive service on odd dates. Data are collected through postal questionnaires, one baseline and one follow-up after 12 months.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Proactive service
Intervention: Tobacco cessation by telephone support. The structured treatment protocol is a mixture of motivational interviewing (MI), cognitive behaviour therapy, and pharmacological consultation. In the proactive service the callers to the quitline are offered a number of callbacks.
Behavioral: Proactive service
In the proactive service the callers to the quitline are offered a number of callbacks.
Active Comparator: Reactive service
Intervention: Tobacco cessation by telephone support. The structured treatment protocol is a mixture of motivational interviewing (MI), cognitive behaviour therapy, and pharmacological consultation. In the reactive service the callers to the quitline are informed that they can themselves call back whenever they like.
Behavioral: Reactive service
In the reactive service the callers to the quitline are informed that they can themselves call back whenever they like.
