Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary purpose of the current study is to compare the effect of SMS-textmessage vs e-mail reminders on user engagement and proportion of reported quit attempts in an online smoking cessation intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Web- and mobile phone health behavior change interventions, including smoking cessation programs, offer great promise, but little is known about how such interventions should be designed to increase user engagement. The primary purpose of the current study is to compare the effect of SMS-textmessage vs e-mail reminders on user engagement and proportion of reported quit attempts in an online smoking cessation intervention.

The investigators propose a 2-arm RCT with 700 adult study participants that all receive a best practices web-based smoking cessation program designed for use on smart phones (web-app). The intervention includes a ten day preparation phase, in which participants continue smoking. On the eleventh day (and onward) the user will receive a session in which (s)he is asked whether (s)he has quit smoking or not. If not, the user will receive additional treatment sessions until (s)he reports having quit (or dropped out of the study). Each day (for up to 14 days) a new unique session is assigned to the user. However, if the user does not log on to the web-intervention and starts using the session by noon on the second day after assignment, the user will receive a reminder to do so. When a user is to be sent a reminder for the first time, (s)he will be randomized to either receive such reminders by SMS or by e-mail.

The primary outcome is reporting a quit attempt or not. Secondary outcomes include number web-sessions started and completed and time spent navigating sessions after the first reminder is received.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants receive one out of two versions of a web-based smoking cessation program. The only difference between the two versions is the medium of the reminder: either SMS-textmessage or e-mail.
Primary Study Purpose

PREVENTION

Blinding Strategy

NONE

The recruitment procedure and the treatment is fully automated and delivered by web, e-mail and SMS-textmessages - i.e., the participant is not contacted by any care providers, investigators or assessors during recruitment or treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Online intervention with SMS reminder

Reminders will be sendt by SMS-TEXTMESSAGE if users of "Endre" does not log on to an assigned online session by noon on the second day.

Group Type EXPERIMENTAL

Endre

Intervention Type OTHER

The online intervention, "Endre", a digital smoking cessation counsellor that communicates with the user primarily through interactive web-sessions. Intervention content is tailored based on user input and individual usage pattern. Up to 14 unique sessions is assigned to the users during the study period, one each day. If a user does not start a session by noon on the second day a reminder will be sendt.

Online intervention with e-mail reminder

Reminder will be sendt by E-MAIL if users of "Endre" does not log on to an assigned online session by noon on the second day.

Group Type ACTIVE_COMPARATOR

Endre

Intervention Type OTHER

The online intervention, "Endre", a digital smoking cessation counsellor that communicates with the user primarily through interactive web-sessions. Intervention content is tailored based on user input and individual usage pattern. Up to 14 unique sessions is assigned to the users during the study period, one each day. If a user does not start a session by noon on the second day a reminder will be sendt.
