Background: Recently, the use of communication technologies and social media applications has
become increasingly widespread to strengthen efforts for smoking cessation. The purpose of
this study is; to assess the effect on success rate of the WhatsApp application which is
embedded in the smoking cessation policlinic service delivery.
Materials and Methods: A randomized controlled intervention study was conducted with 132
volunteers who were followed up at the EUTF Smoking Cessation Policlinic between March-July
2017. The intervention content based on transtheoretic model was prepared and 60 WhatsApp
messages were delivered to participants for 3 months of follow up. For data collection,
initial interview form and follow up form consisting sociodemographic characteristics,
smoking status, medical condition and treatment, were used. The success rate at first and
third months were assessed by the point-prevalence regarding the previous week.
Intention-to-treat analysis was used. For secondary outcomes; number of follow-ups, change in
weight and continuity of medication were evaluated.
Findings: Success rate in the first month was 65.9% for intervention group and 40.9% in the
control group; for the third month it was 50.0% in the intervention group and 30.7% in the
control group. Being in the intervention group increased the success rate by 3,50 (1,30-9,44)
times in the first month and 2,50 (1,08-6,40) times in the third month. The intervention was
the only parameter effective in the two follow-up periods; the difference in success rate
caused by gender, marital status and work-related social class has been eliminated after
adjustment for the intervention.

Primary | Quitting success rates at the end of the 1st, 3rd and 6th month | Quitting success rates at the end of the 1st, 3rd and 6th month of follow-up in the intervention and control groups. Quitting success rate at 1st month was calculated with point prevalence. History of cessation was based on self report and those who declared not smoked even a single puff on a cigarette at all in the past two weeks were considered as "successful" in the quitting attempt (19). The success rate at 3rd month was calculated with point prevalence. In this point, not smoking at all in total in the past ten weeks was considered "successful" in the quitting attempt. The success rate at 6th month was calculated with point prevalence. In this point, not smoking at all in total in the past 24 weeks was considered "successful" in the quitting attempt. A decrease in success rates at six months is expected in comparison with 3 months as the intervention lasts for 3 months. |

Secondary | The total number of follow-ups | The total number of follow-ups in the 1st, 3rd month. Contacts were divided into two categories: face-to face contacts and telephone calls. The total number of routine follow-ups was classified as adequate when 3 or more in the 1st month and a total of 4 follow-ups was considered as adequate at 3rd month. At 1st month, at least one of these follow-ups was required to be face-to-face for adequacy. | 3 months | |
Secondary | The continuity to drug, | The continuity to drug/NRT therapy was categorized as using the prescribed drug for <1 month or =1 month. | 3 months | |
Secondary | Self reported difference in weight in kilograms since the first contact | Any increase in weight (kg) was categorized as; has weight gain, no weight gain. | 3 months |
