Condition or disease Intervention/treatment Phase
Smoking Cessation Behavioral: Mobile Phone-Based Intervention Not Applicable

Detailed Description:


Smoking remains a major public health problem and an important cause of morbidity and mortality worldwide. Although the effectiveness of behavior support and medical treatment, many of those who quit smoking subsequently relapse to smoke.


The primary aim of this study will be to determine the effectiveness of the mobile phone-based intervention to prevent relapse among recent smoking quitters. Also, the study aims to identify the different factors associated with relapse among recent quitters during the first 6 months of quitting.

Design and Methods:

A parallel two-armed Randomized Controlled Trial (RCT) to assess the effectiveness of a mobile phone-based intervention for smoking cessation on achieving long term abstinence, will be conducted among volunteers. Participants will be recruited from those attended smoking cessation program in Southern Alrawdha clinic, Southern Abo Arish clinic, Sabia clinic and Aldhabia clinic.

Primary outcome:

The difference in relapsing rate among recent quitters, which may subsequently contribute in to a reduction in smoking rates.

Trail Implications for public Health:

The result of this study will provide evidence for effectiveness of the mobile phone-based intervention versus standard treatment to reduce smoking relapse rate. If proven, it will be a cost-saving intervention by reducing repeat use of the smoking cessation clinic services and by reducing use of healthcare services for smoking-related illness.

Arm Intervention/treatment
Experimental: Intervention group
Intervention group will be enrolled to the intervention program proposed to be (pharmacotherapy + counseling+ motivator phone messages).

The program will be carried out using the word "Mettle", it will help ex-smokers stay off cigarettes through advices generated to promote the health from religious concepts and culture perspectives .

No Intervention: Control group
Control group will receive the standard treatment of the Ministry of the Health program (pharmacotherapy + counseling) only.

Primary Outcome Measures :

    Relapse rates at the end of the 3rd and 6th month of follow-up in the intervention and control groups.

Secondary Outcome Measures :
  1. Secondary outcomes included: (1) timing till self-reported relapse. (2) causes of relapse. [ Time Frame: 6 months following scheduled quit date ]
    Participants will be asked core smoking status questions, including whether they have smoked any cigarettes or used other tobacco products, even a puff, in the last 30 days, 7-day point prevalence abstinence, the exact day of each smoking relapse episode and the cause of relapse.
