Table 1 Details of behavior change intervention package in two arms (brief intervention arm and intensive intervention arm) of the study

Brief and intensive

(Individual counseling)

This will involve face-to-face appointments of patient with researcher aimed to motivate, guide, and psychologically assist tobacco users in quitting. This patient-centered approach enhances an individual’s motivation for change through self-examination and identification of ambivalence to change and the subsequent resolution leading to sustained positive behavior change. It will include asking patients about their tobacco use status, and discuss the options that exist to support a quit attempt

10–20 min/once during first contact/researcher

Both minimal (< 20 min in 1 visit) and intensive (≥ 20 min plus > 1 follow-up visit) physician-advice interventions effectively increase the proportion of adults who successfully quit tobacco and remain abstinent for ≥ 6 months [8]. There is a dose–response relationship between the intensity of counseling and cessation rates (i.e., more or longer sessions improve cessation rates) [38]

(Motivational videos)

Videos based on real life stories of patients with tobacco use history will educate and sensitize patients and care givers on harmful effects of tobacco and motivate patients to quit

3–5 min/once during first contact/researcher

Technology including mobile phones, the internet, and social media platforms, can increase access to care by extending the work of counselors and overcoming the geographical barriers. These supports can increase the likelihood of adults quitting compared with no intervention and can be a cost-effective adjunct to other treatments [39]

(Patient information leaflet (PIL))

Patient information leaflet will be based on specific characteristics or concerns of tobacco users and include written material aiming to educate patients about the disease, ill effects of using tobacco on health, benefits of quitting and how to resist cravings and avoid relapse

Once at first contact/researcher

Providing self-help materials (primarily print-based) tailored to the individual patient (that is, beyond a brochure that simply describes the health effects of tobacco use and benefits of cessation) is effective in improving tobacco abstinence [40]

Intensive

(Telephone counseling)

Counseling through regular telephone follow-up will provide support and encouragement to individuals who uses tobacco and want to quit or individuals who have recently quit

05–15 min/five times at < 1, 4, 6, 9, and 12 weeks in 3 months after enrolment/researcher

Telephone-based access to counseling and smoking cessation resources increases cessation rates. The majority of helplines provide access to individual counseling; the greatest amount of counselor contact, the greater the likelihood of successful cessation [41]

(Text messages using SMS)

Messages will include short text based on the current stage of behavior as per trans-theoretical model for their motivation and support regarding tobacco cessation and maintaining quit status

Bi-weekly for 3 months/researcher

Technology, including mobile phones, the internet, and social media platforms, has the power to increase access to care by extending the work of counselors and overcoming geographical barriers. These supports can increase the likelihood of adults quitting compared with no intervention and can be a cost-effective adjunct to other treatments [39]
