About this trial
The goal of this study is to evaluate the efficacy of a culture specific text-messaging based shisha smoking cessation intervention for young adults in Hong Kong. Participants in the intervention group will receive smartphone text messaging-based intervention and support that contained personalised messages with both text and visual elements over 6 weeks under a manualised programme. Participants in the control group will only receive a leaflet about the health risks of shisha smoking (the exact identical contents received by the participants in the intervention group at a session).
All participants will complete a self-administered questionnaire at baseline, 6th- and 12th-week on their self-reported shisha abstinences, knowledge on risk, readiness to quit and attitudes on shisha smoking

Trial outcomes
Primary outcomes
1
shisha abstinences
To compare the self-reported shisha abstinences between intervention and control group to evaluate the efficacy of the culture specific text-messaging based shisha smoking cessation intervention. Shisha abstinence is determined by self-reported last use 1) in the past 7 days using the Timeline Followback Method for active use, 2) in the past 30 days to determine current use, and 3) in the past 90 days to determine early remission in accordance with the criteria from the Diagnostic and Statistical Manual for Mental Disorders, 5th Edition.
Time frame
From enrollment, 6-week (after treatment) and 12-week follow-upSecondary outcomes

Level of dependency
To compare the level of dependency between participants in intervention and control group during the study by using the diagnostic criteria from the Diagnostic and Statistical Manual of Mental Disorders, fifth version on Other Substance Use Disorder under Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, fifth version. Participants will be classified as having no (0-1), mild (2-3), moderate (4-5), or severe (6-11) substance (shisha) use disorder. The minimum score ranged from 0 to 11.
Time frame
From enrolment, 6-week (after treatment) and 12-week follow-up2
Knowledge on risk
To compare the knowledge on risk between participants in intervention and control group during the study period by using a self-designed 10-item multiple choice questions (True/ False/ Do not know). Each correct answer will have 1 score, the score ranged from 0 to 10, with higher score indicates better knowledge.
Time frame
From enrolment, 6-week (after treatment) and 12-week follow-up3
Readiness to quit
To compare the readiness to quit between participants in intervention and control group during the study period using The Contemplation ladder. This measurement is a valid tool consists of 11 rungs ranging from 0 = 'no thought about quitting' to 10 = 'have already quitted', representing 5 stages of change in readiness for cigarette smoking and substance use control.
Time frame
From enrolment, 6-week (after treatment) and 12-week follow-up4
Attitudes on shisha smoking
To compare the attitudes towards shisha smoking between participants in intervention or control group during the study period by self-designed a 14-item, 5-point Liker scale (ranging from 1 = Strongly disagree to 5 = Strongly agree), the score ranged from 14 to 70, higher score represents more positive attitude towards shisha smoking.
