Brief Summary

To conduct a pilot study to determine the feasibility, potential efficacy and effect size of a personalized general health promotion approach using Information Communication Technology (WhatsApp or WeChat) to deliver a brief Motivational interviewing (MI) in promoting smoking cessation among smokers having follow-up in a Special Out-Patient Clinic (SOPC). In addition, this pilot study aims to assess the potential facilitators and barriers of future implementation of using such approach for smokers with chronic diseases. Based on the findings of the pilot study, a large RCT will be conducted to evaluate the effectiveness and costs of a personalized general health promotion approach in promoting smoking cessation for smokers with chronic diseases in Hong Kong in the future.

Conditions

Smoking Cessation

Outcome Measures

Primary Outcomes (1)

• Biochemically validated smoking abstinence at 12 months

  The biochemically validated 7-day point prevalence of abstinence will be confirmed by saliva cotinine level \< 115 ng/ml in parallel test and a carbon monoxide level in expired air \< 9 parts per million (p.p.m.).

  12-month follow-up

Secondary Outcomes (3)

• Self-reported 7-day point prevalence of smoking abstinence at 6 and 12 months

  6- and 12-month follow-up

• Self-reported reduction of ≥ 50% in cigarette consumption at 6 and 12 months

  6- and 12-month follow-up

• Any behavioural change reported by the subjects at 1, 3, 6 and 12 months

  1-, 3-, 6- and 12-month follow-ups

Study Arms (2)

Intervention group

EXPERIMENTAL

The trained RA will deliver brief MI to each subject individually via WeChat or WhatsApp in the smart phones throughout the study period. The brief MI messages will be delivered more intensively as preferred by the subject (usually not less than once per 2-3 days and no more than 2 times per day) for the first 6 months. The frequency of delivering message through WeChat or WhatsApp will be interactive, depended on subjects' actions and responses. Start from 6 months, minimal messages by merely following the subjects' progress and responding to their questions to maintain contact will be provided to subjects till one-year follow-up. The readiness of quitting smoking will be assessed at 3-month follow-up. For those who are willing to take further actions to promote their health, i.e. with an intention to quit smoking, health advice on smoking will be given with more emphasis on the health benefits of quitting. The whole intervention will be given through WeChat/WhatsApp.

Behavioral: Brief Motivational Interviewing (i-BMI)

Control group

OTHER

Subjects in the control group will not receive brief MI and follow-up booster intervention. Subjects will be informed that they will receive follow-up telephone call at 1, 3, 6 and 12 months

Behavioral: Control

Interventions

Brief Motivational Interviewing (i-BMI) BEHAVIORAL

The trained RA will ask the subjects about the priority of engaging in any desirable health-related lifestyle practice as identified in the completed baseline questionnaires and to state a targeted goal that they perceive as the easiest to achieve. Each subject will then receive an individual face-to-face brief MI (about 5 mins) with generic health advice on selected health-related lifestyle practice. They will then be informed to receive an individual brief MI intervention to assist behavioural changes or achieve goals as desired or chosen by them via WeChat or WhatsApp in smart phones throughout the study period. They will be given a self-help smoking cessation booklet with Hotline number. The RA will then deliver brief MI to each subject individually via WeChat or WhatsApp in smart phones throughout the study period. Readiness of quitting smoking will be assessed at 3-month follow-up. Upon request by subjects, we shall provide them with more comprehensive information on quitting.

Intervention group

Control BEHAVIORAL

Similar to the intervention group, the trained RA will first ask the subjects about the priority of engaging in any desirable health-related lifestyle practice and to state a targeted goal in which they perceive as the easiest to achieve after completing the baseline questionnaires. In addition, the subjects will be given a self-help smoking cessation booklet with Hotline (Tel.: 1833183). However, subjects in the control group will not receive brief MI and follow-up booster intervention. Subjects will be informed that they will receive follow-up telephone call at 1, 3, 6 and 12 months.
