Summary

This pilot trial aims to examine the feasibility, acceptability, and preliminary effectiveness of EMA-based peer counseling for youth smokers.

Detailed description

Most smokers begin smoking during adolescence and early adulthood, a crucial period to prevent initiation and continuation of smoking. However, many proven smoking cessation interventions for adult smokers were not found effective in youth smokers, which may be partly explained by the vast differences in the pattern of tobacco use and determinants of quitting between adult and youth smokers. This calls for more research on novel intervention models to help young smokers quit. The HKU Youth Quitline provides free smoking cessation support for smokers aged below 25 years since August 2005 in Hong Kong. The service provides multisession peer-led telephone counselling with an individualised quit plan devised for each young smoker according to their responses. Since the counselling model depends on the information retrospectively recalled by the smokers, it may be prone to recall and social desirability biases and fail to capture the variability of youth smoking patterns and momentary changes in personal (e.g., mood) and situational (e.g., peer smoking) antecedents of smoking episodes. Recent advances in mobile technologies have enabled the use of more advanced and robust data collection approaches like ecological momentary assessment (EMA), which may benefit the counselling model by providing more ecologically valid data than traditional surveys. Previous studies have demonstrated the feasibility of using EMA to collect data on psychosocial processes and smoking behaviours in adolescent smokers. Therefore, we propose to develop and test a mobile EMA-based counselling intervention for youth smokers by conducting a pilot RCT.

Conditions

• Smoking Cessation

Interventions

Type	Name	Description
BEHAVIORAL	EMA assessment	Subjects will be asked to complete 3 waves of ecological momentary assessment (EMA) about smoking cues and smoking consumption via mobile phone at the first, second and third month after baseline (total 6 weeks)
BEHAVIORAL	EMA-based cessation counselling	Subjects will receive tailored peer counselling based on the participants' EMA responses at 1-month and 3-month telephone follow-ups.
BEHAVIORAL	Usual peer counselling	Subjects will receive peer counselling through telephone during follow-ups (usual care), in which the counsellor will apply the 5As model and motivational interviewing techniques.
