Smoking Cessation Intervention Clinical Trial
Official title:
Building Capacity and Promoting Smoking Cessation in the Community Via Quit to Win Contest 2014: a Randomized Controlled Trial
Although smoking prevalence is decreasing in Hong Kong, there are still 645,000 daily
smokers 10.7% ( Thematic Household Survey 2012) and half will be killed by smoking (Lam
,2012) which accounts for over 7,000 deaths per year (Lam, Ho, Hedley, Mak, & Peto, 2001).
Smoking also accounts for a large amount of medical cost, long-term care and productivity
loss of US$688 million (0.6% Hong Kong GDP) (McGhee et al., 2006) (Census & Statistics
Department (Hong Kong Special Administrative Region government), 2001). Smoking is a highly
addictive behavior and it is difficult for smokers with strong nicotine dependence to quit
without assistance. On the other hand, reaching and helping the many smokers who have no
intention to quit is a challenge, because they are unlikely to seek professional help from
smoking cessation services. The Quit and Win programme provides an opportunity to reach and
encourage a large group of smokers to make quit attempt and maintain abstinence. The Quit
and Win model posits that smokers participating in the contest will have higher motivation
to quit with incentives and better social support (Cahill & Petera, 2011). Studies have
found that such quitting contests or incentive programs appeared to reach a large number of
smokers and demonstrated a significantly higher quit rate for the quit and win group than
for the control group (Cahill & Rafael, 2008).
The Quit to Win Contest in 2014 and the study's interventions using cut down to quit
approach are theoretically based on the Health Action Process Approach ( HAPA) for the
intervention group (Schwarzer, 2008). The HAPA suggests that one's intention of behavior
change can be fostered by knowing that the new behavior has positive outcomes as opposed to
the negative outcomes that accompany the current behavior; and planning (action planning and
coping planning) which serves as an operative mediator between intentions and behavior.
Using gradual cut down approach on smoking cessation will probably increase smoker's
self-efficacy on smoking cessation as the process could be achieved at the smoker's own
perceived pace without placing too much pressure on themselves but with greater control of
self in the cessation process. This was supported by the evidence that smoking reduction
approach led to a greater self-efficacy to resist smoking and increased subsequent quitting
(Broms, Korhonen, & Kaprio, 2008). Most importantly, reducing cigarette consumption will
lower the nicotine dependence which is associated with later abstinence (Hughes et al.,
2004). On the other hand, quitting immediately will have a less sense of control and may be
subjected to relapse thus lower the self-efficacy on quitting.
Therefore, the present study will examine (1) effectiveness of the cut down to quit (CDTQ)
and quit immediately (QI) approaches; (2) explore the use of Community-Based Participatory
Research (CBPR) model to build capacity and to engage community partners in taking on this
important public health issue for sustainability in the community. In addition, process
evaluation will be conducted to assess the effectiveness of the recruitment activity and how
it is linked with the overall program outcomes.
