Study Arms (2)

quit immediately (QI)

EXPERIMENTAL

Subjects in the QI group will receive a smoking cessation booklet plus a brief intervention using the AWARD model: (a) Ask about smoking history, (b) Warn about the high risk, (c) Advise to quit now, as quitting can greatly reduce risks, (d) Refer smokers to a smoking cessation clinic, and (e) Do it again: repeat the intervention during each telephone follow-up. The whole intervention will be limited to less than 1 min or slightly longer if necessary. For the subsequent telephone follow-ups at 1, 3, 6 and 12 months, the counsellor will congratulate to the subjects who successfully quit smoking, while deliver the same brief intervention as a booster for those who continue to smoke.

Behavioral: quit immediately (QI)

cut down to quit (CDTQ)

EXPERIMENTAL

Subjects in the CDTQ group will also receive the smoking cessation booklet plus a brief intervention using the AWARD model. Instead of asking them to quit immediately, they will be advised gradually cutting down on their cigarette consumption. Also, the subjects will be provided with an education card that contains reduction strategies and a suggested plan to reduce smoking. For the subsequent telephone follow-ups at 1, 3, 6 and 12 months, the nurse counsellor will repeat the warning message that one out of two smokers will be killed by smoking, and remind the subjects of their next reduction target. The counsellor will congratulate subjects who quit or reduce smoking on their success. When subjects fail to quit or reduce their cigarette consumption, the counsellor will reinforce the health hazards of continued smoking and the benefits of quitting, and encourage them to try again immediately or in the near future.

Behavioral: cut down to quit (CDTQ)
