Group/Cohort Intervention/treatment
Crrent Male smokers

Male smokers met the inclusion criteria below will be invited to fill in the questionnaires set, part of them will be invited to attend a semi-structured interview(optional).

  1. be aged 18 or above,
  2. have a history of smoking at least one cigarette per day before their partners became pregnant,
  3. be involved with partners whose pregnancies could be confirmed,
  4. able to read Chinese and communicate in the Mandarin dialect.
Other: Questionnaires set
Participants will be asked to respond to the demographic information sheet, Smoking characteristics sheet, the Fagerstrom Test of Nicotine Dependence, the Transtheoretical Model (TTM) variables, Smoking Self-efficacy Questionnaire (SEQ-12), Family Adaptation, Partnership, Growth, Affection, and Resolve (Family APGAR), and a smoking hazard questionnaire.

Primary Outcome Measures :
  1. Quit intention of smoking [ Time Frame: Baseline ]
    The level of intention to quit of smoking among male smokers who planning to have a baby with their partners will be measured by b) The Transtheoretical Model (TTM) variables. The Stage of TTM will be assessed by asking the intention of quitting smoking in the past 6 months with the 6-items, which are Precontemplation, Contemplation, Preparation, Action, Maintenance, and Termination

Secondary Outcome Measures :
  1. Self-efficacy level [ Time Frame: Baseline ]
    Self-efficacy of participants against tobacco will be assessed by using by the SEQ-12. The SEQ-12 is categorized into two subscales, namely internal stimuli (6 items) and external stimuli (6 items), with total possible scores ranging from 6 to 30 for both internal stimuli and external stimuli. Higher scores of the SEQ-12 on both subscales indicate greater self-efficacy to refrain from smoking.

  2. Self-awareness of the hazard of smoking [ Time Frame: Baseline ]
    The self-awareness of the hazard of smoking among the participants will be measured by a self-designed smoking hazard questionnaire list. The smoking hazard questionnaire lists 14 hazard of smoking and SHS to the pregnant, fetus, health, income, social activity, and so on. Participants responded to each items using a -10 to 10 rating scale ranging from -10 (most negative influence) to 10 (most positive influence).

  3. Family support level [ Time Frame: Baseline ]
    The family support for smoking cessation will be assessed by using the Family APGAR. The Family APGAR is a 5-item measure of perceived family support [71]. Participants responded to each item using a 5-point rating scale ranging from 0 (never) to 4 (always). The standard scoring for the FAPGAR interprets high scores (7-10) as indicating a satisfactory support from family and low scores (0-3) indicating severe dysfunctionality support from the family members.

  4. Dependence of nicotine [ Time Frame: Baseline ]
    The level of nicotine dependence of the participants will be measured by the Fagerstrom Test of Nicotine Dependence (FTND) scale. The FTND is a standard instrument for assessing the intensity of physical addiction to nicotine.The test was designed to provide an ordinal measure of nicotine dependence related to cigarette smoking. It contains six items that evaluate the quantity of cigarette consumption, the compulsion to use, and dependence. In scoring the Fagerstrom Test for Nicotine Dependence, yes/no items are scored from 0 to 1 and multiple-choice items are scored from 0 to 3. The items are summed to yield a total score of 0-10. The higher the total Fagerstrom score, the more intense is the patient's physical dependence on nicotine.
