- Intention to quit smoking [ Time Frame: up to 3 weeks ]Intention to quit smoking will be assessed by measuring the strength of the individual's intention with a mean score being calculated from the 3 questions asked. This will generate a score between 1 and 7 with a higher score indicating a higher intention to quit smoking. This measure has been used and reviewed in previous research (Francis et al, 2004).
- Stage of Change - smoking cessation [ Time Frame: baseline and 3 weeks ]Secondly, the Stage of Change (SOC) of intention will be measured, with higher scores indicating a greater intention to quit smoking. The corresponding scores will identify the SOC (1 =pre-contemplation, 2 = contemplation, 3 = preparation, 4 = action). This measure has been adapted from a previous study which investigated stages of change in relation to smoking cessation (Fathelrahman et al. 2009).
- Nicotine Dependence [ Time Frame: Baseline and 3 weeks ]Nicotine dependency will be measured using the standardised Fagerstrom Test for Nicotine Dependence (FTNP: Heatherton, Kozlowski, Frecker, & Fagerstrom, 1991)
- Outcome expectancy beliefs [ Time Frame: Baseline and 3 weeks ]Expectancy beliefs will be measured using a 10-item questionnaire which has been adapted from the Health Action Process Approach (HAPA) assessment tools (Schwarzer, 2007) by making the questions relevant to the specific patient group. The questionnaire is comprised of two sub-scales: positive outcome expectancies (items 1, 3, 4, 6, 9) and negative outcome expectancies (items 2, 5, 7, 8, 10). Each subscale sum scores will range from 5-20.
- Self efficacy [ Time Frame: Baseline and 3 weeks ]Self-efficacy to quit smoking will be measured using a 10-item scale which has been previously used in a study investigating self-efficacy influences on the effects of framing in smoking cessation (Riet, Ruiter, Werrij, & de Vries, 2008). Sum scores will range from 10 to 70 with higher scores indicating greater self-efficacy to quit smoking.
- Risk Perception [ Time Frame: baseline and 3 weeks ]Risk perception of smoking will be measured using a 5-item questionnaire. The items are similar to that used in a previous study (Clarke and Aish, 2002), however the questions have been adapted to increase the relevance for vascular arterial patients. Sum scores will range from 5-35 with higher scores indicating a greater risk perception in regards to smoking.
- Health locus of control [ Time Frame: baseline and 3 weeks ]Health locus of control will be measured using the Multidimensional Health Locus of Control Scale - Form C (MHLC; Wallston, Stein & Smith, 1994).
