Anger Management and Stress Control for Smoking Cessation
This inventory is based on the Ways of Coping Styles questionnaire designed by Folkman and Lazarus. Sahin and Durak worked on the Turkish version of this scale and developed the Styles of Coping with Stress Inventory. This consists of 30 self-reported items on a 4-point Likert scale. The questionnaire has 5 subscales indicating different approaches to coping with stress: self-confident approach (7 items), optimistic (5 items), hopeless (8 items), seeking social support (4 items), and submitted (6 items). Cronbach α values for the subscales were calculated as 0.92, 0.86, 0.88, 0.94, and 0.84. The overall Cronbach α value for Styles of Coping with Stress Inventory is 0.90. A higher scores on any subscale indicates that the subject uses that approach to cope with stress. We used the self-confident and hopeless subscales in our study. The individual can score from 0 to 21 on the SCS and from 0 to 24 on the HS. Subjects with higher scores on the SCS are regarded as using effective (problem-based) stress coping skills. However, subjects with higher scores on the HS are regarded as using ineffective (emotion-based) coping skills.
The results of the items (pretest, post-test, first follow-up and second follow-up of TAS, SCS, and HS) were regarded as independent variables. The relations between demographic, smoking features, and results of the items were investigated using the χ test, Pearson correlation analysis, the independent samples t test, and 2-way repeated measures analysis of variance. Two proportions tests were used to analyze the difference between cessation success rates between the treatment groups. Independent factors affecting smoking cessation were investigated using logistic regression analyses. Minitab version 10 (Minitab, Inc.; available from: http://www.minitab.com/en-us/downloads/) was used for power analyses and the 2 proportions test. All the remaining statistical analyses were performed on SPSS version 13.0 (SPSS, Inc., Chicago, IL). P < .05 was considered statistically significant.
