Abstract:Chronic obstructive pulmonary disease (COPD) is characterized by a progressing deterioration of lung functioning, with tobacco smoking as major risk-factor. Since smokers with COPD experience complete smoking cessation as too difficult to achieve, the REDUQ study employed a behavioral and pharmacological intervention that was tailored to smoking reduction in order to increase the motivation for complete smoking cessation in COPD patients that were not ready to quit. Based on the theoretical framework of the I-change model and the health-belief model of behavior change, the aim of the present study was to examine changes in cognitive determinants (attitude and self-efficacy) of smoking cessation in regard to changes in the smoking behavior within and between four smokers with COPD with varying impairment in health-related quality of life (HRQL) that participated in an intensive smoking reduction intervention. Therefore, a single-case experimental design (SCED) in combination with a multiple baseline design was implemented, with non-concurrent baseline phases and follow-up phases of 5, 6, 7, or 8 weeks and a concurrent treatment phase of 13 weeks. The cognitive determinants and the smoking behavior were weekly measured by the use of a telephone-interview. The results indicated that the smoking reduction intervention was equally effective in smokers with COPD who reported varying severity in impairment in HRQL. Furthermore, this study supported the importance of self-efficacy as motivational determinant of subsequent changes in smoking behavior among COPD patients and suggests that smoking reduction interventions should incorporate frequent monitoring and enhancement of self-efficacy as a consistent part of the treatment.
