Nicodermal patch adherence and its correlates

Abstract

The patch adherence behavior of 101 smokers receiving 8 weeks of the nicodermal patch was examined while undergoing one of three levels of adjunctive psychosocial treatment. Additionally, regression analyses were undertaken to: (1) identify subject variables predictive of patch adherence and (2) to determine the predictive validity of patch treatment dropout, smoking and patch adherence during patch treatment to smoking 9 and 26 weeks post-treatment entry. Fifty-five percent of the patients wore the patch as prescribed for at least 50 of 56 treatment days. A multiple regression model including the Fagerström severity of dependence score, psychosocial treatment group, and the URICA commitment score predicted 18% of the variance in days of patch use. All treatment dropouts were found to be smoking at followup. Although both smoking and low patch compliance during treatment were significant predictors subjects of week 9 and 26 smoking for the remaining subjects, at the individual variable level of analysis, only smoking during treatment predicted week 9 and 26 outcomes in a two-variable predictor model.
