Assessing Multiple Features Of Partner Support For Smoking Cessation In Dual-Smoker Couples

The purpose of this study was to evaluate a new scale to measure multiple aspects of partner support for quitting smoking relevant to dual-smoker couples, called the Partner Support for Quitting Scale. The best model fit (N = 238 individuals in 119 couples) considers the frequency of, confidence in, and perceived usefulness of partner support behaviors. Path analysis revealed that the Partner Support for Quitting Scale factors were uniquely predicted by relationship commitment and nicotine dependence and, in turn, predicted self-efficacy for smoking cessation and desire to quit. Preliminary support was found for the Partner Support for Quitting Scales' value as an assessment tool for measuring partner support for smoking cessation among dual-smoker couples.
