Greater engagement in valued activities is associated with less barriers to quitting smoking among smokers with mobility impairments.

Background: Individuals with mobility impairments (MI; use equipment to ambulate) have a high prevalence of both smoking and depression. Behavioral activation (BA) purports that depressed mood is remediated through valued activity engagement and may facilitate smoking cessation in MI populations.
Objective: We examined cross-sectional associations between activity engagement and variables important for smoking cessation among a high-risk group of smokers (people with MIs) and also describe a smoking cessation intervention based on BA, given the lack of studies on smokers with MIs.
Methods: This study used data from a smoking cessation trial enrolling smokers with MIs (n = 263). We assessed valued activities, activity type, activity restriction due to MI, and replacement of restricted activities. Motivation and confidence to quit smoking, number of cigarettes per day, and mood were also assessed. Analysis was performed with generalized linear (or logistic) regression models adjusted for age and physical functioning using aggregated data at baseline.
Results: Greater number and frequency of valued activities was associated with less smoking, depression, negative affect, and stress and higher positive affect and self-efficacy to quit. Activity restriction was associated with greater odds of major depression, and activity replacement with lower odds of major depression, lower stress, and higher positive affect and self-efficacy. Strength of associations varied by activity type.
Conclusions: Consistent with our theoretical model, BA activity constructs were associated with several mediators of smoking outcomes in the expected directions. Smokers engaging in valued activities have more favorable profiles for smoking cessation and mood management.
