Summary

This randomized controlled trial evaluated the feasibility and potential efficacy of 1) e-cigarette switching (EC) or 2) e-cigarette switching + financial incentives for combustible cigarette cessation (EC+FI)

Detailed description

The current study examined the feasibility of e-cigarette switching and financial incentives contingent on combustible cigarette abstinence to promote combustible cigarette cessation among urban day shelter guests (N=60). A total of 60 adults who accessed the Homeless Alliance day shelter in Oklahoma City, OK were randomly assigned to 1 of 2 groups and followed weekly from 1 week prior to a scheduled EC switch date through 4 weeks post-switch date, with a final 8-week post-switch follow-up. The intervention groups were: 1) e-cigarette switching (EC) or 2) EC switching + small financial incentives for carbon monoxide (CO) verified combustible cigarette abstinence (FI + EC). The primary outcomes were self-reported combustible cigarette abstinence over the previous 7 days with carbon monoxide (CO)-verification at 4- and 8- weeks follow-up. Secondary outcomes included changes in CO from baseline, days of combustible cigarette smoking, and continued e-cigarette use. Other feasibility outcomes included study retention and perceptions of the intervention.
