RESUMEN
The use of e-cigarettes ("vaping") by young adults has increased substantially in the past decade. Although health risks of long-term e-cigarette use remain unknown, there is evidence of acute physiological harms. Most young adults who vape report intent to quit, but little is known about effective interventions. This protocol paper reports on the development and design of a pilot trial of a vaping intervention for young military Veterans. Young adult Veterans accessing VA healthcare (n = 20) who vape daily and have been referred for cessation services will be enrolled. To maximize accessibility the intervention will be delivered virtually; participants will be randomized to receive behavioral counseling by telephone or by video telehealth. The intervention was adapted from an existing program targeting young adult cigarette smokers and will include 6 individual counseling sessions delivered over 8 weeks. Assessment visits will occur at baseline, at end-of-treatment, and 4 weeks later. Analyses will evaluate feasibility and acceptability of the intervention overall, and will compare telephone and video telehealth modalities. Longitudinal regression will be used to evaluate changes in vaping behavior and in nicotine dependence over time. This study will provide assessment of a novel intervention adapted for Veterans who vape nicotine. The comparison of two modalities of virtual intervention delivery will increase knowledge and the potential to disseminate across VA and other healthcare systems. Findings from this pilot trial will inform the design of future, larger studies of vaping cessation interventions for younger Veterans.
