Abstract:

OBJECTIVE: Social support interventions may enhance access and use of evidence-based tobacco cessation treatments (EBCTs). We assessed the feasibility of a proactive social support intervention for Veterans who smoke. METHODS: We used national Veterans Health Administration (VHA) data to identify Veterans who smoke cigarettes in the United States. We mailed invitation letters to a random national sample, followed by telephone outreach. Veteran-support person dyads were randomly assigned to intervention or control conditions. Support persons in the intervention group additionally received a 1-call coaching session. Assessments were conducted at baseline, 1-month, and 4-months post-randomization. Data collection occurred from March 2021 - August 2022. RESULTS: A total of 27 dyads were randomized. Two-thirds of Veteran participants were women. Veteran follow-up survey response rates were 81.5 %. Intervention participants reported a higher rate of cessation medication use (57.1 % vs. 30.8 %), use of any EBCT (64.3 % vs. 38.5 %), and biochemically confirmed seven-day point-prevalence abstinence (14.3 % vs 7.7 %) than control participants. The proactive recruitment rate was 6 % for Veterans, 74 % for support persons, and a 93 % support person completion rate for the coaching call intervention. CONCLUSIONS: Recruitment methods were feasible, especially for women Veterans. A proactive social support intervention shows promise for increasing Veteran utilization of EBCTs.
