Abstract: Objective: To explore the association between complementary and integrative health (CIH) service use and completion of a Domiciliary Care for Homeless Veterans (DCHV) program. Methods: The sample included 227 veterans enrolled at one DCHV program between September 2021 and September 2023. Multivariable logistic regression analyses were conducted. Results: Veterans with 4-6 encounters and 7 or more encounters had 3.3 times and 4.8 times greater odds of program completion compared with veterans who did not have any CIH encounters, repectively. Conclusion: Study results indicated that increased use of CIH services was associated with an increased likelihood of DCVH program completion.
