Wang N, et al. - Researchers investigated the prevalence of mental health service use among US adults. Further, they determined how mental health service use is associated with health insurance coverage, mental health problems and drug use, and detect health disparities. Out of 37,424 adult respondents from the 2013 National Survey on Drug Use and Health, 5,434 adults receiving mental health service were included in this cross-sectional study. The overall prevalence of mental health services use of 14.7% was reported. Mental health service use was noted to be positively correlated with being female, aging, having a major depressive episode, serious psychological distress, and illicit drug or alcohol abuse/dependence; whereas it was negatively correlated with being African American, Asian or Hispanic ethnicity, married, and having any form of insurance. They noted a positive correlation of Medicaid/CHIP, CHAMPUS, and other insurance with mental health service use when stratified analysis by insurance types was done.
