Predictors of treatment utilization and unmet treatment need among individuals with posttraumatic stress disorder from a national sample

Objective: Posttraumatic stress disorder (PTSD) is a chronic psychiatric condition associated with significant disability that often remains untreated. Sociodemographic and family-level factors may serve as predictors of unmet treatment need, identifying groups that would most benefit from policies aimed at increasing access to the mental health care system.

Method: Data from the nationally representative Collaborative Psychiatric Epidemiologic Surveys were used to identify predictors of mental health treatment utilization, both with a mental health specialist and with a general health practitioner, and self-reported unmet treatment need among individuals who endorsed past-year PTSD. We defined unmet treatment need as self-reporting a mental health problem and not accessing mental health care in the general or specialty mental health care system.

Results: Among 600 participants, predictors of unmet treatment need included being non-Latino black [odds ratio (OR) 2.11, 95% confidence interval (CI) 1.25-3.54], having a high school education versus some college (OR 2.45, 95% CI 1.34-4.48), and being employed or unemployed versus not being in the workforce (OR 1.74, 95% CI 1.00-3.02 and OR 4.95, 95% CI 1.60-15.34, respectively). Recursive partitioning identified younger age and being married as predictors of low treatment utilization.

Conclusions: Future research should elucidate barriers to accessing treatment among those with PTSD in these underserved groups.
