Prior research has demonstrated that a variety of demographic, socioeconomic, and environmental factors can influence the prevalence and severity of mental distress and whether an individual is likely to receive treatment. Behavioral health research has been limited to self-reported survey data, but advances in technology have provided increased opportunities to continuously capture and store data, and to learn about the help-seeking habits of its contributors. In response to the growing prevalence of technologically mediated crisis counseling services, this county-level ecological study evaluated whether these same disparities exist for help-seeking via Crisis Text Line, a free, ubiquitous, technology-based crisis counseling service. Because most suicide attempts are impulsive acts, crisis hotlines are often the only resource available to suicidal or at-risk individuals. It is critical that researchers and practitioners are aware of any population-level disparities limiting the use of these invaluable resources. To date, this is the first study to examine text-based help-seeking behavior among adolescents at a national scale. Results identify several factors associated with increased or reduced help-seeking behavior among adolescents in the U.S. Increased v rates of CTL usage occur in counties with higher mean household incomes, higher divorce rates, and lower residential stability. Rurality was the strongest predictor for low rates of help-seeking, and this finding is particularly concerning in light of elevated rates of suicide among rural counties. Low rates of help-seeking compound ongoing rural-urban disparities in traditional mental health services, and this finding suggests that increased suicide risk in rural areas cannot be explained by mental health professional shortages alone. Rural communities, particularly those with low support-seeking behavior and comparatively high suicide rates, should be the target of future research and outreach.vi
