“…Five DTC client sociodemographic variables of particular interest for the current study include age, race and ethnicity, gender, education, and employment: age Most studies show a positive correlation between older age and successful DTC completion among adults, with younger DTC clients more likely to drop out (gallagher, Ivory, Carlton, & Miller, 2014;Jewell, Rose, Bush, & Bartz, 2016;Shannon, Jackson, Newell, Perkins, & Neal, 2015).
