Experiential avoidance (EA) appears to be a predictor of major depressive disorder (MDD) and generalized anxiety disorder (GAD) symptomatology in older adolescents, according to results published in the Journal of Clinical Psychiatry.

The longitudinal study (NCT02147184​) gathered data from adolescents ages 15 to 20 years (N=183) who were followed for 2 years using a comprehensive assessment battery. Using weekly evaluation of EA, depressive, and anxiety symptoms, investigators identified 4 combined MDD/GAD trajectory groups: persistent (n=81), high-decreasing (n=44), normal-increasing (n=37), and minimal (n=21).

Adolescents in the persistent group had higher EA than other groups (P ≤.001), with greater EA stability compared with adolescents in the high-decreasing group (P =.008). Experiential avoidance predicted both depressive and anxiety symptoms (P ≤.005); however, these symptoms did not predict EA (P ≥.188).

“The findings of the current study suggest that an intervention targeting EA in adolescents may lead to valuable outcomes,” investigators wrote. As a possible intervention, investigators noted that acceptance and commitment therapy is an effective therapy for EA and an empirically supported treatment for MDD and anxiety.
