Abstract

The current paper explores the evolution and the comorbidity of anxiety and depression in the age group of 12 to 18-year-old adolescents. Based on the developmental psychopathology, it will look at the role of genetic vulnerability, personality (e.g., neuroticism), and environmental factors, e.g., parenting style, academic pressures, and social media influence play in these conditions. The study identifies the age variation in the manifestation of the symptoms such as somatic complaints in anxiety and cognitive distortion in depression. There is special emphasis on the sizeable role of peer relationships which may also serve as protective or risk factors. Anxiety and depression co-occurrence has high frequencies studied using Tripartite Model which focuses on common risk mechanisms. Low cost intervision, including Cognitive Behavioral Therapy, group therapy and emerging low-cost interventions are discussed with regards to their effectiveness in the treatment of both disorders concurrently. The results lend credence to the idea of coordinated and developmentally congruent assessment and intervention methods, and encourage future long-term studies that would assess long-term treatment behaviors.
