Introduction Depression is a psychological disorder that afflicts people in different stages of their development. This paper selects and reviews five articles on depression with a particular focus on teenage misery. It then creates a case study for a client who is experiencing the chosen issue or condition. The last section discusses a possible positive psychology-based treatment plan for the client. Summary of the Articles Bennet (2014) provides important statistical findings that help to portray the significance of depression disorder. For example, the scholar informs that about 6.7% (14.8 million) of all United States’ adults suffer from Major Depressive Disorder (MDD). Arguing from a survey conducted in 2012 by Harris Interactive on behalf of the American Psychological Association, the author reveals that millennials (18-33 years) are more likely to suffer from depression when compared to other age groups. The survey indicated that 19% of millennials were likely to be informed by their doctors that they had depression or an anxiety disorder compared to 14% for cases involving 34-47 years, 12% for 48-66 years, and 11% for 67 years and above years (Bennet, 2014). The author further mentions how social work scholars contend that the majority of the young people who are put under their care have psychological challenges associated with depression. Using data derived from Psychology Today, Gallerani, Garber, and Martin (2010) argue that high school and college young adults have 5-8 times the possibility of suffering from depression compared to teenagers who lived 5 to 6 decades ago. This finding suggests an increased rate of depression among adolescents as years progress. Although Gallerani et al. (2010) assert that the US has been experiencing an increasing level of teenage depression, the article fails to provide comparative data, which is necessary for determining the trend or changes over the last decade. Young and Dietrich (2015) researched to examine mechanisms that predict depressive and anxiety symptoms to identify risk factors that could be modified to promote health and interventions. The research drew its sample from 11-15-year-old teenagers. After making adjustments for various baseline values, rising anxiety levels increased worry, and rumination predicted depressive symptoms. Young and Dietrich (2015) recommended the creation of programs addressing these factors to help in managing depression among teenagers. A discussion of depression is incomplete without a consideration of its ontology and epistemology. However, Huang and Fang’s (2015) article argues that such a possibility is slim considering that the manual of psychological mayhem provides just only the criteria for a major depressive episode. The article emphasizes that the manual fails to define depression in its ontological terms. Rather, the criterion is based on how one can recognize that he or she suffers from depression. Hence, the Diagnostics and Statistical Manual of Mental Disorders (DSM-1V) only describes depression but does not offer reasons for the combination of causes or even the reasons for the collective symptoms that characterize depressive episodes (Huang & Fang, 2015).
