This aligns with the DSM-5-TR criteria which emphasize the role of stressors in the development of adjustment disorders. Emotional and Behavioral Symptoms: Pete exhibits signs of emotional distress, including feelings of worthlessness and life feeling "pointless." His diminishing academic performance and increased distance from family also reflect behavioral changes typical of this disorder. Timing: The timeline of the stressor coincides with the onset of his symptoms, fitting within the three-month window outlined in the criteria for Adjustment Disorder. Functional Impairment: Pete's academic decline and reported emotional withdrawal indicate significant impairment, which is a key factor in diagnosing Adjustment Disorder. Need Assignment Help?
