The psychiatric mental health nurse practitioner is interviewing a 21-year-old client with reports of anxiety symptoms. How long must symptoms be present for a diagnosis of generalized anxiety disorder (GAD)?

Choice A reason: Three months of symptoms is insufficient for a GAD diagnosis under DSM-5 criteria. While a patient may be highly distressed after 90 days, the diagnostic standard requires a longer duration to differentiate a chronic, generalized disorder from adjustment disorders or transient situational anxiety that may resolve once a specific stressor is removed. Choice B reason: One month is the typical timeframe required for diagnosing Panic Disorder or Post-Traumatic Stress Disorder (PTSD) regarding certain symptom clusters. However, generalized anxiety involves "excessive" worry about a variety of topics, and a one-month window is too brief to establish the pervasive and persistent nature required for a GAD diagnosis. Choice C reason: Two months of symptoms still does not satisfy the longitudinal requirement of the DSM-5. Establishing a pattern of "more days than not" over a two-month period might indicate a developing anxiety problem, but it does not meet the clinical threshold for a formal GAD diagnosis, which prioritizes chronic stability of the symptoms. Choice D reason: To meet the DSM-5 diagnostic criteria for Generalized Anxiety Disorder, excessive anxiety and worry must occur more days than not for at least 6 months. This worry must pertain to a number of events or activities, such as work or school performance, and must be difficult for the individual to control, accompanied by physical symptoms like restlessness or muscle tension.
