Adjustment Disorder versus Anxiety Disorder
Adjustment disorder is the development of emotional symptoms in response to an identifiable stressor occurring within 3 months of the onset of the stressor. The distress from an adjustment disorder is out of proportion to the severity and intensity of the stressor. The adjustment disorder can have specifiers such as “with depressed mood,” “with anxiety,” and “with mixed anxiety and depressed mood,” “with disturbance of conduct,” and “with mixed disturbance of emotions and conduct.” Adjustment disorders are classified as a “Trauma and Stressor-related disorder” in the DSM (American Psychiatric Association [APA], 2013) and resolve within 3 months of removing the stressor. Treatment is usually made up of brief psychotherapy (Gabbard, 2014).
Generalized Anxiety Disorder (GAD) is not born out of one identified stressor (though stressors can worsen signs and symptoms) but is excessive anxiety and worry about a number of situations and events and require 3 or more of the following symptoms: restlessness/feeling “keyed up”, easily fatigued, difficulty concentrating, irritability and muscle tension, and sleep disturbances. The anxiety symptoms have been going on for at least 6 months and is causing clinically significant distress in functioning (APA, 2013).
Adjustment disorder can be seen as a disorder of exclusion; if symptoms do not meet criteria for another psychiatric disorder, and there is a an identified precipitant of symptoms occurring within 3 months, adjustment disorder may be the most logical diagnosis. Adjustment disorder does not have a “checklist” of symptoms to make an objective determination of distress or dysfunction (Gabbard, 2014).
When I worked on the psychiatric unit in the Navy, we saw a lot of young sailors with adjustment disorder. Entering the military was enough of a stressor that they were displaying some conduct or emotional issues that prevented them from doing their job well. Many times, they wanted a service discharge but more often our psychiatrists returned them to work with therapy and medication. If they were admitted to the hospital 3 times within a year, they would be administratively discharged.
Diagnostic Criteria for OCD
Obsessive-Compulsive Disorder (OCD) is characterized by recurrent intrusive thoughts, images, or urges (obsessions) that typically cause intense anxiety; to alleviate anxiety and function in the world, clients with OCD must perform repetitive mental or behavioral actions (compulsions) related to their obsession according to rigidly defined rules.OCD typically starts in childhood or adolescence, persists throughout a person’s life, and can produce substantial impairment in functioning (Sadock et al., 2017). Among adults in the United States, prevalence rates are 2.3 percent, with females affected slightly more than males in adulthood, while males have higher rates that begin in childhood (Ruscio et al., 2010). Seventy-six perfect of adults with OCD have another anxiety disorder, 63 percent have a mood disorder (commonly depression), and 23 to 32 percent have a co-morbid obsessive-compulsive personality disorder (Kessler et al., 2005).
Psychotherapy and Psychopharmacological Treatment
For the OCD patient, I would definitely begin to measure OCD symptoms with the Yale-Brown Obsessive Compulsive Scale. There is a self-report scale that clinicians can use which shows good convergent validity as compared to the interview, as well as internal consistency and test-retest reliability. As providers get busier and busier, using a self-report to track efficacy of treatment becomes essential (Steketee et al., 1996).
Therapy is the mainstay of treatment for patients with OCD. CBT may be more effective than SSRI’s or Clomipramine; though many providers use therapy and medication in combination, there is no evidence to show superiority of combination treatment over the most effective psychotherapies (Ming, 2016). The most common type of therapy uses exposure and response prevention (ERP). This treatment leads to the habituation of anxiety related to obsessions so that rituals are no longer necessary to reduce anxiety. Psychoeducation is also important as anxiety may increase during exposure as the client needs to know that the short term “pain” will produce long term “gains” (Gabbard, 2014).
If CBT/ERP is not available, or the patients symptoms are severe enough to warrant medication, SSRI’s are first-line; all of the SSRI’s (except Lexapro and Celexa) have been approved for the treatment of OCD (Soomro et al., 2008). Clomipramine, a tricyclic antidepressant, is a second line option due to it’s increase side effect profile (Stahl, 2018). In general, SSRI’s and Clomipramine leads to improvement in 40-60% of patients with OCD (Pigott, 1999).
