Adjustment disorders

Adjustment disorder is the diagnosis that lives between normal stress and a full-blown disorder. It's the exam's favorite "none of the above" answer — reach for it when there's a clear stressor and a reaction that's too big to shrug off but doesn't meet criteria for anything else.

The definition hinges on the stressor and the clock. Emotional or behavioral symptoms develop within 3 months of an identifiable stressor (a breakup, job loss, move, diagnosis, financial trouble). The reaction is out of proportion to the stressor's severity or causes significant impairment in functioning — either qualifier counts. Crucially, once the stressor or its consequences ends, symptoms resolve within 6 months. If they persist beyond that, it's no longer an adjustment disorder.

Adjustment disorder comes with specifiers naming the predominant feature: with depressed mood, with anxiety, with mixed anxiety and depressed mood, with disturbance of conduct, with mixed disturbance of emotions and conduct, and unspecified.

The differentiation is what earns points. It's a diagnosis of exclusion: if the presentation meets criteria for another disorder (MDD, GAD, PTSD), you diagnose that instead. Distinguish it from normal stress reactions, which are proportionate and don't cause marked impairment. And separate it from bereavement — uncomplicated grief after a loss is not an adjustment disorder unless the reaction clearly exceeds expected norms. Think of adjustment disorder as the residual, time-limited, stressor-linked category.

Clinical Pearl: Adjustment disorder = symptoms within 3 months of an identifiable stressor that are out of proportion or impairing, and that resolve within 6 months after the stressor ends. It's a diagnosis of exclusion — if full criteria for another disorder are met, diagnose that instead.
