What is a common characteristic of psychotic depression?

A common characteristic of psychotic depression is the presence of psychotic features, which may include delusions or hallucinations. In this case, the belief in being held captive by a foreign entity represents a type of delusion. Individuals suffering from psychotic depression may have distorted perceptions of reality that significantly impact their thoughts and behaviors, thereby aligning with the psychotic aspect of the disorder.

The other options do not accurately reflect the typical features of psychotic depression. For instance, a lack of interest in self-care and personal grooming is more indicative of general depressive symptoms rather than the psychotic element. Experiencing a euphoric emotional state contradicts the depressive components of psychotic depression, which generally involve low mood and despair. Similarly, a tendency to form strong social connections does not align with the isolation and withdrawal often seen in those with depression, particularly when psychotic features are present.
