According to the self-regulatory perseveration theory of depression:

A) depression occurs when people shift all their attention away from their self-concept.
B) ego depletion is the primary cause of depression.
C) depression is the result of the inability to find any meaningful goal to commit to.
D) depression results from an inability to disengage from a goal that the person cannot achieve.

The self-regulatory perseveration theory of depression proposes that depression results from an inability to disengage from a goal that the person cannot achieve. This may lead to rumination and continued focus on negative thoughts and emotions, further exacerbating the depression. The theory suggests that individuals with depression may benefit from interventions aimed at helping them to disengage from unattainable goals and redirect their focus towards more achievable ones.
