What is a common intrapersonal factor contributing to depression according to depression theory?

A common intrapersonal factor contributing to depression, according to depression theory, is the loss of self-esteem or security. This aspect plays a crucial role in mental health, as self-esteem is integral to how individuals perceive themselves and their worth. When a person experiences a decline in self-esteem, they may feel inadequate, hopeless, or worthless, all of which can lead to feelings of depression. This internal struggle can create a negative feedback loop, where low self-esteem exacerbates depressive symptoms, further diminishing one's sense of security in various aspects of life.

In contrast, focusing on positive self-affirmations typically helps in building self-esteem and fostering a more positive self-image, making it less likely to contribute to depression. Excessive social interactions can also be a protective factor for mental health, as social support often mitigates feelings of isolation. High energy levels and motivation are generally indicative of a positive mental state, which is contrary to what one typically experiences during episodes of depression. Thus, the loss of self-esteem or security stands out as a significant contributor to depression from an intrapersonal perspective.
