What is the biopsychosocial model of psychological disorders?

The biopsychosocial model proposes that psychological disorders result from the interaction of biological, psychological, and social factors rather than any single cause. Biological factors include genetics, brain chemistry, neurotransmitter imbalances, and brain structure abnormalities. Psychological factors include learned behaviors, cognitive patterns, coping styles, and personality traits. Social factors include childhood experiences, trauma, family dysfunction, poverty, cultural norms, and social support.
