The Biopsychosocial Model
Diathesis-Stress Model:
Diathesis: An inherited predisposition or vulnerability.
Stress: Environmental stressors.
Development of Disorder: The stronger the diathesis, the less stress is needed to trigger the disorder.

Prenatal trauma.
Childhood sexual or physical abuse.
Family conflict.
Significant life changes.
The Diathesis-Stress Model
Definition: A disorder develops when an underlying vulnerability is coupled with a precipitating event.
Onset of Mental Disorders: Occurs due to both vulnerability and stressful events.
Assessment and Categorization of Disordered Thoughts, Emotions, and/or Behaviors
Assessment:
Categorize thoughts, emotions, and behaviors to make a diagnosis.
