Diathesis-Stress Model: This model suggests that individuals inherit a genetic predisposition (diathesis) for a disorder but require exposure to specific stressors in their environment for the disorder to manifest.
Biopsychosocial Model: This model considers biological factors (genetics), psychological factors (thoughts, emotions), and social factors (environmental context) as all playing a role in the development of psychological disorders.
Epigenetics: Epigenetics explores how environmental influences can cause changes in gene expression without altering DNA sequences, potentially impacting an individual's susceptibility to certain disorders.
