Limitations: reductionist model, not easily testable, based on case studies.
Biological: treats abnormality as a medical/physical condition. Caused by genetics, chemicals, infections.
Strengths: no blame on the patient, treatment is effective.
Limitations: reductionist model, inconclusive evidence (concordance is never 100%).

Abnormality: Behavioural
Behavioural: abnormal behaviours are learned through conditioning or social learning. Maladaptive behaviours are learned and reinforced e.g. phobias.
Limitations: focuses only on the outcome/effect, not the underlying cause. Blame on the individual for 'learning' their disorder.
