cueprepAP Psychology Unit 8: Clinical Psychology — Complete Review
Unit 8 is the second-largest unit on the AP exam and covers psychological disorders and their treatment. You'll learn how abnormal behavior is defined (statistical rarity, maladaptiveness, personal distress, deviation from social norms) and classified using the DSM-5, and you'll study the major categories of psychological disorders.
The disorders you need to know include anxiety disorders (generalized anxiety, specific phobias, social anxiety, panic disorder), obsessive-compulsive disorder, PTSD, major depressive disorder, bipolar disorder, schizophrenia, dissociative disorders (especially dissociative identity disorder), somatic symptom disorders, personality disorders (especially antisocial and borderline), eating disorders (anorexia and bulimia), and substance use disorders. For each, know the symptoms, key features, and how different perspectives (biological, psychological, sociocultural) explain them.
The treatment section covers biomedical therapies (psychopharmacology — antidepressants, antipsychotics, anxiolytics, mood stabilizers — plus ECT and psychosurgery) and psychotherapies (psychoanalytic/psychodynamic, humanistic/client-centered, behavioral including systematic desensitization and token economies, cognitive including Beck's CBT and Ellis' REBT, and group/family therapy). Understanding which therapy best matches which disorder is a common exam question.
Key Concepts
DSM-5
The Diagnostic and Statistical Manual of Mental Disorders, used by clinicians to diagnose psychological disorders based on specific symptom criteria.
Anxiety Disorders
Characterized by excessive fear and anxiety. Includes generalized anxiety disorder (persistent worry), specific phobias, social anxiety disorder, and panic disorder (sudden panic attacks).
Major Depressive Disorder
Persistent depressed mood or loss of interest lasting at least two weeks, with changes in sleep, appetite, energy, concentration, and feelings of worthlessness.
Schizophrenia
A severe disorder with positive symptoms (hallucinations, delusions, disorganized speech) and negative symptoms (flat affect, social withdrawal, reduced motivation). Linked to dopamine hypothesis and brain abnormalities.
Bipolar Disorder
Alternating episodes of mania (elevated mood, increased energy, risky behavior) and depression. Different from major depressive disorder because of the manic episodes.
Cognitive Behavioral Therapy (CBT)
Combines cognitive therapy (challenging irrational thoughts — Beck, Ellis) with behavioral techniques. The most empirically supported therapy for many disorders.
Systematic Desensitization
A behavioral therapy for phobias: the client learns relaxation techniques and then gradually faces feared stimuli while remaining relaxed (counterconditioning based on classical conditioning).
Psychopharmacology
Drug treatments: SSRIs for depression/anxiety, antipsychotics for schizophrenia, benzodiazepines for anxiety, lithium/mood stabilizers for bipolar disorder.

Frequently Asked Questions
What is AP Psychology Unit 8 about?
Unit 8 covers clinical psychology — psychological disorders and their treatment. You'll study how disorders are defined and classified (DSM-5), major categories of disorders (anxiety, mood, schizophrenia, dissociative, personality, eating, substance), and treatment approaches (psychotherapy and biomedical therapies).
How much of the AP Psychology exam is Unit 8?
Unit 8: Clinical Psychology accounts for approximately 12–16% of the AP Psychology exam, making it one of the two most heavily weighted units.
What psychological disorders are most tested on the AP Psychology exam?
The most heavily tested disorders include major depressive disorder, generalized anxiety disorder, specific phobias, OCD, PTSD, schizophrenia, bipolar disorder, and dissociative identity disorder. Know the symptoms, causes from multiple perspectives, and appropriate treatments for each.
What is the difference between psychotherapy and biomedical therapy?
Psychotherapy uses psychological techniques (talk therapy, behavioral interventions, cognitive restructuring) to treat disorders. Biomedical therapy uses medical interventions like medications (SSRIs, antipsychotics), electroconvulsive therapy (ECT), or in rare cases, psychosurgery. Many patients benefit from a combination of both approaches.
