PSY330 Exam 1 Study Guide (Ch. 1, 3, 4) – Abnormal Psychology | Models, Diagnosis, Assessment & DSM-5 | 2025 Notes

This detailed study guide covers material from Chapters 1, 3, and 4 for PSY330 – Abnormal Psychology, expertly structured to prepare students for Exam 1. It begins with the four criteria of abnormality (deviance, distress, dysfunction, danger) and introduces foundational concepts such as the biopsychosocial model, cultural relativism, and historical views of mental illness—from ancient demonology to modern pharmacotherapy. The distinction between eccentric and abnormal behavior is clarified, as well as the importance of context and cultural norms in diagnosing disorders. Chapter 3 introduces the five major theoretical models of abnormal psychology: biological, psychodynamic, cognitive-behavioral, humanistic-existential, and sociocultural. Each model includes its assumptions, treatment methods, strengths, and limitations. Students learn about neurotransmitter imbalances, brain structures, unconscious conflicts, conditioning, irrational beliefs, self-actualization, and the role of societal influences. The biopsychosocial and developmental psychopathology models are also introduced for a comprehensive framework. Chapter 4 focuses on clinical assessment and diagnosis, including types of interviews (structured vs unstructured), clinical tests (projective, personality inventories like MMPI, neuropsychological, response inventories, intelligence tests), and observations. Key psychometric properties such as reliability, validity, and standardization are emphasized. The guide explains how the DSM-5 organizes mental disorders, discusses diagnostic tools and limitations, and addresses concerns such as misdiagnosis, stigma, and cultural bias in assessment. This document is ideal for: – Students enrolled in PSY330 or any Abnormal Psychology course – Psychology, Pre-Med, Nursing, Counseling, or Social Work majors – Learners preparing for midterms or unit exams on mental health, models, and diagnosis – Courses that use DSM-5 and evidence-based assessment strategies Keywords: PSY330, abnormal psychology, 4 Ds of abnormality, biopsychosocial model, DSM-5, clinical assessment, mental disorder, diagnosis, psychodynamic model, cognitive behavioral model, biological model, humanistic therapy, sociocultural perspective, cultural bias, psychological testing, MMPI, projective tests, IQ tests, neuropsychological assessment, psychopharmacology, Freud, ego defense mechanisms, therapy models
