A practical, evidence-based introduction to psychological disorders, diagnosis, and care.

This course begins with the foundations of Abnormal Psychology, helping you define abnormal behavior and understand why context, culture, and controversy matter in mental health. You will trace the historical shift from asylums to modern care, then examine how classification and diagnosis work through DSM and ICD systems. These early lessons build the framework you need to approach psychological disorders with accuracy and confidence.

You will also develop a stronger grasp of clinical assessment methods, including interviews, psychological tests, and observation, along with the research methods used to build reliable evidence in Psychology. From there, the course moves through major disorder categories such as anxiety disorders, obsessive-compulsive and related disorders, trauma- and stressor-related disorders, mood disorders, psychotic disorders, personality disorders, somatic symptom and dissociative disorders, eating disorders, and substance use and addictive behaviours. Each topic is introduced in a way that connects symptoms, causes, and treatment considerations to everyday clinical understanding.

In addition, you will study developmental and child psychopathology, the biological, psychological, and social causes of mental disorders, and the main treatment approaches used in contemporary care, including psychotherapy and medication. The course closes with ethics, culture, and stigma, giving you a responsible and informed perspective on mental health in society. By completing this course, you will think more clearly about abnormal behavior, speak more confidently about mental health, and approach Psychological topics with greater insight, empathy, and analytical skill.
