What does psychopathology study?

Psychopathology is a field of study that focuses on the understanding of psychological disorders by examining their causes, symptoms, and treatment. This comprehensive approach allows psychologists and researchers to analyze how mental illnesses develop, what symptoms are associated with various conditions, and the most effective interventions or therapies for those affected. By studying the full spectrum of psychological disorders, psychopathology aims to integrate knowledge from various perspectives, including biological, psychological, and social factors, to provide a holistic understanding of mental health.

While the other options touch on important aspects of psychology, they do not encompass the full scope of what psychopathology studies. Focusing only on treatment neglects the foundational understanding required to address these disorders effectively. Examining only physical symptoms or societal impacts doesn't capture the complexity of the disorders themselves. Therefore, the correct answer encompasses the entirety of psychopathology's objectives and methodologies.
