Abnormal Psychology Concepts: Then and Now

 Robert Fettgather, PhD, has served as an associate faculty member at Mission College in Santa Clara, California, since 1983. When he is not leading courses in general, developmental, and abnormal psychology, among other subjects, Robert Fettgather enjoys hiking and boating.

Abnormal psychology is a distinct branch of psychology focused on atypical behavioral patterns and uncommon emotions and thoughts that may qualify as mental disorders. 

In modern times, aspects of this psychological discipline can be traced back to Karl Jaspers, who published the book General Psychopathology in 1913. It was an instrumental title in reframing interpretations of individual mental experiences, particularly those that might be considered unusual or out of the ordinary. Over the course of more than a century, the discipline has evolved to emphasize in-depth, medical-based studies of various mental illnesses, which may be caused by factors as diverse as genetics and social influence.

Psychopathology is the focus on the underlying disease processes or pathology, causing the abnormal behavior. Abnormal psychologists may study several clinical and personality disorders. One of the most common behavioral disorders in the United States is attention deficit hyperactivity disorder (ADHD). ADHD refers to impulsive actions and the inability to focus on a single topic or activity. It is usually diagnosed and treated in childhood, with a prevalence rate of approximately 9.4 percent. However, a 2019 study found that ADHD prevalence in adults had nearly reached 1 percent, doubling over a decade. It is not clear whether the trend represents sound medicine or diagnostic inflation. Personality disorders include obsessive-compulsive personality disorder (OCPD), narcissistic personality disorder, and borderline personality disorder. Interestingly, OCPD is different than a similarly named disorder, obsessive compulsive disorder (OCD). OCPD is characterized by a preoccupation with perfectionism and a staunch dedication to rules and standards. Behaviors associated with OCD include repeated obsessions and compulsions. Treatment options for OCD generally involve exposure and response prevention, cognitive behavioral therapy, and a regimen of selective serotonin reuptake inhibitors.

Historically, abnormal psychology was preceded by various religious traditions including shamanism that involved rituals such as incantations and exorcisms. Trephining, involving drilling a hole directly into the skull, was utilized as an attempt to promote healing by the early Greeks and the Chinese. Primitive and dangerous ancient methods can overshadow reasonable contributions from Tradiotional Chinese Medicine, including some herbal interventions.
