This paper examines three major models of mental illness — humanistic, behavioral, and psychodynamic — along with their corresponding therapeutic approaches. The humanistic model, rooted in existential philosophy, emphasizes personal perception, freedom of choice, and self-actualization, and gives rise to humanistic psychotherapy. The behavioral model, grounded in classical and operant conditioning, attributes mental illness to faulty stimulus-response associations and reinforcement patterns, leading to behavior modification and cognitive-behavioral therapies. The psychodynamic model, originating with Sigmund Freud, traces mental illness to unconscious conflicts, developmental fixations, and imbalances among the id, ego, and superego, and is associated with verbal psychotherapy. Together, these three frameworks provide a broad foundation for understanding and treating mental illness.
Mental illness is one of the most important health issues in North America today. It can have an enormous impact on the personal and professional lives of millions of individuals. As such, an understanding of the three most common models of mental illness — humanistic, behavioral, and psychodynamic — is important to understanding the concept of mental illness as a whole. Each model also gives rise to distinct therapeutic modalities that guide clinical practice.
The humanistic model of mental illness derives from existential philosophy and first emerged in the United States in the 1950s and 1960s. This model is centered on the idea that a person's reality comes from their unique perception of the world around them. Freedom of choice means that individuals are able to make decisions and be responsible for their personal actions. The humanistic model focuses on the actualizing tendencies of humans to grow and explore personal potential.
In the humanistic model, abnormal behavior and mental illness arise from several different factors. Mental illness can emerge when society begins to regard certain people or groups as more valuable or powerful than others. Further, mental illness can stem from an individual's unhealthy need to derive self-regard from other people. Thus, a state of incongruence develops from the difference between inherent self-worth and self-worth as measured through the perceived opinions of others (Carson).
The principal therapeutic modality arising from the humanistic model is humanistic psychotherapy, sometimes referred to as experiential, Gestalt, or existential therapy. Humanistic therapy focuses on the immediate feelings and experiences of the patient, rather than on the past or on thoughts and behaviors. The relationship between the therapist and patient is crucial in this form of therapy (Surgeon General).
The behavioral learning model is shaped largely by the concepts of classical conditioning and operant conditioning. The classical conditioning model originated in Ivan Pavlov's famous experiments with salivating dogs and offers a largely mechanistic description of stimuli and responses that produce behavior. In this framework, mental illness arises from inappropriate associations between stimuli and responses. The operant conditioning model comes from the work of B.F. Skinner, who argued that behaviors are produced by the events that follow them. Reinforcement plays a central role in this theory, and mental illness is understood as the product of incorrect reinforcement patterns (Carson; Abnormal Psychology).
