Psychotherapists apply several techniques and modelling techniques to assist clients facing mental, neurological and substance use disorders.
One of these, the biopsychosocial model, is a holistic framework for understanding health and illness by examining the interplay of biological, psychological, and social factors.
Developed by George Engel in 1977, it challenges reductionist biomedical approaches by emphasising that health outcomes arise from dynamic interactions across these three domains.
These include the biological domain, which looks at genetic predispositions, physiological processes, and disease pathology.
