the biopsychosocial approach
The biopsychosocial approach is a broad concept that aims to study the cause or progress of disease using biological factors (genetic, biochemical, etc.), psychological factors (mood, personality, behavior, etc.) and social factors ( cultural, family, socioeconomic, medical, etc). The biopsychosocial approach, as opposed to the biomedical model, which attributes disease only to biological factors such as viruses, genes, or somatic abnormalities, covers disciplines ranging from medicine to psychology to sociology.
