Janna has low self-esteem because she is often teased for being overweight. Appreciating the complexity of Janna's difficulties requires A) introspection. B) psychoanalysis. C) massed practice. D) a biopsychosocial approach.

The correct answer is letter D

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