Behavioral Integration in Medicine era
George Engel's biopsychosocial model, articulated in the late 1970s, reframed illness as the result of interacting biological, psychological, and social factors and urged integration of psychology into medical care. Albert Bandura contributed a cognitive-behavioral framework with emphasis on self-regulation and self-efficacy, shaping interventions to improve adherence and coping in clinical settings. Aaron Antonovsky's sense of coherence theory offered a sociocultural lens on coping, resilience, and health trajectories that informed preventive and rehabilitative approaches. David Mechanic's work on illness experiences and the doctor-patient relationship provided a bridge between sociocultural determinants and practical communication and collaborative care in medicine.
