Kleinman’s three sectors
Who named what: Arthur Kleinman (1980) split every health system into popular, folk and professional sectors and gave clinicians the explanatory model interview. Charles Leslie (1976) named medical pluralism. Lola Romanucci-Ross (1969) described the hierarchy of resort — the order in which people try therapies. John Janzen (1978) showed that a therapy management group of kin, not the patient alone, does the choosing.
