Sverre Lysgaard, a Norwegian sociologist, first proposed the U-curve model for adjustment in 1955, and subsequent researchers have developed it over the ensuing decades (e.g. Oberg, 1960; Chang, 1973). This model proposes four stages for the adaptation process: honeymoon, crisis, integration, and integration.
