Shift-and-persist model
The Shift-and-persist model has emerged in order to account for unintuitive, positive health outcomes in some individuals of low socioeconomic status. A large body of research has previously linked low socioeconomic status to poor physical and mental health outcomes, including early mortality. Low socioeconomic status is hypothesized to get "under the skin" by producing chronic activation of the sympathetic nervous system and hypothalamic–pituitary–adrenal axis, which increases allostatic load, leading to the pathogenesis of chronic disease. However, some individuals of low socioeconomic status do not appear to experience the expected, negative health effects associated with growing up in poverty. To account for this, the Shift-and-Persist Model proposes that, as children, some individuals of low socioeconomic status learn adaptive strategies for regulating their emotions ("shifting") and focusing on their goals ("persisting") in the face of chronic adversity. According to this model, the use of shift-and-persist strategies diminishes the typical negative effects of adversity on health by leading to more adaptive biological, cognitive, and behavioral responses to daily stressors. Shift strategies Broadly, "shift" strategies encompass a variety of cognitive and emotion self-regulation approaches that individuals use to deal with stress, including cognitive restructuring, reframing, reappraisal, and acceptance strategies, which change the meaning of
