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.{{Cite journal|last1=Chen|first1=Edith|last2=Miller|first2=Gregory E.|date=2012-03-01|title="Shift-and-Persist" Strategies: Why Being Low in Socioeconomic Status isn't Always Bad for Health|journal=Perspectives on Psychological Science|volume=7|issue=2|pages=135–158|doi=10.1177/1745691612436694|issn=1745-6916|pmc=3491986|pmid=23144651}}{{Cite journal|last1=Chen|first1=Edith|last2=Miller|first2=Gregory E.|last3=Lachman|first3=Margie E.|last4=Gruenewald|first4=Tara L.|last5=Seeman|first5=Teresa E.|date=2012|title=Protective Factors for Adults From Low-Childhood Socioeconomic Circumstances: The Benefits of Shift-and-Persist for Allostatic Load|journal=Psychosomatic Medicine|language=en|volume=74|issue=2|pages=178–186|doi=10.1097/PSY.0b013e31824206fd|issn=0033-3174|pmc=3273596|pmid=22286848}} A large body of research has previously linked low socioeconomic status to poor physical and mental health outcomes, including early mortality.{{Cite journal|last1=Adler|first1=Nancy E.|last2=Boyce|first2=Thomas|last3=Chesney|first3=Margaret A.|last4=Cohen|first4=Sheldon|last5=Folkman|first5=Susan|last6=Kahn|first6=Robert L.|last7=Syme|first7=S.

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 a stressor or reduce its emotional impact. These shift strategies particularly focus on changing one's response to a stressor, instead of attempting to change the situation or stressor itself.{{Cite journal|last1=Heckhausen|first1=J.|last2=Schulz|first2=R.|date=1995|title=A life-span theory of control|journal=Psychological Review|volume=102|issue=2|pages=284–304|doi=10.1037/0033-295x.102.2.284|issn=0033-295X|pmid=7740091}}{{Cite journal|last1=Heckhausen|first1=Jutta|last2=Wrosch|first2=Carsten|last3=Schulz|first3=Richard|date=2010|title=A motivational theory of life-span development|journal=Psychological Review|volume=117|issue=1|pages=32–60|doi=10.1037/a0017668|issn=1939-1471|pmc=2820305|pmid=20063963}} As shift strategies depend more on internal processes (self-control and regulation), than external resources, it is hypothesized that shift strategies may be particularly adaptive responses to the chronic, uncontrollable stressors that are associated with low socioeconomic status.
Persist strategies
Measurement
To evaluate the combination of shift-and-persist strategy use, distinct "shift" and "persist” constructs were initially measured separately by using multiple, self-report measures of reappraisal, emotional reactivity, and future orientation in early research on this model.
In 2015, Chen and colleagues published the Shift-and-Persist Scale, which is a combined self-report measure that assesses both shift and persist strategies.{{Cite journal|last1=Chen|first1=Edith|last2=McLean|first2=Kate C.|last3=Miller|first3=Gregory E.|date=2015|title=Shift-and-Persist Strategies: Associations With Socioeconomic Status and the Regulation of Inflammation Among Adolescents and Their Parents|journal=Psychosomatic Medicine|language=en|volume=77|issue=4|pages=371–382|doi=10.1097/PSY.0000000000000157|pmid=26167560|pmc=5890430|issn=0033-3174}} The Shift-and-Persist Scale has been validated for use with adults and teenagers. The questionnaire asks respondents to rate how well 14 statements about various approaches to dealing with life stressors apply to them on a 1-4 scale.{{Cite web|url=http://sparqtools.org/mobility-measure/shift-and-persist-teen-adult/|title=Shift and Persist (Teen, Adult) {{!}} SPARQTools|last1=University|first1=© Stanford|last2=Stanford|website=sparqtools.org|language=en|access-date=2019-11-08|last3=California 94305}} Out of the 14 items on the measure, 4 assess a respondent's use of shift strategies, 4 load onto persist strategies, and 6 items are non-relevant distractors that are ignored during scoring. When scoring the Shift-and-Persist Scale, one item (#4) is reverse-scored. This scale is publicly available online.
A simplified 5-item Shift-and-Persist scale has also been published for use with younger children and adolescents (ages 9–15).{{Cite web|url=http://sparqtools.org/mobility-measure/shift-and-persist-child/|title=Shift and Persist (Child) {{!}} SPARQTools|last1=University|first1=© Stanford|last2=Stanford|website=sparqtools.org|language=en|access-date=2019-11-08|last3=California 94305}} Total scores on this version of the Shift-and-Persist Scale range from 0-20, such that higher scores are indicative of greater use of shift-and-persist strategies.

The shift-and-persist model mainly hypothesizes that these strategies have protective effects for the health of low socioeconomic status individuals because they affect biological and physiological stress response tendencies that are relevant for disease. There is some evidence that shift responses (e.g., reappraisal) to acute stressors are associated with attenuated physiological responses to stress, including reduced cardiovascular reactivity.{{Cite journal|last=Gross|first=J.

= Enhancement of adaptive biological stress-recovery systems =
Another alternative, but not mutually exclusive hypothesis, is that shift-and-persist strategies affect health by increasing or up-regulating biological responses that enhance stress recovery and resilience. In particular, the parasympathetic nervous system's functioning may be enhanced by shift-and-persist response tendencies. Emotion regulation abilities that are consistent with shift-coping have been linked to greater parasympathetic nervous system functioning at rest, as indexed by higher levels of high-frequency heart rate variability.{{Cite journal|last1=Appelhans|first1=Bradley M.|last2=Luecken|first2=Linda J.|date=2006|title=Heart Rate Variability as an Index of Regulated Emotional Responding|journal=Review of General Psychology|volume=10|issue=3|pages=229–240|doi=10.1037/1089-2680.10.3.229|s2cid=3926266|issn=1089-2680}} Further, the parasympathetic nervous system is highly integrated with, and may contribute to the down-regulation of hypothalamic–pituitary–adrenal axis and immune system stress responses that influence allostatic load over time.{{Cite journal|last1=THAYER|first1=J.

The oxytocin system has also been identified as another potential mechanism by which shift-and-persist strategies could influence health outcomes. Oxytocin is a hormone that has been linked to a wide range of positive social and emotional functions and can be used to effectively attenuate hypothalamic–pituitary–adrenal axis and sympathetic nervous system responses to stress.{{Cite journal|last1=Ditzen|first1=Beate|last2=Schaer|first2=Marcel|last3=Gabriel|first3=Barbara|last4=Bodenmann|first4=Guy|last5=Ehlert|first5=Ulrike|last6=Heinrichs|first6=Markus|date=2009-05-01|title=Intranasal oxytocin increases positive communication and reduces cortisol levels during couple conflict|journal=Biological Psychiatry|volume=65|issue=9|pages=728–731|doi=10.1016/j.biopsych.2008.10.011|issn=1873-2402|pmid=19027101|s2cid=22547391}}{{Cite journal|last1=Ross|first1=Heather E.|last2=Young|first2=Larry J.|date=2009-10-01|title=Oxytocin and the neural mechanisms regulating social cognition and affiliative behavior|journal=Frontiers in Neuroendocrinology|series=Hormones & Social Behavior|volume=30|issue=4|pages=534–547|doi=10.1016/j.yfrne.2009.05.004|pmid=19481567|pmc=2748133|issn=0091-3022}}{{Cite journal|last1=Gutkowska|first1=Jolanta|last2=Jankowski|first2=Marek|date=2008|title=Oxytocin revisited: It is also a cardiovascular hormone|journal=Journal of the American Society of Hypertension |volume=2|issue=5|pages=318–325|doi=10.1016/j.jash.2008.04.004|issn=1933-1711|pmid=20409913}} However, there is little research examining the interplay between shift-and-persist strategy use and the oxytocin system.

It has also been proposed that shift-and-persist strategies may buffer health outcomes in individuals of low socioeconomic status by affecting health behaviors. Previous research has demonstrated that, regardless of socioeconomic status, individuals with emotion regulation difficulties are also likely to engage in poorer health behaviors, including over-eating, sedentary lifestyle, risky sexual health behaviors, and drug use.{{Cite journal|last1=Rizor|first1=Asha|last2=Callands|first2=Tamora|last3=Desrosiers|first3=Alethea|last4=Kershaw|first4=Trace|date=2017-07-03|title=(S)He's Gotta Have It: Emotion Regulation, Emotional Expression, and Sexual Risk Behavior in Emerging Adult Couples|journal=Sexual Addiction & Compulsivity|volume=24|issue=3|pages=203–216|doi=10.1080/10720162.2017.1343700|pmid=31662601|pmc=6818717|issn=1072-0162}}{{Cite journal|last1=Casagrande|first1=Maria|last2=Boncompagni|first2=Ilaria|last3=Forte|first3=Giuseppe|last4=Guarino|first4=Angela|last5=Favieri|first5=Francesca|date=2019-08-31|title=Emotion and overeating behavior: effects of alexithymia and emotional regulation on overweight and obesity|journal=Eating and Weight Disorders|volume=25|issue=5|pages=1333–1345|doi=10.1007/s40519-019-00767-9|issn=1590-1262|pmid=31473988|s2cid=201692793}}{{Cite journal|last1=Harvey|first1=Samuel B.|last2=Hotopf|first2=Matthew|last3=Øverland|first3=Simon|last4=Mykletun|first4=Arnstein|date=2010|title=Physical activity and common mental disorders|journal=British Journal of Psychiatry|language=en|volume=197|issue=5|pages=357–364|doi=10.1192/bjp.bp.109.075176|pmid=21037212|issn=0007-1250|doi-access=free}}{{Cite journal|last=Bechara|first=Antoine|date=2005-10-26|title=Decision making, impulse control and loss of willpower to resist drugs: a neurocognitive perspective|journal=Nature Neuroscience|volume=8|issue=11|pages=1458–1463|doi=10.1038/nn1584|pmid=16251988|s2cid=641014|issn=1097-6256}} Individuals of low socioeconomic status who learn to regulate their emotions more effectively, by using "shift" strategies in childhood, may be more likely than their peers with emotion regulation difficulties to establish and sustain positive health behaviors throughout development.

Since 2012, integrative research groups concerned with clinical health psychology, social psychology, psychoneuroimmunology, and public health have begun to evaluate the relationships postulated by the shift-and-persist model. The majority of empirical studies on this topic test whether shift-and-persist strategies are associated with differential health outcomes in low vs. high socioeconomic status samples.
Thus far, high levels of shift-and-persist strategy use have been linked to:
- Lower total allostatic load in adults who grew up in low, but not high, socioeconomic status households.{{Cite journal|last1=Chen|first1=Edith|last2=Miller|first2=Gregory E.|last3=Lachman|first3=Margie E.|last4=Gruenewald|first4=Tara L.|last5=Seeman|first5=Teresa E.|date=2012|title=Protective factors for adults from low-childhood socioeconomic circumstances: the benefits of shift-and-persist for allostatic load|journal=Psychosomatic Medicine|volume=74|issue=2|pages=178–186|doi=10.1097/PSY.0b013e31824206fd|issn=1534-7796|pmc=3273596|pmid=22286848}}

Although it has been proposed that a variety of psychological interventions for at-risk youth of low socioeconomic status may reduce health disparities, in part, by increasing shift-and-persist tendencies in families, the majority of studies on shift-and-persist have been cross-sectional. Therefore, it remains unknown if shift-and-persist strategies play a causal role in reducing the negative impact of low socioeconomic status on health.{{Cite journal|last1=Miller|first1=Gregory E.|last2=Brody|first2=Gene H.|last3=Yu|first3=Tianyi|last4=Chen|first4=Edith|date=2014-08-05|title=A family-oriented psychosocial intervention reduces inflammation in low-SES African American youth|journal=Proceedings of the National Academy of Sciences|language=en|volume=111|issue=31|pages=11287–11292|doi=10.1073/pnas.1406578111|issn=0027-8424|pmid=25049403|pmc=4128159|bibcode=2014PNAS..11111287M|doi-access=free }} More longitudinal and treatment studies are needed to evaluate directional and causal hypotheses based upon the shift-and-persist model.
