Q

meta-analysis

A

they answer questions unaddressed by other experiments

  1. “study of studies” - used to extract data and pull info from many studies to get an average effect
  2. AGGREGATE all the data and determine the actual EFFECT SIZE of the intervention
  3. more GENERALIZABLE INFO is obtained
  4. used to evaluate MODERATOR VARIABLES ie. demographic variables

Q

Schmitt et al 2014 - 2 meta-analyses general findings meta analysis 1

A
  1. discrimination negatively associated with wellbeing (r = -.23 from 328 studies)
  2. cross-sectional effects are stronger than longitudinal effects (stronger effects of disc in short term)
  3. effects stronger for disadvantaged groups & mixed versus advantaged groups
  4. racism and sexism equally strongly associated with wellbeing (may not be the strongest, but are equally potent)

Q

Schmitt et al meta-analysis 2 general findings

A

no overall effect of experimental studies

experimental manipulations didn’t do much

but depending on diff factors, did find effects in certain conditions

they were SIGNIFICANT MODERATORS (ie. interactions)

Q

Schmitt et al meta-analysis 2 - significant study moderators

A

manipulations that alluded to PERVASIVENESS of disc had strong neg effects

d = 0.25, k = 23

discrimination attributed to a single event had no effect

Q

de Lange study: distinction between LGBT bias-based victimization and discrimination

A

LGBT bias-based victimization:
- more MAJOR events
- exposure to violence
- physical/verbal harassment
- abuse
…due to LGBT identity

discrimination:
- more DAILY events
- treated unfairly at home
- school
- workplace
…because of LGBT experiences

17
Q

de Lange et al - discrimination against LGBTQ people findings

A

44 studies across all outcomes

  1. LGBT bias-based victimization (major events) related to greater SUICIDAL IDEATION & ATTEMPTS
  2. discrimination (more daily events) NOT RELATED to ideation (k = 3) - too few studies for attempts
  3. general victimization (not related to SGM identity) related to more ideation (k = 9) and more attempts (k = 6)
18
Q

de Lange et al - discrimination against LGBTQ people - diff forms of LGBT disc…

A

present different levels of risk for suicidal ideation and attempts

more major disc (bias-based victimization) related to greater suicidal ideation

19
Q

Mason et al - Eating Pathology meta-analysis setup

A

55 studies looking at relations between DISC and EATING DISORDERS

20
Q

Mason et al - Eating Pathology meta-analysis findings

A

disc associated with greater combined eating disorder pathology

  1. general disc (attribution-free): r = 0.26
  2. racial disc: r = 0.18
  3. gender disc: r = 0.19
  4. weigh disc: r = 0.34
    ^ strongest effect
21
Q

Mason et al - Eating Pathology meta-analysis - strongest effect found between…

A

weight discrimination and eating disorder pathology

r = 0.34

shows that the type of disc you experience moderates the impacts of experiences on health

22
Q

discrimination and substance use

A
  1. gay-related victimization and general victimization associated with substance use in LGB youth
  2. racial disc relates to more substance use among racially minoritized Americans
  3. teacher based racial disc associated with substance use among racially minoritized Americans
23
Q

teacher based racial disc associated with substance use among youth - effect is stronger for…

A
  1. younger kids
  2. black youth

compared to Latinx or Indigenous youth

24
Q

meta-analysis of teacher-based racial-ethnic disc

A

includes:
- wellbeing
- substance use
- academic outcomes

  1. teacher based disc overall related to worse academic outcomes (r = -0.16, k = 138)
  2. effects stronger in schools with FEWER racially minoritized students
25
Q

academic outcomes from Benner’s 2018 meta analysis

A

measured academic wellbeing indicators

  • achievement
  • school engagement
  • motivation

ALL NEGATIVELY IMPACTED BY DISC

26
Q

vicarious racism - parental exposure

A

second-hand racism

living vicariously

27
Q

systematic review of parental racism experiences and child outcomes - maternal experiences of racism pathway

A

pre-birth, maternal pathway

mediators:
- depressive symptoms
- gestational age

moderators:
- ethnicity (Hispanic)

lead to Child/Youth Health Outcomes:
- preterm birth
- cortisol reactivity
- birthweight

28
Q

systematic review of parental racism experiences and child outcomes - vicarious racism pathway

A

post-birth, caregiver pathway

mediators:
- parental mental health
- undesirable parenting practices
- child/youth distress

moderators
- parental ethnic group attachment
- parental acculturation
- child/youth cultural socialization

lead to Child/Youth Health Outcomes

29
Q

systematic review of parental racism experiences and child outcomes - Child/Youth Health Outcomes

A
  1. physical health
  2. mental health
  3. socioemotional health
  4. child/youth development
  5. health care utilization
30
Q

racism is related to _______ physical health

A

compromised

stress neurobiology and racial discrimination

via a couple diff pathways

31
Q

Berger & Sarnyai - HPA pathway by which discrimination leads to poor physical health

A

HPA axis activation = cortisol

3 possibilities
a. normal response
b. exaggerated response (too much)
c. blunted response (too little)

32
Q

pathways by which discrimination leads to poor physical health

A
  1. HPA axis activation > cortisol
  2. heart rate variability (HRV) decreases
  3. disrupted brain networks
33
Q

Berger & Sarnyai - HRV mechanism through which discrimination leads to poor physical health

A

heart rate variability

changes in beat-to-beat intervals, caused by a balance between your symp and parasymp NS

it decreases with age

LOW IN BLACK YOUTH

low HRV = linked to higher risk of stroke, heart failure, other bad cardiovascular outcomes

racial disc = associated with low HRV

34
Q

cortisol and HRV contribute to…

A

inflammatory processes that result in ALLOSTATIC LOAD

35
Q

allostatic load

A

biological wear and tear

36
Q

Berger & Sarnyai - disrupted brain networks - how discrimination leads to poor physical health

A
  1. pre-frontal cortex dysregulation: emotion regulation and stress response
  2. decreased grey matter in anterior cingulate cortex: emotion, impulse control, decision making
37
Q

case example study with minority stress & cortisol setup

A

daily diary study looking at minority stressors

how do daily minority stressors relate to initial cortisol, cortisol awakening response, and diurnal cortisol in SGM young adults?

N = 58 SGM young adults (not from metropolitan areas)

daily dairy study across 7 days

4 cortisol samples per day
- waketime
- 45 mins after waking
- 12 hours after waking
- bedtime

38
Q

case example study with minority stress & cortisol findings

A
  1. minority stress associated with HIGHER WAKING CORTISOL (bad)
  2. NO IMPACT on cortisol awakening response
  3. no diffs 12 hours after waking
  4. no diffs at bedtime
  5. NON-MINORITY STRESSORS predict greater evening cortisol
39
Q

case example with minority stress & cortisol takeaways

A
  1. exposure to minority stressors contributes to HIGHER CORTISOL at WAKETIME
    - may be the body anticipating/prepping for high stress exposure
  2. CORTISOL AWAKENING RESPONSES (CAR) is normal (good)
  3. cortisol levels back to normal by evening & bedtime DESPITE HIGH MINORITY STRESS
    - non-general stress adds on and leads to higher evening cortisol in this sample, however
  4. nonetheless, study demonstrates DISRUPTION and OVERPRODUCTION of CORTISOL AT WAKETIME for those experiencing minority stressors

^may have longer term implications
