Racediskrimination og stressreaktion

Racediskrimination og dysreguleret stressreaktion: Risiko/beskyttelsesfaktorer
Målet med denne undersøgelse er at lære om, hvorvidt unge med etniske minoriteters racediskriminationsoplevelse er relateret til dysregulerede biologiske reaktioner på subtil racisme, og hvordan forholdet kan svækkes eller forværres af et sæt sociale og kognitive faktorer. De vigtigste spørgsmål, den sigter mod at besvare er:
- at afsløre forholdet mellem racediskriminationsoplevelser og etniske minoritetsunges stressreaktion på subtil racisme
- at teste forældrenes etnisk-racesocialisering, børns tilskrivning til subtil racisme og deres raceidentitet som potentielle risiko- og beskyttende faktorer.

Detaljeret beskrivelse
Erfaringer med racediskrimination udgør betydelige risici for etniske minoritetsunges fysiske og psykiske helbredsproblemer. En forklaring antyder, at kronisk stress kan føre til ændrede, dysregulerede stressreaktioner, som kan gøre individer modtagelige for helbredsproblemer. I øjeblikket er der ingen eksperimentel undersøgelse, der udtømmende måler etniske minoritetsunges stressreaktion på subtil racisme eller undersøger de bidragende roller af racediskriminationsoplevelse og mulige risiko- og beskyttende faktorer.
En fællesskabsprøve af 11-14-årige etniske minoritetsunge (40 latinamerikanske, 40 sorte/afrikanske amerikanske) og deres forældre vil blive rekrutteret. Undersøgelsen anvender en tilpasset peer-afvisningsopgave, som er blevet meget brugt med unge, og omhyggeligt designet til at fremkalde oplevelsen af subtil racediskrimination fra hvide jævnaldrende. Teenageres kardiovaskulære aktivitet og spytprøver vil blive taget på flere tidspunkter før, under og efter peer-afvisningsopgaven, idet der trykkes på respons, der involverer hypothalamus-hypofyse-binyre (HPA) aksen, autonomt nervesystem (ANS) og inflammatorisk mediator ( JEG ER). Unge vil rapportere deres racediskriminationsoplevelse, komme med tilskrivninger om oplevelsen af peer-afvisning og vurdere deres raceidentitet. Forældre vil udfylde et spørgeskema for at rapportere deres etnisk-raciale socialiseringspraksis.
Målene med dette forslag er: 1) Afsløre forholdet mellem racediskriminationsoplevelser og unge med etniske minoriteters stressreaktion på subtil racisme; og 2) Test forældrenes etnisk-racesocialisering, børns tilskrivning til subtil racisme og deres raceidentitet som potentielle risiko- og beskyttende faktorer.

Eksperimentel: stress inducing task
Adolescents will complete an adapted peer rejection task on the computer to elicit the experience of subtle racial discrimination from White peers, then discuss the peer rejection task with parents, as well as an impossible puzzle task to elicit cognitive stress.
|
Peer rejection task: Adolescents will be informed that two peers will take turns to choose who they will chat with for different topics. Participants will not be chosen by virtual White peers 75% of the time. In reality, White peers are computerized avatars and whether or not adolescents are chosen by those peers is programmed with PsychoPy software. Conversation about peer rejection: parents and adolescents will discuss the peer rejection task guided with suggested question prompts. Impossible puzzle task: Adolescents will be asked to fit all puzzle pieces into a wooden frame with a wrong piece provided. |
