人種差別とストレス反応
人種差別とストレス反応の調節不全:リスク/保護因子
この研究の目的は、少数民族の思春期の若者の人種差別の経験が、微妙な人種差別に対する調節不全の生物学的反応に関連しているかどうか、および一連の社会的および認知的要因によってその関係がどのように弱められたり悪化したりするかについて学ぶことです。 回答を目指す主な質問は次のとおりです。
- 人種差別の経験と少数民族の若者の微妙な人種差別に対するストレス反応との関係を明らかにする
- 親の民族的人種的社会化、微妙な人種差別への子供の帰属、および潜在的なリスクおよび保護要因としての彼らの人種的アイデンティティをテストします。
調査の概要
状態
条件
詳細な説明
人種差別の経験は、少数民族の若者の身体的および精神的健康問題の重大なリスクとなります。 1つの説明は、慢性的なストレスが変化した調節不全のストレス反応につながり、個人が健康上の問題を起こしやすくなる可能性があることを示しています. 現在、微妙な人種差別に対する少数民族の若者のストレス反応を包括的に測定したり、人種差別経験の寄与する役割と考えられるリスクおよび保護要因を調査したりする実験的研究はありません。
11 歳から 14 歳の少数民族の若者 (ラテン系アメリカ人 40 人、黒人/アフリカ系アメリカ人 40 人) とその両親のコミュニティ サンプルが募集されます。 この研究では、若者に広く使用され、白人の仲間からの微妙な人種差別の経験を引き出すように慎重に設計された、適応された仲間の拒絶タスクを採用しています。 青少年の心血管活動と唾液サンプルは、視床下部-下垂体-副腎 (HPA) 軸、自律神経系 (ANS)、および炎症性メディエーター (わたしは)。 青少年は、人種差別の経験を報告し、同僚から拒絶された経験について帰属を示し、人種的アイデンティティを評価します。 両親は、民族的人種社会化の実践を報告するためにアンケートに記入します。
この提案の目標は次のとおりです。1) 人種差別の経験と、微妙な人種差別に対する少数民族の若者のストレス反応との関係を明らかにする。 2) 親の民族的・人種的社会化、微妙な人種差別への子供の帰属、および潜在的なリスクおよび保護要因としての彼らの人種的アイデンティティーをテストします。

実験的: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. |

Attribution About the Peer Rejection for Peer Rejection
時間枠:immediately after the 5-minute peer rejection task ends

participants will complete the questionnaire, Attribution About The Peer Rejection (AATPR) to rate the likelihood of various reasons for the experience of peer rejection using a 7-point scale.
The higher total score for the 4 racial reasons (possible range: 4-28) indicates the higher tendency of making racial attribution about the peer rejection.
