まとめ
子供の頃のトラウマは 統合失調症 (PLS) の患者で 攻撃性の高まりと 感情の認識能力の低下に関連しています しかし 感情の認識は この南アフリカの研究で 攻撃性を直接予測できませんでした
科学分野:
- 精神科
- 神経科学
- 社会科学
背景:
- 統合失調症 (PLS) を患っている人は 暴力的行為や 被害者の割合が高くなります
- 社会的認知の欠陥,特に感情の認識は,PLSの攻撃性に関連しています.
- 子どもの頃のトラウマは 統合失調症や攻撃性の重要な危険因子であり 認知障害と関連しています
研究 の 目的:
- 南アフリカのホサ族の統合失調症 (PLS) 患者における子供のトラウマ,社会的認知 (感情の認識) と生涯の攻撃性との関係を調査する.
- 社会経済的な要因の影響と 低所得や中所得層における暴力への曝露を考慮し,大規模なサンプルでこれらの関連を調べる.
主な方法:
- 南アフリカのホサ族の研究における統合失調症のゲノミクスのサブサンプルは使用された (585 PLS, 882 コントロール).
- 参加者は子供時代のトラウマアンケート (CTQ),ペン・エモーション・識別テスト (ER),アグレッション・アンケート (LHA) を記入した.
- グループ差は,tテストとチ2テストを用いて評価され,多変量線形回帰ではCTQ,ER,LHAの関連性が評価された.
主要な成果:
- PLSは子供の頃のトラウマと生涯の攻撃性,そして感情の認識がコントロールと比較して著しく高いことを報告しました.
- 子供の頃のトラウマのスコアが高くなり 生涯にわたる攻撃性と 感情の認識能力の低下が関連していました
- 感情の認識能力は 生涯の攻撃性とは直接関係がないことが分かりました
結論:
- 子どもの頃のトラウマは 生涯に渡る攻撃性と 統合失調症患者の感情認識障害の 重要な予測因子です
- 子供の頃のトラウマは 攻撃性と感情認識の両方に影響を及ぼしますが 感情認識能力自体は この文脈で攻撃性の直接的な仲介者ではないようです

These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.

Socioemotional Development during Infancy
115
Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
