まとめ
不安は,神経発達障害と神経精神疾患における同一性 (IS) と強迫性との関連がある. これらの関連性は 診断グループ全体で一致しており 行動における不安の 診断を超えた役割を強調しています
科学分野:
- 神経科学
- 児童・青少年精神科
- 心理学
背景:
- 同一性 (IS) と強迫性は,様々な神経発達障害 (NDD) と神経精神疾患 (NPD) で観察されています.
- 以前の研究では 主に自閉症や強迫性障害 (OCD) のような 特定の診断カテゴリー内の行動に焦点を当てていました
- NDDとNPDのより広い範囲でISと強迫性の不安の役割は実証的に調査されていません.
研究 の 目的:
- 子供と青少年の大規模なトランス診断サンプルで,不安,IS,および強迫性の間の関連を調べる.
- 不安が様々な診断グループの中で ISや強迫症と関連しているかどうかを判断する.
- ISと強迫性の 診断を超えた性質と これらの行動における不安の役割を確認する
主な方法:
- 自閉症,ADHD,内在化障害,OCD/Tic障害,ODD/CDなどの診断を受けた1852人の子供と青少年 (平均年齢10.36) のトランス診断サンプルを募集した.
- 同一性 (IS) と強迫性は,リピティティブ・ビヘイバー・スケール・リベイスドを用いて評価された.
- 子どもの不安障害のスクリーンを用いて不安を測定した.
主要な成果:
- 診断グループ (自閉症,ADHD,OCD/Tic) の内では,影響の大きさは小さいが,不安はISと少し強い関連を示した.
- 不安,IS,および強迫性との相互関係は,診断グループによって有意に異なるものではありません.
- 自閉症とODD/CDのグループと比較して,ISと強迫性の関連性は少し弱かった.
結論:
- 発見はNDDとNPDの間でISと強迫性のトランス診断的性質を支持します.
- 初期診断とは無関係に不安は ISと強迫性において重要な役割を果たします
- これらの結果は,ISの表れにおける不安と,様々な児童および青少年精神疾患における強迫感を含む共通の基礎的メカニズムを示唆している.
