まとめ
インターネットベース認知行動療法(ICBT)は、ブラジルにおける強迫性障害(OCD)の効果的な治療法でした。このプログラムは、症状の大幅な軽減と寛解率を示し、より広範な実施の実現可能性を示唆しています。
科学分野:
- メンタルヘルス;精神医学;デジタルヘルス
背景:
- 強迫性障害(OCD)は、世界的に重大なメンタルヘルス上の課題です。認知行動療法(CBT)のようなエビデンスに基づいた治療へのアクセスは、特定の地域では限られている可能性があります。インターネットベースのCBT(ICBT)は、治療ギャップを埋めるためのスケーラブルなソリューションを提供します。
研究 の 目的:
- ブラジル、サンパウロで開発されたスウェーデン製のOCD向けICBTプログラムの実施と有効性を評価すること。OCD-NET治療マニュアルをブラジルの文脈に合わせて適応および翻訳すること。RE-AIMフレームワークを使用して治療結果を評価すること。
主な方法:
- OCDと診断された35人の成人を対象としたオープンラベル試験。曝露反応妨害(EPR)に基づいた10モジュールのICBTプログラムの提供。RE-AIMフレームワーク、強迫性障害の重症度を評価するためのイェール・ブラウン強迫性障害尺度(Y-BOCS)、およびうつ病の症状を評価するためのPHQ-9を使用した評価。
主要な成果:
- 参加者の85.7%がプロトコルを完了し、35人中30人がICBTプロトコルを完了しました。強迫性障害の重症度は大幅に減少し、60%が治療反応を示し、30%が6ヶ月の追跡調査で寛解しました。うつ病の症状(PHQ-9スコア)の改善が観察されました。
結論:
- ICBTは、中高所得国の文脈において、OCDの実現可能かつ効果的な治療法です。適応されたOCD-NETプログラムは、より広範な実施に有望です。十分なサービスを受けていない集団におけるICBTの受容性をさらに調査する必要があります。
