まとめ
デジタル脳機能スクリーニング(DBFS)は、軽度認知障害の検出においてMoCAと比較して、強力な構成概念妥当性と高い再検査信頼性を示す。これにより、DBFSは認知機能低下のモニタリングのための信頼できるツールとして確立される。
科学分野:
- 神経科学;医療技術;認知科学
背景:
- デジタル脳機能スクリーニング(DBFS)は、軽度認知障害(MCI)の早期検出とモニタリングのためのデジタルツールである。;MoCAと比較可能であるものの、DBFSは構成概念妥当性と再検査信頼性の正式な検証を欠いていた。;本研究は、DBFSのこれらの心理測定学的特性を確立することを目的とした。
研究 の 目的:
- MoCAに対するDBFSの構成概念妥当性を評価すること。;DBFSの再検査信頼性を評価すること。;DBFSを認知評価のための妥当かつ信頼性の高いツールとして確認すること。
主な方法:
- 157人の参加者(年齢10〜81歳)がDBFSおよびMoCA評価を受けた。;36人の参加者が、中央値305日の間隔で2回目のDBFS評価を完了した。;構成概念妥当性と再検査信頼性は、年齢、性別、教育を考慮した部分Spearman順位相関係数を用いて分析された。
主要な成果:
- DBFS総得点はMoCA総得点と有意に相関した(p < 0.001)。;対応するDBFSとMoCAのドメイン間には強い正の相関が見られた(p < 0.05)これは良好な構成概念妥当性を示唆する。;DBFSの再検査信頼性は高く、Spearmanのρ = 0.65(p < 0.001)であった。
結論:
- DBFSは意図された認知構成概念を効果的に測定し、時間の経過とともに高い信頼性を示す。;本研究の結果は、DBFSを早期認知障害の検出とモニタリングのための実用的でスケーラブルかつ効率的なツールとして検証する。;DBFSは、認知スクリーニングのために多様なヘルスケア設定で展開するのに適している。

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
