まとめ
目標設定のみでは認知症リスク軽減行動を改善せず、質の高い食事目標はMIND食事療法への遵守を改善した。
科学分野:
- 神経科学;行動科学;老年学
背景:
- 修正可能な生活習慣因子は、認知症リスクを低減するために重要である。デジタル介入は、行動変容技法(BCT)をますます組み込んでいる。目標設定は、認知症リスク低減(DRR)のための重要なBCTである。
研究 の 目的:
- 主観的認知機能低下(SCD)または軽度認知機能障害(MCI)を有する個人において、デジタル介入における目標設定への関与がDRR行動を予測するかどうかを検討する。目標設定の質とDRR行動変容との関連を評価する。自己主導型と専門家主導型目標設定の効果を比較する。
主な方法:
- MyCOACH試験のSCD/MCIを有する135人の参加者の分析。自己主導型SMART目標の質と専門家主導型目標設定への関与の評価。目標設定、心理学的決定因子、およびベースラインリスクからDRR行動変容を予測する階層的回帰分析。
主要な成果:
- 目標設定への関与のみでは、全体的なDRR行動変容を予測する上で有意ではなかった。ベースライン時の認知症リスクがDRR改善の唯一の有意な予測因子であった。質の高い自己主導型SMART目標は、身体活動ではなく、MIND食事療法への遵守の改善と相関していた。
結論:
- 目標設定のみでは、全体的なDRR行動変容には不十分である。質の高い食事目標は、MIND食事療法への遵守を強化する可能性がある。将来の研究では、多様なDRR行動のためのBCTの組み合わせと改良を探求する必要がある。
