「表情解析に基づくSOLO感情指数Well-beingとQOSとの関連性の検証－要介護高齢者及び認知症高齢者を対象とした介入調査を通して－」において科学的な評価が求められる福祉分野において、表情が生活の質（Quality of Life；QOL）を検討する要因と成り得ることを示唆しています。
要旨
認知症は中重度になると生活の質（Quality of Life；QOL）の評価が難しくなります。睡眠の質（Quality of Sleep；QOS）はQOLに関連する報告があり，表情による認知症判定や感情分析の研究も進んでいます。本研究では，認知症高齢者の表情からRussell円環モデルに基づき表情解析するSOLO感情指数の有用性を検証し，SOLOデジタルセラピーの介入効果を検討しました。
本研究をとおして認知症高齢者のQOS評価はSOLO感情指数が有用であることを示しました。QOLに影響を及ぼす活動量・周期性体動指数・Well-beingとの関連を示し，QOSとQOLの関連を示す先行研究を裏付けました。

Introduction: When dementia is moderately severe, it is difficult to evaluate Quality of Life (QOL). Studies show a relationship between Quality of Sleep (QOS) and QOL, and research on dementia evaluation and emotional analysis using facial expressions is progressing. This study examined the usefulness of the SOLO emotion index, which analyzes facial expressions based on the Russell cyclic model, and considered the intervention effects of SOLO digital therapy.
Method: We investigated the relationship between the SOLO emotional index and QOS in 52 institutionalized residents and examined the amount of effect the intervention had on sleep efficiency. QOS was evaluated with a sheet-type body vibration meter (NEMURI SCAN).
Results: Relationships between the Energy and Valence evaluation axes of the Russell cyclic model and sleep duration and sleep efficiency, which indicate QOS, were shown, suggesting a relationship between the SOLO emotional quotient and QOS. It was shown that the activity volume and periodic body movement indexes are positively related to Valence and Well-being. When the effect of SOLO digital therapy intervention on sleep efficiency was examined, it was suggested that it would affect Energy and Valence in elderly people with dementia who can do some things independently.
Conclusion: The QOS evaluation of elderly people with dementia showed that the SOLO sentiment index is useful. The relationship between activity volume, periodic body movement index, and well-being affecting QOL was shown, and prior research showing the relationship between QOS and QOL was supported.
