Community-based multisensory environments as preventive public health interventions for mental well-being in older adults: evidence from a large-scale study in China.

Social participation significantly reduced psychological distress among middle-aged and older community-dwelling adults exposed to multisensory environments.

• Study sample consisted of 1,897 community-dwelling adults in China aged 50-69 years
• Participants experienced community-based immersive environments before completing a structured survey
• Structural equation modeling (SEM) was used to test the pathways between social participation, psychological distress, acceptance, and mental health
• Social participation was identified as a critical driver of mental health outcomes in this population

Psychological distress reduction mediated the relationship between social participation and acceptance of immersive multisensory environments.

• Reduced psychological distress was associated with increased acceptance of immersive environments
• Acceptance functioned as 'a proximal mechanism of change' in the pathway to mental health improvement
• The SEM framework revealed a sequential pathway: social participation → reduced psychological distress → acceptance → mental health improvement
• Both social participation and acceptance 'jointly emerged as critical drivers' of mental health outcomes

Acceptance of immersive multisensory environments exerted a significant positive effect on mental health improvement.

• Acceptance was identified as a key intermediate variable linking distress reduction to mental health outcomes
• The effect of acceptance on mental health improvement was statistically significant per SEM results
• This pathway highlights the importance of user acceptance as a mechanism through which environmental interventions operate
• Findings were derived from a large-scale sample of 1,897 participants

Cluster analyses identified distinct psychosocial profiles and sensory preferences among participants, revealing subgroup-specific patterns relevant to intervention design.

• Cluster analysis was conducted on the sample of 1,897 community-dwelling adults
• Multiple distinct psychosocial profiles were identified through the clustering procedure
• Participants also showed distinct sensory preferences across identified clusters
• These subgroup differences offer 'insights into subgroup-specific intervention strategies' for tailoring multisensory environments

Middle-aged and older adults (aged 50-69 years) were identified as particularly vulnerable to early-stage psychological distress due to shifts in social roles and community participation.

• This age group is described as the 'young-old' in the paper
• The study focuses on community-dwelling adults in China navigating social role transitions
• Traditional approaches including pharmacological treatment, counseling, and organized activities were noted to 'lack personalization, scalability, and sustainable engagement'
• The demographic transition in China was cited as bringing mental health of older adults 'to the forefront of public health concerns'

Community-based immersive multisensory environments were proposed as scalable, person-centered, and culturally relevant non-pharmacological interventions complementing existing public mental health strategies.

• The study provides 'large-scale empirical evidence on the behavioral and psychosocial pathways through which multisensory environments support mental health in later life'
• Multisensory environments are positioned as complementary to, rather than replacements for, existing interventions
• The community-based delivery model was emphasized as supporting scalability and cultural relevance
• The intervention model is described as 'person-centered' based on identified subgroup profiles and sensory preferences
