Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A 12-week pilot study was conducted in 8 dementia care facilities involving (n = 83) participants addressing the hypothesis that an intervention increasing indoor exposure to daylight will reduce depression and other neuropsychiatric symptoms. At 4 facilities, staff was enlisted to increase daylight exposure by taking participants to a perimeter room with daylight exposure for socialization in the morning (8:00 - 10:00 AM) each day. At the other 4 facilities, a control group were taken to a similar sized area without daylight for socialization under typical electrical lighting conditions. Outcome measures for depression and other neuropsychiatric symptoms were taken at the beginning and end of the 12-week study.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control
At the 4 facilities in the control arm, participants received the usual care. During the period from 8:00 - 10:00 AM each day, the control group was taken to a similar sized area indoors (without daylight) for socialization under typical electrical lighting conditions.
No interventions assigned to this group
Daylight Intervention
At the 4 facilities in the active light intervention arm, staff increased the daylight exposure of participants by taking them to the perimeter zone of a daylit room from 8:00 to 10:00 AM for socialization over a period of 12 weeks. The perimeter zone was defined to be the region of the room within 3 meters from windows. The intervention was administered each day (7 days / week) over the duration of the study.
