Outcome Measures
Primary Outcomes (1)
Change in Cornell Scale for Depression in Dementia (CSDD)
The Cornell Scale for Depression in Dementia (CSDD) was used to measure depression. The CSDD is designed for the assessment of depression in older people with dementia who can at least communicate basic needs. The CSDD scale ranges from 0 to 38, with higher scores indicating higher levels of depression. Scores above 10 indicate a probable major depression. Scores above 18 indicate a definite major depression. Scores below 6 are associated with absence of significant depressive symptoms.
A CSDD score was taken at the beginning of the 12-week study and once again at the end of the 12-week study.
Secondary Outcomes (1)
Change in Neuropsychiatric Inventory Nursing Home Version (NPI-NH)
A NPI-NH score was taken at the beginning of the 12-week study and once again at the end of the 12-week study.
Study Arms (2)
Control
NO INTERVENTIONAt 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.
Daylight Intervention
ACTIVE COMPARATORAt 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.
Interventions
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.
Eligibility Criteria
You may not qualify if:
- physical co-morbidities that precluded participation in the daily group intervention

Limitations and Caveats
Scheduling problems with baseline measures led to CSDD scores from health records being used for some participants with scoring dates that predated the start of the study by up to 4 months.
