Wayfinding
More than 66% of residents with severe dementia have difficulties with wayfinding (Passini et al., 2000)
Poor wayfinding abilities influence:
Safety risks for resident that wanders (Rosswurm, Zimmerman, Schwartz-‐Fulton, & Norman, 1986)
Conflict with other residents (Rosswurmet al.)
Burden to nursing home staff (Everitt, Fields, Soumerai, & Avorn, 1991)
Previous Research
Combination text + photo stimulus hung outside bedroom improved room finding for older adults with dementiaUnclear what aspects of stimulus were
responsible for the change(Nolan, Mathews, & Harrison 2001)
Printed names recognized marginally more than current pictures (Gross et al., 1994)
JOE SHMOE
Previous ResearchBetter recognition of younger photos compared to older photos (Hehman, German, & Klein, 2005)
Recognition of photographs was not enough to produce room finding improvement when photographs were removed between observationsSuggests that recognition of items is not enough to facilitate room finding when controlling for naturally occurring learning trials
(Jay, Feliciano, Anderson & LeBlanc, 2009)
Purpose of the Study
Determine whether personal relevance and recognition of memory box items is necessary to improve room finding
Method
1. Stimulus Recognition Assessment
2. Family Interview & Stimulus Preference Assessment
3. Room Finding Analysis
ParticipantsN = 14 older adults
Mean Age = 86 yrs (range 79 to 93)
13 females, 1 male
Mean MMSE = 9 (range 1 to 19)
SettingMemory care communities in Michigan and Colorado
Experiment 1: Stimulus Recognition Assessment
Opportunity to choose self out of an array of 3 choicesFour stimulus groupsYoung adult photograph (20-‐40 yrs old)Middle adult photograph (40-‐60 yrs old)Current photograph Printed name
Experiment 1: Stimulus Recognition AssessmentAccuracy of selection recorded
No feedback provided on accuracy
6 trials of each stimulus type = 24 trials
Stimuli counterbalanced to prevent selection based on side bias
Order of stimulus type counterbalanced to prevent order effects
Experiment 2: Stimulus Preference Assessment
Paired stimulus preference assessment procedureItems selected based on Semi-‐structured family interviewPleasant Events Schedule Disease (PES-‐AD)
3 preferred items, 3 non-‐preferred itemsHierarchy of relative preference used to design memory boxes
