Person-Environment Fit for Persons With Dementia

Criterion-referenced interview of patient performance with caregiver The COPM is a reliable and validated measure of performance in primary daily activities (self-care, leisure, productivity) with dyad-caregiver rated of performance and satisfaction. Scores are determined on a likert scale of 1-10 with 1 being lowest and 10 indicating highest of the topic of the question.

The primary outcome analysis is the feasibility of implementation as measured by caregiver satisfaction. The Canadian Occupational Performance Measure will measure caregiver satisfaction of patient performance, high scores indicate higher levels of satisfaction. Range 0-10.

22-item survey, caregiver rates self-perceived level of burden on 5-point Likert scale. The social context of the person with ADRD will be described through analysis of caregiver demographics and rate of caregiver burden measured. Higher scores indicate greater burden. Range of 0-88 points. A score of 17 or more was considered high burden.

The NPI-Q is commonly used as an assessment of behavioral and psychiatric symptoms of dementia in older adults diagnosed with mild cognitive impairment or dementia, internationally, with high reliability and validity. Assessment includes 12 behavioral and psychiatric domains which are rated by caregiver as present or absent (yes/no). Caregivers further rate severity of present behavioral domains. The severity score is summed to yield a total as a measure of BPSD burden. Higher scores indicate higher levels of behavior symptom severity and/or distress. Range 0-36

Criterion-referenced survey completed by caregiver. The FBP has been established as a reliable and valid measure of task performance, social interaction, and problem solving with adults with ADRD. Item responses range from 0 to 4, with higher scores indicating better performance (maximum score 108).

35-item survey completed by caregiver regarding home environment. Allows the caregiver to systematically assess the home environment including accessibility, sanitation, food storage, safety, and sensorial stimulation. Scores range 0-105 with higher scores indicating worse outcomes.

Norm-referenced, 60-item survey completed by caregiver. The caregiver will complete the Adult Sensory Profile as proxy for person with ADRD. This is a valid and reliable 60-question assessment to determine sensory simulation preference and neurological ability for processing sensory simulation. This assessment is not based on a range of scores but normative values. Results can be more than or less than normative values.

The Clinical Dementia Rating (CDR) sum of boxes, a valid and reliable measure, will determine severity of cognitive impairment. Six cognitive domains are assessed in CDR (memory, orientation, judgement and problem solving, community affairs, home and hobbies, and personal care) with feedback from patient performance and caregiver result, and results are scored by a trained professional. Range 0-18, higher scores indicate higher levels of cognitive impairment.

Empatica wearable wrist device Assessment of stress-related biomarkers will measure heart rate variability in beats per minute.

Empatica wearable wrist device Assessment of stress-related biomarkers will measure electrical conductance at the surface of the skin. Skin conductance is measured in units of microsiemens, with normal human EDA ranging from 1 to 20 microsiemens.
