Learning and Improving Alzheimer's Patient-Caregiver Relationships Via Smart Healthcare Technology
April 19, 2023 updated by: Karen Rose, Ohio State University
Collaborative Research: Learning and Improving Alzheimer's Patient-Caregiver Relationships Via Smart Healthcare Technology
The purpose of this project is to develop a monitoring, modeling, and interactive recommendation solution (for caregivers) for in-home dementia patient care that focuses on caregiver-patient relationships.
This includes monitoring for mood and stress and analyzing the significance of monitoring those attributes to dementia patient care and subsequent behavior dynamics between the patient and caregiver.
In addition, novel and adaptive behavioral suggestions at the right moments aims at helping improve familial interactions related to caregiving, which over time should ameliorate the stressful effects of the patient's illness and reduce strain on caregivers.
The technical solution consists of a core set of statistical learning based techniques for automated generation of specialized modules required by in-home dementia patient care.
There are three main technical components in the solution.
The first obtains textual content and prosody from voice and uses advanced machine learning techniques to create classification models.
This approach not only monitors patients' behavior, but also caregivers', and infers the underlying dynamics of their interactions, such as changes in mood and stress.
The second is the automated creation of classifiers and inference modules tailored to the particular patients and dementia conditions (such as different stages of dementia).
The third is an adaptive recommendation system that closes the loop of an in-home behavior monitoring system.

Experimental: Dementia/Caregiver Dyad
All dementia/caregiver dyads will have in-home acoustic monitoring to classify mood and will be provided mindfulness-based stress reduction recommendations via a smart phone.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Acoustic Monitoring/Mood Classifier
Time Frame: Through study completion, average of 4 months
|
The acoustic monitoring will occur for 1 month to establish baseline interactions between the family caregiver and the persons with dementia.
Acoustic monitoring and text message recommendations will occur over the subsequent 3 months.
|
Through study completion, average of 4 months
|
Change in Caregiver Depression, Anxiety and Stress
Time Frame: Baseline, 4 months
|
Depression Anxiety Stress Scale (DASS): The DASS is a set of three self-report scales designed to measure the negative emotional states of depression, anxiety and stress.
The DASS was constructed not merely as another set of scales to measure conventionally defined emotional states, but to further the process of defining, understanding, and measuring the ubiquitous and clinically significant emotional states usually described as depression, anxiety and stress.
As the scales of the DASS have been shown to have high internal consistency and to yield meaningful discriminations in a variety of settings, the scales should meet the needs of both researchers and clinicians who wish to measure current state or change in state over time (e.g., in the course of treatment) on the three dimensions of depression, anxiety and stress.
Minimum score: 0; Maximum score: 168; A higher score indicates higher levels of depression, anxiety and stress.
|
Baseline, 4 months
|
Change in Caregiver reaction to dementia behaviors
Time Frame: Baseline, 4 months
|
The Revised Memory and Behavior Problems Checklist (RMBPC) is a 24-item, caregiver-report measure of observable behavioral problems in dementia patients and the caregiver's stress reactions to these behavioral disturbances.
The instrument provides a total score and 3 subscale scores for patient behavioral problems (memory-related, depression, and disruptive behaviors) and corresponding scores for caregiver reactions to each of these.
Overall scale internal consistency of the instrument is reported as .84
for patient behavior and .90 for caregiver reaction and the instrument has confirmed validity through comparison of instrument scores with measures of depression, cognitive impairment, and caregiver burden Minimum score: 0; Maximum score: 120.
A higher score indicates higher levels of caregiver reaction to dementia behaviors.
|
Baseline, 4 months
|
Change in caregiver emotional reactivity
Time Frame: Baseline, 4 months
|
The 16-item, Difficulties in Emotion Regulation Scale (DERS-16) will be used to measure caregivers' ability to regulate emotions at baseline and end of study.
The scale used is the brief version of a theoretically-driven, valid, and reliable self-report tool used to measure difficulties with emotion regulation.
The brief version will be more easily administered with the study population and has been shown to be valid and reliable [41].
Minimum score: 16; Maximum score: 80.
A higher score indicates higher levels of caregiver emotional reactivity.
|
Baseline, 4 months
|
Change in caregiver capacity for mindfulness practice
Time Frame: Baseline, 4 months
|
Caregivers will be asked to complete the 39-item Five Facet Mindfulness Questionnaire to measure their capacity for five different domains of mindfulness practice at baseline and end of study.
The five facets include non-reactivity to the inner experience, non-judgment of the inner experience, acting with awareness, observing, and describing internal states.
The questionnaire has good reliability and validity Minimum score: 39; Maximum score: 195.
A higher score indicates higher levels of caregiver capacity for mindfulness practices.
|
Baseline, 4 months
|
Change in Caregiver Strain
Time Frame: Baseline, 4 months
|
Modified Caregiver Strain Index (MCSI): It is a 13-item self-report measure that examines both subjective and objective elements of caregiver strain.
The MCSI showed excellent inter-item and test-retest reliability and was correlated in expected directions with relevant criteria [32].
It has excellent reliability and validity, displays adequate clinical sensitivity, has an established cut-off for determining functional/dysfunctional systems, and has been used successfully on a variety of mental health outcomes [28].
We will use a practice tracking worksheet to assess how much the caregivers practice the exercises over the course of the study.
Minimum score: 0; Maximum score: 26.
High scores indicates higher caregiver strain.
|
Baseline, 4 months
|
Change in Family Functioning
Time Frame: Baseline, 4 months
|
Family Assessment Device (FAD): The FAD is a self-report measure that is given as a set of seven subscales of varied length.
Each subscale measures a different dimension of family function.
Scores for each dimension (problem solving, communication, roles, affective responsiveness, affective involvement, behavior control, and general functioning) are calculated separately as the mean of the items in that subscale.
The information obtained through the FAD allows for the elucidation of the structure and organization of the family system, as well as the identification of common patterns of interaction among family members.
The FAD is heavily used in research related to the function of family systems, and it has demonstrated excellent validity and reliability in both non-clinical and clinical populations.
Minimum score:0 ; Maximum score: 212.
A higher score indicates greater levels of family functioning.
