About this trial

This pilot randomized controlled trial evaluates the feasibility and preliminary efficacy of VICA, an AI-powered virtual care assistant that delivers evidence-based education, symptom monitoring, and coaching to informal caregivers of people living with Alzheimer's disease and related dementias (ADRD). Sixty caregiver-patient dyads will be randomized 1:1 to VICA or an attention-control education app (Dementia Guide Expert) for 3 months. The study will assess recruitment, VICA acceptance/usability, and engagement (Aim 1), and estimate effect sizes for reducing patient behavioral and psychological symptoms of dementia (BPSD) and caregiver distress (Aim 2).

Treatments tested in this trial

  • VICA - Virtual Informal Care Assistant

    Device

    An AI-powered avatar delivering conversational, speech-to-speech and text-based education, resource information, and symptom-monitoring support to informal caregivers of patients with Alzheimer's disease and related dementias (ADRD), grounded in the ABC collaborative dementia care model via a retrieval-augmented generation system.

  • Education only BPSD mobile app

    Device

    Access to Dementia Guide Expert, an existing free, education-only BPSD mobile app (ENGAGE-IL initiative, University of Illinois at Chicago), used on the same 3x/week, \~20 minute schedule for 3 months. No interactive coaching, assessment, or personalized response.

Trial outcomes

Primary outcomes

1

Neuropsychiatric Inventory (NPI) total score

A 12-domain caregiver-informant-rated measure of patient behavioral and psychological symptoms of dementia. Each domain is scored as frequency (1-4) times severity (1-3) if present, or 0 if absent. Domain scores are summed for a Total Score ranging 0-144; higher scores indicate more frequent and/or severe symptoms.

Time frame
Baseline, 1, 2, and 3 months
2

Neuropsychiatric Inventory-Distress (NPI-D) Scale

Derived from the same 12-domain NPI interview. For each domain in which a symptom is present, the caregiver rates how emotionally distressing that behavior is to them, from 0 (not at all) to 5 (very severely). Ratings are summed across domains for a total score of 0-60; higher scores indicate greater caregiver distress.

Time frame
Baseline, 1, 2, and 3 months
3

Assessment completion rate

Time frame
Computed at 3 months
4

Recruitment rate

Recruitment rate computed monthly as # approached, # agreeing, and \# consenting, tracked continuously throughout the accrual period.

Time frame
up to 15 months

Secondary outcomes

1

Patient Health Questionnaire-9 (PHQ-9)

A 9-item caregiver-reported measure of depressive symptom severity. Scored 0-27; higher scores indicate more severe depression.

Time frame
Baseline, 1, 2, and 3 months
2

Generalized Anxiety Disorder 7-item Scale (GAD-7)

A 7-item caregiver self-report measure of anxiety symptom severity, scored 0-3 per item and summed for a total ranging 0-21; higher scores indicate more severe anxiety.

Time frame
Baseline, 1, 2, and 3 months
