Socially Isolated Older Adults Living With Dementia

Study Overview
=================
Brief Summary
-----------------
The lack of efficacious research-based interventions for sexual and gender minority (SGM) older adults living with Alzheimer's disease and other dementias, combined with the heightened risk of cognitive impairment in this population, presents a significant public health problem. SGM older adults are at elevated risk of social isolation and experience significant barriers to healthcare access. Existing interventions for older adults with dementia have been found to be effective for caregiving dyads. Yet SGM older adults, compared to heterosexuals, are significantly less likely to be married or to have biological family members to support them. A significant proportion of SGM older adults living with dementia have no caregiver or care network. The goal of the proposed research is to design and pilot test the cultural appropriateness, acceptability, and feasibility of an innovative translation of a personalized care network-RDAD (Reducing Disability in Alzheimer's Disease) to support those living with dementia without a family caregiver, directly addressing unique SGM-specific risk factors.

Detailed Description
-----------------
We will address the following aims: Aim 1. Develop a personalized care network-RDAD intervention suitable for SGM older adults living with dementia without caregivers. Aim 2. Implement a preliminary randomized controlled trial (RCT) of 30 participants with 2 arms (routine medical care vs. the personalized care network-RDAD approach) to assess the acceptability, feasibility, and initial efficacy of the intervention.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Physical Activity | Minutes spent on exercising per week in the past month were calculated from the following two questions: (1) How much time did you spend on exercises (hours per day) on a typical day during the last month; (2) How many days did you spend on exercises during the last month. | Baseline (pre-treatment) and 7 weeks (post-treatment) | 
| Change in Physical Functioning | Physical Functioning subscale of the Medical Outcomes Study 36-Item Short Form (SF-36) consists of 10 items and measures how much participants' health status limits their activities including walking, climbing, lifting, and bathing or dressing oneself, based on self-reports. Each item is measured a 3-point scale (1 = Yes, limited a lot; 2 = Yes, limited a little; 3 = No, not limited at all), then recoded into 0, 50, and 100, respectively. The recoded scores are averaged to generate a summary score with its possible range from 0 to 100. Higher scores indicate better physical functioning. | Baseline (pre-treatment) and 7 weeks (post-treatment) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Quality of Life | Quality of Life in Alzheimer's Disease (QOL-AD) is a 13-item scale that measures participant's self-reported feelings about different aspects of life including energy, mood, living situation, memory, family, friends, ability, and money. Each item has a 4-point response scale (1 = poor; 2 = fair; 3 = good; 4 = excellent). The summary score is a sum of the 13 items with its possible range from 13 to 52. Higher scores indicate higher quality of life. | Baseline (pre-treatment) and 7 weeks (post-treatment) |
