Brief Summary

The purpose of this randomized controlled pilot study is to examine the preliminary effectiveness, feasibility, and potential treatment moderators (i.e., behavioral symptoms and spousal relationship status) of a newly developed intervention for individuals with dementia and their family caregivers that combines elements of the established care consultation (CC) approach with additional counseling modules (CC+C). Outcomes for Veterans with dementia and their family caregivers (e.g., depressive symptoms, care-related burden, quality of life, pleasant events, etc.) will be assessed after 6 months of treatment and again at 12 months.

Detailed Description

Background: Dementia affects over 7% of Veterans age 65 and above seeking care through the Veteran's Health Administration (VHA), amounting to one out of every eleven Veterans in some VISNs. The unique functional and behavioral impairments associated with Alzheimer's or a related dementia (ADRD) contribute substantially to psychological and physical morbidity of family caregivers and high rates of nursing home placement, with 60% of ADRD caregivers rating the emotional stress of caregiving as "high or very high," and over one third reporting depressive symptoms. Although numerous evidence-based interventions have been developed to reduce caregiver burden and improve mental health and functional outcomes of the person with dementia, a recent systematic review noted almost none of these interventions "make it off of the shelf" to be readily available in clinical settings. Care Consultation (CC) has emerged as a rare exception. CC is an evidence-based telephone intervention delivering psychoeducation, care coordination, and resource referrals in diverse areas such as safety and mental and behavioral health support. Yet CC's focus on coaching and support is inadequate for dyads experiencing high levels of distress. A stepped-intervention approach would address the VA's efficiency needs while allowing the flexibility for more resource-intensive additional counseling beyond the established CC framework when warranted by high dyad distress. This CDA-2 proposal would move such a dyadic intervention forward.

Objectives: 1) Manualize the integration of care consultation and counseling components (i.e., the CC+C intervention). CC+C is guided by a rehabilitation recovery-based conceptual model to address the most common high distress targets (e.g., relationship distress, Veteran or caregiver depression, anxiety, or pain) using patient-centered approaches. 2) Evaluate preliminary effectiveness and feasibility of the CC+C Intervention in a randomized controlled pilot study of distressed dyads to compare: a) the established CC intervention, to b) the CC+C intervention on Veteran and caregiver outcomes. 3) Conduct exploratory analyses of the CC+C intervention on Veteran long-term care placement at six and 12 months and examine two key treatment moderators (behavioral symptoms and spousal relationship status) that may impact intervention engagement and response to treatment.

The investigators hypothesize that: 1) Caregivers assigned to CC+C will have greater reductions in caregiver burden at 6 months than those assigned to CC alone. 2) Indicators of relationship strain (i.e., marital distress and/or mutuality) will show greater improvement in CC+C than CC at 6 months. 3) Gains in shared pleasant events, social engagement, and quality of life will be greater in CC+C than in CC alone at 6 months. 4) Participants with dementia in both groups will have reduced depressive symptoms at 6 months. The investigators will also explore the impact of the two interventions on rates of placement in long-term care facilities (such as nursing homes, VA Community Living Centers or other supportive living environments) at 6 and 12 months.

Methods: Ten modules combining successful elements from existing manualized therapies and exercises developed by the investigative team during the CDA1 period will be integrated with CC into a draft CC+C intervention manual. The manual will be finalized with input from the mentoring team and an Expert Advisory Panel for completeness, feasibility, and safety and risk considerations. Next 68 distressed Veterans with dementia and their family caregivers will be recruited and randomized to either the CC+C intervention group or the CC comparison group. Patient, caregiver, and relationship outcomes (e.g., burden, depressive symptoms, anxiety, quality of life, relationship distress) will be measured at baseline, 6 months, and 12 months. Treatment implementation and feasibility data will be collected.

Anticipated Impacts: The goal of this career development study is to acquire the knowledge, skills and experience necessary to successfully compete for an RR\&D Merit Review Award evaluating a randomized controlled trial powered to establish efficacy and test effectiveness of the CC+C intervention. Rehabilitation-focused interventions that maximize functioning are essential for successful non-institutional VA dementia care in the future. Work completed during the CDA2 period will serve as a foundation for a career committed to this goal. The impact of this work will be realized when an efficacious and highly-accessible intervention, such as the telephone-based dyadic intervention being piloted, becomes available for aging Veterans and their families.

Arm && Interventions

Group	Intervention	Description
Care Consultation (CC)	Care Consultation (CC)	Care Consultation (CC): is an established telephone-based, empowerment intervention that uses coaching and emotional support to mobilize family caregivers and individuals with dementia through psychoeducation, resource referral, psychosocial support, and encouragement of informal and formal service use utilization. A computerized clinical tool called the Care Consultation Information System (CCIS) guides the care consultant through a standardized delivery of protocol components. Rather than a strong focus on assessment, this intervention is designed to quickly identify areas of unmet need through brief trigger questions called the "initial assessment" - much like an interview guide - which then immediately shapes development of concrete action plans.
Care Consultation + Counseling (CC+C)	Care Consultation (CC)	Care Consultation + Counseling (CC+C): is consistent with the original CC protocol in that the therapist partners with each dyad in a patient-centered way to prioritize unmet needs as identified during the CC initial assessment. Once this phase has been completed, typically within the first 2 sessions, the CC+C therapist will determine when to initiate counseling sessions targeting 8-10 domains of potential distress (grief, hostility, sexual intimacy, etc.). The counseling component of the CC+C intervention incorporates elements of existing manualized interventions that have been tailored for this population and follow a cognitive behavioral therapy framework.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Caregiver Burden Scores on the Zarit Caregiver Burden Inventory	Baseline, 6 months	The Zarit Caregiver Burden Inventory is a measure of strain related to providing care for someone with dementia. Scores range from 0 to 48 with higher scores indicating more caregiver burden.
Change From Baseline in Relationship Cohesion on the Dyadic Adjustment Scale	Baseline, 6 months	Relationship satisfaction and cohesion measure for spouses and partners in a romantic relationship. Scores range from 0 to 151, and higher scores indicate higher levels of relationship satisfaction. Not all caregivers were in a romantic relationship with the person with dementia, this scale was only administered to dyads who were married or partnered (e.g., adult children caregivers would not have received this measure).
Change From Baseline in Quality of Life on the World Health Organization (WHO) Quality of Life Measure	Baseline, 6 months	Change in shared pleasant events, social engagement, and quality of life is hypothesized to be greater in caregivers assigned to CC+C than in CC alone at 6 months. Scores range from 19 to 95, and higher scores indicate better quality of life.
Change From Baseline Depressive Symptoms on the Cornell Scale for Depression in Dementia	Baseline, 6 months	Depression symptoms measure, scores range from 0 to 38 with higher scores indicating more depressive symptoms as rated by their caregiver.

Secondary Outcome Measures

Name	Time	Method
Number and Percentage of Veterans With Dementia in Long-term Care Facilities as Reported by the Caregivers at 12 Months	12 months	Number and percentage of Veterans with dementia in long-term care facilities as reported by the caregivers at 12 months.
