Telephone Acceptance and Commitment Therapy Intervention for Caregivers of Adults With Dementia (TACTICs)

July 23, 2022 updated by: Shelley Johns, Indiana University

Telephone Acceptance and Commitment Therapy Intervention for Caregivers of Adults With Alzheimer's Disease and Related Dementias (TACTICs): A Pilot Randomized Controlled Trial

Caregivers of adults with dementia report higher distress, including anxiety and depressive symptoms, burden, and existential suffering, than caregivers of people with other chronic diseases. Acceptance and Commitment Therapy (ACT) is a behavioral intervention designed to increase psychological flexibility in the face of challenges. Results from our recent proof-of-concept study suggest that ACT is effective in reducing anxiety and associated psychological distress in dementia caregivers. In this study, we will randomize N=60 dementia caregivers in equal numbers to receive either 6 weekly 1-hour telephone-based ACT sessions (TACTICs; experimental) or minimally-enhanced usual care (mEUC; control). We hypothesize that our TACTICs intervention will be feasible and acceptable in this population and will have a greater impact on reducing anxiety and secondary outcomes from baseline to post-intervention, and 3 and 6 months later.

Detailed Description

The objective of this pilot randomized controlled trial is to assess feasibility, acceptability, and preliminary effects of Telephone Acceptance and Commitment Therapy Intervention for Caregivers (TACTICs) of adults with Alzheimer's disease or related dementias. Using a 2-arm randomized design, we will examine the effects of TACTICs compared to a minimally enhanced usual care group (mEUC) in N=60 dementia caregivers. Primary dementia caregivers with clinically-significant anxiety will be randomized in equal numbers to receive either TACTICs or mEUC. The specific aims are to: (1) Evaluate the feasibility and acceptability of TACTICs. Feasibility will be assessed using caregiver accrual, retention, and TACTICs session attendance rates. Acceptability will be assessed using a participant-reported satisfaction item administered upon intervention completion. (2) Measure the changes in caregiver anxiety and depressive symptoms, caregiver burden, wellbeing, and psychological flexibility at post-intervention (T2) and 3 months (T3) and 6 months (T4) post-intervention compared to baseline. Caregivers will be recruited from a variety of sources, including the Indiana Alzheimer's Disease Center (IADC), Aging Brain Care program at Eskenazi Health, and Indiana University Health geriatric psychiatry and neurology practices. Study staff will contact potentially-eligible caregivers to assess interest and verify eligibility. After providing informed consent and enrolling in the trial, interested and eligible caregivers will complete baseline measures and be randomly assigned in equal numbers to either the TACTICs intervention (n=30) or to mEUC (n=30) using a block randomization scheme. Randomization will be performed in REDCap using a SAS procedure. All study personnel will be blind to allocation sequence. The unblinded research coordinator will be responsible for randomizing participants in REDCap. The PI, Co-Investigators, and research assistants (i.e., recruiters and outcome assessors) will be blind to intervention assignment to reduce the risk of outcome expectancy bias and to enhance the rigor of the trial.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Baseline Anxiety via Generalized Anxiety Disorder scale-7 (GAD-7)
Time Frame: baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Changes in anxiety will be measured using the Generalized Anxiety Disorder Scale (GAD-7), which contains 7 items with total scores ranging from 0 to 21. Scores of 5, 10, and 15 are cut-offs for mild, moderate, and severe anxiety, respectively. An add-on item assessing the patient's global impression of symptom-related impairment helps researchers understand the extent to which anxiety interferes in daily life. The GAD-7 has factorial validity for the diagnosis of general anxiety disorder and is sensitive to change.
baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Baseline Depressive Symptoms via Patient Health Questionnaire-9 (PHQ-9)
Time Frame: baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Changes in depressive symptoms will be measured using the 9-item Patient Health Questionnaire-9 (PHQ-9) to assess depressive symptoms. With total scores ranging from 0 to 27, scores of 5, 10, 15, and 20 represent mild, moderate, moderately severe, and severe depression, respectively. The PHQ-9 has factorial validity for the diagnosis of major depressive disorder.
baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Change in Baseline Caregiver Burden via Zarit Burden Interview (ZBI)
Time Frame: baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Changes in caregiver burden will be measured using the Zarit Burden Interview (ZBI). This two-factor, 22-item scale measures personal strain and role strain in caregiving by summing responses to a total score (0-20 little or no burden; 21-40 mild to moderate burden; 41-60 moderate to severe burden; and 61-88 severe burden). The ZBI measures change over time resulting from the progression of the patient's symptoms or from interventions aimed at reducing burden.
baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Change in Baseline Wellbeing via Experience of Suffering Scale (ESS)
Time Frame: baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Changes in wellbeing will be measured using the Experience of Suffering Scale (ESS). With prior testing in ADRD caregivers, the ESS contains 33 items across 3 subscales: physical (9 items), psychological (15 items), and existential (9 items) suffering. Total scores for each subscale are calculated with higher scores indicating more suffering within each domain.
baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Change in Baseline Coping via Brief COPE
Time Frame: baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Changes in coping will be measured with the 28-item Brief COPE, a measure of coping strategies used in response to stressors. Comprised of 28 coping strategies, the Brief COPE contains 14 two-item subscales, each analyzed separately: self-distraction, active coping, denial, substance use, use of emotional support, use of instrumental support, venting, behavioral disengagement, positive reframing, planning, humor, acceptance, religion, and self-blame.
baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Change in Baseline Psychological Flexibility via Acceptance and Action Questionnaire-II (AAQ-II)
Time Frame: baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Changes in psychological flexibility and its opposite, experiential avoidance, will be measured using the 7-item Acceptance and Action Questionnaire-II (AAQ-II). Respondents rate how true each statement (e.g., "It is okay if I remember something unpleasant") is for them on a 7-point Likert-type scale anchored from 1=never true to 7=always true. Higher scores indicate greater psychological flexibility or acceptance.
baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Change in Baseline Quality of Life via PROMIS Global Health measure
Time Frame: baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Changes in quality of life will be assessed with the 10-item PROMIS Global Health measure. On a 5-point scale, participants rate their mental and physical well-being with higher scores indicative of better health.
baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Change in Baseline Anticipatory Grief via Anticipatory Grief Scale (AGS)
Time Frame: baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention
Changes in anticipatory grief will be measured with the Anticipatory Grief Scale (AGS), a 27-item self-report tool designed to assess the bereavement experience of dementia caregivers. Items are scored on a 5-point Likert scale with responses ranging from "strongly disagree" to "strongly agree."
baseline, post-intervention (7-9 weeks post-baseline), 3 months post-intervention, 6 months post-intervention

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Intervention feasibility: accrual rate
Time Frame: baseline
We will assess the number of eligibly-screened caregivers who choose to consent and enroll in the trial. This accrual outcome speaks to intervention feasibility.
baseline
Intervention feasibility: attendance rate
Time Frame: post-intervention
We will assess the total number of sessions that participants allocated to TACTICs attend (i.e., out of 6 sessions possible). This attendance outcome speaks to intervention feasibility.
post-intervention
Intervention feasibility: retention rate
Time Frame: 6 months post-intervention
We will assess the number of enrolled subjects completing the final outcome assessment at 6 months post-intervention. This retention outcome speaks to intervention feasibility.
6 months post-intervention
Intervention acceptability
Time Frame: post-intervention
We will assess intervention acceptability using a brief investigator-created battery of quantitative and qualitative satisfaction items.
post-intervention
Health care and resource utilization
Time Frame: baseline, post-intervention, 3 months post-intervention, 6 months post-intervention
Health care and resource utilization will be measured using an investigator-created battery of items. Items will assess caregiver-reported health and mental care utilization (e.g., ED, inpatient, outpatient) and services accessed or used to support their caregiving (e.g., support groups, respite care, in-home aid).
