Acceptance Commitment Therapy for Caregivers of People with Memory Loss

Brief Online Acceptance Commitment Therapy for Caregivers: a Fully Longitudinal Mixed Methods RC

Family caregivers for persons with dementia report high levels of depression, stress, and burden. Caregivers' limited time, transportation constraints, and unpredictable schedules make on-line, self-guided interventions more accessible and scalable. Acceptance and Commitment Therapy (ACT) is an established and effective in-person therapy, well-suited to the dementia care giving context where caregivers cannot minimize stress exposure, and report difficult thoughts and emotions. ACT for Caregivers is an on-line self-guided ACT intervention that showed effectiveness in a Stage I pilot (n=52) with participants reporting decreased depressive symptoms, stressful reactions to caring, and caregiver burden, and increased quality of life and positive aspects of caring (all p <.05). Learning from the pilot, the current Stage III intervention will shorten the program from 10 sessions to 6 sessions. The investigators introduce a wait list randomized control trial (RCT) design with fully longitudinal mixed methods to evaluate ACT for Caregivers. Data will be collected at pretest, post-test, and 6-weeks follow-up. Study aims are: 1) to evaluate ACT for Caregivers in a larger sample using an RCT, 2) to understand user experiences and the process of change by collecting short response data from all participants at all time points and interviewing a subset of participants in-depth at two time points, 3) to integrate quantitative and qualitative findings and examine areas of convergence and divergence. This project offers a promising prevention and intervention program to support family caregivers that is scalable, at low cost and with high impact.

Detailed Description

Literature Review An estimated 6.2 million Americans live with Alzheimer's disease or a related dementia (ADRD), and over 11 million family caregivers currently assist a person with ADRD. The combination of cognitive impairment, behavioral symptoms, and loss of a reciprocal relationship can be very challenging for caregivers. Chronic stress can affect caregivers' mental and physical health, and sometimes lead to lower quality of care for the person with ADRD. Research indicates promising pathways to support caregiver mental health through interventions that address coping skills, self-care, and commitment to personal values.

A growing number of studies demonstrate that Acceptance and Commitment Therapy (ACT) is effective in reducing distress across a broad number of conditions and contexts. ACT combines the skills of acceptance, cognitive defusion, being present, self as context, values, and committed action to help individuals engage with a meaningful life. ACT helps individuals feel less guided by rigid or critical thoughts, and it teaches individuals to be nonjudgmental and present when difficult experiences arise. A goal of ACT is to help people develop psychological flexibility, meaning being capable of experiencing and living with difficult thoughts and emotions, while still pursue what matters to the individual.

Caregivers of persons with ADRD often disconnect from meaningful activities and relationships due to the ongoing supervision needed for their loved one. Caregivers experience feelings of grief and loss, even while their loved one is still alive, and sometimes use avoidant approaches to minimize feelings of loss, guilt, and exhaustion. ACT with a therapist is highly effective in helping family caregivers of persons with ADRD to reduce depression, anxiety, and experiential avoidance.

While ACT is traditionally delivered in person with a trained therapist, it has also demonstrated effective psychological and emotional benefits in an online format. Online interventions are well-suited for dementia caregivers, who have limited time, transportation constraints, and unpredictable care schedules. Online programs can be accessed conveniently around care routines, do not require driving or finding supervision for the care receiver, are low-cost for users and providers, and are able to relay informational, emotional, and task-specific support, even to hard-to-reach populations, such as those living in rural areas. Clinical trials indicate that online therapy is effective, arguably equally effective to face-to-face therapy.

The Current Study In 2021, USU researchers published results of a pilot study for an online, self-guided ACT for Caregivers of persons with ADRD. Participation in this 10-session online intervention was associated with decreased depressive symptoms, care-related burden, and stress reactions to behavioral symptoms. Caregivers also reported increased positive aspects of caregiving and quality of life. Importantly, the pilot study lacked a control condition. There is also increasing evidence that ACT, can be delivered more concisely; ACT research in other populations suggests a brief approach may be equally effective as longer programs. Given the time constraints of this population, shorter programs may be more appealing for users. The primary aim of the current project is to use a randomized waitlist controlled trial design to determine whether a shorter six session ACT intervention is effective in improving relevant caregiver outcomes.

While the 2021 pilot demonstrated that ACT could improve caregivers outcomes, the investigators were unable to examine the specific ways that participants utilized ACT in their lives. In other words, currently the field recognizes that individuals can change, but knows less about the mechanisms of change, which is important in moving these interventions forward, and on a larger scale. A mixed methods design will allow for the examination of this project's second aim to integrate participants' quantitative data with descriptions of their lived experience to better understand how the intervention promotes positive change.

Research Objectives The current study uses a randomized wait-list controlled trial design and fully longitudinal mixed methods analysis to examine the effectiveness of a condensed online ACT for Caregivers program.

Aim 1: Empirically evaluate the effectiveness of a six-session online ACT intervention in reducing negative aspects of caregiving (depressive symptoms, burden, stressful reactions to memory and behavior problems) and promotion of positive thoughts and behaviors (recognition of positive aspects of caregiving, improved sleep quality, and increased quality of life).

Aim 2: Qualitatively explore caregivers' lived experience with the intervention and ways that caregivers are applying the skills in their lives and examine the extent to which caregivers' descriptions align with and expand on theory-based mechanisms of change.

Impact

Anticipated Outcomes

The anticipated outcomes of our study are:

1. to improve wellbeing of 100 family caregivers for persons with ADRD via an online, self- guided intervention
2. to complete a Stage III study with sufficient methodological rigor to provide evidence of program effectiveness and justify more widespread implementation of this program.
3. to produce necessary documentation of effectiveness to support pursuit of further funding through the National Institute of Health (NIH) or the National Institute of Mental Health (NIMH). NIH expects to spend 3.4+ billion in ADRD grants in the next year.
4. to understand how caregivers' experience changes over time within and following an intervention
5. to understand how ACT-based skills act as potential drivers of change for family caregivers.

Implications Our study is a robust Stage III test of the effectiveness of a shorter (more user-friendly) version of ACT for Caregivers, which has not yet been empirically tested using a randomized control design. While evidence suggests that ACT in other populations can be delivered effectively in as little as one face-to- face session, little is known about the 'dosage' required for online, self-guided interventions. If our shorter ACT for Caregivers protocol is effective in improving caregiver outcomes, the program will move forward towards the implementation goal of being offered for free (or at very low cost) through Utah State University's Alzheimer's Research Center.

The ACT for Caregivers Stage I pilot study (with the longer 10-session format) demonstrated improved outcomes but inadequate power to examine more nuanced mechanisms for change, and without qualitative data collected. With a larger sample, the present study allows for adequate power to examine change mechanisms quantitatively. Qualitative interviews and mixed methods approaches are added to the current study to understand change, and how ACT-related skills contribute to change. Although fully longitudinal mixed methods research is becoming more common in health research, it is still novel in program development and evaluation with ADRD caregivers. Fully longitudinal mixed methods research allows for a holistic examination of whether and how change occurs over time and is therefore highly relevant for evaluating promising intervention programs in the growing population of family caregivers for persons with ADRD.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Treatment; Receives access to the online ACT course immediately after enrollment	Behavioral: Acceptance and Commitment Therapy; Acceptance and commitment therapy (ACT) combines the skills of acceptance, cognitive defusion, being present, self as context, values, and committed action to help individuals engage with a meaningful life. A goal of ACT is to help people develop psychological flexibility, meaning they can experience and live with difficult thoughts and emotions, and still pursue what matters to them. The current project is an online, self-guided, 6-session intervention. Each session is expected to take about 30 minutes each, and the entire course will take approximately 3-4 weeks to complete, as users are encouraged to take a few days in between sessions. Within each session, participants will read about concepts and ACT metaphors, apply ACT concepts to general and care- specific vignettes, and apply ACT concepts to their own lives and care situations. Interactive experiences are included in each session and ends with a printable summary with practice skills before proceeding.
No Intervention: Waitlist; Receives access to the online ACT course 30 days after enrollment

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Description of participant experience using this intervention	Qualitative interviews will capture how participant experiences support, refine, and contradict acceptance commitment therapy (ACT) principles.	30 days
Change from Post intervention experience at Follow up	Qualitative interviews will capture changes in participant's attitudes and enactment of principles learned during the treatment.	30 days after access to program to 6 weeks later
Mean group (waitlist/treatment) differences in caregiver burden	Group differences between waitlist and treatment group scores after the treatment group has had access to the treatment for 30 days and the waitlist group has not received any intervention for the same amount of time. Caregiver burden is measured by a 12-item [short] caregiver burden scale. Participants rate the impact of caregiving on multiple aspects of health (response range 0 never to 4 nearly always). A total possible summed scores range from 0 to 48; higher scores indicate higher burden.	30 days
Mean group (waitlist/treatment) differences in depressive symptoms	Group differences between waitlist and treatment group scores after the treatment group has had access to the treatment for 30 days and the waitlist group has not received any intervention for the same amount of time. Depressive symptoms are measured by 10-item [short] Center for Epidemiological Studies Depression Scale (CES-D). Participants rate the frequency of depressive symptoms during the past week. Responses range from 1 rarely or none of the time to 4 all of the time, with possible summed scores ranging from 10 to 40; higher scores indicate more depressive symptoms.	30 days
Mean group (waitlist/treatment) differences in positive aspects of caregiving	Group differences between waitlist and treatment group scores after the treatment group has had access to the treatment for 30 days and the waitlist group has not received any intervention for the same amount of time. Positive aspects of caregiving will be measured using a 9-item Positive Aspects of Caregiving measure. Items use the following stem "Providing help to (name) has…", with example items such as "made me feel useful" and "enabled me to appreciate life more." Responses range from 1 disagree a lot to 5 agree a lot, and items are summed with a possible score range from 9 to 45; higher scores indicate more positive aspects of caregiving.	30 days
Mean group (waitlist/treatment) differences in sleep quality	Group differences between waitlist and treatment group scores after the treatment group has had access to the treatment for 30 days and the waitlist group has not received any intervention for the same amount of time. Sleep quality will be measured by a 1-item Sleep Quality Scale ranging from 0 terrible to 10 excellent, with higher scores indicating higher quality. Respondents are asked to consider the overall quality of sleep on most nights over the last seven days only.	30 days
Mean group (waitlist/treatment) differences in psychological flexibility	Group differences between waitlist and treatment group scores after the treatment group has had access to the treatment for 30 days and the waitlist group has not received any intervention for the same amount of time. Psychological flexibility will be measured by the 23-item CompACT consisting of three subscales: openness to experience (10 items; possible score range 0 to 60), behavioral awareness (5 items; possible score range 0 to 30), and valued actions (8 items; possible score range 0 to 48). Responses range from 0 strongly disagree to 6 strongly agree. Some items are reverse scored. Lower scores indicate more psychological flexibility.	30 days
Mean group (waitlist/treatment) differences in quality of life	Group differences between waitlist and treatment group scores after the treatment group has had access to the treatment for 30 days and the waitlist group has not received any intervention for the same amount of time. Quality of life will be measured by a 1-item visual analogue scale ranging from 0 to 100, with higher scores indicating higher quality of life.	30 days
Within person change from Pretest measures at Posttest and Follow up in caregiver burden	Change over time for all participants comparing scores from before the intervention, to after 30 day of access to the treatment, and again 6 weeks after the end of the initial 30 day period. Caregiver burden is measured by a 12-item [short] caregiver burden scale. Participants rate the impact of caregiving on multiple aspects of health (response range 0 never to 4 nearly always). A total possible summed scores range from 0 to 48; higher scores indicate higher burden.	Pretest before intervention, 30 days of treatment access, and 6 weeks after initial 30 day period
