An interventional study of COMA-F in Coma and Emotional Distress, sponsored by Massachusetts General Hospital. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-05-25.
Sponsored by Massachusetts General Hospital · Not applicable, Interventional, and Prevention
The purpose of this study is to pilot a psychosocial skills-based intervention for caregivers of patients with severe acute brain injuries. The data the investigators gather in this study will be used to further refine our COMA-F intervention.
The goal of this study is to refine our proposed intervention (COMA-F) through an open pilot. The investigators will deliver an open pilot of the intervention (N=15 caregivers) to evaluate initial feasibility and acceptability using exit interviews and pre-post assessments.
The open pilot will take place at the Massachusetts General Hospital, University of North Carolina School of Medicine, and University of Maryland School of Medicine neurological intensive care units (NICUs) or step-down units using our established methodology successfully implemented during our previous R21 of our Recovering Together study. Study clinicians will deliver 6, 30 minute sessions of the intervention (at bedside or on Zoom, depending on participant preference). All participants will complete measures at baseline, and after completion of program (6 weeks). They will also complete measures of emotional distress weekly. At the completion of the program, participants will engage in a 5-10 minute exit interview where they will provide feedback of the intervention.
Eligible caregivers must be caregivers of patients considered to have severe acute brain injury and be unable to communicate with their loved one or clinical team due to their incapacitated nature. Caregivers must meet the following inclusion criteria:
Confirmed by the primary clinical team as the primary caregiver for a patient who:
a. Is age 18 or older; b. Has been admitted to the ICU with a severe acute brain injury: i. Ischemic stroke ii. Intracerebral hemorrhage iii. Subarachnoid hemorrhage iv. Traumatic brain injury v. Hypoxic-ischemic encephalopathy; c. In the judgment of the medical team, has had a Glasgow Coma Scale score below 9 while not intubated OR an inability to following meaningful commands while intubated at any point during his or her hospitalization course for greater than 24 consecutive hours, felt to be due to the brain injury itself and not a confounding factor (i.e., sedation, seizures, etc.); d. Is still alive in the ICU at the time that the clinical team approaches the primary caregiver about possible recruitment; e. Has a prognosis for survival of greater than 3 months and does not have a concurrent diagnosis of a terminal illness or injury, as judged by the clinical team.
Exclusion Criteria:
Patient has terminal diagnosis
Caregiver has:
Caregivers will participate in 6 30-minute skills sessions. A clinical psychologist will deliver all of the sessions. The main intervention goal is to provide dyads with resiliency skills to reduce emotional distress and prevent chronic distress.
Behavioral: COMA-F
The intervention will teach resiliency skills (mindfulness, coping, interpersonal communication, etc.) to the comatose patient's caregiver. These sessions will take place in person or on Zoom, depending on the participant's preference.
Preliminary feasibility of recruitment
We will assess the proportion of caregivers enrolled from the number of caregivers eligible.
Time frame: 0 weeks
Preliminary feasibility of assessments
We will assess the proportion of caregivers enrolled that completed all assessments.
Time frame: Change from pre-test (0 weeks) to post-test (6 weeks).
Preliminary feasibility of adherence
We will assess the proportion of enrolled caregivers that complete 4 out of 6 sessions.
Time frame: Change from pre-test (0 weeks) to post-test (6 weeks).
Preliminary feasibility of therapist fidelity
We will assess the number of sessions in which the therapist adhered 100% to the treatment manual based on a fidelity checklist.
Time frame: Change from pre-test (0 weeks) to post-test (6 weeks).
Preliminary treatment satisfaction
We will assess the proportion of enrolled caregivers that score above the midpoint on the Client Satisfaction Questionnaire-3. Scores range from 3 to 12; higher values indicate greater satisfaction.
Time frame: post-test (6 weeks after session 1)
Preliminary treatment credibility
We will use the Credibility and Expectancy Questionnaire (CEQ) to assesses caregivers perceptions that the treatment will work after learning about the study. Scores range from 3-27; higher ratings indicate more belief that the program is logical and will help with the intended outcome.
Time frame: post-test (6 weeks after session 1)
Hospital Anxiety and Depression Scale (HADS)
We will use the Hospital Anxiety and Depression Scale HADS, a 14-item measure that assesses symptoms of emotional distress (anxiety and depression). The anxiety and depression sub-scale are each scored from 0-21, with higher scores indicating greater severity of symptoms. Scores can be summed to create a global emotional distress score (0-42).
Time frame: Change from pre-test (0 weeks) to post-test (6 weeks)
Posttraumatic Stress Disorder Checklist-5
Post-Traumatic Stress Disorder Checklist - 5; range 0-80, higher scores indicate greater posttraumatic stress
Time frame: Change from pre-test (0 weeks) to post-test (6 weeks)
Cognitive and Affective Mindfulness Scale-Revised (CAMS-R)
Cognitive and Affective Mindfulness Scale-R (CAMS-R); 12-48, higher scores indicate greater perceived mindfulness
Time frame: Change from pre-test (0 weeks) to post-test (6 weeks)
Measure of Current Status Part A (MOCS-A)
Measure of Current Status Part A (MOCS-A); 0-52; higher scores indicate greater perceived ability to cope
Time frame: Change from pre-test (0 weeks) to post-test (6 weeks)
Toronto Mindfulness Scale-Trait (TMS-Trait)
Toronto Mindfulness Scale-Trait (TMS-Trait); 0-52, higher scores indicate greater perceived mindfulness (specifically curiosity and de-centering)
Time frame: Change from pre-test (0 weeks) to post-test (6 weeks)
Enhancing Recovery in Coronary Heart Disease Social Support Instrument (ESSI)
Enhancing Recovery in Coronary Heart Disease Social Support Instrument (ESSI); the ESSI measures the participant's range of social support in their life. Higher scores indicated higher levels of social support. Total scores range from 8 to 34.
Time frame: Change from pre-test (0 weeks) to post-test (6 weeks)
