Abstract Complicated grief (CG), severe, prolonged (>12 months) grieving, disproportionately affects older adults. A prospective two-group, waitlisted RCT examined whether four sessions of Accelerated Resolution Therapy (ART) was effective in informal caregivers by comparing pre-to-post ART changes and investigating variation in treatment response by baseline CG levels. Inclusion: ≥60 years, Inventory of Complicated Grief >25. Paired t-tests of mean (SD) differences compared pre- to post-ART; pre-ART to 8-week follow-up, and post-ART to 8-week follow-up; then stratified by median baseline level of CG. Mean (SD) age of 54 participants was 68.7 (7.2) years, 85% female, and 93% white. Significantly greater CG reduction (-22.8 (10.3)) vs. waitlist (-4.3 (6.0)) was found. Within-participant effect sizes from baseline to 8-weeks post treatment were 1.96 (95% CI: 1.45, 2.47; p<0.0001). Treatment effects did not substantially differ by baseline levels. Lesson learned was that it was possible to successfully recruit and treat CG in the community.

Biomarkers may serve as objective measures in complicated grief (CG) potentially capturing responses to stress reduction treatment. This paper reports challenges in obtaining and assessing salivary cortisol and α-amylase (sAA) for a recent randomized clinical trial. Within-session changes in salivary cortisol and sAA for 54 older adults with CG who received Accelerated Resolution Therapy were compared with perceived stress measured by Subjective Units of Distress Scale. Bivariate correlations and multiple regressions examined changes in biomarkers. Protocols, study logs, and audit reports identified challenges. Challenges included obtaining unstimulated passive drool salivary samples and their analyses. Our sample of older females on multiple medications may have resulted in a perfect storm of moderating and intervening variables which affected the stress response. This paper contributes to the discussion on designing clinical trials for older adults which must account for physiologic changes, multimorbidity, and polypharmacy common in this population and makes recommendations moving forward.

Background and Objectives: Complicated grief (CG) is severe, prolonged (>12 months) grieving. Complicated grief disproportionately affects older adults and is associated with negative physical/psychological effects. Although treatment options exist, those which do are time-intensive. We report on a randomized clinical trial (RCT) which examined whether accelerated resolution therapy (ART), a novel mind-body therapy, is effective in treating CG, post-traumatic stress disorder (PTSD), and depression among hospice informal caregivers. Research Design and Methods: Prospective 2 group, wait-listed RCT. All participants were scheduled to receive 4 ART sessions. Inclusion: ≥60 years, inventory of CG >25, and PTSD checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition >33 or Psychiatric Diagnostic Screen Questionnaire PTSD subscale >5. Exclusion: Major psychiatric disorder, other current psychotherapy treatment. Depression was measured by the Center for Epidemiologic Studies Depression. Results: Mean (standard deviation [SD]) age of 54 participants was 68.7 (7.2) years, 85% female, and 93% white. Participants assigned to ART reported significantly greater mean (SD) CG reduction (−22.8 [10.3]) versus Wait-list participants (−4.3 [6.0]). Within-participant effect sizes (ESs) for change from baseline to 8-week post-treatment were CG (ES = 1.96 (95% confidence interval [CI]: 1.45-2.47; P < .0001), PTSD (ES = 2.40 [95% CI: 1.79-3.00]; P < .0001), depression (ES = 1.63 [95% CI: 1.18-2.08; P < .0001). Treatment effects did not substantially differ by baseline symptom levels. Discussion and Implications: Results suggests that ART presents an effective and less time-intensive intervention for CG in older adults. However, it should undergo further effectiveness testing in a larger, more diverse clinical trial with a focus on determining physiological or behavioral mechanisms of action.
