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.

Abstract Complicated grief (CG) is characterized by lengthy, intense, and functionally impairing grief which disproportionately affects older adults. Accelerated Resolution Therapy (ART) is a brief, protocol driven, exposure/imagery rescripting therapy which uses lateral left-right eye movements. ART, unlike traditional psychotherapy, directs the person to perform two tasks simultaneously (e.g. re-experiencing the grief experience and performing eye movements), taxing limited working memory capacity. Importantly, this may force memory traces representing events, emotions, and sensations to compete for permanence, as well as reduce the vividness and emotional intensity of the original grief. Two CG case studies are presented (expected; unexpected death) with their response to ART. Stake’s instrumental case study methodology was used to identify and study cases which reflect a range of CG. Additionally, CG was measured by the Inventory of Complicated Grief (ICF). ICF’s range is 0-76 with scores &gt; 24 indicating CG. Case 1 was a spousal caregiver with a single, expected death where helplessness, guilt, shame, and a life alone had resulted in CG (baseline ICF 33). Her ICF at 8 weeks post-ART was 10. Case 2 was an adult child caregiver with multiple (parent, sibling), unexpected deaths in quick succession where loss, guilt, anger, and helplessness had resulted in CG (baseline ICF 25). Her ICF at 8 weeks post-ART was 9. Both participants were able to process the distressing sensations that emerged during the imaginal exposure component facilitated with the use of eye movements. This suggests that ART may be a powerful new mind-body treatment for CG.
