Family caregivers of persons with Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD) experience caregiving-related distress and have about 650% higher rates of suicide ideation (SI; 32.32%) compared to the general population (4.3%). Dialectical Behavior Therapy (DBT), an evidence-based intervention for suicide, addresses multiple areas of psychosocial functioning. Standard DBT is often too re-source-intensive (6 months to 1 year of weekly individual sessions and 1.5-2.5-hour weekly skills training group sessions) and is not tailored to family caregivers of persons with AD/ADRD with SI, creating a significant barrier to SI treatment. The investigators will develop, implement, and evaluate an adapted DBT skills training groups tailored to the unique experiences and needs of family caregivers of persons with AD/ADRD to reduce suicide-related out-comes most effectively. Our specific aims are: (1) Adapt DBT skills groups for family caregivers (of persons with AD/ADRD) endorsing direct or indirect SI (directly stated SI vs. indirect indicators of SI) to ensure it applies to direct and indirect SI and considers SI underreporting; (2) Evaluate the feasibility, acceptability, and fidelity of the adapted DBT skills groups in this sample; (3) Assess preliminary effectiveness indicators of the adapted DBT skills groups. For Aim 1, a panel of experts and two stakeholders (Garrison Institute on Aging (GIA) staff; family caregivers of a person with AD/ADRD), will inform the adaptation of DBT skills training to family caregiv-ers of persons with AD/ADRD and shorten to 16 weekly, 1-hour skills groups sessions, over 4 months. For Aims 2 and 3, the investigators will implement the adapted DBT skills training groups among family caregivers of persons with AD/ADRD with direct/indirect SI at screening while providing respite, all at GIA. The investigators will collect relevant demo-graphic data from family caregivers and family caregiver-reported data about the person with AD/ADRD. Over 18 time points (baseline, following weekly DBT sessions, follow-up), participants will complete self-report assessments targeting DBT fidelity/acceptably, SI (direct and indirect), and suicide risk correlates. The investigators will also record DBT session to monitor fidelity. The investigators will track participant recruitment, group attendance, retention as feasibility metrics. The investigators will also use innovative methodology by collecting inflammation biomarkers and heart rate variability data as an indirect SI assessment. Lastly, the investigators will conduct focus groups after the intervention for addi-tional qualitative acceptability and feasibility data. The investigators will also survey GIA site staff to evaluate their perceived acceptability and feasibility of the intervention at GIA. Our hypotheses are that 1) our adapted DBT skills group will be feasible, acceptable, and maintain DBT fidelity, and 2) SI (direct and indirect), suicide risk factors, and inflammation will decrease, and heart rate variability will increase post intervention. Our expected outcomes are to have a scalable DBT group intervention for family caregivers of persons with ADRD, indications of feasibility and acceptability, and preliminary effectiveness indicators. This work will provide a life-saving suicide prevention approach for family caregivers of persons with AD/ADRD, provide students with multidisciplinary research experiences, and significantly strengthen our university research environment.
