To date, little is known about contextual factors surrounding suicidal ideation among ADRD family caregivers. We investigated individual caregiver characteristics (gender, age, relationship to care-recipient, history of depression and anxiety) and daily environmental stressors (behavioral symptoms of dementias; BSDs) associated with daily suicidal ideation using a micro-longitudinal design and ecological momentary assessment methods. Data were collected from a national sample of family caregivers (N=51) who completed daily diaries over 21 days (n=911). Suicidal ideation was endorsed on forty-seven days (5.16%) during the sampling period, with 11 participants (22%) endorsing suicidal ideation at least once. Suicidal ideation did not differ based on the caregiver’s age and relationship to the care-recipient (spouse or child). Participants with a history of mild depression and anxiety endorsed more days with suicidal ideation. Finally, family caregivers were more likely to endorse suicidal ideation on a day when more than one type of BSD was reported (OR = 1.25, 95% CI: 1.04-1.50, p = 0.018) and when BSDs were perceived as more bothersome than average (OR = 1.12, 95% CI: 1.05-1.19, p < 0.001). In this investigation, we identified descriptive and predictive factors that will inform the development of targeted interventions for ADRD caregivers at high risk of suicidal ideation.
