Yet the mechanisms through which loneliness shapes their emotional well-being and caregiving outcomes remain unclear. Guided by stress process and attachment frameworks, we tested both momentary and longitudinal effects of loneliness in AD/ADRD spousal caregivers. Participants (N =69; mean age = 71.5 years; 64% female; 62% White) completed ecological momentary assessments of loneliness and affect, along with baseline and follow-up surveys of caregiver burden, depressive symptoms, and anticipatory grief.  \nMultilevel models showed that within-person increases in loneliness predicted greater depressed affect (b=0.72, p \u003C .001), controlling for demographics. Longitudinally, higher baseline loneliness predicted increases in caregiver burden (b=0.21, p = .02) and anticipatory grief (b=0.01, p = .01), but not depressive symptoms, beyond prior levels. Moderation analyses indicated that attachment anxiety heightened vulnerability to depressed affect, whereas attachment avoidance buffered the within-person daily link between loneliness and depressed affect. Findings demonstrate that loneliness functions as both a dynamic daily process and a long-term vulnerability factor in AD/ADRD spousal caregiving. By identifying attachment insecurity as a risk amplifier, this work provides mechanistic insight into when and for whom loneliness is most detrimental and highlights loneliness as a promising intervention target to reduce burden, mitigate anticipatory grief, and promote resilience among AD/ADRD spousal caregivers.","cbCaif0AQJwoZLMY","https://ap.wps.com/l/cbCaif0AQJwoZLMY","pdf",1118185,"English","# Study Aim\n## Momentary and Longitudinal Design\n# Methods\n## Participants and Measures\n# Results\n## Within-Person Effects\n## Longitudinal Predictors\n## Moderating Role of Attachment\n# Implications\n## Mechanistic Insight and Intervention Targets","[{\"question\":\"How does loneliness affect caregivers in the short term (momentary effects)?\",\"answer\":\"Within-person increases in loneliness predicted greater depressed affect, after controlling for demographics.\"},{\"question\":\"What loneliness-related outcomes changed over time in the longitudinal analysis?\",\"answer\":\"Higher baseline loneliness predicted increases in caregiver burden and anticipatory grief beyond prior levels, but it did not predict increases in depressive symptoms.\"},{\"question\":\"How do attachment styles influence the loneliness–depressed affect relationship?\",\"answer\":\"Attachment anxiety heightened vulnerability to depressed affect, while attachment avoidance buffered the daily within-person link between loneliness and depressed affect.\"}]","MOMENTARY AND LONGITUDINAL EFFECTS OF LONELINESS ON DEMENTIA CAREGIVER WELL-BEING - No. 1275 - Abstract citation ID igaf122.4254 | PDF",1790641524]
