University of Heidelberg, Heidelberg, Baden- Wurttemberg, Germany Sleep and physical well-being (e.g., pain, self-rated health) are closely linked, but the temporal ordering, especially re- garding day-to-day variations, is not well understood. Furthermore, sleep quality and duration are only moderately correlated and may differ in their association with physical wellbeing. Using data from 123 young-old (66-69 years, 47% women) and 47 old-old adults (84-90 years, 60% women) who rated sleep quality and duration as well as pain and self-rated health on seven consecutive days, we examined bidirectional links between sleep and physical well-being. Supporting our hypotheses, results showed that after longer and better than usual sleep, participants reported better self- rated health; only better sleep quality signifcantly predicted lower pain. In turn, both lower pain intensity and increased self-rated health predicted better subsequent sleep quality, but not duration. We discuss conceptual and practical impli- cations of our fndings. PERCEIVED QUALITY OF DAILY SOCIAL INTERACTIONS: THE ROLE OF INTERACTION MODALITY Gizem Hueluer 1 , Minxia Luo 2 , Birthe Macdonald 2 , and Carlotta Grünjes 1 , 1. University of Bonn, Bonn, Nordrhein-Westfalen, Germany, 2. University of Zurich, Zurich, Zurich, Switzerland Older adults increasingly use digital technologies to com- municate with others. In the present study, we examine the role of interaction modality (face-to-face, telephone, digital) for perceived quality of social interactions. We use data from 118 participants (age: M = 72 years, SD = 5, range = 65 to 94; 40% women), who reported on their social interactions over 21 days in an event-contingent experience sampling study. Relative to face-to-face interactions, participants re- ported feeling more accepted and calmer, but also less happy in telephone interactions. They perceived telephone interactions as more meaningful, but also as less pleasant. Relative to face-to-face interactions, participants felt less ac- cepted, less close to their interaction partner, and less happy in digital interactions and they perceived digital interactions as less pleasant. In summary, our fndings suggest that the modality of daily social interactions is related to their quality. We discuss implications of these fndings for future research. DAILY ACTIVITY DIVERSITY AND DAILY WORKING MEMORY IN COMMUNITY-DWELLING OLDER ADULTS Minxia Luo 1 , Robert Moulder 2 , Laura Breitfelder 3 , and Christina Röcke 4 , 1.

University Research Priority Program (URPP) Dynamics Of Healthy Aging, University Of Zurich, Zurich, Zurich, Switzerland, 4. University of Zurich, Dynamics of Healthy Aging & Center for Gerontology, Zurich, Zurich, Switzerland Research has shown that diverse activity engagement has positive effects on cognitive functioning in older age. However, it is unknown whether the positive effect holds within persons across days and across people. We examined daily within-person association between activity diversity and working memory in older age and effects of potential moderators therein. We examined 16-day smartphone-based ambulatory assessment data from 150 older adults (aged 65+). Participants reported their present activities and com- pleted working memory tasks seven times per day. Within persons, higher daily activity diversity was positively asso- ciated with higher daily working memory. Moreover, the prior day’s activity diversity led to that day’s higher working memory, but not vice versa. We did not fnd any moderating effects of age, education, or fuid and crystallized intelligence. Our results strengthen the evidence on the benefcial effect of activity diversity on cognitive performance. Results are dis- cussed in the context of cognitive reserve theory. CAREGIVER HEALTH LITERACY AS A MODIFIABLE TARGET TO PROMOTE OLDER ADULT HEALTH Rachel O'Conor, Morgan Eifer, Lauren Opsasnick, Laura Curtis, Julia Yoshino Benavente, Lee Lindquist, and  Michael Wolf, Northwestern University, Chicago, Illinois, United States Many older adults receive assistance in managing chronic conditions. Yet complicating the utility of caregiver support is whether caregivers have suffcient skills to aid in a patient’s self-care. Health literacy (HL) is as an important determinant of older adults’ health outcomes, but few studies have exam- ined caregiver HL and patient outcomes. We interviewed 162 patient-caregiver dyads during an ongoing cognitive aging cohort study to examine associations between caregiver HL, measured using the Newest Vital Sign, and older adults’ health outcomes. Physical function and mental health symp- toms were assessed using PROMIS short form assessments. Patients’ also self-reported emergency department (ED) visits and hospitalizations over the past 12 months. Chi-square and t-tests were performed, as appropriate. Patients were on average 73 years old and managing 4 comorbidities. The ma- jority were female (70%), identifed as Black (35%) or White (60%). Caregivers’ mean age was 64 years; half were female (56%) and had limited HL (48%). Limited caregiver HL was associated with poorer physical function (M=43.0 (8.5) vs. M=46.0 (9.1), p=0.05), greater comorbidities (M=4.0 (1.9) vs M=3.3 (1.8), p=0.02) and more ED visits in the past year (36.7% vs. 19.3%, p=0.01). No differences by caregiver HL were observed for patients’ mental health or hospitalization. Findings suggest that caregivers with limited HL are caring for medically complex patients, and further research should examine whether limited caregiver HL leads to poorer self-management of chronic conditions. The development of HL training for caregivers may better equip them to assist older adults and improve older adult health.
