However, the impact of poor sleep on daily affect among CP, and the reverse relationship, remains unclear. This study examined daily variations in positive and negative affect and their relationship with poor sleep using data from an ongoing clinical trial involving dementia care dyads. A total of 72 CP completed ecological momentary assessment surveys of their positive and negative affect (three times a day) and sleep of CP and PLWD for seven days. Variables included positive (feeling energetic, happy, motivated, rested, relaxed) and negative affect (feeling anxious, depressed, helpless, hopeless, nervous, tense, worried, worthless), and ‘good sleep’(no trouble falling asleep and staying asleep) on previous nights. Descriptive and mixed-effects regression models were conducted. Positive affect was higher in the morning compared to midday and evening. Negative affect was lower in the evening than the morning, and higher at midday than in the morning. The relationship between positive affect and the previous night’s CP sleep differed significantly between the morning and the evening (β = 0.079, p = 0.049) . In a lagged mixed-effect model, negative affect was significantly related to the next day’s sleep for both CP and PLWD. Higher levels of negative affect were associated with a greater likelihood of poor sleep for both dyad members (β = 1.435, p= 0.007 for CP; β = 1.398, p= 0.038 for PLWD) . Understanding daily affect fluctuations is essential for improving sleep among dementia care dyads.  \nAbstract citation ID: igaf122.311  \nFAMILY CARE PARTNERS’ DAILY AFFECT AND SLEEP  \nIN DEMENTIA CARE DYADS USING ECOLOGICAL  \nMOMENTARY ASSESSMENT  \nYeonsu Song1, Raeanne Moore2, Brent Mausbach2,  \nJennifer Martin3, and Mary-Lynn Brecht1, 1.
