Using conditional growth mixture modeling (GMM-CV), the study examines longitudinal loneliness trajectories and whether cognitive function—immediate word recall, delayed word recall, and serial 7s—predicts trajectory membership. Data from 3,944 older adults across eight Health and Retirement Study waves (2006–2020) identify three classes: low-stable, high-decreasing, and moderate-increasing loneliness.

Data were drawn from a sample of 3,944 older adults (Mage = 68.74) using eight waves of the Health and Retirement Study (HRS) data from 2006–2020. Data from every two years were pooled to increase the sample size and create four time points. GMM-CV in Mplus identified three distinct loneliness trajectories best fit the Data: LL= -25,495 .269, BIC=51,214 .097, SSABIC=51,128.303, Entropy=0.814, Adj. LMR-LRT (.52)=245.630, BLRT(.51)=255.518. The three identified classes were: Class 1: Low-Stable Loneliness (75 .6%), Class 2:  \nHigh-Decreasing Loneliness (13.1%), and Class 3: Moderate-Increasing Loneliness (11.3%). The mean group differences revealed significant group differences in immediate word recall at time 1 (F=3.19, p=.04) and time 4 (F=3.9, p=.02), delayed word recall at time 1 (F = 3.31, p=.037) and time 4 (F = 3.11, p=.045), while no significant effect was found for serial 7s at time  \n1 (F=2.33, p=.098) and time 4 (F=.068, p=.934). Immediate word recall at time 4 exhibited a significant negative effect on the loneliness slope, indicating that higher cognition scores were associated with a less steep increase in loneliness over time. These findings suggest enhancing cognitive function as a potential intervention to reduce loneliness in later life. Future research should explore underlying mechanisms and moderating factors.  \nAbstract citation ID: igaf122.2188  \nGROWTH MIXTURE MODELING OF LONELINESS  \nTRAJECTORIES IN OLDER ADULTS: THE ROLE OF  \nCOGNITIVE FUNCTION  \nElnaz Abaei, and Peter Martin, Iowa State University, Ames, Iowa, United States  \nLoneliness is a growing public health concern among older adults in the United States, with significant implications for cognitive function.
