Our manuscript provides additional support for the pleasant events and activity restriction model (Mausbach et al., 2011; Chattillion et al., 2013), by highlighting the importance of considering caregiving stressors as a source of caregivers' activity restriction in the theoretical framework of the model. Scar and vulnerability models assert that increased psychopathology may predict subsequent executive functioning (EF) deficits (and vice versa) over protracted timescales, yet most prior work on this topic has been cross-sectional. Thus, we tested the within- and between-person relations between EF, depression, and anxiety. Older adult participants (n=856) were assessed across four waves, approximately 2years apart. Performance-based EF and caregiver-rated symptom measures were administered. Bivariate latent change score and random-intercept cross-lagged panel models were conducted. Within persons, random-intercept cross-lagged panel models revealed that prior greater depression forecasted lower subsequent EF, and vice versa (d=-0.292 vs. -0.292). Bivariate dual latent change score models showed that within-person rise in depression predicted EF decreases, and vice versa (d=-0.245 vs. -0.245). No within-person, cross-lagged, EF-anxiety relations emerged. Further, significant negative between-person EF-symptom relations were observed (d=-0.264 to -0.395). Prospective, within-person findings offer some evidence for developmental scar and vulnerability models.
