Thus far, few cross-sectional studies have investigated the association between pet ownership and psychosocial factors. As longitudinal studies on this topic are mostly lacking, this study aimed to analyze the association between pet ownership and psychosocial factors (in terms of depressive symptoms, loneliness, social isolation, and life satisfaction) using a longitudinal approach. The data used were taken from the German Ageing Survey (DEAS), a nationally representative sample of community-dwelling middle-aged and older adults (n = 12,438 observations). Two waves were used (year 2014 and year 2017). Validated multi-item scales were used to measure psychosocial factors. Linear fixed effects (FE) regressions were performed. In summary, only a few significant longitudinal associations were detected in regression analyses. No associations between general pet ownership and psychosocial factors were found. However, cat ownership was significantly longitudinally associated with increases in loneliness levels among the total sample and men. Cat ownership was also significantly longitudinally associated with increases in social isolation levels among men. Among women, dog ownership was significantly longitudinally associated with decreases in life satisfaction. This study reveals some associations between pet ownership and unfavorable psychosocial factors longitudinally. These associations were only significant for subgroups (cat vs. dog ownership and females vs. males).
