“…In addition, it should be noted that the Nagelkerke R Squares were quite low (see Tables 3 and 4 ), indicating that besides prior SA, DP, and the sociodemographic covariates, there were other factors that can explain work participation past the age of 65 than those accounted for in this model. Such factors could, e.g., be influence by significant others [ 15 , 55 ], the employer [ 11 ], societal and group norms regarding retirement [ 56 ], work environment [ 22 , 51 ], motivation to continue in paid work [ 22 ], personality [ 57 ], type of morbidity, as well as duration, rate (part- or full-time), and number of SA and DP spells. Moreover, one limitation is the possible overlap between SA and DP, which might affect the results of the analysis in which SA and DP were separate exposure variables.…”
