and 4) whether there is a remaining association not mediated by these factors. Methods We used cross-sectional data from the Canadian Longitudinal Study on Aging (N= 17,938), focusing on working, non-retired adults aged 45-64 years. Data were collected via telephone and in-person interview over the 2011-2015 period. Functional, psychosocial, organizational and life-stage factors were measured using existing variables to create composite index scores. Path models examined the relationship

... age and retirement expectations, and the proportion of the relationship explained via each factor. Results Age was associated with functional, psychosocial, organizational and life-stage scores in expected directions. Older age also was associated with earlier retirement expectations. Path models found that 25-30% of the total relationship between older age and retirement expectations was mediated through life-stage and organizational factors. Conclusion Our study demonstrates the feasibility of measuring functional, psychosocial, organizational and life-stage concepts via existing data to better understand age-related inequalities in retirement expectations. Future research should focus on measuring additional items for psychosocial and organizational factors, followed by validation of the extent to which each item explains age differences in other work outcomes.
