Notes: ^aThe table summarizes results of separate survey year regressions of task measures on the criterion variables. If not explicitly stated for single years, the association are at least statistically significant at the p≤.05-level and have the reported signs in all separate regressions. “−” signifies a stat. sig. negative association with the criterion variable, “+” signifies a stat. sig. positive association with the criterion variable. ^bFor detailed variable description see Sect. 3.3 and Table 8 in the Appendix. ^cDeviating from the operationalization as shown in Table 7, manual only includes “working standing”. Sample is restricted to people from the western part of Germany belonging to the labor force (defined as having a paid work) aged 15 to 65, with a regular working time of at least ten hours per week.
