Supplemental Material for The Role of Task Persistence in Young Adolescence for

Successful Educational and Occupational Attainment in Middle Adulthood

This appendix provides tables for the multiple and ordinal regression analyses in which men and women were analyzed together including covariates of gender and an interaction term for gender and task persistence. TASK PERSISTENCE AND ATTAINMENT 2

Notes. NR2 = Nagelkerke’s peudo R-square.

The gender and task persistence variables were centered. The centered gender variable had men coded in the negative category and women in the positive category. aThe regression coefficient for gender refers to the effect of belonging to the men category.
