RT Journal Article T1 The Effect of Age on Daily Positive Emotions and Work Behaviors A1 Dello Russo, Silvia A1 Antino, Mirko A1 Zaniboni, Sara A1 Caetano, Antonio A1 Truxillo, Donald AB This study draws on socioemotional selectivity and person–job fit theories to investigate the emotional bases for age-related differences in daily task crafting and in-role performance. We tested a mediation model in which age is related to positive emotions that in turn predict task crafting and in-role performance. A total of 256 people working in multiple organizations participated in a 5-day diary study. Multilevel modeling showed that, at the person level of analysis, age is significantly and positively related to positive emotions and task crafting and, via crafting, to in-role performance. No significant mediation of high- and low-arousal positive emotions was found between age and task crafting. However, at the day level of analysis, high-arousal positive emotions are positively related to task crafting, and this in turn is positively related to in-role performance. These findings make important theoretical contributions to understanding within-person processes associated with employee age in addition to more traditional between-person factors. They also have implications for managing an age-diverse workforce by means of job crafting.
