Work-Family Interpersonal Capitalization: Sharing Positive Work Events at Home In recent years, there has been an increased interest in the implications of work events and experiences for employees’ affective states at work and the effects of these states on behavioral and attitudinal job outcomes. However, research has largely failed to consider the ways in which employees react to or process work events beyond the confines of the workplace, and there has been no research examining behavioral actions that employees can take in the family domain to capitalize on positive work events or experiences. In addition, no study has tested an integrated model including day-to-day relationships between actual work events, affective states, and daily job satisfaction. To address these gaps in the literature, an experience sampling study involving daily surveys taken over the Internet at work and daily surveys taken on palmtop devices at home by full-time employees, as well as multiple reports provided by spouses or significant others, was conducted over a period of three weeks. This study examined the relationships between work events, affective states, and daily job satisfaction at the within-individual level, as well as the implications of discussing positive work events and experiences with one’s spouse or partner at home – what is termed work-family interpersonal capitalization – for employees’ job satisfaction and for their satisfaction concerning their relationship with the person with whom the events are shared. Results generally supported the hypothesized effects: across the days of the study positive events indeed influenced job satisfaction through positive affect, and work-family interpersonal capitalization on the most positive work event of day had a positive effect on job satisfaction over and above the effects of the event’s pleasantness and of the number of other positive work events experienced that day. The implications of the study’s finding for theory, research, and practice are discussed. (Javascript is required to view Mediasite content)
