Workplace intrusions and employee strain: the interactive effects of extraversion and emotional stability.

Background/objectives: Intrusions are a type of workplace interruption defined as unexpected interpersonal contact that disrupts workflow. Drawing from the Job Demands-Resources model of work stress, we examined how two personal resources - extraversion and emotional stability - influence relations among intrusions and strain outcomes.

Design/methodology: Self-reported, online questionnaire data were collected from two samples; 323 faculty and staff from a university (sample 1) and 574 full-time employees recruited from an online crowdsourcing forum (sample 2).

Development and validation of the Workplace Interruptions Measure.

In 3 studies, we developed and tested the first comprehensive, self-report measure of workplace interruptions. The Workplace Interruptions Measure (WIM) is based on a typology of interruptions that included intrusions, distractions, discrepancy detections, and breaks. The four-factor structure was reduced to a 12-item measure in Study 1 (N = 317) and confirmed in a diverse sample of employees in Study 2 (N = 160).
