Abstract
Researchers have studied loneliness as a modern health epidemic which is associated with myriad negative health effects, yet the literature lacks evidence of loneliness' correlates, including incivility, in the workplace. This paper not only replicates previous work on incivility, a pervasive interpersonal workplace stressor, it also contributes novel findings on the relative importance of loneliness in explaining variance in occupational health outcomes. We tested hypotheses using two cross-sectional datasets containing data from the general working population (Sample 1) and state corrections supervisors (Sample 2). Through relative importance analyses, including relative weights analysis, we found that both general and workplace loneliness explain substantial variance in several outcomes (e.g., emotional exhaustion, depression symptoms, and turnover intentions) relative to the variance explained by workplace incivility. When controlling for perceived work stress, general loneliness appears to be more important than incivility in explaining variance in emotional exhaustion, job satisfaction, and depression symptoms.
