"Don't throw the baby out with the bathwater!'' Interpersonal strain at work and burnout

Interpersonal strain represents the feeling of discomfort and disengagement in the relationships with people at work resulting from exceeding social requests and pressures. This article has three aims: (1) to introduce the Interpersonal Strain at Work scale (ISW), (2) to examine its construct validity and reliability, and its relationship with the Maslach Burnout Inventory exhaustion and cynicism; and (3) to test the generalizability of the ISW across different work settings. Multilevel CFA on two samples of call centre agents (5407) and hospital professionals (753), nested in 191 and 43 units, respectively, confirmed the good psychometric properties of the ISW and its distinctiveness from established burnout dimensions. The generalizability of ISW was also supported. Interpersonal strain at work seems to be a promising construct to recapture the interpersonal nature of the burnout syndrome that was lost when the concept of burnout was extended beyond the human services.
