Work ability and perceived work stress

In this study, work ability was examined in a group of civil and military servants of the Netherlands Army. Work ability was assessed by using the Work Ability Index (WAI); this instrument was developed by the Finnish Institute of Occupational Health to monitor aging workers. The relationship of WAI and perceived work stress was examined using a stress questionnaire. Statistical analysis indicated negative correlations of WAI scores and several different stress factors. The most prominent relationship was observed between WAI and qualitative overload (r=−0.49). WAI scores were also negatively associated with increasing age, a finding comparable to studies with the WAI in several other countries. Absenteeism from work seems to be associated with increased perceived work stress.
