Measuring the impact of an organizational intervention on absence of employees with disabilities: A quasi-experimental design 157 (4), 723-742

This article presents research on an organizational inclusion programme aiming to reduce absenteeism due to illness and injury among employees with dis-abilities. Qualitative fieldwork on the programme's characteristics was followed by a quasi-experimental design with two control groups (non-equivalent and no-treatment) using abbreviated time series (2005-12). The data of employees with disabilities who participated in the programme were compared with those of non-participants and of employees without disabilities, through a hierarchical non-nested negative binomial regression with a lagged outcome variable. The authors find strong evidence of a reduction in absence due to illness among participant employees with disabilities, and somewhat weaker evidence of reduced absence due to injury.
