IJERPH, Vol. 17, Pages 2211: Tapping the Employee Perspective on the Improvement of Sustainable Employability (SE): Validation of the MAastricht Instrument for SE (MAISE-NL) (International Journal of Environmental Research and Public Health)

Background: Sustainable employability (SE) is top priority for employers. Measures based on the employee perspective of SE that would give direction to interventions to be initiated by employers currently fall short. This study aims to develop and validate an instrument that captures these issues: the MAastricht Instrument for Sustainable Employability (MAISE). Methods: MAISE items were generated from an extensive literature review and interviews with employers and employees. A questionnaire containing these items as well as proxy variables (health and vitality) and demographics was answered online by 632 employees (response rate 50.3%). Construct validity, reliability, and criterion validity were tested through Principal Component Analysis (PCA), Confirmatory Factor Analysis (CFA), Cronbach’s alpha, and correlational analyses. Results: The MAISE comprises 12 scales divided over five areas: (1) Meaning of SE; (2) Level of SE; (3) Factors affecting my SE; (4) Overall responsibility for SE; and (5) Responsibility for factors affecting my SE. Reliability, construct, and criterion validity were adequate to good. SE of the employees was relatively high, and SE was considered a shared responsibility of the employee and employer. Conclusions: This study showed the MAISE to be reliable and valid in various employee groups. More validation studies are needed. We recommend that employers use the MAISE as a needs assessment in order to develop SE interventions that will be readily accepted.
