de Korte, E.M. (author), Wiezer, N. (author), Hanssen, J.H. (author), Vink, P. (author), Kraaij, W. (author)Background: To improve workers’ health and well-being, workplace interventions have been developed, but utilization and reach are unsatisfactory, and effects are small. In recent years, new approaches such as mobile health (mHealth) apps are being developed, but the evidence base is poor. Research is needed to examine its potential and to assess...article 2018

Schmettow, M. (author), Vos, W. (author), Schraagen, J.M. (author)Usability testing is recognized as an effective means to improve the usability of medical devices and prevent harm for patients and users. Effectiveness of problem discovery in usability testing strongly depends on size and representativeness of the sample. We introduce the late control strategy, which is to continuously monitor effectiveness of...article 2013
