de Vet, H.C.W. (author), Mullender, M.G. (author), Eekhout, I. (author)Objective: The concept of specific agreement (SA) has been proposed for dichotomous outcomes for two or more raters. We aim to extend this concept for variables with more than two ordinal or nominal categories and more than two raters. Study Design and Setting: We used two data sets: four plastic surgeons classifying photographs after breast...article 2018

(author)OBJECTIVE:: To examine the construct validity of the Individual Work Performance Questionnaire (IWPQ). METHODS:: A total of 1424 Dutch workers from three occupational sectors (blue, pink, and white collar) participated in the study.

(author)Design/methodology/approach - After pilot-testing, the 47-item IWPQ was field-tested amongst a representative sample of 1,181 Dutch blue, pink, and white collar workers. Factor analysis was used to examine whether the four-dimensional conceptual framework could be confirmed. Rasch analysis was used to examine the functioning of the items in more...article 2013

(author)Objective: Individual work performance is differently conceptualized and operationalized in different disciplines. The aim of the current review was twofold: (1) identifying conceptual frameworks of individual work performance and (2) integrating these to reach a heuristic conceptual framework.

(author), TNO Kwaliteit van Leven (author)Background context: The recovery of patients with chronic low back pain (LBP) is slow. Furthermore, it is recently proposed that chronic LBP needs a prognostic approach to determine who will develop clinically significant back pain. Therefore, it is imperative to identify prognostic factors that are mostly seen in chronic LBP patients at an...article 2010

Methods Secondary data analysis in a cohort of 628 workers on sick-leave between 3 and 6 weeks due to low back pain (LBP). The association of a broad set of demographic, work,...article 2009

Missing data is a challenging problem in many prognostic studies. Multiple imputation (MI) accounts for imputation uncertainty that allows for adequate statistical testing. We developed and tested a methodology combining MI with bootstrapping techniques for studying prognostic variable selection. Method. In our prospective cohort...article 2007

To date, mental health problems and mental workload have been increasingly related to long-term sick leave and disability. However, there is, as yet, no structured protocol available for the identification and application of an intervention for stress-related mental health problems at the workplace.

(author), TNO Kwaliteit van Leven (author)Background: Successful management of workers on sick leave due to low back pain depends on the identification by the occupational physician of modifiable prognostic factors in the early phase of sick-leave. The prognostic value of factors which influence the course of low back pain and return to work in occupational health care is unclear....article 2006
