The validity of a rheumatoid arthritis medical records-based index of severity compared with the DAS28

Outcome measures play an extremely important role in clinical trials and observational research. Outcome measures for rheumatoid arthritis cover a whole array of domains, ranging from measures describing the inflammatory process to measures describing the ultimate consequences of long-term disease, such as joint damage, physical function and quality of life. There is a scientific need to be able to quantify what is called the 'severity of rheumatoid arthritis', so that patients with rheumatoid arthritis can be clustered according to their propensity to develop an unfavourable outcome. It is a challenge to find an appropriate measure for severity. One attempt has been the development of the Rheumatoid Arthritis Medical Record-Based Index of Severity. This commentary elaborates on how such a measure of severity should be validated to determine whether it is appropriate for practical use

Employability and Social Innovation:The Importance of and Interplay between Transformational Leadership and Personality

Purpose — The purpose of this chapter is to draw attention to employability beingan important social innovation that potentially thrives with transformational leadership, partly depending on certain personal characteristics such as managerialrole and personality.Methodology/approach — The study was carried out among pairs of employees(314) and immediate supervisors (334) working at a large Dutch company that produces building materials. We made use of Linear Regression and StructuralEquation Modeling to test our hypothesis and explore our assumptions with regardto the research model.Findings — We have found that transformational leadership is positively related toemployee and supervisor ratings of employability. Furthermore, there is some indication that transformational leadership enhances employability in some situations,demonstrating differences between categories of workers with and without a managerial function. Moreover, it appeared that after controlling for personality, onlythe positive relationship between transformational leadership and supervisor ratings of employability, remained for the workers not having a managerial function.Research limitations/implications — Our study design comprised a cross-sectionalapproach and therefore future longitudinal research is necessary to investigatecausal relationships between transformational leadership, personality, andemployability.Practical implications — In terms of individual career development practices, ouroutcomes should be translated into increased attention for aligning leadership styleto meet the requirements of all types of employees across the life-span.Social implications — By providing more insight into the increased importance oftransformational leadership for certain groups of workers, this contribution isintended to come up with opportunities for increasing the employability for differenttypes of workers.Originality/value — This chapter draws attention to the fact that transformationalleadership can be a useful tool for stimulating employability of workers. Workercharacteristics such as personality, work role (e.g., managerial role) and other lifespanfactors always have to be taken into account for a customized approach, giventhe uniqueness of each and every employee.</div
