The psychometric lab works on statistics, epidemiology and research epistemology. Its focus is on the assessment of human behaviors and perceptions with extensive application of Rasch statistical modeling, and it is at the forefront of research on the “outcome” of rehabilitation at the person-environment interface. The Lab is mostly engaged in the development of new quantitative questionnaires and runs data analysis within psychometric, epidemiological and cost-effectiveness studies related to disability and rehabilitation. It also works on methodological (e.g., variable construction, trial design) and ethical issues (e.g. evaluating Quality of Life) involving Rehabilitation Medicine.


Cutting edge/hot topic:

Development and validation of outcome scales. Web-based linearization and quality check of raw questionnaire scores, though server-based, “back-stage” Rasch analysis.
