Psychometrics & Measurement Lab

About the Group

Welcome to the Psychometrics & Measurement Lab. Our aim is to bring together the array of contributions the Institute of Psychiatry, Psychology & Neuroscience has made to the field and further promote research. Here, you will find resources such as the IOPPN Psychometrics & Measurment Database, information about our local psychometric community, upcoming events such as courses, seminars and talks, and a collection of useful material. 

These webpages represent independent research part funded by the National Institute for Health Research (NIHR) Biomedical Research Centre at South London and Maudsley NHS Foundation Trust and King’s College London. The views expressed are not necessarily those of the NHS, the NIHR or the Department of Health. 


IoPPN Psychometrics and Measurement Database 

The Psychometrics and Measurement Lab is constantly updating a database of publications regarding psychometrics and measurement, where at least one of the authors is affiliated with the IOPPN. Our aim is to bring together the array of contributions the Institute has made to the field and further promote research. 

A corresponding web-application is currently developed, containing ~150 measures covering most aspects of mental health research. 

If you have developed a measure which could be included in the database, please contact Silia Vitoratou. 

The Psychometrics and Measurement Lab is involved in organising a group for KCL researchers and students working on psychometrics, our local Psychometrics Community. If you are affiliated with the College and your research involves psychometrics (developing PROMs or PREMs or other psychometric scales, applying or developing latent variable models and relevant software), or in general you are interested in the field, you could join this community by enrolling to our webpage on KEATS. 

Advisory Service: 

The PML provides a Psychometrics Advisory Service to staff and students, from all IoPPN departments free of charge. This service is intended to provide initial project advice and technical support with carrying out a research project. Statistical support is provided in the following areas: 

  • Developing a psychometric scale 
  • Item response theory models 
  • Exploratory and Confirmatory factor analysis 
  • Reliability and Validity Assessment 
  • Measurement invariance (multiple groups, multiple conditions) 
  • Interpretation and presentation of results 
  • Queries by statistical referees 
  • Statistical software (SPSS, Stata, Amos, R, Mplus) 

All students planning a research project are encouraged to seek the advice of its academic staff.  Permission must be obtained by MSc students from their project supervisors to attend this service. MSc Students are limited to two 30 min appointments for the academic year.  PhD/Staff are limited to three 30 min appointments a year, which may be booked in succession, if a longer appointment than 30 mins is required. All bookings must be made at least 48hrs in advance. During busy periods, you may have to wait 2-3 weeks for an appointment.  The Biostatistics and Health Informatics Department will not provide last minute assistance.  

Terms and conditions: Failure to attend the Advisory Service without sufficient notice, (2 working days) or a valid reason, will render you ineligible for future appointments with our Advisory Service.
