PROM – Patient Reported Outcome Measures

SPRISM - Innovation in Patient Reported Outcome Measures 

Mobi Publishing is at the forefront of of innovation in Patient Reported Outcome Measures (PROMs) tool to support consultations and clinical trials. Our main toolsets are based on the Pictorial Representation of Illness and Self Measure (PRISM) PROM, a tried and tested visual tool that has been used and validated in over 50 studies. Mobi's innovation involved simple to use electronic versions that incorporate powerful psychometrics and data analytics to inform patients and clinicians in managing chronic conditions.

  • Pictorial Representation of Illness and Self Measure (PRISM) is a simple but powerful Patient Reported Outcome Measure (PROM) tool for measuring the illness burden of patients with chronic conditions
  • Easy for patients to use and some studies show it is more sensitive for capturing wellbeing elements than other Quality of Life PROMs based on Likert scales
  • The electronic version, SurveyPRISM (SPRISM), has gone through further validation activity by applying an Shneiderman’s 'Eight Golden Rules of Interface Design' analysis and further psychometric foundations evaluation
  • SPRISM addresses the inherent assumption biases in Likert based instruments (assumed stochastic relationship between elements and assumed linear relationship within well being elements)
  • The ease of use of SPRISM makes it suitable for capturing patients’ wellbeing and illness burden throughout treatment activity (e.g. before and after dialysis or morning and evenings), rather than just at the start and/or end of a set of consultations
  • SPRISM captures response psychometrics which can represent more sensitivity in patients responses
  • The analytics in SPRISM can also identify when patients’ responses change significantly, perhaps indicating a change in condition
  • The SPRISM system can collate together responses for cohorts of patients and provide sophisticated data analytics

If you would like further details about SPRISM, a copy of our White Paper (Innovation in PROMs: Pictorial Representation of Illness and Self Measure), or a copy of our forthcoming papers to be presented at the 'PROMs 2021 conference' later in the year, or to discuss using SPRISM for you patients or study then please contact Dr Carl Adams at

Our work includes collaboration with Dr Robert Lewis, Consultant Nephrologist at Wessex Kidney Centre, on developing a version for Chronic Kidney Disease patients, to complement and replace the dominant KDQOL-36™ instrument.
