Researchers from Hearing Sciences – Scottish Section and the Royal Hospital for Children in Glasgow have updated and improved the widely used Glasgow Benefit Inventory (GBI) and Glasgow Children’s Benefit Inventory (GCBI) for better assessment of benefit from intervention.
The Glasgow Benefit Inventory (GBI) and Glasgow Children’s Benefit Inventory (GCBI)were designed to be patient-reported questionnaires administered after an intervention such as surgery, without the need for any pre-treatment measurement. They have proved to be very popular, having been used in a large number of studies and translated into many languages. Both scales avoid the use of disease-specific language and are therefore suitable for use in a wide variety of disciplines.
Following analysis of large datasets, researchers from University of Nottingham Hearing Sciences – Scottish Section and the Royal Hospital for Children in Glasgow have updated the subscale scoring systems for both the GBI and the GCBI. The additional subscales generated by the shortened GBI (renamed GBI-5F) provide more information about the benefit of interventions than was previously available. The new 4 factor subscale scoring system for the GCBI can reveal much more about how specific treatments benefit certain aspects of children’s wellbeing.
Both publications include improved guidelines for how to calculate and present the results, which will be of value both to researchers and to those using the instruments for routine audit purposes.
