INTRODUCTION: Differential rater function over time (DRIFT) and contrast effects (examiners' scores biased away from the standard of preceding performances) both challenge the fairness of scoring in Objective Structured Clinical Exams (OSCEs). This i... Read More about Determining influence, interaction and causality of Contrast and Sequence effects in OSCEs..

Combining expert judgment and psychometric information to create the Global Scale for Early Development (GSED). Paper presented at Proceedings of the Patient Reported Outcome Measures (PROMs) Research Conference, Sheffield, UK

Background: The Global Scale for Early Development (GSED) a global and culturally neutral measure of child development under 3 years of age is designed to allow comparisons within and across countries. The project has been undertaken by an experience... Read More about Combining expert judgment and psychometric information to create the Global Scale for Early Development (GSED).

Validation of the Infant and Young Child Development (IYCD) Indicators in Three Countries: Brazil, Malawi and Pakistan (2021)
Journal Article
Gladstone, M., Lancaster, G., McCray, G., Cavallera, V., Alves, C. R., Maliwichi, L., …Kariger, P. (2021). Validation of the Infant and Young Child Development (IYCD) Indicators in Three Countries: Brazil, Malawi and Pakistan. International Journal of Environmental Research and Public Health, 18(11), 1 - 19. https://doi.org/10.3390/ijerph18116117

Background: The early childhood years provide an important window of opportunity to build strong foundations for future development. One impediment to global progress is a lack of population-based measurement tools to provide reliable estimates of de...

Measuring the Effect of Examiner Variability in a Multiple-Circuit Objective Structured Clinical Examination (OSCE) (2021)
Journal Article
Yeates, P., Moult, A., Cope, N., McCray, G., Xilas, E., Lovelock, T., …McKinley, R. K. (. (2021). Measuring the Effect of Examiner Variability in a Multiple-Circuit Objective Structured Clinical Examination (OSCE). Academic Medicine, 96(8), 1189-1196. https://doi.org/10.1097/acm.0000000000004028

Purpose Ensuring that examiners in different parallel circuits of objective structured clinical examinations (OSCEs) judge to the same standard is critical to the chain of validity. Recent work suggests examiner-cohort (i.e., the particular group of...

Determining sample size for progression criteria for pragmatic pilot RCTs: the hypothesis test strikes back! (2021)
Journal Article
Lewis, M., Bromley, K., Sutton, C., McCray, G., Myers, H., & Lancaster, G. (2021). Determining sample size for progression criteria for pragmatic pilot RCTs: the hypothesis test strikes back!. Pilot and Feasibility Studies, 7, Article 40. https://doi.org/10.1186/s40814-021-00770-x

BACKGROUND: The current CONSORT guidelines for reporting pilot trials do not recommend hypothesis testing of clinical outcomes on the basis that a pilot trial is under-powered to detect such differences and this is the aim of the main trial. It state... Read More about Determining sample size for progression criteria for pragmatic pilot RCTs: the hypothesis test strikes back!.
