Professional Biography

Dr. Paul McDermott is a Professor in the Quantitative Methods Division at Penn GSE. A psychometrician and quantitative psychologist, he previously served as director of Clinical and Industrial Measurement for The Psychological Corporation and holds Diplomate from the American Academy of Assessment Psychology. Dr. McDermott is also a licensed psychologist and certified school psychologist.

Dr. McDermott specializes in measurement theory, test construction, applied multivariate statistics, and multilevel and longitudinal modeling. He develops standardized measures of school behavioral adjustment, classroom learning behaviors, neighborhood effects, addiction severity, pain, and cognitive growth. Recent nationally standardized measures include the Adjustment Scales for Early Transition in Schooling, the Adjustment Scales for Children and Adolescents, the Learning Behaviors Scale, and the Preschool Learning Behaviors Scale. All of these instruments have been translated into numerous languages and are applied worldwide. Dr. McDermott co-authored the Adjustment Scales for Preschool Intervention, which is designed for Head Start populations. 

Research Interests and Current Projects

Dr. McDermott is co-principal investigator for a large-scale Spanish/English translation and equating study assessing classroom behavioral disorders via the Adjustment Scales for Preschool Intervention, supported by the U.S. Department of Education, Institute of Education Sciences. This work applies item response theory (IRT) and other advanced psychometric procedures to develop linguistically and culturally appropriate measures with bilingual preschool teachers and diverse Latino populations in Miami. 

Dr. McDermott also supervises a Penn research group that is scaling and validating several measures of classroom learning behavior as well as school and home assessments of youth social-emotional adjustment in Trinidad and Tobago. These measures are nationally standardized across the islands as supported by the Ministry of Education. Funded by the National Institute of Child Health and Human Development, Dr. McDermott directed development of the Learning Express, an individually administered adaptive performance battery for measuring preschool learning growth over brief intervals as grounded in IRT, and the Learning-To-Learn Scales to assess differential learning styles related to strategic planning in learning, persistence, appropriate risk-taking, attentiveness, and interpersonal responsiveness in learning situations.
