This self-paced online course offers an introduction to the principles, methods of assessment, and the appropriateness of statistical analyses for different types of measurement validity and reliability. Particular focus is given to statistical assessment of reliability over time, context and rater.
The course is delivered in a self-paced format by UCL's Centre for Applied Statistics Courses (CASC), part of the UCL Great Ormond Street Institute of Child Health (ICH).
Understanding and assessing reliability and validity are important when developing and using new tests and measurement tools.
This course gives an introduction to the concepts of reliability and validity, how the two are associated, and the methods commonly used for assessing these factors in different data types and study designs. Knowledge of basic statistical concepts (e.g., p-values, confidence intervals) is beneficial for this course.
The following topics will be covered during this one-day course:
- Types of validity
- Assessing validity of numeric and categorical outcomes
- Types of reliability
- Assessing reliability for numeric outcomes
- Bland-Altman Limits of Agreement
- Intraclass Correlation
- Assessing reliability for categorical outcomes
- Internal reliability of assessment measures
At the end of the course, delegates will be in a much better position to develop, test and refine their own measurement tool relating to their own research.
Furthermore, delegates will understand the implications of using imperfect measurements and thus be more qualified to perform critical appraisal of journal articles documenting quantitative and qualitative research.
In particular, delegates will be able to:
- Understand the difference between reliability and validity of a measurement.
- Distinguish between different types of reliability and validity assessments and understand what the purpose of each is.
- Set up a reliability or validity study, with appreciation of the type of data required and other aspects of the study design.
- Perform reliability and/or validity assessments for both numeric and categoric measurements.
Course structure and teaching
This is an online, self-paced course that includes:
- Full electronic notes
- Short lecture videos (recorded outside of the classroom with screen recordings and annotation) that follow closely with the notes
- Interactive quizzes for each chapter
- Revision summaries
- Support will also be available through a forum, where you can ask questions related to the course materials.
A basic level of statistical literacy is required as a prerequisite.
It is desirable for the course participants to have basic knowledge of statistics, i.e. notion of statistical inference, p-values and Confidence intervals.
Those who have completed the five-day Introduction to Statistics and Research Methods course run frequently by the Centre for Applied Statistics Courses (CASC) team will be equipped.
