A Guide to Assessing Measurement Reliability and Validity
This 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 foc
NOTE: This course will be delivered in hybrid mode, i.e. the in-person lecture will be transmitted live on zoom. The face-to-face part of the hybrid courses will go ahead conditional on at least 5 participants registering for this mode of delivery. Few classes may be delivered exclusively online, so please check under the Future dates tab for clarification. The online part of the class will be supported by its own dedicated teaching staff (along with the lead lecturer), therefore participants can expect the same level of group and individual support as the face-to-face class. You will be able to choose your preferred mode of attendance (face-to-face or online) during registration.
Additionally, we now offer this as a self-paced, online course that you can register for and start at any time. Click below under the 'Online/Self-Paced Materials' tab to register and gain access.

- 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

Feedback
"Excellent course - reinforced self-learning. I liked the fact it wasn't software dependent - e.g. not 'Reliability using R' - but they still provided code for the major statistical packages. It was obvious that the lecturer had excellent knowledge on the subject. It was the first time that I had attended one of the CASC courses, and I wouldn't hesitate to attend one again."
"I really enjoyed the course as it was very well taught and presented"
"Really good presenter, clear slides and well-paced day. The content was very useful, but I had specific questions about this topic before I came and the presenter found time to answer them, which I really appreciated"
"Very useful course, presented clearly and coherently"
"I thought the presentation style was great and the content pitched appropriately."
