Hi there, my name is Richard, I am from the UK. My background is largely in psychology. I did a BSc (sports science) MSc (health psychology) and a PhD (cognitive neuropsychology) at the University of Leeds from 2001-2010. I am very experienced at working with and designing a range of psychometric and cognitive testing. I can talk about concepts such as factor analysis, internal validity and reliability. The most important factor is designing the questions in a way which provides the most powerful empirical data, such as the use of VAS instead of Likert scales, etc. If you’d like to know more please get in touch.
