An educational psychologist designed a study to evaluate the effectiveness of a new mobile application designed to reduce academic anxiety in secondary school students. 120 students who reported high levels of exam pressure were recruited. To select suitable participants, each student completed a newly developed self-report scale which scored their academic anxiety from 1 (minimal anxiety) to 50 (severe anxiety).
Students scoring between 35 and 45 were selected to participate and randomly allocated to one of three conditions:
At the end of the 6 weeks, all students completed the self-report academic anxiety scale again to compare the changes in anxiety levels.
What is meant by the term 'validity'? How could the educational psychologist have assessed the validity of the self-report scale used to measure academic anxiety?
