Web2 days ago · Internal consistency was assessed with Cronbach's alpha. Concurrent and convergent validity were explored via correlations with the PEM-CY. Further psychometrics were examined using a Rasch model. WebCronbach's alpha is the correlation between the answers in a questionnaire. Like the correlation coefficient, Cronbach's alpha can take on values between -1 and 1. The internal consistency of a test is greater the greater the correlation between items on average.
