Hi everyone, I have a question. I am conducting a quantitative study for a competency project. I'm interested in using Rotter's Locus of Control scale to study the impact of racial/ethnic identity, athletic identity, and locus of control on social justice movements within collegiate athletics. Rotter has passed away and the person whose contact information is linked with the scale is no longer working. How would I obtain permission to use his scale? Or do you have suggestions for other locus of control scales that could be used for my study? Thank you!
