Validating short versions of psychometric measures

This project aims to identify the most optimal, concise, and valid assessments of several individual difference variables. These include one's experiences with eating disorders, body dysmorphia, psychological distress, anxiety, depression, grit, and emotion regulation. We will rely on two steps to achieve our aim: 1.) Use statistical analyses to explore whether it is possible to shorten existing scales in a manner that does not compromise their validity and reliability. 2.) Compare the psychometric properties of various existing measures developed to identify the same construct, as well the correlations among these, in order to better understand which of the existing scales may prove most useful among the general (rather than clinical) population.
