The second is to evaluate the performance of the ant colony optimization procedure and discuss the applicability of the ant colony optimization procedure in creating a short form. Results revealed…

Perfectionism measures developed in English-speaking populations have become frequently used in many non-English contexts, including in Italy. Establishing structural and measurement equivalence of instruments between Canadian and Italian samples is therefore important in establishing the validity of these concepts and instruments in Italian…

Perfectionism is a multidimensional personality trait with two higher-order dimensions; perfectionistic strivings and perfectionistic concerns.

The CAPS-SF consists of a…
