Brief Summary

The purpose of this study is to explore the reliability of a new evolutionarily-informed model for conceptualizing personality pathology. In a preliminary phase prior to the present study we investigated reliability by comparing how therapist pairs conceptualized and assessed the same patient and how therapists and patients assessed the acceptability of the model. In this new study we want to confirm that the validity data initially collected are valid across cultures and nations. Therefore, psychology students (n=110) from 5 countries (China, Italy, Poland, Spain, United States) will participate in a specific training on the model and then apply the model on transcripts of the first two sessions and on assessment reports and two supervisors will evaluate the inter-rater reliability and acceptability in using the model on the same patients.

Outcome Measures

Primary Outcomes (1)

Cross-cultural inter-rater reliabilitt
Inter-rater reliability of adherence to the case conceptualization within any single group will be compared with the Italian group where the diagnostic procedure was initially validated to confirm that there are no differences in reliability between Italian group and the other groups. Inter-rater reliability will be scored as kappa values and intraclass correlation coefficients.
From the enrollment to the end of the end of the diagnostic procedure that last 1 hours and will be performed within 1 month from the recruitment.
