PSYCHOMETRIC PROPRIETIES OF THE ITALIAN VER- SION OF THE PERSISTENT COMPLEX BEREAVEMENT INVENTORY

Abstract

The study aims to evaluate the psychometric properties of the Italian version of the Persistent Complex Bereavement Inventory (PCBI) in a sample of 318 community – dwelling adults. We investigated the factor structure, convergent and nomological network validity of the PCBI, considering the associations with aspects theoretically related to PCBI and adult attachment style. Our confirmative factor analysis supported a three-factor model. However, the bifactor model suggested the scale structure is unidimensional. Moreover, the PCBI showed a positive and significant correlation with the Inventory of Complicated Grief scale, supporting its convergent validity. Considering the nomological network validity, PCBI was associated with the closeness to the deceased and the circumstance of death. The attachment style of bereaved individuals was characterized by Discomfort with Closeness and Preoccupa- tion with Relationships. Our findings suggest that the Italian translation of the PCBI may rep- resent a reliable instrument and support its convergent and nomological network validity.
