Abstract. The Structured Interview for Hoarding Disorder (SIHD) is a semi-structured interview designed to assist clinicians in diagnosing a hoarding disorder (HD). This study aimed to validate the Italian version of the SIHD. For this purpose, its inter-rater reliability has been analyzed as well as its ability to differentiate HD from other disorders often comorbid. The sample was composed of 74 inpatients who had been diagnosed within their clinical environment: 9 with HD, 11 with obsessive-compulsive disorder (OCD) and HD, 22 with OCD, 19 with major depressive disorder (MDD), and 13 with schizophrenia spectrum disorders (SSD). The results obtained indicated “substantial” or “perfect” inter-rater reliability for all the core HD criteria, HD diagnosis, and specifiers. The SIHD differentiated between subjects suffering from and not suffering from a HD. Finally, the results indicated “good” convergent validity and high scores were shown in terms of both sensitivity and specificity for HD diagnosis. Altogether, the SIHD represents a useful instrument for evaluating the presence of HD and is a helpful tool for the clinician during the diagnostic process.
