Abstract

A feeling of emptiness is considered by the DSM-5 only as a symptom of BPD, despite evidence from clinical work and literature suggest that the feeling of emptiness is a transdiagnostic construct. However, few works have been made mainly due to the paucity of assessment methods. This work aims to present a) the validation of the Italian version of the Subjective Emptiness Scale (SES-I), a recent self-report for the assessment feelings of emptiness; b) the construction of a modified version of the SES, the Modified Subjective Emptiness Scale (M-SES-I) and its preliminary application in a non-clinical sample In the first studies, a total of 111 participants were divided in a clinical (n=63, M=44.13, SD=12.49) and non-clinical sample (n=48, M=34.13, SD= 11.48). Along with SES-I, participants from both groups completed the PID-5, MCMI-III, SITBQ-NS and the BDI-II. A principal component analysis (PCA) was used to investigate the structure of the SES-I, Mann-Whitney’s U was used to test the difference between groups, validity was examinate with Spearman’s Rho correlations between clinical variables. Reliability was tested with Chronbach’s alpha and MIIC. PCA shows a unidimensional structure. Clinical group has significantly higher scores on SES compared to non-clinical group. Validity and reliability were adequate. The SES-I is a valid and reliable instrument for assessing a feeling of emptiness as transdiagnostic construct. The research shows some limits: firstly, the sample size was too little and there was high diagnostic heterogeneity in clinical group, secondly, results shows that the unidimensional structure seems to be inadequate to measure the whole construct. To overcome this second limit, a modified version of the SES was proposed. The M-SES-I was preliminary tested in a non-clinical sample (n=88, M=31.66, SD=7.78). ESEM model confirm the hypothesis that the instrument was composed by three factors that measure different components of the experience of emptiness. Preliminary results show that a 18 item version of the M-SES-I was valid ad reliable in non-clinical population.
