The article describes results of a study on the factor structure of a further Italian adaptation of the Perceived Stigma Scale in Inflammatory Bowel Disease (PSS-IBD). The scale consists of 10 items measuring general perceived stigmatization that can be declined in 5 domains of life. The translated scale was administered to a sample of 162 patients who were affected by ulcerative colitis or Crohn’s disease. Explorative and confirmatory bi-factor analysis revealed that the scale adequately measured one single dimension of stigma along with 5 domain-specific scores. Perceived stigma was generally low, albeit about 20% of the sample reported moderate to strong levels stigma, especially in the domain of friendship and workplace. Levels of general stigma were influenced neither by type of disease nor by gender, although women reported higher stigmatization in the household context than men. Moreover, stigma was negatively correlated with resilience and self-esteem, thus supporting the validity of the scale. In sum, the present results seem to confirm the hypothesis that the PSS-IBD Italian version (IV) is a reliable and valid instrument to measure perceived stigma in patients with IBD. By virtue of its reduced length, PSS-IBD also appears to be an instrument that can easily be administered in diverse contexts.

Questo articolo descrive i risultati di uno studio sulla struttura fattoriale di un ulteriore adattamento al contesto italiano della Perceived Stigma Scale in Inflammatory Bowel Disease (PSS-IBD). La scala è composta da 10 item che forniscono una misura generale di stigma per-cepito a sua volta declinata in 5 specifici domini di vita. La scala tradotta è stata somministrata a un campione di 162 partecipanti affetti da colite ulcerosa o dal morbo di Crohn. Le analisi bi-fattoriali esplorative e confermative hanno evidenziato che la scala misura adeguatamente una singola dimensione di stigma insieme a 5 punteggi specifici per ciascun dominio. Lo stigma percepito era generalmente basso, sebbene circa il 20% dei partecipanti abbia riportato un livel-lo di stigma da moderato a forte, in particolar modo nei contesti amicali e di lavoro. I livelli generali di stigmatizzazione non appaiono essere influenzati dal tipo di malattia né dal genere dei partecipanti, sebbene le donne riportino maggiore stigmatizzazione nei contesti domestici rispetto agli uomini. Inoltre, lo stigma è apparso correlato negativamente con la resilienza e l’autostima, supportando così la validità della scala. In sintesi, i risultati sembrano indicare che la versione italiana della PSS-IBD-Iv sia uno strumento valido e affidabile per misurare lo stigma percepito da pazienti con IBD. In virtù della sua brevità, il PSS-IBD sembra anche es-sere uno strumento facile da somministrare in diversi contesti.
