This investigation concerns the translation and validation of the ITC - Sense of Presence Inventory (ITC-SOPI) for
the Portuguese-speaking population (in Europe), estimating the validity of the content and concepts and the
maintenance of an equivalent semantics. It also sought to verify its psychometric properties, namely its factorial
validity and internal consistency. The sample consisted of 459 individuals, 274 males and 185 females. The
fidelity of the subscales varied between 0.67 and 0.89. Confirmatory factor analysis revealed a theoretical model
of 35 items, divided by four factors. After fixing some of the residual errors between items, the following adjustment
indexes were calculated: χ2/df = 2.301; goodness fit index = 0.860; comparative fitness
index=0.889; root mean square error of approximation=0.053; Akaike’s information criterion=1420. Based
on the observed results and the robustness of the sample size used, the obtained theoretical model shows that the
ITC-SOPI is recommended to measure presence in virtual reality research projects with samples of Portuguese
language speakers.
