Abstract: Introduction: The Intolerance of Uncertainty Scale-Short Version (IUS-12) is a measure of trait intolerance of uncertainty. Objective: The purpose of the present study was to conduct a cross-cultural adaptation of the IUS-12 for use in Brazil and to investigate the scale's psychometric properties. Methods: The research was conducted via an online research platform with a sample (n = 704; 80.1% female and 19.9% male) from different states in all five regions of Brazil. Participants were adults between 18 and 59… Show more

“…Prospective IU (seven items) and Inhibitory IU (five items). The validation study in Brazil evidenced a two-factor structure with high correlation between them (0.83) [39], which can indicate the existence of a higher order factor (intolerance to uncertainty) [16,40]. The literature published to the present day indicates diverse evidence of the one-factor solution of intolerance to uncertainty, as well as the use of its overall score [41,42].…”

“…The levels were categorized as low (from zero to 13 points), moderate (from 14 to 26 points) and high (27 points or more) [36]. d) Level of intolerance to uncertainty: the Intolerance of Uncertainty Scale (IUS) [37], 12item version (IUS-12) [12], cross-culturally adapted [38] and validated for use in the Brazilian population [39] was applied. The items contain answer options arranged in a Likert scale, varying from one (not at all characteristics) to five (very characteristic) and assessing two dimensions:…”

“…(d) Level of intolerance to uncertainty: the Intolerance of Uncertainty Scale (IUS) [ 51 ], 12-item version (IUS-12) [ 52 ], cross-culturally adapted [ 53 ] and validated for use in the Brazilian population [ 54 ], was applied. The items contain answer options arranged in a Likert scale, varying from one (not at all characteristics) to five (very characteristic) and assessing two dimensions: prospective IU (seven items) and inhibitory IU (five items).…”

“…We planned to use standard deviation cut-off criteria to split our sample, however, even with one standard deviation above and below the mean we found extremely uneven group sizes which limits the ability to make accurate network comparisons. Therefore, we conducted a median split on the samples, representing high and low intolerance of uncertainty, with scores falling exactly at the median (35 on our IUS-12 measure and similar to previous studies e.g., Kretzmann & Gauer, 2020) being included in the high group. See Table S13 for sample sizes for each sub-group.…”
