Adaptation of the ZKPQ-50-CC Scale to the Uruguayan Population

The Zuckerman–Kuhlman Personality Questionnaire (ZKPQ) is a personality assessment instrument that evaluates five personality traits considered to reflect temperament dimensions (Aluja et al., 2006). This personality framework is commonly referred to as the “Alternative Five-Factor Model.”
The present study reports the results of the adaptation of this questionnaire for the Uruguayan population. The procedures proposed by Hambleton & Patsula (1999) were followed. Given the existence of an adaptation of the ZKPQ-50-CC for the Argentine population (Póo et al., 2013), a country with strong cultural similarities to Uruguay, it was not necessary to carry out a linguistic adaptation of the items.
A pilot study was conducted using a convenience sample (N = 151), followed by administration to a nationally representative sample selected through quota sampling by sex and age (N = 1,961; 910 men and 1,051 women, mean age 44.76 (17.62).
An ad hoc sociodemographic questionnaire was administered, along with the following instruments: the Socioeconomic Level Index (INSE (CINVE, 2012), SA-45 (Sandín et al., 2008), NEO-FFI (Costa & McCrae, 2008), TCI-140 (Selma et al., 2017), ZKPQ-50-CC (Póo et al., 2013) and SWL (Atienza et al., 2000).
Factorial structure analyses yielded mostly acceptable fit indices. Subsequently, descriptive statistics, reliability estimates (α Kr), and sex differences were calculated for the five scales (Table 1).
Means, standard deviations, and reliability coefficients (Cronbach’s alpha) for the total sample, as well as for women and men separately. Statistical significance levels for Mann–Whitney U tests comparing sexes are also reported (values in bold indicate p < .01).
Finally, normative data (means, standard deviations, and percentiles) are provided for men and women across five age groups (18–24, 25–30, 31–45, 46–60, and 61+).
It is concluded that the model fit indices are adequate, and that the quality of the sample and the specificity of the normative data will facilitate the use of the ZKPQ-50-CC in countries within the region.
