Abstract
The aim of this work was to analyse the psychometric properties of the semantics and pragmatics modules of the Objective and Criterial Language Battery (BLOC). For the semantics module (n= 259), Cronbach's alpha was 0.84; for the pragmatics module (n= 142), Cronbach's alpha was 0.91. A Categoric Principal Components Analysis (CAPCAT), produced unidimentional solutions, explaining 41.65% of the variance in the semantics module, and 41.77% in the pragmatics module. We did not find differences in performance by sex. By socio-economic status, lower status children performed worse than those of middle and higher status, but only in the semantics module. Differences by age were small, with both modules producing between 3 and 4 homogeneous groups with substantial overlap. Lack of discrimination is probably related to reduced variability due to low performance in the Chilean samples. Compared to Spain, medians in the semantics module were lower than expected (though medians in the pragmatics module were slightly higher).
