Popis: To evaluate the validity and reliability of the Child Perceptions Questionnaire 11–14 (CPQ11-14) for children attending public educational institutions in Floridablanca (Colombia). An evaluation study of diagnostic technology was conducted. The questionnaire was completed by 500 students aged 11–14 years who were selected by simple random sampling. The test–retest reproducibility was evaluated in 36 students chosen at random from one of the schools; the questionnaire was completed a second time by these students, with an interval of two weeks between administrations. Internal consistency was estimated using the Cronbach’s alpha coefficient, and test–retest reproducibility was determined with the intraclass correlation coefficient (ICC). The Rasch Rating Scale Model was used to perform the validation; the structure of the categories, the quality of the items, the invariance and the one-dimensionality were analyzed; invariance was confirmed using differential item functioning (DIF). Informed consent was obtained from the parents or guardians, and assent was obtained from the minors. The mean age was 12.7 ± 1.1 years, and 210 (42.0%) participants were female. The Cronbach's alpha and ICC values were 0.91 and 0.63, respectively. The 37 items fit the Rasch model, but a uniform DIF was observed for an item that was eliminated. The questionnaire was not one-dimensional, and the proportion of variance explained by the model was poor (26.3%). The CPQ11-14 showed unsatisfactory test–retest reproducibility and excellent internal consistency; no unidimensionality was observed, but the items fit the Rasch model.
