The Pavlovian Temperament Survey - PTS was developed to evaluate the behavioral expression of Central Nervous System properties. This study aimed to begin the assessment process and reduction of PTS's items, version 7 to 14 years. A sample of 124 subject aged 7 to 14, of both sexes, who had their temperamental characteristics evaluated for PTS took part in the study. The reduction process and assessment consisted of two stages: analysis of the correlation total item and exploratory factorial analysis. The results pointed to the permanence of 107 items of the total of 252 that initially composed the scale: 35 items in FE (38,8%), 42 in FI (50%) and 30 in MO (38,4%). New studies are necessary for a better adaptation of the items to the Brazilian context, with extension of the sample to give continuity to the assessment process and reduction of PTS's items version 7 to 14 years.
