The aim of the study was to determine the effect of temperament on stressors' appraisal, emotional dystress and health costs of stress transaction. 289 secondary school students (93 males and 196 females) were investigated. The Profile of Mood States (POMS) by McNair, Lorr and Droppleman and the inventory concerning daily hassles and common somatic symptoms developed by author were used. In the course of two school years eight measurements were done. Temperament traits were assessed by FCZ-KT by Strelau and Zawadzki. The results of UNIANOVA indicated that: (1) More persevering students assessed stress caused by daily hassles higher and showed worse mood than their less persevering colleagues. (2) In more emotionally reactive adolescents the intensity of stress was a little higher. They reported somatic symptoms and experienced negative mood states more frequently. (3) The level of positive mood states was higher in students, who were more brisk, active and persistant. (4) Girls assessed the intensity of daily hassles' stress as well as the frequency of somatic symptoms higher than boys and their mood was more negative.
