The "test-retest" method was used, the questionannaires being filled in twice by every pupil in no more than 7-day period. Questions were asked about LBP, the accompanying ailments, the intensity of pain, the length of the episode, the cause of the beginning, the constant pain, the activities that worsen or reduce symptoms, the necessity of therapy, the presence of functional disorders connected with LBP, height, weight and basic ,,red flags" which could indicate pain of specific origin. Results that were obtained in the process of testing indicated that reasoning was invalid when based on questions about the length of episode (60% repeatable, rank correlation 0.3) and on questions about activities that worsen or reduce pain (respectively 34 i 35% repeatable answers).
