title: [Validation of the questionnaire for adolescents concerning ailments of lumbosacral region. Part II: reliability of questions about risk factors].
abstract: The second part of the series of articles presents the reliability testing results of questions concerning factors that could influence or originate the symptoms of low back pain (LBP). The questions are a part of the questionnaire designed for pupils aged 13-18. 124 persons aged 13-17 were tested. The questionannaires were filled in twice by every pupil in no more than 7-day period, and then the answers were compared according to the test-retest method. The questions concerning risk factors were about: the intensive growth period, chronic diseases, the medical diagnosis of LBP, concomitant faulty posture, sport training and leisure time physical activities, leisure time spent sitting, possible nutritional deficiencies, the amount of sleep, the impact of lifting and dislike for school. Results that were obtained in the process of testing indicated that reasoning would be invalid if based on questions about sports (45% repeatable answers), about leisure time physical activities (Polish version of the leisure time exercise questionnaire of Godin and Shepard--correlation for the Godin and Shepard index was 0,29) and about intensive growth period (small number of valid responses indicates that the question is incomprehensible for adolescents). The rest of questions were found acceptably reliable.
