title: Comparison of self-administration and face-to-face interview for surveys of low back pain in adolescents.
abstract: The aim of this study was to compare self-administration with face-to-face interview in the investigation of low back pain in adolescents. Fifty-seven adolescents with low back pain (mean age 17.3 y; range 16-18) first completed a questionnaire and were then invited to an interview. Analysis included item completion, percentages of agreement and weighted kappa. Item completion rates were high and comparable between self-administration and interview. Information between both methods was analogous for severity and localization of problems, sleep behaviour, medical consultation and sports/leisure activities. Onset, progression, duration of low back pain and some items on the influence of movement/positions presented less comparable data.
  
  
  CONCLUSIONS
  Even when two different methods of data acquisition are used, results suggest that the method used does not change the interpretation of results in the case of most items.
