“Since You’re Asking. . . ”: Free Text Commentaries in an Epidemiological Study of Low Back Pain Consulters in Primary Care

As part of a longitudinal mixed-method study on low back pain (LBP), free-text comments were invited at the end of the 12 month follow-up survey questionnaire. 80% of respondents used this option and provided a wealth of material so that comparisons could be made with survey and interview results. People reported pain in other parts of the body apart from LBP, and illustrated the impact of LBP on physical ability and work, psychological well-being and social activities. Free-text material offers valuable insights that strengthen the findings of the survey, and the study as a whole.
