About this study

The secondary objectives are:

A. To search for correlations between the acceptance score (AAQ-II Questionnaire) and scores for coping (CSQ), avoidance (FABQ), understanding (BBQ), anxiety and depression (HADS) and quality of life (SF-12) at baseline.

B. To describe the kinetics of changes in various parameters (acceptance, coping, avoidance, understanding, anxiety and depression, quality of life, ODI) over 6 months.

C. To evaluate the agreement between two methods of questionnaire presentation: Paper collection versus collection by Tablet PC.

Treatment and study plan

Primary outcomes

  1. Classification of the patient as a responder or a non responder

    Time frame: 6 months

    The response to treatment will be evaluated by the ODI (Oswestry Disability Index) at 6 months: a patient will be considered as a responder when the absolute change between the score at 6 months and inclusion is at least 10 points (Ostelo RW et al., 2008).

    This outcome is a qualitative variable with two options: responder or non-responder. The fact that we define in an apriori fashion who is a responder or not does not mean that we have created multiple outcomes. This is a single outcome.
