Description:

Composite scale of the self-questionnaire type specific to lumbago, much used since the 90s because of its speed (5 minutes). The objective is to measure the pain and functional repercussions of lumbago on the simple actions of daily life by bringing in a cognitive-behavioural dimension for chronic pain (physical, psychological and social).

The patient must reply to 4 groups of separate questions concerning 1) daily activities (7 questions); 2) professional activities and leisure activity (3 questions); 3) anxiety/depression (3 questions); and 4) sociability (3 questions). A total of 16 questions, using an analogue visual scale for each question.

The patient must evaluate the level of pain associated with the question and mark the straight line of the EVA on the sheet by an X.

General comment on reliability:

The construct validity has shown significant correlation with the other physical and psychological criteria as well as a significant discriminatory validity between acute lumbago and non-acute. The predictive validity of the scores enables targeting new cases of lumbago: if the dimensions "daily activity" and "work-leisure" are >50%, and the "anxiety-depression" dimensions and “social behaviour” are <50%, a medical treatment will be suggested. If the dimensions are the inverse, it seems appropriate to favour a behavioural treatment. If all the dimensions are >50%, a mixed treatment will be proposed.
