The intervention group received two 45-minute lectures at the workplace with an interval of 2 weeks. The lectures were coherent allthough different. They consisted of information on the scientific knowledge on the etiology of LBP, basic anatomy, common myths about LBP, a theory of non-specific LBP being caused by muscular functional disturbances (Indahl 1999), pain physiology, and scientific knowledge on seemingly appropriate coping strategies to prevent a prolonged course. Emphasis was made to reduce pain-related fear of movement and catastrophizing thoughts and beliefs. Instead, activity during pain episodes was promoted as well as a natural use of the back despite pain. A non-directive approach was used (non-imperativ wording and absence of giving advice). The purpose was to provide information but let the participant make their own conclusions on how and if to use the information in present/future coping with pain.
