[Chronic low back pain : Replication of different reaction groups].

Background: The aim of the study was to replicate the different reaction groups: "Fröhlicher Durchhalter (FD)" who are characterised by a positive mood and endurance strategies, "Depressiver Durchhalter (DD)" with depressive mood and cognitions to hold on and "Depressiver Vermeider (DV)" who are depressed with social and physical avoidance strategies. The replication was conducted with more feasible methods than the Kiel Pain Inventory (KPI), which had been frequently used in former research. This might effectuate a superior intervention outcome.
