The model of fear of movement/(re)injury runs clockwise from catastrophizing: evidence from a sample of outpatients with chronic non-specific low back pain.

Objective: To provide evidence that catastrophizing is the primer of the cognitive-behavioural model of fear of movement/(re)injury (FAM).

Design: A cross-sectional analysis of 180 outpatients with chronic non-specific low back pain who completed the Pain Catastrophizing Scale (PCS), the Tampa Scale of Kinesiophobia (TSK), the Roland-Morris Disability Questionnaire (RMDQ), the Hospital Anxiety and Depression Scale - Depression (HADS-D), and a pain intensity numerical rating scale (NRS). The intercorrelations of the outcome measures were estimated using Pearson's correlation coefficient (r), and regression analyses were used to examine their predictive values by following the left side of the FAM clockwise from the PCS (p = 0.
