- Objective: Patient enablement reflects patient's understanding of and coping with illness. The aim of this study was to investigate the content validity, construct validity, internal consistency and selfrated change (SRC) of the Patient Enablement Instrument (PEI) in patients with whiplash-associated disorders, cervical radiculopathy and mixed chronic pain treated in different settings.Design: Psychometric analyses. Participants: Patients with disabling non-malignant chronic musculoskeletal pain.Methods: Participants answered questionnaires on disability (Neck Disability Index (NDI) or Functional Rating Index (FRI)), anxiety/depression (Hospital Anxiety and Depression Scale; HADS) and general health (EuroQol; EQ-5D). Content validity, construct validity (confirmatory factor analysis), internal consistency and cut-off for SRC were investigated for the PEI after treatment. The SRC value was the receiver operating characteristic (ROC) curve optimal cut-off point.Results: After treatment all items were completed by 516 patients (mean standard deviation (SD) age 45.1 years (SD 10.1), women 75% (n=385)). The 1-factor PEI model had approximate fit to the data. The internal consistency Cronbach's alpha was between 0.878 and 0.929 for the 3 groups. Correlations between the PEI and the NDI/FRI, HADS and EQ-5D were fair to good. The SRCROC for whiplash-associated disorders, cervical radiculopathy and mixed chronic pain groups was 5, 6 and 4 points in the PEI, respectively.Conclusion: The PEI showed fair content validity, construct validity and internal consistency. However, the scale needs further development to improve measurement of change.

- ObjectiveThe purposes of this study were to examine whether any differences in function and health exist between patients with cervical radiculopathy (CR) due to disk disease scheduled for surgery and patients with chronic whiplash-associated disorders (WADs) and to compare measures of patients' physical function with those obtained from healthy volunteers.MethodsThis is a cross-sectional study of patients with CR (n = 198) and patients with chronic WAD (n = 215). Patient data were compared with raw data previously obtained from healthy people. Physical measures included cervical active range of motion, neck muscle endurance, and hand grip strength. Self-rated measures included pain intensity (visual analog scale), neck disability (Neck Disability Index), self-efficacy (Self-Efficacy Scale), and health-related quality of life (EuroQol 5-dimensional self-classifier).ResultsPatient groups exhibited significantly lower performance than the healthy group in all physical measures (P < .0005) except for neck muscle endurance in flexion for women (P > .09). There was a general trend toward worse results in the CR group than the WAD group, with significant differences in neck active range of motion, left hand strength for women, pain intensity, Neck Disability Index, EuroQol 5-dimensional self-classifier, and Self-Efficacy Scale (P < .0001).ConclusionsPatients had worse values than healthy individuals in almost all physical measures. There was a trend toward worse results for CR than WAD patients.
