The purpose of this study was to examine the dimensions of coping, measured by the subscales of the new revised Coping Strategies Questionnaire (CSQ-R) using factor analysis, and to perform cluster analysis on these factors to explore the existence of distinct subgroups. No published studies have identifed subgroups of chronic pain patients based on the use of CSQ coping strategies. ⋯ This paper is the first to report empirically derived subgroups from scores on the CSQ or CSQ-R. In addition, the three clusters were significantly different across measures of pain, psychological distress, and levels of physical functioning, demonstrating validity for the clusters.

Comparative Study
Cross-cultural adaptation of the Roland-Morris questionnaire for German-speaking patients with low back pain.
Cross-cultural adaptation and cross-sectional psychometric testing. ⋯ Because the German version of the Roland-Morris Questionnaire seems to be reliable and valid for the assessment of the functional status in German-speaking patients with low back pain, the use of this translated instrument can be recommended in future clinical trials.

A need to consider possible gender differences in pain research has been recognized by researchers during the last decades. As part of a psychometric evaluation of the Swedish version of the Multidimensional Pain Inventory (MPI-S), we performed gender-differentiated analyses of the internal consistency, validity and sensitivity to change of the MPI-S in a sample of 235 individuals (129 females, 106 males) suffering from long-term non-specific pain from the lower back and/or neck region. The construct validation and sensitivity analyses were performed by using validated self-report measures and direct observational assessment techniques as external constructs. ⋯ Altogether, the results showed a similar pattern across gender, although some divergences were detected, such as the substantially weaker negative correlation between perceived supportive behaviour from significant others and punishing responses for males compared to females. In conclusion, we recommend the use of sections 1 and 2 of the MPI-S as a psychometrically evaluated and comprehensive instrument in the assessment of individuals suffering from chronic non-specific low back pain or neck pain.

Clinical TrialLumbar spine range of motion as a measure of physical and functional impairment: an investigation of validity.
To investigate the validity of the spinal range of motion models outlined in the second and fourth editions of the American Medical Association Guides to the evaluation of permanent impairment (AMA Guides), for assessing the percentage impairment in chronic low back pain patients. ⋯ There was no evidence for a relationship between low back range of motion and impairment, and thus it would appear illogical to evaluate impairment in chronic low back pain patients using a spinal range of motion model when aiming to measure or compensate disability.
