Psychological changes and the resolution of acute neck pain after a motor vehicle accident

In general the relationships between the measures of self-discrepancy and enmeshment and mood were in accord with both theoretical predictions and previous observations. Resolution of pain was associated with a reduction in enmeshment but not to change in self-discrepancy. Multilevel analyses of the diary data showed that concordance between actual and ideal performance increased over the 21 days of data collection. These data provide preliminary support for aspects of self-discrepancy theory and the self-pain enmeshment model.
