Abstract Background Self-rated health status has been shown to be related to physical function. Therefore changes in functional ability should be associated with changes in general health. However functional needs may vary greatly between individuals. The purpose of this study was to propose and test a model of association between patient identified functional problems and responses to global measures of health in low back pain patients. Methods Participants in a low back pain clinical trial were followed up for 12 months. A series of analyses were undertaken using the Jonckheere-Terpstra test and chi-square for trends to determine the associations between two individualised items related to function and measures of overall improvement in condition general health status and performance of usual activities . Results Significant associations between responses to the five items were found. Performance of usual activities is significantly associated with ratings .
