Clinical Trial
HKF-R 10 - screening for predicting chronicity in acute low back pain (LBP): a prospective clinical trial.
Prospective cohort study. ⋯ Using the items listed above, the study was able to predict a patient's risk of developing chronic LBP with a probability of 78%. These items were assembled in a brief questionnaire and were paired with a corresponding evaluative tool. This enables practitioners to assess an individual patient's risk for chronicity by means of a simple calculator in just a few minutes. A validation study for the questionnaire is currently being prepared. MINI ABSTRACT: The objective of this study was the development of a brief questionnaire to assess the risk for chronicity for LBP.

Studies with (sub) acute back pain patients show that negative expectancies predict pain and disability at a one-year follow up. Yet, it is not clear how expectations relate to other factors in the development of chronic disability such as pain and fear. This study investigates the relationship between expectations, pain-related fear and pain and studies how these variables are related to the development of chronic pain and disability. ⋯ In conclusion, expectancy, negative affect and fear avoidance beliefs are interrelated constructs that have predictive value for future pain and disability. Clinically, it can be helpful to inquire about beliefs, expectancy and distress as an indication of risk as well as to guide intervention. However, the strong interrelations between the variables call for precaution in treating them as if they were separate entities existing in reality.

This study examined the role of work-related, psychosocial and psychological factors in predicting functional and social disability in working employees. In a cross-sectional design, 890 working employees (reporting at least 1 day of back pain during the past year) completed self-report measures of back pain, disability, pain-related fear, negative and positive affectivity, job satisfaction, job stress and physical work load. Regression analyses revealed that pain intensity was a strong predictor of functional (beta = .69, p < .001) and social disability (beta = .67, p < .001). ⋯ Further, (singular) mediation tests indicated that fear for (re)injury partially mediated the relation between pain intensity and disability, and between negative affectivity and disability. Finally, path analyses revealed both fear and pain intensity as mediators between negative affectivity and disability. Overall, our findings point at the relevance of the cognitive-behavioral model of avoidance in occupational settings.
