Patterns of Approach to Activity in 851 Patients With Severe Chronic Pain

Objectives: The Avoidance-Endurance Fast-Screen (AEFS) is a 9-item self-report questionnaire that classifies patients with back pain into 4 activity-related subgroups, based on the Model of pain. objective this study was to translate AEFS Danish and investigate its discriminative abilities in large, diverse patient sample. Materials Methods: A total 851 specialist care-seeking severe chronic conditions participated cross-sectional study. Participants were categorized as showing “distress-endurance” (DER), “eustress-endurance” (EER), “fear-avoidance” (FAR), or “adaptive” (AR) pattern. Principal component analysis reduced large number psychological variables beforehand. Construct outcome-based validity explored using multivariate variance. Results: Of participants, 33.6% DER, 29.4% EER, 22% FAR, 15% adaptive. showed factors behavior, affective distress, dysfunctional thoughts. AEFS-DK discriminated all subgroups terms their behavior EER>DER>AR>FAR. FAR less moderate/vigorous activity than DER EER more sedentary time EER. higher thoughts, poorer outcomes AR Conclusion: results indicate good construct discriminating avoidance-endurance model-related respect approach variables, reported physical activity. Concerning validity, 2 DER/FAR AR/EER could be distinguished inconclusive for eustress-endurance subgroup. Future studies are warranted longitudinal research designs investigating whether differ treatment effects long-term prognosis.
