Assessing pain and pain-related fear in acute low back pain: what is the smallest detectable change?

The Tampa Scale for Kinesiophobia (TSK) and the Fear-Avoidance Beliefs Questionnaire (FABQ) are frequently used questionnaires for pain-related fear, and the visual analogue scale (VAS) is for pain. This study aims to determine the smallest detectable change (SDC) of these questionnaires in patients with acute low back pain (LBP), as well as ceiling and/or floor effects. The SDC for the TSK (scoring range: 17-68) was 9.2 (95% CI: 8.4; 10.3). The estimated SDC was 9.4 (95% CI: 8.5; 10.6) and 12.7 (95% CI: 11.5; 14.1) for the FABQ physical activity subscale (scoring range: 0-24) and/or work subscale (scoring range: 0-42), respectively. For the VAS for pain (0-100 mm), the SDC turned out to be 36.2 mm (95% CI: 32.4; 41.0). The FABQ physical activity subscale and pain (VAS) seem to have considerable problems in detecting improvement and deterioration. The TSK appears to be able to detect improvement as well as deterioration. The SDCs of the (subscales of) questionnaires range from 18% to 40%. Floor and/or ceiling effects were detected for most scales, except the TSK total and the TSK activity avoidance subscale. These results should be considered when using these questionnaires as measures of therapeutic change in acute LBP.

<h3><b>Background</b></h3> Psychologically informed practice emphasizes routine identification of modifiable psychological risk factors being highlighted. <h3><b>Objective</b></h3> The purpose of this study was to test the predictive validity of the STarT Back Screening Tool (SBT) in comparison with single-construct psychological measures for 6-month clinical outcomes. <h3><b>Design</b></h3> This was an observational, prospective cohort study. <h3><b>Methods</b></h3> Patients (n=146) receiving physical therapy for low back pain were administered the SBT and a battery of psychological measures (Fear-Avoidance Beliefs Questionnaire physical activity scale and work scale [FABQ-PA and FABQ-W, respectively], Pain Catastrophizing Scale [PCS], 11-item version of the Tampa Scale of Kinesiophobia [TSK-11], and 9-item Patient Health Questionnaire [PHQ-9]) at initial evaluation and 4 weeks later. Treatment was at the physical therapist9s discretion. Clinical outcomes consisted of pain intensity and self-reported disability. Prediction of 6-month clinical outcomes was assessed for intake SBT and psychological measure scores using multiple regression models while controlling for other prognostic variables. In addition, the predictive capabilities of intake to 4-week changes in SBT and psychological measure scores for 6-month clinical outcomes were assessed. <h3><b>Results</b></h3> Intake pain intensity scores (β=.39 to .45) and disability scores (β=.47 to .60) were the strongest predictors in all final regression models, explaining 22% and 24% and 43% and 48% of the variance for the respective clinical outcome at 6 months. Neither SBT nor psychological measure scores improved prediction of 6-month pain intensity. The SBT overall scores (β=.22) and SBT psychosocial scores (β=.25) added to the prediction of disability at 6 months. Four-week changes in TSK-11 scores (β=−.18) were predictive of pain intensity at 6 months. Four-week changes in FABQ-PA scores (β=−.21), TSK-11 scores (β=−.20) and SBT overall scores (β=−.18) were predictive of disability at 6 months. <h3><b>Limitations</b></h3> Physical therapy treatment was not standardized or accounted for in the analysis. <h3><b>Conclusions</b></h3> Prediction of clinical outcomes by psychology-based measures was dependent upon the clinical outcome domain of interest. Similar to studies from the primary care setting, initial screening with the SBT provided additional prognostic information for 6-month disability and changes in SBT overall scores may provide important clinical decision-making information for treatment monitoring.
