The patient enablement instrument for back pain turkish version, validity and reliability study.

Abstract

BackgroundThe only survey that assesses the ability of individuals with low back pain to self-manage their condition is the Patient Enablement Instrument for Back Pain (PEI-BP).ObjectiveThe study aims to create a Turkish version of PEI-BP and test its validity and reliability.Methods67 individuals (47 females, 20 males) with low back pain participated, comprising. Reliability was evaluated through test-retest reliability, internal consistency, and repeatability measures. Validity was assessed via structural, content, face validity analyses. Floor and ceiling effects were examined to ensure a comprehensive evaluation. Additionally, the relationship between PEI-BP and pain intensity, Brief Illness Perception Questionnaire (BIPQ), Fear Avoidance Beliefs Questionnaire (FABQ), Oswestry Disability Index (ODI), and Short Form-36 (SF-36) was explored.ResultsThe Intraclass Correlation Coefficient value (0.795) and Cronbach's α (0.886) of PEI-BP were high. The goodness-of-fit values for the model, including fit indices and reference ranges, indicated strong validity. The PEI-BP demonstrated the absence of both floor and ceiling effects. Correlations between PEI-BP and pain intensity, BIPQ, FABQ, ODI, and SF-36 exhibited a range from weak to good (0.258 to -0.440).ConclusionsPEI-BP has demonstrated high reliability and good validity. PEI-BP can be used to evaluate Turkish-speaking individuals with low back pain.ClinicalTrials.gov ID: NCT06109246 (Date: 10/25/2023).
