Cross-Cultural Adaptation and Psychometric Properties of The Thai Versions of The Patient-Reported Outcomes Measurement Information System Short Form – Anxiety 8a and the Pain Anxiety Symptoms Scale-20 in Individuals with Chronic Low Back Pain

Objective: To translate and cross-culturally adapt the Patient-Reported Outcomes Measurement Information System Short Form v1.0–Anxiety 8a and the Pain Anxiety Symptoms Scale-20 into Thai versions (T-PROMIS-Anx8a and T-PASS-20, respectively) and evaluate their psychometric properties in individuals with chronic low back pain (CLBP). Material and Methods: The translations and cultural adaptations were performed using the Functional Assessment of Chronic Illness Therapy (FACIT) guidelines. Thai individuals with CLBP completed the T-PROMIS-Anx8a and T-PASS-20. Psychometric evaluation including: internal consistency, test-retest reliability, and dimensionality. Construct validity was evaluated by computing correlations among the scores on the T-PROMIS-Anx8a, T-PASS-20, Thai version of the Hospital Anxiety and Depression Scale–Anxiety (T-HADS-A), and Thai version of the Fear Avoidance Beliefs Questionnaire (T-FABQ). Results: A total of 269 individuals with CLBP were included in the analyses. The T-PROMIS-Anx8a showed unidimensionality and the T-PASS-20 evidenced a 4-factor structure. Both measures demonstrated good to excellent internal consistency (Cronbach’s alphas ranged from 0.85 to 0.95), good test-retest reliability (ICC(2,1) ranged from 0.79 to 0.88), and neither ceiling nor floor effects were observed for any of the scales. Both measures evidenced acceptable convergent and discriminant validity, based on their associations with the T-HADS-A and T-FABQ. Conclusion: The T-PROMIS-Anx8a and T-PASS-20 were culturally adapted and evidenced acceptable psychometric properties for assessing anxiety in Thai individuals with CLBP

Responsiveness and clinically important differences of the PROMIS short form—depression 8a, anxiety 8a, and PASS-20 in individuals with chronic low back pain

Abstract. Introduction:. Depression and anxiety are the most commonly reported mental health conditions. The Patient-Reported Outcomes Measurement Information System Short Form v1.0—Depression 8a (PROMIS-D-8a), Anxiety 8a (PROMIS-Anx8a), and Pain Anxiety Symptoms Scale-20 (PASS-20) measures were designed to assess depression, general anxiety, and pain-related anxiety, respectively. Objectives:. To examine the responsiveness and estimate the clinically important differences (CIDs) of the Thai version of these measures in individuals with chronic low back pain (CLBP). Methods:. The study sample comprised 144 participants with CLBP. Responsiveness was evaluated by calculating the change scores, effect sizes (ESs), standardized response means (SRMs), area under the curve (AUC), and correlations between the change scores and associated Global Perceived Effect (GPE). We also estimated CIDs by the difference in mean change score between improved and unchanged groups and standard error of measurement (SEM) for each measure. Results:. Statistically significant differences in the mean change scores, ESs, and SRMs supported the responsiveness of all measures. The AUCs achieved acceptable discriminatory ability (0.71–0.72) for moderate improvement but not for any improvement (0.65–0.68). The correlations between GPE and change scores on all measures were low (r ranging 0.28–0.33). The estimated CIDs for the PROMIS-D-8a, PROMIS-Anx8a, and PASS-20 were 3.64, 4.20, and 8.80, respectively. Conclusion:. The PROMIS-D-8a, PROMIS-Anx8a, and PASS-20 measures were sensitive for detecting clinical changes over time in individuals with CLBP. The CID values can be used as reference points for assessing meaningful improvements in the domains assessed by these scales in clinical and research practice
