Cross-cultural translation, adaptation, and validation of the Amharic version pain self-efficacy questionnaire in people with low back pain in Ethiopia

Self-Efficacy in Nepali Adults With Musculoskeletal Pain: Measurement Properties of Hard-Copy and Online Versions of the Pain Self-Efficacy Questionnaire

The Pain Self-Efficacy Questionnaire (PSEQ) is commonly used in pain self-efficacy research. Yet its Nepali translation is unavailable, limiting the ability to conduct cross-cultural research on the role of self-efficacy in musculoskeletal pain and its management. This study aimed to 1) translate and culturally adapt the 10-item (PSEQ-10) and 2-item (PSEQ-2) versions of the PSEQ into Nepali, 2) evaluate their measurement properties in Nepali adults with musculoskeletal pain, and 3) evaluate whether the type of administration (ie, hard-copy vs online) affected their measurement properties. The measurement properties of different administrations of the Nepali PSEQ-10 and PSEQ-2 were evaluated in 180 Nepali adults (120 hard-copy and 60 online administrations) with musculoskeletal pain. We conducted confirmatory factor analyses and estimated the measures' internal consistencies, test-retest reliabilities, and smallest detectable changes using standard error of measurement. We planned to conclude that the measures were valid if ≥ 75% of the validity hypotheses were supported. The results supported unidimensionality for the Nepali PSEQ-10. The Nepali PSEQ-2 and PSEQ-10 evidenced excellent internal consistencies (Cronbach alphas = .90-.95) and good to excellent test-retest reliabilities (intraclass correlation coefficient = .61-.85) for both administrations. Construct validity (r's ≥ .20) and concurrent validity (r's ≥ .83) were supported, as hypothesized. Both hard-copy and online administrations of the Nepali PSEQ-2 and PSEQ-10 are similar, reliable, and valid ways to assess self-efficacy in Nepali adults with musculoskeletal pain. The findings should facilitate telehealth and cross-cultural research on pain self-efficacy in Nepal. PERSPECTIVE: This is the first Nepali adaptation of a self-efficacy scale with testing of measurement properties for hard-copy and online administrations. It will facilitate the assessment of pain self-efficacy in clinical practice and research and facilitate a deeper cross-cultural understanding of the role of self-efficacy in musculoskeletal pain.

Psychometric properties of the translated Spanish version of the Pain Self-Efficacy Questionnaire

Introduction

Some patients with rotator cuff injuries do not report significant changes in pain-related outcomes. Pain self-efficacy, which is commonly assessed using the Pain Self-Efficacy Questionnaire, may contribute toward this outcome. However, a Spanish adaptation of this questionnaire is currently lacking. Therefore, this study's purpose was developing the Spanish version of this questionnaire, and assess its psychometric properties.

Methods

The Spanish version of the Pain Self-Efficacy Questionnaire was translated and culturally adapted, and a sample of 107 patients with rotator cuff injuries completed the questionnaire to examine its convergent validity (analyzing its correlation with the Tampa Scale of Kinesiophobia), its test-retest reliability, for which a subset of 40 participants completed again the questionnaire, and its internal consistency.

Results

Translation was conducted without any problems, and 107 participants completed the study. Mean scores for the Pain Self-Efficacy Questionnaire were 45.2 points (standard deviation, 11.4). The Pain Self-Efficacy Questionnaire showed a moderate negative correlation with the Tampa Scale of Kinesiophobia (Pearson's correlation index r = -0.48) supporting its convergent validity. High test-retest reliability (Intraclass Correlation Coefficient of 0.90) and excellent internal consistency (Cronbach's α value of 0.92) were also found.

Discussion

The Spanish version of the Pain Self-Efficacy Questionnaire presents high validity, test-retest reliability, and internal consistency to assess pain self-efficacy in patients suffering rotator cuff injuries in Spanish-speaking settings.

Measurement properties of the Pain Self-Efficacy Questionnaire in populations with musculoskeletal disorders: a systematic review

A higher level of pain self-efficacy has been suggested as a predictor of a better outcome in patients with musculoskeletal disorders. The Pain Self-Efficacy Questionnaire (PSEQ) is one of the most frequently used patient-reported outcome measures for pain self-efficacy. The purpose of this study was to conduct a systematic review that would identify, appraise, and synthetize the psychometric properties of the PSEQ. Embase, MEDLINE, and CINAHL databases were searched for publications reporting on psychometric properties of the PSEQ in populations with musculoskeletal disorders. After applying selection criteria on identified citations, 28 studies (9853 participants) were included. The methodological quality as measured with the COSMIN risk of bias tool varied from adequate to very good for most measurement properties. The results showed a weighted mean intraclass correlation coefficient of 0.86 (range: 0.75-0.93) for test-retest reliability for the original 10-item PSEQ and the minimal detectable change at 95% confidence interval was 11.52 out of 60 points. Effect size and standardized response mean values were 0.53 and 0.63, respectively, whereas the minimal clinically important difference ranged from 5.5 to 8.5 in patients with chronic low back pain. Internal consistency (Cronbach alpha) ranged from 0.79 to 0.95. The results also showed that the PSEQ has low to moderate correlations with measures of quality of life, disability, pain, pain interference, anxiety, depression, and catastrophizing. Finally, the PSEQ has been adapted and validated in 14 languages. Overall, the results demonstrate that the PSEQ has excellent validity, reliability, and responsiveness. Further high-quality studies are needed to determine responsiveness in populations other than chronic low back pain.
