Cross-Cultural Translation and Validation of Selected Tools to Evaluate Patients Satisfaction Level in Different Pain Management Settings

Abstract

Background: Pain is the most common reason to seek medical care. Various medical issues can be evaluated by using different validated assessment instruments. The health care providers face methodological issues and problems associated with validated instruments at different clinical settings. to overcome this situation translation is the most common procedure. This study was designed to evaluate the applicability of common clinical evaluation tool after linguistic validation to assess the relation between pain reduction and level of satisfaction in patients with the outcome of pain management. Different tool such as VAS, MISS-21, APS-PQR and PSRS were translated and validated for using in emergency facility, post-operative ward and in chronic low back pain patient at outpatient setting.
Methods: The translation process included synthesis translation, forwardstranslation, backwards translation, reconciliation and pretesting steps. The success of the translation process was evaluated by scoring each item into comparability, similarity of interpretability and understandability, which ranged by Likert scales. The properties of the provincial language versions of the three questionnaires for pain management were relevant and comprehensive. The MISS-21 subscale was used to measure the satisfaction level of the patients with the consultation into four categories, and the results are expressed as the mean±SD. The unpaired t-test was performed. The APS-POQ-R consisted of 23 primary items in which the response was measured as a continuous scale.
Results: The mean value of patient satisfaction with the pain treatment was 7.42(±1.34). The item correlation and reliability (Cronbach’s alpha) for all 20 items was 0.85. The PSSS was used to evaluate the satisfaction level in chronic low back pain. The comparison of the pain severity was expressed as the mean±SD, and a paired test was performed, which was significant.
Conclusion: These tools were suitable to assess the relationship between painreduction and level of satisfaction in patients. Adaptation of the translated and validated tools may be beneficial for the research community.
