ABSTRACT
Background: The Satisfaction and Recovery Index (SRI) is a generic importance-weighted health satisfaction tool to measure the process and state of recovery following musculoskeletal injuries. The objectives of this study are (1) to translate and cross-culturally adapt the SRI to Persian and (2) evaluate its psychometric properties. Methods: The forward-backward translation technique was used for translation, and two rounds of cognitive interviews were conducted to assess cultural appropriateness. Participants (n=100, mean age=32.5, 82%male) had acute (i.e., <30 days) musculoskeletal injuries of any etiology. Structural validity, construct validity, internal consistency, and test-retest reliability were evaluated. Results: Participants identified issues in 3/6 areas of a coding system during the cognitive interviews: comprehension/clarity, relevance, and inadequate response definition. These issues informed subsequent changes to arrive at the final version of the SRI-P. The SRI-P had adequate construct validity (P<0.001), the confirmatory factor analysis demonstrated a two-factor structure, the internal consistency was acceptable (Cronbach's α=0.83), and it was deemed reliable (ICC2, 1=0.72). Conclusion: The psychometric evaluation revealed that the SRI-P has adequate construct validity, internal consistency, and test-retest reliability. Unlike the original English version, the SRI-P has a two-factor structure, which appears to be related to cultural differences in interpreting some of the items. The clinical importance of this study is that the SRI (which captures the state of recovery and how important the various items of the tool are to each patient and how satisfied they are with their recovery) can now be available to surgeons and therapists in the orthopedic and rehabilitation realms in Persian populations.
ABSTRACT
BACKGROUND: The foundational basis for rehabilitation of musculoskeletal injury as a profession rests upon the ability of an organism to recover from a deviation in homeostasis, and the clinician's ability to influence that process. Much work has been done in an effort to describe and predict recovery from acute injury, in particular soft tissue injuries of the spine (whiplash and low back pain). Recent reviews have identified inconsistencies in the criteria for identifying recovery in this literature that hamper attempts at knowledge translation. PURPOSE: This article is intended to stimulate discussion around a new, standardised and acceptable set of criteria for discriminating between the injured individual who reaches a satisfying end to the experience of injury and the individual who does not reach that end. CONCLUSIONS: Self-discrepancy theory and self-determination theory are used to frame the discussion. It is hoped that the introduction of a new paradigm will lead to the development of more standardised, acceptable and useful outcomes, and will facilitate data synthesis from studies on prognosis and intervention for acute musculoskeletal injury.
