Reliability and Validity of Adapted Russian Version of Hospital for Special Surgery Lumbar Spine Surgery Expectations Survey

Abstract

Background: Patients’ expectations are an important determinant in their decision to undergo lumbar spinal surgery—particularly their expectations of recovery after surgery. The Hospital for Special Surgery Lumbar Spine Surgery Expectations Survey (HSS-LSSES) is one tool used to assess this; however, the original version was only available in English. Objective: We sought to evaluate the reliability and validity of a translated and adapted Russian-language version of the HSS-LSSES. Methods: This was a prospective study of 91 patients with degenerative disc disease who underwent lumbar spine surgery with instrumented fixation at a single institution in Saint Petersburg, Russia. Patients were recruited between December 2019 and February 2021 and asked about their expectations of surgery with a translated and adapted Russian version of the HSS-LSSES. To analyze construct validity, participants also completed disease-specific and general quality-of-life scales (Oswestry Disability Index, European Quality of Life–5 Dimensions, and 36-item Short-Form Health Survey). Intraclass correlation coefficients (ICCs; 2-way random effects model, absolute agreement) were used to determine test-retest reliability of the total score of the Russian HSS-LSSES. Internal consistency was evaluated through the estimation of Cronbach’s alpha between the test and retest response of the questionnaire. Results: The test-retest stability of the Russian HSS-LSSES evaluated through the estimation of ICC was found to have good stability. The instrument was shown to have high internal consistency. Conclusion: This study demonstrates that a translated and adapted Russian version of HSS-LSSES had good internal consistency, reliability, construct validity, and no floor and ceiling effects. Therefore, we recommend its use as a tool for evaluating Russian-speaking patients’ expectations before lumbar spine surgery.

Emerging Need for PROMs to Measure the Impact of Spine Disorders on Overall Health and Well-being: Measuring Expectations as an Example for Lumbar Degenerative Spondylolisthesis

“…The Expectations Survey was developed based on the perspectives of patients with diverse diagnoses including LDS and, therefore, can potentially address various consequences of LDS on physical and mental well-being [27]. The Expectations Survey has been translated into other languages and used by other researchers [2,10,15,25,29,35]. It addresses anticipated outcomes, and although not a gold standard for current conditions, it is an example of a single survey that can simultaneously address multiple issues that are important to patients and that impact their overall health.…”
