Cross-cultural adaptation of the spa therapy checklist (SPAC) in Greek.

The importance of spa therapy is growing worldwide, with care practitioners paying more attention to how this intervention can alleviate various health issues. Multiple studies have been performed and reported on the efficiency of balneotherapy, creating a need to understand the quality of the information in the existing studies and how they can inform practitioners in promoting evidence-based practice. The SPAC assessment tool describes and assesses the quality of reports of interventional trials in balneotherapy. The present study had two goals. The first goal was the translation and cross-cultural adaptation of the SPAC assessment tool in Greek language following an internationally accepted methodology. The second goal was to assess the reliability of the tool employing test-retest and interrater reliability studies in a sample of 15 relative RCT papers and to assess the criterion validity of the Greek version by comparing its results with the original English version when assessing the same 15 papers. The results revealed that the SPAC checklist was translated and adapted in Greek without difficulties between the translators. Reliability of the SPAC was found excellent in both test-retest (ICC = .98) and interrater (ICC = .95) indexes. The criterion validity assessment for Greek version of SPAC checklist was also almost perfect (ICC = .98). In the present study, the Greek version of the SPAC checklist was found to be a comprehensible, reliable, and valid tool to assess the quality of interventional trial reports on the efficacy of spa therapy for cure and health enhancement.
