ABSTRACT
OBJECTIVES: To assess the reliability and validity of the Greek version of Nursing Activities Score (NAS), and Therapeutic Intervention Scoring System for Critically Ill Children (TISS-C) in a Greek Paediatric Intensive Care Unit (PICU). RESEARCH METHODOLOGY: A methodological study was performed in one PICU of the largest Paediatric Hospital in Athens-Greece. The culturally adapted and validated Greek NAS version, enriched according to the Norwegian paediatric one (P-NAS), was used. TISS-C and Norwegian paediatric interventions were translated to Greek language and backwards. Therapeutic Intervention Scoring System (TISS-28) was used as a gold standard. Two independent observers simultaneously recorded 30 daily P-NAS and TISS-C records. Totally, 188 daily P-NAS, TISS-C and TISS-28 reports in a sample of 29 patients have been obtained during five weeks. Descriptive statistics, reliability and validity measures were applied using SPSS (ver 22.0) (pâ¯≤â¯0.05). RESULTS: Kappa was 0.963 for P-NAS and 0.9895 for TISS-C (pâ¯<â¯0.001) and Intraclass Correlation Coefficient for all scale items of TISS-C was 1.00 (pâ¯<â¯0.001). P-NAS, TISS-28 and TISS-C measurements were significantly correlated (0.680â¯≤â¯rhoâ¯≤â¯0.743, pâ¯<â¯0.001). The mean score(±SD) for TISS-28, P-NAS and TISS-C was 23.05(±5.72), 58.14(±13.98) and 20.21(±9.66) respectively. CONCLUSION: These results support the validity of P-NAS and TISS-C scales to be used in greek PICUs.
