Adaptation and validation of an abbreviated version of the SIPAT integrated psychosocial risk scale in patients with liver cirrhosis candidates for liver transplantation (SIPAT-11).

Abstract

Introduction: Patients with liver cirrhosis who are candidates for liver transplantation must be evaluated both clinically and socially in order to obtain the optimal outcomes and avoid futile therapeutic measures. For the evaluation of the social aspects in these patients, no validated scale in Spanish is available. The SIPAT (Stanford Integrated Psychosocial Assessment for Transplantation) scale is an instrument that measures the social, family and psychological aspects in candidates for solid organ transplantation. The objective of this study is to adapt and validate an abbreviated version of the SIPAT scale in Spanish for patients with liver cirrhosis.

Material and methods: Prospective observational study carried out in the Hepatology Unit of the La Fe Unversity Hospital in Valencia, by questionnaire validation methodology. To analyze the reliability of the questionnaire, the internal consistency of all variables was calculated, for variability an exploratory factor analysis, and for stability the test-retest test was carried out.

Results: 96 patients who were admitted for decompensated cirrhosis to the Hepatology Unit of the La Fe Hospital in Valencia between November 1, 2017 and January 31, 2017 were selected. 84% were men, the mean age was 60.01 (SD 10.12) years. In 73.2% of those admitted, the etiology of cirrhosis was alcoholic. 14.4% had a Child's stage A, 57.7% B and 27.8% C. The internal consistency of all variables reached a Cronbach's Alpha of 0.766. In the exploratory factor analysis, 6 dimensions of the questionnaire were identified that explain 84.27% of the total variability. To see the stability of the instrument, the measurement was repeated at 2 and 6 months of follow-up, obtaining in the test-retest a kappa agreement of 0.612 and 0.565 respectively.

Conclusion: The SIPAT-11 questionnaire has good psychometric characteristics in cirrhotic patients who are candidates for liver transplantation. It is easy to complete and can be administered by professionals who are not specialists in the area of Mental Health.
