Translation and validation of family satisfaction questionnaire of adult patients hospitalized in Intensive Care Units

a standard tool is required to investigate and determine of family satisfaction level of adult patients hospitalized in Intensive Care Units (ICUs). Since such tools haven''t been localized in Iran so far، the aim of this study was translation and validation of family satisfaction questionnaire (FS ICU-34) of adult patients hospitalized in ICUs in Iran. This is a methodological study. Face and content validity process was carried out after translating English version of the tools through forward-backward translation technique، confirmed by WHO (World Health Organization)، and exploratory factor analysis was conducted by investigating three hundred questionnaires completed by family members of adult patients hospitalized in ICUs of Tehran hospitals in order to investigate construct validity. in exploratory factor analysis، three subscales including: satisfaction with medical staff performance (12 items)، comfort (12 items) and decisionmaking (6 items) were determined by Eigen value above one and factor load above 0. 5. Cronbach''s alpha in the first، the second and the third subscale were respectively achieved; 0. 93، 0. 92 and 0. 84 and Cronbach''s alpha of the tools was achieved 0. 95. In this study the number of the questions was decreased to thirty. after performing procedures of determining validity، necessary changes in the number of the questions، writing and number of the questionnaire areas were carried out and it became clear that the Persian version of the questionnaire FS-ICU 34 benefits high reliability (α= 0. 95). Removingsome questions due to their low scores allocated by Experts’panel was done during the stages of determining validity and it was done among Iranian respondents due to cultural incompatibility. Content validity index of all the satisfaction Persian tools of family members of adult patients hospitalized in ICUs through two S-CVI/Ave and S-CVI/Universal validity methods were respectively achieved 0. 97 and 0. 86، which is indicating good validity of the Persian version of the tools. Also by shortening Persian version of the above tools، answering themwould be easier.
