The original instrument Beliefs and Attitudes toward Visitation in ICU Questionnaire (BAVIQ): Beliefs and Attitudes towards Visitation in ICU Questionnaire (BAVIQ) were translated into Portuguese language using forward and backward translation measures. The translated version of the tool was validated for its use in Portugal using Content Validity Index (CVI) by Lynn's (1986). The panel of three experts was purposively instituted to assess the validity of the tool. The valid instrument was administered to non-random probability sample of 100 intensive care nurses (n=100) from two regional tertiary care hospitals in Portugal. The descriptive statistical measures were applied to explore beliefs and attitude of nurses towards liberalization of visitation. One sample t test was used to assess level of significance of the responses. Pearson Correlation was applied to find relationship between age, years of experience and level of education with beliefs and attitudes of nurses.
