Introduction: This study aimed to describe the steps to construct and validate a questionnaire to identify the knowledge, skills and attitudes of hospital pharmacists in the use of information technology and electronic tools to support clinical practice. Materials and Methods: The electronic questionnaire with 26 items, 8 dimensions and 74 variables was constructed based on a bibliographical review and validated by a experts panel (n=10), who evaluated in two cycles the relevance and clarity of each question by using scale (relevance: 1-irrelevant, 2-somewhat relevant, 3-relevant and 4-very relevant and Clarity: 1-not clear, 2-somewhat clear, 3-clear and 4-very clear). The Content Validity Index and the degree of agreement were calculated. The questionnaire was tested with hospital pharmacists, adjusted and used in definitive data collection in Brazil. Results: The 1st cycle Content Validity Index-CVI was 0.9635±0.0566 and 1 at the 2nd cycle. The questions with CVI<0.8 were adjusted. The degree of agreement was 82.5%(1st cycle) and 99.61%(2nd cycle). The validated questionnaire was submitted to the receptivity test with a rate of 4.67 responses per day. After the changes suggested the questionnaire was applied to Brazilian hospital pharmacists (n=1373) obtaining a response rate of 25.3% (n=348). Conclusion: The validated questionnaire presents acceptable content validity psychometric measures and may lead to know the hospitals pharmacists gaps in knowledge, skills and attitudes in the use of information technology and electronic tools.
