The correlational descriptive study was conducted to describe computer knowledge, attitudes and skills of nurses at Peoples Hospital of Beijing Medical University (BMU), to compare the computer knowledge, attitudes and skills of nurses receiving formal and those receiving informal computer training, and to examine the relationships among the three variables. A proportionate stratified random sampling was used to select 169 nurses working in Peoples Hospital of BMU. Demographic Data Recording Form was used to collect samples demographic characteristics. Computer knowledge, computer attitudes and computer skills were measured using the Nurses Computer Knowledge Questionnaire (NCKQ), the Nurses Computer Attitudes Scale (NCAS) and the Nurses Computer Skills Scale (NCSS) developed by the researcher. The content validity of the questionnaire was examined from which the content validity index (CVI) of NCKQ, NCAS and NCSS was .98, .93 and .95, respectively. The reliability of NCKQ was tested from which the test-retest reliability coefficient was .90. The reliability of the other two instruments was tested from which Cronbachs alpha coefficients obtained for NCAS and NCSS obtained were .72 and .83, respectively. Data were analyzed in terms of percentage, means, standard deviation, and partial correlation coefficient. The findings of this study found that the overall computer knowledge and skill levels of nurses were at moderate levels and the computer attitudes were neutral. No significant difference of computer knowledge, attitudes and skills were found when compared between nurses receiving formal and those receiving informal computer training. Nurses computer skills were slightly positively correlated to both computer knowledge and computer attitudes. However, no significant correlation between computer knowledge and computer attitudes was found. Implications for nursing administration, practice, education and research were described. Nursing intervention program to enhance nurses computer knowledge, skills, as well as attitudes is recommended.
