A psychometric examination of the Stronge-Brodt Nurses' Attitudes Toward Computers Questionnaire

The purpose of this study was to examine the factor structure and reliability of the Stronge-Brodt Nurses' Attitudes Toward Computers Questionnaire. The instrument was administered to nurses before (T1, n = 391) and after (T2, n = 265) the implementation of a computerized patient care information system. A factor analysis of each sample was carried out using the SPSS/PC+ factor procedure with varimax rotation and Kaiser normalization. The factor analyses for T1 and T2 were consistent and identified three factors that parallel those generated in a factor analysis performed by Schwirian et al (1989). In both samples of the current study, the internal consistency reliability for the first factor was high (T1 alpha = .91, T2 alpha = .92), whereas the second and third factors demonstrated diminished reliability. Overall instrument reliability was .93 at T1 and .92 at T2. This study, with relatively large sample sizes, provided further clarification of the factor structure and supported the high reliability of the instrument.
