Testing an instrument measuring Greek nurses' knowledge and attitudes regarding pain

This pretest-post-test study was conducted to test the construct validity, test-retest reliability, and internal consistency of the Nurses' Knowledge and Attitudes Survey Regarding Pain with Greek nurses. Forty-six registered nurses were randomly assigned to an expert or nonexpert group. The expert group viewed 4 translated educational videotapes about pain management. The nonexpert group received no pain education. All of the nurses completed a pretest and a post-test using a Greek translation of the Nurses' Knowledge and Attitudes Survey Regarding Pain, with a time delay of 8 to 12 days between testing. The expert nurses learned significantly more than the nonexpert nurses from pretest to post-test, M = 9.0 and M = 1.5 items, respectively. Expert and nonexpert nurses correctly answered 51.5% and 43.3% of the pretest and 74.6% and 47.2% of the post-test questions, respectively. Test-retest reliability for the 28 nonexpert nurses was r = 0.68, P < .001. Cronbach's alpha for the entire sample was 0.88 (n = 30) at the post-test. These results contribute to the validity and reliability of the Greek version of the Nurses' Knowledge and Attitudes Survey Regarding Pain and provide the basis for phase II of the study, which will use the Nurses' Knowledge and Attitudes Survey Regarding Pain to examine the state of pain management in an anticancer facility in Greece.
