Abstract:
The purpose of this study was to test the psychometric properties of the Nursing Teamwork Survey-Icelandic (NTS-Icelandic), which was translated from US English to Icelandic. The Nursing Teamwork Survey, with 33 items, measures overall teamwork and five factors of teamwork: trust, team orientation, backup, shared mental models, and team leadership. The psychometric testing of the NTS-Icelandic was carried out on data from a pilot study and a national study. The sample for a pilot study included 123 nursing staff from five units, and the sample for a national study included 925 nursing staff from 27 inpatient units. The overall test-retest intraclass correlation coefficient in the pilot study was 0.693 (lower bound = 0.498, upper bound = 0.821) (p < 0.001). The Cronbach's alpha reliability for the total scale and subscales ranged from 0.737 to 0.911. A confirmatory factor analysis indicated a good fit of the data from the national study with the five-factor model for nursing teamwork. The NTS-Icelandic tested valid and reliable in this study. Study findings support further use of the Nursing Teamwork Survey internationally.
