Turkish validity and reliability of Burnout Syndrome Assessment Scale for Nurses Working in intensive care units

The aim is to adapt the Burnout Syndrome Assessment Scale for Nurses Working in Intensive Care Units to the Turkish version and determine its validity and reliability.

Methods:
Methodological study design was used. The instrument was translated into Turkish and back- translated into English. The scale’s language equivalence, content validity, test-retest reliability, internal consistency, and construct validity were evaluated. The research was conducted with 200 intensive care nurses at a university hospital who volunteered to participate. Internal consistency was analyzed using Cronbach's alpha and item analysis, while construct validity was assessed via confirmatory factor analysis. Time-dependent invariance was determined through the test-retest Method with 150 intensive care nurses at two-week intervals, calculating intraclass correlations. The number, percentage distributions, intraclass correlation coefficient (ICC), Kappa coefficient test, and Mann‒Whitney U test were used to analyze the data.

Results:
Twelve experts evaluated content validity, and the content validity index (CVI) ranged between 0.833 and 1.000, which is higher than the generally accepted standard level. Three dimensions were obtained according to the eigenvalues in the first-factor analysis Results. Still, since most of the items related to the scale were explained over a single dimension, the factor analysis application was carried out over a single dimension. Maslach Burnout Scale was used for the inter-reliability of parallel forms. The questionnaire's overall internal consistency coefficient (Cronbach's Alpha) was highly reliable, with a value of 0.95.

Conclusion:
The Burnout Syndrome Assessment Scale for Nurses Working in Intensive Care Units is a valid and reliable instrument for intercultural studies.
