An Examination of the Validity and Reliability of the Turkish Version of the Nurses’ Attitudes toward Obesity and Obese Patients (Natoops) Scale

Abstract

Purpose: The aim of this study was to examine the validity and reliability of the Turkish version of the Nurses’ Attitudes toward Obesity and Obese Patients (NATOOPS) Scale, and to provide a scale to be used in this area in Turkey. Method: Forward-backward translation of the NATOOPS from English to Turkish. The translated instrument administered 360 nurses working in the internal medicine and surgery clinics of a university hospital in Izmir, Turkey. The size of the sample was arranged so as to be ten times the number of items on the scale. A Nurses’ Identification Form and the NATOOP) Scale were used as instruments to collect data. Result: Construct validity was tested by factor analysis. The Cronbachalpha coefficient the test-retest reliability coefficient and the item-total correlation were calculated. The scale was applied to 30 nurses twice, at the start and after two weeks. The views of 13 experts were sought on content validity, and their scores in the analysis were found to be compatible (KW=0.159, p=0.08). The Cronbachalpha coefficient obtained for the whole scale was 0.92. In the item analysis, the item-total correlation coefficient of items on the scale varied between 0.46 and 0.91, and no item was removed from the scale as a result. When test-retest was applied to test the invariability of the scale over time, a single factor was obtained explaining 74.17% of the total variance of the scale
