Validaty and Reliability of the Turkish Version of the Utrecht Grief Rumination Scale
Abstract
The aim of this study is to adapt Utrecht Grief Rumination Scale, validity and reliability studies of which have already been done abroad, to Turkish culture. For the validity of the scale, Confirmatory Factor Analysis (CFA) were performed and the Core Bereavement Items was used for criterion validity. Among the reliability tests, material statistics and Cronbach's alpha coefficients were used. In order to test the invariance of time, the scale was applied to the same sample at four weeks intervals. It was found that x2/Sd, CFI, IFI, RMSEA, SRMR, PNFI and PGFI model fit indices were in good level. A statistically significant, positive and linear relation was found between The Core Bereavement Items and UGRS. The item-scale total correlation values of all items were above .30. The Cronbach's alpha value of the UGRS was .94 and the Cronbach's alpha of the sub-dimensions ranged from .80 to .89. A positive directional linear relationship was found between pre-test and post-test measurements to determine the invariance of UGRS (r =.89; p=.000). Conclusion: As a result, it was determined that UGRS was valid and highly reliable and did not show any change in time.
