    The Validity and Reliability of A Turkish Version of The Poverty-Related Quality of Life (Pqol) Questionnaire
    (2016) Yilmaz, Fikriye; 0000-0002-4884-3803; AAF-7789-2020
    Measuring poverty in health care settings may help to identify patients living in poverty and also support development of appropriate policies to reduce health inequalities. The objective of this study was to translate the Poverty-Related Quality of Life Questionnaire into Turkish and then test its validity and reliability for a Turkish patient population. The psychometric properties of the scale were examined by collecting data from 300 patients in emergency departments in three randomly selected hospitals in Ankara, Turkey. The results of the study suggest that the Turkish version of the Poverty-Related Quality of Life Questionnaire has satisfactory validity and reliability.

    Linguistic Distance and Translation Differential Item Functioning on Trends in International Mathematics and Science Study Mathematics Assessment Items
    (2021) Gokce, Semirhan; Berberoglu, Giray; Wells, Craig S.; Sireci, Stephen G.
    The 2015 Trends in International Mathematics and Science Study (TIMSS) involved 57 countries and 43 different languages to assess students' achievement in mathematics and science. The purpose of this study is to evaluate whether items and test scores are affected as the differences between language families and cultures increase. Using differential item functioning (DIF) procedures, we compared the consistency of students' performance across three combinations of languages and countries: (a) same language but different countries, (b) same countries but different languages, and (c) different languages and different countries. The analyses consisted of the detection of the number of DIF items for all paired comparisons within each condition, the direction of DIF, the magnitude of DIF, and the differences between test characteristic curves. As the countries were more distant with respect to cultures and language families, the presence of DIF increased. The magnitude of DIF was greatest when both language and country differed, and smallest when the languages were same, but the countries were different. Results suggest that when TIMSS results are compared across countries, the language- and country-specific differences which could reflect cultural, curriculum, or other differences should be considered.
