Schröder 31 University of Mannheim, Germany; 2 SHARE MEA University of Mannheim, Germany; 3 Mannheim Centre forEuropean Social Research MZES, University of Mannheim, GermanyMost large longitudinal surveys are designed either as individual surveys or as household surveys. For a studyof families and inmate relaonships though, a design that allows the analysis of dyads of people irrespec-ve of their living arrangements is to be preferred. With such a design specific research quesons can beaddressed, for example living-apart-together partnership arrangements or forms of intergeneraonal supportin both direcons between parents and their grown-up children outside the household.2.18 Measurement validity and reliability in cross-cultural comparison ITo be held on July 20, 2011 from: 11:00 to 12:30, in room 321.Coordinated by:• María-Dolores Hidalgo - University of Murcia, Spain• Jan Dietrich Reinhardt - University of Lucerne, Switzerland2.18.1 Analysing DIF in Polytomous Items by Mantel-Haenzsel and Ordinal logisc regression: An applica-on with PISA atudinal quesonnairesI. Benítez 1 , J. Padilla 1 , M. Hidalgo 3 , S. Sireci 21 University of Granada, Spain; 2 University of Massachuses, United States; 3 University of Murcia, SpainDifferenal Item Funconing (DIF) has received increased aenon by professionals and researchers interestedin internaonal and cross-cultural assessments over the last few decades. DIF analyses can providevalidity evidence of the equivalence level reached by different linguiscs or cultural versions of scale items.There are a wide variety of stascs for detecng DIF in both dichotomous and polytomous items. Fewerstudies have researched into ways of applying DIF stascs to detect DIF in atudinal polytomous items forcross-linguisc or cultural comparisons.The aim of this study was to illustrate how to detect polytomous DIF byMantel-Haenzsel and Ordinal Logisc Regression (OLR) procedures. DIF across English and Spanish versions ofthe seven scales included in the Student Quesonnaire of the Program for Internaonal Student Assessment(PISA, OECD, 2006), was analyzed...2.18.2 The detecon of Differenal Item Funconing in short test: A comparison of LR analysis to IRTLRDIFtechnique.M. Hidalgo 3 , M. López 3 , J. Gómez Benito 1 , J. Padilla 21 University of Barcelona, Spain; 2 University of Granada, Spain; 3 University of Murcia, SpainThere are a growing number of cross-cultural and internaonal surveys in the last decade. The comparisonof psychological and sociological variables through different cultural and linguisc groups is the aim of an increasingnumber of studies. Survey researchers usually compare measures provided by different cultural orlinguisc versions of quesonnaires. To make valid comparison involve first to have developed a carefullytranslaon process, and secondly, to test the level of equivalence reached. The analysis of Differenal ItemFunconing (DIF) is required to test whether the level of metric equivalence has been reached. Test length canaffect the right flagging items with DIF. This paper compares by a simulaon study the effecveness of LogiscRegression analysis and IRTLRDIF for detecng DIF in short tests...2.18.3 How much DIF make total-group score comparisons invalid?J.
