{"product_id":"9783631645727","title":"Psychometrically Relevant Differences between Source and Migrant Populations","description":"Psychometrically relevant population differences may limit the transferability of research instruments between migrants and their source population and may contribute to a low performance of quantitative questionnaires. Based on a review of existing taxonomies, this book develops a comprehensive analytical framework of equivalence that can serve multiple purposes. It allows to examine psychometrically relevant population differences, it can assist in the re-adaptation of questionnaires and it is a valuable tool for cross-group comparative research. The application of the framework is illustrated through the examination of equivalence of the Revised Illness Perception Questionnaire (IPQ-R) between chronically ill Turks residing in Turkey and Turkish migrants residing in Germany.","brand":"Peter Lang GmbH, Internationaler Verlag der Wissenschaften","offers":[{"title":"Default Title","offer_id":46358837657841,"sku":"9783631645727","price":25.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/5433\/7265\/files\/9783631645727_p0.jpg?v=1765302015","url":"https:\/\/shop.barnesandnoble.com\/products\/9783631645727","provider":"Barnes \u0026 Noble","version":"1.0","type":"link"}
