    <r:Abstract>
      <r:Content xml:lang="de">&lt;p align="justify"&gt;Der Datensatz wurde im Rahmen des Forschungsprojekts „Freundschaft und Identität in der Schule" erstellt, mit dem Ziel, die Verbindung zwischen den sozialen Freundschaftsbeziehungen von Jugendlichen und ihrer ethnischen Identifikation zu erforschen (Leszczensky et al. 2014). Der Datensatz umfasst longitudinale Informationen von bis zu sechs Erhebungswellen an zehn Schulen im Bundesland Nordrhein-Westfalen, das für seinen hohen Anteil an Schüler:innen mit Migrationshintergrund bekannt ist. Die Schulen, die verschiedene Bildungsniveaus repräsentieren (Hauptschule, Realschule und Gesamtschule), wurden zufällig ausgewählt, basierend auf dem Anteil an Schüler:innen mit Migrationsbiographie. In jeder Schule wurden drei Jahrgangsstufen befragt. Die Studie begann 2013 mit den fünften, sechsten und siebten Klassen und erstreckte sich über sechs Erhebungswellen, die ungefähr neun Monate auseinander lagen. Die Teilnahme erforderte schriftliche Zustimmung der Eltern. Der Datensatz umfasst 2.928 Schüler:innen, die in 29 Jahrgangsstufen und 95 Klassen eingebettet sind und potenziell an jeder Erhebungswelle teilnehmen konnten. Davon nahmen mindestens einmal 2.701 Schüler:innen teil. Die Antwortraten waren konstant hoch und betrugen durchschnittlich fast 85 Prozent pro Welle, mit einer Panel-Antwortrate von fast 90 Prozent. Um das Zusammenspiel zwischen Freundschaftsnetzwerken und ethnischer Identifikation zu erforschen, enthält der Datensatz soziometrische Fragen, die die Freundschaftsnetzwerke der Schüler:innen erfassen, sowie eine neuartige Messung der ethnischen Identifikation. Neben den Freundschaftsdaten enthält der Datensatz Informationen zu Demografie, Freizeitaktivitäten, schulischer Leistung, musikalischen und sportlichen Vorlieben, wahrgenommener Diskriminierung, Einstellungen, Religion, familiären Situationen, Kontaktmöglichkeiten und elterlichen Meinungen. Dieser umfassende Datensatz eignet sich für eine breite Palette von Forschungsfragen, die über die ursprüngliche Forschungsfrage der Studie hinausgehen.&lt;/p&gt;</r:Content>
      <r:Content xml:lang="en">&lt;p align="justify"&gt;The dataset was collected as part of the study "Friendship and Identity in School," with the aim of investigating the relationship between adolescents' friendship networks and their ethnic identification (Leszczensky et al. 2014). The dataset includes longitudinal information from up to six waves of data collection at ten schools in the German federal state of North Rhine-Westphalia, known for its high percentage of students with a migration background.
The schools, representing various educational levels (lower secondary, intermediate secondary, and comprehensive), were randomly selected based on the proportion of non-native students. Within each school, three grades were surveyed. The study began in 2013 with the fifth, sixth, and seventh grades and spanned six waves approximately nine months apart. Participation required written parental consent. The dataset encompasses 2,928 students nested within 29 grades and 95 classrooms, all potentially eligible for participation in any wave. Of these, 2,701 students participated at least once. Response rates were consistently high, averaging nearly 85 percent per wave, with a panel response rate close to 90 percent. To explore the interplay between friendship networks and ethnic identification, the dataset includes sociometric questions capturing students' friendship networks and a novel measurement of ethnic identification. In addition to friendship data, the dataset contains information on demographics, leisure activities, academic performance, musical and sports preferences, perceived discrimination, attitudes, religion, family situations, contact opportunities, and parental opinions. This comprehensive dataset is suitable for a wide range of research inquiries that go beyond the study's initial research question.&lt;/p&gt;</r:Content>
