中文摘要：

本研究旨在考查不同群体（本地、外地）青少年朋友选择的特点，以及跨群体友谊与群际态度的关系，同时考查了群际焦虑在跨群体友谊与群际态度之间的中介作用。905名初中学生参与了本次调查．测量工具包括朋友提名（友谊数量和质量）、群际态度（积极情感与消极刻板印象）和群际焦虑量表。结果发现：（1）在本地与外来学生混合的学校中，跨群体友谊普遍存在，且外地学生在选择朋友时存在一定的本群体偏好；（2）跨群体友谊与更为积极的外群体态度相关联，且这种“友谊效应”只存在于外地学生中；（3）跨群体友谊通过群际焦虑的中介作用对群际态度产生影响。

英文摘要：

The current study examined friendship selection patterns among different groups （ i. e. , local and immigrant） of adolescents, the link between cross-group friendships and intergroup attitudes, and the mediation role of intergroup anxiety in attitude change. 905 middle school students participated in the study. Measures of friendship （quantity and quality）, intergroup attitudes （affect and cognitive） and intergroup anxiety were assessed. Results indicated that ： （ 1 ） Cross-group friendships were common in school settings, while some immigrant students showed own-group preference when choosing friends; （2） Cross-group friendships were related to better intergroup attitudes, and this friendship effect was only found among immigrant students; （3） Intergroup anxiety mediated the link between cross-group friendships and intergroup attitudes.
