BACKGROUND Ostracism -being ignored and excluded- entails risks for adolescent mental health. Less is known about the factors that are negatively associated with the adverse consequences of ostracism. This study explored the association between dispositional mindfulness and need threat following social exclusion using the Cyberball paradigm. Sex and age were included as moderators of the relationship between dispositional mindfulness and need threat. Additionally, the factor structure of the Need Threat Scale (NTS) was analyzed in Spanish adolescents. METHOD Participants (N = 750, 52.4% female; mean age = 14.51) completed a mindfulness questionnaire, were ostracized in the Cyberball game, and reported their need threat during this game. RESULTS Dispositional mindfulness was negatively associated with need threat only in older adolescents (>15 years old). Although girls reported higher levels of need threat than boys, sex did not moderate the association between mindfulness and need threat. CONCLUSIONS This research suggests that dispositional mindfulness is only associated with NTS in older adolescents and girls are more vulnerable to the negative consequence of ostracism.

西班牙青少年排斥后的性格正念与需求威胁之间的关联：年龄的调节作用。

背景 排斥——被忽视和排斥——会给青少年心理健康带来风险。关于与排斥的不利后果负相关的因素知之甚少。本研究使用 Cyber​​ball 范式探讨了性格正念与社会排斥后需求威胁之间的关联。性别和年龄被列为性格正念与需求威胁之间关系的调节因素。此外，对西班牙青少年的需求威胁量表 (NTS) 的因子结构进行了分析。方法 参与者（N = 750，52.4% 女性；平均年龄 = 14.51）完成了一份正念问卷，在 Cyber​​ball 游戏中被排斥，并在游戏中报告了他们的需求威胁。结果 仅在年龄较大的青少年中，性格正念与需求威胁呈负相关（> 15岁）。尽管女孩报告的需求威胁程度高于男孩，但性别并未缓和正念与需求威胁之间的关联。结论 这项研究表明，性格正念只与年龄较大的青少年的 NTS 相关，而女孩更容易受到排斥的负面后果的影响。
