Adolescents who lack friends at school are at risk of internalizing difficulties. This study examined a social‐cognitive mechanism underlying friendlessness and internalizing difficulties (i.e., depressive symptoms, social anxiety, low self‐esteem). We tested whether perceived social threat (i.e., peer victimization, sense of unsafety, and peer misconduct) mediates the association between friendlessness and increased internalizing difficulties across middle school. Latent variable structural equation modeling was used to test the model among an ethnically diverse sample of 5,991 (52% female) adolescents. The results demonstrate that friendless sixth‐grade students perceived their school environment as more threatening by seventh grade, which in turn, increased internalizing difficulties from sixth to eighth grade. Perceptions of threat also predicted friendlessness at the end of middle school.
