School connectedness is an important feature to consider within the school environment because it likely accounts for why some youth thrive and others struggle with internalizing problems. Furthermore, internalizing problems typically do not occur in isolation of each other, but rather anxiety and depressive symptoms frequently co-occur and increase subsequent risk for each other. As such, the primary study objectives were to (a) evaluate the bidirectional relationships between school connectedness and internalizing symptoms and (b) examine whether being at high risk of an anxiety disorder or major depression moderated these relationships. Adolescents attending public middle schools ( N = 1,344; 11-14 years; 51% female; 52% White) completed surveys in school at baseline and at a 6-month follow-up. Baseline anxiety disorder risk status moderated the relationships between school connectedness and internalizing symptoms. Among adolescents at low risk of an anxiety disorder, higher baseline school connectedness predicted improvements in depressive symptoms and, conversely, higher baseline depressive symptoms predicted lower school connectedness. School connectedness and depressive symptoms were unrelated among adolescents at high risk of an anxiety disorder. There were no significant associations between school connectedness and anxiety symptoms, regardless of baseline risk for major depression. Implications for school-based intervention strategies are discussed, such as fostering school connectedness and screening for internalizing problems.

Appearance-related teasing is a pervasive form of bullying during adolescence. Yet, the impact of appearance-related teasing on risk for alcohol and marijuana use is unknown. This study, therefore, examined the relationship between appearance-related teasing and the use of alcohol and marijuana in a sample of 1,344 students (52% female; 51% non-Hispanic White; ages 11-14 years, M ϭ 13.20, SD ϭ 0.65) from 5 public middle schools. Participants completed a survey that assessed demographic characteristics, weight status, depressive symptoms, general peer victimization, experiences of appearancerelated teasing perpetrated by family and peers, and substance use in the fall of 2016 (Time 1 [T1]) and spring of 2017 (T2). Findings at baseline (T1) indicated that more frequent appearance-related teasing was associated with higher concurrent levels of total alcohol consumption, binge drinking, and marijuana use (ps Ͻ .001). Longitudinally, more frequent appearance-related teasing at T1 predicted greater increases in total alcohol consumption (p Ͻ .01) and binge drinking frequency (p Ͻ .05) by T2 but was unrelated to changes in marijuana use (p Ͼ .05), adjusting for age, gender, race and ethnicity, perceived socioeconomic status, body mass index z scores, depressive symptoms, general peer victimization frequency, and substance use at T1. Moderation analyses generally suggested that the positive associations between appearance-related teasing and alcohol use measures were stronger among adolescents who were girls (vs. boys) and who were overweight or obese (vs. nonoverweight). These findings suggest that appearance-related teasing may play a role in the origins of alcohol use during early adolescence and emphasize the need to mitigate the effects of appearance-related teasing and prevent early substance use.
