This study investigated the impact of social stress on symptoms of psychopathology at the entry into adolescence (111 girls, Mage=11.84, SD=0.77). We examined whether peer stress and pubertal timing were associated with internalizing distress and aggression, and whether responses to stress and cortisol reactivity mediated or moderated these associations. Cortisol samples were collected from saliva samples during in-home visits, and the YSR was used to assess psychopathology. Interestingly, pubertal timing demonstrated a trend association with cortisol. Responses to stress mediated the association between social stress and symptoms of internalizing distress and aggression. Specifically, early maturers and girls with higher levels of peer stress exhibited more problematic responses to stress, in turn demonstrating higher levels of internalizing distress and aggression. Significant moderation effects also emerged. For example, early maturers who experienced higher levels of emotional/cognitive numbing in response to peer stress were at greater risk for aggression. Findings identify coping strategies that may be used in evidence-based programming to help girls transition more successfully into adolescence will be discussed.
KeywordsPeer stress; Coping; Pubertal timing; Internalizing; Aggression Adolescence represents a period for developing skills-interpersonal as well as personal. However, as consistent with the diathesis-stress model, some individuals enter adolescence with prior vulnerabilities (poorer problem solving skills, less developed emotion regulation skills, difficulty with emotional expression, greater physiological reactivity) making it more challenging to adapt effectively to the quickly changing landscape of early adolescence (Igram and Luxton 2005). As time spent with peers increases during the transition into adolescence, so does the likelihood of experiencing negative peer interactions, such as victimization by peers (via both overt and relational aggression), interpersonal problems © Springer Science + Business Media, LLC 2008 Correspondence to: Lisa M.

Based on prior vulnerabilities and prior experiences, adolescents often respond to such negative peer events with a range of reactions-anger, sadness, aggression, emotional suppression, etc. In turn, how an adolescent adapts to these experiences is often associated with the expression of emotional and behavioral problems (Compas et al. 2001).Much of the research examining how children and adolescents manage and adapt to stressful experiences demonstrates that coping strategies or responses to stress, more broadly, may buffer the effects of stressful experiences, ultimately reducing the likelihood of subsequent psychosocial problems (Jaser et al. 2005;Wadsworth et al. 2005). However, the stress and coping literature also suggests that the stressful situation...
