Prospective Associations between Peer Aggression and Victimization: The Moderating Roles of Physiological Stress Reactivity and Gender

The present investigation examined whether heightened skin conductance reactivity (SCLR) to peer stress strengthened the prospective associations between physical and relational aggression and victimization, and whether associations were stronger for physical forms of aggression and victimization among boys and relational forms of aggression and victimization among girls. A total of 91 children [M age = 10.18 years, standard deviation (SD) = .68] were assessed twice over 1 year. At the first assessment, SCLR in response to recounting a relational stressor (e.g., exclusion; SCLR‐R) and an instrumental stressor (e.g., property theft; SCLR‐I), and teacher‐reported aggression were measured. Parents reported on child victimization at both time points. Among youth with heightened SCLR‐I, physical aggression was associated with increases in physical victimization for boys and decreases in physical victimization for girls. Among youth with heightened SCLR‐R, relational aggression was associated with increases in physical victimization for girls only. Results were largely consistent with the hypothesis that aggressors with a propensity to exhibit negative displays of emotion, as indexed by heightened sympathetic nervous system (SNS) reactivity to peer stress, may be especially likely to suffer peer victimization. Gender‐specific effects highlight the importance of including both physical and relational forms of aggression and victimization to capture victimization risk among aggressive boys and girls.     

Someone to Lean on: Assessment and Implications of Social Surrogate Use in Childhood

A social surrogate is a person who helps a shy individual deal with the stresses of a social situation. Previous research has only investigated social surrogate use in adults. The purpose of the current study was to develop and evaluate a new self‐report measure of social surrogacy in middle childhood and to explore the implications of this phenomenon for children's socioemotional functioning. Participants were N = 328 children in grades 3–5 (Mean_age= 9.45, Standard deviation = .93). Children completed the newly developed child social surrogate questionnaire (CSSQ) as well as self‐report assessments of shyness, loneliness, social anxiety, peer victimization, and self‐perceptions. Results indicated good psychometric properties and evidence of construct validity for the CSSQ. Social surrogacy was related to elevated shyness, social anxiety, and victimization. Contrary to expectations, there was also some evidence to suggest that social surrogacy may have particularly negative implications for shy children.     

Gay‐Straight Alliances,Inclusive Policy,and School Climate: LGBTQ Youths’ Experiences of Social Support and Bullying

Gay‐Straight Alliances (GSA) and school policies focused on support for lesbian, gay, bisexual, transgender, and queer/questioning youth may reduce bias‐based bullying and enhance social supports in schools. Using multivariate regression, we tested the relationship between youth reports of the presence of GSAs and LGBTQ‐focused policies, independently and mutually, with experiences bullying and perceived support (n = 1,061). Youth reported higher classmate support in the presence of GSAs and higher teacher support in the presence of LGBTQ‐focused policies; the presence of both GSAs and LGBTQ‐focused policies was associated with less bullying and higher perceived classmate and teacher support. The findings indicate that GSAs and LGBTQ‐focused policies are distinctly and mutually important for fostering safer and more supportive school climates for youth.     

Adolescents’ Subjective Social Status Predicts Day‐to‐Day Mental Health and Future Substance Use

Adolescents’ subjective social status (SSS) is associated with mental and behavioral health outcomes, independent of socioeconomic status (SES). Many previous findings, however, come from cross‐sectional studies. We report results from a longitudinal study with 151 adolescents identified as at risk for early substance use and behavioral problems sampled from low‐SES neighborhoods. We examined whether adolescent's SSS predicted mental health (depression, anxiety, and inattention/impulsivity) measured over 30 days via ecological momentary assessment and risk for substance use at an 18‐month follow‐up. Results showed that with each perceived step “up” the SSS ladder, adolescents experienced fewer mental health symptoms in daily life and lower future substance use risk after adjusting for objective SES and previous psychopathology. Implications of these findings are discussed.

ON CONSUMER- VERSUS FIRM-LEVEL ANALYSIS OF ADVERTISING EFFECTIVENESS: IMPLICATIONS FOR MODEL BUILDING*

Issues relating to the construction of marketing models are discussed. These include determining the level of aggregation of model construction, specifying the structure of the model, and the aggregation level of data to be employed in estimating model parameters. These issues are addressed through specifying and estimating both consumer-level and firm-level models and comparing the results. An important conclusion is that inferences about consumer behavior should not be drawn from firm-level models since aggregation bias may exist.
