Prospective associations between peer support, academic competence, and anxiety in college students.

Previous literature has demonstrated that peer support is instrumental for the promotion of adaptive academic and mental health outcomes; however, limited research has examined prospective directional associations between peer support and adjustment within college settings. The purpose of this study was to investigate the longitudinal associations between peer support, academic competence, and anxiety among U.S. college students. U.S. students from a diverse 4-year university (N = 251, 75% women, 24% men, and < 1% a different gender) reported on peer support, academic competence, and anxiety using validated questionnaires at two time points (Fall term of sophomore year and Spring term of senior year). Results showed that peer support was positively associated with academic competence over time but was not significantly related to future anxiety. Academic competence did not significantly predict peer support or anxiety over time, but anxiety was associated with lower future academic competence. These findings offer insight into how types of social relationships link with academic motivation and anxiety over time within educational settings.

Fostering School Belonging and Students' Well-Being Through a Positive School Interethnic Climate in Diverse High Schools.

BACKGROUND: School belonging has been linked to students' health and well-being. As US schools become more ethnically diverse, it is important to understand how schools can contribute to a sense of belonging for students from all ethnic groups. METHODS: The present study examines the association between school interethnic climate, school belonging, and 3 well-being indicators (psychological, physical, and academic) among 657 10th graders across 2 states. RESULTS: Positive school interethnic climate was associated with stronger feelings of school belonging, and was indirectly associated with better psychological adjustment, fewer physical symptoms, and better grades via school belonging. There were no differences between White and non-White students in the findings. CONCLUSIONS: Focusing on fostering a positive interethnic atmosphere may be a useful target for schools to support students' health and well-being as well as academic performance.

Comparisons of school and home-packed lunches for fruit and vegetable dietary behaviours among school-aged youths.

OBJECTIVE: School-based interventions and policies encourage youths to include and consume fruits and vegetables at lunchtime via school lunches, but limited research has examined how these behaviours compare when youths have home-packed lunches. The objective of the present study was to compare fruit and vegetable contents and consumption among students having school or home-packed lunches over the school week. DESIGN: Participants were observed over five consecutive days at school lunchtime. Trained analysts estimated students' lunchtime fruit and vegetable contents and consumption using digital imaging. Mixed models examined associations between fruit and vegetable dietary behaviours and lunch source (school v. home-packed), controlling for student gender, grade and school. SETTING: Three elementary schools in northern California, USA.ParticipantsFourth-, fifth- and sixth-grade students (nchildren 315; nobservations 1421). RESULTS: Students were significantly less likely to have and to consume fruits and vegetables (all P<0·05) when having home-packed lunches, compared with when having school lunches. Among those who did have or did consume these foods, having a home-packed lunch was associated with consuming significantly less fruit (P<0·05) but no differences for other dietary outcomes. CONCLUSIONS: The study adds to a growing body of literature indicating shortfalls in fruit and vegetable contents and consumption associated with having a home-packed lunch, relative to having a school lunch. Findings suggest that school-based interventions, particularly when targeting home-packed lunches, should focus on whether or not these foods are included and consumed, with less emphasis on quantities.

Discrepancies Between Retrospective and Actual Self-Reports of Peer Victimization Six Years Earlier.

Retrospective peer victimization reports may be inaccurate. With an ethnically and sexually diverse sample, this study compared adolescents' self-reported peer victimization in 6th grade to their own retrospective reports of 6th-grade victimization when they were in the 12th grade, controlling for past and current adjustment. Overall, 12th graders' retrospective victimization reports correlated with their own earlier 6th-grade self-reports and there was a general tendency to underreport retrospectively. Underreporters were distinguished by worse past 6th-grade adjustment, whereas overreporters were distinguished by worse current (12th-grade) adjustment. Higher current depressive symptoms and social anxiety, and lower current self-worth may be important control variables when collecting retrospective reports of victimization because current adjustment may augment participants' recollection of past experiences.

Parental and family predictors of fruits and vegetables in elementary school children's home-packed lunches across a school week.

Home-packed lunches have been found to be of lower nutritional quality than school-bought lunches, yet little is known about family-based factors associated with lunch packing. The current exploratory study examines parental and family predictors of fruits and vegetables packed in lunches, hypothesizing parents' nutrition knowledge and authoritative parenting as well as children's involvement in lunch decisions would relate to packing more fruits and vegetables, while financial difficulties would relate to packing fewer. Ninety parent-child dyads from 4th-6th grade participated for 5 consecutive school days. Lunch contents were recorded using a digital imaging procedure to capture the number of days a fruit or vegetable was packed, and servings of fruits and vegetables in lunches each day. Parents completed family and parenting questionnaires and daily reports of child involvement in lunch decisions. Count-based regression models and longitudinal analyses within a multilevel modeling framework were used to examine predictors of lunch contents. Higher nutrition knowledge was associated with packing more fruit across the week and more vegetables on Monday. Authoritative parenting was associated with packing fewer vegetables on Monday, but more servings across the week. Financial stress was related to higher rates of never packing vegetables and when vegetables were packed including fewer servings, while child involvement in lunch decisions was associated with packing more fruits across the week, packing vegetables on more days and more servings of vegetables on Monday. Findings suggest parental and family factors impact the foods in packed lunches, with implications for children's dietary intake at school. Outreach programs can help parents pack more fruits and vegetables by providing nutrition education and suggestions for affordable, healthy lunch options as well as encouraging child involvement in the lunch packing process.

Feasibility and reliability of digital imaging for estimating food selection and consumption from students' packed lunches.

Although increasing attention is placed on the quality of foods in children's packed lunches, few studies have examined the capacity of observational methods to reliably determine both what is selected and consumed from these lunches. The objective of this project was to assess the feasibility and inter-rater reliability of digital imaging for determining selection and consumption from students' packed lunches, by adapting approaches previously applied to school lunches. Study 1 assessed feasibility and reliability of data collection among a sample of packed lunches (n = 155), while Study 2 further examined reliability in a larger sample of packed (n = 386) as well as school (n = 583) lunches. Based on the results from Study 1, it was feasible to collect and code most items in packed lunch images; missing data were most commonly attributed to packaging that limited visibility of contents. Across both studies, there was satisfactory reliability for determining food types selected, quantities selected, and quantities consumed in the eight food categories examined (weighted kappa coefficients 0.68-0.97 for packed lunches, 0.74-0.97 for school lunches), with lowest reliability for estimating condiments and meats/meat alternatives in packed lunches. In extending methods predominately applied to school lunches, these findings demonstrate the capacity of digital imaging for the objective estimation of selection and consumption from both school and packed lunches.

Developmental Change in Sibling Support and School Commitment Across Adolescence.

School commitment typically declines across adolescence, but the family-level factors that explain this decline have not been fully characterized. This study investigated sibling support as a family resource in predicting school commitment across 7th-10th grade using a sample of 444 adolescents (Mages  = 12.61, 13.59, 14.59, 15.58 years). Results showed that sibling support linearly increased and school commitment decreased and stabilized, independently, over time. Sibling support positively predicted school commitment in seventh grade and across time, suggesting that having supportive siblings may help to offset adolescents' declines in school commitment. Furthermore, having a brother enhanced this association versus having a sister. These findings provide insight into ways to help youth maintain school commitment across the middle- to high school transition.

Mismatches in Self-Reported and Meta-Perceived Ethnic Identification across the High School Years.

Ethnic identification (i.e., one's self-reported ethnicity) is a social construction and therefore subject to misperceptions by others. When adolescents' self-views and others' perceptions are not aligned, adolescents may experience adjustment challenges. The present study examined mismatches between adolescents' ethnic identification (i.e., self-reported ethnicity) and meta-perceptions (i.e., what ethnicity they believed their schoolmates presumed them to be), as well as longitudinal associations between mismatches and adjustment across the high school years. Participants (Mage = 14.5; 57% girls) were an ethnically diverse sample of 1151 low-income high school students who had participated in an earlier longitudinal study during middle school. Although ethnic identification was largely consistent across the high school years, many students (46%) experienced at least occasional mismatches between their self-reported ethnic identification and meta-perceptions, with students who ever identified as multiethnic experiencing more mismatches than their monoethnic counterparts. Experiencing a mismatch was associated with more depressive symptoms, physical symptoms, and lower self-worth.

Early Adolescents' Peer Experiences with Ethnic Diversity in Middle School: Implications for Academic Outcomes.

As the U.S. becomes increasingly ethnically diverse, opportunities for cross-ethnic interaction at school may be increasing, and these interactions may have implications for academic outcomes for both ethnic minority and White youth. The current study examines how cross-ethnic peer relationships, measured using peer nominations for acceptance and daily lunchtime interactions, relate to academic outcomes for an ethnically diverse sample of 823 (45% boys and 55% girls; M age = 11.69) public middle school sixth graders across one Midwestern and two Western states. For White, Black, Asian, Latino/a, and Multiethnic students, self-reported daily cross-ethnic peer interactions were associated with higher end-of-year GPAs in core academic courses and teachers' expectations for educational attainment, but not self-reported school aversion. Making cross-ethnic acceptance nominations was not associated with any academic outcomes. Thus, daily opportunities for cross-ethnic interactions may be important school experiences for early adolescents.

Associations Between Adolescents' Weight and Maladjustment Differ With Deviation From Weight Norms in Social Contexts.

BACKGROUND: In line with the reflected self-appraisal hypothesis, previous research finds associations between weight and maladjustment are strongest when there is a mismatch between individuals' weight and the weight norm of their social contexts. However, research has not considered associations in more proximal social contexts. We examined differences in associations between weight and maladjustment for 2 proximal social contexts: grade-level peers and friendship groups. METHODS: We used sixth-graders (N = 565; Mage = 12 years) self-reported height and weight (used to calculate body mass index (BMI) z-score), experiences of peer victimization, and depressive symptoms. Deviation from the normative weight was calculated as the students' BMI z-score minus the average BMI z-score for the context (grade-level peers or friendship group). RESULTS: Considering deviations from grade-level peers, greater BMI z-scores were associated with more self-reported peer victimization only for students above the weight norm. For the friendship group, greater weight was associated with more self-reported depressive symptoms only for those who were above the normative weight. CONCLUSIONS: Being heavier during adolescence may be especially problematic for students who differ from the norm in their proximal social contexts. Intervention efforts focused on weight and maladjustment may want to consider the contexts involved in adolescents' self-appraisals.

Nice Guys and Gals Finish Last? Not in Early Adolescence When Empathic, Accepted, and Popular Peers are Desirable.

Little is known about attributes that elicit romantic desirability in early adolescence. The current study, with a sample of 531 sixth-grade students (45% boys) attending ethnically diverse middle schools, used a resource control framework to explore which self-reported behaviors (e.g., empathy and aggression) and peer-reported status (e.g., acceptance and perceived popularity) predict the likelihood of being considered romantically desirable (i.e., receiving at least one "crush" nomination from an opposite sex grademate). Self-reported empathy was positively associated with students' romantic desirability (primarily for those with high peer acceptance), whereas self-reported aggression on its own did not. Both peer-acceptance and popularity also were positively associated with students' romantic desirability, and aggressive behavior reduced popularity's effect. Although aggression may be integral for obtaining high peer status across cultures, prosocial behaviors were romantically valued. Our findings suggest that peer-vetted social status elicits romantic interest and during early adolescence, nice guys and gals really do not finish last.

How you look versus how you feel: Associations between BMI z-score, body dissatisfaction, peer victimization, and self-worth for African American and white adolescents.

Being overweight and having negative self-perceptions (body dissatisfaction) can have problematic consequences for adolescents physically, socially, and psychologically. Understanding associations between weight, self-perceptions, and peer experiences across ethnicities is particularly important given recent increases in obesity among ethnic minorities. The current study aimed to address these issues by examining Body Mass Index (BMI) z-scores and body dissatisfaction predicting change in general self-worth over time via peer victimization experiences in a diverse sample of 236 youth (ages 10-16 years). Body dissatisfaction predicted decreases in self-worth over time even after controlling for BMI z-score. BMI z-scores predicted decreases in self-worth over time only for white adolescents, whereas body dissatisfaction directly predicted decreases in self-worth for African American youth and indirectly via peer victimization for white youth. Associations were also considered by gender. Implications for intervention efforts for both white and African American adolescents are discussed.

A longitudinal study of body dissatisfaction and pubertal timing in an ethnically diverse adolescent sample.

In a 7-year study, adolescents' body dissatisfaction (N=1370) was examined across four high school years as a function of pubertal development (perceived timing relative to peers and self-reported physical changes measured during Grades 6-10) in the context of the high school transition. Boys and girls who, during early high school, perceived themselves to be late relative to peers were at risk for body dissatisfaction across the high school years. Boys who were late in pubertal development reported more body dissatisfaction in early high school than on-time boys, but then decreased over time. African-American girls reported less body dissatisfaction across the high school years relative to other girls. Asian girls reported more dissatisfaction in early high school than African-American, Latina, and Multiethnic girls, and increased over time. Results highlight the importance of considering late development within context as a risk factor in body dissatisfaction research.

Adolescent daily and general maladjustment: is there reactivity to daily repeated measures methodologies?

The present study examined whether repeated exposure to daily surveys about negative social experiences predicts changes in adolescents' daily and general maladjustment, and whether question content moderates these changes. Across a 2-week period, 6th-grade students (N = 215; mode age = 11) completed 5 daily reports tapping experienced or experienced and witnessed negative events, or they completed no daily reports. General maladjustment was measured in 2-week intervals before, at the end of, and 2 weeks after the daily report study. Daily maladjustment either decreased or did not change across the 5 daily report exposures. General maladjustment decreased across the three 2-week intervals. Combined, results indicate that short-term daily report studies do not place youth at risk for increased maladjustment.

Microcontextual characteristics of peer victimization experiences and adolescents' daily well-being.

Microcontextual factors (i.e., contextual characteristics of the specific victimization incident) may help to explain the association between adolescents' daily peer victimization experiences and well-being. In the present study, daily report methodology was used to assess sixth (N = 150; 53% girls) and ninth grade (N = 150; 50% girls) students' current well-being and peer victimization earlier in the day on 5 random school days within a 2-week period. Associations between peer victimization microcontextual factors (number of aggressors, presence of witnesses, and receipt of help) and fluctuations in adolescents' daily well-being (humiliation, worry, and physical symptoms) were examined in an ethnically diverse sample of White, Latino, Asian, African American, and multiethnic students. Humiliation increased on days in which students reported public victimization, multiple aggressors, and no help. Worry increased on days students experienced private victimization and when boys (but not girls) experienced private victimization, victimization by a single aggressor, and received peer help. Physical symptoms were higher on days that victimization occurred, regardless of context, but only for sixth graders and not ninth graders. These findings suggest that the victimization microcontext can offer insight about the types of peer victimization exposure that might produce the greatest daily risk for adolescents.

School context protective factors against peer ethnic discrimination across the high school years.

Ethnically diverse high school contexts present unique social opportunities for youth to form interethnic relationships, but they may also subject students to certain social challenges such as peer ethnic discrimination. With a sample of 1,072 high school students (55% girls; 54% Latino, 20% African American, 14% Asian, 12% White) attending 84 high schools, school context factors that protect students' exposure to peer ethnic discrimination across the high school years were investigated with a three-level hierarchical linear model. Each spring for four consecutive years (grades 9-12), self-reported peer ethnic discrimination, interracial climate at school, and perceived school ethnic composition were assessed. At the school level, objective high school ethnic composition data were collected. Peer ethnic discrimination was found to decline slightly across the high school years. Above and beyond this decline, more positive perceptions of the school interracial climate and both objective and perceived numerical ethnic majority status predicted lower levels of peer ethnic discrimination. Taken together, the results highlight the significance of both objective (e.g., ethnic composition) and subjective (e.g., interracial climate) aspects of the school ethnic context to students' high school social experiences.

Longitudinal consistency of adolescent ethnic identification across varying school ethnic contexts.

The present study examined consistency and inconsistency in adolescents' ethnic identification (i.e., self-reported ethnicity) across the 6 middle-school semesters. The sample (N = 1,589, of whom 46% were boys and 54% were girls) included African American, Asian/Pacific Islander, Caucasian/White, Latino/Latina, Mexican/Mexican American, and multiethnic students. Latent class analyses yielded 3 key patterns in ethnic identification across the middle-school years: consistent, late consistent, and inconsistent. Ethnic identification remained consistent across fall and spring of 6th, 7th, and 8th grades for only about 60% of the students. Asian/Pacific Islander students were more consistent, and multiethnic students were less consistent than students from other ethnic groups. School ethnic composition was associated with systematic shifts in ethnic identification from the beginning to the end of middle school for those students who initially identified as Latino/Latina, African American, or multiethnic but not for Mexican-origin students. In combination, the results provide insight into the consistency of ethnic identification, the role of context in adolescents' self-representation, and considerations for longitudinal studies that examine ethnic differences.

"It must be me": ethnic diversity and attributions for peer victimization in middle school.

This study examined the mediating role of self-blaming attributions on peer victimization-maladjustment relations in middle school and the moderating role of classroom ethnic diversity. Latino and African American 6th grade participants (N = 1105, 56% female) were recruited from middle schools in which they were either members of the numerical majority ethnic group, the numerical minority, or one of several ethnic groups in ethnically diverse schools. Peer nomination data were gathered in the Fall of 6th grade to determine which students had reputations as victims of harassment and self-report data on self-blame for peer harassment and the adjustment outcomes of depressive symptoms and feelings of self-worth were gathered in the Spring of 6th grade, approximately 6 months later. A mediational model in which self-blame partly explained the relation between victimization and maladjustment was supported among students from the majority ethnic group in their classroom but not among students from the minority group. The usefulness of including ethnic diversity as an important context variable in studies of peer victimization during early adolescence was discussed.

Understanding Adolescent Delinquency: The Role of Older Siblings' Delinquency and Popularity with Peers.

The present study examined delinquency concordance and the moderating effects of younger sibling perceptions of older sibling popularity in a sample of 587 adolescent sibling pairs. Using a social learning framework, and taking dyad composition into account, perceptions of popularity were hypothesized to strengthen siblings' concordance for delinquency. Older sibling delinquency significantly predicted younger sibling delinquency. Older sibling popularity was not important in predicting boys' delinquency. However, perceptions of older sibling popularity directly predicted reduced delinquency for girls with older sisters. A significant interaction effect was found for girls with older brothers. Older brother delinquency predicted girls' delinquency for girls who perceived their older brother to be relatively popular. There was no delinquency concordance for girls who perceived their older brothers to be less popular.

Marital satisfaction, recovery from work, and diurnal cortisol among men and women.

DESIGN: Multilevel modeling was used to model relationships between salivary cortisol, daily diary ratings of work experiences, and Marital Adjustment Test scores (Locke & Wallace, 1959), in a sample of 60 adults who sampled saliva 4 times per day over 3 days. RESULTS: Among women but not men, marital satisfaction was significantly associated with a stronger basal cortisol cycle, with higher morning values and a steeper decline across the day. For women but not men, marital satisfaction moderated the within-subjects association between afternoon and evening cortisol level, such that marital quality appeared to bolster women's physiological recovery from work. For both men and women, evening cortisol was lower than usual on higher-workload days, and marital satisfaction augmented this association among women. Men showed higher evening cortisol after more distressing social experiences at work, an association that was strongest among men with higher marital satisfaction. CONCLUSION: This work has implications for the study of physiological recovery from work, and also suggests a pathway by which marital satisfaction influences allostatic load and physical health.
