The Impact of Experimental Education on Adolescent Development

This article summarizes the findings of a national study of 27 varied programs and concludes that experience-based educational programs can have a significant positive impact on the social, psychological, and intellectual development of adolescents.     

Adolescent Children of Adolescent Mothers: The Impact of Family Functioning on Trajectories of Development

This study drew on four cycles of longitudinal data from the Canadian National Longitudinal Survey of Children and Youth to examine the academic and behavioural trajectories of youth between 10 and 15 years of age as a function of maternal age at childbearing. The analyses controlled for several family characteristics and examined the mediating effects of three family functioning variables (maternal depression, and nurturing and rejecting parenting behaviours). Maternal age was related to academic competency in math (standardized Math scores), externalizing disorders (Property Offences, Hyperactivity-Inattention), and internalizing disorders (Anxiety-Emotional Disorder). After accounting for family characteristics, the children of the young and older teen mothers retained their disadvantage in Math scores and Property Offences, respectively, whereas the children of older mothers lost the advantages that they had exhibited at age 10 (for Property Offences, the benefits were mediated through family functioning). These results have implications for future research and for the development of policy and programming targeting the healthy development of youth.

Growth in Adolescent Self-Regulation and Impact on Sexual Risk-Taking: A Curve-of-Factors Analysis

Adolescent self-regulation is increasingly seen as an important predictor of sexual risk-taking behaviors, but little is understood about how changes in self-regulation affect later sexual risk-taking. Family financial stress may affect the development of self-regulation and later engagement in sexual risk-taking. We examined whether family financial stress influences self-regulation in early adolescence (age 13) and growth in self-regulation throughout adolescence (from age 13–17 years). We then assessed the effects of family financial stress, baseline self-regulation, and the development of self-regulation on adolescent sexual risk-taking behaviors at age 18 years. Using a curve-of-factors model, we examined these relationships in a 6-year longitudinal study of 470 adolescents (52% female) and their parents from a large northwestern city in the United States. Results indicated that family financial stress was negatively associated with baseline self-regulation but not with growth in self-regulation throughout adolescence. Both baseline self-regulation and growth in self-regulation were predictive of decreased likelihood of engaging in sexual risk-taking. Family financial stress was not predictive of later sexual risk-taking. Intervening to support the development of self-regulation in adolescence may be especially protective against later sexual risk-taking.     

The Impact of African American Fathers on Adolescent Sexual Behavior

A common finding in past research on adolescent sexual behavior is that initiation of sexual intercourse is more frequent in households where the teen does not live with both biological parents. The present study examined this result in greater depth by examining the impact that father attitudes toward premarital sexual intercourse have on the sexual behavior of the father's adolescent. Approximately 750 inner-city African American youth between the ages of 14 and 17 were interviewed in a survey on parent–teen communication. Results showed that adolescent perceptions of paternal attitudes were predictive of teen sexual behavior independent of adolescent perceptions of maternal attitudes and that the effects of live-in status on sexual behavior were mediated by adolescent perceptions of paternal attitudes. This result was robust across gender and age of the adolescent.     

A Longitudinal Study of Self-Esteem: Implications for Adolescent Development

This study used a cluster analytic approach to identify self-esteem trajectories among adolescents over a four-year period from sixth to tenth grades (N = 1,160). Four self-esteem trajectories were identified that replicated previous research: (1) consistently high, (2) moderate and rising, (3) steadily decreasing, and (4) consistently low. Female adolescents were more likely to be in the steadily decreasing self-esteem group while male adolescents were more likely to be in the moderate and rising group. African American and white youth were equally distributed across groups. Using repeated measures analysis, we found that youth with consistently high and moderate and rising self-esteem reported developmentally healthier outcomes in Grade 10 than youth in the other two clusters. Outcomes included susceptibility to peer pressure, school grades, and alcohol use. Implications of these results for studying self-esteem and developmental change more generally are discussed.     

Adolescent Sleep Barriers: Profiles within a Diverse Sample of Urban Youth

Most adolescents face numerous obstacles to good sleep, which may undermine healthy development. In this study, we used latent class analysis and identified four categories of sleep barriers in a diverse sample of 553 urban youth (57% female). The majority profile, School/Screens Barriers, reported the most homework and extracurricular barriers, along with high screen time. The Home/Screens Barriers class (i.e., high environmental noise, light, screen use) and the High/Social Barriers class (i.e., high barriers across domains, particularly social) reported the poorest sleep quality and highest depressive/anxiety symptoms. The Minimal Barriers class—predominately male, with low depressive/anxiety symptoms—reported more sleep per night. We discuss implications of our findings for targeting interventions to address poor adolescent sleep among specific clusters of students.     

Impact of Early Adolescent Externalizing Problem Behaviors on Identity Development in Middle to Late Adolescence: A Prospective 7-Year Longitudinal Study

Adolescents at-risk for problem behaviors can have more difficulties in developing a firm sense of personal identity. Hence the purpose of this prospective longitudinal study was to scrutinize how externalizing problems in early adolescence impact identity development in middle to late adolescence. Participants were 443 (43.12 % female) Dutch adolescents. Teachers rated their externalizing problem behaviors when participants were 11 or 12 years old and their identity formation was studied during five consecutive years (from 14 to 18 years of age). The sample was divided into four groups: boys and girls with a high versus a low-risk for externalizing problem behaviors. Participants completed a self-report measure of identity commitment, in-depth exploration, and reconsideration of commitment. Multi-group Latent Growth Curve and profile stability analyses were used to evaluate identity development across adolescence. Findings indicated that high-risk boys and girls reported a less structured identity, with lower levels of commitment and higher levels of reconsideration of commitment. Since externalizing problems behaviors and lack of a coherent sense of identity might reinforce each other, early intervention for high-risk adolescents might foster positive youth development.     

Measuring Puberty and Understanding Its Impact: A Longitudinal Study of Adolescent Twins

Pubertal development is an important focus of current biopsychosocial research. The Pubertal Development Scale or PDS (Petersen, Crockett, Richards, and Boxer, J. Youth Adolesc. (1988) 17: 117–133) has become a widely used measure in school-based and longitudinal research, because it incorporates several indices of pubertal development. This study reports normative data on the PDS for two population-based birth cohorts of Finnish twin boys and girls, assessed at ages 11–12 and 14. Additionally, we report longitudinal analyses of the associations between pubertal development and substance use, suggesting that the impact of pubertal timing is more complex than previously reported; associations commonly assumed between pubertal development and substance use held only for those whose developmental level, relative to peers, remained stable across follow-up. Finally, we report twin correlations for the PDS which suggest that sibling similarity for pubertal development arises from both shared genes and shared environments and that the patterns of these influences vary between sexes and across time.     

The Impact of Pubertal Timing and Parental Control on Adolescent Problem Behaviors

This study examined the relationship among pubertal timing, parental control, and problem behaviors. There were 267 participants, whose ages ranged from 9 to 16 years. Both maternal and paternal psychological control predicted problem behaviors over and above the effects of behavioral control. For boys, early maturation and high levels of paternal psychological control, whereas for girls, on-time maturation and low levels of paternal psychological control were associated with low levels of internalizing problem behaviors. Early maturation and high levels of maternal psychological control predicted high levels of externalizing problem behaviors. The implications of these findings were discussed in terms of the detrimental effects of psychological control on adolescent wellbeing, the role that pubertal timing may or may not play during this period, and finally the need to separately examine fathers’ parenting and mothers’ parenting while investigating the impact of parental control on adolescent problem behaviors.

The Impact of Birth Order on Intergenerational Transmission of Attitudes from Parents to Adolescent Sons: The Israeli Case

This study deals with birth order and its impact on intergenerational transmission of parental attitudes to adolescent sons in Israeli society. The sample included 294 participants (including 98 mothers, 98 fathers, and 98 sons). The attitudes chosen were key issues of concern in Israeli society: gender role attitudes, ethnic stereotypes, and attitudes toward immigrants from the former USSR (disposition toward contact and empathy toward immigrants). The findings indicate that birth order impacts on intergenerational transmission of attitudes from parents to adolescents, although the nature of this impact is different for mothers and fathers. The correlation between fathers' attitudes and those of their sons were strongest for the firstborn, and decreased according to birth order. The reverse trend was found for mothers. In addition, firstborns expressed greater willingness to approach immigrants than did middle and younger children. Regarding gender role attitudes and ethnic stereotypes, no impact was found for birth order. Compared with other family members, mothers expressed the most liberal gender role attitudes, and children expressed the least stereotyped attitudes toward ethnic groups, especially compared with their fathers.     

The Effects of Adolescent Activities on Delinquency: A Differential Involvement Approach

T. Hirschi’s (1969, Causes of Delinquency. University of California Press, Berkeley, CA) control theory proposes that involvement, as an element of the social bond, should reduce delinquency. But, research studies have found that the effect of involvement is rather weak. This study reformulates Hirschi’s involvement hypothesis by posing involvement as a social setting variable and a differential factor. Certain activities provide a social setting favorable to the development of the social bond and the reduction in delinquent association. The reformulated hypothesis is examined based on a sample of Grade 7–12 students in a Western Canadian city. The results reveal that school- and family-related activities strengthen the social bond and reduce delinquent association and delinquency. In contrast, other conventional activities such as spending time with friends and dating have the opposite effects. In addition, the indirect effect of differential involvement on delinquency through the social bond and delinquent association is stronger than its direct effect. Thus, the undesirable effects of the less-positive activities on delinquency may be buffered or reduced by strengthening the social bond and reducing delinquent association.Siu Kwong Wong is an Associate Professor of Sociology at Brandon University.

A Longitudinal Investigation of Cognitive Self-schemas across Adolescent Development

Research in developmental psychology highlights youth’s self-schemas as one possible pathway to improve adolescents’ functioning and promote positive developmental outcomes. Despite this, the trajectory of positive and negative self-schemas is relatively understudied. This study addresses this limitation by empirically examining the trajectory of self-schemas in a community sample of 623 youth (M?=?13.04 years; 54% female; 49% African American, 4% Biracial, 47% European American) who were followed over a seven-year period. Caregivers completed measures of parenting practices, maternal rumination and negative inferential style, and adolescents completed a computerized behavioral task assessing self-schemas (i.e., mental frameworks that guide attention, interpretation, and memory of one’s experiences). Multilevel growth curve modeling results demonstrated a quadratic slope for negative self-schemas and no mean-level change for positive self-schemas. These trajectories did not vary by gender or racial group. However, parenting factors differentially influenced the trajectories. Specifically, higher levels of parental involvement at baseline, or an active interest and engagement in a child’s experiences and activities, related to lower levels of negative self-schemas during adolescence. Additionally, higher levels of parental rumination and parental negative control at baseline related to lower levels of youth positive self-schemas at baseline. These findings contribute to models of youth cognitive development.

     

Adolescent Participation in Structured and Unstructured Activities: A Person-Oriented Analysis

The current study used a person-oriented approach to examine the participation of adolescents in both constructive, organized activities as well as relaxed leisure activities. The goal of this research was to identify different profiles of involvement in activities and the relations to psychosocial indicators for these differing groups. Activity profiles were created using cluster analytic techniques for 918 adolescents' responses in 11 activity domains. The groups were found to be both statistically and substantively unique and consistent with findings from previous research. Further, the groups showed meaningful and consistent differences across a range of psychosocial indicators, including academic performance, problem behavior, and mental health. Results indicated that adolescents' activity involvement was related to their psychological and behavioral functioning and that the profiles of participation across activity settings provide a more holistic view of teens' choices than do single variable models.     

School-Based Extracurricular Activity Involvement and Adolescent Self-Esteem: A Growth-Curve Analysis

Research on adolescent self-esteem indicates that adolescence is a time in which individuals experience important changes in their physical, cognitive, and social identities. Prior research suggests that there is a positive relationship between an adolescent??s participation in structured extracurricular activities and well-being in a variety of domains, and some research indicates that these relationships may be dependent on the type of activities in which adolescents participate. Building on previous research, a growth-curve analysis was utilized to examine self-esteem trajectories from adolescence (age 14) to young adulthood (age 26). Using 3 waves of data from National Longitudinal Study of Adolescent Health (n = 5,399; 47.8% male), the analysis estimated a hierarchical growth-curve model emphasizing the effects of age and type of school-based extracurricular activity portfolio, including sports and school clubs, on self-esteem. The results indicated that age had a linear relationship with self-esteem over time. Changes in both the initial level of self-esteem and the growth of self-esteem over time were significantly influenced by the type of extracurricular activity portfolio. The findings were consistent across race and sex. The results support the utility of examining the longitudinal impact of portfolio type on well-being outcomes.     

Effects of Deviant Peer Association on Adolescent Alcohol Consumption: A Growth Mixture Modeling Analysis

This study examined concurrent and lagged effects of deviant peer association on levels of alcohol use for distinctive trajectories of drinking from ages 14–18 years, while controlling for age, paternal education, community size, and conduct problems. Longitudinal data were available from a secondary data archive of male and female German adolescents (N = 1,619). Conditional latent growth mixture modeling analysis indicated consistent concurrent effects of deviant peer association (specified as time-varying covariate) on alcohol use for the regular users group, but not any of the other drinking trajectory groups. Very few lagged effects of deviant peers association on alcohol use were found, and thus the social influence hypothesis received little empirical support. Overall, findings suggest the need to consider heterogeneity in the study of peer characteristics and alcohol use for both male and female adolescents.

The Skinny on Body Dissatisfaction: A Longitudinal Study of Adolescent Girls and Boys

The present study tested whether theoretically derived risk factors predicted increases in body dissatisfaction and whether gender moderated these relations with data from a longitudinal study of 428 adolescent girls and boys because few prospective studies have examined these aims, despite evidence that body dissatisfaction increases risk for various psychiatric disturbances. Body dissatisfaction showed significant increases for girls and significant decreases for boys during early adolescence. For both genders, parental support deficits, negative affectivity, and self-reported dietary restraint showed significant relations to future increases in body dissatisfaction. Ideal body internalization and body mass index did not demonstrate significant relations to future increases in body dissatisfaction; peer support deficits showed a marginal relation to this outcome. Gender did not moderate these relations, despite adequate power to detect interactive effects.
