Late Adolescence (late + adolescence)
Selected AbstractsStable Postdivorce Family Structures During Late Adolescence and Socioeconomic Consequences in AdulthoodJOURNAL OF MARRIAGE AND FAMILY, Issue 1 2008Yongmin Sun Using four waves of panel data from 6,954 American young adults in the National Education Longitudinal Study, we compare the long-term socioeconomic consequences of growing up in two types of divorced families. Our findings show that the negative socioeconomic consequences of growing up in unstable postdivorce families are at least twice as large as those of staying in a stabilized postdivorce family environment through late adolescence. The study also finds that variations in parental resources during late adolescence partially explain the divorce effects on most attainment indicators. Further, parental divorce appears to affect the socioeconomic attainment of male and female offspring alike. Overall, the study underlines the importance of including postdivorce family dynamics in studying the effect of parental divorce. [source] Racial and Ethnic Differences in Experiencing Parents' Marital Disruption During Late AdolescenceJOURNAL OF MARRIAGE AND FAMILY, Issue 3 2007Yongmin Sun Using panel data from 9,252 adolescents in the National Education Longitudinal Study, this study finds that among children who experience parents' marital disruption during late adolescence, European, Asian, and African American adolescents exhibit wider and greater maladjustment both before and after the disruption than their Hispanic American counterparts. This finding lends general support to the hypothesis of prevalence of disadvantages, although it is less consistent with the hypothesis of prevalence of divorce. Moreover, whereas Asian American adolescents in predisrupted families are more vulnerable to a shortage of family social resources, their African American peers are affected more by a shortage of financial/human resources. Finally, postdisruption effects on non-Hispanic American adolescents are either completely or partially attributable to predisruption factors. [source] A Self-Regulatory Model of Behavioral Disinhibition in Late Adolescence: Integrating Personality Traits, Externalizing Psychopathology, and Cognitive CapacityJOURNAL OF PERSONALITY, Issue 2 2010Tim Bogg ABSTRACT Two samples with heterogeneous prevalence of externalizing psychopathology were used to investigate the structure of self-regulatory models of behavioral disinhibition and cognitive capacity. Consistent with expectations, structural equation modeling in the first sample (N=541) showed a hierarchical model with 3 lower order factors of impulsive sensation seeking, antisociality/unconventionality, and lifetime externalizing problem counts, with a behavioral disinhibition superfactor best accounted for the pattern of covariation among 6 disinhibited personality trait indicators and 4 externalizing problem indicators. The structure was replicated in a second sample (N=463) and showed that the behavioral disinhibition superfactor, and not the lower order impulsive sensation seeking, antisociality/unconventionality, and externalizing problem factors, was associated with lower IQ, reduced short-term memory capacity, and reduced working memory capacity. The results provide a systemic and meaningful integration of major self-regulatory influences during a developmentally important stage of life. [source] Stability and Change in Personality Traits From Late Adolescence to Early Adulthood: A Longitudinal Twin StudyJOURNAL OF PERSONALITY, Issue 2 2008Daniel M. Blonigen ABSTRACT We conducted a longitudinal-biometric study examining stability and change in personality from ages 17 to 24 in a community sample of male and female twins. Using Tellegen's (in press) Multidimensional Personality Questionnaire (MPQ), facets of Negative Emotionality (NEM) declined substantially at the mean and individual levels, whereas facets of Constraint (CON) increased over time. Furthermore, individuals in late adolescence who were lowest on NEM and highest on CON remained the most stable over time, whereas those exhibiting the inverse profile (higher NEM, lower CON) changed the most in a direction towards growth and maturity. Analyses of gender differences yielded greater mean-level increases over time for women as compared to men on facets of CON and greater mean-level increases for men than women on facets of Agentic Positive Emotionality (PEM). Biometric analyses revealed rank-order stability in personality to be largely genetic, with rank-order change mediated by both the nonshared environment (and error) as well as genes. Findings correspond with prior evidence of a normative trend toward growth and maturity in personality during emerging adulthood. [source] Personality Development From Late Adolescence to Young Adulthood: Differential Stability, Normative Maturity, and Evidence for the Maturity-Stability HypothesisJOURNAL OF PERSONALITY, Issue 2 2007M. Brent Donnellan ABSTRACT This investigation examined personality development during the transition from adolescence to adulthood using the brief form of the Multidimensional Personality Questionnaire (Patrick, Curtin, & Tellegen, 2002). Parent and self-reports of personality were obtained in 1994 (average age=17.60 years), and self-reports were obtained in 2003 (average age=27.24 years). There was evidence of both differential stability and normative changes in the direction of increased functional maturity during this transition. Moreover, adolescents with more mature personalities in 1994 tended to show fewer personality changes from 1994 to 2003. These maturity-stability effects held when parent reports were used to assess personality. All told, there was evidence of both stability and change in personality during the transition to adulthood. [source] Drinking Alcohol before Age 13 and Negative Outcomes in Late AdolescenceALCOHOLISM, Issue 11 2009Neta Peleg-Oren Background:, Research has shown that adolescents who begin drinking at an early stage in life are at greater risk of developing alcohol dependency, as well as a variety of negative outcomes, for instance, delinquent behavior. Most of these studies have focused on those who begin drinking in middle adolescence, but little attention has been paid to youth who initiate drinking under the age of 13. Twenty percent of adolescents have begun using alcohol by the age of 13. The purpose of the study is to examine whether initiating alcohol use before the age of 13 exacerbates negative outcomes in late adolescence. Methods:, Data for the study were derived from 2 school-based statewide surveys conducted in Florida: the 2005 YRBS and the 2006 FYSAS. The sample included 12,352 11th and 12th grade students divided into 3 groups: students who initiated alcohol use under the age of 13, students who initiated alcohol use at age 13 or later, and students who never used alcohol. Results:, Results showed that after adjusting for gender, ethnicity/race, and grade, adolescents who initiated alcohol use before age 13 were more likely to report problems with school performance and display delinquent behaviors (carrying a gun, carrying a weapon to school, and recent marijuana use). Conclusion:, Although no temporal relationships can be determined between drinking alcohol before age 13 and delinquent behavior outcomes, the results suggested that adolescents under the age of 13 need to be included in national epidemiological surveys on alcohol use and more efforts need to be directed toward the implementation of prevention programs early in elementary and middle schools. [source] Aggressive behaviour and social problem-solving strategies: a review of the findings of a seven-year follow-up from childhood to late adolescenceCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 4 2001Liisa Keltikangas-Järvinen PhD Professor Objectives In a seven-year follow-up study, the author and colleagues examined the development of social skills from childhood to late adolescence, with a particular focus on aggressive behaviour. This paper presents a review of the most important findings of the project. Results and conclusions Social strategies explained aggressive behaviour, and changes of strategies predicted changes of behaviour. Aggressive behaviour was, however, very stable, and spontaneous change from an aggressive child to a sociable adolescent was not observed. This emphasizes an importance of early prevention of aggression. Disagreement between the children's and their parents' problem-solving strategies was apparent, suggesting that interventions to reduce a child's aggression should be augmented by educating the parents about their children's behaviour. The role of peers was important because the child's concept of his or her strategies was dependent on his or her social acceptance, and this should be taken into account in interventions. Finally, as approval or disapproval of aggression is related to behaviour, moral cognitions should be included in the interventions. Copyright © 2001 Whurr Publishers Ltd. [source] VIOLENCE AMONG ADOLESCENTS LIVING IN PUBLIC HOUSING: A TWO-SITE ANALYSIS,CRIMINOLOGY AND PUBLIC POLICY, Issue 1 2003TIMOTHY O. IRELAND Research Summary: Current knowledge about violence among public housing residents is extremely limited. Much of what we know about violence in and around public housing is derived from analysis of Uniform Crime Report (UCR) data or victimization surveys of public housing residents. The results of these studies suggest that fear of crime among public housing residents is high and that violent offense rates may be higher in areas that contain public housing compared with similar areas without public housing. Yet, "[r]ecorded crime rates (and victimization rates) are an index not of the rate of participation in crime by residents of an area, but of the rate of crime (or victimization) that occurs in an area whether committed by residents or non-residents" (Weatherburn et al., 1999:259). Therefore, neither UCR nor victimization data measurement strategies address whether crime in and around public housing emanates from those who reside in public housing. Additionally, much of this research focuses on atypical public housing,large developments with high-rise buildings located in major metropolitan areas. To complement the existing literature, we compare rates of self-reported crime and violence among adolescents who reside in public housing in Rochester, N.Y., and Pittsburgh, Pa., with adolescents from the same cities who do not live in public housing. In Rochester, property crime and violence participation rates during adolescence and early adulthood among those in public housing are statistically equivalent to participation rates among those not in public housing. In Pittsburgh, living in public housing during late adolescence and early adulthood, particularly in large housing developments,increases the risk for violent offending, but not for property offending. The current study relies on a relatively small number of subjects in public housing at any single point in time and is based on cross-sectional analyses. Even so, there are several important policy implications that can be derived from this study, given that it moves down a path heretofore largely unexplored. Policy Implications: If replicated, our findings indicate that not all public housing is inhabited disproportionately by those involved in crime; that to develop appropriate responses, it is essential to discover if the perpetrators of violence are residents or trespassers; that policy should target reducing violence specifically and not crime in general; that a modification to housing allocation policies that limits, to the extent possible, placing families with children in late adolescence into large developments might reduce violence perpetrated by residents; that limited resources directed at reducing violence among residents should be targeted at those developments or buildings that actually have high rates of participation in violence among the residents; and that best practices may be derived from developments where violence is not a problem. [source] Dental trauma that require fixation in a children's hospitalDENTAL TRAUMATOLOGY, Issue 1 2008Timothy Bruns Complex injuries to permanent teeth and their periodontium require immediate repositioning and stabilization. Many of these emergencies are treated by pediatric dental residents at the Women and Children's Hospital of Buffalo, Buffalo, New York. The purpose of this study was to characterize these complex injuries of permanent teeth that require emergency treatment in a Children's Hospital. All of the cases of dental trauma which had involved permanent teeth and which had been treated with a splint in 2001 and 2002 were reviewed. There were 79 patients that were between 5 and 19 years of age with twice as many males (54) as females (25). The number of males increased from childhood (5,10 years) to early adolescence (11,15 years) and then decreased rapidly in late adolescence (16,19 years), whereas the number of females decreased steadily with age. Most of the incidents occurred during the summer months (72%), particularly in June and July (42%), and Fridays and Saturdays were the busiest days of the week. Most of the injuries were caused by organized and recreational sporting activities (39%) and accidental falls (33%), followed by interpersonal violence (15%) and a few motor vehicle accidents (7%). The 173 permanent tooth injuries were mostly luxations (62%) or avulsions (20%), with only a few fractures of the alveolar bone (5%) or tooth root (1%). Most of the displacements were lateral luxations (40%) or extrusions (18%) with only a few intrusions (3%). These injuries most commonly afflicted the maxillary central incisors (54%), followed by the maxillary laterals (18%) and mandibular centrals (17%). The emergency treatment that was provided at the Children's Hospital included replantation and repositioning, and the placement of a semi-rigid or flexible splint. [source] Adolescent smoking and depression: evidence for self-medication and peer smoking mediationADDICTION, Issue 10 2009Janet Audrain-McGovern ABSTRACT Aims The nature of the relationship between adolescent smoking and depression is unclear and the mechanisms that account for the comorbidity have received little investigation. The present study sought to clarify the temporal precedence for smoking and depression and to determine whether these variables are linked indirectly through peer smoking. Participants The sample was composed of 1093 adolescents participating in a longitudinal study of the behavioral predictors of smoking adoption. Design and measurements In this prospective cohort study, smoking, depression, peer smoking and other covariates were measured annually from mid-adolescence (9th grade; age 14) to late adolescence (12th grade, age 18). Findings Parallel processes latent growth curve models supported a bidirectional relationship between adolescent smoking and depression, where higher depression symptoms in mid-adolescence (age 14) predicted adolescent smoking progression from mid- to late adolescence (ages 14,18). A significant indirect effect indicated that higher depression symptoms across time predicted an increase in the number of smoking peers, which in turn predicted smoking progression from mid-adolescence to late adolescence. In addition, smoking progression predicted a deceleration of depression symptoms from mid- to late adolescence. A significant indirect effect indicated that greater smoking at baseline predicted a deceleration in the number of smoking peers across time, which predicted a deceleration in depression symptoms from mid-adolescence to late adolescence. Conclusions The current study provides the first evidence of bidirectional self-medication processes in the relationship between adolescent smoking and depression and highlights peer smoking as one explanation for the comorbidity. [source] Does sports participation during adolescence prevent later alcohol, tobacco and cannabis use?ADDICTION, Issue 1 2009Tove Wichstrøm ABSTRACT Aims To study whether participation in organized sports during adolescence predicts increased smoking of tobacco, alcohol intoxication and cannabis use from late adolescence to adulthood when controlling for potential confounders. Moreover, to study whether such increased drug use varies according to type of sport (team versus individual), main skills needed (endurance, strength or technical) and level of competition. Design, setting and participants Survey of national sample of Norwegian high school students (aged 13,19 years) in 1992 (T1) followed-up in 1994 (T2), 1999 (T3) and 2006 (T4) (n = 3251). Measurements Outcome measures included smoking of tobacco and 12-month prevalences of alcohol intoxication and cannabis use, respectively. Confounders included pubertal timing, friends' drug use, perceived social acceptance, grades and parental socio-economic status. Findings Latent growth curve analyses showed that initial level of participation in organized sports predicted growth in alcohol intoxication. Those involved initially in team sports had greater growth in alcohol intoxication, but lower growth in tobacco use and cannabis use, during the adolescent and early adult years compared to those involved in technical or strength sports. Practising endurance sports, as opposed to technical or strength sports, predicted reduced growth in alcohol intoxication and tobacco use. Conclusions Sports participation in adolescence, and participation in team sports in particular, may increase the growth in alcohol intoxication during late adolescent and early adult years, whereas participation in team sports and endurance sports may reduce later increase in tobacco and cannabis use. [source] Cannabis use and later life outcomesADDICTION, Issue 6 2008David M. Fergusson ABSTRACT Aim To examine the associations between the extent of cannabis use during adolescence and young adulthood and later education, economic, employment, relationship satisfaction and life satisfaction outcomes. Design A longitudinal study of a New Zealand birth cohort studied to age 25 years. Measurements Measures of: cannabis use at ages 14,25; university degree attainment to age 25; income at age 25; welfare dependence during the period 21,25 years; unemployment 21,25 years; relationship quality; life satisfaction. Also, measures of childhood socio-economic disadvantage, family adversity, childhood and early adolescent behavioural adjustment and cognitive ability and adolescent and young adult mental health and substance use. Findings There were statistically significant bivariate associations between increasing levels of cannabis use at ages 14,21 and: lower levels of degree attainment by age 25 (P < 0.0001); lower income at age 25 (P < 0.01); higher levels of welfare dependence (P < 0.0001); higher unemployment (P < 0.0001); lower levels of relationship satisfaction (P < 0.001); and lower levels of life satisfaction (P < 0.0001). These associations were adjusted for a range of potentially confounding factors including: family socio-economic background; family functioning; exposure to child abuse; childhood and adolescent adjustment; early adolescent academic achievement; and comorbid mental disorders and substance use. After adjustment, the associations between increasing cannabis use and all outcome measures remained statistically significant (P < 0.05). Conclusions The results of the present study suggest that increasing cannabis use in late adolescence and early adulthood is associated with a range of adverse outcomes in later life. High levels of cannabis use are related to poorer educational outcomes, lower income, greater welfare dependence and unemployment and lower relationship and life satisfaction. The findings add to a growing body of knowledge regarding the adverse consequences of heavy cannabis use. [source] Drinking patterns in mid-adolescence and psychosocial outcomes in late adolescence and early adulthoodADDICTION, Issue 12 2004J. Elisabeth Wells ABSTRACT Aims To describe the pattern of drinking at age 16 and to relate this to outcomes at 16,21 years and 21,25 years across a number of psychosocial domains. Design A prospective birth cohort study with annual follow-up until age 16 then at 18, 21 and 25 years. Setting Christchurch, New Zealand. Participants Of 1265 subjects, 953 were interviewed at age 16. Measurements Multiple measures of family background were collected from birth to 16 years. Alcohol consumption was measured in terms of frequency, usual or last quantity drunk and most drunk per occasion. Problems were also recorded. Questions about psychiatric symptoms enabled Diagnostic and Statistical Manual (DSM) criteria to be applied. Detailed reports on educational outcomes, employment, sexual behaviours and offending were collected. Findings Four latent classes were required to describe drinking at age 16, but these appeared to lie along a single dimension which strongly predicted outcomes at ages 16,21 and 21,25 across all domains (alcohol-related, substance dependence, mental health, education, sexual relationships and offending). After controlling for background and correlates only a small number of outcomes were still related consistently to drinking at age 16 over both periods: most alcohol-related outcomes, the number of sexual partners and the extent of violent offending. Conclusions Drinking at age 16 is a clear indicator of future life-course over most domains in late adolescence and early adulthood. Many of these associations are due to other covariates. Outcomes specific to drinking at age 16 are alcohol outcomes, number of sexual partners and violence. [source] Twenty-year follow-up of bulimia nervosa and related eating disorders not otherwise specifiedINTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 6 2010Pamela K. Keel PhD Abstract Objective This study reports 20-year outcome of bulimia nervosa (BN) and related eating disorders not otherwise specified (EDNOS) and point prevalence of BN and EDNOS for a cohort of women and men in late adolescence (mean age = 20 ± 2 years), adulthood (30 ± 2 years), and mid-life (40 ± 2 years). Method N = 654 women and men, 73% of those assessed in 1982, completed 20-year follow-up in a two-stage design including questionnaires and structured clinical interviews. Results Approximately 75% of women with BN were in remission at 20-year follow-up, and outcome did not differ significantly between BN and EDNOS. Eating disorder point prevalence declined in women but not men from late adolescence to mid-life. Discussion Despite patterns of improvement in women, 4.5% reported a clinically significant eating disorder at mid-life, suggesting the need for more research on potential risk factors in this age group, such as pressures for women to maintain a youthful appearance. © 2009 by Wiley Periodicals, Inc.

May MS Objective: This work describes the developmental course of adolescents' weight concerns and examines links with changes in parent,adolescent relationships for girls and boys. Method: Adolescents and parents in 191 families participated in 3 annual home interviews; adolescents rated their weight concerns and their intimacy and conflict with parents. Parental knowledge was measured based on the match between adolescents' and parents' reports of youth's experiences each day during 7 evening telephone calls. Results: Girls' weight concerns increased from age 11 to 16 and then declined, whereas boys' concerns declined beginning at age 11. Increases in girls' weight concerns were linked to increases in conflict with mothers and fathers and decreases in maternal intimacy and knowledge. At a trend level, declines in boys' weight concerns were associated with declines in father conflict. Conclusion: Mothers and fathers may have unique influences on adolescent weight concerns. Intervention programming should target parent,adolescent relationships. © 2006 by Wiley Periodicals, Inc.

DESIGN AND METHODS.,Investigators conducted semistructured qualitative interviews with 15 college students with ADHD. Follow-up interviews confirmed and validated information obtained during initial interviews. RESULTS.,Qualitative data analysis resulted in three global categories related to the use of prescription stimulant medication from childhood to late adolescence: (a) the early years, (b) "the trade-off," and (c) stimulant medications in college. PRACTICE IMPLICATIONS.,Increased education about prescription stimulant medications and closer management is needed to reduce side effects and minimize the risks of misuse. [source] A Sex Difference by Item Difficulty Interaction in Multiple-Choice Mathematics Items Administered to National Probability SamplesJOURNAL OF EDUCATIONAL MEASUREMENT, Issue 1 2001John Bielinski A 1998 study by Bielinski and Davison reported a sex difference by item difficulty interaction in which easy items tended to be easier for females than males, and hard items tended to be harder for females than males. To extend their research to nationally representative samples of students, this study used math achievement data from the 1992 NAEP, the TIMSS, and the NELS:88. The data included students in grades 4, 8, 10, and 12. The interaction was assessed by correlating the item difficulty difference (bmale, bfemale) with item difficulty computed on the combined male/female sample. Using only the multiple-choice mathematics items, the predicted negative correlation was found for all eight populations and was significant in five. An argument is made that this phenomenon may help explain the greater variability in math achievement among males as compared to females and the emergence of higher performance of males in late adolescence.

[source] Long-Term Effects of Minimum Drinking Age Laws on Past-Year Alcohol and Drug Use DisordersALCOHOLISM, Issue 12 2009Karen E. Norberg Background:, Many studies have found that earlier drinking initiation predicts higher risk of later alcohol and substance use problems, but the causal relationship between age of initiation and later risk of substance use disorder remains unknown. Method:, We use a "natural experiment" study design to compare the 12-month prevalence of Diagnostic and Statistical Manual, Fourth Edition, alcohol and substance use disorders among adult subjects exposed to different minimum legal drinking age laws minimum legal drinking age in the 1970s and 1980s. The sample pools 33,869 respondents born in the United States 1948 to 1970, drawn from 2 nationally representative cross-sectional surveys: the 1991 National Longitudinal Alcohol Epidemiological Survey (NLAES) and the 2001 National Epidemiological Study of Alcohol and Related Conditions. Analyses control for state and birth year fixed effects, age at assessment, alcohol taxes, and other demographic and social background factors. Results:, Adults who had been legally allowed to purchase alcohol before age 21 were more likely to meet criteria for an alcohol use disorder [odds ratio (OR) 1.31, 95% confidence intervals (95% CI) 1.15 to 1.46, p < 0.0001] or another drug use disorder (OR 1.70, 95% CI 1.19 to 2.44, p = 0.003) within the past-year, even among subjects in their 40s and 50s. There were no significant differences in effect estimates by respondent gender, black or Hispanic ethnicity, age, birth cohort, or self-reported age of initiation of regular drinking; furthermore, the effect estimates were little changed by inclusion of age of initiation as a potential mediating variable in the multiple regression models. Conclusion:, Exposure to a lower minimum legal purchase age was associated with a significantly higher risk of a past-year alcohol or other substance use disorder, even among respondents in their 40s or 50s. However, this association does not seem to be explained by age of initiation of drinking, per se. Instead, it seems plausible that frequency or intensity of drinking in late adolescence may have long-term effects on adult substance use patterns. [source] Drinking Alcohol before Age 13 and Negative Outcomes in Late AdolescenceALCOHOLISM, Issue 11 2009Neta Peleg-Oren Background:, Research has shown that adolescents who begin drinking at an early stage in life are at greater risk of developing alcohol dependency, as well as a variety of negative outcomes, for instance, delinquent behavior. Most of these studies have focused on those who begin drinking in middle adolescence, but little attention has been paid to youth who initiate drinking under the age of 13.

[source] The Role of Socioregional Factors in Moderating Genetic Influences on Early Adolescent Behavior Problems and Alcohol UseALCOHOLISM, Issue 10 2009Danielle M. Dick Background:, Twin and family studies have demonstrated that adolescent alcohol use and behavior problems are influenced by a combination of genetic and environmental factors. More recently, studies have begun to investigate how genetic and environmental influences may interact, with efforts underway to identify specific environmental variables that moderate the expression of genetic predispositions. Previously, we have reported that community-level factors, including urban/rural residency, migration rates, and prevalence of young adults, moderate the importance of genetic effects on alcohol use in late adolescence (ages 16 to 18). Here, we extend these findings to test for moderating effects of these socioregional factors on alcohol use and behavior problems assessed in a younger sample of adolescent Finnish twins. Methods:, Using data from the population-based Finnish twin study, FinnTwin12, biometric twin models were fit to data on >1,400 twin pairs to examine the significance of each of the socioregional moderating variables on alcohol use measured at age 14, and behavior problems, measured at age 12. Results:, We find no evidence of a moderating role of these socioregional variables on alcohol use; however, there was significant moderation of genetic influences on behavior problems, with effects limited to girls. Genetic influences assumed greater importance in urban settings, communities with greater migration, and communities with a higher percentage of slightly older adolescents. Conclusions:, The moderation effects observed on behavior problems in early adolescence paralleled the effects found on alcohol use late in adolescence in an independent sample, providing further support for the idea that behavior problems may represent an earlier manifestation of the predisposition to subsequent alcohol problems. Our findings also support the growing body of evidence suggesting that females may be more susceptible to a variety of environmental influences than males. [source] Age Changes in Prosocial Responding and Moral Reasoning in Adolescence and Early AdulthoodJOURNAL OF RESEARCH ON ADOLESCENCE, Issue 3 2005Nancy Eisenberg Age changes' measures of prosocial responding and reasoning were examined. Participants' reports of helping, empathy-related responding, and prosocial moral reasoning were obtained in adolescence (from age 15,16 years) and into adulthood (to age 25,26 years). Perspective taking and approval/interpersonal oriented/stereotypic prosocial moral reasoning increased from adolescence into adulthood, whereas personal distress declined. Helping declined and then increased (a cubic trend). Prosocial moral judgment composite scores (and self-reflective empathic reasoning) generally increased from late adolescence into the early 20s (age 17,18 to 21,22) but either leveled off or declined slightly thereafter (i.e., showed linear and cubic trends); rudimentary needs-oriented reasoning showed the reverse pattern of change. The increase in self-reflective empathic moral reasoning was for females only. Thus, perspective taking and some aspects of prosocial moral reasoning,capacities with a strong sociocognitive basis,showed the clearest increases with age, whereas simple prosocial proclivities (i.e., helping, sympathy) did not increase with age.

The disorder usually affects children, although cases have been reported with symptom onset in late adolescence or adulthood. Myoclonus is common in Rasmussen patients, usually occurring as part of epilepsia partialis continua (EPC); however, other hyperkinetic movements are rare. This report documents a 19-year-old woman with Rasmussen's encephalitis whose clinical presentation was dominated by foot dystonia, arm athetosis, and EPC. Intravenous immunoglobulin improved both hyperkinetic movements and EPC, but benefit was transient.

Pediatr Allergy Immunol 2010: 21: 806,813. © 2010 John Wiley & Sons A/S While the prevalence of and risk factors for asthma in childhood have been studied extensively, the data for late adolescence are more sparse. The aim of this study was to provide up-to-date information on the prevalence of and risk factors for asthma in the transitional period between childhood and adulthood. A secondary aim was to analyze whether the increase in asthma prevalence has levelled off. A large-scale, detailed postal questionnaire focusing on asthma and respiratory symptoms, as well as possible risk factors, was mailed to 30 000 randomly selected subjects aged 16,75 in Gothenburg and the surrounding western Sweden region. The present analyses are based on the responses from 1261 subjects aged 16,20 (560 men and 701 women). The prevalence of physician-diagnosed asthma was 9.5%, while 9.6% reported the use of asthma medicine. In the multivariate analysis, the strongest risk factors for physician-diagnosed asthma and other asthma variables were heredity for asthma and heredity for allergy, particularly if they occurred together. Growing up on a farm significantly reduced the prevalence of physician-diagnosed asthma and the likelihood of using asthma medication, OR 0.1 (95% CI 0.02,0.95). Smoking increased the risk of recurrent wheeze, long-standing cough, and sputum production. In conclusion, the prevalence of physician-diagnosed asthma and the use of asthma medication in the 16- to 20-yr age group support the notion that the increase in asthma prevalence seen between the 1950s and the 1990s has now levelled off. In line with the hygiene hypothesis, a farm childhood significantly reduced the likelihood of asthma. The adverse effects of smoking could already be seen at this young age.

[source] Earlier Violent Television Exposure and Later Drug DependenceTHE AMERICAN JOURNAL ON ADDICTIONS, Issue 4 2008David W. Brook MD This research examined the longitudinal pathways from earlier violent television exposure to later drug dependence. African American and Puerto Rican adolescents were interviewed during three points in time (n = 463). Exposure to violent television programs in late adolescence predicted exposure to violent television programs in young adulthood, which in turn was related to tobacco/marijuana use, nicotine dependence, and later drug dependence. Some policy and clinical implications suggest regulating the times when violent television programs are broadcast, creating developmentally targeted prevention/treatment programs, and recognizing that watching violent television programs may serve as a cue regarding increased susceptibility to nicotine and drug dependence. [source] Loneliness in adolescence: gene × environment interactions involving the serotonin transporter geneTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 7 2010Eeske Van Roekel Background:, Loneliness is assumed to peak in early adolescence and to decrease throughout middle and late adolescence, but longitudinal confirmation of this tendency is lacking. Behavioral genetic studies with twin designs have found a significant genetic component for loneliness in children and adults, but no molecular genetic studies have been conducted to reveal the functional polymorphisms involved. Methods:, Associations among the serotonin transporter gene (5-HTTLPR), sex, parental support, and loneliness were examined in a longitudinal study spanning five annual waves (N = 306). Results:, Using latent growth curve modeling (LGCM), loneliness was found to be highest in early adolescence and slowly declined throughout adolescence. The 5-HTTLPR genotype was related to the development of loneliness, in that short allele carriers remained stable in loneliness over time, whereas adolescents with the long-long genotype decreased in loneliness. Interactions were found between maternal support and 5-HTTLPR genotype, showing that adolescents who perceived little support from their mothers and carried a short allele were at increased risk for developing loneliness. Conclusions:, Our study is the first to chart adolescent loneliness longitudinally and to examine the genetic underpinnings of loneliness. Our results contribute to a further understanding of the environmental and genetic basis of loneliness. Replication of our results is needed in both population-based and clinical samples.
