226 to 250 of 838Beyond stereotypes of adolescent risk taking: Placing the adolescent brain in developmental context.
Recent neuroscience models of adolescent brain development attribute the morbidity and mortality of this period to structural and functional imbalances between more fully developed limbic regions that subserve reward and emotion as opposed to those that enable cognitive control. We challenge this interpretation of adolescent development by distinguishing risk-taking that peaks during adolescence (sensation seeking and impulsive action) from risk taking that declines monotonically from childhood to adulthood (impulsive choice and other decisions under known risk). Sensation seeking is primarily motivated by exploration of the environment under ambiguous risk contexts, while impulsive action, which is likely to be maladaptive, is more characteristic of a subset of youth with weak control over limbic motivation. Risk taking that declines monotonically from childhood to adulthood occurs prim…

Nutrition in adolescents: physiology, metabolism, and nutritional needs.
Adolescence is the period of development that begins at puberty and ends in early adulthood. Most commonly, adolescence is divided into three developmental periods: early adolescence (10-14 years of age), late adolescence (15-19 years of age), and young adulthood (20-24 years of age). Adolescence is marked by physical and sexual maturation, social and economic independence, development of identity, acquisition of skills needed to carry out adult relationships and roles, and the capacity for abstract reasoning. Adolescence is characterized by a rapid pace of growth that is second only to that of infancy. Nutrition and the adolescent transition are closely intertwined, since eating patterns and behaviors are influenced by many factors, including peer influences, parental modeling, food availability, food preferences, cost, convenience, personal and cultural beliefs, mass media, and body im…

Sexual Media and Childhood Well-being and Health.
Sexual content is highly prevalent in traditional media, and portrayals rarely depict the responsibilities and risks (eg, condom use, pregnancy) associated with sexual activity. Exposure to such content is linked with shifts in attitudes about sex and gender, earlier progression to sexual activity, pregnancy, and sexually transmitted infection among adolescents. However, little information is available about moderators and mediators of these effects. We also know little about digital media, their sex-related content, and their potential influence on youth. Data from a few studies of older youth indicate that sexual displays on social media sites are related to problematic beliefs and behaviors among those who post this content and among viewers. Online pornography appears to be more problematic for youth than off-line sources. Given the vast and increasing amount of time youth spend onli…

Children and Adolescents and Digital Media.
Today's children and adolescents are immersed in both traditional and new forms of digital media. Research on traditional media, such as television, has identified health concerns and negative outcomes that correlate with the duration and content of viewing. Over the past decade, the use of digital media, including interactive and social media, has grown, and research evidence suggests that these newer media offer both benefits and risks to the health of children and teenagers. Evidence-based benefits identified from the use of digital and social media include early learning, exposure to new ideas and knowledge, increased opportunities for social contact and support, and new opportunities to access health promotion messages and information. Risks of such media include negative health effects on sleep, attention, and learning; a higher incidence of obesity and depression; exposure to inac…

Holt A (2016)reviewMEDLINE-indexed journal, not yet read by usTrauma, violence & abuse31 citations Adolescent-to-Parent Abuse as a Form of "Domestic Violence": A Conceptual Review.
Across the Global North, adolescent-to-parent abuse (APA) is becoming recognized as a significant social problem and is receiving attention from researchers, policymakers, and practitioners who work in the intersecting fields of juvenile justice, child protection, and domestic violence. One of the key questions shaping current debates concerns the extent to which APA maps onto the contours of domestic violence, in terms of research and theory, policy, and practice. In particular, to what extent can our established ways of working with domestic violence be applied when working with APA? This article begins by reviewing definitions and prevalence rates of APA. It then considers how the problem fits into the "family conflicts" and "gender-based violence" paradigms that are most frequently used to conceptualize domestic violence. The article then examines how APA represents a similar but dis…

Mechanisms contributing to prefrontal cortex maturation during adolescence.
Adolescence is defined as a transitional period between childhood and adulthood characterized by changes in social interaction and acquisition of mature cognitive abilities. These changes have been associated with the maturation of brain regions involved in the control of motivation, emotion, and cognition. Among these regions, the protracted development of the human prefrontal cortex during adolescence has been proposed to underlie the maturation of cognitive functions and the regulation of affective responses. Studies in animal models allow us to test the causal contribution of specific neural processes in the development of the prefrontal cortex and the acquisition of adult behavior. This review summarizes the cellular and synaptic mechanisms occurring in the rodent prefrontal cortex during adolescence as a model for understanding the changes underlying human prefrontal development.

This paper provides a narrative review of the knowledge on inter-personal violence and abuse (IPVA) in adolescents' intimate relationships. It draws on the authors' own research, published reviews, and a rapid review on IPVA victimization and mental health outcomes for adolescents. The research reviewed identified associations between adolescent IPVA and substance misuse, depressive symptoms and PTSD, eating disorders and suicidal thinking, and behaviour in young people. Generally, girls appeared more likely to report severe mental health outcomes than boys. Adolescents rarely disclose IPVA to adults and delivering preventative programmes that promote knowledge and help seeking may offer a means of building on young people's tendency to seek help from friends. These preventative interventions, usually delivered in schools, need to be closely linked to support services for adolescents who…

Committee Opinion No 653 Summary: Concerns Regarding Social Media and Health Issues in Adolescents and Young Adults.
Although there are many positive aspects of social media for adolescents and young adults, there are also risks. Adolescence is a time of significant developmental changes, during which adolescents exhibit a limited capacity for self-regulation and an increased risk of susceptibility to peer pressure and experimentation. Social media can be harmful, and obstetrician-gynecologists may screen their adolescent and young adult patients for high-risk sexual behaviors, especially if sexualized text communication (sexting), exposure to pornography, online dating, or other risk-taking behaviors are present. Victims of cyberbullying and those who engage in sexting are at increased risk of sexually transmitted infections and pregnancy. The effect of social media may be considered in the differential diagnosis of myriad health problems during adolescence. Referrals to mental health care providers o…

The development of social cognition in adolescence: An integrated perspective.
Social cognitive processes are critical in navigating complex social interactions and are associated with a network of brain areas termed the 'social brain'. Here, we describe the development of social cognition, and the structural and functional changes in the social brain during adolescence, a period of life characterised by extensive changes in social behaviour and environments. Neuroimaging and behavioural studies have demonstrated that the social brain and social cognition undergo significant development in human adolescence. Development of social cognition and the social brain are discussed in the context of developments in other neural systems, such as those implicated in motivational-affective and cognitive control processes. Successful transition to adulthood requires the rapid refinement and integration of these processes and many adolescent-typical behaviours, such as peer inf…

Toward an Intersectional Approach in Developmental Science: The Role of Race, Gender, Sexual Orientation, and Immigrant Status.
Developmental theory and research have often focused on a single social identity category, for example, race or sexual orientation, and examined the consequences of that category on life outcomes. Yet intersectional models of social disadvantage (eg, Cole, 2009; Crenshaw, 1995; King, 1988) suggest that social categories combine to shape the experiences and life outcomes of individuals across life domains. In this chapter, we review empirical research that offers insight into the intersectionality of social identities across three critical developmental periods, namely, middle childhood, adolescence, and emerging adulthood. We also consider the consequences of intersecting identities across several life domains, including intergroup relations and political and civic engagement. Recognizing that the body of work on social identities is expansive, we focus our review on race/ethnicity, gend…

The dual systems model: Review, reappraisal, and reaffirmation.
According to the dual systems perspective, risk taking peaks during adolescence because activation of an early-maturing socioemotional-incentive processing system amplifies adolescents' affinity for exciting, pleasurable, and novel activities at a time when a still immature cognitive control system is not yet strong enough to consistently restrain potentially hazardous impulses. We review evidence from both the psychological and neuroimaging literatures that has emerged since 2008, when this perspective was originally articulated. Although there are occasional exceptions to the general trends, studies show that, as predicted, psychological and neural manifestations of reward sensitivity increase between childhood and adolescence, peak sometime during the late teen years, and decline thereafter, whereas psychological and neural reflections of better cognitive control increase gradually an…

Nicotine and the adolescent brain.
Adolescence encompasses a sensitive developmental period of enhanced clinical vulnerability to nicotine, tobacco, and e-cigarettes. While there are sociocultural influences, data at preclinical and clinical levels indicate that this adolescent sensitivity has strong neurobiological underpinnings. Although definitions of adolescence vary, the hallmark of this period is a profound reorganization of brain regions necessary for mature cognitive and executive function, working memory, reward processing, emotional regulation, and motivated behavior. Regulating critical facets of brain maturation are nicotinic acetylcholine receptors (nAChRs). However, perturbations of cholinergic systems during this time with nicotine, via tobacco or e-cigarettes, have unique consequences on adolescent development. In this review, we highlight recent clinical and preclinical data examining the adolescent brain…

Schizophrenia: a tale of two critical periods for prefrontal cortical development.
Schizophrenia is a disease of abnormal brain development. Considerable evidence now indicates that environmental factors have a causative role in schizophrenia. Elevated incidence of the disease has been linked to a wide range of disturbances in the prenatal environment and to social factors and drug intake during adolescence. Here we examine neurodevelopment of the prefrontal cortex in the first trimester of gestation and during adolescence to gain further insight into the neurodevelopmental processes that may be vulnerable in schizophrenia. Early embryonic development of the prefrontal cortex is characterized by cell proliferation, including renewal of progenitor cells, generation of early transient cell populations and neurogenesis of subcortical populations. Animal models show that curtailing early gestational cell proliferation produces schizophrenia-like pathology in the prefrontal…

Impact of social norms and social support on diet, physical activity and sedentary behaviour of adolescents: a scoping review.
The prevalence of non-communicable diseases (NCDs) in adulthood is rapidly increasing, and it is essential that risk factors for NCDs be addressed in adolescence, both for the health of individuals during adolescence and for their health in later life. These risk factors include diet, physical activity and sedentary behaviour. No literature has been published that comprehensively summarizes the impact of social norms and social support on these behaviours among adolescents. Therefore, a scoping review was conducted to determine the extent of recent (since 2000) literature available on this topic. A comprehensive search strategy was used to search PubMed and EMBASE for eligible reviews. Review papers (narrative reviews, systematic and non-systematic reviews) published in English in peer-reviewed journals from 2000 to February 2013 were included in the overview. Two of the authors screened…

Sharp C, Fonagy P (2015)reviewMEDLINE-indexed journal, not yet read by usJournal of child psychology and psychiatry, and allied disciplines128 citations Practitioner Review: Borderline personality disorder in adolescence--recent conceptualization, intervention, and implications for clinical practice.
Background: The past decade has seen an unprecedented increase in research activity on personality disorders (PDs) in adolescents. The increase in research activity, in addition to major nosological systems legitimizing the diagnosis of borderline personality disorder (BPD) in adolescents, highlights the need to communicate new research on adolescent personality problems to practitioners.
Scope: In this review, we provide up-to-date information on the phenomenology, prevalence, associated clinical problems, etiology, and intervention for BPD in adolescents. Our aim was to provide a clinically useful practitioner review and to dispel long-held myths about the validity, diagnostic utility, and treatability of PDs in adolescents.
Findings and conclusion: Alongside providing up-to-date information on the phenomenology, prevalence, and etiology, we also report on associated clinical problems …

Sibling relationships as sources of risk and resilience in the development and maintenance of internalizing and externalizing problems during childhood and adolescence.
Sibling relationships are a unique and powerful context for children's development, characterized by strong positive features, such as warmth and intimacy, as well as negative qualities like intense, potentially destructive conflict. For these reasons, sibling interactions may be both a risk and a protective factor for the development and maintenance of emotional and behavioral dysfunction. We review evidence indicating that sibling interactions are linked to internalizing and externalizing symptoms and identify possible mechanisms for these associations. Sibling conflict contributes uniquely to symptomatology and may be particularly problematic when accompanied by lack of warmth, which is generally associated with decreased internalizing and externalizing problems. On the other hand, greater warmth can be associated with heightened externalizing symptoms for later-born children who may …

Borderline personality disorder in adolescence.
Borderline personality disorder (BPD) is a common and severe mental disorder that is associated with severe functional impairment and a high suicide rate. BPD is usually associated with other psychiatric and personality disorders, high burden on families and carers, continuing resource utilization, and high treatment costs. BPD has been a controversial diagnosis in adolescents, but this is no longer justified. Recent evidence demonstrates that BPD is as reliable and valid among adolescents as it is in adults and that adolescents with BPD can benefit from early intervention. Consequently, adolescent BPD is now recognized in psychiatric classification systems and in national treatment guidelines. This review aims to inform practitioners in the field of adolescent health about the nature of BPD in adolescence and the benefits of early detection and intervention. BPD diagnosis and treatment …

Adolescent alcohol exposure and persistence of adolescent-typical phenotypes into adulthood: a mini-review.
Alcohol use is typically initiated during adolescence, which, along with young adulthood, is a vulnerable period for the onset of high-risk drinking and alcohol abuse. Given across-species commonalities in certain fundamental neurobehavioral characteristics of adolescence, studies in laboratory animals such as the rat have proved useful to assess persisting consequences of repeated alcohol exposure. Despite limited research to date, reports of long-lasting effects of adolescent ethanol exposure are emerging, along with certain common themes. One repeated finding is that adolescent exposure to ethanol sometimes results in the persistence of adolescent-typical phenotypes into adulthood. Instances of adolescent-like persistence have been seen in terms of baseline behavioral, cognitive, electrophysiological and neuroanatomical characteristics, along with the retention of adolescent-typical s…

Mental health in adolescents with Type 1 diabetes: results from a large population-based study.
Background: Diabetes has previously been linked to mental health problems in adolescents, but more recent studies have yielded mixed findings. The aim of the current study was to compare symptoms of mental health problems, sleep and eating disturbances in adolescents with and without Type 1 diabetes in a population based sample.
Methods: Data were taken from the youth@hordaland study, a large population based study in Hordaland County in Norway conducted in 2012. In all, 9883 adolescents aged 16-19 years (53% girls) provided self-reported data on both diabetes and a range of instruments assessing mental health symptoms, including depression, anxiety, obsessive-compulsive behaviours, hyperactivity, impulsivity, inattention, perfectionism, resilience, sleep problems and eating behaviour.
Results: 40 adolescents were classified as having Type 1 diabetes (prevalence 0.4%). We found that adol…

Screening and brief intervention for alcohol and other abuse.
Substance use is the most common health risk behavior among adolescents and is one of the greatest threats to their current and future health. Universal screening of adolescents in general medical settings can be instrumental in identifying substance use early, before further problems develop and when BIs are more likely to be effective. Screening in and of itself may have some therapeutic effect. Brief screening tools feasible for use by busy medical offices to quickly and reliably assess adolescent risk for a substance use disorder now are available. A recent study found that a physician-conducted CRAFFT screen interview required an average of 74 seconds to complete, whereas a computer self-administered version took an average of 49 seconds. The CRAFFT and AUDIT tools currently have the most evidence for validity among adolescents, whereas the validity of other widely used tools such a…

Muris P, Meesters C (2014)reviewMEDLINE-indexed journal, not yet read by usClinical child and family psychology review84 citations Small or big in the eyes of the other: on the developmental psychopathology of self-conscious emotions as shame, guilt, and pride.
The self-conscious emotions of guilt, shame, and pride typically occur when people evaluate their own self through the eyes of another person. This article will first of all discuss the nature and function of self-conscious emotions, and describe their developmental course in children and adolescents. Then, a number of variables are discussed that are thought to increase young people's proneness to experience self-conscious emotions. Following this, the empirical evidence on the relationships between guilt, shame, and pride and various types of psychopathology in children and adolescents will be summarized. A model is presented to explain why these self-conscious emotions are associated with a diversity of psychopathological outcomes. Finally, recommendations for clinical practice are made in terms of assessment and interventions targeting the origins and sequelae of self-conscious emoti…

Selemon LD (2013)reviewMEDLINE-indexed journal, not yet read by usTranslational psychiatry278 citations A role for synaptic plasticity in the adolescent development of executive function.
Adolescent brain maturation is characterized by the emergence of executive function mediated by the prefrontal cortex, e.g., goal planning, inhibition of impulsive behavior and set shifting. Synaptic pruning of excitatory contacts is the signature morphologic event of late brain maturation during adolescence. Mounting evidence suggests that glutamate receptor-mediated synaptic plasticity, in particular long-term depression (LTD), is important for elimination of synaptic contacts in brain development. This review examines the possibility (1) that LTD mechanisms are enhanced in the prefrontal cortex during adolescence due to ongoing synaptic pruning in this late developing cortex and (2) that enhanced synaptic plasticity in the prefrontal cortex represents a key molecular substrate underlying the critical period for maturation of executive function. Molecular sites of interaction between e…

Brain development during adolescence: neuroscientific insights into this developmental period.
Background: Adolescence is the phase of life between late childhood and adulthood. Typically, adolescents seek diversion, new experiences, and strong emotions, sometimes putting their health at serious risk. In Germany, for example, 62% of all deaths among persons aged 15 to 20 are due to traumatic injuries. Neuroscientific explanations have been proposed for typical adolescent behavior; with these explanations in mind, one can derive appropriate ways of dealing with adolescents.
Method: We selectively review pertinent articles retrieved from the PubMed database about the structural and functional development of the brain in adolescence.
Results: New findings in developmental psychology and neuroscience reveal that a fundamental reorganization of the brain takes place in adolescence. In postnatal brain development, the maximum density of gray matter is reached first in the primary sensor…

Research on subjective well-being indicates that it is associated with academic success and positive school functioning. Despite a wealth of empirical research demonstrating the benefits of interventions aimed at increasing middle and high school students' well-being, few educational institutions have adopted evidence-based curricula that address this construct as a means of promoting future academic and social achievement. In addition, numerous studies have begun to identify several factors that contribute to well-being and thus have helped children and adolescents to be successful in both academic and social domains. These critical factors include personal goal setting, structured mentoring or life coaching, increasing gratitude, problem solving, and interpersonal skills. The present article provides a broad discussion of relevant research findings on these factors and advocates for th…

[The European Psychiatric Association (EPA) guidance on suicide treatment and prevention].
Unlabelled: Suicide is a major public health problem in the WHO European Region accounting for over 150,000 deaths per year. Suicidal crisis: Acute intervention should start immediately in order to keep the patient alive.
Diagnosis: An underlying psychiatric disorder is present in up to 90% of people who completed suicide. Comorbidity with depression, anxiety, substance abuse and personality disorders is high. In order to achieve successful prevention of suicidality, adequate diagnostic procedures and appropriate treatment for the underlying disorder are essential.
Treatment: Existing evidence supports the efficacy of pharmacological treatment and cognitive behavioural therapy (CBT) in preventing suicidal behaviour. Some other psychological treatments are promising, but the supporting evidence is currently insufficient. Studies show that antidepressant treatment decreases the risk for su…
