Study Objectives: Perfectionism is a possible risk factor for insomnia, yet longitudinal evidence of this relationship in adolescence is lacking. Cross-sectional evidence suggests the nature of the relationship may differ based on biological sex, and the form of perfectionism, since socially prescribed and self-oriented critical perfectionism are conceptualised as maladaptive for wellbeing, while self-oriented striving may be adaptive or neutral. This study aimed to investigate longitudinal bidirectional relationships between total perfectionism, and sub-forms of perfectionism (i.

Article Synopsis
  • Body dysmorphic disorder (BDD) affects many adolescents, but there's limited research on its impact on young people, prompting this study.
  • The study compared 26 adolescents with BDD to 27 with anxiety disorders and 25 without mental disorders, focusing on their perceptions of peer relationships, victimization, support, and social media use.
  • Findings revealed that adolescents with BDD and anxiety perceived less peer support and reported more distress from appearance victimization, while also spending more time on social media and engaging in appearance comparisons.

Anxiety disorders are common, emerge during childhood, and pose a significant burden to society and individuals. Research evaluating the impact of anxiety on functional impairment and quality of life (QoL) is increasing; however, there is yet to be a systematic review and meta-analysis of these relationships in pediatric samples. This systematic review and meta-analysis were conducted to determine the extent of impairments in functioning and QoL that young people with anxiety disorders experience relative to their healthy peers, as well as sociodemographic and clinical moderators of these relationships.

Adolescence is a time of heightened vulnerability for both peer victimization (PV) and internalizing symptoms. While the positive association between them is well established, there is little understanding of the mechanisms underpinning this relationship. To address this gap, the current study aimed to investigate sleep hygiene and school night sleep duration as individual and sequential mediators of the relationship between PV and both depressive and social anxiety symptoms during pre- to mid-adolescence.

Research has consistently shown that more physically attractive individuals are perceived by others to be happier and better psychologically adjusted than those perceived as less attractive. However, due to the lack of longitudinal research in adolescents, it is still unclear whether poor mental health predicts or is predicted by either objective or subjective attractiveness during this critical developmental period. The purpose of the current study was to examine prospective bidirectional associations between both subjective and objective ratings of attractiveness, life satisfaction and symptoms of social anxiety, depression and eating disorders (i.

Study Objectives: Parental warmth in adolescence protects sleep in early adulthood, yet the nature, directions, and mechanisms of this association across adolescence are unknown. This study examined parental warmth, adolescent sleep hygiene and sleep outcomes (morning/eveningness, school night sleep duration, and daytime sleepiness) across five annual waves, spanning four years, using a cross-lagged panel design.

Methods: Adolescents and one primary caregiver (96% mothers) completed questionnaires assessing parental warmth (child- and parent-report) and adolescent sleep hygiene and sleep (child-report), across five annual waves: Wave 1 (N = 531, Mage = 11.

A considerable body of research in adults has demonstrated that anxiety disorders are characterised by attentional biases to threat. Findings in children have been inconsistent. The present study examined anxiety-related attention biases using eye tracking methodology in 463 preadolescents between 10 and 12 years of age, of whom 92 met criteria for a DSM-5 anxiety disorder and 371 did not.

Research into the aetiology, maintenance, and treatment of obsessive-compulsive disorder (OCD) has largely been informed by models of anxiety. However, non-experimental research suggests that some individuals may engage in compulsions to neutralise shame, with repugnant obsessions associated with more shame than other obsessions. Violent and sexual obsessions and shame have been linked with poorer treatment outcomes, and thus, treatment modifications are needed.

Much of the literature investigating the association between coping and psychopathology is cross-sectional, or associations have been investigated in a unidirectional manner; hence, bidirectionality between coping and psychopathology remains largely untested. To address this gap, this study investigated bidirectional relations between coping and psychopathology during pre-adolescence. Participants (N = 532, 51% male) and their primary caregiver both completed questionnaires assessing pre-adolescents' coping (i.

The restrictions put in place to contain the COVID-19 virus have led to widespread social isolation, impacting mental health worldwide. These restrictions may be particularly difficult for adolescents, who rely heavily on their peer connections for emotional support. However, there has been no longitudinal research examining the psychological impact of the COVID-19 pandemic among adolescents.

Objectives: Preadolescent social media use is normative and could influence mental health. This study investigated: (a) Differences between preadolescent users and non-users of various social media platforms on mental health, (b) unique links between time spent on those platforms, appearance-based activities on social media, and mental health, and (c) the moderating role of biological sex on those relationships.

Method: Preadolescent youth (N = 528; 50.

The adolescent developmental stage appears to be a sensitive period for the onset of several particular forms of mental disorder that are characterised by heightened emotionality and social sensitivity and are more common in females than males. We refer to these disorders (social anxiety disorder, generalised anxiety disorder, eating disorders, major depression) collectively as the social-emotional disorders. The aim of this paper is to address an important question in the understanding of social-emotional disorders - why do these disorders commonly begin during adolescence? We present a conceptual model that describes some of the key changes that occur during adolescence and that addresses some hypothesised ways in which these changes might increase risk for the development of social-emotional disorders.

Repetitive negative thinking (RNT) is a key risk and maintenance factor for many psychological disorders and is considered a transdiagnostic process. However, there are few disorder-neutral measures that assess RNT in adults, only 1 of moderate length considered suitable for children, and none that are validated for both children and adults. This study aimed to address this gap by developing a brief measure of RNT that can be used with both children and adults and can be quickly administered in research and clinical contexts.

This research investigated associations between socially prescribed and self-orientated perfectionism, and the social functioning of 510 preteens (M = 11.2). The study focused on predictions from the Perfectionism Social Disconnection Model (PSDM) by determining whether rejection sensitivity and social isolation, in that sequence, mediated the associations between both perfectionism types and mental health outcomes.

Background: D-Cycloserine has potential to enhance exposure therapy outcomes. The current study presents a preliminary randomized, placebo-controlled double-blind pilot trial of DCS-augmented one-session treatment (OST) for youth (7-14 years) with specific phobia. A secondary aim of this pilot study was to explore the effects of youth age and within-session fear reduction as potential moderators of DCS outcomes in order to generate hypotheses for a larger trial.

Anxiety and depression are highly prevalent disorders in youth. Assessments for these disorders in young people typically include clinician-administered instruments such as diagnostic interviews and parent- and youth-report questionnaires. Cognitive behavioral therapy is considered a well-established treatment for both anxiety and depression.

This article discusses considerations for adapting cognitive behavioral therapy (CBT) techniques and processes with anxious children and adolescents. To successfully deliver CBT with this population, the therapist must take into consideration the child's developmental level and other contextual factors that may affect treatment outcome. Suggested adaptions to CBT include the use of rewards, technology, and interactive activities to increase child motivation and engagement.

Background And Objectives: One-Session Treatment (OST) for specific phobias has been shown to be effective in reducing phobia severity; however, the effect of different types of co-occurring anxiety disorders on OST outcomes is unknown. The present study examined (1) the effects of co-occurring generalized anxiety disorder (GAD), social anxiety disorder (SAD), or another non-targeted specific phobia (OSP) on the efficacy of OST for specific phobias, and (2) the effects of OST on these co-occurring disorders following treatment.

Methods: Three groups of 18 youth (7-15 years) with a specific phobia and comorbid GAD, SAD, or OSP were matched on age, gender, and phobia type.

Cognitive behaviour therapy (CBT), incorporating exposure and response prevention (ERP), has received strong empirical support for the treatment of paediatric OCD, and moreover, is considered the first line treatment of choice (Geller & March, 2012). However, despite the availability of effective treatments for this chronic and debilitating disorder, only a small proportion of youth receive these evidence-based approaches. The present study aimed to examine the effectiveness of an intensive ERP-based treatment for youth OCD, using a multiple baseline controlled design.

Blood-Injection-Injury (BII) phobia is a particularly debilitating condition that has been largely ignored in the child literature. The present study examined the clinical phenomenology of BII phobia in 27 youths, relative to 25 youths with dog phobia-one of the most common and well-studied phobia subtypes in youth. Children were compared on measures of phobia severity, functional impairment, comorbidity, threat appraisals (danger expectancies and coping), focus of fear, and physiological responding, as well as vulnerability factors including disgust sensitivity and family history.

Blood-injection-injury (BII) phobia is a chronic and debilitating disorder, which has largely been neglected in the child literature. The present paper briefly reviews the aetiology of specific phobias with particular attention to BII and provides an integrated developmental model of this disorder in youth. Evidence-based treatments for child-specific phobias are discussed, and the development of a modified one session treatment (OST) approach to enhance treatment outcomes for BII phobia in children and adolescents is described.

This study aimed to examine parents' perceptions of established treatments, including cognitive behaviour therapy (CBT) and selective serotonin reuptake inhibitors (SSRIs), relative to novel treatments of D-cycloserine (DCS) and attention bias modification (ABM) augmented CBT to determine if novel treatments are perceived as more or less favorable than established treatments. Participants included parents of children with a specific phobia, enrolled in one of two randomized controlled trials of either one-session augmented DCS (n = 38, Gold Coast) or ABM augmented one-session treatment (n = 34, Brisbane), as well as parents from a community sample (n = 38). Parents of children with a specific phobia perceived CBT most favorably.
