Age‐Related Effects on Self‐Focused Attention Across Adolescence and the Relationship With Symptoms of Body Dysmorphia, Social Anxiety and Depression
INTRODUCTION: Adolescence is a critical period for the development of several emotional disorders, including body dysmorphic disorder (BDD), social anxiety disorder (SAD) and depression. It has been suggested that this may be partly due to developmental changes in self-referential processing, including self-focused attention (SFA). However, to date little is known about normative changes in self-focused attention across adolescence. This study in…
The hidden burden: Self-reported irritability in adolescent girls signals higher psychiatric risk
Age, sex, and informant are sources of heterogeneity in irritability reporting, and must be considered in the assessment and understanding of irritability-related psychopathology. Longitudinal design studies with comprehensive assessments of irritability across a broad age range are warranted to elucidate its developmental trajectory and causal relationships with other psychopathological symptoms
A Phenomenological Approach to Expectancy Violation in Social Anxiety Disorder
Expectancy refers to what an individual anticipates will happen in a given situation. Usually, one forms expectations for social interactions by drawing on social norms and past interactions or observations of others. The expectations of those with a social anxiety disorder, however, can be off-kilter, with social expectations that are unrealistically negative. Expectancy violation theory (EVT) suggests that disrupting the negative expectations o…
Practitioner Review: Assessment and treatment of body dysmorphic disorder in young people
Body dysmorphic disorder (BDD) is a relatively common and highly impairing mental disorder that is strikingly underdiagnosed and undertreated in Child and Adolescent Mental Health Services (CAMHS). The only clinical guidelines for the management of BDD in youth were published nearly 20 years ago, when empirical knowledge was sparse. Fortunately, there has been a surge in research into BDD over the last 10 years, shedding important insights into t…
A Psychometric Evaluation of the Body Image Questionnaire Child and Adolescent Version
Body dysmorphic disorder (BDD) typically develops during adolescence, but there has been little research evaluating assessment tools for BDD in youth. This study sought to provide a comprehensive psychometric evaluation of a brief self-report questionnaire of BDD symptoms, the Body Image Questionnaire Child and Adolescent version (BIQ-C), in both clinical and non-clinical adolescent samples. Properties of the BIQ-C were examined in 479 adolescent…
Maternal Accommodation of Adolescent Body Dysmorphic Disorder: Clinical Correlates and Association with Treatment Outcomes
Family accommodation (FA) is widely-recognised as an important clinical phenomenon in obsessive-compulsive disorder (OCD) and anxiety disorders, and is related to poorer treatment outcomes. However, FA has not been quantitatively explored in Body Dysmorphic Disorder (BDD). The aim of this study was to investigate the patterns and correlates of maternal accommodation in adolescent BDD, and its association with treatment outcomes. Participants were…
A cross‐lagged twin study of emotional symptoms, social isolation and peer victimisation from early adolescence to emerging adulthood
BACKGROUND: Emotional symptoms, such as anxiety and depressive symptoms, are common during adolescence, often persist over time, and can precede the emergence of severe anxiety and depressive disorders. Studies suggest that a vicious cycle of reciprocal influences between emotional symptoms and interpersonal difficulties may explain why some adolescents suffer from persisting emotional symptoms. However, the role of different types of interperson…
A multivariate genetic analysis of anxiety sensitivity, environmental sensitivity and reported life events in adolescents
Background Despite being considered a measure of environmental risk, reported life events are partly heritable. One mechanism that may contribute to this heritability is genetic influences on sensitivity, relating to how individuals process and interpret internal and external signals. The aim of this study was to explore the genetic and environmental overlap between self‐reported life events and measures of sensitivity. Methods At age 17, 2,939 i…
Practitioner Review: Differential susceptibility theory: might it help in understanding and treating mental health problems in youth
Diathesis‐stress models conceptualise individual differences in propensity for psychopathology as an interaction between environmental risk factors and intra‐individual vulnerabilities. In contrast, the differential susceptibility theory and related frameworks view intra‐individual differences as variations in sensitivity to the environments rather than merely vulnerability to them. Specifically, they suggest that more sensitive individuals are m…
Aetiology of shame and its association with adolescent depression and anxiety: Results from a prospective twin and sibling study
BACKGROUND: Shame is considered a maladaptive self-conscious emotion that commonly co-occurs alongside depression and anxiety. Little is known, however, about the aetiology of shame and its associations with depression and anxiety. We estimated, for the first time, genetic and environmental influences on shame and on its associations with depression and anxiety in adolescence. METHODS: = 16.97, SD = 1.64, age range: 14-23). Participants completed…
Psychometric Evaluation of the Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder for Adolescents (BDD-Ybocs-A)
The Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder for Adolescents (BDD-YBOCS-A) is a clinician-rated measure of BDD symptom severity in youth. Despite widespread use in both research and clinical practice, its psychometric properties have not been formally evaluated. The current study examined the factor structure, reliability, validity, and sensitivity to change of the BDD-YBOCS-A in 251 youths with BDD attending tw…
Reciprocal links between anxiety sensitivity and obsessive–compulsive symptoms in youth: A longitudinal twin study
BACKGROUND: Anxiety sensitivity, the tendency to fear the symptoms of anxiety, is a key risk factor for the development anxiety disorders. Although obsessive-compulsive disorder was previously classified as an anxiety disorder, the prospective relationship between anxiety sensitivity and obsessive-compulsive symptoms (OCS) has been largely overlooked. Furthermore, a lack of genetically informative studies means the aetiology of the link between a…
The Work and Social Adjustment Scale, Youth and Parent Versions: Psychometric Evaluation of a Brief Measure of Functional Impairment in Young People
The Work and Social Adjustment Scale (WSAS) is a brief global measure of functional impairment that is widely used in adult health. We have adapted the WSAS for its use in youth, the WSAS-Youth version (WSAS-Y) and WSAS-Parent version (WSAS-P). This study evaluated the psychometric properties of the scale. The internal consistency, factor structure, convergent and divergent validity, test-retest reliability and sensitivity to change of the WSAS-Y…
An Evaluation of a New Autism-Adapted Cognitive Behaviour Therapy Manual for Adolescents with Obsessive–Compulsive Disorder
Obsessive-compulsive disorder (OCD) and autism spectrum disorder (ASD) frequently co-occur. Standard cognitive behaviour therapy (CBT) for OCD outcomes are poorer in young people with ASD, compared to those without. The aim of this naturalistic study was to evaluate the effectiveness of a novel adolescent autism-adapted CBT manual for OCD in a specialist clinical setting. Additionally, we examined whether treatment gains were maintained at 3-mont…
