Background: Children within historically disadvantaged non-Western South African communities are considered as particularly vulnerable to the development of anxiety problems. Although the need for accessible mental health interventions is evident, this need has remained unmet in a country with extreme socio-economic disparities and a lack of mental health resources. Cognitive behavioural therapy-based (CBT-based) interventions that employ brief and intensive delivery methods may overcome existing barriers to access to mental health services faced by many South African children and may ameliorate the burden placed on under-resourced mental health care services.

The Youth Anxiety Measure for DSM-5 (YAM-5) is a self- and parent-report scale specifically developed to assess symptoms of major anxiety disorders (part 1 or YAM-5-I) and specific phobias/agoraphobia (part 2 or YAM-5-II) in children and adolescents in terms of the contemporary psychiatric classification system. Since its introduction, the measure has been increasingly used in research, making it feasible to provide a summary of its psychometric properties. The present article presents a systematic review of 20 studies that employed the YAM-5, involving 5325 young participants.

The current study examined how mood affects the impact of false feedback on belief and recollection. In a three-session experiment, participants first watched 40 neutral mini videos, which were accompanied by music to induce either a positive or negative mood, or no music. Following a recognition test, they received false feedback to reduce belief in the occurrence of the events displayed in some of the videos (Session 2).

Self-compassion is assumed to have a protective role in the etiology of emotional problems in adolescents. This assumption is primarily based on correlational data revealing negative correlations between the total score on the Self-Compassion Scale (SCS) and symptom measures of anxiety and depression. Recently, however, the SCS has been criticized because this scale not only consists of items measuring compassionate self-responding (i.

The main purpose of the current studies was to examine retracted experiences in the general population from various cultural backgrounds. More specifically, in two studies, we examined the details of memory retraction experiences, the reasons for retraction, and the outcomes of retraction in participants from China and other countries, mainly the United States of America. It was found that memory retraction experiences appeared to be quite common.

Aim: The present study examined the relationship between addiction and hikikomori (extreme social withdrawal) symptoms.

Method: A group of clinically referred addiction patients ( = 31) and a group of age- and gender-matched non-clinical controls ( = 34) completed a self-report scale for measuring hikikomori symptoms (the Hikikomori Questionnaire-25) along with some other questionnaires assessing substance use (frequency and severity) and quality of life.

Results: The results showed that addiction patients displayed significantly higher levels of hikikomori symptoms than the non-clinical control (Cohen's = 3.

The present review addressed the relationship between two self-related concepts that are assumed to play a role in human resilience and well-being: self-esteem and self-compassion. Besides a theoretical exploration of both concepts, a meta-analysis ( = 76, N = 35,537 participants) was conducted to examine the magnitude of the relation between self-esteem and self-compassion and their links to indices of well-being and psychological problems. The average correlation between self-esteem and self-compassion was strong ( = 0.

This study scrutinizes the influence of attenuating beliefs about the veracity of traumatic experiences on the manifestation of intrusive recollections and the memory amplification effect. Participants were exposed to distress-inducing visual stimuli, subsequently rating their emotional status pre and post exposure. They engaged in a recognition task, identifying scenarios within the stimuli.

Purpose: The aim of the present study was to provide a comprehensive picture of temperament and personality traits as correlates of self-reported disruptive behavior problems in male and female adolescents.

Methods: Two-hundred-and-sixty-three non-clinical adolescents aged 12-18 years completed a survey containing standardized scales to measure the HEXACO personality traits, impulsivity, effortful control, Dark Triad traits, and symptoms of oppositional-defiant disorder (ODD) and conduct disorder (CD).

Results: The results showed that good traits (in particular, honesty-humility, agreeableness, and the regulative trait of effortful control) were negatively associated, while bad and ugly traits (especially impulsivity and the Dark Triad traits of psychopathy and Machiavellianism) were positively associated with symptoms of ODD and CD.

The purpose of this study was to study psychopathological and temperamental correlates of selective mutism (SM) (symptoms) in a mixed sample of non-clinical (n = 127) and clinically referred (n = 42, of whom 25 displayed the selective non-speaking behavior that is prototypical for SM) 6- to 12-year-old children. Parents completed questionnaires to measure their child's symptom levels of selective mutism, social anxiety, autism spectrum disorder, and the temperament trait of behavioral inhibition. The results first and foremost showed that SM symptoms were clearly linked to social anxiety and an anxiety-prone temperament (behavioral inhibition), but findings also suggested that autism spectrum problems are involved in the selective non-speaking behavior of children.

Although it is widely accepted that human beings have an ingrained 'need to belong,' there seem to be a substantial subset of young people who seclude themselves for most of the time at home and no longer engage in education or work, ultimately withdrawing from participation in society. In Japan, this phenomenon has been labeled as 'hikikomori,' but given its global presence it may be preferable to use the term 'extreme social withdrawal' (ESW). In this qualitative review, we provide a description and definition of ESW, provide figures on its prevalence, and discuss a number of associated concepts, including loneliness and "aloneliness," school absenteeism and dropout, the 'new' developmental stage of adultolescence, and the labor force categories of freeter ('freelance arbeiter') and NEET (a young person not in employment, education, or training).

Background And Purpose: Self-compassion is considered as a protective psychological construct that would shield against the development of emotional problems. The aim of the present study was to compare the 'protective nature' of two measures of self-compassion: the Self-Compassion Scale for Youth (SCS-Y) and the Sussex-Oxford Compassion for the Self Scale (SOCS-S).

Methods: Eighty-seven adolescents aged 12 to 18 years completed both self-compassion measures as well as scales of anxiety and depression symptoms.

In a new commentary in , Neff once again tried to defend the use of the Self-Compassion Scale (SCS) total score by arguing that compassionate and uncompassionate self-responding (CS and UCS) are part of a bipolar continuum. In this brief reaction, we refute this notion and also clarify how the continued use of the SCS total score muddies the water of research on self-compassion as a protective variable. We also illustrate how the SCS-by separating CS and UCS-can provide more valid and valuable information on protection and vulnerability within the context of psychopathology and stress than just relying on the total score of the SCS.

This study examined psychopathological correlates of implicit and explicit shame and guilt in 30 clinical and 129 non-clinical youths aged 8-17 years. Shame and guilt were measured explicitly via two self-reports and a parent report, and implicitly by means of an Implicit Association Test (IAT), while a wide range of psychopathological symptoms were assessed with questionnaires completed by children, parents, and teachers. The results showed no differences of implicit and explicit shame and guilt between the clinical and non-clinical group, implying that dysregulation of these self-conscious emotions is not per definition associated with psychopathology.

Background: There is a notable comorbidity between externalizing disorders and anxiety disorders, which may be explained by the co-occurrence of two prevalent early-onset disorders, by shared vulnerability and risk factors, or as evidence that one disorder group might be causally related to the other.

Aim: To investigate the longitudinal trajectories of externalizing disorders, their interplay with anxiety disorders, and putative predictors for symptom progression in youth.

Methods: 1053 adolescents (14-17 years) from the general population were assessed at baseline and prospectively at 2, 4, and 10-year follow-up using a standardized interview of mental disorders (DIA-X/M-CIDI) to assess "early" (oppositional-defiant disorder, conduct disorder, ADHD) and "late" (antisocial behavior, substance use disorders) externalizing disorders as well as anxiety disorders.

Article Synopsis
  • - Selective mutism (SM) is a psychiatric condition where children fail to speak in certain social situations, often due to anxiety, especially social anxiety, which is why it's classified as an anxiety disorder.
  • - A study involving 172 preschool children found positive correlations between SM, social anxiety, autistic features, and behavioral inhibition (the tendency to withdraw in unfamiliar situations).
  • - The results suggest that while social anxiety is a clear factor in SM, autism-related issues are also important, with behavioral inhibition being a crucial element in the non-speaking behavior of young children.

Selective mutism (SM) is a childhood disorder characterized by a consistent failure to speak in specific social situations (eg, school) despite speaking normally in other settings (eg, at home). This article summarizes evidence supporting the recent classification of SM as an anxiety disorder and discusses the implications of this re-classification for the assessment and treatment of SM in clinical practice. Meanwhile, clinicians should also realize that SM sometimes is a heterogeneous disorder in which other problems are also present that complicate the management of children with SM.

This experimental study examined the role of negative feedback and social rank in the experience of self-conscious emotions, shame and guilt, in typically developing children aged 8 to 13 years. Participants were tested by means of a vignette paradigm in which feedback and social rank were systematically manipulated and levels of shame and guilt were assessed after listening to each of the vignettes. In addition, children completed a set of questionnaires for measuring individual differences in shame and guilt proneness, social comparison, submissive behavior, and external shame.

Article Synopsis
  • Selective mutism (SM) is categorized under anxiety disorders, primarily linked to social anxiety, yet it can also relate to autism spectrum disorders (ASD) due to shared social challenges.* -
  • The article discusses how symptoms of ASD, particularly restricted and repetitive behaviors and interests (RRBIs), may contribute to the persistence and worsening of social difficulties in individuals with SM.* -
  • The potential connection between SM and ASD has implications for clinical practices, emphasizing the need for re-evaluation in terms of classification, assessment, and treatment strategies for affected children, while also suggesting areas for future research.*

Article Synopsis
  • This study uses a meta-analytic approach to evaluate how selective mutism (SM) is classified as an anxiety disorder in the DSM-5, combining data from 22 studies with 837 children.
  • Findings show that 80% of children with SM also have another anxiety disorder, primarily social phobia (69%), indicating that SM and anxiety disorders may not be separate conditions.
  • The study highlights a need for better research methods to assess anxiety in relation to SM, as current categorizations do not clarify the connection between the two.

This longitudinal study explored the relations between fear-enhancing parenting behaviors (modeling and threat information transmission) and children's cognitive biases and anxiety symptoms on three subsequent time points over a one-year period. Participants were 216 children aged 7-12 years (114 boys and 102 girls), and their mothers (n = 199) and/or fathers (n = 117). On each time point, children and parents completed the Parental Enhancement of Anxious Cognitions scale, which measures parental modeling and threat information transmission.

Anxiety is highly prevalent in pre-adolescent children. Distorted cognitions are characteristic for dysfunctional levels of anxiety. However, applying cognitive elements in pre-adolescent children cannot be fully ascertained, as it is not until adolescence before children can apply logical and abstract reasoning in a sophisticated manner.
