Emotion-focused parenting practices, known as parent emotion socialization, play a crucial role in shaping youth’s emotion regulation (ER) abilities. The impact of parent emotion socialization behaviors (ESB) on youth ER has been studied extensively in community samples. However, research on these relations in clinical samples is more limited, albe...

Introduction Childhood specific phobias are among the most common and earliest onset mental disorders with a lifetime prevalence of more than ten percent. Brief intensive cognitive behavioral therapy (CBT) programs such as the One-Session Treatment (OST) are found to be effective in the remission of the specific phobias following treatment, but the...

Adolescence is a critical developmental period characterized by identity exploration, including gender identity and sexual orientation. Relatedly, social anxiety disorder (SAD) is a pervasive disorder that emerges during adolescence that significantly impacts interpersonal functioning and more specifically, interpersonal skills within romantic rela...

Practicing newly acquired skills in different contexts is considered a crucial aspect of Cognitive Behavioral Therapy (CBT) for anxiety disorders (Peris et al. J Am Acad Child Adolesc Psychiatry 56:1043–1052, 2017; Stewart et al. Prof Psychol Res Pract 47:303–311, 2016). Learning to cope with feared stimuli in different situations allows for genera...

Objective To evaluate the relationship between sleep problems and psychopathologies in Brazilian preschool children. Materials and Methods The present is a cross-sectional study with162 children: 81 with sleep problems referred for treatment (mean age: 3.67 years), matched by gender/age with 81 participants without sleep problems. Sleep problems we...

Objective Parent-only cognitive-behavioural therapy (CBT) interventions have promise for youth with anxiety disorders. Fear-Less Triple P (FLTP) is one such intervention that has been found comparable to child-focused CBT. Although traditionally administered in six sessions, a one-day workshop format of FLTP was developed to improve accessibility....

Background: This study sought to evaluate the relations among expressive suppression (ES), cognitive reappraisal (CR), and stress during COVID-19 in young adults with self-reported social anxiety. We hypothesized that social anxiety would positively relate to ES but negatively relate to CR. Furthermore, we predicted that stress severity would moder...

Objective: Parent-only cognitive-behavioural therapy (CBT) interventions have promise for youth with anxiety disorders. Fear-Less Triple P (FLTP) is one such intervention that has been found comparable to child-focused CBT. Although traditionally administered in six sessions, a one-day workshop format of FLTP was developed to improve accessibility....

Childhood obsessive–compulsive disorder (OCD) is among the most prevalent and disabling mental health conditions affecting children and adolescents. Although the distress and burden associated with childhood OCD are well documented and empirically supported treatments are available, there remains an unacceptable “treatment gap” and “quality gap” in...

The aim of this study was to examine the relative effectiveness of Collaborative and Proactive Solutions (CPS) and Parent Management Training (PMT) for youth with oppositional defiant disorder (ODD) in a community setting. Based on a semi-structured diagnostic interview, 160 youth with ODD (age 7-14; 72% male; ethnicity representative of the wider...

Conduct problems and anxiety symptoms commonly co-occur among youths with oppositional defiant disorder (ODD); however, how these symptoms influence functioning and treatment outcomes remains unclear. This study examined subtypes based on these co-occurring symptoms in a clinical sample of 134 youths (Mage = 9.67, 36.6% female, 83.6% white) with OD...

ARTICLE FREE TO ACCESS AT: https://doi.org/10.1080/15374416.2022.2158842. In this editorial statement, we briefly delineated a series of observations, guidelines, and directions for future research focused on the most common outcome of multi-informant assessments of youth mental health. Discrepancies commonly occur between estimates of youth mental...

The present study followed-up adolescents with social anxiety disorder (SAD) during the COVID-19 pandemic, approximately 5-years following their participation in an Attention Bias Modification Training (ABMT) program (Ollendick et al., 2019). The current study aimed to evaluate current functioning and quality of life (QoL) during the emerging adult...

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,’ bu...

Structured and semi-structured diagnostic interviews (SDIs) are widely used to gather diagnostic information and have important utility in both research and clinical settings. However, when youth are being assessed, SDIs increase the demands on time or personnel resources and often result in high rates of discordance between informants. In the curr...

Objective The current study utilized a single case series, non-concurrent multiple baseline design to examine the efficacy of training parents via telehealth videoconferencing in exposure and response prevention (ERP) for home delivery of the treatment for their children and adolescents with obsessive compulsive disorder (OCD). Method There were n...

Fears are natural during development, but they can become a problem if they are excessive or recurring, associated with internalizing problems, such as anxiety. Although there has been literature exploring childhood fears for over a decade, there is still a lack of research using only preschoolers’ samples and association with externalizing problem...

Objective: The aim of this study was to examine predictors and moderators of behavioral improvement in children with Oppositional Defiant Disorder (ODD) following treatment with Parent Management Training (PMT) and Collaborative and Proactive Solutions (CPS). Initial problem severity, inconsistent discipline, parental attributions of child misbeha...

The current study investigated the impact of birth order on vocabulary and social language development in 1338 first-born and 1049 s-born autistic youth (M age = 9.03 years, SD = 3.57; 86.4% male) from the Simons Simplex Collection. Frequentist and Bayesian analyses revealed mixed findings in language development. There were no differences in vocab...

Background Anxiety disorders are among the most common psychiatric disorders in childhood and can develop as early as the preschool years. Therefore, providing young children who display early signs of anxiety with skills to prevent the development of later psychopathology is invaluable. The current study evaluates the effectiveness of Fun FRIENDS,...

Increasing the use of exposure by community therapists during the treatment of childhood anxiety disorders is critical to improving the quality of available treatment. The aim of the current study was to investigate whether a brief training in the delivery of an exposure-focused and technology-assisted treatment protocol increased community therapi...

Prompt, appropriate, and contingent maternal behaviors play a role in early language acquisition, as do individual differences in children's temperament. However, little work has investigated the combined influence of maternal psychosocial and child biological factors on expressive language development. The purpose of this study was to evaluate the...

Background Individuals with Social Anxiety Disorder (SAD) may be at a higher risk for negative outcomes during the COVID-19 pandemic due to isolation that is both characteristic of the disorder and also potentially exacerbated by quarantine and public health restrictions. Accordingly, we evaluated emotional and behavioral responses to stress during...

Objective Community belongingness has been shown to be related to mental health outcomes in college students; however, little work has evaluated whether community belongingness impacts treatment change, especially during the COVID-19 pandemic, when social isolation and mental health concerns are exacerbated. Accordingly, the current study evaluated...

Bibliotherapy, particularly when supplemented with therapist contact, has emerged as an effective treatment for anxiety symptoms in children. However, its effectiveness in treating specific phobias in young children has been explored in only one study which targeted nighttime fears. The current study tested a novel bibliotherapy for fears of dogs i...

Social anxiety disorder (SAD) is a debilitating disorder that emerges during adolescence and confers a significant burden on interpersonal functioning. Currently available diagnostic interviews are lengthy and generally require clinically-trained experts to administer. Consequently, the identification of clinically valid self-report measures of soc...

The need for effective treatments for obsessive-compulsive disorder (OCD) in childhood is evident given that as many as 50% of the adults with OCD report symptom onset before age 15. Despite the growing evidence supporting the efficacy of Exposure and Response Prevention (ERP) for youth with OCD, children seeking services for their OCD symptoms oft...

Background Social impairments characteristic of autism spectrum disorder (ASD) are evident in early childhood and worsen as the child matures. Though many interventions for young children exist, few specifically target social skills and involve caregivers. Aims This pilot study examined PEERS® for Preschoolers, focusing on temporal change in child...

Driving is central to adult independence and autonomy; yet most autistic young adults do not acquire driver’s licenses. It is important to understand barriers to achieving this milestone for autistic adults. Differences in negative affect and emotion dysregulation associated with autism may interfere with managing difficult driving situations. The...

Objective To examine the efficacy of weight‐adjusted D‐cycloserine (DCS) (35 or 70 mg) relative to placebo augmentation of intensive exposure therapy for youth with obsessive‐compulsive disorder (OCD) in a double‐blind, randomised controlled trial, and examine whether antidepressant medication or patient age moderated outcomes. Methods Youth (n =...

A majority of those in need of mental health care do not access it. Of those who initially access care, many attend only a handful of sessions before terminating care. Cognitive behavioral therapies (CBT)—while effective in treating a wide range of psychopathology—are often designed to last longer than the handful of sessions that individuals often...

Specific fears are a common and normal experience in the life of children and adolescents. In a substantial minority of youths, the fear for a particular stimulus or situation becomes so intense and severe that it starts to interfere with daily functioning, and in these cases the diagnosis of a specific phobia is warranted. In this chapter, we will...

Resumo Medos noturnos na infância estão associados a ansiedade, problemas de sono e problemas de comportamento diurnos. O objetivo deste artigo é apresentar um estudo de caso de uma intervenção comportamental breve para o medo noturno severo e comportamento de dormir com os pais em uma menina de oito anos de idade. O tratamento consistiu em uma ses...

Os medos noturnos em crianças podem afetar o seu sono e os seus comportamentos diurnos. Este estudo objetivou verificar em crianças em idade pré-escolar com intensos medos noturnos: 1) o conteúdo dos medos; 2) o efeito do sexo e da idade na frequência e conteúdo dos medos; e 3) os hábitos e padrões de sono e os problemas de comportamento. O estudo...

Nighttime fears in children are common, interfere with daily functioning, and result in considerable disruption in the family. The aim of the present review was to examine empirical literature from the past 25 years that investigated the assessment of nighttime fears in young children and the efficacy and effectiveness of psychosocial treatments fo...

Background Avoidance of the eye region, especially of faces showing anger, may maintain social anxiety symptoms by negatively reinforcing expectations and fears associated with social situations. Eye-tracking research, however, has yet to explicitly examine differences in attention allocation to the eye region of emotional faces among adolescents w...

In current classification systems, selective mutism (SM) is included in the broad anxiety disorders category. Indeed, there is abundant evidence showing that anxiety, and social anxiety in particular, is a prominent feature of SM. In this article, we point out that autism spectrum problems in addition to anxiety problems are sometimes also implicat...

Selective mutism (SM) is a psychiatric condition that is characterized by a failure to speak in specific social situations (e. g., at school) despite speaking normally in other situations (e.g., at home). There is abundant evidence that anxiety, and social anxiety in particular, is a prominent feature of SM, which is the main reason why this condit...

Social anxiety disorder (SAD) is commonly comorbid with autism spectrum disorder (ASD). Here, in a sample of 86 children and adolescents (MAGE = 12.62 years; 68.6% male), 28 of whom were diagnosed with ASD, 34 with SAD, and 24 with comorbid ASD and SAD, we compared parent-reported scores from the Social Responsiveness Scale-Second Edition (SRS-2; C...

Anxiety disorders are among the most common co-occurring disorders for individuals with ASD. Several adaptations to cognitive behavioral approaches have been proposed for this population (Moree & Davis, 2010). The current study examined feasibility and preliminary efficacy of an ASD-specific adaptation of one-session treatment (OST) for specific ph...

During the COVID-19 pandemic, a major educational shift took place—the transition from face-to-face instruction to remote learning. Although this transition impacted all learners, it is speculated that groups of vulnerable youth (i.e., those with neurodevelopmental disorders, in rural areas, from low-income families) would demonstrate significant d...

Objective: The aim of this study was to translate the Fear Survey Schedule for Infants-Preschoolers (FSSIP) for Brazilian Portuguese and to examine its reliability and validity for assessing fears among Brazilian preschoolers. Methods: Two-independent bilingual professionals conducted translation and back-translation of the original survey. The...

Despite the established efficacy of Parent Management Training (PMT) for conduct problems in youth, evidence suggests that up to half of all treated youth still display clinical levels of disruptive behavior post-treatment. The reasons for these unsatisfactory outcomes are poorly understood. The aim of the present review was to provide an updated a...

Background Children with an autism spectrum disorder (ASD) diagnosis have high rates of behaviors such as aggression, oppositional behaviors, and tantrums. Despite effectiveness of interventions for these behavior challenges in a considerable number of autistic children, there is little information on stakeholder perspectives about available interv...

Anxiety control beliefs (i.e., beliefs regarding one’s ability to cope with external, fear-inducing threats and internal reactions to those perceived threats) have been found to negatively predict anxiety symptoms in children and adults and to be modifiable by cognitive-behavioral therapy for anxiety disorders. The current study examines whether ch...

The most effective treatments for child and adolescent psychopathology are often family-based, emphasising the active involvement of family members beyond the referred individual. This book details the clinical skills, knowledge, and attitudes that form the core competencies for the delivery of evidence-based family interventions for a range of men...

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...

A major barrier to improving care effectiveness for mental health is a lack of consensus on outcomes measurement. The International Consortium for Health Outcomes Measurement (ICHOM) has already developed a consensus-based standard set of outcomes for anxiety and depression in adults (including the Patient Health Questionnaire-9, the Generalised An...

The purpose of this study was to compare level and type of fears in Nigerian and Kenyan children using the Fear Survey Schedule for Children, Revised (FSSC-R; [Ollendick, T.H. (1983). Reliability and validity of the Revised Fear Survey Schedule for Children (FSSC-R). Behaviour Research and Therapy, 21, 685±692.]). A total of 852 males and females b...

Background Although exposure is a key evidence-based intervention for anxiety, it is infrequently used in clinical settings. This study employed a novel training strategy, experiential learning, to improve exposure implementation. This study aimed to assess the feasibility and acceptability of experiential training and preliminary training effectiv...

Psychotherapies hold clear potential to alleviate mental health problems, yet there is no scientifically-driven consensus for how long treatment should last, how intense sessions should be, or how frequently sessions should occur. In practice, once-weekly therapy is the dominant outpatient service available to youths and adults alike, largely due t...

Social anxiety disorder (SAD) is a debilitating and often chronic psychiatric disorder that typically onsets during early adolescence. Cognitive behavior therapy (CBT), the current “gold-standard” treatment for SAD, tends to focus on threat- and fear-based systems hypothesized to maintain the disorder. Despite this targeted approach, SAD ranks amon...

Specific Phobia (SP) typically onsets in childhood and frequently predicts other mental health disorders later in life. Fortunately, childhood SP can be effectively treated with Cognitive Behaviour Therapy (CBT) including the exposure-based one session treatment (OST) approach. Despite empirical support for CBT and OST, clinicians frequently fail t...

Specific phobias are among the most prevalent anxiety disorders in children and adolescents. Although brief and intensive treatments are evidence-based interventions (Davis, Ollendick, & Öst, 2019), up to one-third of youth do not show significant change in their symptoms following these interventions. Hence, consideration of additional factors inf...

Objectives One-Session Treatment (OST), a three-hour treatment which includes psychoeducation, exposure, participant modeling, cognitive challenges, and positive reinforcement, has been shown to be effective for the treatment of childhood phobias. Several comorbid anxiety conditions such as Generalized Anxiety Disorder and Social Anxiety Disorder h...

Objective: Sluggish Cognitive Tempo (SCT), characterized by lethargy and daydreaming, has most commonly been studied in community samples and in youth with Attention-Deficit/Hyperactivity Disorder (ADHD). Despite shared neurodevelopmental symptoms with ADHD, few studies have investigated SCT in Autism Spectrum Disorders (ASD). The current study inv...

Objective: We compared clinic-referred youth with ADHD + sluggish cognitive tempo (SCT; n = 34), ADHD Only (n = 108), and SCT Only (n = 22) on demographics, co-occurring symptomatology, comorbid diagnoses, and social functioning. Method: In total, 164 youth (age = 6-17 years, M = 9.97) and their parent(s) presented to an outpatient clinic for a psy...

Attention bias, conceptualized to be involved in the development and maintenance of SAD, may differentiate teens with SAD from those without. Although SAD typically emerges during adolescence, eye-tracking research has not explicitly focused on biased attention in adolescents with SAD relative to healthy controls, using stimuli specifically develop...

A number of intervention models aimed at addressing Autism Spectrum Disorder (ASD)-related behaviors require caregivers to perform intensive and oftentimes extended protocols (Bearss et al. in Clin Child Fam Psychol Rev 18(2):170–182, 2015). Though a number of research findings describe how characteristics of the child with ASD affect the mental he...

Although attention bias (AB) toward threat has been associated with Social Anxiety Disorder (SAD), concerns regarding the ability of current measures to detect change in AB following treatment exist. We sought to examine change in bias, as measured via eye-tracking, in adolescents with SAD receiving either attention-bias modification training (ABMT...

This case study illustrates a brief, intensive, cognitive behavioral therapy (CBT) for a young male client with a specific phobia of dogs and comorbid autism spectrum disorder (ASD). CBT has been shown to be an effective treatment for anxiety in children with ASD; however, this work has not often been extended to children with language impairment....

Successfully landing and then negotiating for your first position is an exciting and challenging task. In this paper, we use a narrative review to present the literature on gender and negotiation with a focus on academic psychology work contexts.

Autism spectrum disorder (ASD) is a common neurodevelopmental disorder affecting approximately 1 in 59 children (Baio et al. MMWR Surveillance Summaries, 67(6), 1, 2018). A commonly experienced psychiatric comorbidity in ASD is anxiety. Although this is known, little research has been done on the specific issues concerning specific phobia in ASD, e...

Objective: Very few controlled trials have evaluated targeted treatment methods for childhood selective mutism (SM); the availability of evidence-based services remains limited. This study is the first controlled trial to evaluate an intensive group behavioral treatment (IGBT) for children with SM. Method: Twenty-nine children with SM (5–9 years; 7...

Social anxiety disorder (SAD) is a common and impairing condition that emerges in early adolescence, confers significant interpersonal disability and often persists into adulthood. Prevailing interventions for socially anxious youth are largely based on cognitive-behavioral models originally developed in adult samples, but produce only modest rates...

Although cognitive behavioral therapy (CBT) is effective for childhood anxiety disorders, approximately 40% of youth remain anxious after treatment. Metacognitive therapy (MCT-c) for children with generalized anxiety disorder (GAD) has shown promising effects. The present study aimed to examine if CBT and MCT-c show differential effects in children...

Background Comorbidity of anxiety and autism spectrum disorder (ASD) in children and adolescents is well-documented. Preliminary evidence suggests rates of comorbidity in adults with ASD may be comparable. Little is known about the manifestation of anxiety symptoms in adults with ASD or the potential for these symptoms to impact quality of life in...

One-session treatment is a well-established evidence-based treatment for specific phobias in youths that incorporates reinforcement, cognitive challenges, participant modeling, psychoeducation, and skills training into a single, massed session of graduated exposure. This review begins by briefly examining the phenomenology, etiology, epidemiology,...

Objectives This study had two major aims: (1) to explore the relationship between sleep related difficulties and behavioral and emotional problems in young children, and (2) to identify predictors of child fear and problematic sleep behaviors. Methods Sixty-eight children (34 boys), ages 4–6 years (M = 4.9, SD = 0.9) who experienced nighttime fear...

Little research has focused on the measurement of specific facets of social anxiety disorder (SAD) in adolescents. In this study, we report on the Social Anxiety Questionnaire for Children (SAQ-C; Caballo et al. 2016), a 24-item questionnaire which assesses six facets of social anxiety in youth: 1) Speaking in public/Interactions with teachers, 2)...

Fear and anxiety are conceptualized as responses to acute or potential threat, respectively. Adult twin studies found substantial interplay between genetic and environmental factors influencing fear disorders (phobias) and anxiety disorders. Research in children, however, has largely examined these factors independently. Thus, there exists a substa...

Studies on the relationship between separation anxiety disorder (SAD) in childhood and panic disorder (PD) in adolescence and adulthood have yielded results which suggest a common underlying vulnerability for both disorders. In this study, we examined whether one such possible vulnerability—anxiety sensitivity—differed for youth diagnosed with SAD...
