The utility of the SCAS-C/P to detect specific anxiety disorders among clinically anxious children.

Questionnaire measures offer a time and cost-effective alternative to full diagnostic assessments for identifying and differentiating between potential anxiety disorders and are commonly used in clinical practice. Little is known, however, about the capacity of questionnaire measures to detect specific anxiety disorders in clinically anxious preadolescent children. This study aimed to establish the ability of the Spence Children's Anxiety Scale (SCAS) subscales to identify children with specific anxiety disorders in a large clinic-referred sample (N = 1,438) of children aged 7 to 12 years.

HPA AXIS RELATED GENES AND RESPONSE TO PSYCHOLOGICAL THERAPIES: GENETICS AND EPIGENETICS.

Background: Hypothalamic-pituitary-adrenal (HPA) axis functioning has been implicated in the development of stress-related psychiatric diagnoses and response to adverse life experiences. This study aimed to investigate the association between genetic and epigenetics in HPA axis and response to cognitive behavior therapy (CBT).

Methods: Children with anxiety disorders were recruited into the Genes for Treatment project (GxT, N = 1,152).

Non-replication of the association between 5HTTLPR and response to psychological therapy for child anxiety disorders.

Background: We previously reported an association between 5HTTLPR genotype and outcome following cognitive-behavioural therapy (CBT) in child anxiety (Cohort 1). Children homozygous for the low-expression short-allele showed more positive outcomes. Other similar studies have produced mixed results, with most reporting no association between genotype and CBT outcome.

Evaluating statistical and clinical significance of intervention effects in single-case experimental designs: an SPSS method to analyze univariate data.

Single-case experimental designs are useful methods in clinical research practice to investigate individual client progress. Their proliferation might have been hampered by methodological challenges such as the difficulty applying existing statistical procedures. In this article, we describe a data-analytic method to analyze univariate (i.

The anxiety severity interview for children and adolescents: an individualized repeated measure of anxiety severity.

The Anxiety Severity Interview for Children and Adolescents (ASICA) was developed for the repeated assessment of the impact of anxiety and control over anxiety symptoms. The ASICA incorporates three main components of anxiety: physical response, avoidant behaviour and anxious thoughts. The objective of this study was to evaluate the psychometric properties of the ASICA in children with anxiety disorder (n = 139, age 8-18 years) and a non-anxious control group (n = 40, age 8-18 years).

Mediators of cognitive behavioral therapy for anxiety-disordered children and adolescents: cognition, perceived control, and coping.

The purpose is to investigate whether a change in putative mediators (negative and positive thoughts, coping strategies, and perceived control over anxious situations) precedes a change in anxiety symptoms in anxiety-disordered children and adolescents receiving cognitive behavioral therapy (CBT). Participants were 145 Dutch children (8-18 years old, M = 12.5 years, 57% girls) with a primary anxiety disorder.

Temperament and parenting predicting anxiety change in cognitive behavioral therapy: the role of mothers, fathers, and children.

Objective: A considerable amount of children with anxiety disorders do not benefit sufficiently from cognitive behavioral treatment. The present study examines the predictive role of child temperament, parent temperament and parenting style in the context of treatment outcome.

Method: Participants were 145 children and adolescents (ages 8-18) with DSM-IV-TR anxiety disorders who received a 12-session CBT program and were assessed at pretreatment, posttreatment and three months follow-up.

Perceived control in clinically anxious and non-anxious children indirectly measured with the Implicit Association Procedure (IAP).

Background: Perceived control is thought to play an important role in the development and maintenance of anxiety disorders in children. The objective of the present study was to further investigate the Perceived Control Implicit Association Procedure (IAP, Hogendoorn et al., 2008) as an indirect measure of perceived control in children.

Psychometric properties of the Dutch version of the Meta-Cognitions Questionnaire-Adolescent Version (MCQ-A) in non-clinical adolescents and adolescents with obsessive-compulsive disorder.

Although the meta-cognitive model (Wells, 1997, 2000) for obsessive-compulsive disorder (OCD) has clearly influenced research and treatment of OCD, little research has been performed in youth samples. In the present study the psychometric properties of the Dutch Meta-Cognitions Questionnaire-Adolescent Version (MCQ-A; Cartwright-Hatton et al., 2004) were examined in a clinical sample of adolescents with OCD (N = 40, 12-18 years) and a non-clinical sample (N = 317; 12-18 years).

Positive thinking in anxiety disordered children reconsidered.

Negatively valenced thoughts are assumed to play a central role in the development and maintenance of anxiety. However, the role of positive thoughts in anxiety is rather unclear. In the current study we examined the role of negative and positive self-statements in the anxiety level of anxious and non-anxious children.

The time-course of threat processing in children: a temporal dissociation between selective attention and behavioral interference.

Although selective attention to threatening information is an adaptive mechanism, exaggerated attention to threat may be related to anxiety disorders. However, studies examining threat processing in children have obtained mixed findings. In the present study, the time-course of attentional bias for threat and behavioral interference was analyzed in a community sample of 8-18-year-old children (N=33) using a pictorial dot probe task.

Psychometric properties of a Dutch version of the Obsessive Beliefs Questionnaire--Child Version (OBQ-CV).

To improve research in cognitive theories of childhood OCD, a child version of the Obsessive Beliefs Questionnaire (OBQ-CV) has been developed (Coles et al., 2010). In the present study, psychometric properties of the Dutch OBQ-CV were examined in a community sample (N=547; 8-18 years) and an OCD sample (N=67; 8-18 years).

Temperament, attentional processes, and anxiety: diverging links between adolescents with and without anxiety disorders?

The present study first examined the links between reactive temperament (negative affectivity), regulative temperament (effortful control [EC]) and internalizing problems in adolescents (12-18 years) with anxiety disorders (ANX; N = 39) and without anxiety disorders (nANX; N = 35). Links differed between ANX and nANX participants. Negative affectivity predicted internalizing problems, with almost no role of EC in nANX, but a protective role of EC was found in ANX youth.

Measuring Negative and Positive Thoughts in Children: An Adaptation of the Children's Automatic Thoughts Scale (CATS).

The aim of this study is to describe the factor structure and psychometric properties of an extended version of the Children's Automatic Thoughts Scale (CATS), the CATS-Negative/Positive (CATS-N/P). The CATS was originally designed to assess negative self-statements in children and adolescents. However, positive thoughts also play a major role in childhood disorders such as anxiety and depression.

Automatic evaluations in clinically anxious and nonanxious children and adolescents.

Automatic evaluations of clinically anxious and nonanxious children (n = 40, aged 8-16, 18 girls) were compared using a pictorial performance-based measure of automatic affective associations. Results showed a threat-related evaluation bias in clinically anxious but not in nonanxious children. In anxious participants, automatic evaluations of anxiety-relevant stimuli were more negative than those of negative stimuli.

An indirect and direct measure of anxiety-related perceived control in children: the Implicit Association Procedure (IAP) and Anxiety Control Questionnaire for Children (ACQ-C).

A perceived lack of control over negative events is assumed central to the development of anxiety disorders. So far, only questionnaires were used to test this theory, but they have several disadvantages. In this study, the Implicit Association Procedure (IAP) was adapted to measure anxiety-related perceived control in an indirect way.
