Evidence for retarded extinction of aversive learning in anxious children

The habituation to intense acoustic stimuli and the acquisition of differentially conditioned fear were assessed in 53 clinically anxious and 30 non-anxious control children and young adolescents. Anxious children tended to show larger electrodermal responses during habituation, but did not differ in blink startle latency or magnitude. After acquisition training, non-anxious children rated the CS + as more fear provoking and arousing than the CS- whereas the ratings of anxious children did not differ. However, anxious children rated the CS + as more fear provoking after extinction, a difference that was absent in non-anxious children. During extinction training, anxious children displayed larger blink magnitude facilitation during CS + and a trend towards larger electrodermal responses, a tendency not seen in nonanxious children. These data suggest that extinction of fear learning is retarded in anxious children. (c) 2005 Elsevier Ltd. All rights reserved.

Early intervention for children and their parents following paediatric accidental injury

This study was undertaken to develop and evaluate the efficacy of an early intervention for children who had been injured in an accident. The aim of the intervention was to prevent the development of longterm psychological consequences. Brochures were developed for children, adolescents, and their parents. These brochures detailed common responses to trauma (and normalized such responses), and suggestions for minimizing any post-trauma distress. Participants were children aged 7-15 admitted to hospital for traumatic injury. The intervention was delivered to one of two hospitals, within 72 hours of the trauma. 103 children and parents participated in the study. The parents and children completed structured interviews and questionnaires 2 weeks, 4-6 weeks and 6 months post-trauma. Outcome analyses also indicated that the intervention reduced parental distress at 4-6 weeks post-trauma. The intervention did not impact significantly on child adjustment over this time period. Results of the 6 month follow-up suggested that the intervention resulted in an amelioration of child anxiety from one to six months post-trauma, whereas the controls exhibited an increase in anxiety over this time period. Overall, it was concluded that the early intervention is a simple, practical, and cost-effective method of reducing child and parent distress post-trauma.

Family and group cognitive behavior therapy: Evaluation of treatment outcome and treatment specificity

This dissertation examined the efficacy of family cognitive behavior treatment (FCBT) and group cognitive behavior treatment (GBCT) for reducing anxiety disorders in children and adolescents using several approaches: clinical significant change, equivalence testing, and analyses of variance. It also examined treatment specificity in terms of targeting family/parents (in FCBT) and peers/group (in GCBT) contextual variables using two main approaches: analyses of variance and structural equation modeling (SEM). The sample consisted of 143 children and their parents who presented to the Child Anxiety and Phobia Program housed within the Child and Family Psychosocial Research Center at Florida International University. Diagnostic interviews and questionnaires were administered to assess youth anxiety. Questionnaires were administered to assess child and parent views of family/parents and peers/group contextual variables. In terms of clinical significant change, results indicated that 84.6% of youth in FCBT and 71.2% of youth in GBCT no longer met diagnostic criteria for their primary/targeted anxiety disorder. In addition, results from analyses of variance indicated that FCBT and GCBT were both efficacious in reducing anxiety disorders in youth across both child and parent ratings. Results using both analyses of variance and structural equation modeling also indicated that there was no meaningful treatment specificity between FCBT and GCBT in terms of either family/parents or peers/group contextual variables. That is, child social skills improved in GCBT in which these skills were targeted and in FCBT in which these skills were not targeted; parenting skills improved in FCBT in which these skills were targeted and in GCBT in which these skills were not targeted. Clinical implications and future research recommendations are discussed.

Evaluating the external validity of comorbid disorders in youth using rating scales and behavior observations

To evaluate the theoretical underpinnings of current categorical approaches to classify childhood psychopathological conditions, this dissertation examined whether children with a single diagnosis of an anxiety disorder (ANX only) and children with an anxiety diagnosis comorbid with other diagnoses (i.e., anxiety + anxiety disorder [ANX + ANX], anxiety + depressive disorder [ANX + DEP], and anxiety + disruptive disorder [ANX + EXT]) could be differentiated using external validation criteria of clinical phenomenology (i.e., levels of anxiety, depression, and internalizing, externalizing and total behavior problems). This study further examined whether the four groups could be differentiated in terms of their interaction patterns with their parents and peers, respectively. The sample consisted of 129 youth and their parents who presented to the Child Anxiety and Phobia Program (CAPP) housed within the Child and Family Psychosocial Research Center at Florida International University, Miami. Youth were between the ages of 8 and 14 years old. A battery of questionnaires was used to assess participants' clinical presentation in terms of levels of anxiety, depression, and internalizing and externalizing symptoms. Family and peer interaction were evaluated through rating scales and through behavior observation tasks. Statistics based on the parameter estimates of the structured equation models indicated that all the comorbid groups were significantly different from the pure anxiety disorder group when it came to depression indices of clinical phenomenology. Further, significant differences appeared mainly in terms of the ANX + DEP comorbid group relative to the other comorbid groups. In terms of Parent-child interaction the ANX + EXT and the ANX + DEP comorbid groups were differentiated from the pure anxiety disorder and ANX + ANX comorbid group when it came to the appraisal of the parent/child relationship by the parent, and the acceptance subscale according to the mother report. In terms of peer-child interaction the ANX + EXT and the ANX + DEP comorbid groups were statistically significantly different from the pure anxiety disorder only when it came to the positive interactions and the social skills as rated by mother. Limitations and future research recommendations are discussed.

Psychologische Inflexibiliteit bij Kinderen: Invloed op de Relatie tussen en de Samenhang met Gepest worden en (Sociale) Angst

Pesten komt voor op alle scholen en kan psychosociale gevolgen hebben zoals (sociale) angst klachten. Op cognitieve gedragstherapie gebaseerde interventies hebben dikwijls de voorkeur bij behandeling van de klachten. De cognitieve vaardigheden van kinderen van 8 tot 11 jaar schieten echter soms tekort om optimaal te kunnen profiteren van cognitieve therapie. Acceptance and Commitment Therapy (ACT) zet in op het vergroten van de psychologische flexibiliteit en is mogelijk een geschikte alternatieve therapie voor kinderen. In de huidige studie werd onderzocht of psychologische inflexibiliteit een onderliggend probleem vormt bij kinderen die angsten hebben of dat gepest worden de kwetsbaarheid voor psychologische inflexibiliteit vergroot. Er werd een positieve samenhang tussen de variabelen psychologische inflexibiliteit, (sociale) angst en gepest worden verwacht. Tevens werd verwacht dat de positieve samenhang tussen gepest worden en (sociale) angst wordt gemodereerd door psychologische inflexibiliteit. Aan 126 kinderen, 66 jongens en 60 meisjes in de leeftijd van 8 tot 11 jaar, afkomstig van basisscholen in Zuid-Nederland werd door de ouders toestemming verleend voor deelname. Eenmalig werden een drietal zelfrapportage vragenlijsten klassikaal aan de kinderen voorgelegd. (Sociale) angst werd gemeten met de Screen for Child Anxiety Related Emotional Disorders-71 (SCARED-71), gepest worden werd gemeten met de Personal Experience Checklist-32 (PECK-32) en psychologische inflexibiliteit werd gemeten met de Avoidance and Fusion Questionnaire for Youth (AFQ-Y). Er werd een positieve samenhang gevonden tussen psychologische inflexibiliteit, (sociale) angst en gepest worden. Een moderatie effect van psychologische inflexibiliteit op de relatie tussen gepest worden en (sociale) angstklachten werd niet gevonden. De huidige studie bevestigt dat psychologische inflexibiliteit een onderliggend probleem vormt voor kinderen met angsten of kinderen die gepest worden. De gevonden verbanden bleken sterker voor angst als algemene trek dan voor sociale angst. Geslacht werd ter controle meegenomen in de analyses, maar verschillen tussen jongens en meisjes werden niet gevonden. ACT vermindert de psychologische inflexibiliteit door het versterken van de psychologische flexibiliteit. De verwachting dat de inzet van ACT de angstklachten en de gevolgen van het gepest worden bij kinderen kan verminderen wordt middels deze studie ondersteund. Verklaringen, beperkingen en relevantie worden besproken evenals suggesties voor verder onderzoek.

Effectiviteit van Preventieve Interventies op het Gezinsfunctioneren bij hoogangstige Kinderen

Het doel van dit onderzoek is inzicht geven in het effect van preventieve angstinterventies op verschillende stijlen (algeheel, functioneel, disfunctioneel) van het gezinsfunctioneren bij hoogangstige kinderen en hun ouders. De proefpersonen (N = 2494) werden gerekruteerd op basisscholen. Uiteindelijk bleven 150 respondenten over. Deze respondenten bestaan uit 70 (46.7%) jongens en 80 (53.3%) meisjes. De respondenten zijn kinderen van 8 tot 13 jaar. De gemiddelde leeftijd van de respondenten is 9.83 jaar (SD = 1.14), de jongste is 8 en de oudste is 13 jaar. De screeningsprocedure is uitgevoerd met de kindversie van de zelfrapportage vragenlijst Screen for Child Anxiety Related Emotional Disorders. Na screening werden de hoogangstige kinderen en hun ouders gerandomiseerd over de drie onderzoekscondities. Daarnaast werd aan de deelnemers gevraagd de Family Functioning Scale in te vullen. Maximaal 3 maanden na de screening vond de voormeting plaats bij kinderen en ouders, hierna vond na maximaal 6 weken de interventie plaats. Na de voormeting volgden de follow-up metingen na respectievelijk 1 en 2 jaar. Om de variabele angst te meten is gebruik gemaakt van de Screen for Child Anxiety Related Emotional Disorder (SCARED-71; Bodden, Bögels, & Muris, 2009). Om de variabele gezinsfunctioneren te meten is gebruik gemaakt van de Family Functioning Scale (FFS; Bloom, 1985). De resultaten lieten zien dat het gezinsfunctioneren bij hoogangstige kinderen en hun ouders niet verbetert na het volgen van een interventie of geen interventie. Daarnaast is geen verschil in effectiviteit gevonden tussen de kind- of oudergerichte interventie op de verschillende aspecten van het gezinsfunctioneren.

Parent and child perspectives on the nature of anxiety in children and young people with Autism Spectrum Disorders: a focus group study

Anxiety disorders are common among children and young people with Autism Spectrum Disorders (ASD). Despite growing knowledge about the prevalence, phenomenology and treatment of anxiety disorders, relatively little is understood about the nature and impact of anxiety in this group and little is known about autism-specific factors that may play a role in the increased prevalence of anxiety disorders. In this exploratory study, we report on a series of 5 focus groups with 17 parents of children and adolescents with ASD and anxiety. Across groups, parents gave strikingly similar descriptions of the triggers and behavioural signs associated with anxiety. Another consistent finding was that many parents reported that their children had great difficulty expressing their worries verbally and most showed their anxiety through changes in their behaviour. The impact of anxiety was reported to often be more substantial than the impact of ASD itself. The implications of the focus group findings are discussed in relation to existing literature.

Doll Play narratives about starting school in children of socially anxious mothers, and their relation to subsequent child school-based anxiety

Background: Child social anxiety is common, and predicts later emotional and academic impairment. Offspring of socially anxious mothers are at increased risk. It is important to establish whether individual vulnerability to disorder can be identified in young children. Method: The responses of 4.5 year-old children of mothers with social phobia (N = 62) and non-anxious mothers (N = 60) were compared, two months before school entry, using a Doll Play (DP) procedure focused on the social challenge of starting school. DP responses were examined in relation to teacher reports of anxious-depressed symptoms and social worries at the end of the child’s first school term. The role of earlier child behavioral inhibition and attachment, assessed at 14 months, was also considered. Results: Compared to children of non-anxious mothers, children of mothers with social phobia were significantly more likely to give anxiously negative responses in their school DP (OR = 2.57). In turn, negative DP predicted teacher reported anxious-depressed and social worry problems. There were no effects of infant behavioral inhibition or attachment. Conclusion: Vulnerability in young children at risk of anxiety can be identified using Doll Play narratives.

Parent-child interactions and adolescent anxiety: a systematic review

Parental behaviours have been implicated in the development and maintenance of anxiety in children and young people; however the degree to which findings apply to adolescents specifically remains unclear. We conducted a systematic review of studies examining the evidence for an association between parental behaviours and adolescent anxiety. Twenty two studies were identified. The results of this systematic review provide fairly consistent preliminary evidence for an association between anxiety and perceived parental control and anxious rearing in adolescence. The findings relating to an association between adolescent anxiety and perceived parental rejection and lack of warmth are somewhat less consistent. Methodological shortcomings in the studies mean that these results should be interpreted with caution. Future research should be conducted using observational and experimental design with adolescents from referred, clinical populations to help identify the critical parental processes and clarify the direction of effects.

The impact of a child's unexpected hospitalization upon Taiwanese parents' situational anxiety

Background. The parents of a sick child likely experience situational anxiety due to their young child being unexpectedly hospitalized. The emotional upheaval may be great enough that their anxiety inhibits them in providing positive support to their hospitalized child. Because anxiety affects psychological distress as well as behavioral distress, identifying parental distress helps parents improving their coping mechanisms. ^ Purpose. The study compared situational anxiety levels between Taiwanese fathers and mothers and focused on differences between parental anxiety levels at the beginning of the child's unplanned hospitalization and at time of discharge. The study also identified factors related to the parents' distress and use of coping mechanisms. ^ Methods. A descriptive, comparative research design was used to determine the difference between the anxiety levels of 62 Taiwanese father-mother dyads during the situational crisis of their child's unexpected hospitalization. The Mandarin version (M) of Visual Analog Scale (VAS-M), State-Trait Anxiety Inventory (STAI-M), and the Index of Parent Participation/Hospitalized Child (IPP/HC-M) were used to differentiate maternal and paternal anxiety levels and identify factors related to the parents' distress. Questionnaires were completed by parents within 24-36 hours of the child's hospital admission and within 24 hours prior to discharge. A paired t-test, two sample t-test, and linear mixed regression model were used to test and support the study hypothesis. ^ Results. The findings reveal that the mothers' anxiety levels did not significantly differ from the fathers' anxiety level when their child had a sudden admission to the hospital. In particular, parental state anxiety levels did not decrease during the child's hospital stay and subsequent discharge. Moreover, anxiety levels did not differ between parents regardless of whether the child's disease was acute or chronic. The most effective factor related to parental situational anxiety was parental perception of the severity of the child's illness. ^ Conclusions. Parental anxiety was found to be significantly related to changes in their perception of the severity of their child's illness. However, the study was not able to illustrate how parental involvement in the child's hospital care was related to parental perception of the severity of their child's illness. Future studies, using a qualitative approach to gamer more information as to what variables influence parental anxiety during a situational crisis, may provide a richer database from which to modify key variables as well as the instruments used to improve the quality of the data obtained. ^
