A multitrait-multimethod analysis of the construct validity of child anxiety disorders in a clinical sample

Relationships between Anxiety, Attention, and Reading Comprehension in Children

Many studies link anxiety in children with reading difficulties, but some facets of anxiety have been found to be positively associated with reading achievement. Attentional Control Theory offers a potential explanation for these seemingly contradictory findings, positing that anxiety can both interfere in attentional processes and enhance effort and use of compensatory processing strategies. The current study examines the relationships between anxiety, attentional control, and reading comprehension in a racially-diverse sample of 251 second-grade students, most of whom were struggling readers. Results showed that harm avoidance was positively associated with reading comprehension and physical symptoms of anxiety were negatively associated with reading comprehension. These links were attenuated when including attentional control in the model, suggesting mediation and lending support to Attentional Control Theory. Further research is needed to confirm causal mediation effects between anxiety, attentional control, and reading performance.

Differences in Parent and Child Report on the Screen for Child Anxiety-Related Emotional Disorders (SCARED): Implications for Investigations of Social Anxiety in Adolescents

Social anxiety typically emerges by adolescence and is one of the most common anxiety disorders. Many clinicians and researchers utilize the Screen for Child Anxiety Related Disorders (SCARED) to quantify anxiety symptoms, including social anxiety, throughout childhood and adolescence. The SCARED can be administered to both children and their parents, though reports from each informant tend to only moderately correlate. Here, we investigated parent-child concordance on the SCARED in a sample of adolescents (N = 360, M_age = 13.2) using a multi-trait multi-method (MTMM) model. Next, in a selected sample of the adolescents, we explored relations among child report, parent report, and latent social anxiety scores with two laboratory tasks known to elicit signs of social anxiety in the presence of unfamiliar peers: a speech task and a "Get to Know You" task. Findings reveal differences in variance of the SCARED accounted for by parent and child report. Parent report of social anxiety is a better predictor of anxiety signs elicited by a structured speech task, whereas child report of social anxiety is a better predictor of anxiety signs during the naturalistic conversation with unfamiliar peers. Moreover, while latent social anxiety scores predict both observed anxiety measures, parent report more closely resembles latent scores in relation to the speech task, whereas child report functions more similarly to latent scores in relation to the peer conversation. Thus, while latent scores relate to either observed anxiety measure, parent and child report on the SCARED each provide valuable information that differentially relate to naturalistic social anxiety-related behaviors.

Using Evaluative Criteria to Review Youth Anxiety Measures, Part II: Parent-Report

This Evidence Base Update of parent-report measures of youth anxiety symptoms is a companion piece to our update on youth self-report anxiety symptom measures (Etkin et al., 2021). We rate the psychometric properties of the parent-report measures as Adequate, Good, or Excellent using criteria developed by Hunsley and Mash (2008) and Youngstrom et al. (2017). Our review reveals that the evidence base for parent-report measures is considerably less developed compared with the evidence base for youth self-report measures. Nevertheless, several measures, the parent-report Screen for Child Anxiety-Related Emotional Disorders, Multidimensional Anxiety Scale for Children, and Spence Children's Anxiety Scale, were found to have Good to Excellent psychometric properties. We conclude our review with suggestions about which parent-report youth anxiety measures are best suited to perform different assessment functions and directions for additional research to expand and strengthen the evidence base.

Development of the Signposting Questionnaire for Autism (SQ-A): measurement comparison with the 10-item Autism Spectrum Quotient-Child and the Strengths and Difficulties Questionnaire in the UK and Latvia

Background

Recognising the signs of autism spectrum disorder (ASD) can be a challenge for frontline professionals. The use of brief parent-completed questionnaires for recording the signs of ASD in school-aged children may be an important and efficient contributor to professional insight. However, to date, such questionnaires have not been designed to be used in coordination with current standardised Diagnostic and Statistical Manual of Mental Disorders (DSM-5) diagnostic tools. Furthermore, the measurement characteristics of such questionnaires have been unexplored across countries that differ in levels of national autism service provision and cultural interpretation of the signs of ASD.

Methods

A new 14-item questionnaire (Signposting Questionnaire for Autism (SQ-A)) was developed using published DSM-5 items from a clinical interview, the Diagnostic Interview for Social Communication Disorders (DISCO). Measurement comparison was tested with the Short Autism Spectrum Quotient-Child (AQ-10) and the Strengths and Difficulties Questionnaire (SDQ). Parents of 4–11-year-old children in the UK (N = 200) and Latvia (N = 104) completed all three questionnaires. Information on clinical diagnosis provided by parents led to classification into three groups: ASD diagnosis, other conditions and no conditions. In the UK, a subsample of teachers also provided cross-informant reliability.

Results

In both countries, there was evidence of acceptable to good internal consistency for the SQ-A, with significantly higher scores for the ASD group and evidence of convergent and discriminant validity. There was also good parent-teacher reliability for the three measures. Notably, the questionnaires designed specifically to measure autism (SQ-A, AQ-10) performed more similarly to one another compared to the broader SDQ, with differences found for the ASD group. The overall pattern of responding to the three questionnaires was highly similar between countries.

Conclusions

These results indicate the potential of the 14-item SQ-A to guide frontline professionals in the recognition of the signs of autism in children, facilitating the provision of appropriate support.

A psychometric evaluation of the interRAI Child and Youth Mental Health instruments (ChYMH) anxiety scale in children with and without developmental disabilities

BACKGROUND

With 10 to 20% of Canadian children suffering with mental illness, the importance of early identification and accurate assessment systems is clear. Unfortunately, many do not receive the mental health treatment necessary and wait-times for assessment can span up to a year. In response, the interRAI suite of assessments were designed to comprehensively assess early signs of mental health impairments in children from birth to 18 years.

METHODS

This study assesses the psychometric properties of the Anxiety Scale and addresses the identification of anxiety within children diagnosed with intellectual and developmental disabilities (IDD); a commonly underrepresented sample in mental health psychometric studies. Data was collected from children aged 4-18 years in three different samples.

RESULTS

Results indicated reliable internal consistency and factor structure, as well as moderate-to-strong convergent validity.

CONCLUSIONS

We conclude that the Anxiety Scale exhibits psychometric qualities which demonstrate its clinical utility for use within a child sample, as well as in children with IDD. The findings provide support to a larger body of research which show consistent psychometric rigour of the interRAI measures.

Working From Home: An Initial Pilot Examination of Videoconferencing-Based Cognitive Behavioral Therapy for Anxious Youth Delivered to the Home Setting

Progress in evidence-based treatments for child anxiety has been hampered by limited accessibility of quality care. This study utilized a multiple baseline design to evaluate the pilot feasibility, acceptability, and preliminary efficacy of real-time, Internet-delivered, family-based cognitive-behavioral therapy for child anxiety delivered to the home setting via videoconferencing. Participants included 13 anxious youth (mean age = 9.85) with a primary/co-primary anxiety disorder diagnosis. Eleven participants (84.6%) completed treatment and all study procedures. Consistent with hypotheses, the intervention was feasible and acceptable to families (i.e., high treatment retention, high client satisfaction, strong therapeutic alliance, and low barriers to participation). Moreover, the novel videoconferencing treatment format showed preliminary efficacy: 76.9% of the intention-to-treat (ITT) sample and 90.9% of treatment completers were treatment responders (i.e., Clinical Global Impressions-Improvement Scale = 1 or 2 at posttreatment), and 69.2% of the ITT sample and 81.8% of treatment completers were diagnostic responders (as per the Anxiety Disorders Interview for Children). Gains were largely maintained at 3-month follow-up evaluation. Outcome patterns within and across subjects are discussed, as well as limitations and the need for further controlled evaluations. With continued support, videoconferencing treatment formats may serve to meaningfully broaden the reach of quality care for youth anxiety disorders.

Computerized response inhibition training for children with trichotillomania

Evidence suggests that trichotillomania is characterized by impairment in response inhibition, which is the ability to suppress pre-potent/dominant but inappropriate responses. This study sought to test the feasibility of computerized response inhibition training for children with trichotillomania. Twenty-two children were randomized to the 8-session response inhibition training (RIT; n = 12) or a waitlisted control (WLT; n = 10). Primary outcomes were assessed by an independent evaluator, using the Clinical Global Impression-Improvement (CGI-I), and the NIMH Trichotillomania Severity (NIMH-TSS) and Impairment scales (NIMH-TIS) at pre, post-training/waiting, and 1-month follow-up. Relative to the WLT group, the RIT group showed a higher response rate (55% vs. 11%) on the CGI-I and a lower level of impairment on the NIMH-TIS, at post-training. Overall symptom reductions rates on the NIMH-TSS were 34% (RIT) vs. 21% (WLT) at post-training. The RIT's therapeutic gains were maintained at 1-month follow-up, as indicated by the CGI-I responder status (= 66%), and a continuing reduction in symptom on the NIMH-TSS. This pattern of findings was also replicated by the 6 waitlisted children who received the same RIT intervention after post-waiting assessment. Results suggest that computerized RIT may be a potentially useful intervention for trichotillomania.

Manualized and Modular Behavior Therapy for a Child With Tourette’s Disorder, Inattention, and Disruptive Behavior

Persistent tic disorders (PTDs), including Tourette’s Disorder (TD), involve motor and/or vocal tics and often cause significant impairment and distress for affected individuals and families. Functional impairment is typically greater among individuals with PTDs and comorbid disorders. The current gold standard behavioral intervention for tic disorders, Comprehensive Behavioral Intervention for Tics (CBIT), has demonstrated efficacy in randomized clinical trials. Complications introduced by comorbidities, however, potentially facilitate less optimal long-term outcomes using this treatment approach. This case study describes the implementation of CBIT and subsequent modularized parent training for an 8-year-old boy diagnosed with TD who also exhibited comorbid symptoms of inattention, hyperactivity, and oppositional behavior. Emphasis is placed on delineating treatment decisions, including the sequencing of specific techniques, in accord with algorithms for complicated PTD presentations discussed in the literature.

Assessing the Construct Validity and Reliability of School Health Records Using the 'Health Dialogue Questionnaire' in the Eleventh Grade

BACKGROUND AND AIMS

The aim for this study was to assess the construct validity and reliability of the Health Dialogue Questionnaire (HDQ©) for eleventh grade in school through comparison of the HDQ© with Paediatric Quality Of Life Inventory (PedsQL™), Local monitoring of youth policy questionnaire (LUPP®), Health behaviour in Swedish school-aged children (HBSC©), Equal health (EH©) and The Swedish Survey Youth on Alcohol Consumption (SSYAC©).

METHODS

Cross-sectional samples of eleventh graders from the academic year 2009/2010 was used from the HDQ© (n = 2752), the HBSC© (n = 2090), the PedsQL™ (n = 666), the "LUPP®" questionnaires (n = 2400), EH© (n = 258), and SSYAC© (n = 1748) in the academic year 2009/2010. A comparison between HDQ© and the different proxies was done. Exploratory and confirmatory factor analyses were performed as well as a Multitrait-Multimethod Matrix (MTMM), in order to evaluate the construct validity and reliability of HDQ©.

RESULTS

An average disagreement between HDQ© and proxies with 10 percentages was found. Exploratory factor analysis of HDQ© on the 2009/2010 sample suggested a four factor solution (girls factor solution 65% of total variance explained, and in the boys' solution 59% of total variance explained). A second sample 2010/2011 of eleventh graders were used for the confirmatory solution. Almost perfectly similar four factor solutions with were found (girls 58% of total variance explained and boys 56% of the total variance explained). Using MTMM the reliability was generally high and HDQ© and showed agreeable validity.

DISCUSSION AND CONCLUSIONS

The HDQ© questionnaire is a reliable and valid instrument for measuring eleventh graders self-reported-health in school.

Analysis of the interplay between depression, anxiety, and psychological resources in adolescence using self-report measures

OBJECTIVE

Following recent literature which stresses the importance of broadening the conceptualization of mental functioning in youth, this paper aims to investigate structural relations between indicators of anxiety, depressive symptoms, and psychological resources in non-referred Italian adolescents, as captured by the Strengths and Difficulties Questionnaire (SDQ; Goodman 2001 ), the Spence Children's Anxiety Scale (SCAS; Spence 1998 ) and the Children Depression Inventory (CDI; Kovacs 1992 ).

METHODS

A hierarchical model which considers both the interplays and overlaps between these instruments is tested by means of Confirmatory Factor Analysis, in order to explore the possibility to use the three tools within a meaningful screening battery. First, validity and reliability of SDQ, SCAS, and CDI is successfully controlled thanks to three appropriate preliminary studies, an evidence not already acquired in the Italian context for the adolescent population. Then, the focal study devises and tests a model that merges indicators of the SDQ, SCAS, and CDI scales into four correlated factors, that is, Psychological Resources, Externalized behavior problems, Internalized Fear and Internalized Anxious Misery.

CONCLUSIONS

Overall, findings corroborate the combined use of SDQ, SCAS, and CDI as a screening battery for the assessment of mental functioning in youth adopting a dimensional rather than a categorical approach.

Discriminant and convergent validity of the anxiety construct in children with autism spectrum disorders

Despite reports of high anxiety in children with autism spectrum disorders (ASD), there is controversy regarding differential diagnosis of ASD symptoms and anxiety symptoms. This study examined 88 children, aged 7-11 years, with ASD referred for concerns about anxiety. A multitrait-(social anxiety, separation anxiety, overall anxiety severity, and overall ASD severity), multimethod-(diagnostic interviews, parent-, and child-based measures) analysis was conducted. Results from structural equation modeling suggest statistical discrimination between anxiety and ASD severity and convergence among differing reports of two of the anxiety subdomains (separation anxiety and overall anxiety). These findings suggest that anxiety symptoms experienced by children with ASD are separate from ASD symptom severity and may instead reflect anxiety syndromes (e.g., separation anxiety) similar to those that occur in typically developing children.

Systematic review of the properties of tools used to measure outcomes in anxiety intervention studies for children with autism spectrum disorders

BACKGROUND

Evidence about relevant outcomes is required in the evaluation of clinical interventions for children with autism spectrum disorders (ASD). However, to date, the variety of outcome measurement tools being used, and lack of knowledge about the measurement properties of some, compromise conclusions regarding the most effective interventions.

OBJECTIVES

This two-stage systematic review aimed to identify the tools used in studies evaluating interventions for anxiety for high-functioning children with ASD in middle childhood, and then to evaluate the tools for their appropriateness and measurement properties.

METHODS

Electronic databases including Medline, PsychInfo, Embase, and the Cochrane database and registers were searched for anxiety intervention studies for children with ASD in middle childhood. Articles examining the measurement properties of the tools used were then searched for using a methodological filter in PubMed, and the quality of the papers evaluated using the COSMIN checklist.

RESULTS

Ten intervention studies were identified in which six tools measuring anxiety and one of overall symptom change were used as primary outcomes. One further tool was included as it is recommended for standard use in UK children's mental health services. Sixty three articles on the properties of the tools were evaluated for the quality of evidence, and the quality of the measurement properties of each tool was summarised.

CONCLUSIONS

Overall three questionnaires were found robust in their measurement properties, the Spence Children's Anxiety Scale, its revised version - the Revised Children's Anxiety and Depression Scale, and also the Screen for Child Anxiety Related Emotional Disorders. Crucially the articles on measurement properties provided almost no evidence on responsiveness to change, nor on the validity of use of the tools for evaluation of interventions for children with ASD.

Feasibility, reproducibility, and clinical validity of the pediatric anxiety rating scale-revised for fragile X syndrome

Fragile X syndrome (FXS) is the most common inherited cause of intellectual disability and the most common known genetic cause of autism. FXS is associated with psychiatric impairments, including anxiety disorders. There is a paucity of well-developed measures to characterize anxiety in FXS. However, such scales are needed to measure therapeutic responses to interventions. The Pediatric Anxiety Rating Scale-Revised (PARS-R) was evaluated in 49 individuals with FXS. Feasibility, reproducibility, and clinical validity were assessed. High inter-rater, test-retest, and cross-site reliability were achieved. PARS-R scores were correlated with parent-report and physician ratings of anxiety, suggesting good clinical validity. Results were similar within gender and age subgroups. The PARS-R is a promising tool for measuring the efficacy of interventions targeting anxiety in FXS.

Evaluation of two single-factor models of metabolic syndrome: a confirmatory factor analysis for an adult population in Beijing

Background

Prevalence of metabolic syndrome is high and increasing in China. The causation of this disorder is, yet, to be fully understood. Several studies with confirmatory factor analysis have been performed to investigate the core of the disease in some races other than Chinese, and amongst the other studies, they have yielded a sound model fit. This study was to evaluate and compare two single-factor models of the underlying factor structure of metabolic syndrome in a Chinese population using confirmatory factor analysis.

Results

Findings showed that in a Chinese sample of 7,472 individuals, Model 1 (with waist circumference, triglycerides/HDL-C ratio, fasting plasma glucose and mean artery pressure) yielded good level of fitness (SRMR < 0.08, CFI > 0.96 and RMSEA < 0.10) in men and women of all age groups; and Model 2 (with waist circumference, triglycerides, fasting plasma glucose and systolic blood pressure) fitted well in men aged 18–34 and over 60 and in all women, except in men of 35–59 (RMSEA = 0.142). In comparison, Model 2 were shown to be better fit (with relative larger GFI and smaller AIC, BIC, CAIC, and EVIC) in women of all age groups and in men of 18–34 and over 60 years old; Model 1 had a better fit in men between 35 and 59.

Conclusions

This study suggests that the single-factor model of metabolic syndrome with waist circumference, triglycerides, fasting plasma glucose and systolic blood pressure are plausible in women of all age groups and young and senior men in Beijing. The model with waist circumference, triglycerides/HDL-C ratio, fasting plasma glucose and mean artery pressure fits middle-aged men.

Associations between household and neighborhood income and anxiety symptoms in young adolescents

BACKGROUND

A better understanding of the role of both family- and neighborhood-level socioeconomic characteristics in the development of anxiety disorders is important for identifying salient target populations for intervention efforts. Little research has examined the question of whether associations between anxiety and socioeconomic status (SES) differ depending upon the level at which SES is measured or way in which anxiety manifests. We studied associations between both household- and neighborhood-level income and four different manifestations of anxiety in a community sample of young adolescents.

METHODS

We conducted a cross-sectional analysis of data on 498 subjects aged 11-13 from a cohort study of Seattle-area middle school students. Generalized estimating equations were used to examine the association between both annual household income and neighborhood median income and each of four anxiety subscale scores from the multidimensional anxiety scale for children (MASC): physical symptoms, harm avoidance, social anxiety, and separation/panic anxiety.

RESULTS

A negative association was found between household income and scores on two of the four MASC subscales--physical symptoms and separation/panic anxiety. In contrast, at equivalent levels of household income, adolescents living in higher income neighborhoods reported higher physical and harm avoidance symptom scores.

CONCLUSION

The role that SES plays in the development of childhood anxiety appears to be complex and to differ depending on the specific type of anxiety that is manifest and whether income is evaluated at the household or neighborhood level.

Mean diffusivity in the amygdala correlates with anxiety in pediatric TBI

Traumatic brain injury (TBI) and orthopedic injury (OI) patients are prone to anxiety and mood disorders. In the present study, we integrated anatomical and diffusion tensor neuroimaging to investigate structural properties of the amygdala and hippocampus, gray matter regions implicated in anxiety and mood disorders. Children and adolescents were evaluated during the late sub-acute phase of recovery following trauma resulting from either moderate to severe TBI or OI. Mean diffusivity (MD) of the amygdala and hippocampus was elevated following TBI. An interaction of hemisphere, structure, and group revealed that MD of the right amygdala was elevated in females with TBI. Self-reported anxiety scores were not related to either volume or microstructure of the hippocampus, or to volume or fractional anisotropy of the amygdala. Left amygdala MD in the TBI group accounted for 17.5% of variance in anxiety scores. Anxiety symptoms may be mediated by different mechanisms in patients with TBI or OI.
