Childhood Language Disorder and Social Anxiety in Early Adulthood

Artificial intelligence impacts in education and pediatric mental health

PURPOSE OF REVIEW

Increased accessibility of artificial intelligence to children has raised concerns regarding its effects on education and student mental health. Pediatricians should continue to be informed about the effects of artificial intelligence in their patients' daily lives, as artificial intelligence is becoming increasingly present.

RECENT FINDINGS

The use of artificial intelligence to create personalized study material illustrates a benefit of incorporating this technology into education. However, an overreliance on artificial intelligence could decrease students' problem-solving skills and increase plagiarism. Novel uses of artificial intelligence have also raised concerns regarding mental health. Deepfake technology, which utilizes artificial intelligence to create images, videos, and/or audio that appears real but is fabricated, can be viewed online by children, which could have negative mental health implications.

SUMMARY

Although artificial intelligence has the potential to revolutionize education at all levels, its use as an enhancement, not replacement, to current educational strategies is imperative. Both parents and students need to understand the limitations of artificial intelligence in education, and simultaneously prioritize developing the necessary cognitive skills strengthened throughout education. Pediatricians and parents should also be aware of the potentially dangerous material generated by artificial intelligence that can negatively impact children's mental health.

Evaluating the association between developmental language disorder and depressive symptoms in preschool children

This study aims to investigate the association between developmental language disorder (DLD) and depressive symptoms in preschool-aged children, building upon previous research that has demonstrated emotional difficulties in children with DLD. Forty-one children with DLD or children at risk for DLD (DLD group) and 41 children with typical language development (TLD) were included in this study. Language development was evaluated using the TEDIL test which is a Turkish adaptation of the Test of Early Language Development-3. Auto acoustic Emissions Testing and Immittance-Metric Assessment were used to exclude children with hearing impairment. Developmental delays were excluded by Denver Developmental Screening Test II. Mothers filled out the Sociodemographic Data Form and the Child Depressive Symptoms Assessment Scale. The results demonstrate that children in DLD group scored significantly higher on the Child Depressive Symptoms Assessment Scale, manifesting increased levels of aggression, separation anxiety, impulsivity, hyperactivity, and encountering greater social adaptation difficulties and deterioration in cognitive processes than TLD. Multivariate regression analysis suggests that increased impulsivity and hyperactivity, alongside social and cognitive challenges, are predictors of DLD. The study concludes that depressive symptoms are more prevalent in children in DLD group than in their typically developing counterparts. These findings underscore the necessity for targeted psychiatric and pedagogical interventions, as well as individualized educational programs that cater to the socio-emotional and cognitive needs of children with DLD.

Language skills and interpersonal trust in adolescents with and without mental illness

PURPOSE

The primary aim was to compare adolescents with mental illness and non-clinical adolescents on vocabulary, social problem-solving, trust in parents, attachment and mentalisation. A secondary aim was to investigate whether adolescents' language skills were associated with trust in parents.

METHOD

Seventy-eight adolescents (16-18 years) participated in this cross-sectional quantitative study: a clinical sample (n = 28, M = 16.7 years, 19F) recruited from a mental health service and a non-clinical sample (n = 50, M = 17.0 years, 28F). Standardised language measures and self-report measures of trust in parents; communication quality; attachment; and mentalisation were used. Primary and secondary aims were addressed through independent samples t-tests and Pearson's correlation analyses, respectively.

RESULT

Adolescents experiencing mental illness reported significantly poorer vocabulary, less trust in mother/father, greater attachment anxiety/avoidance, and poorer reflective functioning, than non-clinical adolescents. Expressive vocabulary of clinical (but not non-clinical) adolescents significantly negatively correlated with trust in mother (but not father).

CONCLUSION

Results highlight a role for speech-language pathologists (SLPs) in supporting communication needs of adolescents with mental illness. SLPs should consider trust by: i) understanding adolescents with mental illness may have difficulty trusting them potentially impacting therapeutic engagement; and ii) delivering services in ways that might build trust, such as involving adolescents in treatment planning.

The Engage with Developmental Language Disorder (E-DLD) project: Cohort profile

BACKGROUND

Public awareness of Developmental Language Disorder (DLD) is lower than other neurodevelopmental disorders, despite its high prevalence of 7.6%. This lower awareness means recruitment for DLD research studies is difficult. DLD is both underfunded and under-researched, resulting in relatively limited research investigating individuals with DLD. Engage with Developmental Language Disorder (E-DLD) is a response to these considerations. E-DLD is the first international participant database of those affected by DLD. Parents of children with DLD under 16 and young people and adults over 16 from anywhere in the world can sign up to be a part of the E-DLD.

AIMS

This paper aims to describe the families of children with DLD and adults with DLD in the database thus far.

METHODS & PROCEDURES

E-DLD members sign up via our website, reporting demographic characteristics as part of this procedure. We request all E-DLD members subsequently fill in a yearly survey. The content of the yearly survey changes dependent on the age of the child, while the yearly survey for adults remains consistent. We measure a wide range of domains, such as speech and language therapy (SLT) support, school support, socialisation skills, and early developmental milestones for our youngest members, and health care support and mental well-being measurements for our adults. We also collect parent and self-reported reflections on strengths and challenges for the person with DLD using open-ended questions and the Strengths and Difficulties Questionnaire.

OUTCOMES & RESULTS

The database currently consists of 196 parents of children with DLD and 20 individuals over the age of 16 with DLD or suspected DLD across a range of socioeconomic status (SES) backgrounds. Our initial results confirm that E-DLD members meet the linguistic profile of DLD in relation to self- or parent-rated language difficulties. Both children and adults show increased rates of psychosocial difficulties compared to established norms, consistent with past research on clinical samples of people with DLD.

CONCLUSIONS & IMPLICATIONS

The findings indicate that a participant database for DLD research is feasible and useful. The rates of emotional, behavioural and sleep difficulties among the child probands are higher than reported rates amongst typically developing children. Initial data indicate that adults with DLD have poorer well-being than their peers. The E-DLD is a useful collection of data on those affected by DLD and is a promising method for connecting people with DLD with academic researchers.

WHAT THIS PAPER ADDS

What is already known on this subject Developmental Language Disorder (DLD) is characterised by expressive and/or receptive language difficulties in the absence of another biomedical condition that could explain these difficulties. It is critically under-researched and underfunded. As such, there is a lack of public awareness and difficulty recruiting sufficient sample sizes for DLD research studies. What this paper adds to existing knowledge Engage with Developmental Language Disorder (E-DLD) is the first international participant database of individuals with DLD. This paper provides a preliminary report on the profile of linguistic and psychosocial skills among the individuals on the database, adding to current understanding of DLD across age groups. What are the potential or actual clinical implications of this work? Our aim is that the E-DLD will provide much-needed facilitation of research into DLD. E-DLD will enable those with DLD and their families more readily to shape research agendas and to participate in studies that interest them. Families may be recruited into research that could directly translate to better clinical treatment of DLD. We also believe that the E-DLD yearly survey holds potential to provide key information on the development and longitudinal experience of children and adults with DLD.

Systematic Review and Meta-Analysis of Screening Tools for Language Disorder

Language disorder is one of the most prevalent developmental disorders and is associated with long-term sequelae. However, routine screening is still controversial and is not universally part of early childhood health surveillance. Evidence concerning the detection accuracy, benefits, and harms of screening for language disorders remains inadequate, as shown in a previous review. In October 2020, a systematic review was conducted to investigate the accuracy of available screening tools and the potential sources of variability. A literature search was conducted using CINAHL Plus, ComDisCome, PsycInfo, PsycArticles, ERIC, PubMed, Web of Science, and Scopus. Studies describing, developing, or validating screening tools for language disorder under the age of 6 were included. QUADAS-2 was used to evaluate risk of bias in individual studies. Meta-analyses were performed on the reported accuracy of the screening tools examined. The performance of the screening tools was explored by plotting hierarchical summary receiver operating characteristic (HSROC) curves. The effects of the proxy used in defining language disorders, the test administrators, the screening-diagnosis interval and age of screening on screening accuracy were investigated by meta-regression. Of the 2,366 articles located, 47 studies involving 67 screening tools were included. About one-third of the tests (35.4%) achieved at least fair accuracy, while only a small proportion (13.8%) achieved good accuracy. HSROC curves revealed a remarkable variation in sensitivity and specificity for the three major types of screening, which used the child's actual language ability, clinical markers, and both as the proxy, respectively. None of these three types of screening tools achieved good accuracy. Meta-regression showed that tools using the child's actual language as the proxy demonstrated better sensitivity than that of clinical markers. Tools using long screening-diagnosis intervals had a lower sensitivity than those using short screening-diagnosis intervals. Parent report showed a level of accuracy comparable to that of those administered by trained examiners. Screening tools used under and above 4yo appeared to have similar sensitivity and specificity. In conclusion, there are still gaps between the available screening tools for language disorders and the adoption of these tools in population screening. Future tool development can focus on maximizing accuracy and identifying metrics that are sensitive to the dynamic nature of language development.

"So, I told him to look for friends!" Barriers and protecting factors that may facilitate inclusion for children with Language Disorder in everyday social settings: Cross-cultural qualitative interviews with parents

PURPOSE

Although researchers have explored parental perspectives on childhood speech and language disorders, this work has mostly been conducted in English-speaking countries. Little is known about parental experiences across countries. Participation in the COST Action IS1406 'Enhancing children's oral language skills across Europe and beyond' provided an opportunity to conduct cross-cultural qualitative interviews. The aims were to explore how parents construe inclusion and/or exclusion of their child and how parents involve themselves in order to facilitate inclusion.

METHOD

Parents from nine countries and with a child who had received services for speech-language disorder participated in semi-structured qualitative interviews. We used thematic analysis to analyze the data.

RESULTS

Two overarching themes were identified: 'Language disabilities led to social exclusion' and 'Promoting pathways to social inclusion'. Two subthemes were identified Interpersonal relationships are important and Deliberate proactiveness as stepping stones for social inclusion.

CONCLUSIONS

Across countries, parents report that their children's hidden disability causes misunderstandings that can lead to social exclusion and that they are important advocates for their children. It is important that the voices and experiences of parents of children with developmental disabilities are understood and acknowledged. Parents' recommendations about how to support social inclusion need to be addressed at all levels of society.

Beyond the Senses: How Self-Directed Speech and Word Meaning Structure Impact Executive Functioning and Theory of Mind in Individuals With Hearing and Language Problems

Many individuals with developmental language disorder (DLD) and individuals who are deaf or hard of hearing (D/HH) have social–emotional problems, such as social difficulties, and show signs of aggression, depression, and anxiety. These problems can be partly associated with their executive functions (EFs) and theory of mind (ToM). The difficulties of both groups in EF and ToM may in turn be related to self-directed speech (i.e., overt or covert speech that is directed at the self). Self-directed speech is thought to allow for the construction of non-sensory representations (i.e., representations that do not coincide with direct observation). Such non-sensory representations allow individuals to overcome the limits set upon them by the senses. This ability is constrained by the development of word meaning structure (i.e., the way words are understood). We argue that the greater ability to construct non-sensory representations may result in more enhanced forms of EF and ToM. We conclude that difficulties in EF, ToM, and social–emotional functioning in those with hearing and language problems may be accounted for in terms of word meaning impairments. We propose that word meaning structure and self-directed speech should be considered in assigning EF and ToM treatments to individuals with DLD and those who are D/HH.

Tense Marking in the Kindergarten Population: Testing the Bimodal Distribution Hypothesis

Purpose The purpose of this study was to explore whether evidence for a bimodal distribution of tense marking, previously documented in clinically referred samples, exists in a population-based sample of kindergarten children from a rural county in Tennessee. Method A measure of tense marking, the Test of Early Grammatical Impairment (TEGI) Screening Test, was individually administered to consented kindergarten students (N = 153) across three elementary schools in a single school district. The consented children constituted 73% of kindergartners in the district. Cluster analysis was used to evaluate the number and composition of latent classes that best fit the distribution of the TEGI Screening Test scores. Results Analysis of the scores revealed a distribution that deviated significantly from normality. Cluster analyses (Ward's, k-means, single linkage) revealed a two-cluster solution as the best fitting model. The very large effect-size difference in mean TEGI Screening Test score between the two clusters (d = 4.77) provides validation of an identifiable boundary delineating typical from atypical tense marking in this sample of kindergartners. The difference in tense marking across the two clusters was not attributable to child chronological age. The percentage of the sample comprising the low-performing cluster aligns with specific language impairment and developmental language disorder prevalence estimates. Conclusion Additional demonstrations of a bimodal distribution of tense marking in future studies with carefully defined samples could strengthen the clinical marker evidence and utility of this linguistic feature.

What is the nature of peer interactions in children with language disorders? A qualitative study of parent and practitioner views

Background and aims

Children with Language Disorders (LDs) can exhibit increased levels of social withdrawal, aggression and problems managing social conflicts. The reasons underlying this pattern of social interaction profiles remain unclear. This qualitative study aimed to document the nature of social interactions between children with LDs and their peers, and to evaluate explanations for their social behaviour, as understood by parents and practitioners.

Methods

This study focused on children with LDs who spend school hours with other children with LDs. Three parent focus groups (n = 8) and three practitioner focus groups (n = 10) were conducted with parents of children aged 4-12 attending specialist language schools and practitioners working at these schools. This was a mixed clinical sample. All children of participating parents had LD as their primary area of need, which was the reason they required specialist schooling. Focus groups were conducted across two specialist schools in the UK between March and June 2018.

Results

An inductive reflective thematic analysis of the data identified three themes; social knowledge, coping strategies, and emotional competence. Parents and school staff reported that children with LDs experience difficulties managing peer interactions due to a combination of challenges including difficulties with understanding and regulating emotions, and difficulties understanding social situations. Some of the children with LDs were described as having developed strategies to cope with their challenges, for example imposing structure on their social interactions to manage uncertainty, which has implications for their social interactions with peers.

Conclusions

Children with LDs have difficulties understanding emotions, difficulties understanding their peer's intentions and difficulties resolving conflict situations independently according to their parents and practitioners working with these children. Participants proposed a novel explanation that social withdrawal may be used adaptively by children with LDs to process information. This study demonstrates the complexity of the relationship between Language Disorders and peer interaction profiles.Implications: Suggestions are offered regarding future research directions, such as investigating the specific contribution language skills make to children's emotion understanding, to better understand the reasons for peer interaction difficulties in children with Language Disorders.

Pharmacotherapy of Traumatic Childhood Aphasia: Beneficial Effects of Donepezil Alone and Combined With Intensive Naming Therapy

At present, language therapy is the only available treatment for childhood aphasia (CA). Studying new interventions to augment and hasten the benefits provided by language therapy in children is strongly needed. CA frequently emerges as a consequence of traumatic brain injury and, as in the case of adults, it may be associated with dysfunctional activity of neurotransmitter systems. The use of cognitive-enhancing drugs, alone or combined with aphasia therapy, promotes improvement of language deficits in aphasic adults. In this study we report the case of a 9-year-old right-handed girl, subject P, who had chronic anomic aphasia associated with traumatic lesions in the left temporal-parietal cortex. We performed a single-subject, open-label study encompassing administration of the cholinergic agent donepezil (DP) alone during 12 weeks, followed by a combination of DP and intensive naming therapy (INT) for 2 weeks and thereafter by a continued treatment of DP alone during 12 weeks, a 4-week washout period, and another 2 weeks of INT. Four comprehensive language and neuropsychological evaluations were performed at different timepoints along the study, and multiple naming evaluations were performed after each INT in order to assess performance in treated and untreated words. Structural magnetic resonance imaging (MRI) was performed at baseline. MRI revealed two focal lesions in the left hemisphere, one large involving the posterior inferior and middle temporal gyri and another comprising the angular gyrus. Overall, baseline evaluation disclosed marked impairment in naming with mild-to-moderate compromise of spontaneous speech, repetition, and auditory comprehension. Executive and attention functions were also affected, but memory, visuoconstructive, and visuoperceptive functions were preserved. Treatment with DP alone significantly improved spontaneous speech, auditory comprehension, repetition, and picture naming, in addition to processing speed, selective, and sustained attention. Combined DP-INT further improved naming. After washout of both interventions, most of these beneficial changes remained. Importantly, DP produced no side effects and subject P attained the necessary level of language competence to return to regular schooling. In conclusion, the use of DP alone and in combination with INT improved language function and related cognitive posttraumatic deficits in a child with acquired aphasia. Further studies in larger samples are warranted.

Training community health nurses to measure parent-child interaction: a mixed-methods study

BACKGROUND

This study aims to determine whether the Parental Responsiveness Rating Scale (PaRRiS) completed at child age 24-30 months can be used by community child health nurses (CCHNs) to reliably measure the quality of parent-child interactions in practice.

METHODS

A mixed-methods design was used involving CCHNs working in public health settings. Five CCHNs recruited from the North-East of England were trained to use PaRRiS. Thirty parent-child dyads attending their routine 24-30-month check were observed. Nurses rated parent-child dyads during 5 min of free-play using PaRRiS. The free-play sessions were video recorded and rated blind by the first author to the nurse observation. Semi-structured phone interviews were conducted with the five CCHNs once observations of parent-child interactions were complete. Interviews were audio-recorded, transcribed, anonymized and thematically analyzed.

RESULTS

Two-thirds of participating parents were mothers. Half the families (15/30) were from the 10% most deprived areas based on the English Index of Multiple Deprivation. The average PaRRiS score was 3.03 [standard deviation (SD) = 0.8; all ratings were <5.0]. Reliability between the first author ('gold standard') and CCHNs was excellent [Intra-class correlation coefficient (ICC): 0.85; 95% confidence interval (CI): 0.67-0.93]. CCHNs found PaRRiS aligned well with current practice and was acceptable to parents. There was no evidence of a relationship between social disadvantage and PaRRiS scores.

CONCLUSIONS

With further development and evaluation work, PaRRiS could potentially be incorporated into existing universal health services to provide child health nurses with an additional tool for identifying families most likely to be in need of parent-child interaction interventions.

Clinical Lessons From Studies of Children With Specific Language Impairment

Purpose

This clinical focus article addresses a current debate contrasting the long-standing label of “specific language impairment” (SLI) with a recent alternative, “developmental language disorders” (DLDs); the criteria for SLI yields a subset of children defined as DLD. Recent social media advocacy for DLD asserts that the two categories of children are clinically equivalent, and therefore, DLD can be used as a label for which SLI criteria would hold. Coupled with DLD advocacy is the assumption that research on SLI has not yielded clinically relevant outcomes. This clinical focus article challenges those assumptions. The clinical focus article is framed as parallels between precision medicine and evidence-based practice. The purposes of this clinical focus article are as follows: (a) revisit the legacy of research on SLI; (b) describe language development in children with SLI into adulthood; (c) address widespread but erroneous assumptions about relationships between speech impairments and language impairments, and relationships between nonverbal IQ and language impairments; (d) briefly review evidence for causal pathways; and (e) present clinical lessons from research on children with SLI.

Method

Narrative review is the method used in the study.

Conclusions

The purposes of the clinical focus article were met by reviews, commentary, and supporting arguments in each section. The conclusions are that the research and clinical category of SLI is needed for accurate and precise clinical practice, including diagnosis, prognosis, clinical goals, sequencing of tasks for success, and consideration of language disorders in the context of a broad thicket of related consequences.

The Interplay Between Theory of Mind and Social Emotional Functioning in Adolescents With Communication and Language Problems

Adolescents with developmental language disorders (DLDs) and adolescents who are deaf or hard of hearing (D/HH) are at greater risk of social emotional problems. These problems may not only be attributed to communication and language problems but, at least in part, to Theory of Mind (ToM) deficits as well. In this mini review, an overview is provided of studies on social emotional functioning and ToM performance in adolescents with DLD and D/HH adolescents. A possible interplay between social emotional functioning and Theory of Mind is discussed. There is empirical evidence for social emotional problems and ToM problems in both adolescents with DLD and D/HH. We hypothesized that language deficits as seen in adolescents with DLD and impoverished exposure to language and communication, as seen in adolescents who are D/HH can explain differences in social emotional functioning and ToM performance. The present mini review provides a possible framework for the relation between ToM and social emotional functioning in adolescents with communication and language problems, which is mediated by their limited linguistic ability or restricted language exposure and gives suggestions for future research.

Language difficulties and internalizing problems: Bidirectional associations from 18 months to 8 years among boys and girls

Studies have shown that early language difficulties are associated with later internalizing problems. Less is known about the nature of the association: the bidirectional relationship over time, the role of different types of language difficulties, and gender differences. The present study examined bidirectional longitudinal associations between parent-rated language difficulties and internalizing problems in a four-wave cross-lagged model from 18 months to 8 years. Data from the Norwegian Mother and Child Cohort Study were used (N = 114,000). Gender-specific dichotomized language variables were created, and associations were investigated uniquely for boys and girls. Logistic regression analyses showed that all cross-lagged associations from 18 months to 5 years were significant for girls (odds ratios [ORs] = 1.48-1.94). For boys, only internalizing problems at 3 years predicted change in language difficulties (OR = 2.33). From 5 to 8 years, the cross-lagged associations between semantic language difficulties and internalizing problems were significant and strong for girls (ORs = 1.92-2.97) and nonsignificant for boys. The results suggest that the associations between language difficulties and internalizing problems are bidirectional from an early age, and that girls are especially vulnerable for developing co-occurring language difficulties and internalizing problems during the years of transition to school.

Language disorder and retrospectively reported sexual abuse of girls: severity and disclosure

BACKGROUND

Despite emerging evidence for an association between communication disorders and maltreatment, little research has examined sexual abuse characteristics or disclosure experiences among individuals with language disorder (LD). Given that communication difficulties may constitute a barrier to disclosure, the disclosure experiences among individuals with and without communication difficulties may also differ.

METHODS

Five-year-old children identified with a language and/or speech disorder from a nonclinical community sample and a control group were followed to adulthood in a prospective longitudinal study. At age 31, participants completed a behaviorally specific questionnaire on experiences of sexual abuse and questionnaires on disclosure experiences and social reactions to disclosure. Due to low endorsement of sexual victimization among male participants and low sample size, results are reported for women only and exclude nine participants with speech disorder without LD. Participation rates were 28 of 40 in the LD cohort and 45 of 51 controls. Sexual victimization severity was defined using an index combining five indicators (duration, invasiveness, relationship to perpetrator, coercive tactics used, and number of perpetrators). Subthreshold sexual victimization was defined as a single, noncontact incident with a perpetrator unknown to the child; experiences with greater severity were classified as child sexual abuse.

RESULTS

Among women who reported sexual victimization by age 18, invasiveness and overall severity were greater in the LD cohort than in the control cohort. Women in the LD cohort (43%) were more likely than controls (16%) to report child sexual abuse, excluding subthreshold experiences. There were no differences between cohorts in probability of disclosure, latency to disclosure, or social reactions.

CONCLUSIONS

Women with a history of child LD in a nonclinical sample reported substantial child sexual abuse experiences. Implications for understanding associations between LD and mental health and for prevention and early intervention are discussed.

Change in receptive vocabulary from childhood to adulthood: associated mental health, education and employment outcomes

BACKGROUND

Population-based studies have found that early language delays are associated with poorer long-term outcomes in adolescence and adulthood. Few studies have explored the influence of change in language ability over time on adult outcomes.

AIM

To examine the educational, vocational and mental health outcomes for adults accounting for different vocabulary developmental profiles over a 16-year period.

METHODS & PROCEDURES

A total of 1914 participants of the Mater-University of Queensland Study of Pregnancy (MUSP) were categorized into four groups based on their vocabulary skills at 5 and 21 years: (1) persistently good (n = 1679), (2) persistently poor (n = 33), (3) improved (n = 160), and (4) deteriorated (n = 42). The associations between vocabulary group and educational, vocational, and mental health outcomes at 21 years were investigated.

OUTCOMES & RESULTS

Adults with deteriorated and persistently poor vocabulary skills were less likely to have completed secondary school; with the improved, deteriorated and persistently poor groups being less likely to be engaged in education, employment or training at the 21-year follow-up, compared with the persistently good group. Adults with deteriorated performance were at an increased risk of affective disorders, as well as substance and alcohol abuse/misuse.

CONCLUSIONS & IMPLICATIONS

These findings provide evidence that impaired vocabulary skills in adulthood, regardless of whether the deficit was acquired early or later, are associated with adverse outcomes. Clinicians and educators need to be aware of these adversities and ensure they are supporting children and adolescents in whom language difficulties exist or emerge so as to prevent poor long-term outcomes from occurring.

Épidémiologie des troubles dépressifs et anxieux chez les enfants et les adolescents québécois

L’épidémiologie de la santé mentale des enfants et des adolescents est une discipline relativement récente et souvent méconnue, notamment au Québec. Certains travaux ont cependant permis d’estimer la prévalence des troubles mentaux les plus fréquents chez les jeunes, tels que les troubles anxieux et dépressifs, ainsi que les caractéristiques individuelles, familiales et socioéconomiques qui y sont associées. Cet article poursuit deux objectifs : présenter une recension des principaux résultats de recherche en épidémiologie pédopsychiatrique au Québec et mettre en évidence l’apport de ces résultats pour la santé publique. Afin d’atteindre ces objectifs, cet article présente les résultats de recherche en lien avec trois thématiques : 1) la mesure et l’identification des troubles anxieux et dépressifs chez les enfants et les adolescents ; 2) la prévalence de ces troubles et la comorbidité ; 3) les variables associées aux troubles anxieux et dépressifs identifiées dans les études épidémiologiques. Les auteurs souligneront les implications futures de ces résultats à travers les politiques québécoises dans le domaine de la santé publique.
