Internalizing correlates of dyslexia

In emotion and reading motivation, children with a diagnosis of dyslexia are not just the end of a continuum

Children with dyslexia (CwD) often report poor psychological well-being. We examined (i) whether anxiety, self-concept and reading motivation in CwD differed from those of typically developing children (TDC; case-control design, Study 1a) and (ii) whether these differences mirrored the linear relationships that these variables present with reading ability in the TDC group (dimensional approach, Study 1b). In Study 1a, 34 CwD were compared with 191 TDC in grades 4-8 on anxiety, self-concept, reading motivation and reading strategy using self-reports (controlling for sex, intelligence and math ability scores). In Study 1b, the differences that emerged in Study 1a were compared with the results obtained from a simulation procedure that generated dyslexia observations under the assumptions of a dimensional hypothesis. The CwD group presented small-to-moderate difficulties, which partially mirrored the predictions in the TDC group. However, violations of predictions based on the population without dyslexia were found for reading self-concept, social anxiety and reading competitiveness. In sum, children's diagnoses affect their self-perception as readers and social anxiety in a way that cannot be inferred from linear relationships. CwD need support to preserve an adequate image of themselves as readers and cope with social anxiety.

Dyslexia Articles Unboxed: Analyzing Their Readability Level

OBJECTIVE

Dyslexia is characterized by difficulties with fluent word recognition, decoding, or spelling, and it has been linked to family history. Given the impact of dyslexia on broad academic activities and well-being, ensuring that information about dyslexia is accessible to affected children and their families is vital. This study aims to assess the readability levels of dyslexia-related websites, with the hypothesis that such websites should be written at an appropriate readability level to accommodate those who may also have reading challenges.

METHODS

This study analyzes the readability of 50 web articles on dyslexia using 6 readability formulas: Flesch-Kincaid Reading Ease, Flesch-Kincaid Grade Level, Gunning Fog Score, Simple Measure of Gobbledygook (SMOG) Index, Coleman Liau Index, and Automated Readability Index. The search term "What is dyslexia" was used on Google. Each article was analyzed using the online calculation website WebFX. The readability goal for these websites was set at fifth grade, a level recommended for patients with reading challenges.

RESULTS

The study found that among the 50 websites, the lowest median readability score was 11.8 (corresponding to a 12th-grade level) on the SMOG Index, while the highest scores were 15.5 on both the Gunning Fog Score and the Coleman Liau Index (indicative of college-level readability). Almost none of the websites had scores below a fifth-grade level.

CONCLUSION

Most websites related to dyslexia are too complex. Tools such as readability metrics and sentence restructuring by AI can help make the information more accessible and understandable to the stakeholders.

Mental health among children with and without reading difficulties

This study explored the relationship between mental health, i.e., depression and anxiety, and reading difficulties (RD) in Chinese elementary school children. Participants were 1535 grades 3, 4, and 5 students from three elementary schools in Xi'an, China. Children with and without RD were compared to their depression and anxiety. Additionally, children's self-ratings, parents' ratings, and teachers' ratings of depression and anxiety were compared to better understand mental health issues of Chinese children with RD. The findings showed that Chinese children with RD experienced more depression but not anxiety compared to their typically developing peers across all three grade levels. Reports from all three informants consistently reflected that children with RD experienced more depression. However, some inconsistencies were found between self-reported levels of depression and anxiety and the observations made by parents and teachers. Children reported experiencing more depression than their parents and teachers observed but less anxiety than their parents reported. This study emphasizes the importance of understanding the links between RD and mental health and the need for appropriate intervention programs to help children with RD cope with the mental health challenges.

Internalizing problems in individuals with reading, mathematics and unspecified learning difficulties: a systematic review and meta-analysis

We conducted a systematic review and meta-analysis to examine if individuals with reading difficulties (RD), mathematics difficulties (MD), or unspecified learning difficulties (ULD) experience internalizing problems (i.e., anxiety, depression, somatic complaints, and social withdrawal) to the same extent, and if the effect sizes are influenced by moderators (age, internalizing problems type, anxiety type, rater type, selection criteria, and attention control). We reviewed 2,806 studies published in English between January 2000 and April 2023. Our final sample consisted of 96 studies that reported effect sizes or data to calculate them (a total of 120 unique samples, 83,260 participants, age range = 7.3 - 34.8 years). Risk of bias and sensitivity were assessed. A random-effects model analysis revealed a significant and moderate overall effect size (Hedge's g = -.54), indicating that individuals with RD, MD or ULD experience more internalizing problems than their chronological-age (CA) controls. Follow-up analyses showed that neither learning difficulties type nor age of participants were significant moderators, but selection criteria (diagnosis versus screening) and internalizing problems type were. These findings suggest that individuals with RD do not differ from those with MD or ULD in internalizing problems, and all fare poorly compared to CA controls.

Leveraging brain science for impactful advocacy and policymaking: The synergistic partnership between developmental cognitive neuroscientists and a parent-led grassroots movement to drive dyslexia prevention policy and legislation

Reading proficiency is crucial for academic, vocational, and economic success and has been closely linked to health outcomes. Unfortunately, in the United States, a concerning 63% of fourth-grade children are reading below grade level, with approximately 7%-10% exhibiting a disability in word reading, developmental dyslexia. Research in developmental cognitive neuroscience indicates that individuals with dyslexia show functional and structural brain alterations in regions processing reading and reading-related information, with some of these differences emerging as early as preschool and even infancy. This suggests that some children start schooling with less optimal brain architecture for learning to read, emphasizing the need for preventative education practices. This article reviews educational policies impacting children with dyslexia and highlights a decentralized parent-led grassroots movement, Decoding Dyslexia, which centers the voices of those directly impacted by dyslexia. It utilizes civic engagement practices, advocacy and lobbying on local, federal, and social media platforms, and strong partnerships with scientists to drive systems-level change in educational practices, leading to dyslexia prevention legislation across the U.S. The ongoing partnership continues to address the profound gaps between scientific findings and policymaking to drive systems-level change for contemporary challenges in educational practices within a learning disabilities framework.

Academic Achievement and Satisfaction Among University Students With Specific Learning Disabilities: The Roles of Soft Skills and Study-Related Factors

Understanding the individual qualities sustaining students with and without specific learning disabilities (SLDs) is key to supporting their academic achievement and well-being. In this study, we investigated the differences between students with and without SLDs in terms of intraindividual factors (soft skills and study-related factors), academic and nonacademic outcomes (achievement, academic and life satisfaction), and the relationships between such intraindividual factors and the three outcomes. A total of 318 students (79 males; Mage = 22.7; SD = 3.56; age range = 19-45 years; 147 with SLDs) completed self-reported questionnaires and a measure of fluid intelligence. The results showed that students with SLDs reported higher creativity but lower academic self-efficacy, study resilience, and academic achievement, with small-to-medium effect sizes. In both groups, achievement significantly positively related to academic self-efficacy and negatively to creativity. Life satisfaction was positively related to study resilience; and academic satisfaction was related to critical thinking, curiosity, and academic self-efficacy. Nurturing such intraindividual factors can benefit students with and without SLDs.

Conceptions and Misconceptions: What Do School-Based Speech-Language Pathologists Think About Dyslexia?

PURPOSE

The purpose of this exploratory study was to evaluate speech-language pathologists' (SLPs') conceptions and misconceptions about dyslexia.

METHOD

Participants were 86 school-based SLPs. They completed an online survey on which they rated their agreement and disagreement with true and false statements related to the scientific evidence about the nature of dyslexia and interventions for dyslexia, as well as common misconceptions about dyslexia.

RESULTS

There was considerable variability among SLPs' agreement and disagreement with the statements. Critically, despite abundant contrary evidence in the literature, many SLPs believe that dyslexia involves a visual processing deficit.

CONCLUSIONS

These findings suggest that many school-based SLPs hold misconceptions about dyslexia, especially those related to dyslexia being a visual disorder. The identified misconceptions may contribute to some SLPs' reluctance to incorporate reading and prereading skills into speech-language assessment and intervention. SLPs need greater knowledge of dyslexia to provide more effective evaluations and intervention services.

Compounding Effects of Domain-General Cognitive Weaknesses and Word Reading Difficulties on Anxiety Symptoms in Youth

This study examined whether domain-general cognitive weaknesses in processing speed (PS) or executive functioning (EF) moderate the relation between word reading scores and anxiety such that lower word reading scores in combination with lower cognitive scores are associated with higher anxiety symptoms. The sample consisted of 755 youth ages 8-16 who were recruited as part of the Colorado Learning Disabilities Research Center twins study. Lower scores on PS (R2 = .007, p = .014), EF (R2 = .009, p = .006), and word reading (R2 = .006-.008, p = .010-.032) were associated with higher anxiety scores. In addition, the word reading × cognitive interactions were significant such that lower scores on PS (R2 = .010, p = .005) or EF (R2 = .013, p = .010) combined with lower word reading were associated with higher-than-expected anxiety symptoms. Results suggest that weaknesses in PS, EF, and word reading are modestly associated with higher anxiety symptoms, and these anxiety symptoms may be compounded in youth with both PS or EF weaknesses and word reading difficulties. These findings can guide assessment approaches for identifying youth with word reading challenges who may be at increased risk for anxiety.

A network approach to dyslexia: Mapping the reading network

Research on the etiology of dyslexia typically uses an approach based on a single core deficit, failing to understand how variations in combinations of factors contribute to reading development and how this combination relates to intervention outcome. To fill this gap, this study explored links between 28 cognitive, environmental, and demographic variables related to dyslexia by employing a network analysis using a large clinical database of 1,257 elementary school children. We found two highly connected subparts in the network: one comprising reading fluency and accuracy measures, and one comprising intelligence-related measures. Interestingly, phoneme awareness was functionally related to the controlled and accurate processing of letter-speech sound mappings, whereas rapid automatized naming was more functionally related to the automated convergence of visual and speech information. We found evidence for the contribution of a variety of factors to (a)typical reading development, though associated with different aspects of the reading process. As such, our results contradict prevailing claims that dyslexia is caused by a single core deficit. This study shows how the network approach to psychopathology can be used to study complex interactions within the reading network and discusses future directions for more personalized interventions.

Examining fidelity reporting within studies of foundational reading interventions for elementary students with or at risk for dyslexia

Early access to evidence-based reading intervention improves outcomes for students with or at risk for reading difficulties. Additionally, teacher implementation of reading interventions plays a key role in the efficacy of reading interventions. Previous research suggests the influence of intervention implementation fidelity on student language and literacy outcomes is more significant for lower-performing students and students with disabilities, such as dyslexia. However, recent syntheses have suggested that less than half of reading intervention studies report treatment fidelity data. This meta-analysis examined fidelity reporting within reading intervention studies for students with or at risk for dyslexia in Grades K-5. We aimed to record the frequency and extent of fidelity reporting, explore associations between study or intervention features and fidelity reporting, and compare mean intervention effect sizes for studies reporting fidelity and those that did not. A total of 51 studies were included. Results indicated that 75% of studies reported fidelity data. Studies reporting fidelity primarily focused on adherence and dosage data with little to no information reported for other dimensions of fidelity (i.e., quality, responsiveness, differentiation). Suggestions for improving reporting of treatment fidelity data are discussed.

Analysis of Psychological and Social Functioning in Undergraduate Students with a Specific Learning Disorder (SLD)

It is considered to be particularly interesting to enrich the scientific overview investigating the comorbidities of specific learning disorders (SLDs) in young adults. Therefore, this study aims to investigate the psychosocial and relational profiles associated with the presence of learning difficulties in a population of university students. The hypothesis is that young adults with SLDs have lower psychological and socio-relational functioning than their typical-development peers. We further hypothesized that the socio-relational difficulties of students with SLDs could be explained not only by referring to the presence of a learning disorder, but also by considering some variables that may follow the experience of students with SLDs. The results highlighted that students with SLDs, compared to their typical-development peers, have low self-efficacy, high academic anxiety scores, emotional problems, and issues with peers. We finally suggest considering these aspects as early as the diagnostic process to facilitate an effective treatment plan for learning disorders to prevent, in terms of developmental trajectory, the manifestation of these aspects in adulthood.

Telerehabilitation Pathways in Specific Learning Disorders: Improving Reading and Writing

Telerehabilitation has proved to be a useful tool for neurodevelopmental disorders in allowing timely and intensive intervention and preventing relapses; it is also widely used for specific learning disabilities (SLD), showing significant effects on reading abilities, but variables linked to its effectiveness have not been studied yet. The present study was aimed at testing the effectiveness of telerehabilitation on reading and writing in SLD children, comparing different treatment pathways, and considering the impact of training intensity and executive functions. Seventy-three children were enrolled (telerehabilitation group: 48 children, waiting list group: 25 children). The results showed significant improvements in reading fluency, text dictation, and executive functions in the training group. Children attending a combined training including reading tasks and rapid automatized naming processes improved in word reading fluency and text dictation. The number of training sessions and the change in executive functions significantly correlated with changes in reading accuracy. Here we show a new contribution to telerehabilitation research in SLD: telerehabilitation significantly enhanced learning abilities and executive functions. Training based on the learning task and the underlying processes significantly increased not only reading speed, according to previous studies, but also writing accuracy. The findings' implications in clinical research and practice are discussed.

Mathematics Difficulties and Psychopathology in School-Age Children

This study investigated the relationship between mathematics difficulties and psychopathology in a large community sample (N = 881) of youth (8-18 years of age) in the United States. The primary aims of the study were to (a) test the associations between mathematics difficulties and specific components of internalizing, externalizing, attention, and social problems; (b) examine potential age and gender differences; and (c) investigate the longitudinal relationship between mathematics and psychopathology using 5-year follow-up data. Results indicated that individuals with mathematics difficulties exhibited elevations in most dimensions of psychopathology, including anxiety, depression, externalizing behaviors, attention problems, and social problems. Furthermore, mathematics impairment was associated with internalizing problems, rule-breaking behaviors, inattention, and social problems even after controlling for comorbid reading difficulties. Results suggested that the associations between mathematics and psychopathology are generally similar in males and females. Finally, preliminary longitudinal evidence suggested that initial mathematics difficulties predicted elevations of conduct disorder, rule-breaking behavior, inattention, hyperactivity, and social problems at follow-up, with several of these associations remaining significant even after controlling for initial reading. In contrast, there was no significant association between initial mathematics ability and internalizing symptoms at follow-up, demonstrating some amelioration of internalizing symptoms over time.

Specific Learning Disabilities and Emotional-Behavioral Difficulties: Phenotypes and Role of the Cognitive Profile

Specific Learning Disabilities (SLD) are often associated with emotional-behavioral problems. Many studies highlighted a greater psychopathological risk in SLD, describing both internalizing and externalizing problems. The aims of this study were to investigate the emotional-behavioral phenotype through the Child Behavior Checklist (CBCL), and evaluate the mediating role of background and cognitive characteristics on the relationship between CBCL profile and learning impairment in children and adolescents with SLD. One hundred and twenty-one SLD subjects (7-18 years) were recruited. Cognitive and academic skills were assessed, and parents completed the questionnaire CBCL 6-18. The results showed that about half of the subjects manifested emotional-behavioral problems with a prevalence of internalizing symptoms, such as anxiety and depression, over externalizing ones. Older children showed greater internalizing problems than younger ones. Males have greater externalizing problems compared to females. A mediation model analysis revealed that learning impairment is directly predicted by age and familiarity for neurodevelopmental disorders and indirectly via the mediation of the WISC-IV/WAIS-IV Working Memory Index (WMI) by the CBCL Rule-Breaking Behavior scale. This study stresses the need to combine the learning and neuropsychological assessment with a psychopathological evaluation of children and adolescents with SLD and provides new interpretative insights on the complex interaction between cognitive, learning, and emotional-behavioral phenotypes.

Economic evaluation of dyslexia intervention

In many countries, intervention costs are not covered by public health care. A critical basis for deciding whether an intervention is covered or not is to analyse the relation between benefits and costs of the intervention, and to quantify the consequential costs. In this study, a cost-utility analysis was computed to investigate the costs of individualized dyslexia intervention while quantifying the benefit in terms of health-related quality of life in a sample of 36 individuals with dyslexia. In addition, educational outcomes and costs of untreated dyslexia for the society were estimated using information for class repetition, school success, and unemployment rates from previous studies and official statistics. A significant increase in quality of life with medium effect sizes was found across all quality-of-life measures. Increases in quality of life were domain-specific, thus occurring specifically in those domains that are affected by learning disorders. The cost-utility ratio was 9,782 Euros per quality adjusted life years (QALYs), which is in line with similar therapy forms, such as speech therapy. The loss of productivity for untreated dyslexia in the German population was estimated for class repetition and reduced income due to lower school degrees. The cost-utility analysis and the calculation of consequential costs suggest that the dyslexia intervention is cost-effective.

Understanding Mental Health in Developmental Dyslexia: A Scoping Review

Children with dyslexia are at elevated risk of internalising and externalising mental health concerns. Our aim was to scope the extent and nature of the literature investigating factors which may influence this association. We systematically searched the peer-reviewed and grey literature with no restrictions on the date. We included both qualitative and quantitative studies. Inclusion criteria included: (1) a focus on childhood (≤18 years) reading/learning difficulties; (2) internalising and/or externalising symptoms; and (3) a potentially modifiable third factor (e.g., self-esteem). Ninety-eight studies met the inclusion criteria. We organised the studies according to individual, family, and community-level third factors. Whilst a range of third factors were identified, relatively few researchers tested associations between the third factor and mental health in the context of dyslexia. Furthermore, there was a focus on primary rather than secondary school experience and a reliance, in many cases, on teacher/parent perspectives on children's mental health. Future researchers are encouraged to explore links between socio-emotional skills, coping strategies, school connectedness, and mental health in the context of dyslexia. Research of this nature is important to assist with the identification of children who are more (or less) at risk of mental health concerns and to inform tailored mental health programs for children with dyslexia.

Sex Differences in Comorbidity Combinations in the Swedish Population

High comorbidity rates, especially mental–physical comorbidity, constitute an increasing health care burden, with women and men being differentially affected. To gain an overview of comorbidity rates stratified by sex across a range of different conditions, this study examines comorbidity patterns within and between cardiovascular, pulmonary, skin, endocrine, digestive, urogenital, musculoskeletal, neurological diseases, and psychiatric conditions. Self-report data from the LifeGene cohort of 31,825 participants from the general Swedish population (62.5% female, 18–84 years) were analyzed. Pairwise comorbidity rates of 54 self-reported conditions in women and men and adjusted odds ratios (ORs) for their comparison were calculated. Overall, the rate of pairwise disease combinations with significant comorbidity was higher in women than men (14.36% vs. 9.40%). Among psychiatric conditions, this rate was considerably high, with 41.76% in women and 39.01% in men. The highest percentages of elevated mental–physical comorbidity in women were found for musculoskeletal diseases (21.43%), digestive diseases (20.71%), and skin diseases (13.39%); in men, for musculoskeletal diseases (14.29%), neurological diseases (11.22%), and digestive diseases (10%). Implications include the need for integrating mental and physical health care services and a shift from a disease-centered to an individualized, patient-centered focus in clinical care.

Evidence of Altered Functional Connectivity at Rest in the Writing Network of Children with Dyslexia

Aim. Handwriting abilities in children with dyslexia (DYS) are not well documented in the current literature, and the presence of graphomotor impairment in addition to spelling impairment in dyslexia is controversial. Using resting-state functional connectivity (RSFC), the present study aims to answer the following question: are there markers of graphomotor impairment at rest in DYS children? Method. The participants were children with DYS and typically developing (TD) children (n = 32) from French-speaking primary schools (M_age = 9.3 years). The behavioural evaluation consisted of spelling and handwriting measures. Participants underwent a resting-state fMRI scan. Results. Analyses of RSFC focused on a brain region responsible for graphomotor processes—the graphemic/motor frontal area (GMFA). The RSFC between the GMFA and all other voxels of the brain was measured. Whole-brain ANOVAs were run to compare RSFC in DYS and TD children. The results demonstrated reduced RSFC in DYS compared to TD between the GMFA and brain areas involved in both spelling processes and motor-related processes. Conclusions. For the first time, this study highlighted a disruption of the writing network in DYS. By identifying functional markers of both spelling and handwriting deficits at rest in young DYS participants, this study supports the presence of graphomotor impairment in dyslexia.

Students with dyslexia between school and university: Post-diploma choices and the reasons that determine them. An Italian study

Although the number of students with dyslexia enrolled in Italian universities is constantly growing, their presence remains relatively limited. The aim of this study was therefore to investigate the choices made by students with dyslexia in relation to university studies, and the underlying reasons for their choices. This study also compares these choices for students with and without dyslexia. In all, 440 high school students and their families agreed to take part in this project. Socio-demographic data was collected for the 47 students with dyslexia and 47 class-matched students without dyslexia, along with information on their current schools and their future educational plans. A specially developed questionnaire was used for the students, in combination with structured interviews with their families. The results show significant differences between these groups regarding both choices for university studies and the underlying motivations for these choices. Furthermore, certain psychological and emotional factors are implicated here in the decisions of the students with dyslexia regarding both university studies and their underlying reasons. Future research is needed to further investigate these factors in the educational choices of students with dyslexia.

Drawing a New Picture: Children with Developmental Dyslexia Exhibit Superior Nonverbal Creativity

BACKGROUND

Creativity and literacy are essential skills that today's children are expected to develop. However, the question of whether children with developmental dyslexia, a severe difficulty in reading and writing, exhibit any intact creativity strengths remains controversial. This study examined creativity strengths across verbal, figural, and nonverbal modalities, and the relations among creativity, nonverbal intelligence, and literacy skills, in younger and older Chinese children with and without developmental dyslexia.

METHODS

Two age groups of Chinese children with developmental dyslexia (Grade 2: N = 62; Grades 4-5: N = 62) and their age matched controls (Grade 2: N = 61; Grades 4-5: N = 61) were assessed on fluency and originality of verbal, figural, and nonverbal creativity, as well as on nonverbal intelligence, vocabulary, working memory, Chinese word reading accuracy and fluency, and word dictation.

RESULTS

Multifactorial analysis of variance demonstrated that regardless of grade level, children with developmental dyslexia exhibited higher nonverbal creativity than, and comparable figural creativity to, their typically developing peers. Moreover, the partial correlation analysis revealed creativity was not significantly correlated with nonverbal intelligence and literacy skills.

CONCLUSIONS

These findings suggest that children with dyslexia possess strengths and even advantages in nonverbal creativity and that the relationship between intelligence and/or literacy and creativity is negligible.

Comparison on Well-Being, Engagement and Perceived School Climate in Secondary School Students with Learning Difficulties and Specific Learning Disorders: An Exploratory Study

Reading and writing skills influence the social status of students, exerting effects not only on learning, but also on wellbeing. This study aimed to assess the impact of diagnosis of specific learning disorder on well-being in secondary-school students, comparing students with a diagnosis of specific learning disorder (SLD-group), students showing learning difficulties without diagnosis (LD-group) and students without learning difficulties (control-group). Students were tested with neuropsychological screening tests in order to identify learning difficulties and were further assessed by means of psychological and school well-being questionnaires. The results show that LD group perceive themselves as having a low sense of mastery and autonomy, less interest and engagement in daily activities and low peer social support than their schoolmates. This result highlights, for the LD group, a low well-being experience, which is not observed in the SLD and control groups. On the contrary, SLD group students do not differ from control group students in any dimensions except for the perceived parents' support and involvement in school life, in which the SLD group show the highest scores. This work underlines the importance of having a diagnosis as it seems to work as a protective factor for both the psychological and school well-being of the student.

Similarities and Differences in the Learning Profiles of Adolescents with SLD and SLI in Mathematics-A Preliminary Analysis

SLI and SLD constitute two independent neurodevelopmental disorders, which frequently cause challenges in the diagnosis process, especially due to their nature. This has caused disagreement among clinicians regarding their recognition as separate or overlapping disorders. The objective of the study was to enlighten the path of valid diagnosis and intervention during adolescence when the two disorders change their manifestation and overlap. Two hundred Greek adolescents (140 boys and 60 girls), 124 already diagnosed with SLD and 76 diagnosed with SLI, 12-16 years old, participated in the study. All participants were assessed in reading, oral and written language and mathematics (mathematical operations and mathematical reasoning) along with IQ testing. In order to determine statistically significant differences, the chi-square test, independent samples t-test, odds ratios and their 95 per cent confidence intervals were implemented. The results revealed that the SLI group presented significantly greater difficulties than SLD in their overall cognitive-mental profile and in most language and mathematical measurements (number concept, executive-procedural part of solving operations and mathematical reasoning). The similarity of the two groups was mainly detected in their deficient metacognitive, metalinguistic and metamnemonic strategies. The research concludes that SLD adolescents managed to overcome their difficulties to a significant degree, while adolescents with SLI still struggle with many learning areas.

Enhanced visceromotor emotional reactivity in dyslexia and its relation to salience network connectivity

Dyslexia is a neurodevelopmental disorder mainly defined by reading difficulties. During reading, individuals with dyslexia exhibit hypoactivity in left-lateralized language systems. Lower activity in one brain circuit can be accompanied by greater activity in another, and, here, we examined whether right-hemisphere-based emotional reactivity may be elevated in dyslexia. We measured emotional reactivity (i.e., facial behavior, physiological activity, and subjective experience) in 54 children ages 7-12 with (n = 32) and without (n = 22) dyslexia while they viewed emotion-inducing film clips. Participants also underwent task-free functional magnetic resonance imaging. Parents of children with dyslexia completed the Behavior Assessment System for Children, which assesses real-world behavior. During film viewing, children with dyslexia exhibited significantly greater reactivity in emotional facial behavior, skin conductance level, and respiration rate than those without dyslexia. Across the sample, greater emotional facial behavior correlated with stronger connectivity between right ventral anterior insula and right pregenual anterior cingulate cortex (pFWE<.05), key salience network hubs. In children with dyslexia, greater emotional facial behavior related to better real-world social skills and higher anxiety and depression. Our findings suggest there is heightened visceromotor emotional reactivity in dyslexia, which may lead to interpersonal strengths as well as affective vulnerabilities.

The prevalence of psychiatric comorbid disorders among children with specific learning disorders: a systematic review

Background

Understanding comorbidity of psychiatric disorders with specific learning disorders (SLD) is important because the presence of any additional disorder to the learning disability may affect the severity and prognosis of the SLD symptoms and requires specific treatments and interventions.

Main body of the abstract

The purpose of this systematic review was to describe the prevalence of comorbid psychiatric disorders among children with SLD between 6 and 18 years. English studies published between 2013 and 2018 were located through searches of PubMed and ScienceDirect. In this review, only 5 articles met the inclusion criteria. The quality of the included studies was assessed with the Cochrane risk of the bias assessment tool. The prevalence of ADHD and anxiety disorder was reported in 4 studies. Prevalence of conduct disorder (CD) and depression was reported by 3 studies, and 2 studies reported the prevalence of oppositional defined disorders (ODD). Although this review included a small number of studies that used a diversity of methods to diagnose psychiatric disorders, the results of the prevalence rates were homogenous.

Short conclusion

The included studies reported that ADHD had the highest prevalence rate among children with SLD followed by anxiety and depressive disorders. Both CD and ODD were the least prevalent and are linked to the existence of ADHD. Further worldwide future studies are needed to estimate the prevalence rate of such psychiatric disorders among children with SLD, taking into consideration the use of agreed assessment methods for diagnosing the psychiatric disorders and the SLD.

Pre-literacy heterogeneity in Dutch-speaking kindergartners: latent profile analysis

Research demonstrated that a dyslexia diagnosis is mainly given after the most effective time for intervention has passed, referred to as the dyslexia paradox. Although some pre-reading cognitive measures have been found to be strong predictors of early literacy acquisition, i.e., phonological awareness (PA), letter knowledge (LK), and rapid automatized naming (RAN), more insight in the variability of pre-reading profiles might be of great importance for early identification of children who have an elevated risk for developing dyslexia and to provide tailor-made interventions. To address this issue, this study used a latent profile analysis (LPA) to disentangle different pre-reading profiles in a sample of 1091 Dutch-speaking kindergartners. Four profiles emerged: high performers (16.50%), average performers (40.24%), below-average performers with average IQ (25.57%), and below-average performers with below-average IQ (17.69%). These results suggested two at-risk profiles diverging in IQ, which are presumably more likely to develop dyslexia later on. Although below-average profiles differed significantly in rapid naming and IQ, no clear evidence for the double-deficit theory was found in Dutch-speaking kindergartners. Educational level and reading history of the parents appeared to be predictive for children's classification membership. Our results point towards the heterogeneity that is already present in kindergartners and the possibility to identify at-risk profiles prior to reading instruction, which may be the foundation for earlier targeted interventions. However, more extended research is needed to determine the stability of these profiles across time and across different languages.

Measuring Test Anxiety in Primary and Middle School Children

Abstract. The increasing use of tests to assess academic competences has been associated with higher levels of test anxiety (TA) in children, underlining the importance of identifying this emotional problem and sustain academic achievement. This study aimed to contribute to the extant literature on the assessment of TA by examining the psychometric properties of the Test Anxiety Questionnaire for Children (TAQ-C), in primary and middle school children. In Study 1 ( N = 123), we selected 24 items from a wider initial pool, dividing them into scales measuring Thoughts, Autonomic Reactions, Off-Task Behaviors, and Social Derogation, to develop the TAQ-C. In Study 2 ( N = 899), the psychometric properties of this set of scales were assessed in students attending primary and middle school. Analyses supported the bifactor latent structure of the TAQ-C, invariance across educational levels and gender, concurrent and convergent validity, and test–retest reliability. Overall, the TAQ-C is a promising tool for assessing TA in primary and middle school students. Implications and directions for future research are discussed.

Associations between Learning and Behavioral Difficulties in Second-Grade Children

Learning and behavioral difficulties often emerge during the first years of primary school and are one of the most important issues of concern for families and schools. The study was aimed at investigating the co-occurrence of difficulties between academic learning and emotional-behavioral control in typically developing school children and the moderating role of sex. A sample of 640 second-grade school children participated in the study. This study used the Strengths and Difficulties Questionnaire to measure the emotional and behavioral difficulties and a battery of objective and standardized tests to evaluate the learning skills in children. In this sample 7% to 16% of children performed below the normal range in reading and/or arithmetic tests. Mixed models showed that children’s hyperactive behaviors were positively related to both reading and math difficulties, and emotional problems correlated negatively with reading accuracy. The more children displayed behavioral difficulties, the more they were exposed to the risk of worsening reading and math performance, especially for girls. The result that among different emotional-behavioral problems within the school setting, hyperactivity behaviors and emotional difficulties are related to learning difficulties with a moderate effect of sex, needs to be taken into account in screening and prevention programs for learning difficulties in order to not disregard the complexity of the associated profiles.

An Early Reading Assessment Battery for Multilingual Learners in Malaysia

The aim of the study was to develop a new comprehensive reading assessment battery for multi-ethnic and multilingual learners in Malaysia. Using this assessment battery, we examined the reliability, validity, and dimensionality of the factors associated with reading difficulties/disabilities in the Malay language, a highly transparent alphabetic orthography. In order to further evaluate the reading assessment battery, we compared results from the assessment battery with those obtained from the Malaysian national screening instrument. In the study, 866 Grade 1 children from multi-ethnic and multilingual backgrounds from 11 government primary schools participated. The reading assessment battery comprised 13 assessments, namely, reading comprehension, spelling, listening comprehension, letter name knowledge, letter name fluency, rapid automatized naming, word reading accuracy, word reading efficiency, oral reading fluency, expressive vocabulary, receptive vocabulary, elision, and phonological memory. High reliability and validity were found for the assessments. An exploratory factor analysis yielded three main constructs: phonological-decoding, sublexical-fluency, and vocabulary-memory. Phonological-decoding was found to be the most reliable construct that distinguished between at-risk and non-at-risk children. Identifying these underlying factors will be useful for detecting children at-risk for developing reading difficulties in the Malay language. In addition, these results highlight the importance of including a range of reading and reading-related measures for the early diagnosis of reading difficulties in this highly transparent orthography.

Reintroducing Dyslexia: Early Identification and Implications for Pediatric Practice

Dyslexia is a common learning disorder that renders children susceptible to poor health outcomes and many elements of socioeconomic difficulty. It is commonly undiagnosed until a child has repeatedly failed to learn to read in elementary school; this late diagnosis not only places the child at an academic disadvantage but also can be a precursor to psychiatric comorbidities such as anxiety and depression. Genetic and neuroimaging research have revealed that dyslexia is heritable and that it is undergirded by brain differences that are present even before reading instruction begins. Cognitive-behavioral research has revealed that there are early literacy skill deficits that represent red flags for dyslexia risk and can be measured at a preschool age. Altogether, this evidence points to dyslexia as a disorder that can be flagged by a pediatrician before school entry, during a period of heightened brain plasticity when interventions are more likely to be effective. In this review, we discuss the clinical implications of the most recent advances in dyslexia research, which converge to indicate that early identification and screening are crucial to the prevention or mitigation of adverse secondary consequences of dyslexia. We further highlight evidence-based and practical strategies for the implementation of early risk identification in pediatric practice so that physicians can be empowered in their ability to treat, educate, and advocate for their patients and families with dyslexia.

Behavior Problems and Depressive Symptoms in Developmental Dyslexia: Risk Assessment in Brazilian Students

Objective

To investigate if students with developmental dyslexia (DD) have more behavior problems and depressive symptoms than students without learning difficulties.

Method

Participants were 61 students, aged 7-14 years, including 31 with interdisciplinary DD diagnosis and 30 without learning disabilities. We collected data from parents, using the children’s behavior checklist (CBCL), and from students, using the children’s depression inventory (CDI).

Results

The DD group had higher CBCL averages for anxiety, depression, withdrawal, rule-breaking behaviors, aggressiveness, and social, attentional and thought problems. They also showed higher results for the internalizing and externalizing categories, others and total. In the CDI, DD students had higher averages for total score and for the following symptoms: negative self-evaluation, guilt, suicidal thoughts, feeling concern, performance comparison, sleeping difficulties, fatigue, and problems in interacting with peers at school.

Conclusions

We discuss the results in terms of implications for DD diagnosis and intervention. Parent reports indicate a higher frequency of behavior problems in students with DD diagnosis. Those students also demonstrate more symptoms of depression than students without learning difficulties.

Internalizing Symptoms in Developmental Dyslexia: A Comparison Between Primary and Secondary School

Although the relationship between developmental dyslexia (DD) and the risk of occurrence of internalizing symptomatology has been widely investigated in the extant literature, different findings have been reported. In this study, two experiments with two general purposes are presented. The first study investigates whether the differences in the severity of internalizing symptoms between DD and controls are greater in students attending secondary school than in those attending primary school. Sixty-five DD and 169 controls attending primary and secondary school took part in the first study. The diagnosis of dyslexia was obtained from standardized reading tests; internalizing symptom severity was assessed with the Self Administrated Psychiatric Scales for Children and Adolescents questionnaire. The results showed that adolescents with dyslexia had an increased level of self-perceived anxiety, depression and somatic symptoms, whereas no significant differences between DD and controls emerged in childhood. In the second study, a cohort of adolescents attending secondary school (DD = 44; controls = 51) was closely analyzed to clarify whether contextual and subjective factors could contribute toward exacerbating the risk of internalizing symptomatology at that age. Internalizing symptom severity was assessed with the Child Behavior Checklist, Youth Self Report questionnaire, decision-making factors were measured with the Melbourne Decision Making Questionnaire, and student’s quality of life was gaged using the Clipper test. The results showed that high levels of internalizing symptoms in DD were associated with a low level of self-esteem and the tendency to react to problematic situations with hyperactivation. By contrast, positive relationships with peers were associated with low symptom severity. In conclusion, the intensified internalizing symptoms that could emerge in adolescents in association with the presence of dyslexia are predicted by social protective and risk factors that are associated with symptom severity. Accordingly, the results suggest that remediation programs for dyslexia should include implementing motivation strategies, self-esteem enhancement activities and building peers networks that, starting in childhood, can prevent the appearance of internalizing symptoms.

Rumination and Emotional Profile in Children with Specific Learning Disorders and Their Parents

Rumination, namely a cognitive process characterized by a repetitive thinking focused on negative feelings and thoughts, is a significant predictor for the onset of internalizing symptoms and has also been found to run in families. Rumination has never been studied in children with specific learning disorders (SLD), a population that, due to its condition, might encounter more difficulties in daily life and is at risk of increased psychological distress, compared to typically developing (TD) peers. The present study covers this gap by examining whether children with SLD, and their parents, tend to use rumination more than TD peers and their parents. The study also explores associations between rumination and both children's and parents' emotional profile. Results on 25 children with SLD and 25 TD peers and their parents (n = 150), showed higher levels of rumination in children with SLD when referring to a negative social situation, as well as higher levels of rumination in both mothers and fathers of children with SLD. Modest correlations between parents' and children's rumination traits were also found. This study offers evidence on rumination as a possible risk factor for children with SLD, particularly considering when they deal with social contexts.

Tell Me a Story: Socio-Emotional Functioning, Well-Being and Problematic Smartphone Use in Adolescents With Specific Learning Disabilities

Although Specific Learning Disabilities (SLD) are described as specific difficulties in one or more academic areas, often socio-emotional problems are also reported to be related to well-being and school engagement. Moreover, recent evidence shows that emotional problems and reduced social support predict problematic use of new technologies, such as a smartphone, that can, in turn, increase these problems. In this study, we aimed to investigate socio-emotional functioning and its relation to well-being, school engagement, and problematic smartphone use. Social and emotional skills of 19 adolescents with a diagnosis of SLD and 19 control adolescents were assessed through a narrative test; adolescents were requested to narrate complete stories elicited by pictures representing social situations. Information on well-being and problematic smartphone use were collected through questionnaires. The comparison between groups showed differences in cognitive-social skills, although no significant differences in emotional functioning were found. Additionally, the perception of the social environment as supportive and trustworthy was related to general well-being for both groups, whereas the perception of limits and rules set by the adult world appeared to be related to a decreased investment in learning processes only for the SLD students. Finally, correlation analysis showed that smartphone use was associated with reduced perception of social support and to a decreased ability to understand and solve social situations. These results assert the critical role played by social information processing and social support in terms of well-being in adolescence, and contribute to enhancing knowledge of the mechanisms underlying problematic smartphone use in a clinical sample.

The Impact of School Climate on Well-Being Experience and School Engagement: A Study With High-School Students

The aim of this work is to investigate the factors promoting students' engagement at school and supporting their well-being experience. According to the Positive Education there is a strong relationship between school environment and student's well-being. Moreover, the quality of the school climate perceived by the students was found to influence engagement in school activities, as well. In this study, 153 students (M = 67) attending 10th grade were presented with tests and questionnaires to assess individual assets (personality traits, literacy skills), emerging appraisals (school-climate, well-being experience) and emerging actions (school engagement), according to the Student Well-Being Model. Path analysis showed that the best model does include neither individual assets nor direct effect of school climate on engagement, as the effect of school climate on engagement is mediated by well-being experience. The main result is that school climate has been confirmed as an important factor to be considered to improve engagement in school activities, but it is effective only when its influence can modify the well-being experience of the students. Moreover, the lack of significant effects of individual assets in the model suggests that improving school climate means to support well-being experience and, indirectly school engagement, irrespective to learning abilities and personality traits. This work encourages working in/with schools to implement positive education programs that support and sustain a positive school climate and culture for school-community wellbeing.

Impact of mentoring on socio-emotional and mental health outcomes of youth with learning disabilities and attention-deficit hyperactivity disorder

BACKGROUND

Learning disabilities (LD) and attention-deficit hyperactivity disorder (ADHD) are often accompanied by significant socio-emotional impairments and mental health challenges. However, there is a lack of controlled, quantitative research on potential interventions to address this issue. The current study evaluated the impact of a near-peer mentoring program for youth with LD/ADHD designed to promote socio-emotional well-being.

METHODS

Youth with LD/ADHD who participated in the mentoring program (Mentored; n=99) were compared to non-mentored youth with LD/ADHD (Control-NM; n=51) and typically-developing youth without LD/ADHD (Control-TD; n=81) pre-mentoring in the fall, and post-mentoring in the spring. Participants were assessed on self-report measures of anxiety, depression, interpersonal relations, and self-esteem.

RESULTS

Youth with LD/ADHD showed significantly higher scores of depression and significantly lower scores of interpersonal relations compared to the Control-TD group at fall baseline. The depression and self-esteem scores of the Mentored group significantly decreased and increased respectively after mentoring. These changes were associated with mentee-perceived mentorship quality. The Control-NM group showed significant decreases in both self-esteem and interpersonal relations, as well as increases in depression over time, while the Control-TD group remained stable across all measures.

CONCLUSIONS

Results suggest that mentoring shows promise as a potential intervention for youth with LD/ADHD and co-occurring socio-emotional and mental health difficulties. The study is the first, to our knowledge, to quantify the effect of a near-peer mentoring program on youth with LD/ADHD in a design with two control groups. Implications for research and practice involving LD, ADHD, and mental health disorders are discussed.

Simultaneous EEG and fMRI reveals stronger sensitivity to orthographic strings in the left occipito-temporal cortex of typical versus poor beginning readers

The level of reading skills in children and adults is reflected in the strength of preferential neural activation to print. Such preferential activation appears in the N1 event-related potential (ERP) over the occipitotemporal scalp after around 150–250 ms and the corresponding blood oxygen level dependent (BOLD) signal in the ventral occipitotemporal (vOT) cortex. Here, orthography-sensitive (print vs. false font) processing was examined using simultaneous EEG-fMRI in 38 first grade children with poor and typical reading skills, and at varying familial risk for developmental dyslexia. Coarse orthographic sensitivity was observed as an increased activation to print in the N1 ERP and in the BOLD signal of individually varying vOT regions in 57% of beginning readers. Finer differentiation in processing orthographic strings (words vs. nonwords) further occurred in specific vOT clusters. Neither method alone showed robust differences in orthography-sensitive processing between typical and poor reading children. Importantly, using single-trial N1 ERP-informed fMRI analysis, we found differential modulation of the orthography-sensitive BOLD response in the left vOT for typical readers only. This result, thus, confirms subtle functional alterations in a brain structure known to be critical for fluent reading at the very beginning of reading instruction.

Children with dyslexia in different cultures: Investigation of anxiety and coping strategies of children with dyslexia in Indonesia and Germany

Hitherto the majority of research on anxiety and coping was undertaken on individuals with specific profiles (i.e., individuals with specific difficulties or in cross-cultural settings). However, to our knowledge, no studies have combined cross-cultural and specific difficulty settings to grant a complex analysis of this paradigm nor conducted an investigation of children to reveal the developmental trend in this phenomenon. This study investigates the anxiety profile and coping strategies of children with and without dyslexia from different cultures. A total of 124 children ranging from the age of eight to eleven from Indonesia (n = 64) and Germany (n = 60) were administered a coping and an anxiety scale. Around 50% of the sample were diagnosed with dyslexia and therefore were specifically asked what strategies they implemented in dealing with their difficulties in reading. Findings indicate that dyslexia and cultural factors have distinct contributions in explaining the variance of anxiety and coping strategies. Specifically, dyslexia has a significant effect on separation and generalized anxiety, while an incredible cultural effect is valid for the support-seeking coping strategy. Recommendations for future studies are also discussed.

Reading and writing difficulties and self-rated health among Danish adolescents: cross-sectional study from the FOCA cohort

BACKGROUND

People struggling with reading and writing difficulties may have poor odds of achieving a good and healthy life. Reading and writing difficulties are independent risk factors for not completing education and unemployment, which are essential in order to obtain a good and healthy life. Therefore, the purpose of this study was to investigate the association between reading and writing difficulties and self-rated health among adolescents, and to investigate how mental health mediates the association.

METHODS

A cross-sectional study was performed based on the FOCA cohort, a Danish population-based survey among 9th grade pupils, mainly aged 15- and 16-years old, gathered during the first months of 2017. The study population contained 9748 pupils. The dependent variable was a yes-or-no answer to experiencing limitations in every-day life due to reading and writing difficulties. The independent variable was measured with the SF-36 self-rated health question, dichotomised in high (very good, excellent) and low (good, fair, poor). A logistic regression model was applied.

RESULTS

Among the study population 953 (9.8%) pupils reported having reading and writing difficulties. The adjusted OR of having a low self-rated health was significantly higher among adolescents with reading and writing difficulties than without (1.37 (95% CI: 1.14-1.66)). Loneliness and perceived stress, explained a minor part of the association, OR attenuated from 1.77 (95% CI: 1.51-2.09) in the crude model to 1.47 (95% CI: 1.23-1.74) in a more adjusted model.

CONCLUSION

Adolescents with reading and writing difficulties are not only struggling with reading and writing difficulties but experiencing also low self-rated health. Mental health only explained a minor part of this association. To clarify whether causal relationship between reading and writing difficulties and self-rated health may exist, longitudinal studies are needed. If support for the hypothesised causality is found early identification of reading and writing difficulties is important, to prevent future health inequality in adolescents with reading and writing difficulties.

Health-related quality of life and psychological wellbeing of children with Specific Learning Disorders and their mothers

BACKGROUND

Literature suggests that Specific Learning Disorders (SpLD) can cause impairment of Health-Related Quality of Life (HRQoL) and psychological well-being of children, and that this condition potentially affects parents' quality of life and well-being too.

AIMS

This study aims first to explore HRQoL and psychological well-being among children with SpLD and second among mothers of children with SpLD.

METHODS AND PROCEDURES

Thirty children aged 8-14 years diagnosed as having SpLD and their mothers completed a battery of scales to assess children's HRQoL and psychological well-being. Mothers also completed a battery of instruments to explore their personal HRQoL and psychological well-being.

RESULTS

Compared with the general population, children with SpLD reported significantly lower level of psychosocial health, and mothers had a higher probability of being anxious and/or depressed.

CONCLUSIONS AND IMPLICATIONS

This study supports previous research about impaired HRQoL, symptoms of generalized anxiety, school-related anxiety and depressed mood in children with SpLD. Moreover, it provides evidence that mothers of children with SpLD may experience stress in coping with their child's disability and develop socio-emotional symptoms such as anxiety. Implications concern the need to implement effective supportive services among children with SpLD and their parents.

Genome-wide association scan identifies new variants associated with a cognitive predictor of dyslexia

Developmental dyslexia (DD) is one of the most prevalent learning disorders, with high impact on school and psychosocial development and high comorbidity with conditions like attention-deficit hyperactivity disorder (ADHD), depression, and anxiety. DD is characterized by deficits in different cognitive skills, including word reading, spelling, rapid naming, and phonology. To investigate the genetic basis of DD, we conducted a genome-wide association study (GWAS) of these skills within one of the largest studies available, including nine cohorts of reading-impaired and typically developing children of European ancestry (N = 2562-3468). We observed a genome-wide significant effect (p < 1 × 10-8) on rapid automatized naming of letters (RANlet) for variants on 18q12.2, within MIR924HG (micro-RNA 924 host gene; rs17663182 p = 4.73 × 10-9), and a suggestive association on 8q12.3 within NKAIN3 (encoding a cation transporter; rs16928927, p = 2.25 × 10-8). rs17663182 (18q12.2) also showed genome-wide significant multivariate associations with RAN measures (p = 1.15 × 10-8) and with all the cognitive traits tested (p = 3.07 × 10-8), suggesting (relational) pleiotropic effects of this variant. A polygenic risk score (PRS) analysis revealed significant genetic overlaps of some of the DD-related traits with educational attainment (EDUyears) and ADHD. Reading and spelling abilities were positively associated with EDUyears (p ~ [10-5-10-7]) and negatively associated with ADHD PRS (p ~ [10-8-10-17]). This corroborates a long-standing hypothesis on the partly shared genetic etiology of DD and ADHD, at the genome-wide level. Our findings suggest new candidate DD susceptibility genes and provide new insights into the genetics of dyslexia and its comorbities.

The lost children: The underdiagnosis of dyslexia in Italy. A cross-sectional national study

Background

Developmental dyslexia is one of the most common neurobehavioral disorders affecting children, but prevalence data on this condition are poor. The objective of the present study is to determine the prevalence of dyslexia in Italy in an unselected school population, using clearly defined diagnostic criteria and methods.

Methods

Cross-sectional study carried out in nine Italian Regions: two located in Northern Italy (Friuli Venezia Giulia and Veneto), three in Central Italy (Marche, Lazio and Umbria) and four in Southern Italy (Abruzzo, Molise, Puglia and Sardegna). Three consecutive levels of screening were carried out: the first two at school, to screen the population and identify children with suspect dyslexia; the last in centers with multi-professional staff specialized in learning disabilities to confirm the diagnosis. The key outcome measure is the prevalence of dyslexia, defined as the ratio between the number of children confirmed positive at the third level of screening and the total number of children enrolled in the study.

Results

We finally recruited 11094 children aged 8–10 years, of which 9964 constituted the final working sample after applying exclusion criteria and including only children who received parents’ consent to participate. The prevalence of dyslexia in the whole sample was 3.5% (95% CI 3.2–3.9%), with little differences between Northern, Central and Southern Italy (respectively 3.6%, 3.2% and 3.7%). In almost two out of three children with dyslexia the disorder had not been previously diagnosed.

Conclusions

This study confirms that in primary school children at the age of 8–10 years in Italy dyslexia is widely underestimated. Reliable data on dyslexia prevalence are needed to allocate necessary human and financial resources both to Health Services and Schools, ensuring timely support to children and families.

The association between poor reading and internalising problems: A systematic review and meta-analysis

Numerous studies have demonstrated an association between learning disabilities and internalising problems such as anxiety and depression. However, our understanding of this association for people with specific types of learning disability - such as poor reading - is poorly understood. Here, we present the first systematic review and meta-analysis of studies that have examined associations between poor reading and internalising problems - including anxiety and depression - in children, adolescents, and adults. Our systematic search identified 34 studies comprising 16,275 participants (N = 2491 poor readers). Our meta-analysis revealed statistically significant differences between poor readers and typical readers on general measures of internalising problems (d = 0.41), as well as specific measures of anxiety (d = 0.41) and depression (d = 0.23). These outcomes suggest that poor readers are at moderate risk for experiencing internalising problems compared to typical readers, which appears to stem from a greater risk for anxiety than depression.

Simulating reading acquisition: The link between reading outcome and multimodal brain signatures of letter-speech sound learning in prereaders

During reading acquisition, neural reorganization of the human brain facilitates the integration of letters and speech sounds, which enables successful reading. Neuroimaging and behavioural studies have established that impaired audiovisual integration of letters and speech sounds is a core deficit in individuals with developmental dyslexia. This longitudinal study aimed to identify neural and behavioural markers of audiovisual integration that are related to future reading fluency. We simulated the first step of reading acquisition by performing artificial-letter training with prereading children at risk for dyslexia. Multiple logistic regressions revealed that our training provides new precursors of reading fluency at the beginning of reading acquisition. In addition, an event-related potential around 400 ms and functional magnetic resonance imaging activation patterns in the left planum temporale to audiovisual correspondences improved cross-validated prediction of future poor readers. Finally, an exploratory analysis combining simultaneously acquired electroencephalography and hemodynamic data suggested that modulation of temporoparietal brain regions depended on future reading skills. The multimodal approach demonstrates neural adaptations to audiovisual integration in the developing brain that are related to reading outcome. Despite potential limitations arising from the restricted sample size, our results may have promising implications both for identifying poor-reading children and for monitoring early interventions.

Recognizing Psychiatric Comorbidity With Reading Disorders

Reading disorder (RD), a specific learning disorder (SLD) of reading that includes impairment in word reading, reading fluency, and/or reading comprehension, is common in the general population but often is not comprehensively understood or assessed in mental health settings. In education settings, comorbid mental and associated disorders may be inadequately integrated into intervention plans. Assessment and intervention for RD may be delayed or absent in children with frequently co-occurring mental disorders not fully responding to treatment in both school and mental health settings. To address this oversight, this review summarizes current knowledge regarding RDs and common comorbid or co-occurring disorders that are important for mental health and school settings. We chose to highlight RD because it is the most common SLD, and connections to other often comorbid disorders have been more thoroughly described in the literature. Much of the literature we describe is on decoding-based RD (or developmental dyslexia) as it is the most common form of RD. In addition to risk for academic struggle and social, emotional, and behavioral problems, those with RD often show early evidence of combined or intertwined Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition childhood disorders. These include attention deficit hyperactivity disorder, anxiety and depression, disruptive, impulse-control, and conduct disorders, autism spectrum disorders, and other SLDs. The present review highlights issues and areas of controversy within these comorbidities, as well as directions for future research. An interdisciplinary, integrated approach between mental health professionals and educators can lead to comprehensive and targeted treatments encompassing both academic and mental health interventions. Such targeted treatments may contribute to improved educational and health-related outcomes in vulnerable youth. While there is a growing research literature on this association, more studies are needed of when to intervene and of the early and long-term benefits of comprehensive intervention.
