RESUMO

Extensive evidence highlights the significant influence of dyadic, emotional teacher-student relationship (TSR) on students' cognitive functioning, socio-emotional development, and overall well-being. However, it remains unclear whether the TSR construct and its manifestations can be generalized across cultures. This qualitative study investigated TSR among 60 primary school teachers in Belgium, China, and Italy (i.e., countries with varying positions on the collectivistic-individualistic continuum of culture). Through semi-structured interviews and metatheme analysis, the study examined the similarities and differences in TSR across these countries, revealing a nuanced and diverse picture in various cultural contexts. The findings align with the existing TSR model by including dimensions of closeness, conflict, and dependency, while also extending the model to identify additional dimensions such as authority, balance, distance, fairness, increasing student motivation, patience, and strictness. Regarding cultural perspective, teachers from these three countries exhibited similar conceptualizations of closeness, conflict, fairness, increasing student motivation, patience, and strictness, whereas the conceptualization of dependency, authority, balance, and distance may be influenced by (collectivistic versus individualistic) culture. Moreover, the manifestations of TSR varied across countries, highlighting the influence of cultural factors such as cultural norms, collectivistic versus individualistic values, and the perceived legitimacy of teacher authority. These findings shed light on the complexities of TSR across countries and emphasize the significance of culturally sensitive approaches in fostering positive TSR in education.

RESUMO

Introduction: Early relationships with teachers play an important role in children's development and significantly influence students' cognitive and academic performance. Studies suggest that working memory (WM) is a strong predictor of academic achievement, especially of reading and arithmetic outcomes. The associations between teacher-student relationship (TSR) quality, children's WM skills and their academic performance have been reported in numerous observational studies. However, the potentially bidirectional and temporal nature of the relationships between these constructs is understudied. Methods: The purpose of this study was to investigate the relationships between primary school children's WM and TSR by applying a cross-lagged design and measuring these constructs at three time points throughout the academic year. More exploratively, this study investigated how WM and TSR bidirectionally relate to children's academic performance. Results: The findings of this study revealed a temporal relationship between WM and TSR: between WM-related problems in the classroom at baseline and conflict at 3-month follow-up, and between closeness at 3-month follow-up and WM-related problems in the classroom at 5-month follow-up. Moreover, the findings showed a bidirectional relationship between arithmetic performance and WM-related problematic behaviour. Discussion: This study highlights that relationships between the teacher and students play an important role in supporting students' cognitive and academic development. Importantly, this study suggests that children with WM problems may benefit from interventions that focus on improving their relationships with teachers. Additionally, the findings propose that interventions targeting WM may also have positive effects on children's academic performance.

RESUMO

Background: Adolescence is characterized by an increase in the rate of sleep problems, which might be even more pronounced in adolescents with ADHD. This systematic review with meta-analysis aimed to compare sleep in adolescents with and without ADHD, including sleep parameters, both subjectively and objectively measured, sleep problems and sleep hygiene. Methods: Medline, CINAHL, PsycINFO, EMBASE, ERIC, Web of Science, and PubMed databases were searched for studies with case-control designs (published between 1980 and 2022) directly comparing sleep in adolescents (12-25 years) with ADHD to typically developing controls. Standardized mean differences were calculated and a random-effects model was implemented using RevMan. Results: Overall, 6974 titles/abstracts and 205 full texts were screened, resulting in 13 eligible studies. The sample sizes range from 35 to 9846 with in total 2465 adolescents with ADHD and 18,417 controls. The data suggests that adolescents with ADHD report significantly more disturbed subjective sleep parameters (e.g., total sleep time; n = 7, SMD = 0.47, p < .001) and experience more sleep problems compared to typically developing peers (e.g., daytime sleepiness; n = 5, SMD = 0.54, p = .01). Only few studies objectively measured sleep and no significant differences were found between both groups (n = 3) in any parameter. Differences in sleep hygiene could not be examined due to a limited number of studies. Conclusions: Adolescents with ADHD report significantly worsened subjectively sleep parameters and more sleep problems compared to controls. These findings are still preliminary as a limited number of studies was identified. Nevertheless, it is advised to routinely include sleep assessment in the ADHD diagnostic process. More research is needed with a focus on objective measurement and sleep hygiene in ADHD.

RESUMO

OBJECTIVE: This study examined the effect of COVID-19 restrictions on the sleep and sleep hygiene of adolescents with ADHD and comorbid sleep problems and neurotypical adolescents (NT). METHOD: Four groups (two ADHD and two NT) of in total 100 adolescents (50 ADHD and 50 NT) were included. One ADHD and NT group were tested during many COVID-19 restrictions, the other during few. MANCOVAs were implemented with ADHD diagnosis and level of COVID-19 restrictions as independent and sleep outcomes (subjective and objective total sleep time (TST) and sleep onset latency (SOL), sleep and sleep hygiene problems) as dependent variables. RESULTS: Both groups had a shorter objective TST during the week during many COVID-19 restrictions. Furthermore, adolescents with ADHD had a shorter subjective SOL during the weekend when there were many COVID-19 restrictions, while the SOL of the NT group stayed the same. CONCLUSION: COVID-19 restrictions are related to the sleep of adolescents with and without ADHD. However, causality and underlying mechanisms need further investigation.

RESUMO

INTRODUCTION: Although youth-friendly service characteristics have been previously identified, consensus among a representative group of stakeholders about which of these characteristics are truly relevant to the youth-friendliness of services is currently lacking. In our study, young adults, parents and professionals were consulted on this topic to reveal existing (dis)agreement. In addition, (dis)agreement on feasibility for implementation in clinical practice was also assessed. METHODS: A mixed-method Delphi approach was used with three online questionnaire rounds and a physical meeting. Young adults (18-26 years) and parents were part of a public panel and professionals were allocated to the professional panel. In the rounds, participants were asked to rate the importance and feasibility of each item. Subsequently, the percentage agreement (% of participants giving a score of 7 or above on a 9-point Likert scale) within and across panels was calculated. Consensus was assumed to have been reached when at least 70% agreement was achieved. A thematic analysis of the qualitative data, obtained in the rounds and the physical meeting, was performed to identify overarching themes and characteristics of relevance to the youth-friendliness of services. RESULTS: For 65% of the items included in the Delphi questionnaire, consensus on importance was reached within both panels. Participants showed more insecurity about the feasibility of these items, however. Our thematic analysis revealed reasons for disagreement between and within the panels. CONCLUSIONS: Our study revealed substantial between- and within-panel agreement on youth-friendly service characteristics. We recommend that the items for which consensus was reached should be used as a checklist in terms of youth mental health service development, design and delivery. The characteristics for which there was disagreement between and within the panels should inspire an ongoing trialogue between young adults, parents and professionals both on the individual level and the service level. PATIENT OR PUBLIC CONTRIBUTION: In this study, (parents of) young adults with lived experience were included as experts, including one of the coauthors. This coauthor contributed to the manuscript by having a final say about the included quotes.

RESUMO

Informed consent and debriefing of research participants in studies that use deception are ethical safeguards for which existing scholarly work on their implementation remains variable and insufficiently clear. A systematic review of research ethics guidelines was conducted to sketch a picture of whether, why and how informed consent and debriefing are recommended when using deception. Documents roughly agreed on several general principles, but varied significantly in the specifics of why and whether these safeguards are necessary, in which conditions and how they should be implemented. Various aspects that appear in the literature could not be found in the guidelines. In our review, guidance was integrated and showed a variation of implementation strategies that could help in contextualizing these safeguards.

RESUMO

INTRODUCTION: Adolescents with attention deficit hyperactivity disorder (ADHD) experience a more disrupted sleep and more sleep problems compared with typically developing adolescents. This is particularly concerning, because disrupted sleep is related to worsened clinical, neurocognitive and functional outcomes and leads to increased ADHD symptom impairment. Due to the specific difficulties adolescents with ADHD experience, a tailored sleep treatment is needed. Therefore, our lab developed a cognitive behavioural treatment-Sleep IntervEntion as Sympom Treatment for ADHD (SIESTA)-that integrates sleep training with motivational interviewing, and planning/organisational skills training with the aim of improving sleep problems in adolescents with ADHD. METHODS AND ANALYSIS: A randomised, controlled, investigator-blinded monocentre trial is used to test whether SIESTA in combination with treatment as usual (TAU) for ADHD results in greater improvement in sleep problems than TAU only. Adolescents (aged 13-17 years) with ADHD and sleep problems are included. They complete measurements before treatment (pre-test), approximately 7 weeks after the pre-test (post-test), and approximately 3 months after the post-test (follow-up). The assessment includes questionnaires filled out by adolescents, parents and teachers. Additionally, sleep is assessed by actigraphy and sleep diaries at all time-points. Primary outcomes include objectively and subjectively measured sleep architecture (specified as total sleep time, sleep onset latency, sleep efficiency and number of awakenings), subjectively measured sleep problems and sleep hygiene. Secondary outcomes include ADHD symptoms, comorbidities and functional outcomes. To analyse the data, a linear mixed effects model will be used with an intent-to-treat approach. ETHICS AND DISSEMINATION: The study activities, informed consent and assent forms have been approved by the Ethical Committee Research UZ/KU Leuven (study ID S64197). If proven effective, the intervention will be implemented throughout Flanders. Therefore, an advisory board consisting of societal partners in healthcare is appointed at the start of the project, giving advice throughout the project and assistance with implementation afterwards. TRIAL REGISTRATION NUMBER: NCT04723719.

RESUMO

BACKGROUND: One of the COVID-19 pandemic consequences that has affected families the most is school lockdowns. Some studies have shown that distance learning has been especially challenging for families with a child with neurodevelopmental disorders such as ADHD or ASD. However, previous studies have not taken the heterogeneity of these disorders into account. The aim of the present study was therefore to investigate differences between families with a child with ADHD, ASD, or both conditions, and to examine the role of underlying deficits in executive functioning (EF) in both children and parents in relation to negative and positive effects of distance learning. METHODS: Survey data assessing both negative and positive experiences of distance learning were collected from parents with a child aged 5-19 years in seven Western European countries: the UK, Germany, Spain, Sweden, the Netherlands, Italy, and Belgium. Altogether, the study included 1010 families with a child with ADHD and/or ASD and an equally large comparison group of families with a child without mental health problems. We included measures of three different types of negative effects (i.e., effects on the child, effects on the parent, and lack of support from school) and positive effects on the family. RESULTS: Results confirmed that families with a child with ADHD, ASD or a combination of ADHD and ASD showed higher levels of both negative and positive effects of distance learning than the comparison group. However, few differences were found between the clinical groups. Group differences were more pronounced for older compared to younger children. Regarding the role of both ADHD/ASD diagnosis and EF deficits, primarily children's EF deficits contributed to high levels of negative effects. Parent EF deficits did not contribute significantly beyond the influence of child EF deficits. Families of children with ADHD/ASD without EF deficits experienced the highest levels of positive effects. CONCLUSIONS: School closings during COVID-19 have a major impact on children with EF problems, including children with neurodevelopmental disorders. The present study emphasizes that schools should not focus primarily on whether a student has a neurodevelopmental disorder, but rather provide support based on the student's individual profile of underlying neuropsychological deficits.

RESUMO

Research participants are often deceived for methodological reasons. However, assessing the ethical acceptability of an individual study that uses deception is not straightforward. The academic literature is scattered on the subject and several aspects of the acceptability assessment are only scarcely addressed, which parallels reports of inconsistent ethics review. Therefore, we aimed to investigate where normative guidance documents agree and disagree about this assessment. A PRISMA-Ethics-guided systematic review of normative guidance documents that discuss deception of research participants was conducted. Our search strategy resulted in 55 documents that were subsequently analyzed through abductive thematic analysis. While guidance documents mention little about specific risks and opportunities of deception, our analysis describes a rich picture of the thresholds for acceptability of the risks and benefits of deception and their integration, the comparison with the risk-benefit analysis of alternative non-deceptive methods, and the bodies of people who are positioned to do the review. Our review reveals an agreement on the general process of assessing the acceptability of studies that use deception, although significant variability remains in the details and several topics are largely or completely unaddressed in guidance documents.

RESUMO

The aim of the present study was to examine parental experiences of homeschooling during the COVID-19 pandemic in families with or without a child with a mental health condition across Europe. The study included 6720 parents recruited through schools, patient organizations and social media platforms (2002 parents with a child with a mental health condition and 4718 without) from seven European countries: the UK (n = 508), Sweden (n = 1436), Spain (n = 1491), Belgium (n = 508), the Netherlands (n = 324), Germany (n = 1662) and Italy (n = 794). Many parents reported negative effects of homeschooling for themselves and their child, and many found homeschooling to be of poor quality, with insufficient support from schools. In most countries, contact with teachers was limited, leaving parents with primary responsibility for managing homeschooling. Parents also reported increased levels of stress, worry, social isolation, and domestic conflict. A small number of parents reported increased parental alcohol/drug use. Some differences were found between countries and some negative experiences were more common in families with a child with a mental health condition. However, differences between countries and between families with and without a mental health condition were generally small, indicating that many parents across countries reported negative experiences. Some parents also reported positive experiences of homeschooling. The adverse effects of homeschooling will likely have a long-term impact and contribute to increased inequalities. Given that school closures may be less effective than other interventions, policymakers need to carefully consider the negative consequences of homeschooling during additional waves of the COVID-19 pandemic and future pandemics.

RESUMO

Executive functions (EF) and self-regulation (SR) are fundamental for children's learning, school functioning and academic achievement. EF/SR fail to develop to its full potential if contextual stimulation is not adequately presented. This is evident in the training programmes directly and exclusively targeting EF/SR stimulation, which lack durable and transferable effects. Therefore, recent research has shifted the attention towards malleable environmental factors; more specifically, to the role of school and classroom environment as an important developmental context for promoting children's EF/SR skills and, in turn, their cognition and behaviour. Numerous observational studies have shown a correlation between the quality of teacher-student relationship (TSR) at the dyadic level or teacher-student interaction (TSI) at the classroom level and children's EF/SR skills. To explore the direction of this association, the objective of this systematic literature review was to examine the causal effect of experiments and interventions that aim to improve children's EF/SR by manipulating the TSI. Overall, the results from 18 included studies indicated that children in treatment groups show higher gains, albeit small-sized, in EF/SR performance compared to controls. Furthermore, TSI manipulation seemed to affect children's SR skills more strongly than children's EF skills. More importantly, the findings revealed the largest effects of these manipulations in children considered vulnerable or disadvantaged, suggesting that the cognitive deficits can be minimised if these children are supported appropriately. Given high study heterogeneity, this review highlights the need for more research (and interventions) explicitly investigating TSI and TSR and their potential impact on EF and SR in children. This study aims to provide information as to which specific aspects need to be examined more closely, instructing further development and implementation of efficient and effective interventions in education.

RESUMO

As the Inventory of Dimensions of Emerging Adulthood (IDEA) was developed to assess features of emerging adulthood, international differences have been observed between emerging adults over the world. To assess the IDEA's applicability to emerging adults in Flanders, a Dutch translation was administered to 489 participants between 17 and 26 years old, and exploratory and confirmatory factor analyses were performed. Important latent factors in the version used in the United States of America, such as focus on others, were not observed. Four subscales were created to reflect psychological features of our sample, combining elements of both Arnett's theory of emerging adulthood and neo-Eriksonian theories of identity development. A new subscale, reflecting commitment and responsibility, was more present in older participants and employed participants, and associated with well-being. Finally, results suggested that employment, as well as place of residency, and romantic relationships significantly influence psychological development during young adulthood.

RESUMO

OBJECTIVE: Recently, research indicated that extended examination duration was perceived as effective by students with ADHD. However, the objective effectiveness of this accommodation has not been researched extensively. This study addresses this gap in literature. METHOD: A total of 30 students with ADHD and 30 matched typically developing controls (TDC) participated in a simulation of a real-life examination. They filled in three parallel versions of a paper-and-pencil test in three time conditions: 1 hr (+0%), 1 hr 20 min (+33%), and 1 hr 30 min (+50%). RESULTS: When granted extended examination duration, students with ADHD and TDC use extra time but their performance does not increase. In addition, test-taking strategies were altered to a limited extent, and strategies that are perceived as effective (e.g., marking key words) were rarely used by the students. CONCLUSION: It is concluded that extended examination duration is not objectively effective in an experimental design. Limitations and guidelines for future research are formulated.

RESUMO

Adolescence is characterized by considerable changes in cognitive and socio-emotional skills. There are considerable differences between adolescents with regards to the development of these skills. However, most studies examine adolescents' average functioning, without taking into account this heterogeneity. The current study applies network analysis in order to examine heterogeneity of cognitive and socio-emotional functioning in adolescents on-track or delayed in their school progression. Data was collected at two time-points for on-track (n = 320) and delayed (n = 69) adolescents (Mage = 13.30 years, SDage = 0.77). Repeated measures ANOVA showed no significant differences between the groups in cognitive and socio-emotional functioning (p's > 0.05). Network analysis revealed that executive functions play a key role in the network of cognitive, social, and emotional functioning. This is especially the case in the delayed group where executive functions are even more central, both at T1 (inhibition and shifting) and T2 (shifting). Subsequent community analysis revealed three profiles in both groups: a well-adapted and well-balanced group, a group with high levels of need for arousal and risk-taking, and a group with regulation problems. Compared to on-track adolescents, delayed adolescents showed even higher levels of risk-taking in the second profile and higher levels of executive function problems in the third profile at T1. These differences were leveled out at T2, indicating adolescents in the delayed group catch up with their peers. This study highlights the intricate balance between cognitive, social and emotional functioning in adolescents in relation to school performance and provides preliminary evidence of the importance of taking individual differences within groups into account.

RESUMO

Although research shows that young adults with autism spectrum disorder (ASD) struggle with higher rates of depression, anxiety, and other co-occurring psychiatric disorders, their psychological development through emerging adulthood remains understudied. To explore relevant developmental themes for young adults with ASD while subscribing to a social-constructionist epistemology, we interviewed young adults with ASD and their mental health care professionals individually, and organized focus groups with their parents in a multiperspective design. Developmental themes were identified using interpretative phenomenological analysis. Despite a substantial body of research considering lack of social motivation, a central ASD characteristic, narratives were remarkably socially oriented. This article discusses the overarching themes of (a) searching for balance and negotiating ASD and (b) searching for suitable surroundings in different areas of life, as well as their implications for clinical practice.

RESUMO

Working memory, used to temporarily store and mentally manipulate information, is important for children's learning. It is therefore valuable to understand which (contextual) factors promote or hinder working memory performance. Recent research shows positive associations between positive parent-child and teacher-student interactions and working memory performance and development. However, no study has yet experimentally investigated how parents and teachers affect working memory performance. Based on attachment theory, the current study investigated the role of parent and teacher emotional support in promoting working memory performance by buffering the negative effect of social stress. Questionnaires and an experimental session were completed by 170 children from grade 1 to 2 (Mage = 7 years 6 months, SD = 7 months). Questionnaires were used to assess children's perceptions of the teacher-student and parent-child relationship. During an experimental session, working memory was measured with the Corsi task backward (Milner, 1971) in a pre- and post-test design. In-between the tests stress was induced in the children using the Cyberball paradigm (Williams et al., 2000). Emotional support was manipulated (between-subjects) through an audio message (either a weather report, a supportive message of a stranger, a supportive message of a parent, or a supportive message of a teacher). Results of repeated measures ANOVA showed no clear effect of the stress induction. Nevertheless, an effect of parent and teacher support was found and depended on the quality of the parent-child relationship. When children had a positive relationship with their parent, support of parents and teachers had little effect on working memory performance. When children had a negative relationship with their parent, a supportive message of that parent decreased working memory performance, while a supportive message from the teacher increased performance. In sum, the current study suggests that parents and teachers can support working memory performance by being supportive for the child. Teacher support is most effective when the child has a negative relationship with the parent. These insights can give direction to specific measures aimed at preventing and resolving working memory problems and related issues.

RESUMO

BACKGROUND: The current study investigates how children's amount of daily physical activity relates to subcomponents of executive functions, the cognitive processes needed for goal-directed behavior. Previous studies rarely determined this association at the subcomponent level and did not explicitly examine the period when children make the transition to first grade, despite its importance for the development of executive functions. METHODS: In a sample of 54 children, working memory, inhibition, and cognitive flexibility were thoroughly measured at the subcomponent level at the end of kindergarten and first grade. In the middle of first grade, children wore a pedometer for 7 consecutive days. RESULTS: Regression analyses showed that performance on a measure of the visuospatial sketchpad, the central executive, and fluency was predicted by children's amount of daily physical activity after controlling for initial task performance. CONCLUSIONS: The development of the visuospatial sketchpad (working memory), the central executive (working memory), and fluency (cognitive flexibility) might be improved by increasing the amount of time being physically active. However, as other subcomponents of executive functioning were not affected, the role of other aspects of physical activity, such as intensity and content, in the development of executive functions should be further investigated.

RESUMO

Executive functioning (EF), needed for goal-oriented behaviour, thoughts, and emotions, is important for various life domains. This study examined the relationship between family demographics and EF subcomponents. A kindergarten sample was tested on subcomponents of working memory, inhibition, and cognitive flexibility. Parents provided information on demographic variables. For 78 children both EF and demographic data were available. First, demographic profiles were identified within the sample. Two profiles were found: A low-risk profile of mainly two-biological-parent, high-income families with a highly educated mother who did not smoke during pregnancy and a high-risk profile of low-income families with a young, low-educated mother who more often smoked during pregnancy. Second, children with different demographic profiles were compared on EF subcomponents. Results indicate differential relations between family demographics and EF subcomponents: Whereas for most EF subcomponents no association with family demographics was found, high-risk children performed better on response shifting and tended to perform worse on verbal memory than low-risk children. Parenting stress decreased performance only for high-risk children. Although this study found limited impact of family demographics for EF, further longitudinal research can provide nuanced insights about which factors influence specific EF subcomponents during which developmental periods and guide targeted prevention of EF difficulties.
