BACKGROUND: In 2013, Internet gaming disorder (IGD) was incorporated in the current version of the DSM-5. IGD refers to a problematic use of video games. Longitudinal studies on the etiology of IGD are lacking. Furthermore, it is currently unclear to which extent associated psychopathological problems are causes or consequences of IGD. In the present survey, longitudinal associations between IGD and adolescent and parental mental health were investigated for the first time, as well as the temporal stability of IGD. METHODS In a cross-lagged panel design study, family dyads (adolescent with a parent each) were examined in 2016 (t1) and again 1 year later (2017, t2). Overall, 1095 family dyads were assessed at t1 and 985 dyads were re-assessed at t2 with standardized measures of IGD and several aspects of adolescent and parental mental health. Data were analyzed with structural equation modeling (SEM). RESULTS Male gender, a higher level of hyperactivity/inattention, self-esteem problems and IGD at t1 were predictors of IGD at t2. IGD at t1 was a predictor for adolescent emotional distress at t2. Overall, 357 out of the 985 adolescents received a diagnosis of IGD at t1 or t2: 142 (14.4%) at t1 and t2, 100 (10.2%) only at t1, and 115 (11.7%) only at t2. CONCLUSIONS Hyperactivity/inattention and self-esteem problems seem to be important for the development of IGD. We found first empirical evidence that IGD could prospectively contribute to a deterioration of adolescent mental health. Only a subgroup of affected adolescents showed IGD consistently over 1 year.

Evidence suggests that maternal care constitutes a protective factor for psychopathology which may be conditional on the level of family adversity. Given that psychopathology is frequently linked with social deficits and the amygdala with social functioning, we investigated the impact of early maternal care on amygdala function under high vs low familial risk for psychopathology. Amygdala activity and habituation during an emotional face-matching paradigm was analyzed in participants of an epidemiological cohort study followed since birth (n = 172, 25 years). Early mother-infant interaction was assessed during a standardized nursing and play setting at the age of three months. Information on familial risk during the offspring's childhood and on the participants' lifetime psychopathology was obtained with diagnostic interviews. An interaction between maternal stimulation and familial risk was found on amygdala habituation but not on activation, with higher maternal stimulation predicting stronger amygdala habituation in the familial risk group only. Furthermore, amygdala habituation correlated inversely with Attention Deficit Hyperactivity Disorder (ADHD) diagnoses. The findings underline the long-term importance of early maternal care on the offspring's socioemotional neurodevelopment and of interventions targeting maternal sensitivity early in life, particularly by increasing maternal interactive behavior in those with familial risk.

Teacher's evaluation of students is sometimes negatively affected by diagnostic labels. We explored such negative effects caused by the labels \"dyscalculia\", \"dyslexia\", and \"ADHD\" in teacher students. In Experiment 1, we varied the presence of the dyscalculia and dyslexia label in vignettes between participants. The dyslexia but not the dyscalculia label had a negative effect on participant's academic expectations. In our preregistered Experiment 2, the presence of the ADHD label in vignettes was manipulated within participants. To understand the cognitive mechanisms driving label effects, we explored participants' attributions regarding the students' problems. Furthermore, a short dissonance-based intervention for counteracting negative label effects was implemented. Unexpectedly, we found both negative and positive label effects. The label led to more positive performance expectations and to more negative ratings of problem stability and problem control. The dissonance-based intervention led to more positive evaluations regardless of whether the ADHD label was mentioned or not. Overall, our findings suggest that learning-disorder labels affect teachers' expectations in different ways. (ZPID).

Background: We aimed to determine the associations between breastfeeding and children's neurodevelopment indexed by intelligence quotient (IQ) and emotional and behavioural problems through mid-childhood adjusting for prenatal and postnatal depression and multiple confounders; and to test the novel hypothesis that breastfeeding may moderate the effects of prenatal depression and anxiety on children's neurodevelopment. Methods: The study is based on women and their children from the longitudinal Avon Longitudinal Study of Parents and Children (n=11,096). Children's IQ was derived from standardized in-person testing; behaviour problems were assessed according to parent-report; information on breastfeeding, prenatal depression and anxiety and multiple confounders were derived from self-report questionnaires. We conducted hierarchical multiple regression adjusting for several covariates. Results: 43% women were exclusively breastfeeding at 1 month and an additional 16.8% were engaged in mixed or partial breastfeeding. Both exclusive breastfeeding (B = 2.19; SD = 0.36, p =.00) and mixed feeding (B = 1.59; SD= 0.52; p=.00) were positively associated with IQ at 8 years of age, after adjusting for covariates. Exclusive breastfeeding was negatively associated with hyperactivity/attention deficit at 4 years (B = -.30, SD = .05; p ( .01); mixed feeding was related to hyperactivity/attention deficit at age 9 (B = .20; SD = .08; p = .03) after adjustments. There was no association between breastfeeding and emotional or conduct problems. Breastfeeding did not moderate the association between prenatal depression and anxiety and children's neurodevelopment. Conclusions: The selective association between breastfeeding and neurodevelopmental measures suggests a nutritional rather than broader beneficial psychological effect on child neurodevelopment. Breastfeeding did not moderate the associations between prenatal depression and anxiety and child neurodevelopment, suggesting separate mechanisms of action. (ZPID).

Students with attention deficit/hyperactivity disorder (ADHD) show reduced on-task behavior at school and educational problems due to the symptoms associated with this diagnosis. Classroom management strategies (CMS) are important to reduce impairment due to ADHD symptoms but are not yet well implemented. In this study we analyzed whether the facilitators and barriers regarding the intention to apply CMS identified for pre-service teachers are replicable in a sample of teachers in service. Overall, 599 teachers in service completed an online survey on the intention to apply CMS, their attitude towards CMS and towards students with ADHD, direct experiences, individual differences, and social influences. We calculated path models that significantly clarified variance in the intention to apply CMS (R-intention to use effective CMS(2) = 0.47, p ( 0.01 and R-intention to use ineffective CMS(2) = 0.39, p ( 0.01). It turns out that similar variables are relevant to teachers in service as well as pre-service teachers. A models' extension to include variables that do justice to the difference between the two groups, such as work experience, shows a better model fit. Especially, attitude towards CMS, attitude towards students with ADHD, strain, perceived behavioral control and teachers' affiliation with primary or special needs schools are important variables regarding the intention to apply CMS. The implementation of effective and elimination of ineffective CMS should thus be addressed by targeting teacher's attitudes towards children with ADHD. Furthermore, strain prevention and education might enhance the application of effective CMS. (ZPID).

Students with attention-deficit/hyperactivity disorder (ADHD) often experience school-related difficulties. Although evidence-based classroom management strategies (CMS) are known to alleviate such problems, they are rarely implemented. The current study examined whether a path model including variables influencing the use of effective CMS developed by top-down methods can be replicated utilizing an open science method. An extended model including class size and experience with children with ADHD was also calculated. We further explored prominent implementation barriers. N = 336 in-service teachers completed an online survey. Perceived effectiveness, training on ADHD, perceived disruption, and affiliation with primary/special educational needs schools were important variables associated with the use of CMS. While class size was not correlated with the use of CMS, experience mediated by training revealed an indirect association with it. Class size, lack of time, and many students with disabilities were the most frequently reported implementation barriers. The implementation of effective CMS could thus be mainly enhanced by improving how effectiveness is perceived and by engaging teachers in ADHD-specialized training. Preparing teachers in how to cope with potential barriers should also be considered. (ZPID).

Children with attention deficit hyperactivity disorder (ADHD) often exhibit comorbid specific learning disorders. In clinical samples, comorbidity in girls with ADHD tends to be more common than in boys with ADHD. However, this is not the case in studies of random samples. In this paper gender differences in the comorbidity of ADHD symptoms and learning disorders in reading, spelling and math are explored in a population-based sample of 2605 3rd and 4th graders (1304 girls) without symptoms of ADHD and 415 (141 girls) with symptoms of ADHD. Girls with ADHD symptoms had higher ratios of comorbid math disorders than boys with ADHD symptoms, but not with reading or spelling disorders. Math achievement was predicted by gender and by symptoms of inattention. Girls with ADHD symptoms and math disorders received the same amount of additional support from teachers or therapists as boys with ADHD symptoms and math disorders. Our results highlight the importance of exploring the increased comorbidity of specific learning disorders in children with ADHD symptoms and especially with math disorders in girls with ADHD symptoms. Implications for providing suitable interventions and preventing the accumulation of academic problems are discussed. (DIPF/Orig.).

Drawing on communities of practice and social cognitive learning theories, this paper explores language teachers' beliefs, knowledge and practices concerning the provision of high-quality education to learners with specific learning difficulties in various educational settings around the world. The data sample for this paper comprises qualitative data (video-recorded interviews and teaching resources) collected from six teachers working across various educational settings (primary, secondary, college and university) across several geographical areas (Europe, Middle East, and Southeast Asia). Thematic analysis was adopted to analyse the data. The findings suggest that teachers continue to experience challenges in educating learners with specific learning difficulties regardless of the educational setting. Limited opportunities for receiving specialised training in this area have been identified by several teachers as one of the key factors affecting the quality of their practice. The change in the mode of instruction from face-to-face to online was not always reported as negatively affecting the quality of educational provision to learners with specific learning difficulties. Technology-assisted online lesson delivery was seen as being advantageous to learners with some types of learning difficulties. Findings from this paper can be useful to teacher-practitioners and teacher-educators who are interested in improving the quality of language education for learners with specific learning difficulties.

Students with administrative care measures have historically faced difficulties in achieving school goals. The Covid-19 pandemic forced the declaration of a lockdown, which accelerated changes in the schools' pedagogical actions. This investigation analyses the strategies used by the educational system to promote the academic inclusion of students who have an open protection file in the child welfare system within the context of Covid-19. Two different phases are compared: Phase 1) from the March lockdown to the end of the 2019/20 school year; Phase 2) The first six weeks of the beginning of the 2020/21 school year. Longitudinal follow-ups were carried out with adolescents in care with a sample of N = 10 (Phase 1) and N = 11 (Phase 2). Based on the grounded theory, information is supplemented by case studies through interviews with educational professionals, N = 14 (Phase 1) and N = 11 (Phase 2). The results indicate deficits of schools' adaptability to the situation of the students suffering social exclusion and difficulties in monitoring when students do not attend school in person and do school activities at home. It is concluded that the design of the educational policy applied in the context of the pandemic does not take the social factor into account. (DIPF/Orig.).
