Since the outbreak of the COVID-19 pandemic, increases in suicidal ideation and suicide attempts in adolescents have been registered. Many adolescents experiencing suicidal ideation turn to online communities for social support. In this retrospective observational study, we investigated the communication—language style, contents and user activity—in 7975 unique posts and 51,119 comments by N = 2862 active adolescent users in a large suicidal ideation support community (SISC) on the social media website reddit.com in the onset period of the COVID-19 pandemic. We found significant relative changes in language style markers for hopelessness such as negative emotion words (+ 10.00%) and positive emotion words (− 3.45%) as well as for social disengagement such as social references (− 8.63%) and 2nd person pronouns (− 33.97%) since the outbreak of the pandemic. Using topic modeling with Latent Dirichlet Allocation (LDA), we identified significant changes in content for the topics Hopelessness (+ 23.98%), Suicide Methods (+ 17.11%), Social Support (− 14.91%), and Reaching Out to users (− 28.97%). Changes in user activity point to an increased expression of mental health issues and decreased engagement with other users. The results indicate a potential shift in communication patterns with more adolescent users expressing their suicidal ideation rather than relating with or supporting other users during the COVID-19 pandemic.

The purpose of this study was to test child and adolescent psychosocial and psychopathological risk factors as predictors of adult criminal outcomes in a Swiss community sample. In particular, the role of active and avoidant problem coping in youths was analysed. Prevalence rates of young adult crime convictions based on register data were calculated. Univariate and multivariate logistic regressions were used to analyse the prediction of adult criminal convictions 15years after assessment in a large Swiss community sample of children and adolescents (n=1,086). Risk factors assessed in childhood and adolescence included socio-economic status (SES), migration background, perceived parental behaviour, familial and other social stressors, coping styles, externalizing and internalizing problems and drug abuse including problematic alcohol consumption. The rate of any young adult conviction was 10.1%. Besides externalizing problems and problematic alcohol consumption, the presence of any criminal conviction in young adulthood was predicted by low SES and avoidant coping even after controlling for the effects of externalizing problems and problematic alcohol use. The other predictors were significant only when externalizing behaviours and problematic alcohol use were not controlled. In addition to child and adolescent externalizing behaviour problems and substance use, low SES and inadequate problem-solving skills, in terms of avoidant coping, are major risk factors of young adult criminal outcomes and need to be considered in forensic research and criminal prevention programs.

The study investigated the predictive value of pro-social behaviour for developmental pathways of behavioural and emotional problems at kindergarten age. One hundred and sixty children participated in the study at the ages of 5 and 6. Teachers and parents completed the Strengths and Difficulties Questionnaire; children completed the Berkeley Puppet Interview at both assessment points. Single-informant data were aggregated to enhance the reliability and validity of data. Gender and parental educational status were controlled. Symptoms (conduct problems, hyperactivity and emotional symptoms) and pro-social behaviour were moderately stable over time. Compared to girls, boys showed higher levels and increases of conduct problems and hyperactivity and lower levels of pro-social behaviour. Lower parental educational level was associated with higher levels and increases in hyperactivity. Although pro-social behaviour was cross-sectionally associated with behavioural and emotional symptoms, pro-social behaviour did not predict changes in conduct problems or hyperactivity over time. However, children with above average emotional symptoms and above average pro-social behaviour at Age_5 showed the highest level of emotional symptoms at Age_6. The results indicate that low levels of pro-social behaviour are associated with children’s externalising behaviour problems, but that for children with high levels of emotional symptoms, higher levels of pro-social behaviour should also be considered as a risk factor. In sum, our results suggest mainly homotypic pathways of internalising and externalising symptoms across kindergarten age, but indicate that the assessment of pro-social behaviour yields additional information regarding the developmental pathways of emotional symptoms.

Background: The study of biological and psychosocial risk factors for the development of emotional and behavioural problems in children of drug-dependent mothers. Methods: In a sample of 52 children and drug-dependent mothers participating in a residential intervention programme emotional and behavioural problems were studied in the children by use of the Child Behaviour Checklist (CBCL). The Symptom-Checklist Revised (SCL-90-R) served to assess mental problems in the mother. Drug exposure during pregnancy, various psychosocial risk factors due to the drug-career, and educational status of the mother were assessed by maternal interview. A brief assessment of intelligence of the mother was included. Results: Among the various biological and psychosocial risk factors, maternal mental health problems, maternal educational status, and a small number of close social relationships correlated significantly with child outcome variables. Multiple regression analyses identified maternal mental health factors as the main predictors of child behaviour. Conclusions: Assisting drug-dependent mothers in overcoming the psychosocial sequelae of drug abuse implies also assistance to the children in terms of prevention of emotional and behavioural problems

Given the stubborn phenomenon of many children's serious difficulties and failure in mathematical learning, the hypothesis of developmental delay, or neurocognitively based deficiency should be complemented by further explanantions of children's weaknesses and substandard performance in mathematics. One obvious explanantion is that schooling and instruction for low ability children and for children with special needs is often inadequate. The present contribution examines selected research on mathematics learning under a cognitive instructional (didactical) perspective. Constructivist learning theory, the rooting of meaningful learning in concrete modeling activities, the balancing of understanding and practice in mathematics instruction, diagnostic and adaptive teaching, computer-assisted instruction, and the role of nonmathematical stumbling-blocks are discussed as principles and factors of effective mathematics learning and teaching.

This case report presents a thirteen year-old boy who was diagnosed as having Hypomelanosis of Ito. The developmental history includes severe failure to thrive, and moderate atypical autism as well as diverse clinical and neuropsychological symptoms are present. The pattern of neuropsychological functioning, which can be partially related to the neurophysiological findings, is discussed within the context of existing neuropsychological theories about autistic disorders.

In an epidemiological sample of children aged 6 to 17 a total of 1964 parents responded to the Child Behavior Check List (CBCL). A subgroup of 399 parents were interviewed with the Diagnostic Interview Schedule for Children (DISC). The mean syndrome scale scores in the various sex/age groups were in the lower range of several international studies using the CBCL. Effect analyses revealed sex to be more important than nationality (indigenous vs. immigrant) and age. All effects had to be considered as being small. Convergence between syndrome scales of the CBCL and interview-derived DSM-III-R diagnoses was good for three major groups of disorders.

The family history was studied in children with elective mutism. The samples comprised a series of N = 38 children with elective mutism and a control group of N = 31 children with a similar behavioural phenotype, i.e., the combination of an emotional disorder and a developmental disorder of articulation or expressive language. Interviews were performed with the respective mothers. There was a clear excess of the personality trait of taciturnity in first-, second-, and third-degree relatives. Although mutism was reported almost exclusively in the group of relatives of children that manifested elective mutism, the differences between the two samples were not significant probably due to low frequencies. Disorders of speech and language were quite common in the relatives of subjects in both samples. Psychiatric disorders were more frequently reported in the families with an electively mute child. The study lends some evidence for the assumption that genetic factors may play a role in the etiology of elective mutism.
