Background: ADHD is highly prevalent in adolescents. ADHD is characterized by heightened impulsive behavior and is often associated with increased risk-taking behavior in adolescence. Previous research has mostly focused on negative aspects of risk-taking behavior. However, recently two other types of risk-taking behavior have been identified:…

The purpose of this study was to investigate the self-perception bias (SPB) in adolescents with attention-deficit hyperactivity disorder (ADHD). The SPB was defined as adolescent underestimation of their learning and behavior problems in comparison to parent- or teacher-reports or a standardized achievement test. The sample comprised 74…

This paper examined the effects of training in creative problem-solving on intelligence. We revisited Stankov's report on the outcomes of an experiment carried out by R. Kvashchev in former Yugoslavia that reported an IQ increase of seven points, on average, across 28 tests of intelligence. We argue that previous analyses were based on a…

This study shows that residual variation can cause problems related to scaling in exponential random graph models (ERGM). Residual variation is likely to exist when there are unmeasured variables in a model--even those uncorrelated with other predictors--or when the logistic form of the model is inappropriate. As a consequence, coefficients cannot…

The purpose of this study was to identify predictors of friendship quality in adolescents with and without ADHD. The participants were 115 adolescents (61 ADHD, 54 non-ADHD), ages 13-18. The adolescents completed questionnaires assessing the quality of their relationships with their best friends, social perspective taking, anxiety and depression.…

The present study intended to examine the impact of an activity-based intervention on the attitude and awareness of adolescents towards sustainability and its dimensions using a quasi-experimental research design. A cluster sample of 99 participants, experimental and control groups comprising of 50 and 49 school students, was selected for the…

Concerns have been expressed about the long term inclusion of students with social, emotional and mental health difficulties in mainstream education. Often, this results in continuous referrals with alternative provision. Whilst student views have been explored, there has been a lack of research focusing on perspectives within Primary education.…

The purpose of this study was to investigate sex differences in behavioral and emotional problems in high-functioning girls and boys with autism spectrum disorder. The results obtained by adolescents with autism spectrum disorder were compared with those of typically developing girls and boys. Correlations between parents' and adolescents' ratings…

The main objective of this study was to explore the associations between character strengths and internalising and externalising problems. One thousand, one hundred thirty-eight adolescents, completed the 96-item VIA Inventory of Strengths for Youth, Youth Self Report, and Brief Symptom Inventory. Using latent class analysis, we extracted six…

Difficulty with communication and social functioning are two outstanding core symptoms of autism spectrum disorder, and physical activity has long been suggested to improve autism spectrum disorder symptoms. In this meta-analysis of controlled trials, we examined the effects of physical activity interventions compared to controls on communication…

Using a systematic search strategy in which intellectual giftedness was operationalized in terms of IQ score, the authors examined evidence from studies reporting on associations between this aspect of giftedness and psychopathology. A total of 18 studies met the inclusion criteria: compared gifted (IQ = 125) and nongifted (IQ = 90-110) peers or…

Despite the prevalence of studies showing increased stress among mothers of individuals with autism spectrum disorders, few studies have examined general stress among typically developing siblings. This study used an online survey to compare the levels of self-reported stress between adolescent siblings of individuals with autism spectrum disorder…

Background: Borderline personality symptoms include emotional dysregulation, high levels of impulsivity leading to self-harm and suicidality, an unstable sense of self, fears of abandonment, extremely turbulent relationships, and psychic pain. They are considered to disrupt normative adolescent development however their unique contribution to…

We asked: "What are the similarities and differences in mathematical processing associated with solving learning-based and insight-based problems?" To answer this question, the ERP research procedure was employed with 69 male adolescent subjects who solved specially designed insight-based and learning-based tests. Solutions of…

There is considerable variability in the extent to which young people with developmental language disorder (DLD) experience mental health difficulties. What drives these individual differences remains unclear. In the current article, data from the Twin Early Development Study were used to investigate the genetic and environmental influences on…
