Adolescence is a period of social, psychological, and physiological change, including the onset of puberty. Differential pubertal onset has been linked to a myriad of problems, including mental health problems. Therefore, we aim to investigate deviating pubertal development in autism, and whether this is more pronounced in girls than in boys. A total of 68 individuals (nASC = 34, nCOM (comparisons) = 34) aged 12 to 16 years were ...

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 ...

Children with ADHD are theorized to experience increased negative emotional responses to punishment, compared to typically developing (TD) children, resulting in altered behavioral responding (Amsel, 1992). However, this has not been empirically tested. The current study evaluated the effects of punishment and reward on the behavioral and emotional responding of children with and without ADHD. Fifty-three children with ADHD (64.15% boys) and 46 ...

BACKGROUND: Behavioural parent training is an evidence-based intervention for children with attention-deficit/hyperactivity disorder (ADHD), but little is known about the extent to which initial benefits are maintained. AIMS: This meta-analytic review investigated longer-term (i.e., more than 2 months post-intervention) child and parental outcomes of behavioural parent training for children with ADHD. MATERIALS & METHODS: We searched ...

Behavioral parent training (BPT) is an evidence-based treatment for children with attention-deficit/hyperactivity disorder (ADHD). Stimulus control techniques (antecedent-based techniques, e.g., clear rules, instructions) and contingency management techniques (consequent-based techniques, e.g., praise, ignore) are the most common ones that are being taught to parents in BPT. However, research into the additive effects of these techniques is ...

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 ...
