Objective: Adverse childhood experiences (ACEs) are early life experiences that influence mental health outcomes, though there are mixed findings reported in relation to attention deficit hyperactivity disorder (ADHD) symptoms. The current study compared adults who experienced ACEs on measures of ADHD symptom reporting, psychological symptoms, and…

Academic acceleration, which enhances challenges for academically gifted students, can be subject-based or whole-grade. Limited research has explored its application in the twice-exceptional population, where students possess notable cognitive strengths and challenges due to psychological diagnoses. Our clinical study investigates the likelihood…

Background and purpose: The purpose of this study was to assess the level of mental disorders and challenging behaviour in individuals with intellectual disability (ID) supported by specialized services, but without a prior psychiatric diagnosis, and to compare the levels of different disorders depending on the severity of ID. Methods: This is a…

Autistic adults are at risk of stress-related psychiatric disorders and reduced life quality due to social, cognitive, and perceptual challenges. Mental health interventions adapted to autistic adults are scarce. Acceptance and commitment therapy has preliminarily indicated health benefits in autistic adults, although it has not been robustly…

Data on psychiatric problems in adults with autism are inconsistent, with estimated rates ranging from around 25% to over 75%. We assessed difficulties related to mental health in 58 adults with autism (10 females, 48 males; mean age 44?years) whom we have followed over four decades. All were of average non-verbal intelligence quotient when…

College students with attention-deficit/hyperactivity disorder (ADHD) are at greater risk than peers for impaired educational functioning; however, little is known regarding their longitudinal academic outcomes. This study examined: (a) differences between ADHD and control participants in academic outcomes (i.e., semester GPA, credits attempted,…

This study reports on the pattern of performance on spoken and written naming, spelling to dictation, and oral reading of single verbs and nouns in a bilingual speaker with aphasia in two first languages that differ in morphological complexity, orthographic transparency, and script: Greek (L1a) and English (L1b). The results reveal no verb/noun…

Youth with autism spectrum disorder (ASD) often present with emotional problems such as anxiety and depression (American Psychiatric Association, 2013). A recent study of the "Child Behavior Checklist 6-18" (CBCL; Achenbach & Rescorla, 2001) indicated good sensitivity but relatively low specificity for identifying emotional problems…

A psychometric evaluation on the measurement of self-report anxiety and depression using the Beck Depression Inventory (BDI-II), State Trait Anxiety Inventory, Form-Y (STAI-Y), and the Personality Assessment Inventory (PAI) was performed using a sample of 534 generally young adults seeking psychoeducational evaluation at a university-based clinic.…

In children with autism spectrum disorders, previous studies have shown high rates of psychiatric comorbidity. To date, studies on adults have been scarce. The aim of the present study was to investigate psychiatric comorbidity in young adults with Asperger syndrome. Participants were 26 men and 28 women (mean age 27 years) with a clinical…

A well-documented finding in developmental psychopathology research is that different informants often provide discrepant ratings of a youth's internalizing and externalizing problems. The current study examines youth- and parent-based moderators (i.e., youth age, gender, and IQ; type of psychopathology; offense category; psychopathic traits;…

Background: This study investigates the role of IQ, autistic traits and challenging behaviours in affecting adult outcomes among adolescents who receive special educational assistance. Methods: A total of 58 participants were recruited from an ongoing longitudinal study. All received assessments of IQ, behavioural patterns (using the Childhood…

The General Ability Index (GAI) was compared with Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) Full Scale Intelligence Quotient (FSIQ) from the WAIS-III in data obtained from 381 adults assessed for reported learning or attention problems between 1998 and 2005. Not only did clients with more neurocognitively based disorders (i.e.,…

Objective: The main aim of this study was to examine the age-dependent remission from ADHD in girls transitioning through childhood into adolescence and early adulthood. Method: We conducted a 5-year prospective follow-up study of 123 girls with ADHD and 106 non-ADHD control girls aged between 6 and 17 years at ascertainment. ADHD was considered…
