This intervention case study is written by an Educational and Child Psychologist in the Republic of Ireland, which took place with Leah, a 15-year-old adolescent with a diagnosis of autism attending a post-primary school. Pre- and post-intervention assessment measures included the Strengths and Difficulties Questionnaire (SDQ) and the Rosenberg…

Background: In addition to symptoms of neurodevelopmental disorders, functional impairment is crucial to the determination of clinical significance. The aim of this study was to examine partial validity and usefulness of the Strengths and Difficulties Questionnaire's (SDQ) impact supplement (SDQ impact) in measuring functional impairment in…

Before adopting a scale for a new culture, researchers should conduct systematic translation procedures and evaluations to ensure its psychometric quality. The Pediatric Symptom Checklist-17 (PSC-17) is a brief and valid scale developed by U.S. researchers to evaluate children's emotional, attentional, and behavioral problems. This study aimed to…

The Boxall Profile is one of the most frequently used tools to measure the social, emotional, behavioural and/or mental health difficulties (SEMH) of children and young people in schools across the UK. However, limited evidence exists regarding the norms and psychometric properties of the tool. The current study used data from 487 primary…

This brief report presents an analog test of the relative classification validity of three cutoff values (CVs; 16, 18, and 20) derived from responses to the self-report version of the Strengths and Difficulties Questionnaire: Total Difficulties Scale. Results from Bayesian t-tests, using several school-specific subjective well-being indicators as…

Substantial evidence endorses the early assessment of cognitive development to promote children's developmental health and well-being. Especially in the Brazilian context, there is a paucity of standardized screening and assessment tools with normative data to evaluate young children. This study provided initial reliability and validity evidence…

This study investigated both the risk factors and the protective factors against peer rejection at multiple levels in children with attention-deficit/hyperactivity disorder (ADHD) and their typically developing peers. Using standard sociometric procedure, we studied the peer rejection of 108 children with ADHD (aged 7 to 12) and their classmates…

The mediators of real-world executive functions in autism during the transition into adulthood are mainly unknown. This study aimed to identify the mediators for the behavioral and cognitive domains of real-world executive functions in late adolescent and young adult autistic populations. We followed up 289 autistic children (aged 11.6 ± 3.8, male…

The Strengths and Difficulties Questionnaire (SDQ), with its three forms (youth, parent and teacher version), is widely used to assess emotional and behavioural disorders in children and adolescents. The present study examined the factor structure and psychometric properties of the teacher version of the scale (SDQ-T) with adolescents from…

We examined representations of attachment security using story stem narratives (Manchester Attachment Story Task, MCAST) and a family drawing task in 50 Greek children between 4 and 6 years old. Additionally, we examined the association between attachment classification based on the family drawing task and maternal reports of social and emotional…

The purpose of this study was to explore the roles, perspectives, and actions of teachers and students for first-time-detained juvenile delinquents by examining a reading intervention for a student. Using an action research methodology, the reading intervention was explored within the broader context of the history and operations of the juvenile…

The purpose of the present study was to investigate the preliminary structural, convergent, and incremental classification validity of responses to the Subjective Academic Problems Scale (SAPS), which is a seven-item self-report behavior rating scale intended for use as a triaging tool within secondary-level school mental health screening…

Background: Intellectual disability (ID) is associated with polypharmacy particularly off-label psychotropics for "challenging behaviour." NHS England introduced the "stopping over medication of people with a learning disability (LD), autism or both" (STOMP) initiative. As ID services are a professionally diverse group, it is…

Adults with autism and subclinical autistic traits report greater internalizing problems than their peers, but the psychological processes underlying these associations are not well understood. The current study used structural equation modeling to examine whether social experiences (social connectedness and loneliness) mediate the link between…

This paper assesses the reliability and validity of the teacher-completed Pupil Behaviour Questionnaire (PBQ), by comparing it to the already extensively validated teacher-completed Strengths and Difficulties Questionnaire (SDQ). Participants included 2074 primary school children participating in a universal school-based trial and 41 vulnerable…
