The present study aimed to: determine the extent to which the five factor model of personality (FFM) accounts for variability in autism spectrum disorder (ASD) symptomatology in adults, examine differences in average FFM personality traits of adults with and without ASD and identify distinct behavioral phenotypes within ASD. Adults (N = 828;…

Using data from a prospective population based study, the prevalence and psychopathological correlates of sibling bullying in children with and without autism spectrum disorder (ASD) were estimated. There were 475 children with ASD and 13,702 children without ASD aged 11 years. Children with ASD were more likely to be bullied by their siblings…

Reducing fixed term exclusions (FTE) in primary schools is a difficult proposition. This research discusses how a partnership of primary schools developed more inclusive systems to support students previously given FTEs for disciplinary purposes. Longitudinal data from interviews and documentary sources trace the development of an approach amongst…

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…

There is a growing interest in mainland China about schools' roles in supporting students to develop positive mental health.

This article reports a collaborative study, by eastern and western researchers, to translate and administer the Strengths…

Questionnaires that include items eliciting count responses are becoming increasingly common in psychology. This study proposes methodological techniques to overcome some of the challenges associated with analyzing multivariate item response data that exhibit zero inflation, maximum inflation, and heaping at preferred digits. The modeling…

The College Student Subjective Wellbeing Questionnaire (CSSWQ) is a 15-item self-report rating scale for measuring four classes of college-specific wellbeing behavior: academic efficacy, academic satisfaction, school connectedness, and college gratitude. The present study investigated the psychometrics of a revised version of this measure, which…

In the present investigation, we studied the development of 6 physically aggressive behaviors in infancy and toddlerhood, posing 3 questions (a) How do the prevalences of individual physically aggressive behaviors change from 8, 15, and 24 months? (b) Are there groups of children who show distinctive patterns in the way individual physically…

Many early educators cite behavior management as a top professional development need. Evidence-based practices exist to address severe challenging behavior, but promoting implementation of these practices remains a challenge. In this single-case design study, two preschool teachers received coaching focused on implementing three evidence-based…

Caregivers of a child with autism spectrum disorder (ASD) often experience elevated distress. The current study examined potential protective factors against caregiver distress when child externalizing and internalizing behaviors are present: family resources, perceived social support, parenting efficacy, knowledge of ASD, and the agreement…

This study explores the level of congruency between students' ratings of their own emotional and behavioral strengths and difficulties, and their teachers' ratings of these factors, when compared amongst two neighboring countries, Estonia and Finland. Secondly, it investigates the level of agreement between sixth grade students' ratings and their…

We examined cross-cultural differences in (1) sibling power balance and (2) the associations between sibling power balance and internalizing and externalizing problems in three separate cross-cultural studies (early childhood, late childhood, and adolescence). The "early childhood samples" consisted of 123 Turkish and 128 Dutch mothers…
