Valid data are essential for making correct theoretical and practical implications. Hence, efficient methods for detecting and excluding data with dubious validity are highly valuable in any field of science. This paper introduces the idea of applying autocorrelation analysis on self-report questionnaires with single-choice numbered, preferably…

Background: We explored the accuracy of using the learning disability screening questionnaire (LDSQ) in services for people experiencing homelessness in the United Kingdom. Method: We examined the concordance between the LDSQ outcomes and assessments of intellectual disability. Seventy adults experiencing homelessness completed the LDSQ. Staff…

We conducted a psychometric synthesis of the internal consistency reliability and internal structure of scores on the English versions of the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) in publications between 2012 and 2022. Results supported acceptable-to-strong reliability and validity evidence of scores…

Direct observation of classroom behavior in young children enriches our understanding of their behavior in its natural context, informing both assessment and intervention strategies to foster supportive learning environments. However, a notable gap in the literature concerning effective direct observation tools specifically designed for this…

Psychosocial competencies; such as prosocial behaviors, compliance with authority, attention regulation, independence, and emotional regulation; play a crucial role in child development. Higher levels of these competencies in childhood are linked to fewer behavior problems, while deficits in these competencies can predict future problem behaviors.…

Identifying children with developmental disabilities is critical in providing early intervention services. This study aimed to evaluate the concurrent validity information of the 24-, 30-, and 36-month Indonesian Ages and Stages Questionnaires third edition (ASQ-3) with Bayley Scales of Infant and Toddler Development 3rd Edition (BSID-III) in…

The Strengths and Difficulties Questionnaire (SDQ) is a brief instrument developed primarily for screening children and adolescents for social-emotional learning. The SDQ contains four factors related to socio-emotional difficulties and one factor related to prosocial behaviour. However, studies of its factor structure have produced mixed results.…

The transition to university is an exciting yet challenging period for many students. While previous research has documented the association between stress and adjustment, little is known about the long-term effect of students' early stress on their subsequent university adjustment. The present study sought to examine the effectiveness of a short,…

Duplication of chromosome 15q11.2-q13.1 (dup15q syndrome) results in hypotonia, intellectual disability (ID), and autism symptomatology. Clinical electroencephalography has shown abnormal sleep physiology, but no studies have characterized sleep behaviors. The present study used the Children's Sleep Habits Questionnaire (CSHQ) in 42 people with…

This study examined the agreement between the Ages & Stages Questionnaires, third edition (ASQ-3), and the Ages & Stages Questionnaires: Social-Emotional, second edition (ASQ:SE-2), and investigated the relationship of the overall indication of "parental concerns" about their child's behavior on the ASQ-3 and the results of the…

Mental health conditions are more prevalent in autistic people than non-autistic people. The Strengths and Difficulties Questionnaire is a commonly used screening tool for emotional and behavioural difficulties in autistic children and adolescents. However, few studies have assessed the psychometric properties of the Strengths and Difficulties…

This study examined the content validity and preliminary structural validity of the Sensory Integration Infant Routines Questionnaire (SIIRQ), a tool designed to screen for behaviors reflecting possible sensory integration concerns in children aged between 8 and 24 months. This study included two main phases. In phase 1, we examined content…

Behavioral and emotional disorders in childhood can have lasting impacts in areas such as education and future employment, often extending into adulthood. Identifying the potential disorders in children's early grades is beneficial to provide proactive assistance. In this study, we employed a well-validated scale - the Strengths and Difficulties…

The current study explored similarities and differences in parenting stress (PSI) and behaviours in parent reports of autism spectrum disorder (ASD) and attachment disorder (AD). 155 parents whose children had developmental delays and disorders completed the social communication questionnaire, Randolph attachment questionnaire, strengths and…

Many children with developmental delays need early intervention services but do not receive them. Developmental screening provides the impetus for identification of delays and service referrals but is not used consistently across all early childhood education settings. We used an implementation science framework to examine attitudes and engagement…
