Background: Accurate measurement of adaptive behaviour is important in both clinical and research contexts. While several good clinical measures exist, as well as brief research measures for adults with intellectual disability, there is need for a brief and efficient measure for research with children and youth. We present preliminary psychometric…

Background: The Manchester Attachment Scale-Third party observational measure (MAST) was developed to assess secure attachment style for adults with intellectual disabilities. The psychometric properties of the MAST were examined. Materials and Methods: Professional carers (N = 40) completed the MAST and measures related to the construct of…

Recent insight into the underlying molecular and cellular mechanisms of fragile X syndrome (FXS) has led to the proposal and development of new pharmaceutical treatment strategies, and the initiation of clinical trials aimed at correcting core symptoms of the developmental disorder. Consequently, there is an urgent and critical need for outcome…

The psychometric properties of the Pediatric Anxiety Rating Scale (PARS), a clinician-administered measure for assessing severity of anxiety symptoms, were examined in 72 children and adolescents diagnosed with an autism spectrum disorder (ASD). The internal consistency of the PARS was 0.59, suggesting that the items were related but not…

With the recent increase in the use of functional behavior assessment (FBA) in school settings, there has been an emphasis in practice on the development and use of effective, efficient methods of conducting FBAs, particularly indirect assessment tools such as interviews. There are both benefits and drawbacks to these tools, and their technical…

Early identification of social-emotional behavioral problems in infants and preschoolers is critical. Nine parent-report and caregiver/teacher-report instruments measuring preschool social-emotional behavioral problems and strengths are reviewed. Advantages to the use of parent-report and caregiver/teacher-report instruments are that they are easy…

Four staff members completed 3 questionnaires evaluating quantitative and qualitative aspects of compulsive and autistic behaviors of 17 young autistic adults in a farmstead residential facility. Results affirmed the utility and applicability of obsessive-compulsive assessment devices in evaluating behavior of autistic adults. (Author/DB)

This study examined the validity and reliability of the Pre-school Behaviour Checklist (PBCL) for Turkish nursery school children. Data were obtained from 902 children, 24 to 82 months old, attending state or private nursery schools. Findings suggested that the PBCL has psychometric properties comparable to the British sample and could be used…

In studies of classroom behavior modification, the experimenter or educator attempts to make valid judgments about desirable behavioral outcomes. Instruments of assessment to be used with behavior modification treatments must be sensitive to the behavioral goals of principals, teachers, and public school officials. Moreover the treatments used in…

Standardized rating scales are the most often used part of the multidimensional assessment of children's behavior. However, low cross-informant correlations raise concerns about the reliability and validity of the resulting scores. This study examined whether the manner in which behavioral constructs are measured differs across informants, across…
