Psychiatric disorders in individuals with co-occurring autism spectrum disorders (ASD) and intellectual disability (ID) are common, but diagnosis presents many challenges. The Psychopathology in Autism checklist (PAC) is among the very few instruments specifically developed for this group of individuals. The psychometric properties of the PAC…

Background: Shame has been found to relate to several psychopathologies, but the way the individual copes with experiences of shame may determine specific expressions of psychopathology, making it essential to rigorously address such coping styles. Objective: This study evaluated the psychometric properties of a Portuguese version of the Compass…

R. Goodman's Strength and Difficulties Questionnaire (SDQ) is widely used to measure emotional and behavioral difficulties in childhood and adolescence. In the present study, we examined whether the SDQ measures the same construct across time, when used for longitudinal research. A nationally representative sample of parents (N = 3,375) provided…

Background: While child self-reports of psychopathology are increasingly accepted, little standardized instruments are utilized for these practices. The Berkeley Puppet Interview (BPI) is an age-appropriate instrument for self-reports of problem behavior by young children. Objective: Psychometric properties of the Dutch version of the BPI will be…

The benefits of early intervention for very young children with autism are now well established. Hand and hand with these interventions is the necessity of psychometrically sound diagnostic tools. Not only should these tools be instrumental in differentiating developmentally delayed and other at risk infants. These measures should also be…

The Strengths and Difficulties Questionnaire (SDQ) is an instrument developed by Goodman for screening child and adolescent psychopathology. The aim of this study is to contribute to the analysis and validation of the internal structure of the Italian SDQ teacher version (SDQ-T). The SDQ-T was completed by 301 teachers, evaluating 3,302 children…

Young children's expected social behaviors develop within particular cultural contexts and contribute to their academic experience in large part through their relationships with their teachers. Commonly used measures focus on children's problem behaviors, developed from psychopathology traditions, and rarely situate normative and positive…

Psychometric properties of Romanian translations of the "Behavior Problems Inventory-01" ("BPI-01"; Rojahn, Matson, Lott, Esbensen, & Smalls, 2001) and the "Nisonger Child Behavior Rating Form" ("NCBRF"; Aman, Tasse, Rojahn, & Hammer, 1996) were explored. Respondents completed the instruments for 115…

Psychometric properties of the Dutch version of the Affect and Arousal Scales (AFARS) were inspected in a combined clinical and population sample (N = 1,215). The validity of the tripartite structure and the relations between Negative Affect, Positive Affect, and Physiological Hyperarousal (PH) were investigated for boys and girls, younger (8-11…

We tested the psychometric properties of the Hypomania Checklist (HCL-32) in a sample of nonclinical adolescents, examined the association with current psychopathology, and tested if "hypomanic" adolescents differ from other participants regarding HCL-scores and psychopathology. A total of 294 students completed the HCL-32 and the SDQ, a…

The success of early intervention programs has in large part spurred increasing emphasis on identifying children with autism and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) at the earliest possible ages. National and international professional groups have called for early screening and diagnosis, yet the technology to…

Diagnosing autism and PDD-NOS at very early ages has become a major priority in the field of mental health. More recently, researchers have also come to realize the importance of identifying co-occurring conditions of psychopathology in this population. In the present study, 309 children between 17 and 37 months of age who had been identified as…

This study was designed to establish the initial psychometric properties of the first scale specifically developed for behavior problems of adults with Autism Spectrum Disorders (ASD) and intellectual disability (ID). The Autism Spectrum Disorders-Behavior Problems for Adults (ASD-BPA) consists of 20 items in which raters indicate if each item is…

This paper offers a rationale for and a description of the creation of the Developmentally Delayed Children's Behaviour Checklist, which is completed by caregivers or teachers and uses a taxonometric model to describe the child's (ages 4-20) disturbed emotions and behaviors. Results of clinical validation studies are cited. (Author/JDD)
