Restricted repetitive behaviors (RRBs) are a core feature of autism spectrum disorders (ASD) and further occur in intellectual disability (ID), mental disorders (MD), and in typically developed people (TD). There is a need of a valid and reliable measure to record RRBs as transdiagnostic symptom, which captures RRBs heterogeneity and evaluates…

This article aims to adapt and validate the Risk-Taking and Self-Harm Inventory for Adolescents (RTSHIA) in Portuguese. Results confirm the 2-factor structure originally proposed (risk-taking and self-harm). Both dimensions presented an adequate internal reliability and temporal stability. Convergent validity and sociodemographic differences are…

Replication of the Adjustment Scales for Children and Adolescents (ASCA) core syndrome factor structure with a sample of 124 randomly selected Hispanic/Latino youths is reported. The six ASCA core syndromes produced the identical two-factor solution observed in other samples. Principal-axis exploratory factor analysis using multiple factor…

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…

This study was conducted to assess the psychometric properties of 2 assessment instruments, the "Behavior Problems Inventory-01" ("BPI-01"; Rojahn, Matson, Lott, Esbensen, & Smalls, 2001) and the "Nisonger Child Behavior Rating Form" ("NCBRF"; Aman, Tass, Rojahn, & Hammer, 1996).

Impulsivity is central to several psychopathological states in adolescence. However, there is little consensus concerning the definition of impulsivity and its core dimensions. In response to this lack of consensus, Whiteside and Lynam (2001, "Pers. Individ. Differ." 30, 669-689) have developed the UPPS Impulsive Behavior Scale, which is able to…

Independent examination and replication of the core syndrome factor structure of the Adjustment Scales for Children and Adolescents (ASCA; McDermott, Marston, & Stott, 1993) is reported. A sample of 1,020 children were randomly selected from their classroom and rated on the ASCA by their teacher. The six ASCA core syndromes produced a…

No self-report measure of attachment is well validated for middle-childhood. This study examined the validity and factor structure of the People in My Life (PIML) measure in 320 urban, fifth and sixth graders. Validity analyses consisted of correlational analyses between PIML subscales and the Child Behavior Checklist, Delinquency Rating Scale for…

The Nisonger Child Behavior Rating Form (NCBRF) is a behavior rating scale designed for children and adolescents with mental retardation. The purpose of this study was to explore the psychometric properties of the NCBRF in a sample of 330 children and adolescents with autism spectrum disorders (ASDs). Parent and teacher ratings were independently…
