Advocacy has long been heralded as a way to create change for individuals with intellectual and developmental disabilities (IDD) and their families. However, without an established measure, it is difficult to accurately characterize advocacy activities. Drawing from extant research, the Advocacy Activities Scale was developed to assess three…

Effective support for children with developmental disabilities or delays is dependent on the successful collaboration between families and professionals and among professionals. For years, researchers and professionals have been coaching caregivers and other professionals to implement evidence-based practices with children with disabilities.…

Teachers are often mentioned among the key factors in the quality of the teaching process. This research aims to adapt to Serbian the Teacher Efficacy for Inclusive Practice (TEIP) Scale, and identify factors that correlate with high levels of perceived efficacy.

Parent readiness is an important aspect of having young adults embrace their increasing independence. While the prospective…

Peer-mediated interventions (PMIs) offer substantial benefits to middle school, high school, and post-secondary students with intellectual and developmental disabilities (IDD). However, with no valid and reliable measure to capture the ways in which the peers without disabilities are impacted, far less is known about the outcomes for these…

Background: Sensory irregularities are commonly seen across developmental and intellectual disability groups. Identifying patterns of dysfunction within these clinical groups facilitates the development of appropriate intervention strategies. Thus, we evaluated the psychometric properties of the new Sensory Processing (SP) Scale Inventory rating…

Background: Assessment of psychiatric disorders in persons with an intellectual developmental disorder (IDD) can be performed with a variety of greatly differing instruments. This makes the choice of an instrument best suited for the intended purpose challenging. In this study, we developed a comprehensive set of characteristics for the evaluation…

The Delis Rating of Executive Function (D-REF) is a set of rating scales designed to assess executive functions and their constituent sub-processes in children and adolescents between the ages of 5 and 18. More specifically, the D-REF is a supplemental assessment of children and adolescents demonstrating behavioral or cognitive difficulties often…

The present study reports on the design and an initial empirical evaluation of the Well-being in Special Education Questionnaire (WellSEQ). Questions, response scales,…

Research Findings: Parents' meta-emotion philosophy guides their approach to teaching their children about emotions (J. M. Gottman, L. F. Katz, & C. Hooven, 1997) and is measured with the Emotion-Related Parenting Styles Self-Test-Likert (Gottman et al., 1997, modified by J. Hakim-Larson, A. Parker, C. Lee, J. Goodwin, & S. Voelker, 2006).…

Purpose: Accurate description of an individual's communication status is critical in both research and practice. Describing the communication status of individuals with severe intellectual and developmental disabilities is difficult because these individuals often communicate with presymbolic means that may not be readily recognized. Our goal was…

The purpose of this study was to develop and to evaluate the Preferences for Leisure Attributes (PLA) Assessment, a forced-choice computer software program for students with severe disabilities and communication difficulties. In order to determine content validity of the PLA Assessment, four experts in related fields assigned critical attributes…

Background: Individuals with Angelman syndrome (AS) seem to have a strong preference for water-related items. Until present, preference assessment in AS has not been reported. Methods: An adapted Dutch version of the Choice Assessment Scale (CAS) was administered by parents and other caregivers to 105 individuals with AS. The CAS was adapted by…

The use of anti-epileptic medications (AEDs) is much higher in individuals with intellectual disabilities than in the general population. As many of these individuals rely on such medications, clinicians should consider psychometrically sound instruments for assessing adverse side effects of these medications as one aspect of routine clinical…

Steps are outlined in the construction of two self-report assessment scales designed to measure general life satisfaction and leisure activity levels of developmentally disabled adults. The potential usefulness of a reliable, valid self-report instrument as a measurement tool in client programming is noted in the context of a review of similar…
