Background: Adults with intellectual disabilities should participate in the diagnostics of their mental health. The Glasgow Depression Scale for people with a Learning Disability (GDS-LD) and its Carer Supplement (GDS-CS) were translated into German and tested. Methods: Internal consistency, criterion validity and inter-test reliability were…

Perceptual judgments result from a dynamic process, but little is known about the dynamics of number-line estimation. A recent study proposed a computational model that combined a model of trial-to-trial changes with a model for the internal scaling of discrete numbers. Here, we tested a surprising prediction of the model--a situation in which…

The purpose of this study was to examine the factor structure of vocabulary. We believe that not only is vocabulary multidimensional, but depth of vocabulary knowledge should also be assessed with multiple measures since it too, is composed of multiple aspects. Furthermore, to explore the predictive validity of the different aspects of vocabulary…

Background: Mental capacity assessments currently rely on subjective opinion. Researchers have yet to explore the association between key cognitive functions of rational decision making and mental capacity classifications for people with intellectual disabilities. Method: Sixty-three adults completed the Montreal Cognitive Assessment, which…

Quality of life (QoL) is a key outcome used to monitor service planning and delivery for individuals with Intellectual and Developmental Disabilities (IDD). Unfortunately, many current instruments used to measure QoL have psychometric and content limitations and none are suitable for use with individuals with the lowest levels of functioning and…

The Session Rating Scale 3.0 (SRS 3.0) is an ultra-brief measure of the therapeutic alliance, frequently used to provide feedback to the clinician during the therapeutic process (Prescott et al. [2017]. "Feedback-informed treatment in clinical practice. Reaching for excellence." American Psychological Association (APA).…

The use of test scores as a performance measure in high-stakes educational accountability has become increasingly popular since the enactment of the No Child Left Behind Act of 2001 (NCLB), which imposed sanctions such as the threat of losing federal funds unless a state implemented a school accountability system that measures student progress…

Many Flynn effect (FE) studies compare scores across different editions of Wechsler's IQ tests. When construct changes are introduced by the test developers in the new edition, however, the presumed generational effects are difficult to untangle from changes due to test content. To remove this confound, we use the same edition of Wechsler…

We are delighted to welcome you to the International Psychological Applications Conference and Trends (InPACT) 2017, taking place in Budapest, Hungary, from 29 of April to 1 of May, 2017. Modern psychology offers a large range of scientific fields where it can be applied. The goal of understanding individuals and groups (mental functions and…
