Threshold analysis has recently been proposed to be used in combination with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) in order to assess the sensitivity to plausible bias of treatment recommendations derived from Bayesian network meta-analysis (NMA). Here, it was aimed to apply the combination of threshold…

In baseball, it is believed that "hitting is contagious," that is, probability of success increases if the previous few batters get a hit. Could this effect be partially explained by action induction--that is, the tendency to perform an action related to one that has just been observed? A simulation was used to investigate the effect of inducing…

Phosphatase and tensin homolog-induced putative kinase 1 gene mutations have been associated with autosomal recessive early-onset Parkinson's disease. To date, no neuropathological reports have been published from patients with Parkinson's disease with both phosphatase and tensin homolog-induced putative kinase 1 gene copies mutated. We analysed…

Recent research has suggested that young children have relatively well-developed trait concepts. However, this literature overlooks potential age-related differences in children's appreciation of the fundamentally dimensional nature of traits. In Study 1, we presented 4-, 5-, and 7-year-old children and adults with sets of characters and asked…

Objectives: This article presents a systematic review of the evidence on problem-solving therapy (PST) for depressive disorders in noninstitutionalized adults. Method: Intervention studies using randomized controlled designs are included and methodological quality is assessed using a standard set of criteria from the Cochrane Collaborative Review…

The authors review the contribution of qualitative methods to exploring concepts and experiences of wellbeing among children and adults living in developing countries. They provide examples illustrating the potential of these methods for gaining a holistic and contextual understanding of people's perceptions and experiences. Some of these come…

This fact sheet provides answers to frequently asked questions about psychological evaluations for infants, children and adults who are deaf-blind, we hope to clarify the evaluation process and the active roles that may be taken by everyone who is involved--family members, professionals, educators, and the student. Finally, by discussing quality…

Research in training, development and education (TD&E) in organizations has produced important results in the last two decades. Evaluation of TD&E has been a special focus of this research, which has resulted in the production of relevant predictive models. The present study has the aim of testing a model of effectiveness of training on…

The GED (General Educational Development) Tests are widely used to certify a high school level of academic knowledge and skills. The popularity and profound influence of the GED Tests have solicited numerous studies on the outcomes of obtaining a GED credential. Most studies on labor market outcomes for GED credential recipients have targeted…

This article provides an introduction to the use of event-related potential (ERP) approaches to study language processes. First, a brief history of the emergence of this technology is presented, followed by definitions, a theoretical overview, and a practical guide to conducting ERP studies. Examples of language studies that use this technique are…

The validity of a technique for estimating premorbid intellectual functioning based on Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtest performance and demographic information used in best-performance fashion was investigated with the 1,880 individuals from the WAIS-R standardization sample. Results support use of the approach. (SLD)

Although the National Institutes of Health Consensus Development Conference on the Treatment of Panic Disorder endorsed the effectiveness of cognitive-behavior therapy (CBT), D. F. Klein argues that fatal flaws in all but one CBT study undermine claims about the effectiveness of CBT for panic disorder. This article critiques Klein's arguments and…

The paper describes a data collection system useful for monitoring the progress of severely and profoundly retarded clients. Three studies are reviewed which utilized data based systems: a staff injury prevention program with eight employees, a program which taught instruction following skills to 59 severely and profoundly retarded adults, and a…

In this response to critiques (Mudford, Hogg and Roberts 1997, 1999) of the use of behavior states in research involving individuals with mental retardation, it is argued that the work on behavioral state analysis by Robert D. Guess has contributed to the field at the practical, empirical, and theoretical levels. (Contains references.) (CR)

This article contrasts the traditional relationships between researchers and subjects in traditional rehabilitation evaluation and research with relationships between researchers and clients-consumers in new methodologies. Collaborative research, characterized by shared power and non-hierarchical authority between client-consumers and researchers…
