Several studies have shown that the symptoms of grief are different from symptoms of depression among bereaved family members. This study is an attempt to replicate this finding among advanced cancer patients and examine clinical correlates of patient grief and depression. Analyses were conducted on data from interviews with 123 advanced cancer…

Background: Executive functioning (EF) is an important concept in cognitive psychology that has rarely been studied in people with intellectual disabilities (IDs). The aim of this study was to examine the validity of two test batteries and the structure of EF in this client group. Methods: We administered the children's version of the Behavioural…

In 2 studies, the psychometric properties of 3 methods for measuring real-ideal and real ought self-discrepancies were compared: the idiographic Self-Concept Questionnaire--Personal Constructs, the nonidiographic Self-Concept Questionnaire--Conventional Constructs, and the content-free Abstract Measures. In the 1st study, 125 students at a…

The Tower of London (TOL) is a widely used instrument for assessing planning ability. Inhibition and (spatial) working memory are assumed to contribute to performance on the TOL, but findings about the relationship between these cognitive processes are often inconsistent. Moreover, the influence of specific properties of TOL problems on cognitive…

This study adapted the Mathematics Anxiety Rating Scale-Short Version (MARS-SV) into Turkish and investigated the validity and reliability of the adapted instrument. Twenty-five bilingual experts agreed on the language validity, and 49 Turkish language experts agreed on the conformity and understandability of the scale's items. Thirty-two subject…

The GARS-2 (Gilliam 2006) is widely used for autism screening; however, the validity of its three conceptually-derived subscales has not been evaluated. In this study, exploratory (EFA) and confirmatory (CFA) factor analyses of data from matched subgroups of the standardization sample did not support the GARS-2 subscale structure. EFAs identified…

The present study tested the dual-component model of working memory capacity (WMC) by examining estimates of primary memory and secondary memory from an immediate free recall task. Participants completed multiple measures of WMC and general intellectual ability as well as multiple trials of an immediate free recall task. It was demonstrated that…

The present article describes and evaluates the Youth Counseling Impact Scale (YCIS; L. Bickman et al., 2007), a recently developed therapeutic process measure that assesses youths' perceptions of the impact individual mental health counseling sessions have on their thoughts, feelings, and behaviors. This measure is intended for frequent use in…

The measurement of dental fear is important due to its high prevalence and appreciable individual, clinical, and public health consequences.

This paper compares different theoretical models of the structure of intelligence, based on the analysis of data obtained in a series of measured abilities corresponding to the Spectrum assessment activities (Gardner, Feldman & Krechevsky, 1998) in a sample of 393 children enrolled in kindergarten and first grade. The data were analyzed using…

The purpose of this study was to develop an attitude and a self-efficacy survey of using PDAs in ubiquitous learning (u-learning) environments for elementary school students. The sample of this study included 414 third-grade to sixth-grade students (age 9-12 years) in Taiwan who had experience using PDAs for u-learning. The results indicate that…

Item factor analysis has a rich tradition in both the structural equation modeling and item response theory frameworks. The goal of this paper is to demonstrate a novel combination of various Markov chain Monte Carlo (MCMC) estimation routines to estimate parameters of a wide variety of confirmatory item factor analysis models. Further, I show…
