Previous studies have examined the reliability of scores derived from various Stroop tasks. However, few studies have compared reliability of more recently developed Stroop variants such as emotional Stroop tasks to standard versions of the Stroop. The current study developed four different single-stimulus Stroop tasks and compared test-retest…

In the present study we have investigated the acquisition of the past participle of Italian verbs of the second (including mostly irregular verbs) and third (including mostly regular verbs) conjugations in school age children, and with simulations with an artificial neural network. We aimed to verify the extent to which children are sensitive to…

A performance assessment consisting of 10 separate exercises was scored with a randomized scoring procedure. All responses to each exercise were rated once; in addition, a randomly selected subset of the responses to each exercise received an independent second rating. Each second rating was averaged with the corresponding first rating before the…

This article is the third contribution to a research methods series dedicated to getting good results from survey research. In this series, "good results" is a stenographic term used to define surveys that yield accurate and meaningful information that decision makers can use with confidence when conducting program evaluation and policy assessment…

Emotional availability (EA) is a prominent index of socioemotional adaptation in the parent-child dyad. Is EA affected by context? In this methodological study, 34 mothers and their 2-year-olds were observed in 2 different settings (home vs. laboratory) 1 week apart. Significant cross-context reliability and continuity in EA as measured with the…

This paper describes a new instrument for evaluating the experience of the stuttering disorder from the perspective of individuals who stutter. Based on the World Health Organization's "International Classification of Functioning, Disability, and Health" [World Health Organization (2001). "The International Classification of Functioning,…

There is need for objective and reliable single-case research (SCR) results in the movement toward evidence-based interventions (EBI), for inclusion in meta-analyses, and for funding accountability in clinical contexts. Yet SCR deals with data that often do not conform to parametric data assumptions and that yield results of low reliability. A…

This study reports on the replication of the four-factor structure and the internal consistency of the Learning Behaviors Scale (LBS) with an independent sample of 241 students in Grades 1 through 7. Internal consistency estimates were as high or higher than those obtained with the standardization sample. Substantial replication of the four LBS…

Background: Health status is an important domain of quality of life of people with intellectual disabilities. This paper describes the development of a self-report health status measure for use with people with intellectual disabilities living in staffed community-based accommodation, and reports preliminary reliability data for the schedule.…

The Mini-IPIP, a 20-item short form of the 50-item International Personality Item Pool-Five-Factor Model measure (Goldberg, 1999), was developed and validated across five studies. The Mini-IPIP scales, with four items per Big Five trait, had consistent and acceptable internal consistencies across five studies (= at or well above 0.60), similar…

This paper presents a new measure for assessing quality of life (QOL)--the Multidimensional Quality of Life (MQOL)--and describes its derivation, characteristics, structure and several applications. Reasons for developing the MQOL include the restricted range of assessed domains and the heavy emphasis on health in many standard assessment tools.…

A simple errors-in-variables regression model is given in this article for illustrating the method of marginal maximum likelihood (MML). Given suitable estimates of reliability, error variables, as nuisance variables, can be integrated out of likelihood equations. Given the closed form expression of the resulting marginal likelihood, the effects…

Theory-testing can only inform scientific inquiry when the prediction of test outcome is based upon the current theory (theory-prediction consistency). This investigation explores children's theory-prediction consistency in a computer-mediated task in which multiple opportunities were provided to predict outcomes and review theories. An initial…

The Chinese Value of Learning Scale (CVLS) is a 5-item instrument for assessing the value of learning in Chinese culture. The psychometric properties of CVLS were investigated in a convenient sample of 583 Chinese soon-to-be-aged adults in Hong Kong. CVLS possesses high internal consistency and exhibited satisfactory short-term test-retest…

There are few reliable self-report measures suitable for people with a learning disability in reporting psychological distress. This study examines the modification of the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM), exploring its reliability, using two different presentation styles. One style included a sequencing task then…
