Reliable measures are required to draw meaningful conclusions regarding developmental changes in longitudinal studies. Little is known, however, about the test-retest reliability of face-sensitive event related potentials (ERPs), a frequently used neural measure in infants. The aim of the current study is to investigate the test-retest reliability of ERPs typically evoked by faces in 9-10 month...

This project examined some of the common constraints on reliable cognitive assessment for children over time. Repeated measures design (n = 133) was with younger (5 & 6 year old, n = 64) and older (7 & 8 year old, n = 69) children. Results showed that children’s self-concepts moderated the test-retest reliability over extended intervals for younger and older children. Social self-categorization...

The purpose of this study was to determine the level of interobserver and test-retest reliability of the Milani-Comparetti Motor Development Screening Test. Sixty healthy children, aged 1 through 16 months, were videotaped during administration of the Milani-Comparetti test. Four pediatric physical therapists independently viewed each videotape and scored the responses. Interobserver reliabilit...

This study aimed to investigate the test-retest reliability of a Mandarin Chinese version of the Childhood Autism Spectrum Test (CAST), in a Chinese population. Parents in a school based study on the prevalence of ASC in mainland China were asked to complete a second version of the CAST approximately 2-4 months after first completion. Test retest data were available from 70 children (questionna...

The components of life must survive in a cell long enough to perform their function in that cell. Because the rate of attack by water increases with temperature, we can, in principle, predict a maximum temperature above which an active terrestrial metabolism cannot function by analysis of the decomposition rates of the components of life, and comparison of those rates with the metabolites' mini...

The Youth Sport Environment Questionnaire (YSEQ) had been developed from Group Environment Questionnaire, a well-known measure of team cohesion. The aim of this study was to adapt and examine the reliability and validity of the Farsi version of the YSEQ. This version was completed by 455 athletes aged 13-17 years. Results of confirmatory factor analysis indicated that two-factor solution showed...

This study used a theoretically-derived set of items of the Achenbach System of Empirically Based Assessment to develop the Achenbach Self-Control Scale (ASCS) for 7-16 year olds. Using a large dataset of over 20,000 children, who are enrolled in the Netherlands Twin Register, we demonstrated the psychometric properties of the ASCS for parent-, self- and teacher-report by examining internal and...
