Examines the reliability, validity, and sensitivity of experimental measures developed to assess three areas of early literacy: phonological awareness, vocabulary development, and fluency in letter naming. Results indicate which measures display adequate psychometric properties for kindergartners not yet reading. Experimental measures were less…

A study investigated the validity and reliability of a new instrument for assessing the wellness lifestyles of Upward Bound students. Subjects were 42 students from five high schools using the program. The study examined 14 variables, including total scores, 10 subscales, and three demographic variables (age, race, gender), and concluded that the…

A study investigated the effectiveness of a phenotypic checklist for identifying 110 males with fragile X syndrome and 79 controls, matched for age, level of cognitive development, and social adaptation. Results indicated that those boys who are likely to be diagnosed as having fragile X syndrome can be identified. (Contains references.)…

Assessed long-term predictive validity of the MacArthur Communicative Development Inventories: Words and Sentences (CDI:WS) for children's expressive and receptive vocabulary development. Sixty-one New Zealand children were assessed with a New Zealand version of the CDI, and with the Expressive Vocabulary Test and Peabody Picture Vocabulary…

Addresses the issue of the reliability of grammaticality judgment tests and explores what it is that they measure (i.e., their construct validity). Various methods of examining their reliability demonstrate that the grammaticality judgment tests used in this study had relatively low reliability. (Author/VWL)

Describes short-form versions of the MacArthur Communicative Development Inventories (CDIs) and their development, summarizes newly available normative data and psychometric properties of the instruments, and discusses research and clinical applications. (Author/VWL)

A short version of the Approaches to Studying Inventory administered to 169 college psychology students in early semester revealed that scores for meaning orientation did not predict academic performance in any way, whereas there was a very small negative correlation between reproducing orientation and academic achievement. Internal reliability of…

Tests for equivalence models predicting ethnic minority and nonminority students' intentions to remain enrolled in college. Reports similarities and differences in the models for predicting commitment for ethnic minority and nonminority students. Notes limitations to the inferences that can be drawn from the study due to its methodology. (DSK)

Forty neuropsychologists, neurologists, psychiatrists, and physiatrists identified neurologically relevant items (NRIs) in the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Raters identified four sets of NRIs: one for brain damage in general and three partially overlapping sets for stroke, traumatic brain damage, and whiplash.…

The utility of the Test for Severe Impairment was studied with 60 older persons who had Down Syndrome. Construct validity, test-retest reliability, and interrater reliability were established for the full study group and for subgroups based on degree of mental retardation and dementia status. Some possible applications and limitations of the test…

Created a teaching effectiveness rating instrument for use by students at Rand Afrikaans University. Analyzed the questionnaire's reliability and validity and found it to be a useful instrument for formative teaching assessment. (EV)

Investigates the short-term stability of the Adjustment Scales for Children and Adolescents for 124 randomly selected children in grades kindergarten to grade 12. Significant test-retest stability coefficients were obtained and mean differences across the retest interval did not exceed .8 raw score points. Results were similar to those obtained in…

Two studies are reported demonstrating the reliability, validity, and clinical utility of the Language Development Survey (LDS) as a screening tool for the identification of expressive language delay in toddlers. The LDS test-retest reliability was .97. The LDS also correlated highly with other measures and the LDS identified at-risk group scored…

States that standard scores are the numerical universal language for reporting and comparisons. Discusses what standard scores are, specifically, and why they are used, along with how the conversion assessment of raw scores to standard scores is accomplished. Provides contact information for those who would like to further their knowledge on the…

The extent to which testing practices complied with professional guidelines regarding reliability and validity evidence was studied in research appearing in American Psychological Association journals. Documentation of reliability and validity was reported for 20% of the 2,157 instruments studied in these papers. About half supported one or the…
