A sequential design utilizing identical samples was used to classify mixed methods studies via a two-dimensional model, wherein sampling designs were grouped according to the time orientation of each study's components and the relationship of the qualitative and quantitative samples. A quantitative analysis of 121 studies representing nine fields…

Concurrent validity testing of the Slosson Intelligence Test-Revised with the Stanford-Binet Intelligence Scale (Fourth Edition), involving 191 individuals (ages 5-69 and IQs of 36 to 110), found a high correlation between the two scales. However, the Slosson unsatisfactorily matched the Stanford-Binet's assignment of individuals to IQ categories.…

Data on 52 individuals with and 62 individuals without autism were analyzed to assess developmental aspects of the DSM-III-R (Diagnostic and Statistical Manual III, Revised) diagnostic system. Findings indicate that DSM-III-R criteria are more developmentally oriented and more behaviorally specific than previous criteria, but the diagnostic…

Examined the validity of eight socioeconomic status measures as reported by adolescents and compared to information from their mothers. Found relatively high agreement between adolescents and mothers, supporting criterion validity. Found that most adolescent-reported measures varied systematically and in the expected direction with mothers' income…

Quality measures were originally developed for research aimed at describing the settings that children spend time in and identifying the characteristics of these environments that contribute to children's development. They were also developed to guide improvements in practice. Increasingly, however, measures of quality are being used for further…

CSCL research has given rise to a plethora of analysis methods, all with specific analysis goals, units of analysis, and for specific types of data (chat, threaded discussions, etc.). This article describes some challenges of CSCL-analysis. The development of an analysis method for negotiation processes in multidisciplinary teams serves as an…

Background/Context: For over two decades, the boundaries between the social sciences and the humanities have become blurred, and numerous articles and books have been written about the infusion of the arts in qualitative research as a means to collect and analyze data and to represent findings. Yet these arts-based research processes, although…

Psychometric evaluation of the Preschool and Kindergarten Behavior Scales (PKBS) is reported. Factor analyses indicated the presence of a stable factor structure for both social skills and problem behaviors scales. Reliability studies indicated the PKBS has adequate-to-strong stability. Explorations of within-scale relationships yielded evidence…

The concurrent validity of three types of reading ability assessments was evaluated with 312 Australian primary-level children. Results suggest that the nature of the skills required for success in reading changes in the primary years, and that both teacher-based and test-based assessments concur more closely as children progress through the…

This paper focuses on issues of data trustworthiness in praxis-oriented empirical work, research openly committed to the building of a world in which we can all flourish. The central argument is that those exploring the possibilities for a change-enhancing advocacy paradigm for doing empirical research in the human sciences must begin to be more…

The Nuclear Locus of Control (NLOC) scales were constructed to assess beliefs as to whether nuclear war and nuclear policy decisions are, or can be, influenced by oneself, powerful others, or chance. Three scales measuring internal, powerful others, and chance nuclear LOC show internal consistency estimates (Cronbach's Alpha) of .87, .76, and .85,…

The concurrent validity of the Battelle Developmental Inventory was explored by correlating Battelle results with scores from the Bayley Scales in 30 infants with known or suspected disabilities. Both the pattern and strength of the obtained correlations support use of the Battelle to measure development in infants with handicaps. (Author/JDD)

This study, involving 118 adolescents and adults with deafness, found a high level of concurrent criterion validity for the National Independent Living Skills (NILS) Screening Instrument. The study concluded that the NILS is a valid tool for assessing independent living skills of persons age 16 and older with a hearing impairment and possible…

A total of 413 students in grades 1-6 were administered the Basic Academic Skills Samples, the Gates-MacGinitie Reading Tests, and the Metropolitan Achievement Test. Although the relationships among the three tests were reasonably strong, it appeared that the measures did not identify identical populations of at-risk students. (Author/JDD)

Because the main criterion of structural homology (the principle of connections) does not exist for behavioral homology, the utility of the ethological concept of homology has been questioned. The confidence with which behavioral homologies can be claimed varies inversely with taxonomic distance. Thus, conjectures about long-range phylogenetic…
