The broad autism phenotype is the phenotypic expression of the primary characteristics of autism. However, currently available tests do not agree with the two-domain operationalization of broad autism phenotype or autism, and their internal structure has shown instability across applications. This study presents the Broad Autism…

Despite several psychometric advantages over the 50-item Autism Spectrum Quotient, an instrument used to measure autistic traits, the abridged AQ-28 and its cross-cultural validity have not been examined as extensively. Therefore, this study aimed to examine the factor structure and measurement invariance of the AQ-28 in 818 Dutch (M[subscript…

The National Association of School Psychologists' Model for Comprehensive and Integrated School Psychological Services (2010a), often referred to as the National Association of School Psychologists' Practice Model, describes the comprehensive range of professional skills and competencies available from school psychologists across 10 domains. The…

Presents psychometric investigation of the eight-factor clinical model of the Suicide Opinion Questionnaire (SOQ) as representing the most appropriate interpretive model for the SOQ. Notes that factor-analytic and internal consistency reliability results failed to support hypothesized eight-factor model. Discusses alternative factor scheme and…

The Ohio Vocational Interest Survey (OVIS) has been used as an interest measurement tool measuring student interests toward jobs dealing with data, people and things. The purpose for the present paper was to determine the consistency of the OVIS for measuring these three dimensions through factor analysis. The research findings demonstrated which…

This study was designed to factor analyze the correlation matrices of a number of studies utilizing the Illinois Test of Psycholinguistic Abilities (ITPA). All of the correlation matrices were analyzed on the same program using the same criteria. By this approach, it was possible to examine trends between studies. More factors tended to appear as…

Results of factor and correlational analyses of the Ethical Behavior Rating Scale (EBRS) are reported. The test-retest method and internal consistency estimates yielded reliability coefficients. Construct validity was determined by correlating the EBRS with items from the Ethical Reasoning Inventory. The EBRS reflects the behavioral aspects of…

The purpose of the Florida KEY is to provide teachers with a single instrument to infer self-concept as learner of students in grades 1-6. The KEY identifies selected behaviors of students who seem to possess positive and realistic self-concepts in the area of school success. The KEY contains 23 interrogative items that describe student behavior…

A general working model of cognitive development assumes that there are sets of orthogonal cognitive abilities, which remain fairly stable after age 7. This paper examines the long term predictive and diagnostic value of assessing specific cognitive abilities among preschool children. This model by empirical studies was defendable on the grounds…

Three tables are provided to aid in the clinical interpretation of factor scores for the Wechsler Adult Intelligence Scale-Revised (WAIS-R; 1981). The factor structure of the WAIS-R has proven to be robust across samples, tests, time, statistical analyses, measurement scales, and distortions of the distribution. Information necessary to make…

The Addiction Research Center Inventory is a 550 item multipurpose test measuring the broad range of physical, emotive, cognitive, and subjective effects of drugs. This manual provides technical information concerning 38 most valid scales, a quantitative method for characterizing the similarity of a profile of scores for the subject, group, or…

This is a progress report on research conducted (1) to consider the methodological issues of response set and multidimensionality, which might lead to a refinement of the Test Anxiety Scale for Children (TASC) and the Defensiveness Scale for Children and (2) to investigate social background and school achievement correlates of test anxiety and…

The development of the Parent Attitudes toward School Effectiveness (PATSE) questionnaire was conducted in two phases. The pilot test form contained 47 items reflecting parents' attitudes toward 6 categories: (1) school and community relationships; (2) clear school mission; (3) high expectations; (4) safe and orderly environment; (5) instructional…

This examiner's manual accompanies the Learning Style Profile (LSP), which measures cognitive skills as well as affective and environmental preferences. Charles Letteri's General Operations Model was accepted as the prototype for relating learning styles to cognitive information processing. The LSP was developed from 1983 to 1986; several versions…
