This article provides GP-CORE norms for a South African university sample, which are compared to published data obtained from a United Kingdom university sample. The measure appears to be both reliable and valid for this multilingual and multicultural South African sample. The profiles of the psychological distress reported by white South African…

Examines the issue of validity and values in the scientific method of research, and suggests that researchers must continuously question the premises upon which their research is based. (SB)

A pair of related experiments examined the psychometric properties on the Threat Index (TI), a theoretically based scale for the assessment of threat of death. The high reliability of the TI suggested its functioning as an index of stable conceptual orientation toward death. (Author)

This study investigated the reliability and validity of the Philosophical Belief Inventory (PBI). With the exception of the relationship between idealism and pragmatism and realism and existentialism, the PBI scales appear to be assessing independent facets of belief. (Author)

An introductory textbook on psychological tests and measurements is presented in paper back booklet form.

Ten chapters constitute the text: (1) On Measurement and Existence; (2) A Brief, Imprecise History of Psychological Testing; (3) The Creation…

An attempt is made to indicate why the concept of "true score" naturally leads to the belief that test validity must increase with an increase in test and/or average item reliability, and why this is correct for the classical single-factor model first introduced by Spearman. The statistical model used by Loevinger is introduced to…

This study sought to determine the convergent and discriminant validity of the PIAT when administered to separate samples of Anglo and Mexican-American children. Thirty-one Mexican-American and 31 Anglo-American children were matched on the basis of sex, age, SES, educational placement, and reason referred for psychological assessment. All…

An experimental study examined the possibility that proximity error could bias results from semantic differential questionnaires. Proximity error occurs when, due to the ordering, or polarity, of the differential scales, one answer on the semantic differential results in another answer to a subsequent question being substantially changed from what…

COUNSELORS OFTEN ADMINISTER TESTS OF QUESTIONABLE VALIDITY. IN RELIABILITY STUDIES, EVERY PRECAUTION IS TAKEN TO STABILIZE THE STIMULUS SITUATION. IN ASSESSING VALIDITY, CONCERN CENTERS ON BEHAVIOR UNDER DIFFERENT STIMULUS CONDITIONS. CRONBACH'S THEORETICAL LIMIT FOR A VALIDITY COEFFICIENT OF A TEST IS THE SQUARE ROOT OF THE RELIABILITY…

The study's purpose was to use the Adjective Check List (ACL), a self-administered personality assessment instrument, to determine whether there were response differences between a sample of Adult Basic Education (ABE) students and the general test norms. The ACL was administered to 142 students in ABE high school completion programs in Des…

This paper presents data on a follow-up study of a project in the 1960's: a classroom assessment and intervention program directed at mental health for all the first grade classrooms of Woodlawn, a black poor community on Chicago's south side. Now, ten years later, the mental health of these adolescents as well as the mental health, structure, and…
