Results with preschool children were nonsupportive and, in fact, contrary to the general hypothesis that high external locus of control would be positively related to greater behavior adjustment problems, as has been found with some groups of older children and adults. (RL)

A correction procedure for estimating correlation coefficients when faced with the problem of a restricted range in the variables due to an explicit selection procedure was empirically investigated. Results indicated that the assumption of linearity is critical, but that homoscedasticity is less important. (JKS)

There are a variety of formulas for reducing the positive bias which occurs in estimating R squared in multiple regression or correlation equations. Five different formulas are evaluated in a Monte Carlo study, and recommendations are made. (JKS)

The determination of a consensus ranking of products based on the rankings of each judge can be accomplished through the use of a Tukey type multiple comparison procedure. The extension to more than two groups is presented as an analysis of concordance table. (Author/CTM)

To determine the extent of students' confidence-judgment accuracy (CJA) and the relationship of this memory-monitoring ability to overall test performance, undergraduates in a psychology course supplied confidence-judgments along with their answers on multiple-choice test items. CJA correlated positively with test performance. (Editor/SJL)

Investigates the relationship between the annual variations in United States suicide rates during the years 1966 to 1973 and the concomitant annual variations in the I-E scores obtained by United States college students. (Author/RK)

Explores the potential utility of the MMPI 168 with two inpatient medical populations. Correlations and clinically relevant comparisons suggest that the MMPI 168 predicted the standard MMPI with a high degree accuracy. (Editor/RK)

Illusory correlation refers to an erroneous inference a person makes about the relationship between two categories of events. The present findings demonstrate that distortions in judgment can result from the cognitive mechanisms involved in processing information about co-occurring events, at least when the various events co-occur with…

A battery of 28 individually administered tests, comprised of measures derived from the work of Piaget, of simple and complex learning, of language, short-term memory, long-term memory and intelligence were given to 210 children aged 5 to 6 during their first year of schooling. (Editor)

The 1967 and 1973 productivity of female sociologists (measured in terms of number of journal publications) was analyzed and compared to determine if there were any correlation between the improved status of female professionals and their productivity. (JC)

Explores the relationship between sexual abuse and two problem outcomes in adolescents (N=42,568): binge drinking and suicidal ideation. Focused on factors related to problem behaviors among adolescents reporting sexual abuse. Results indicate that adolescents who endured sexual and physical abuse exhibited more problems than those experiencing…

This study investigated the incidence of learning disabilities in 105 children (ages 6-18) with neurofibromatosis Type 1 (NF-1). Results found that nearly 70% of the subjects were academically deficient and 42% met the criteria for learning disabilities. A low incidence of visuospatial-constructional deficits was also found. (Author/CR)

Examines the relationship between stressful life events, occurring in the year previous to the study, and health-related quality of life (HRQOL) among 350 college students. Results indicate that stressful life events were related to poorer HRQOL. Gender did not moderate the relationship between stressful events and HRQOL. (Author/RJM)

Identifies the correlates of current suicidal ideation and past suicide attempts among 555 adolescents. Results indicate that suicidal behavior in delinquent boys was associated with depression and decreased social connection, whereas suicidal behavior in delinquent girls was associated with impulsivity and instability. Current ideation was…

Examined the effect of class size on student performance among 255,665 individual student grades in 6,075 instructional modules held from 1984 through 1994 at Oxford Brookes University (England). Found that although student performance was inversely related to class size, both student performance and class size increased over the course of the…
