The problem of modeling information systems is studied with a focus on predictability. Syntactic, semantic, and pragmatic criteria are discussed, and 11 references are cited. (Author/BK)

Sought to: (1) identify correlates of biological mothers' decisions to retain or relinquish their babies for adoption; and (2) determine the accuracy with which the decision can be predicted. Correlated data on 20 variables for 190 mothers in Hawaii. (SKC)

Eight indexes for item analyses of small samples of test scores are described. Each index and a corresponding statistical significance test is defined, and tables of critical values of the index and associated right-tail probabilities are given. A computer program for calculating all indexes or any subsets is described. (JD)

Assessed 136 adults diagnosed with major (unipolar) depression for intensity of depressive symptomatology, lethality of suicide ideation, and cognitive variables presumed to mediate depression and suicidality. Results indicated that Beck's Hopelessness Scale combined with Detachment factor of Crandell Cognitions Inventory best predicted depressive…

Past research on the influence of self-efficacy in training has provided mixed results. Key differences between studies pertain to whether past performance is operationalized as a residual variable or as an unadjusted variable and to the type of task used. In this study, the authors conducted and performed a reanalysis to examine the influence of…

The purpose of this study was to examine the temporal patterns of approach-avoidance achievement goals, implicit theories of ability and perceived competence in physical education across the transition from primary to secondary school. We also evaluated the predictive utility of implicit theories and perceived competence with regard to achievement…

This research examined whether the SAT and ACT would predict college grade point average (GPA) after removing g from the tests. SAT and ACT scores and freshman GPAs were obtained from a university sample (N=161) and the 1997 National Longitudinal Study of Youth (N=8984). Structural equation modeling was used to examine relationships among g, GPA,…

A new measure has been developed to assess depressive symptoms, the Beck Depression Inventory for Youth (BDI-Y; J. S. Beck, A. T. Beck, & J. B. Jolly, 2001). This research extends previous validation research of BDI-Y total scores by examining internal consistency and convergent and predictive validity within a school-based sample (n = 859) of…

The purpose of the Youth Level of Service Case Management Inventory (YLS/CMI) is to assess, classify, and assist agencies with developing treatment and service plans according to the offender's criminogenic risk factors. Given the limited research in the predictive validity for this instrument, the current study attempts to examine this issue on a…

Background: There is an urgent need for developing reliable, valid and practical instruments that assess and classify the support needed by persons with disability to function in their chosen living, working and social environments. I-CAN is an instrument that addresses the frequency and level of support needed (not individual skills or deficits)…

The article discusses a scenario-based dieting self-efficacy scale, the DIET-SE, developed from dieter's inventory of eating temptations (DIET). The DIET-SE consists of items that describe scenarios of eating temptations for a range of dieting situations, including high-caloric food temptations. Four studies assessed the psychometric properties of…

A time window is a limited period after an event initially occurs in which additional information can be integrated with the memory of that event. It shuts when the memory is forgotten. The time window hypothesis holds that the impact of a manipulation at different points within the time window is nonuniform. In two operant conditioning…

Many couples suffer a decline in marital satisfaction over the transition to parenthood. Previous research indicated that a couple's relational efficacy (a measure of a couple's belief in their ability to solve problems) before the birth of their first child was one of the strongest predictors of their marital satisfaction after the birth. This…

APTITUDE MATURATION RESEARCH COMPLETED IN 1959 MADE IT POSSIBLE TO EXTEND THE USE OF THE GENERAL APTITUDE TEST BATTERY (GATB) TO EDUCATIONAL VOCATIONAL COUNSELING OF NINTH AND 10TH GRADERS. IN AN EFFORT TO EXTEND ITS USE FURTHER, THIS STUDY WAS MADE TO DETERMINE THE EXTENT TO WHICH THE OCCUPATIONAL TEST NORMS VALIDATED ON ADULT SAMPLES PREDICT THE…
