This paper delineates the factors that influence the joint impact of attenuation and range restriction on the magnitude of the correlation coefficient. A theoretical framework for the generation of appropriate correction formulas is established. (TJH)

Compared a suicide-completion group to a psychiatric control sample on the 13 traditional MMPI scales, three experimental item pools, and eight profile patterns earlier described as indicative of suicidal tendencies (N=84). The results argue against the use of the MMPI at this time to predict suicide. (JAC)

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…

As school districts integrate evidence-based prevention programs into their daily regime, they may struggle with implementing these programs with fidelity. This is a multi-method, multi-source, retrospective explanatory study of the implementation factors associated with program installation and partial implementation of an evidence-based violence…

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…

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,…

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…

Randomization should be employed whenever possible but the use of carefully controlled nonrandomized data to estimate causal effects is a reasonable and necessary procedure in many cases. (Author/BJG)

This study's purposes were to determine the predictive validity of the Washington Pre-College Test (WPCT) for 16 introductory courses at Yakima Valley College, to demonstrate the importance of a coordinated program of institutional research, and to help the WPCT program gather more data on the students. The predictor intercorrelational table and…

Rescored Wechsler Adult Intelligence Scale (Revised) protocols from 81 normal adults using the Satz Mogel short form procedure. Low correlations between the short forms and full protocols suggest the Satz Mogel procedure can serve only as a gross screening test with normal adults. (JAC)
