Differences between underachieving and nonunderachieving study skills students were found on measures of study skills knowledge and an extraversion-introversion personality dimension. Nonunderachievers reported greater study skills knowledge but not greater study skills use than underachievers. Findings were attributed to differences in…

In a recent article in this journal (EJ 130 391) Siegel and Bergman described a "miniature job training and evaluation" approach to performance prediction. This research highlights their methodology's strengths and weaknesses in light of standard procedures recommended in developing any set of predictors. (Author/RK)

Argues that statistical analysis of the potential distinctiveness of near-merged contrastive pairs must simultaneously take into account several acoustical dimensions. Discriminant analysis of the speech of five Utah speakers distinguished near-merged contrasts but not homophones, suggesting that discriminant analysis is useful in assessing…

Discusses three topics related to interpretation of discriminant analyses (DA's): (1) partial F ratios and partial Wilks's lambdas for predictor variables in standard, step-down, and stepwise DA's; (2) relation of goals of classification to definition/evaluation of classification rules; and (3) significance tests for total hit rates in internal…

Standardization procedures in discriminant analysis are discussed. Three leading software packages--SPSSX, BMDP, and SAS--are compared in terms of their calculations of unstandardized and standardized discriminant coefficients. Estimation procedures are described for each. Arguments are presented for within-group, rather than total, variance…

Examined discriminant validity of Family-of-Origin Scale (FOS) with 60 self-defined adult children of alcoholics (ACOAs) and 64 college students. ACOAs obtained significantly lower scores on 10 FOS subscales, 2 larger dimensions of Autonomy and Intimacy, and global score. Discriminant function correctly classified nearly 88% of sample. Findings…

Describes exploratory and confirmatory analyses of verbal-performance procedures to illustrate concepts and procedures for analysis of correlated factors. Argues that, based on convergent and discriminant validity criteria, factors should have higher correlations with variables that they purport to measure than with other variables. Discusses…

A study of the differentiation of styles in identity formation with high school students found a group that displays an evolutive style of identity formation. Characteristics of this style are examined, focusing on the significance of the evolutive style. (SLD)

Assesses discriminate validity of teacher judgments in differentiating various groups of students who are at risk for learning difficulties based on referral to School Study Teams (SSTs). Large differences are found between controls and at-risk groups. Results from cross-validated discriminate function analyses shows teacher judgment correctly…

Functional analysis methods were used to monitor medication used to reduce vocal and physical tics of a child with Tourettes Syndrome. Post-medication results demonstrated a reduced level of tics by the participant. Although preliminary, the findings suggest that functional analysis methods can be used to monitor the effects of medication in…

The ElemenOE is a Likert-scaled observation checklist developed in this study to measure 5 personality characteristics in elementary school children, with predictive validity for identifying giftedness. The characteristics, named "overexcitabilities," are described within the context of Dabrowski's Theory of Positive Disintegration. Five…

Purpose: We identify environmental and organizational predictors that best discriminate between formal continuous quality improvement (CQI) adopters and nonadopters in nursing homes (NHs) and create a diagnostic profile for facility administrators and policy makers to promote CQI. Design and Methods: We performed a cross-sectional survey of…

The authors examined the Trauma Symptom Inventorys (TSI) ability to discriminate 88 student post-traumatic stress disorder (PTSD) simulators screened for genuine PTSD from 48 clinical PTSD-diagnosed outpatients. Results demonstrated between-group differences on several TSI clinical scales and the Atypical Response (ATR) validity scale.…

Using the personal income tax filing as an example of e-governmental services, this paper seeks to develop an understanding of the factors that influence citizens' adoption of electronic tax-filing services based on empirical data gathered from a large-scale nationwide survey. The taxpayers' satisfaction and usage intention regarding the use of…

In this article, we examine the extent to which children with autism and children with learning difficulties can be discriminated from their responses to different patterns of sensory stimuli. Using an adapted version of the Short Sensory Profile (SSP), sensory processing was compared in 34 children with autism to 33 children with typical…
