The issue of school leadership instability and how it affects schools and student achievement has been studied. The question of how to predict turnover of the principal remains an unknown. The purpose of this research was to search for possible relationships between certain contextual variables and principal turnover and to test the independent…

This study investigated longitudinal associations between externalizing behavior and dysfunctional eating attitudes and behaviors. Participants were girls drawn from the community-based Minnesota Twin Family Study and assessed at ages 11, 14, and 17. Cross-sectional correlations indicated that the strength of the associations between externalizing…

Despite the importance of good lecture notes to test performance, very little is known about the cognitive processes that underlie effective lecture note taking. The primary purpose of the 2 studies reported (a pilot study and Study 1) was to investigate 3 processes hypothesized to be significantly related to quality of notes: transcription…

Using a representative sample of low-income, primarily minority adolescents (N=647, aged 10-14 years at Wave 1), this study examined bidirectional longitudinal relations between nonresident father involvement, defined as contact and responsibility for children's care and behavior, and adolescent engagement in delinquent activities. Autoregressive…

Reports an error in "Effect of anxiety reduction on children's school performance and social adjustment" by Jeffrey Wood (Developmental Psychology, 2006[Mar], Vol 42[2], 345-349). The byline and author note should have included the author's middle initial, J. Thus, the byline and author note should refer to "Jeffrey J. Wood." The correction is…

Objective: Controversy abounds regarding the process by which child sexual abuse victims disclose their experiences, particularly the extent to which and the reasons why some children, once having disclosed abuse, later recant their allegations. This study examined the prevalence and predictors of recantation among 2- to 17-year-old child sexual…

Monte Carlo methods were used to investigate the effect of misspecification of the second level in a two-level hierarchical linear model (HLM). Sample composition, heterogeneity of the group size, level of intraclass correlation, and correlation between second-level predictors were manipulated. Each of 20 generated data sets was analyzed nine…

A study presents a perceptual model of thinking called the "Six Thinking Hats" and argumentativeness as a predictor of response to the model. The "Six Thinking Hats" model creates six artificial contexts for thinking, corresponding to the primary thought modes of objective, subjective, critical, and creative thinking, within a…

The increased use of multiple regression analysis in research warrants closer examination of the coefficients produced in these analyses, especially ones which are often ignored, such as structure coefficients. Structure coefficients are bivariate correlation coefficients between a predictor variable and the synthetic variable. When predictor…

A growing body of literature documents the frequency and magnitude of adolescent suicide. Because of the difficulties inherent to the nature of suicide, ascertaining the actual frequency of suicidal completions, attempts, and ideation is extremely difficult. Although there have been many attempts to isolate the correlates and causal factors of…

Suppressor effects are considered one of the most elusive dynamics in the interpretation of statistical data. A suppressor variable has been defined as a predictor that has a zero correlation with the dependent variable while still, paradoxically, contributing to the predictive validity of the test battery (P. Horst, 1941). This paper explores the…

A study examined the role played by gender and communication content in the leadership emergence process in small, task-oriented groups. Six hours of transcribed group interaction from a sample of the group deliberations of 6 mixed-sex groups of college students (n=27) engaged in a 4-month-long decision-making project served as the database for…

Women exhibit a wide range of responses to a sexual assault. This study focused on two factors that may either hinder or facilitate postrape recovery and which are potentially modifiable: (1) causal attributions; and (2) coping strategies. Rape survivors (n=105) seen at a sexual assault resource service in Minneapolis, Minnesota, completed…

While surveys have identified instructional design competencies, there has been virtually no systematic research of alternative means for assessing professional competence in this area. This paper reports on a study which investigated the question of whether a multiple-choice, paper and pencil test can validly discriminate between levels of…

To identify parental predictors of child maltreatment, 1,400 prenatal patients were interviewed about their attitudes, experiences, and knowledge of childrearing. Interviews with mothers assessed (1) self-perception of mothers' nurturing as children; (2) personality factors of self-image, isolation, and tolerance to stress; (3) social support…
