Most reading time studies using naturalistic texts yield data sets characterized by a multilevel structure: Sentences (sentence level) are nested within persons (person level). In contrast to analysis of variance and multiple regression techniques, hierarchical linear models take the multilevel structure of reading time data into account. They…

Results from a survey of college students (N = 2,008) indicate that most disapproved of a major riot that had occurred on their campus but most also felt that the university was excessively restricting alcohol, and almost half of them enjoyed the riot. The major predictor of condoning the riot was objecting to restrictions against alcohol.…

The computation and reporting of effect size estimates is becoming the norm in many journals in psychology and related disciplines. Despite the increased importance of effect sizes, researchers may not report them or may report inaccurate values because of a lack of appropriate computational tools. For instance, Pierce, Block, and Aguinis (2004)…

This study investigated the influence of two role stressors--role ambiguity and role conflict--on previously established relationships between mentoring activities--vocational support, psychosocial support, and role modeling--and prominent job attitudes. Full and partial mediation models were tested with a sample of 355 proteges. Results showed…

Although a powerful technique, the partialling of independent variables from one another in the context of multiple regression analysis poses certain perils. The present article argues that the most important and underappreciated peril is the difficulty in knowing what construct an independent variable represents once the variance shared with…

This study examined the hypothesis that religiosity would be differentially related to six types of adolescent prosocial behaviour, and that these relations would be mediated by the prosocial value of kindness. Self-report data were collected from 142 high school students (63 per cent female; 91 per cent White; M age = 16.8, S = .80). Religiosity…

Using data from a community sample of youth (N = 1,458; ages 9?17), this study assessed the association between adolescent substance use/abuse and suicidal behaviors. Suicide attempts were strongly associated with alcohol abuse and dependence, followed by frequent cigarette smoking. The associations remained significant even after controlling for…

Homicidality rates have been shown to be more prominent among persons diagnosed with mental disorders as compared to the general population. However, the role that anxiety plays in homicidal ideation and intent is poorly understood. This study investigated predictors of homicidal intent, thought, or plan in an adult population of psychiatric…

Provided is a commentary on articles written for a special section on temperament and childhood disorders. Temperament's contributions to the development of childhood disorders are considered both generally and specifically. Questions are raised about the use of terminology in the field, particularly the term difficult. Differentiation of outcomes…

This study evaluated predictors of adolescent delinquency severity (11 to 17 years of age) among a diverse group of preadolescent boys with attention deficit hyperactivity disorder (ADHD; n = 100) and age-matched comparison boys (n = 75). During childhood, baseline assessments yielded diagnostic information, and naturalistic summer programs…

Suppressor situations occur when the simultaneous inclusion of two predictors improves one or both validities. A common allegation is that suppressor effects rarely replicate and have little substantive import. We present substantive examples from two established research domains to counter this skepticism. In the first domain, we show how…

The Oklahoma City bombing in April 1995 was an act of terrorism that had many potential influences on the city and state, including influences on families. We analyzed divorce data from 1985 to 2000 for all 77 counties in Oklahoma to assess the divorce response to the Oklahoma City bombing. Our prediction was that divorce rates in Oklahoma would…

Much research on sexual deviance on university and college campuses is limited by its narrow focus on group affiliation and leads to much speculation and conjecture. This article suggests that an alternative explanation is more suitable for explaining such an important and complex problem on college campuses. It argues that prior deviance serves…

In this study we examined the relationships among lesbian identity development, perceptions of campus climate, and vocational development of 192 undergraduate lesbian women. Results indicated the combination of lesbian identity development phases and campus climate accounted for significant variance in two measures of vocational development.…

This longitudinal study examined risk assessment dimensions and practices used by the Orange County (California) Juvenile Probation Office to identify youth most at risk of re-offending. Results indicated that the risk assessment was not equally predictive for females and males. The use of gender specific norms or gender neutral assessments and…
