Articles in this special issue consider different aspects of community-level evaluation research and demonstrate the emerging sophistication and promise of this field. Process evaluation, qualitative research, and meta-analysis are promising new directions for ensuring more appropriate levels of analysis and more appropriate outcomes. (SLD)

A meta-analysis of 97 studies published since 1950 that assessed sex differences in scores on objective and projective dependency tests indicated that women consistently obtained higher dependency scores on objective tests, and men obtained higher scores on projective tests. Findings are discussed in terms of sex role socialization. (SLD)

This meta-analysis builds on past qualitative reviews examining different attributions that observers give for other women's and men's successes and failures. Results suggest the greatest support for the argument that differences in expectations for women's and men's performances on masculine tasks influence the selection of stable or unstable…

Offers instructors a model for presenting meta-analysis to students within an undergraduate experimental psychology course that can be covered in approximately 90 minutes. Discusses the prerequisites for teachers and students, outlines a lecture, and describes an in-class exercise that gives students practice in meta-analytic procedures. Offers an…

A series of meta-analyses identified changes in parent-child conflict during adolescence and moderating factors. Results of age meta-analyses indicated that conflict rate and total conflict declined from early to mid adolescence and from mid to late adolescence; conflict affect increased from early to mid-adolescence. Puberty meta-analyses…

Meta-analysis of the A-not-B error was conducted, using logistic regression, on studies conducted before September 1997. Results replicated earlier findings, with exception that the number of trials at the A location was a significant predictor, and the number of locations was a significant predictor of the proportion of infants who searched…

Conducted meta-analysis of preschool and early elementary school self-esteem instruments, using reliability as criterion variable and different aspects of methodology used in testing an instrument as predictor variables. Found that reliability could be predicted by study setting, number of items in the scale, age of children being studied, method…

Three sets of meta-analyses examined gender effects on children's language use. Each set of analyses considered an aspect of speech that is considered to be gender typed: talkativeness, affiliative speech, and assertive speech. Statistically significant average effect sizes were obtained with all three language constructs. On average, girls were…

Over the past decade activists, academics, and policymakers have devoted a great deal of attention to "environmental equity," or the notion that sources of potential environmental risk may be concentrated among racial and ethnic minorities and the poor. Despite these efforts, the existence and extent of environmental inequities is still…

Research on the effect of suicide stories in the media on suicide in the real world has been marked by much debate and inconsistent findings. Recent narrative reviews have suggested that research based on nonfictional models is more apt to uncover imitative effects than research based on fictional models. There is, however, substantial variation…

A meta-analysis was conducted on all studies of suicide mortality in follow-up studies of schizophrenic patients that presented data for male and female patients separately. The percentage of deaths from suicide was significantly greater for the male schizophrenic patients than for the female schizophrenic patients in studies where both sexes were…

Using data from 8 random assignment studies and employing meta-analytic techniques, this article provides systematic evidence that welfare and work policies targeted at low-income parents have small adverse effects on some school outcomes among adolescents ages 12 to 18 years at follow-up. These adverse effects were observed mostly for school…

Findings from research indicate that teachers participating in online professional development (OPD) activities and programmes have gained, in some way or another, a great deal of teacher competency. In spite of this, no research has been undertaken to systematically identify and acknowledge the types of teacher competencies that are frequently…

This study provides a correlational meta-analysis of 65 independently written or published studies on teacher stress between 1998 and 2003. We measured the relationships between teacher stress and numerous other constructs including coping, burnout, emotional responses, personality mediators, personal support, environmental structure, and…

Narrative reviews have raised several questions regarding the predictive validity of the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 2003) and related scales in institutional settings. In this meta-analysis, the authors coded 273 effect sizes to investigate the association between the Hare scales and a hierarchy of increasingly specific…
