Employee attitude surveys: Examining the attitudes of noncompliant employees.

Employees (N? = ?194) from a wide variety of organizations participated in this study aimed at describing the attitudes of individuals who refuse to respond to an employee survey request (noncompliants). Noncompliants, in comparison with those individuals who would comply with the survey request, possessed greater intentions to quit, less organizational commitment, and less satisfaction toward supervisors and their own jobs. Noncompliants also possessed more negative beliefs regarding how their organization handles employee survey data (e.g., does not act on survey data). No significant differences were found for work-related demographic variables, satisfaction with pay, and satisfaction with promotion opportunities. Implications for survey research are discussed along with methods to address nonresponse and noncompliance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

How much calcium to shell out? Eggshell calcium carbonate content is greater in birds with thinner shells,larger clutches and longer lifespans

The avian eggshell is a bio-ceramic structure that protects the embryo. It is composed almost entirely of calcium carbonate and a small amount of organic material. An optimal amount of calcium carbonate in the eggshell is essential for the embryo''s development, yet how the ratio of calcium carbonate to organic matter varies between species has not been investigated. Calcium is a limiting resource for most birds, so its investment in their eggs should be optimized for a bird''s life history. We measured the relative calcium carbonate content of eggshells in 222 bird species and tested hypotheses for how this trait has evolved with the life-history strategies of these species and other traits of their respective egg physiologies. We found that (i) eggshell calcium carbonate content was positively correlated with species having thinner eggshells and smaller than expected eggs relative to incubating parental mass, (ii) species with small mean clutch sizes had lower calcium carbonate content in their eggshells, and (iii) for species with larger clutch sizes, eggshell calcium carbonate content was negatively correlated with their mean lifespan. The pattern of lower eggshell calcium carbonate in longer lived, larger clutched birds suggests that calcium provision to the eggshell has long-term costs for the individual.     

About this issue: Diversity and convergence in the study of psychological trauma.

In this editorial, the editor discusses the diversity of material in the current issue of Psychological Trauma: Theory, Research, Practice and Policy (PT: TRPP). He addresses questions that were raised by the pieces in this issue including ones as fundamental as what constitutes a psychological trauma. The editors believe that it is extremely important that as many facets of this terrain be examined and represented in the pages of PT: TRPP as possible. Only by continually and actively striving to maintain an inclusive perspective can we hope to work toward evolving a reasonable level of understanding of psychological trauma in all its richness and complexity.

A meta-analytic review of the Penn Resiliency Program’s effect on depressive symptoms.

The purpose of this review was to evaluate whether the Penn Resiliency Program (PRP), a group cognitive–behavioral intervention, is effective in targeting depressive symptoms in youths. We identified 17 controlled evaluations of PRP (N = 2,498) in which depressive symptoms had been measured via an online search of PsycINFO, Medline, ERIC, and ProQuest Dissertations and Theses and by requesting data from PRP researchers. We combined effect sizes (ESs; Glass’s d), using random effects models at postintervention and two follow-up assessments (6–8 and 12 months postintervention). PRP participants reported fewer depressive symptoms at postintervention and both follow-up assessments compared with youths receiving no intervention, with ESs ranging from 0.11 to 0.21. Subgroup analyses showed that PRP’s effects were significant at 1 or more follow-up assessments among studies with both targeted and universal approaches, when group leaders were research team members and community providers, among participants with both low and elevated baseline symptoms, and among boys and girls. Limited data showed no evidence that PRP is superior to active control conditions. Preliminary analyses suggested that PRP’s effects on depressive disorders may be smaller than those reported in a larger meta-analysis of depression prevention programs for older adolescents and adults. We found evidence that PRP significantly reduces depressive symptoms through at least 1-year postintervention. Future PRP research should examine whether PRP’s effects on depressive symptoms lead to clinically meaningful benefits for its participants, whether the program is cost-effective, whether CB skills mediate program effects, and whether PRP is effective when delivered under real-world conditions.
