Estimating the reproducibility of psychological science

Abstract: Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects were half the magnitude of original effects, representing a substantial decline. Ninety-seven percent of original studies had statistically significant results. Thirty-six percent of replications had statistically significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and if no bias in original results is assumed, combining original and replication results left 68% with statistically significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.

Maternal Depression and Child Psychopathology: A Meta-Analytic Review

Abstract: Although the association between maternal depression and adverse child outcomes is well established, the strength of the association, the breadth or specificity of the outcomes, and the role of moderators are not known This information is essential to inform not only models of risk but also the design of preventive interventions by helping to identify subgroups at greater risk than others and to elucidate potential mechanisms as targets of interventions A meta-analysis of 193 studies was conducted to examine the strength of the association between mothers’ depression and children’s behavioral problems or emotional functioning Maternal depression was significantly related to higher levels of internalizing, externalizing, and general psychopathology and negative affect/behavior and to lower levels of positive affect/behavior, with all associations small in magnitude These associations were significantly moderated by theoretically and methodologically relevant variables, with patterns of moderation found to vary somewhat with each child outcome Results are interpreted in terms of implications for theoretical models that move beyond main effects models in order to more accurately identify which children of depressed mothers are more or less at risk for specific outcomes

IT project managers' construction of successful project management practice: a repertory grid investigation

Abstract: Although effective project management is critical to the success of information technology (IT) projects, little empirical research has investigated skill requirements for IT project managers (PMs). This study addressed this gap by asking 19 practicing IT PMs to describe the skills that successful IT PMs exhibit. A semi-structured interview method known as the repertory grid (RepGrid) technique was used to elicit these skills. Nine skill categories emerged: client management, communication, general management, leadership, personal integrity, planning and control, problem solving, systems development and team development. Our study complements existing research by providing a richer understanding of several skills that were narrowly defined (client management, planning and control, and problem solving) and by introducing two new skill categories that had not been previously discussed (personal integrity and team development). Analysis of the individual RepGrids revealed four distinct ways in which study participants combined skill categories to form archetypes of effective IT PMs. We describe these four IT PM archetypes – General Manager, Problem Solver, Client Representative and Balanced Manager – and discuss how this knowledge can be useful for practitioners, researchers and educators. The paper concludes with suggestions for future research.

Common method variance in advertising research: When to be concerned and how to control for it.

Abstract: In this article we discuss and analyze the critical issues related to common method variance (CMV) that are particularly relevant to advertising research and recommend best practices for assessing the effects of CMV in this domain. Specifically, we cover the development of CMV as a domain-specific methodological concern and the underlying sources of CMV that are likely to operate in cross-sectional survey-based studies in the field of advertising. We discuss in detail the available procedural and statistical techniques that can be applied to control for and/or measure the effects of sources of CMV in a single study and across research domains. In addition, we provide a critical look at how these techniques have been employed in past research and make recommendations for future examinations of CMV in advertising research.
