Cross-lagged analyses between gastrointestinal symptoms, psychological distress, and disability in emerging adults.

The gut-brain connection refers to communication between the brain and gastrointestinal (GI) system. Disorders of gut-brain interaction (DGBI) are characterized by GI symptoms that accompany distress and disability. Epidemiological research has suggested DGBI rates in emerging adults are increasing.

TNF-α Regulated Endometrial Stroma Secretome Promotes Trophoblast Invasion.

Successful implantation requires the coordinated migration and invasion of trophoblast cells from out of the blastocyst and into the endometrium. This process relies on signals produced by cells in the maternal endometrium. However, the relative contribution of stroma cells remains unclear.

The trainer matters: Cross-classified models of trainee reactions.

Despite the common belief that "training is only as effective as the trainer providing it" (Osborn, 2018, para. 1), training theory tends to underemphasize the trainer and instead focuses on training content and design as sources of training effectiveness. In this article, we examine whether the role of the trainer should be more central to training theory.

The manipulation of affect: A meta-analysis of affect induction procedures.

Affect inductions have become essential for testing theories of affect and for conducting experimental research on the effects of mood and emotion. The current review takes stock of the vast body of existing literature on affect induction procedures (AIPs; also referred to as mood inductions) to evaluate the effectiveness of affect inductions as research tools and to test theories of affect (e.g.

Motivation to lead: A meta-analysis and distal-proximal model of motivation and leadership.

To understand how motivation to lead (MTL) fits into the broader leadership literature, we present a meta-analytic review of MTL and test a Distal-Proximal Model of Motivation and Leadership. Using a database of 1,154 effect sizes from 100 primary studies, we found that the 3 types of MTL (affective-identity, social-normative, and noncalculative) had a unique pattern of antecedents and were only modestly correlated, indicating that MTL may be best operationalized as three separate motivational constructs instead of as one overarching construct. Further, the 3 MTL types were generally associated with individuals emerging as leaders, engaging in beneficial leadership behaviors (i.

New models of lipopolysaccharide-induced implantation loss reveal insights into the inflammatory response.

Problem: Chronic endometritis, inflammation of the uterizzvvne lining caused by common gram-negative bacterial strains or mycoplasma, has been associated with unexplained implantation failure and infertility. However, limited models of bacteria-induced implantation loss exist to study the molecular changes that occur in vivo. The goal of this study was to provide a new resource to study the process of bacteria-induced inflammation and implantation loss utilizing common experimental models: C57Bl/6 mice and primary human endometrial stromal cells.

Stress and the HPA Axis: Balancing Homeostasis and Fertility.

An organism's reproductive fitness is sensitive to the environment, integrating cues of resource availability, ecological factors, and hazards within its habitat. Events that challenge the environment of an organism activate the central stress response system, which is primarily mediated by the hypothalamic-pituitary-adrenal (HPA) axis. The regulatory functions of the HPA axis govern the cardiovascular and metabolic system, immune functions, behavior, and reproduction.

A meta-analysis of sex and race differences in perceived workplace mistreatment.

Despite the growing number of meta-analyses published on the subject of workplace mistreatment and the expectation that women and racial minorities are mistreated more frequently than men and Whites, the degree of subgroup differences in perceived workplace mistreatment is unknown. To address this gap in the literature, we meta-analyzed the magnitude of sex and race differences in perceptions of workplace mistreatment (e.g.

Leadership training design, delivery, and implementation: A meta-analysis.

Recent estimates suggest that although a majority of funds in organizational training budgets tend to be allocated to leadership training (Ho, 2016; O'Leonard, 2014), only a small minority of organizations believe their leadership training programs are highly effective (Schwartz, Bersin, & Pelster, 2014), calling into question the effectiveness of current leadership development initiatives. To help address this issue, this meta-analysis estimates the extent to which leadership training is effective and identifies the conditions under which these programs are most effective. In doing so, we estimate the effectiveness of leadership training across four criteria (reactions, learning, transfer, and results; Kirkpatrick, 1959) using only employee data and we examine 15 moderators of training design and delivery to determine which elements are associated with the most effective leadership training interventions.

Ethnic identity: Factor structure and measurement invariance across ethnic groups.

Considering a historically diversified (and growing) population in the United States, one's ethnic identification is often an important psychological-as well as social and political-construct because it can serve as a hindrance to interpersonal interaction. Despite the importance of ethnic identity in psychological research, the most widely developed ethnic identity measurement tool, the Multigroup Ethnic Identity Measure (MEIM; Phinney, 1992), lacks consensus regarding its psychometric properties. The purpose of this article is to identify the factor structure of this measure and identify whether it exhibits measurement equivalence/invariance (ME/I) across ethnicities.

Saving lives: A meta-analysis of team training in healthcare.

As the nature of work becomes more complex, teams have become necessary to ensure effective functioning within organizations. The healthcare industry is no exception. As such, the prevalence of training interventions designed to optimize teamwork in this industry has increased substantially over the last 10 years (Weaver, Dy, & Rosen, 2014).

The SPAIC-11 and SPAICP-11: Two brief child- and parent-rated measures of social anxiety.

The Social Phobia and Anxiety Inventory for Children-11 (SPAIC-11) and Social Phobia and Anxiety Inventory for Children's Parents-11 (SPAICP-11) were developed as brief versions of the Social Phobia and Anxiety Inventory--Child and Parent Versions via item response theory (IRT) using child and parent reports of social anxiety. A sample of 496 children was analyzed using IRT analyses, revealing 11 items that exhibit measurement equivalence across parent and child reports. Descriptive and psychometric data are provided for the child, parent, and combined total scores.

Why does self-reported emotional intelligence predict job performance? A meta-analytic investigation of mixed EI.

Recent empirical reviews have claimed a surprisingly strong relationship between job performance and self-reported emotional intelligence (also commonly called trait EI or mixed EI), suggesting self-reported/mixed EI is one of the best known predictors of job performance (e.g., ρ = .

Emotional intelligence is a second-stratum factor of intelligence: evidence from hierarchical and bifactor models.

This article examines the status of emotional intelligence (EI) within the structure of human cognitive abilities. To evaluate whether EI is a 2nd-stratum factor of intelligence, data were fit to a series of structural models involving 3 indicators each for fluid intelligence, crystallized intelligence, quantitative reasoning, visual processing, and broad retrieval ability, as well as 2 indicators each for emotion perception, emotion understanding, and emotion management. Unidimensional, multidimensional, hierarchical, and bifactor solutions were estimated in a sample of 688 college and community college students.

More than g: selection quality and adverse impact implications of considering second-stratum cognitive abilities.

When using cognitive tests, personnel selection practitioners typically face a trade-off between the expected job performance and diversity of new hires. We review the increasingly mainstream evidence that cognitive ability is a multidimensional and hierarchically ordered set of concepts, and examine the implications for both composite test validity and subgroup differences. Ultimately, we recommend a strategy for differentially weighting cognitive subtests (i.

Measurement invariance of the Social Phobia and Anxiety Inventory.

The Social Phobia and Anxiety Inventory (SPAI) is a commonly used self-report measure of social phobia that has demonstrated adequate reliability, convergent validity, discriminant validity, and criterion-related validity. However, research has yet to address whether this measure functions equivalently in (a) individuals with and without a diagnosis of social phobia and (b) males and females. Evaluating measurement equivalence/invariance is necessary in order to determine that the construct of social anxiety is interpreted similarly across these populations.

Emotional intelligence: an integrative meta-analysis and cascading model.

Research and valid practice in emotional intelligence (EI) have been impeded by lack of theoretical clarity regarding (a) the relative roles of emotion perception, emotion understanding, and emotion regulation facets in explaining job performance; (b) conceptual redundancy of EI with cognitive intelligence and Big Five personality; and (c) application of the EI label to 2 distinct sets of constructs (i.e., ability-based EI and mixed-based EI).
