Differences in Emotion Dysregulation and Symptoms of Depression and Anxiety among Illicit Substance Users and Nonusers.

Background: Illicit substance users may rely on mind-altering substances to regulate affect, especially when mental health symptoms are present.

Objectives: In light of the prevalence of illicit substance use and symptoms of depression and anxiety among college students, as well as the affect regulation properties of illicit substances, we sought to examine whether differences in emotion dysregulation, depression, anxiety, and stress exist between illicit substance users and non-users.

Methods: At a large Southwestern U.

Social inequalities and the context of vulnerabilities: HIV/AIDS awareness and prevention knowledge among married women.

Worldwide, socioeconomically disadvantaged women bear disproportionate risks of HIV infection. To examine if the individual and community-level socioeconomic disadvantages further increase their vulnerabilities, we used Bangladesh Demographic and Health Surveys. Between 2004 and 2014, we found pronounced disparities in HIV/AIDS prevention knowledge among women based on their socioeconomic status and community context.

Creating a framework for data sharing in cochlear implant research.

Objectives: To summarize the development process of a national database that was designed to facilitate communication and collaboration, improve care, and create a framework for aggregate data sharing in cochlear implant (CI) research.

Methods: A group of nationally represented, multidisciplinary CI providers cooperated to define a standard set of data elements to incorporate into a database built by them in association with a group of computer scientists and software designers. CI centers across the USA, then, joined the non-profit Auditory Implant Initiative to use the database for their own clinical purposes and to help contribute to the national de-identified dataset for research and analytics.

Moving Beyond Univariate Post-Hoc Testing in Exercise Science: A Primer on Descriptive Discriminate Analysis.

Unlabelled: There has been a recent call to improve data reporting in kinesiology journals, including the appropriate use of univariate and multivariate analysis techniques. For example, a multivariate analysis of variance (MANOVA) with univariate post hocs and a Bonferroni correction is frequently used to investigate group differences on multiple dependent variables. However, this univariate approach decreases power, increases the risk for Type 1 error, and contradicts the rationale for conducting multivariate tests in the first place.

College Students' Physical Activity and Health-Related Quality of Life: An Achievement Goal Perspective.

Purpose: The 2 × 2 achievement goal model, including the mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance goal orientations, has recently been used to explain motivational outcomes in physical activity. This study attempted to examine the relationships among 2 × 2 achievement goal orientations, physical activity, and health-related quality of life (HRQOL) in college students.

Method: Participants were 325 students (130 men and 195 women; Mage = 21.

Neuroprotective effects of curcumin on endothelin-1 mediated cell death in hippocampal neurons.

Objectives: Alzheimer's disease is a progressive neurodegenerative disease characterized by loss of hippocampal neurons leading to memory deficits and cognitive decline. Studies suggest that levels of the vasoactive peptide endothelin-1 (ET-1) are increased in the brain tissue of Alzheimer's patients. Curcumin, the main ingredient of the spice turmeric, has been shown to have anti-inflammatory, anti-cancer, and neuroprotective effects.

Improved Data Reporting in RQES: from volumes 49, 59, to 84.

This commentary provides a review of changes in data reporting in Research Quarterly for Exercise and Sport from Volumes 49 and 59 to 84. Improvements were noted in that all articles reported means, standard deviations, and sample sizes, while most (87%) articles reported an estimate of effect size (ES). Additional reporting recommendations were made about ES for mean differences, use of appropriate estimates of variability, when to use a table or figure, use of multivariate analyses, and power analyses.

Sleep loss and risk-taking behavior: a review of the literature.

Sleep loss is common problem with a wide range of consequences. One possible consequence of sleep loss may be risk-taking behavior (RTB). The present review examined the empirical literature on the relationship between sleep loss and RTB.

Revisiting Interpretation of Canonical Correlation Analysis: A Tutorial and Demonstration of Canonical Commonality Analysis.

In the face of multicollinearity, researchers face challenges interpreting canonical correlation analysis (CCA) results. Although standardized function and structure coefficients provide insight into the canonical variates produced, they fall short when researchers want to fully report canonical effects. This article revisits the interpretation of CCA results, providing a tutorial and demonstrating canonical commonalty analysis.
