Trust and the collection,selection, analysis and interpretation of data: A scientist’s view

Trust is a critical component of research: trust in the work of co-workers and colleagues within the scientific community; trust in the work of research scientists by the non-research community. A wide range of factors, including internally and externally generated pressures and practical and personal limitations, affect the research process. The extent to which these factors are understood and appreciated influence the development of trust in scientific research findings.     

Complexity in the relationships among the subdimensions of extraversion and job performance in managerial occupations

The present study investigated differential relationships, nonlinear relationships, and multiplicative relationships among the subdimensions of extraversion (agency and affiliation) and job performance (getting ahead and getting along) for a sample of 179 managers. We found that: (i) agency was positively related to getting ahead performance, whereas affiliation was unrelated to getting ahead; (ii) agency had an inverted‐U relationship with getting along performance; and (iii) there was a multiplicative effect of agency and affiliation on getting along. The findings provide insight into the nature of the relationship between extraversion and managerial performance, the level of breadth at which to represent these variables for optimal prediction and explanation, and the use of extraversion measures for selection purposes.     

Acculturation and mental health: Current findings and recommendations for future research

Results of existing literature suggest that the relationship between acculturation and mental health is complex. Some studies have found a beneficial association between increased acculturation and mental health, whereas others have found a detrimental association or no relationship at all. We reviewed literature on acculturation and mental health in Hispanics/Latino Americans, Asians/Asian Americans, and other ethnic groups. Results indicate that greater acculturation is associated with increased substance use and abuse. Findings for other disorders and symptoms demonstrate considerable heterogeneity and potential reasons for this variation are provided. Acculturation involves a complex set of processes that appear to have differential impact on mental health outcomes. Critical issues in the measurement of acculturation are discussed, and recommendations for future research are offered.     

Anxiety, anxiety disorders, tobacco use, and nicotine: a critical review of interrelationships

Smoking is highly prevalent across most anxiety disorders. Tobacco use increases risk for the later development of certain anxiety disorders, and smokers with anxiety disorders have more severe withdrawal symptoms during smoking cessation than smokers without anxiety disorders. The authors critically examined the relationships among anxiety, anxiety disorders, tobacco use, and nicotine dependence and reviewed the existing empirical literature. Future research is needed to better understand the interrelationships among these variables, including predictors, moderators, and mechanisms of action. Increased knowledge in these areas should inform prevention efforts as well as the development and improvement of smoking cessation programs for those with anxiety and other psychiatric disorders.
