Using mixture models with known class membership to address incomplete covariance structures in multiple‐group growth models

Multi‐group latent growth modelling in the structural equation modelling framework has been widely utilized for examining differences in growth trajectories across multiple manifest groups. Despite its usefulness, the traditional maximum likelihood estimation for multi‐group latent growth modelling is not feasible when one of the groups has no response at any given data collection point, or when all participants within a group have the same response at one of the time points. In other words, multi‐group latent growth modelling requires a complete covariance structure for each observed group. The primary purpose of the present study is to show how to circumvent these data problems by developing a simple but creative approach using an existing estimation procedure for growth mixture modelling. A Monte Carlo simulation study was carried out to see whether the modified estimation approach provided tangible results and to see how these results were comparable to the standard multi‐group results. The proposed approach produced results that were valid and reliable under the mentioned problematic data conditions. We also present a real data example and demonstrate that the proposed estimation approach can be used for the chi‐square difference test to check various types of measurement invariance as conducted in a standard multi‐group analysis.     

The Role of Social Toxicity in Responses to a Slowly-Evolving Environmental Disaster: The Case of Amphibole Asbestos Exposure in Libby,Montana, USA

Experiencing a disaster has significant negative effects on psychological adjustment. Case study accounts point to two consistent trends in slowly-evolving environmental disasters: (a) patterns of negative social dynamics, and (b) relatively worse psychological outcomes than in natural disasters. Researchers have begun to explicitly postulate that the social consequences of slowly-evolving environmental disasters (e.g., community conflict) have their own effects on victims’ psychological outcomes. This study tested a model of the relationship between those social consequences and psychological adjustment of victims of a slowly-evolving environmental disaster, specifically those whose health has been compromised by the amphibole asbestos disaster in Libby, MT. Results indicate that experiencing greater community conflict about the disaster was associated with greater family conflict about the disaster which, in turn, was associated with greater social constraints on talking with others about their disease, both directly and indirectly through experiencing stigmatization. Experiencing greater social constraints was associated with worse psychological adjustment, both directly and indirectly through failed social support. Findings have implications for understanding pathways by which social responses create negative effects on mental health in slowly-evolving environmental disasters. These pathways suggest points for prevention and response (e.g., social support, stigmatization of victims) for communities experiencing slowly-evolving environmental disasters.     

Toward an Inductive Theory of Stayers and Seekers in the Organization

This study takes a person-centered approach to enhance our understanding of job search and intentions to leave among currently employed individuals. Four categories of seekers and stayers in the organization were identified based on their unique patterns of turnover intentions, behaviors, and reasons: Embedded Stayers, Detached Stayers, Dissatisfied Seekers, and Script-Driven Seekers. We theorize that these prototypes are conceptually differentiated by two dimensions—the direction of action and the concreteness of plans. We also found meaningful associations between the probability of cluster membership and a variety of individual difference variables such as job satisfaction, motivational forces, and personality dispositions. Findings from the present study provide some useful insights for theory building and future empirical studies on individual differences in whether and why people intend to leave or stay in their jobs.     

The Incremental Validity of Honesty–Humility Over Cognitive Ability and the Big Five Personality Traits

The present study examines the incremental validity of Honesty–Humility (H-H), a measure of the tendency to be fair and genuine in dealing with others, for supervisory ratings of job performance (including both task and contextual performance) over cognitive ability and the Big Five personality traits. Specifically, we explore the incremental validity of H-H in predicting contextual performance. Results based on 217 South Korean military officer candidates are consistent with previous conclusions that Conscientiousness is the strongest predictor of contextual performance and that cognitive ability is the strongest predictor of task performance. More important, our results reveal that H-H offers moderate incremental validity for contextual performance but no incremental validity for task performance over the effects of cognitive ability and the Big Five personality traits.     

Regulatory focus as a predictor of omission bias in moral judgment: Mediating role of anticipated regrets

Omission bias occurs when people are more reluctant to accept negative consequences caused by their actions than by their inaction. Recent research on omission bias in decision‐making has found evidence for individual differences, thus indicating that some people are more likely to show omission inclination than others. The present research aims to explore the role of regulatory focus as individual difference variables in omission bias. Moreover, we examine whether anticipated regret mediates the relationship between regulatory focus and moral judgement. Moral judgement tasks utilized include: (i) moral dilemma scenarios (Study 1); and (ii) ethical scenarios embracing apparent legal rule violations (Study 2). The results of both studies show that only prevention focus is significantly related to omission bias in moral judgement. Specifically, this relationship holds regardless of the nature of the ‘omission’ (whether they are deontological or utilitarian). In addition, anticipated regret/guilt for action was found to mediate the relationship between prevention focus and omission bias. Implications and limitations are discussed based on the results of the current study.     

Morally Judging Entertainment: A Case Study of Live Tweeting During Downton Abbey

In this study, we propose that the massive, unsolicited, real-time data generated by social media might provide media psychologists with new paths for examining the role that morality and moral thinking play during the consumption of entertainment. Our broad goal was to explore a potentially new methodological approach to the study of morality and media and to offer an initial case study in applying that approach. The case study examined if, and if so how, viewers used Twitter to express their moral thoughts during the Season 3 finale of Downton Abbey. Based on moral foundation theory and affective disposition theory, we derived and examined a set of propositions. Specifically, we observed and discussed the importance of tweets (a) reflecting language from five moral domains, (b) for a beloved character who suffers pain and loss, and (c) about a character who regularly violates moral norms. We conclude that social TV analysis offers a promising new way for researchers to explore issues of morality and media reception.
