Workplace ostracism And workplace behaviors: A moderated mediation model of perceived stress and psychological empowerment

Background and objectives: Workplace ostracism research has examined numerous underlying mechanisms to understand the link between workplace ostracism and behavioral outcomes. Ostracism has been suggested to be an interpersonal stressor; however, research has not investigated workplace ostracism from a stress perspective. Therefore, the study investigated the mediating effect of perceived stress for the relationships between workplace ostracism and helping behavior, voicing behavior, and task performance. The study also investigated the moderating effect of psychological empowerment for the relationships between perceived stress and behavioral outcomes.

Design: The study design was a three-wave self-reported questionnaire.

Method: The study sampled 225 full-time employees in South Korea and regression analyses with bootstrapping were conducted to test the moderated mediation models.

Results: The bootstrapped 95% CI around the indirect effects did not contain zero; therefore, perceived stress mediated the relationship between workplace ostracism and helping behavior (–.06), voicing behavior (–.07), and task performance (–.07). Further, the moderated mediation analyses found perceived stress mediated the relationships between workplace ostracism and behavioral outcomes only when individuals perceived low levels of psychological empowerment.

Conclusion: The findings suggest that workplace ostracism is a stressor and psychological empowerment can mitigate the negative effects of ostracism on behavioral outcomes.     

The Incremental Validity of Self-Report and Performance-Based Methods for Assessing Hostility to Predict Cardiovascular Disease in Physicians

We evaluated the utility of an integrative, multimethod approach for assessing hostility-related constructs to predict premature cardiovascular disease (CVD) and premature coronary heart disease (CHD) using participants from the Johns Hopkins Precursors Study, which was designed to identify risk factors for heart disease. Participants were assessed at baseline while in medical school from 1946 to 1962 (M age = 24.6) and have been followed annually since then. Baseline assessment included individually administered Rorschach protocols (N = 416) scored for aggressive imagery (i.e., Aggressive Content, Aggressive Past) and self-reports of 3 possible anger responses to stress. Cox regression analyses predicting morbidity or mortality by age 55 revealed a significant interaction effect; high levels of Aggressive Content with high self-reported hostility predicted an increased rate of premature CVD and CHD, and incrementally predicted the rate of these events after controlling for the significant covariates of smoking (CVD and CHD) and cholesterol (CHD) that were also assessed at baseline. The hostility and anger measures, as well as other baseline covariates, were not predictors of CVD risk factors assessed at midlife during follow-up. Overall, this integrative model of hostility illustrates the potential value of multimethod assessment to areas of health psychology and preventive medicine.     

Detecting Suicide Risk Among College Students: A Test of the Predictive Validity of the Modified Emotional Stroop Task

Detecting suicide risk among nonclinical populations is challenging due to low base rates and the help‐negation tendency of at‐risk individuals. The current longitudinal study investigated the predictive validity of the modified emotional Stroop task (EST) by conducting a follow‐up study of 197 students who participated in a study by Chung and Jeglic (2016). The EST latencies for suicide‐related cues and past suicidal behaviors were the only significant predictors of suicide risk. The findings of this study provide preliminary support for the use of the EST as part of a suicide risk screening battery that could add to the detection of suicide risk.
