The purpose of this study was to evaluate the effects of supervisory justice on organizational citizenship behavior towards the organization(OCBO) and counterproductive work behavior towards the organization (CWBO), and their psychological mechanism based on the concept of identification and multifoci justice. Specifically, we assumed that supervisory justice has a significant relationship with OCBO and CWBO, and also that this relationship is mediated by supervisory identification and organizational identification. Finally, we expected that supervisor’s organizational embodiment moderates the indirect effect of supervisory justice through organizational identification. The results showed supervisory justice has a significant positive relationship with OCBO and no significant relationship with CWBO. Also, when supervisory identification mediates the relationship of supervisory justice with OCBO and CWBO, supervisory justice has a significant indirect positive relationship with OCBO but no significant relationship with CWBO. On the other hand, when organizational identification mediates, supervisory justice has a significant indirect positive relationship with OCBO and a significant indirect negative relationship with CWBO. Finally, the supervisor’s organizational embodiment moderates the relationship of supervisory justice with OCBO and CWBO, based on the mediation of organizational identification. Specifically, the mediation effect for OCBO was strengthened positively, and the meditation effect for CWBO was strengthened negatively. The results of this study showed a differential effect according to the object in which identification is formed in the process of transferring supervisory justice to behavior toward the organization. Based on these results, we presented the implication and limitations of this study.

Despite the steadily increasing social and academic interest in work meaningfulness, access to this concept as a psychological construct remains insufficient. This study aimed to provide reliable and valid measurement of work meaningfulness for Korean employees by adapting the CMWS, a scale developed by Lips-Wiersma and Wright(2012), into Korean. To verify its validity, data for 516 full-time Korean employees were randomly divided into two groups, and exploratory and confirmatory factor analyses were conducted. The analyses confirmed that the K-CMWS is a seven-factor structural model as shown in the original scale development study. In addition, by using the entire sample, the relationship between the CMWS and major variables related to work and life domains was verified for convergent and criterion validity. Finally, as a result of performing hierarchical regression analysis to verify the incremental validity of the CMWS for major job and organization-related outcome variables. The CMWS confirmed a significant incremental explanatory amount even while controlling for the existing work meaningfulness scales.

Cloud computing (CC) has many benefits, so its use has spread rapidly, particularly in the business sector. An important consideration in the acceptance of CC is whether the CC system is dependable, and it can differ among industry and service type. However, little research has considered the effect of dependability (composed of availability, reliability, security, maintainability) on CC acceptance. Especially, group comparisons between high IT-intensive (Hi-ITi) and low IT-intensive (Lo-ITi) industries have not been reported, nor have comparisons between software-as-a-service (SaaS) and platform-as-a-service (PaaS)/infrastructure-as-a-service (IaaS). This study aims to explore how the dependability of CC affects users’ intent to accept it, with focus on how this intent is affected by intensity of IT use (by industry) and by the type of CC service used. To validate the proposed model, this study applied structural equation modeling and conducted multi-group analysis. A total of 230 business managers in South Korea represent the sample for our study. For the full dataset, the three dependability attributes (availability, reliability, security) do not affect the usefulness of CC, but do affect the ease of use of CC. The usefulness of CC is a determinant for positive intention to accept CC, whereas the ease of use of CC is not. Maintainability is the strongest determinant of CC adoption for the full dataset, and for all individual groups, except those that use SaaS. For Hi-ITi and Lo-ITi industries, results show that managers show no differences in their perceptions of the effect of dependability attributes (availability, reliability, security) on the usefulness and the ease of CC. The absence of such a difference in managers’ perception also applies to the relationship between two core variables of TAM (i.e., perceived usefulness, perceived ease of use) and behavioral intention to accept CC. For SaaS and PaaS/IaaS, managers have different perceptions of security on the usefulness of CC, and the effect of the usefulness of CC on the intention to accept CC. The findings can provide academic researchers and industry practitioners with a differentiated and in-depth perspective on the understanding and the spread of CC.

This study aimed to provide a reliable and valid measure of workaholism for Korean workers. We translated the Multidimensional Workaholism Scale (MWS) into Korean and validated it with a sample of 1020 full-time Korean employees. An exploratory factor analysis revealed a four-factor solution (Study 1; N = 524), and a confirmatory analysis further demonstrated good model fit of the four-factor structure (Study 2; N = 496). The scale’s concurrent and construct validity was supported by positive correlations with other existing measures of workaholism, emotional exhaustion, and work–family conflict (WFC) and by a negative correlation with psychological detachment. Moreover, the MWS demonstrated a moderate association with work engagement, but no significant association with job satisfaction. It further showed significant incremental validity in predicting emotional exhaustion and WFC. The findings support the Korean MWS version’s reliability and validity for measuring workaholism among Korean employees. Theoretical implications for the workaholism literature and practical implications for corporate counselors and human resource practitioners are discussed.

In previous studies the risk perception of future accidents was the main variable likely to affect safe driving. However, findings on the relationship between traffic accident history and risk perception of future accidents have been inconsistent. Moreover, in the case of occupational drivers, work attitudes could be the main factor affecting safe driving. However, no research has been conducted on the direct relationship between traffic accident history and work attitudes. Therefore, present study examined the effect of occupational drivers’ traffic accident history on their risk perception, work attitudes, and unstable driving. Data analysis was based on a self-reported survey of Korean occupational drivers (n = 388) and their official traffic accident records. Results show that traffic accident history was associated significantly with professional pride, job satisfaction, and aggressive driving but not with risk perception of future accidents or job stress. Moreover, all variables measuring unstable driving behavior were significantly related to professional pride, job satisfaction, and job stress. Furthermore, professional pride turned out to mediate the relationship between traffic accident history and current unstable driving. The major finding is that there is no significant relationship between traffic accident history and risk perception of future accidents. Furthermore, traffic accident history has a significant effect on positive variables such as professional pride and job satisfaction but not on negative variables such as job stress. In addition, the significant mediator in the relationship between traffic accident history and current unstable driving behavior was only professional pride.

The role of emotions in all stages of the moral decision-making process has previously been addressed. Little attention, however, has been paid to how the decision-making process is altered when dissimilar types of emotions are suppressed. In four studies, we investigated the effects of suppressing guilt and suppressing shame on the moral decision-making process. Overall results indicate that suppression of guilt and shame influences each of the three stages of the moral decision-making process—judgment, intention, and behavior—differently. In particular, suppressing guilt influenced the three stages consecutively in the moral decision-making process. In contrast, suppressing shame directly influenced moral behavior without traveling through the stages of moral decision-making consecutively. Our results imply distinctive characteristics of guilt and shame—not only in their generative processes but also in their consequences, as well as in the stages of moral judgment, intention, and behavior—when they are suppressed. This finding has important implications for moral psychology, as it points toward a previously overlooked mechanism linking emotions to the moral decision-making process.

This study aims to investigate the characteristics of Korean grit in the workplace. We conducted a cluster analysis to identify gritty workers' subgroups based on their work orientation(job, career, and calling). Organization-related variables such as organizational citizenship behavior, job crafting, job satisfaction, life satisfaction, workaholic, and intention to leave were used to explore potential group-specific differences. Among 361 Korean workers, the gritty worker group (n = 198) was selected based on the median score of grit. Our results show that gritty workers were subdivided into three groups: job-oriented grit(n = 44), neutral-oriented grit(n = 98), calling-oriented grit(n = 56). Calling-oriented grit scored mostly the highest in our study variables except intention to leave. However, job-oriented grit scored the highest in intention to leave, but mostly the lowest in the rest of the study variables. Our results suggest that not only grit but also their work orientation should be considered to improve understanding of grit in the Korean workplace.

Scholarly interest in the relationship between decent work and mental health based on the Psychology of Working Theory has recently increased. This study evaluated the indirect effects of survival, social contribution, and self-determination needs satisfaction on the relationship between decent work and trauma-related mental health among military personnel. We conducted a three-wave survey over 1 year. Results showed that decent work predicted satisfaction of the three basic needs. Additionally, survival needs directly predicted posttraumatic stress disorder symptoms, while social contribution and self-determination needs directly predicted posttraumatic growth. Finally, decent work had a significant indirect effect on posttraumatic stress disorder symptoms via survival needs, whereas decent work had significant indirect effects on posttraumatic growth via social contribution and self-determination needs. Our findings suggest that the more military personnel perceive their work as decent and feel that their three basic needs are fulfilled, the more posttraumatic stress disorder symptoms diminish, and posttraumatic growth increases. We discuss the implications and need for follow-up studies.

PurposeThis study investigated how and when corporate social responsibility (CSR) fosters job seekers' application intention using a mediated moderation model. Specifically, the study explored the positive effect of CSR on job seekers' intention to apply, the moderating role of applicants' calling and the mediating role of value congruence in the relationship between the person and organization.Design/methodology/approachThe study sample consisted of 259 college students in South Korea. A quasi-experimental design and survey were used. Data were analyzed using a regression-based path analysis to test a mediated moderation model.FindingsThe results showed that CSR significantly increased job seekers' application intention, which was moderated by their calling. Furthermore, the interaction between CSR and calling on application intention was fully mediated by the value congruence between person and organization.Practical implicationsThe results suggest that engaging in active CSR can effectively attract job applicants, especially those with a high calling, who are known as qualified workers needed for the organization. The findings can provide a competitive advantage to organizations in this highly competitive environment.Originality/valueThis study contributes to the understanding of the micro-effect of CSR by showing the positive influence of CSR on job seekers' application intention. Further, by evaluating a mediated moderation model, this study advances the field's understanding of the underlying mechanisms of CSR, especially in terms of calling and value congruence.

In this study, we aimed to investigate the two-sided effect of empowering leadership on follower’s job stress by focusing on the potential for positive and negative effects of empowering leadership. Based on the empowerment theory and the role theory of accountability, we examined the mediating effects of self-efficacy and felt accountability and the moderated mediation effects of perceived organizational support(POS) in the relationship between empowering leadership and job stress. A total of 427 Korean employees participated in this study through an online survey. The results show that empowering leadership has indirect effects on job stress mediated by self-efficacy and felt accountability. Specifically, empowering leadership reduced job stress via increased self-efficacy, while increased job stress via increased felt accountability. Evidence was also found of the moderating role of POS: the positive relation between felt accountability and job stress was stronger for those with a low level of POS than those with a high POS. However, the moderating effect of POS was not found in the relationship between self-efficacy and job stress. In addition, the mediating effect of felt accountability was moderated by POS in the relationship between empowering leadership and follower’s job stress. Based on the results, we discuss several implications, limitations, and recommendations for future research.

Ischemic colitis resulting from bowel preparation for colonoscopy is extremely rare, with only a small number of cases with polyethylene glycol having been reported. Here, we present a patient with ischemic colitis after administration of a low-volume oral sulfate solution (OSS). A 49-year-old female without any significant medical history experienced abdominal pain, vomiting, and hematochezia after ingestion of OSS. She complained of severe abdominal pain during colonoscopy, and diffuse edema, hyperemia, friability, and shallow erosions were present on the transverse, descending, and sigmoid colons. A mucosal biopsy revealed mixed lymphoid inflammatory cell infiltration with de-epithelialization, whereas an abdominal CT scan showed submucosal edema on the transverse colon. A diagnosis of ischemic colitis was made. The patient recovered with fluid and antibiotic therapy without significant sequelae. Although OSS is a clinically validated and generally safe bowel preparation agent, ischemic colitis is a rare complication that should be considered.

Drawing on social comparison theory, we explored the effects of the interaction between state goal orientation and directional social comparison on individuals' task performance. In most goal achievement situations, individuals are likely to perform in a social context, which warrants investigation of how the interplay between goal characteristics and surrounding social stimuli influences their performance. We conducted a state-based experiment with 162 undergraduate students, utilizing a 3 (state goal orientation: learning, prove performance, avoid performance) × 2 (social comparison: upward and downward) between-subjects design. When the learning goal orientation or the prove performance goal orientation were manipulated, individuals who had a comparison target performed better than did those who worked by themselves on the given task. In particular, when individuals with a learning goal orientation or a prove performance goal orientation had a downward comparison target their performance improved, whereas those with an avoid performance goal orientation performed better when they had an upward comparison target. Overall the findings explicate the joint roles of state goal orientation and social comparison in influencing task performance.

Employees’ emotional exhaustion caused by their leaders has significant consequences for both individuals and organizations. Identifying the roles of intra-organizational emotional labor is important to prevent employees’ emotional exhaustion. This study examined the relationships between ethical leadership, followers’ emotional labor toward leaders, and emotional exhaustion using Hobfoll’s conservation of resources theory. Data collected from 259 employees working in South Korea were analyzed using regression and SEM. The results indicate that ethical leadership was negatively related to followers’ emotional exhaustion. It is demonstrated that ethical leadership has a significant indirect relationship with followers’ emotional exhaustion through three types of emotional labor strategies, genuine display, faked display, and suppressed display. Through genuine display and suppressed display, ethical leadership had an indirect and negative relationship with followers’ emotional exhaustion, whereas ethical leadership and followers’ emotional exhaustion showed a positive indirect relationship through faked display. We discuss the implications and limitations of this research and future research directions.

Many studies demonstrate that finding meaning in life reduces stress and promotes physical and psychological well-being. However, extant literature focuses on meaning in life among the general population (e.g., college students or office workers) in their daily lives. Thus, this study aimed to investigate the mechanisms of how individuals living in life-threatening and stressful situations obtain meaning in life, by investigating the mediating roles of leisure crafting and gratitude. A total of 465 Army soldiers from the Republic of Korea (ROK) participated in two-wave surveys with a 2-week interval. Structural equation modeling analyses indicated that the direct effects between the search for meaning, presence of meaning, leisure crafting, and gratitude were significant, except for the direct relationship between the search for meaning and the presence of meaning, and between leisure crafting and the presence of meaning. We tested indirect effects using a Monte Carlo approach and found that leisure crafting and gratitude sequentially mediated the relationship between the search for meaning and the presence of meaning. Our findings highlight the importance of the motivation behind searching for meaning, the proactive use of leisure time, and gratitude for individuals in stressful situations and controlled lifestyles. Finally, we discuss the implications and limitations of this research and future research directions.

Despite increasing research on the mechanisms that underlie the relation between perceived overqualification (POQ) and extra-role behaviors, the relation’s affective mechanisms have been understudied. In this study, we focus on the role of job boredom among overqualified workers in order to understand two types of extra-role behaviors: counterproductive work behaviors (CWB) and organizational citizenship behaviors (OCB). Using a sample of white-collar employees in South Korea ( N = 298), we found that job boredom fully mediated the effects of POQ on CWB and OCB after controlling for the effects of state anger and neuroticism. We additionally examined whether career calling moderates the indirect effects of POQ on CWB and OCB via job boredom and found career calling mitigated the negative indirect effect of POQ on OCB via job boredom. However, career calling did not moderate the positive indirect effect of POQ on CWB. Implications of these findings are discussed.
