On the relationship between subjective and objective measures of fatigue

Objective: Objective and subjective methods have been used in the past to assess workplace fatigue, but little is known about correlations between them. We examine correlations between subjective and objective measures, including measures collected in a workplace scenario. Methods: 15 young and 17 older participants were assessed before and after work with four types of fatigue measure: objective physical (posturography), objective mental (psychomotor vigilance task), subjective physical and mental (self-assessment), objective and subjective realistic (oculomotor behaviour, observer-rated facial expression, typing performance). Results: Pre- and post-test scores were analysed with an ANOVA, significant differences were submitted to a factor analysis. It yielded three factors: one representing posturography, the second self-rated mental and physical fatigue and the third observer-rated facial expression. Conclusions: Results advocate the existence of three independent fatigue components: Objective physical fatigue, introspective and extrospective fatigue.

Practitioner Summary: This study analyses correlations between different subjective and objective fatigue markers to better understand the complex nature of workplace fatigue. Measurements were conducted directly at the workplace. Results reveal that fatigue comprises three independent fatigue components: Objective physical fatigue, introspective and extrospective fatigue.     

Prevalence of work-related musculoskeletal and non-musculoskeletal injuries in health care workers: the implications for work disability management

To compare the prevalence of musculoskeletal and non-musculoskeletal injuries in a cohort of workers in Manitoba health care sector, who made injury claims between 2002 and 2012. A retrospective study, using secondary data from WCB Manitoba. Logistic regression was used to determine odds ratios for nature of work-related injuries among different groups of workers. Idiopathic work-related musculoskeletal disorders (WMSD) constituted 74.6% of all the injury claims. Injury risks varied between worker groups, and a significant difference was found within the female group, χ² = 13.4, p = 0.0094, but not among the males. Compared to the married, single workers were more likely to experience traumatic than idiopathic injuries (OR = 1.72, CI, 1.28, 2.29), and much higher risk of traumatic injuries than non-WMSD (OR = 1.93, CI, 1.31, 2.84). Work-related injury risks vary significantly across occupations and worker groups, with idiopathic injuries being higher in high physical tasks.

Practitioner Summary: To compare musculoskeletal and non-musculoskeletal injuries among workers in health care sector, and explore the implications for work disability management. Retrospective study, using workers’ compensation claims data. The risk of idiopathic work-related musculoskeletal disorders continue to be high compared to traumatic and non-musculoskeletal disorders, particularly in tasks that involved high physical activities.     

Verbal abuse from outsiders versus insiders: Comparing frequency, impact on emotional exhaustion, and the role of emotional labor.

Research on aggression from organizational outsiders (customers, clients or patients) has ignored insider-instigated aggression, and has been limited to employees in emotional labor jobs (e.g., social work and customer services). The authors argue that customer-employee interactions have distinct characteristics from organizational insider interactions, and provide two studies to compare the frequency and strain of verbal abuse from customers, supervisors and coworkers. Furthermore, they assess whether customer verbal abuse is only a critical issue for employees in jobs requiring emotional labor, measured with both O*NET job codes and self-reported display rules. With a national random sample of U.S. employees (n = 2446) and a convenience sample of U.S. employees who have customer contact (n = 121), the authors find that verbal abuse from outsiders (1) occurs more frequently than insider verbal abuse, particularly for those with higher emotional labor requirements, and (2) predicts emotional exhaustion over and above insider verbal abuse, regardless of emotional labor requirements. The authors conclude that better integration of customer aggression and insider aggression research is needed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Integrated Fuzzy DEA-ANFIS to Measure the Success Effect of Human Resource Spirituality

Workplace spirituality has gained attention as it is proven to be a contributor to organizational performance improvement. This paper aims to assess the impact of human resource spirituality on the success of organizational strategic change projects. The success of the projects is measured by the well-known criterion of deviation from the planned budget cost. Data collection is based on a questionnaire survey of 252 personnel in 36 large and medium-scale organizational change projects in power industry. The paper proposes an integrated algorithm of fuzzy data envelopment analysis (FDEA) and adaptive network-based fuzzy inference system (ANFIS) for measuring the pure effect of human resource spirituality on the success of organizational change projects in the power industry. It also achieves a verified tool capable of addressing complexity, nonlinearity, ambiguity, and fuzziness for measuring spirituality of human resources in the projects. Results show that spirituality of the project team has a significant effect on project success.     

Evaluation of a workplace technology for mental health assessment: A meaning-making process

This paper describes the results of a summative evaluation conducted to explore the usability and acceptability of an automated telephone-based technology, designed and developed as a screening tool for mental health disorders in the workplace. The system screens employees for symptoms and subsequently provides educational information and referrals to improve mental health and enhance productivity. The qualitative evaluation was a sub-study of a larger randomized controlled trial (RCT). We conducted in-depth interviews with 15 individuals who participated in the RCT and had used the system. A phenomenological theoretical framework was utilized to analyze the narrative data. Results indicated that participants had mostly positive experience with the system and perceived it as a confidential program that allowed them to reflect on their symptoms without inhibition, fear of judgment or embarrassment. We also learned that asking mere questions about mental health symptoms can be a positive, instructive and possibly a restorative experience. There is a likelihood that for many participants, exposure to questions about their emotional and mental distress validated their feelings about their symptoms and was sufficiently compelling to promote help-seeking behavior. This evaluation study demonstrates that computers can be utilized in the workplace as effective screening and educational tools to improve employees’ mental health.     

Triage Drift: A Workplace Study in a Pediatric Emergency Department

This paper presents a workplace study of triage work practices within an emergency department (ED). We examine the practices, procedures, and organization in which ED staff uses tools and technologies when coordinating the essential activity of assessing and sorting patients arriving at the ED. The paper provides in-depth empirical observations describing the situated work practices of triage work, and the complex collaborative nature of the triage process. We identify and conceptualize triage work practices as comprising patient trajectories, triage nurse activities, coordinative artefacts and exception handling; we also articulate how these four features of triage practices constitute and connect workflows, organize and re-organize time and space during the triage process. Finally we conceptualize these connections as an assessing and sorting mechanism in collaborative work. We argue that the complexities involved in this mechanism are a necessary asset of triage work, which calls for a reassessment of the concept of triage drift.     

When openness to experience and conscientiousness are related to creative behavior: An interactional approach.

This study adopted an interactional approach to understanding how 2 of the Five-Factor traits, openness to experience and conscientiousness, are related to creative behavior in the workplace. Openness to experience is theorized to result in high levels of creative behavior and conscientiousness is theorized to result in low levels of creative behavior when the situation allows for the manifestation of the trait influences. More specifically, the authors hypothesized that openness to experience would result in high levels of creative behavior if feedback valence were positive and job holders were presented with a heuristic task that allowed them to be creative. The authors also hypothesized that conscientiousness would result in low levels of creative behavior if supervisors engaged in close monitoring and coworkers were unsupportive. The authors tested their hypotheses in a sample of office workers, and 5 out of the 6 hypotheses were supported. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychosocial predictors of supervisor-, peer-, subordinate-, and service-provider-targeted aggression.

The authors investigate whether known person predictors (trait anger, trait aggression) and situational predictors (perceived interpersonal mistreatment, perceived organizational sanctions against aggression) of supervisor-targeted aggression also predict employee's aggression toward other workplace targets, namely peers, subordinates, and customers' aggression toward service providers. The authors also investigate the moderating impact of situational factors on the relationship between person factors and aggression. Participants (N = 308) were asked whether they had a conflict with their supervisor, a subordinate, a work peer, and/or a service provider in the past 6 months. Different patterns of main and interaction effects emerged across the 4 targets, suggesting the importance of accounting for the target of aggression in workplace aggression research.

Interpersonal Mistreatment in the Workplace: The Interface and Impact of General Incivility and Sexual Harassment.

This article examined the relationships and outcomes of behaviors falling at the interface of general and sexual forms of interpersonal mistreatment in the workplace. Data were collected with surveys of two different female populations (Ns=833 and 1,425) working within a large public-sector organization. Findings revealed that general incivility and sexual harassment were related constructs, with gender harassment bridging the two. Moreover, these behaviors tended to co-occur in organizations, and employee well-being declined with the addition of each type of mistreatment to the workplace experience. This behavior type (or behavior combination) effect remained significant even after controlling for behavior frequency. The findings are interpreted from perspectives on sexual aggression, social power, and multiple victimization. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
