OBJECTIVES: In the context of a group randomized field trial, we evaluated whether parents who participated in a workplace intervention, designed to increase supervisor support for personal and family life and schedule control, reported significantly more daily time with their children at the 12-month follow-up compared with parents assigned to the...

Introduction The DoD has prioritized programs to optimize readiness by enhancing resilience of its service members. Problematic anger in the military is an issue that impacts psychological well-being and resilience. Leader support is a potential tactic for reducing anger and its effects. Currently military resilience training is focused on individu...

The high, and still rising, rate of loneliness is a threat to public health (Office of the Surgeon General, 2023), with negative mental and physical health consequences (e.g., Holt-Lunstad, 2021). Given that loneliness is a risk factor for poor mental health, efforts to address loneliness are urgently needed. Workplaces can facilitate an employee’s...

Purpose We examined the impact of a leadership support training intervention implemented prior to the coronavirus (COVID-19) pandemic on support behaviors specific to COVID-19 during the pandemic. Primary intervention targets (i.e. family-supportive supervisor behaviors and sleep leadership behaviors) were explored as mediators between the interven...

The attention to workplace mental health is timely given extreme levels of burnout, anxiety, depression and trauma experienced by workers due to serious extraorganizational stressors – the COVID-19 pandemic, threats to climate change, and extreme social and political unrest. Workplace-based risk factors, such as high stress and low support, are con...

Objectives. To examine whether workplace interventions to increase workplace flexibility and supervisor support and decrease work–family conflict can reduce cardiometabolic risk. Methods. We randomly assigned employees from information technology (n = 555) and long-term care (n = 973) industries in the United States to the Work, Family and Health N...

We tested the effects of a randomized controlled trial Total Worker Health® intervention on workplace safety outcomes. The intervention targeted employee sleep at both the supervisor-level (e.g., sleep-specific support training) and employee-level (e.g., sleep tracking and individualized sleep feedback). The intervention components were developed u...

The high, and still rising, rate of loneliness is a threat to public health (U.S. Surgeon General, 2023), with negative mental and physical health consequences (e.g., Holt-Lunstad, 2021). Efforts to address loneliness are urgently needed. Workplaces can facilitate an employee’s sense of belonging and inclusion through leadership training, which can...

In this Cambridge Companion, global thought leaders in the fields of workplace stress and well-being highlight how theory and research can improve employee health and well-being. The volume explains how and why the topics of workplace stress and well-being have evolved and continue to be highly relevant, and why line managers have great influence o...

The military has allocated extensive resources to improve service member resilience in an effort to decrease the impact of stressors on health and well-being. Previous research has linked resilience to various positive outcomes (e.g., physical and mental health, job satisfaction) and has established that service members face unique and challenging...

This study assessed the associations of employee’s perceptions of family-supportive supervisor behaviors (FSSB) and their psychological distress across four occupational populations (n = 3778): Information technology; healthcare; military-connected Veterans; and National Guard service members. Data were gathered and analyzed from four larger archiv...

Existing research consistently shows that informal workplace support, such as family‐supportive supervisor behaviors (FSSB), are more effective at reducing work–family conflict than formal organizational supports. The purpose of this study is to integrate propositions from the stereotype content model and social role theory to understand how family...

Although evidence has been mounting that supervisor support training interventions promote employee job, health, and well-being outcomes, there is little understanding of the mechanisms by which such interventions operate (e.g., Hammer et al., 2022; Inceoglu et al., 2018), nor about the integration of such organizational-level interventions with in...

Very few studies to date have examined immigrant workers’ (i.e., workers who were not born in the United States) experiences of the work-family interface. In a sample of healthcare workers across two time points, the present study evaluates the role of different family-specific resources for immigrant workers compared to native-born workers (i.e.,...

Soldiers in combat often experience life-threatening events, whereas on the home-front soldiers typically proceed without corporeal risk. However, soldiers are now exposed to the threat of death off the battlefield as the COVID-19 pandemic evokes fear of death (thoughts of one's own death/dying) and death anxiety (fear of others who are dead/dying;...

This chapter focuses on the role of leadership in hiring and retaining military veterans in civilian organizations—both the leadership experience and abilities a veteran brings to an employer and the importance of civilian workplace supervisors. Supervisors are key in supporting and recognizing the unique knowledge, skills, and abilities that veter...

Objective: The aim of this study was to present safety, health and well-being profiles of workers within five occupations: call center work (N = 139), corrections (N = 85), construction (N = 348), homecare (N = 149), and parks and recreation (N = 178). Methods: Baseline data from the Data Repository of Oregon's Healthy Workforce Center were used. M...

Workplace supportive supervisor interventions offer an effective, though underutilized mechanism to bolster employee well‐being, which may have important benefits particularly for understudied groups such as military veterans in the civilian workforce. The present study employed a two‐wave daily diary study to test the effectiveness of a supportive...

Training interventions that target supervisors as a mechanism to initiate change in employee health, well-being, and work outcomes are increasingly common, but research has largely neglected to evaluate the impact that these interventions have on supervisors themselves. Relying on conservation of resources theory (Hobfoll 1989, 2001), this study so...

Objective: The health-promoting influence of supportive close relationships has been extensively documented, yet the mechanisms of this effect are still being clarified. Leading researchers have theorized that examining particular interpersonal interactions and the mediating intrapersonal processes they facilitate is the key to understanding how c...

Prior research has demonstrated the impact of military sexual trauma (MST) on health and well-being. However, little empirical work has been published identifying protective factors for women who have experienced MST. We examined the impact of two different forms of MST, harassment-only and assault MST, on PTSD symptoms and social functional impair...

Employee family relationships have been increasingly tied to job outcomes and are known to be a strong predictor of employee health and well-being. As such, taking steps toward uncovering actionable tools organizations can implement to foster improvements in family relationship quality is important and should not be overlooked in occupational healt...

High rates of alcohol use have been documented within military personnel and spouses. However, scant research has investigated alcohol consumption behaviors in matched couples or nonclinical veteran samples. The manner in which couples influence one another’s drink- ing remains unclear. The current study examined hazardous drinking scores and drink...

Workers bear a heavy share of the burden of how countries contend with COVID-19; they face numerous serious threats to their occupational health ranging from those associated with direct exposure to the virus to those reflecting the conflicts between work and family demands. Ten experts were invited to comment on occupational health issues unique t...

Objective: Establishment of core competencies for education and training of professionals entering the emerging field of Total Worker Health®. Methods: Compilation and distillation of information obtained over a five-year period from Total Worker Health symposia, workshops, and academic offerings, plus contributions from key stakeholders regardi...

In this paper we summarize the results of a ten-country study that explored the role of culture in the work-family (W-F) interface, and we use the results to suggest relevant work-family interventions for organizations. Some of the study’s findings supported previous research and are applicable worldwide while other findings regarding employees’ ex...

Healthcare is the fastest growing occupational sector in America, yet patient care workers experience low job satisfaction, high turnover, and susceptibility to poor sleep compared to workers in other jobs and industries. Increasing schedule control may be one way to help mitigate these issues. Drawing from conservation of resources theory, we eval...

The present study evaluates the effectiveness of a supervisor support training programme on both supervisor attitudes and employee sleep and stress outcomes by drawing on a multi‐level rigorous randomized controlled trial in 35 organizations. Utilizing theory from the social support and training literatures, the purpose of the current study was to...

Sleep is critical to employees' health and well-being, safety, and performance at work. Sleep leadership refers to supervisor behaviors that aim to improve employees' sleep, such as showing concern for the quantity and quality of employees' sleep. Using a sample of 180 employees and their 91 supervisors working as full-time National Guard military...

The Safety and Health Improvement Program (SHIP) was designed to increase workers’ safety and health using supervisor/leadership training. SHIP was implemented and evaluated in a cluster randomized controlled trial with 20 supervisors and 292 construction crew members representing a high-risk industry. The intervention had three components: (1) com...

Healthy employee sleep is important for occupational safety, but the mechanisms that explain the relationships among sleep and safety-related behaviors remain unknown. We draw from Crain, Brossoit, and Fisher’s (in press) work, nonwork, and sleep (WNS) framework and Barnes’ (2012) model of sleep and self-regulation in organizations to investigate t...

Men in the United States are increasingly involved in their children’s lives and currently represent 40% of informal caregivers to dependent relatives or friends aged 18 years and older. Yet much more is known about the health effects of varying family role occupancies for women relative to men. The present research sought to fill this empirical ga...

Background: Posttraumatic stress disorder (PTSD) and problematic alcohol use commonly co-occur among military service members. It remains critical to understand why these patterns emerge, and under what conditions. Objectives: This study examined whether PTSD symptoms (PTSS) and alcohol involvement (quantity and frequency of use, heavy episodic...

This study examines the process through which family interference with work (FIW) negatively relates to safety performance in two unique samples from high-risk industries. Using a sample from the construction industry, Study 1 finds that FIW is related to employees’ workplace cognitive failures, which in turn, were a significant predictor of safety...

Among couples, sleep is theorized to be a dyadic process, within which relationship quality exerts a large influence (Troxel, Robles, Hall, & Buysse, 2007). In turn, research has shown that capitalization, or positive-event disclosure, influences relationship quality. The benefits of capitalization, however, are contingent on the receipt of a suppo...

The notion of constellations is central to many occupational health theories; empirical research is nevertheless dominated by variable-centered methodologies. Guided by the job demands-resources framework, we use a person-centered longitudinal approach to identify constellations of job demands and resources (task-based and time-based) over time tha...

This randomized controlled trial involved the development and evaluation of a supervisor support training intervention in the civilian workforce called VSST: Veteran-Supportive Supervisor Training. A theoretically based intervention in the workplace is critical to ensuring a smooth transition for service members and their families to civilian life,...

Although calls for intervention designs are numerous within the organizational literature and increasing efforts are being made to conduct rigorous randomized controlled trials, existing studies have rarely evaluated the long-term sustainability of workplace health intervention outcomes, or mechanisms of this process. This is especially the case wi...

This study examined predictors of alcohol use (i.e., drinking quantity and frequency) in a sample of correctional officers (COs). More specifically, based on the idea of drinking to cope, we predicted an indirect effect of emotional demands at work on COs’ drinking through employee burnout (i.e., exhaustion and disengagement). We further proposed t...

This study examines the role of negative work rumination and recovery experiences in explaining the association between workplace incivility and employee insomnia symptoms. Drawing on the perseverative cognition model of stress and the effort–recovery model, we hypothesize a moderated mediation model in which workplace incivility is associated with...

Despite efforts of thousands of post-9/11 veterans to reintegrate into the civilian workforce, little research attention has focused on organizational support for their needs. Using data from a sample of nearly 500 post-9/11 veterans and service members employed in a variety of organizations, we developed and validated a measure of veteran-supporti...

This study sought to understand the age-based differences in the usefulness of job resources in relation to employee stress. We extended Conservation of Resources theory by integrating two lifespan development models (Selection-Optimization-Compensation and Socio-emotional Selectivity theories) to argue that job resources would be differentially be...

Objective: Work and family stressors may be associated with elevated cardiovascular risk factors. Methods: To assess the effects of work-to-family conflict (WTFC) on biomarkers of cardiometabolic risk, we examined 1524 extended care employees over 18 months and estimated multilevel linear models that accounted for the nested nature of the data. Res...

Although evidence is growing in the occupational health field that supervisors are a critical influence on subordinates’ reports of family supportive supervisor behaviors (FSSB), our understanding is limited regarding the antecedents of employee’s FSSB perceptions and their lagged effects on future health and work outcomes. Drawing on a positive jo...

Employees in security-related occupations are expected to be alert and on guard at work in order to stay safe and complete their work tasks (e.g., police, military, corrections). This study introduces the concept of work-related hypervigilance (WHV) as an experience at work that sustains cognitive and physiological activation among employees and is...

Objective: Hazardous drinking in the armed forces is a significant problem. Alcohol use motivations, known risk factors for problem drinking, have been underexplored in this population. Our study extends knowledge about drinking motives among current and former U.S. service members and provides recommendations on their utility in identifying alcoh...

Our study extends knowledge about drinking motives among current and former U.S. service members and provides recommendations on their utility in identifying alcoho...

Although job stress models suggest that changing the work social environment to increase job resources improves psychological health, many intervention studies have weak designs and overlook influences of family caregiving demands. We tested the effects of an organizational intervention designed to increase supervisor social support for work and no...

The Study for Employment Retention of Veterans (SERVe) is focused on improving the health, well-being, and employment retention of military service members who are now civilian employees. The SERVe sample was comprised of employed post 9/11 service members who represent 3 categories of service members: (a) separated active duty service members (n =...

An increasing number of adults, both men and women, are simultaneously managing work and family caregiving roles. Guided by the stress process model, we investigate whether 823 employees occupying diverse family caregiving roles (child caregiving only, elder caregiving only, and both child caregiving and elder caregiving, or “sandwiched” caregiving...

Purpose The present study examined the moderating effects of family-supportive supervisor behaviors (FSSB) on the relationship between two types of workplace aggression (i.e., patient-initiated physical aggression and coworker-initiated psychological aggression) and employee well-being and work outcomes. Methodology Data were obtained from a field...

Study of the intersection of work with nonwork components of individuals’ lives has most often focused on roles within nuclear and extended families but is increasingly focused on nonwork domains beyond family, such as roles within friendships, communities, leisure activities, and the self. In line with the focus of most existing literature on the...

Drawing upon the Work-Home Resources model (ten Brummelhuis & Bakker, 2012), this study examined the links between work-family conflict and employed mothers’ profiles of time resources for work and parenting roles. Using a person-centered latent profile approach, we identified three profiles of time use and perceived time adequacy in a sample of mo...

This paper builds on a recent meta-analytic review on the relationships between organizational justice and health. Specifically, we examine the moderating role of perceived organizational support (POS) on the relationships between organizational justice and three objective cardiovascular health measures, namely, heart rate, systolic blood pressure,...

Although work schedulers serve an organizational role influencing decisions about balancing conflicting stakeholder interests over schedules and staffing, scheduling has primarily been described as an objective activity or individual job characteristic. The authors use the lens of job crafting to examine how schedulers in 26 health care facilities...

We draw on panel data from a randomized field experiment to assess the effects of a flexibility/supervisor support initiative called STAR on turnover intentions and voluntary turnover among professional technical workers in a large firm. An unanticipated exogenous shock-the announcement of an impending merger-occurred in the middle of data collecti...

Study objectives: Work-family conflict is a threat to healthy sleep behaviors among employees. This study aimed to examine how Work-to-Family Conflict (demands from work that interfere with one's family/ personal life; WTFC) and Family-to-Work Conflict (demands from family/ personal life that interfere with work; FTWC) are associated with several...

Objectives: To evaluate the effectiveness of the Safety and Health Involvement For Truckers (SHIFT) intervention with a randomized controlled design. Methods: The multicomponent intervention was a weight-loss competition supported with body weight and behavioral self-monitoring, computer-based training, and motivational interviewing.

Background Observational studies have linked work–family issues with cigarette consumption. This study examined the 6-month effects on cigarette consumption of a work–family supportive organisational intervention among nursing home workers. Methods Group randomised controlled trial where 30 nursing homes across New England states were randomly assi...

This study examined how polychronicity, or the preference to do several things concurrently, was related to work and family overload, work–family conflict, and outcomes in the work, family, and life domains (i.e. turnover intent, family, and life satisfaction). Using conservation of resources theory as a framework, polychronicity was conceptualized...

http://jag.sagepub.com/content/early/2016/03/31/0733464816641391?papetoc Based on the stress process model of family caregiving, this study examined subjective stress appraisals and perceived schedule control among men employed in the long-term care industry (workplace-only caregivers) who concurrently occupied unpaid family caregiving roles for c...

Job autonomy is a critical job characteristic in the construction industry, with lower levels of autonomy compared to the general working population. Moreover, there is a paucity of work on individual difference moderators, such as age, considering the effect of job autonomy in important outcomes, such as job satisfaction and mental health. The pur...

Objective: The objectives of the study were to describe a sample of truck drivers, identify clusters of drivers with similar patterns in behaviors affecting energy balance (sleep, diet, and exercise), and test for cluster differences in health safety, and psychosocial factors. Methods: Participants' (n = 452, body mass index M = 37.2, 86.4% male...

Objectives: Qualitative studies have highlighted the possibility of job loss following occupational injuries for some workers, but prospective investigations are scant. We used a sample of nursing home workers from the Work, Family and Health Network to prospectively investigate association between occupational injuries and job loss. Methods: We...

Objectives. Women who combine formal and informal caregiving roles represent a unique, understudied population. In the literature, healthcare employees who simultaneously provide unpaid elder care at home have been referred to as double-duty caregivers. The present study broadens this perspective by examining the psychosocial implications of double...

Training supervisors to increase their family-supportive supervisor behaviors (FSSB) has demonstrated significant benefits for employee physical health, job satisfaction, and turnover intentions among employees with high levels of family-to-work conflict in prior research in a grocery store context. We replicate and extend these results in a health...

The goal of this study was to test the effectiveness of a workplace intervention targeting work-life stress and safety-related psychosocial risk factors on health and safety outcomes. Data were collected over time using a randomized control trial design with 264 construction workers employed in an urban municipal department. The intervention involv...

We tested the effects of a work-family intervention on employee reports of safety compliance and organizational citizenship behaviors in 30 health care facilities using a group-randomized trial. Based on conservation of resources theory and the work-home resources model, we hypothesized that implementing a work-family intervention aimed at increasi...

This study examined feelings of having enough time (i.e., perceived time adequacy) in a sample of employed parents (N = 880) in information technology and extended-care industries. Adapting a person-centered latent profile approach, we identified 3 profiles of perceived time adequacy for paid work, parenting, and partner roles: family time protecte...

We investigated associations of work-family conflict and work and family conditions with objectively measured cardiometabolic risk and sleep. Multilevel analyses assessed cross-sectional associations between employee and job characteristics and health in analyses of 1,524 employees in 30 extended-care facilities in a single company. We examined wor...

Objectives: In the context of a group randomized field trial, we evaluated whether parents who participated in a workplace intervention, designed to increase supervisor support for personal and family life and schedule control, reported significantly more daily time with their children at the 12-month follow-up compared with parents assigned to th...

PurposeMost research on the work conditions and family responsibilities associated with work-family conflict and other measures of mental health uses the individual employee as the unit of analysis. We argue that work conditions are both individual psychosocial assessments and objective characteristics of the proximal work environment, necessitatin...

The workforce in most industrialized countries is aging and becoming more age-diverse, and this trend is expected to continue throughout the twenty-first century. Although there has been an increased interest in research on age differences at work, few studies have examined actual interventions designed to support workers at different points across...

This chapter reviews the literature on work–family interventions focusing on linkages to evidence-based employee health and well-being outcomes and on return on investment (ROI) in organizations. Work–family interventions include, but are not limited to, alternative work arrangements, family supportive supervisor behavior training, work redesign to...

Most existing research theorizes individual factors as predictors of perceived job insecurity. Incorporating contextual and organizational factors at an information technology organization where a merger was announced during data collection, we draw on status expectations and crossover theories to investigate whether managers' characteristics and i...
