Objective Investigate new bus operators’ ( n = 293) occupational and health backgrounds to inform how transit authorities can support their future health and job success. Methods New bus operators completed surveys and direct measurements that addressed demographics, work history, and 10 health risk factors. Results Participants averaged 42.76 ye...

The effective socialization of newcomers into organizations is critical for employee and organizational success. As such, ensuring successful onboarding has become even more pivotal for newcomer adjustment, performance, and retention. The literature has seen significant growth and incorporated new theoretical perspectives, such as resource-based ap...

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...

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...

Background Truck driving is a highly sedentary occupation that places workers at risk for chronic health conditions, such as obesity and high blood pressure. The primary purpose of this study was to objectively describe truck drivers' typical physical activity (PA) patterns. Methods We used ∼7–10-day baseline PA actigraphy data samples from driver...

Introduction Ambulatory blood pressure monitoring (ABPM) across 24 hours is recommended to confirm hypertension and, outside of a laboratory setting, is the only means to measure the extent of any nocturnal decrease in blood pressure (BP) i.e., nocturnal BP dipping. The ambulatory device is traditionally programmed to inflate every 20-30 minutes du...

Objective: To test the feasibility and efficacy of an enhanced onboarding intervention to prevent weight gain and support the early job success of new bus operators. Methods: Control participants (n = 9) completed usual practice new employee training and onboarding. Intervention participants (n = 14) completed five supplemental trainings and fou...

Given the rapid growth of intervention research in the occupational health sciences and related fields (e.g. work-family), we propose that occupational health scientists adopt an "alpha, beta, gamma" change approach when evaluating intervention efficacy. Interventions can affect absolute change in constructs directly (alpha change), changes in the...

Background: Individuals with mild traumatic brain injury (mTBI) may experience chronic cognitive-linguistic impairments that are difficult to evaluate with existing measures. Garden path sentences are linguistically complex sentences that lead readers down a path to an incorrect interpretation. Previous research indicates many individuals, with or...

Risk for adverse cardiovascular events increases when blood pressure does not decrease at night ("non-dipping", <10% decrease from daytime blood pressure). Shiftwork alters relationships between behaviors and endogenous circadian rhythms (i.e., circadian disruption along with variable sleep timing), and chronic shiftwork increases cardiovascular di...

Objective: To empirically assess retrospective reports of weight changes during bus operators' first years on the job, and to investigate experienced and desired training topics for new operators. Methods: Bus operators (n = 261) completed an online survey on topics of early weight changes and training experiences. Results: Operators reported...

Purpose Despite the proliferation of work–family research, a thorough understanding of family role status changes (e.g. the gaining of elder or child caregiving responsibilities) remain under-theorized and under-examined. The purpose of this paper is to conceptualize various forms of family role status changes and examine the ways in which these ch...

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...

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...

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 aging of the industrialized workforce has spurred research on how to support people working later in life. Within this context, the concept of work ability, or an employee’s ability to continue working in their job, has been introduced as an explanatory mechanism for understanding employee disability, wellbeing, attitudes, and behavior. However...

Conventional opinion about using Rapid Serial Visual Presentation (RSVP) for examining sentence comprehension maintains that RSVP taxes working memory (WM), which probably affects sentence processing. However, most RSVP studies only infer the involvement of WM. Other cognitive resources, such as cognitive control or vocabulary may also impact sente...

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...

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,...

Objectives/Hypothesis Minimum clinically important differences (MCIDs) for the 22‐item SinoNasal Outcomes Test (SNOT‐22) in patients with chronic rhinosinusitis (CRS) electing endoscopic sinus surgery (ESS) are well described. However, similar estimations for the MCID have not been investigated for patients electing continued appropriate medical th...

Background: In a cluster-randomized trial, the Safety and Health Involvement For Truck drivers intervention produced statistically significant and medically meaningful weight loss at 6 months (-3.31 kg between-group difference). The current manuscript evaluates the relative impact of intervention components on study outcomes among participants in...

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...

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...

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...

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...

Researchers working in the context of randomized trials routinely estimate and test for treatment effects on the study outcomes. This article discusses the merits of assessing differential treatment effects across outcomes and proposes a multivariate approach using standardized outcomes for this purpose. This multivariate approach extends prior app...

Background: Prior work has described 5 domains within the 22-item Sino-Nasal Outcomes Test (SNOT-22) that allow for stratification of symptoms into similar clusters and that can be used to direct therapy. Although the outcomes of various interventions on these symptom domains have been reported, minimal clinically important difference (MCID) value...

Calls continue for randomized interventions in organizational settings. In many cases, however, practical constraints require researchers to use 2-wave randomized pretest-posttest control group designs. We discuss the importance of randomized trials for theory development with a focus on analytic options for 2-wave designs. Our discussion has impli...

Background: Olfactory dysfunction is a common and defining symptom of chronic rhinosinusitis (CRS). Many measures of olfactory dysfunction in CRS are limited by scoring criteria defined within general populations with interpretations of statistical significance to infer clinically meaningful improvement. In this investigation we define a minimal c...

Wilkinson and Task Force on Statistical Inference (1999) recommended that researchers include information on the practical magnitude of effects (e.g., using standardized effect sizes) to distinguish between the statistical and practical significance of research results. To date, however, researchers have not widely incorporated this recommendation...

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,...

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. We evaluate...

This article revisits how the end points of plotted line segments should be selected when graphing interactions involving a continuous target predictor variable. Under the standard approach, end points are chosen at ±1 or 2 standard deviations from the target predictor mean. However, when the target predictor and moderator are correlated or the con...

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...

Background: Diagnostic nasal endoscopy is a routine measure of sinonasal inflammation in patients with chronic rhinosinusitis (CRS). Although multiple staging systems have been proposed and evaluated, evidence of association between concurrent symptoms and endoscopic findings remains discordant. The goal of this study is to identify the relevant e...

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...

Drawing on the structural perspective in organizational theory, this study develops a conceptual framework of the social hierarchy within the multinational corporation (MNC). We suggest that parent country nationals (PCNs), host country nationals (HCNs), and third country nationals (TCNs) occupy distinctively different positions in the social hiera...

Study objectives: The Work, Family, and Health Network Study tested the hypothesis that a workplace intervention designed to increase family-supportive supervision and employee control over work time improves actigraphic measures of sleep quantity and quality. Design: Cluster-randomized trial. Setting: A global information technology firm. Pa...

Total Worker Health (TWH) was introduced and the term was trademarked in 2011 by the National Institute for Occupational Safety and Health (NIOSH) to formally signal the expansion of traditional occupational safety and health (OSH) to include wellness and well-being. We searched PubMed, PsycInfo, and other databases using keywords TWH, health promo...

Background Prior study demonstrated that baseline 22-item Sino-Nasal Outcome Test (SNOT-22) aggregate scores accurately predict selection of surgical intervention in patients with chronic rhinosinusitis (CRS). Factor analysis of the SNOT-22 survey has identified 5 distinct domains that are differentially impacted by endoscopic sinus surgery (ESS)....

Objective: To provide a baseline description of psychosocial workplace stressors and supports along with safety, injury, health, and well-being indicators in a sample of utility and construction workers for a National Institute for Occupational Safety and Health-funded Total Worker Health™ intervention study. Methods: Survey responses and health...

Importance Patient-reported measures are designed to detect a true change in outcome, but they are also subject to change from biases inherent to self-reporting: changing internal standards, changing priorities, and changing interpretations of a given instrument. These biases are collectively known as “response shifts” and can obscure true change...

Although critical to health and well-being, relatively little research has been conducted in the organizational literature on linkages between the work-family interface and sleep. Drawing on conservation of resources theory, we use a sample of 623 information technology workers to examine the relationships between work-family conflict, family-suppo...

Past research has examined reactions to traditional, gender- and ethnicity-based affirmative action programs. However, research has not examined reactions to affirmative action based on socioeconomic status (SES), even though such programs are promoted by the U.S. government (e.g., Work Opportunity Tax Credit) and thus act as a de facto supplement...

Recently, scholars have demonstrated the importance of Family Supportive Supervisor Behaviors (FSSB), defined as behaviors exhibited by supervisors that are supportive of employees' family roles, in relation to health, well-being, and organizational outcomes. FSSB was originally conceptualized as a multidimensional, superordinate construct with fou...

Confirmatory tetrad analysis is based on tetrads that are assumed to be 0 or to "vanish" under an assumed model to test the goodness of fit of a model or the relative fit of nested models. A strength of a tetrad-based approach to model fit assessment over standard methods is that researchers can evaluate the plausibility of a theoretical model stru...

The unique demands of truck driving result in elevated levels of occupational fatalities, injuries, and lifestyle-related illnesses. Rates of overweight and obesity are higher than the general population (Centers for Disease Control, 2006b; Kashima, 2003; Korelitz et al., 1993). Obesity has established mortality and disease consequences, including...

This article outlines the development of a 14-item measure of socio-cognitive mindfulness. Using 9 samples (including multisource and multi-wave data) with a total of 4,345 responses the authors developed a reliable scale with a tri-dimensional factor structure that replicated across 5 separate samples. The scale possessed both convergent and discr...

Chronic low level exposure of agricultural workers and applicators to pesticides has been found to be associated with different degrees of decrement in cognitive and psychomotor functions. The goal of this study was to use meta-analysis to (1) identify and quantify neurobehavioral deficits among agricultural workers and pesticide applicators, and (...

This article uses meta-analysis to develop a model integrating research on relationships between employee perceptions of general and work-family-specific supervisor and organizational support and work-family conflict. Drawing on 115 samples from 85 studies comprising 72,507 employees, we compared the relative influence of 4 types of workplace socia...

Drawing on a conceptual model integrating research on training, work–family interventions, and social support, we conducted a quasi-experimental field study to assess the impact of a supervisor training and self-monitoring intervention designed to increase supervisors' use of family-supportive supervisor behaviors. Pre- and postintervention surveys...

One cost effective way to improve applicant reactions is by giving explanations. Although a literature on this topic has accumulated, the effects of explanations on applicant reactions have not been examined meta-analytically, and several aspects of giving explanations to applicants are unclear. For example, do explanations affect applicant reactio...

The article focuses on a meta-analytical framework that is based on a life course perspective for predicting retirement decisions. The individual characteristics of the employee such as gender and health, the employment-related factors such as salary and job satisfaction, the effect of the employee's attitude about retirement, the variables related...

Due to growing work-family demands, supervisors need to effectively exhibit family supportive supervisor behaviors (FSSB). Drawing on social support theory and using data from two samples of lower wage workers, the authors develop and validate a measure of FSSB, defined as behaviors exhibited by supervisors that are supportive of families. FSSB is...

In the three decades after the publication of the first meta-analyses in the behavioral sciences, hundreds of articles and a number of technical guides have emerged concerning meta-analytic practice and reporting standards. The purpose of the present study is to review the practice and reporting standards of a random sample of published meta-analys...

The purpose of this archival research was to investigate whether coping moderated the association between disability status and the outcome of psychosocial adaptation while controlling for demographic variables, posttraumatic stress disorder, and environmental conditions and social support. This research analyzed data from the U.S.'s National Vietn...

When using multiple imputation in the analysis of incomplete data, a prominent guideline suggests that more than 10 imputed data values are seldom needed. This article calls into question the optimism of this guideline and illustrates that important quantities (e.g., p values, confidence interval half-widths, and estimated fractions of missing info...

An important limitation of conventional latent-growth modeling (LGM) is that it assumes that all individuals are drawn from one or more observed populations. However, in many applied-research situations, unobserved subpopulations may exist, and their different latent trajectories may be the focus of research to test theory or to resolve inconsisten...

The authors tested a model of antecedents and outcomes of newcomer adjustment using 70 unique samples of newcomers with meta-analytic and path modeling techniques. Specifically, they proposed and tested a model in which adjustment (role clarity, self-efficacy, and social acceptance) mediated the effects of organizational socialization tactics and i...

Many factors affect the growth and development of children, including chemicals in the environment. Children have greater exposure to toxicants than adults due to both behavior and their increased food: body-mass ratio. Furthermore, the developing brain and organ systems of infants and children and their immature metabolism also make them more vuln...

Tetrad tests are a valuable tool for testing covariance structures, particularly when other tests such as the likelihood ratio test are not appropriate. However the implementation of tetrad tests is complicated by the fact that there are often multiple sets of nonredundant vanishing tetrads, and also by computational limitations, particularly for b...

Results are described for a survey assessing prevalence of missing data and reporting practices in studies with missing data in a random sample of empirical research journal articles from the PsychINFO database for the year 1999, two years prior to the publication of a special section on missing data in Psychological Methods.
