Organizational response to recommendations based on a study of stress among correctional officers

A study was recently commissioned by the South Australian Government to study the nature and sources of stress among correctional (prison) officers. The paper reports on the key variables found to have significant predictive effects on strain (a composite measure comprising psychological distress, physical ill-health symptoms, job dissatisfaction, and work-home conflict). These included demographic variables (length of service, finances), personal variables (negative affectivity), work environment variables (work role ambiguity, institutional relationship concerns, inmate concerns, worktime concerns, low autonomy, and low involvement), and emotional suppression. Recommendations were formulated including: the appointment of a full-time mental health counselor, organizational and individual strategies aimed to improve supervisor support and management training, greater participation in organizational decision making, and post-shift debriefing. It was also suggested that in selecting correctional officers those displaying high levels of negative affectivity should be screened out. Finally, it was recommended that intervention should target the most vulnerable individuals, including shiftworkers, officers who had been employed in the organization the longest, officers currently on stress leave and officers, who have previously been on stress leave and have returned to work. The paper reports on the organizational response to the recommendations and the implications of the study are discussed in the context of ongoing surveillance and evaluation of the impact of intervention strategies.     

Effects of d-amphetamine and cocaine on strained ratio behavior in a repeated-acquisition task.

Pigeons acquired a different four-response chain each session by responding sequentially on three keys in the presence of four colors. When the fixed-ratio requirement for food presentation was five completions of the chain, d-amphetamine and cocaine disrupted the behavior. As the dose of each drug was increased, the overall response rate decreased, the overall accuracy was impaired (i,e., percent errors increased), and there was less within-session error reduction (acquisition). In contrast, when the fixed-ratio requirement was either 20 or 50 completions of the chain, certain doses of both drugs produced large increases in the overall response rate by eliminating the extended pausing (ratio strain) that was characteristic of the control sessions. These rate-increasing effects were accompanied by error-decreasing effects, both during acquisition and after the response chain had been acquired. Taken together, the results show that the effects of d-amphetamine and cocaine on behavior in a repeated-acquisition task can be modulated by manipulating the value of the fixed-ratio schedule maintaining the behavior.     

家庭经济压力与青少年抑郁:歧视知觉和亲子依恋的作用

对703名初中生(平均年龄14.30岁)进行问卷调查, 探讨了青少年歧视知觉、亲子依恋在家庭经济压力与青少年抑郁关系中的中介和调节作用。结果表明:(1)在控制了性别、年级后, 家庭经济压力对青少年抑郁具有显著的正向预测作用;(2)在家庭经济压力对抑郁的正向预测关系中, 歧视知觉起中介作用;(3)家庭经济压力通过歧视知觉对抑郁的中介作用受到亲子依恋的调节, 相对于亲子依恋水平较高的青少年, 中介效应仅在亲子依恋水平较低的青少年中显著。     

Work, family and life-course fit: Does control over work time matter?

This study moves from “work-family” to a multi-dimensional “life-course fit” construct (employees’ cognitive assessments of resources, resource deficits, and resource demands), using a combined work-family, demands-control and ecology of the life course framing. It examined (1) impacts of job and home ecological systems on fit dimensions, and (2) whether control over work time predicted and mediated life-course fit outcomes. Using cluster analysis of survey data on a sample of 917 white-collar employees from Best Buy headquarters, we identified four job ecologies (corresponding to the job demands-job control model) and five home ecologies (theorizing an analogous home demands-home control model). Job and home ecologies predicted fit dimensions in an additive, not interactive, fashion. Employees’ work-time control predicted every life-course fit dimension and partially mediated effects of job ecologies, organizational tenure, and job category.     

上下级沟通对工作应激源-应激的调节作用研究

本研究旨在考察上下级沟通对工作应激源-心理及生理应激的调节作用。研究结果表明:上下级沟通的两个维度及时告知和指导、积极表达对应激源-应激有不稳定的、不强烈的调节作用,既表现为及时告知与指导对工作-家庭冲突与心理应激、对工作负荷-生理应激有缓冲作用(负向作用),也表现为积极表达对工作-家庭冲突-生理应激、及时告知和指导对攻击行为-心理应激有增强作用(正向作用)。     

Infanticide and maternal aggression: Synchrony of male and female reproductive strategies in mice

Thirty-six percent of male mice from three strains attacked newborn pups sired by another male. No male attacked its own offspring. Females did not show differential aggression toward males likely (strangers) or unlikely (sires) to attack their pups. Both forms of aggression were unaffected by housing in rooms which did or did not contain the aggression targets. The three strains differed in strength of maternal aggression but not in the incidence of infanticide. Females showed more aggression when mated with males of the same, rather than a different, strain but no differences with intruders of the same or a different strain. Infanticide by males is best viewed as a postcopulatory, intermale-competition strategy, and maternal aggression as a counter strategy.     

A matter of style? Testing the moderating effect of driving styles on the relationship between job strain and work-related crashes of professional drivers

Different empirical studies suggest that both job strain and driving styles are significant contributors to the work-related traffic crashes suffered by professional drivers. Nevertheless, the current evidence falls considerably short when explaining why driving styles may modify (or not) the relationship between occupational stressors and professional drivers’ safety outcomes. The aim of this study was to examine whether driving styles moderate the effect of job strain on professional drivers’ Work Traffic Crashes (WTCs). This research was performed using the data collected from a sample of 753 professional drivers, responding to a self-report questionnaire on job strain (work stress indicator of the Job Demand-Control model), driving styles and work-traffic safety outcomes suffered in the past two years. Regression-based moderation analyses suggest that the job strain of professional drivers is positively associated with the occupational traffic crashes they suffer, and that such association is stronger in drivers with “reckless & careless”, “anxious”, and “angry & hostile” driving styles. Meanwhile, the “patient & careful” (positive) driving style was not associated with a lower risk of suffering a WTC, nor with a lower vulnerability to stress-related WTCs. The results of this study support the hypothesis that driving styles exert a statistical moderation between the job strain and the occupational traffic crashes suffered by professional drivers. These findings may support the design of evidence-based interventions in both the organizational and individual levels, focused stress-related factors and driving styles as predictors of work traffic crashes.     

教育价值观和逆境信念在家庭经济压力与初中生学业成就之间的作用

大量研究表明,家庭经济压力对青少年学业成就具有显著的不利影响。但是,目前学界对家庭经济压力“怎样”（中介机制）以及“何时”（调节机制）影响青少年学业成就仍知之甚少。本研究在整合贫困文化模型及心理韧性理论的基础上构建一个有调节的中介模型,考察青少年教育价值观（读书是否有用）在家庭经济压力与学业成就之间的中介作用,同时检验中国文化逆境信念对该中介路径的调节作用。采用随机整群抽样,选取四川省9所普通中学1613名初中生（平均年龄13.42岁,SD = 1.22）作为研究对象。被试匿名填写家庭经济压力问卷、教育价值观问卷、中国文化逆境信念量表以及学业成就问卷。结果表明：（1）在控制了性别、年龄等人口学变量后,家庭经济压力显著负向预测学业成就。（2）教育价值观在家庭经济压力与学业成就之间具有部分中介作用。（3）积极逆境信念能缓冲家庭经济压力对教育价值观的消极作用,进而减少对学业成就的不利影响。本研究证实了“读书无用论”是经济困难与学业成就的重要联系机制,并肯定了中国文化逆境信念对经济困难青少年的保护作用。这一内在保护机制的揭示对教育实践有一定的启示。     

Relations between stress and work outcomes: The role of felt challenge, job control, and psychological strain

Recent research on reported work stress indicates stress may not always be deleterious for an individual or organization. Research in this area, however, has not yet examined a variety of work outcomes, the mechanism by which stress leads to such outcomes, and the moderators of this effect. The present study hypothesized that two types of reported stress (challenge- and hindrance-related) have a divergent relationship with work outcomes (relating to desirable and undesirable outcomes, respectively) and a similar (positive) relationship with psychological strain. We also hypothesize felt challenge as a mechanism through which challenge stress relates to desirable outcomes and job control as a moderator of the effect. Results from a heterogeneous sample of university staff employees (N=461) supported many of the hypotheses. The two types of stress differentially related to work outcomes yet both positively related to psychological strain. In addition, felt challenge mediated the relationship between challenge-related stress and work outcomes, yet the effect of challenge-related stress did not depend on job control.
