OBJECTIVE: The primary objectives of this study were to identify sources of meaning for individuals within the context of a work environment, and to compare varied sources of meaning for individuals with high and low work satisfaction levels. METHOD: Participants were chosen based on satisfaction levels in employment, full-time employment status within an organization for at least one year, and diversity in the work setting. Data were gathered through a series of interviews and observations of the participants' workplaces. A comparative analysis of transcribed interviews was conducted by the researchers and with an expert occupational therapy faculty panel. From these analyses, the researchers developed work narratives for a mechanical engineer, a high school teacher, an employee of mechanical services, and a career service counselor. RESULTS: Emerging themes from the work narratives indicated that the various meanings employees found in work had an effect on their perceived levels of job satisfaction. Participants conveyed that organization identification, financial benefits, independent decision-making, reciprocal respect, opportunities for creativity, and maintaining significant relationships outside of work enhanced meaning and satisfaction. CONCLUSIONS: The worker role is a significant source of an individual's identity, meaning, and satisfaction in life. Professionals in various fields can work with employers to develop meaningful work environments for increased job satisfaction, greater motivation for work, increased productivity, and decreased employee turnover.  相似文献

This paper examines the impact of three types of victimization in childhood--sexual abuse, physical abuse, and neglect--on lifetime measures of mental health among adults. In contrast to research that relies on retrospective recall of childhood victimization, this work uses a prospective sample gathered from records of documented court cases of childhood abuse and neglect in a midwestern city around 1970. These subjects were interviewed about twenty years later. In addition, this research compares outcomes of the 641 members of the abuse and neglect group with a matched control group of 510 persons who did not have documented cases of abuse or neglect. The results indicate that men who were abused and neglected as children have more dysthymia and antisocial personality disorder as adults than matched controls, but they did not have more alcohol problems. Abused and neglected women report more symptoms of dysthymia, antisocial personality disorder, and alcohol problems than controls. After controlling for stressful life events, however, childhood victimization had little direct impact on any lifetime mental health outcome. This research indicates the importance of adopting an approach that places childhood victimization in the context of other life stressors and of prospective changes over the life course.  相似文献

This article describes the development, implementation, and replication of a group-based parenting program for families affected by substance abuse. The Nurturing Program for Families in Substance Abuse Treatment and Recovery improves parenting, as measured on objective scales; enhances parents' satisfaction and competence, as measured by participant reports; and is based on principles demonstrated to be effective in reducing risk of both child abuse and neglect and substance abuse for both parents and children.  相似文献

This Issue Brief examines the 1999 contribution behavior of 1.7 million 401(k) plan participants drawn from the EBRI/ICI Participant-Directed Retirement Plan Data Collection Project. The findings in this paper build on previous academic research examining the contribution activity of 401(k) participants, by using a large sample of participants in a wide range of plan sizes and by examining in detail the factors that influence contribution activity. Eighty-five percent of participants in the sample only made before-tax contributions to their plans, and 97 percent of all dollars contributed by employees were contributed on a before-tax basis. On average, participants contributed 6.8 percent of their salaries on a before-tax basis. Before-tax contribution activity varied among participants. About 61 percent of participants contributed more than 5 percent of their salaries on a before-tax basis and about 21 percent set aside more than 10 percent of their salaries on a before-tax basis. Eleven percent of participants analyzed in this study earning more than $40,000 a year contributed at the $10,000 before-tax IRC limit in 1999. Thirteen percent of participants with salaries between $70,000 and $80,000 contributed at the cap, and 18 percent of those with salaries between $80,000 and $90,000 were at the limit. However, it appears that among participants not contributing at the IRC limit, 52 percent could not have done so because of formal plan-imposed contribution limits below the IRC limit. Older participants tended to contribute a higher percentage of their salaries to plans than did younger participants, even after factoring out differences in salary and job tenure. Participants tended to increase the share of their salary (and amounts) contributed to their 401(k) plan as their salaries rose until salaries reached $80,000. For individuals with salaries above $80,000, before-tax contribution rates (though not the amounts contributed) tended to fall as salaries rose because IRC, and possibly plan sponsor, contribution limits became binding for some participants. Giving employees the option of borrowing from their 401(k) accounts increased participant contribution rates. On average, a participant in a plan offering loans appeared to contribute 0.6 percentage point more of his or her salary to the plan than a participant in a plan with no loan provision. Total contributions--the sum of employee and employer contributions--were higher for participants who received an employer contribution as part of their 401(k) plan than for those who did not. The average total contribution rate was 10 percent of salary for employees in plans offering an employer contribution, compared with 7.4 percent for those in plans not offering an employer contribution.  相似文献

This prospective study examines the epidemiology of physical attack and rape among a sample of 171 not-in-treatment, crack-cocaine using women. Since initiating crack use, 62% of the women reported suffering a physical attack. The annual rate of victimization by physical attack was 45%. Overall, more than half of the victims sought medical care subsequent to an attack. The prevalence of rape since crack use was initiated was 32%, and the annual rate was 11%. Among those women having been raped since they initiated crack use, 83% reported they were high on crack when the crime occurred as were an estimated 57% of the perpetrators. Logistic regression analyses showed that duration of crack use, arrest for prostitution, and some college education were predictors of having experienced a physical attack. Duration of crack use and a history of prostitution were predictors of suffering a rape. Drug abuse treatment programs must be sensitive to high levels of violence victimization experienced by crack-cocaine using women. Screening women for victimization, and treating the problems that emanate from it, may help make drug abuse treatment more effective.  相似文献

High-stress individuals may benefit from social support, although their support providers may be adversely affected via stress crossover effects. Individual and crossover effects of perceived stress within medical student marriages (n = 30) were investigated. Perceived spousal support was positively associated with individuals' own marital and emotional adjustment, attenuating stress effects. With regard to crossover effects, medical students' perceived stress was significantly associated with their spouses' emotional adjustment. Further, medical students' own emotional adjustment fully mediated this crossover effect. Results suggest that the contagion of negative affect may serve as a key mechanism through which stress crossover effects operate in marriage.  相似文献

OBJECTIVES: Identify associations between lack of formal boater training, drinking and boating, and other unsafe boating practices. METHODS: A telephone survey queried respondents (age 16 or older in continental United States) about boating experience, type of boat used, and training. RESULTS: Of the 3,042 boaters surveyed (70% response), most had no formal training (73%). Boaters with formal training failed to use PFDs about as often as those without formal training and were equally or more likely to use alcohol while boating. CONCLUSIONS: The unexpected association between formal training and unsafe boating practices is probably due to reduced risk perception and inadequacies of boater training programs. Such programs seldom mention the risks of alcohol use while boating. Decisions to mandate formal training should be informed by these results; if mandated, training should address the risks of alcohol use while boating, and should be renewed frequently enough to offset reductions in risk perception.  相似文献

1. Videotaping is a beneficial instructional methodology to help undergraduate students develop awareness of their strengths and opportunities for growth in therapeutic interactional skills. 2. Educational interventions with undergraduate students provide an opportunity to involve doctoral students in vital instruction, research, and knowledge dissemination through publication and presentation. 3. Allowing novice nurses to view their interactional skills with a simulated patient can reduce the anxiety they experience in first therapeutic encounters with assigned patients. 4. Continuous quality improvement in educational methodology is dependent on listening carefully to students who have invaluable feedback to offer and making appropriate correction as indicated.  相似文献
