TL;DR: Five different methods of integration are proposed: a qualitative approach as a foundation for the design of a quantitative study, qualitative studies to gain deeper insight and better analyses of the results from a qualitative study, quantitative research to study frequencies and distributions of phenomena discovered by qualitative approaches, parallel and integrated use of qualitative and quantitative approaches, and quantifying qualitative data.
Abstract: The old controversy between qualitative and quantitative approaches to the study of workplace stressors and workers ́ health may be bypassed by looking at them as complementary to each other. Especially, intervention research would profit from the integrated use of both approaches when it comes to validity and reliability of the data. This applies to assessment of both the work and health related problems as well as the effects of the intervention. Also quite practical issues must be considered, such as the question of status for the two approaches within the research group, the possibility to integrate the two methods, not only conduct them in separate and parallel processes, and the sequencing of the approaches. Five different methods of integration are proposed: 1) a qualitative approach as a foundation for the design of a quantitative study, 2) qualitative studies to gain deeper insight and better analyses of the results from a quantitative study, 3) quantitative research to study frequencies and distributions of phenomena discovered by qualitative approaches, 4) parallel and integrated use of qualitative and quantitative approaches, and 5) quantifying qualitative data.

TL;DR: The Practice Environment Scale–Nursing Work Index (PES–NWI) seems to be one of the most promising instruments because of its appropriateness, its structure, which has a rather good fit, and its ability to discriminate magnet hospitals like other NWI derivates (discriminant validity).
Abstract: This systematic review assesses the validity of epidemiological questionnaires used to measure psychosocial and organizational work factors (POWFs) in nurses Of the 632 articles published between 1980 and July 2008 identified in this review, 108 provide some data concerning analysis of the intrinsic characteristics of such instruments (content validity or conceptual basis, reliability, validation of internal construction) and their external validity with respect to health aspects (concurrent validity and predictive validity) Psychometric properties of generalist questionnaires validated among blue collar or white collar workers were also assessed in the nurse population The Job Content Questionnaire (JCQ), because of its longevity and reputation, was the generalist questionnaire most used among this population Although its structure often raises questions in the nurse population, its dimensions (mainly the control one) have been shown to be predictive of some health outcomes measured with "objective" indicators concerning absenteeism, injuries, and musculoskeletal disorders Effort Reward Imbalance (ERI), which has a structure more stable among the nurse population, has shown concurrent validity in terms of intent to leave the nursing profession No questionnaire specifically designed for nurses can claim to satisfy all of the recommendations in terms of internal validity Nevertheless, the Practice Environment Scale-Nursing Work Index (PES-NWI) seems to be one of the most promising instruments because of its appropriateness (content validity), its structure, which has a rather good fit (construct validity), its ability to discriminate magnet hospitals like other NWI derivates (discriminant validity), and it has also been associated in cross-sectional studies with health outcomes, especially nurses' self-assessed mental health but also with patients' health outcomes objectively assessed (concurrent validity) However, elements for predictive validity are still lacking with NWI derivates The Discussion provides recommendations for measuring POWFs, encompassing the use of external validated measurements

TL;DR: The (lack of) stability in units of analysis in occupational health and safety intervention projects directed toward worksites is described to raise serious questions concerning design, analyses and interpretation of results.
Abstract: Interventions in occupational health often target worksites rather than individuals. The objective of this paper is to describe the (lack of) stability in units of analysis in occupational health and safety intervention projects directed toward worksites. A case study approach is used to describe naturally occurring organizational changes in four, large, Nordic intervention projects that ran 3–5 years, covered 3–52 worksites, cost 0.25 mill–2.2 mill €, and involved 3–7 researchers. In all four cases, high rates of closing, merging, moving, downsizing or restructuring was observed, and in all four cases at least one company/worksite experienced two or more re-organizations during the project period. If individual worksites remained, ownership or (for publicly owned) administrative or legal base often shifted. Forthcoming closure led employees and managers to seek employment at other worksites participating in the studies. Key employees involved in the intervention process often changed. Major changes were the rule rather than the exception. Frequent fundamental changes at worksites need to be taken into account when planning intervention studies and raises serious questions concerning design, analyses and interpretation of results. The frequent changes may also have deleterious implications for the potential effectiveness of many real life interventions directed toward worksites. We urge researchers and editors to prioritize this subject in order to improve the quality of future intervention research and preventive action.

TL;DR: The results of the analyses with time lag (longitudinal) did not support the hypothesis that psychosocial and physical strain from 1 day of work predicts pain onset the following day, but physical exertion, stress, and, to some extent, time pressure were associated with pain on the day of onset.
Abstract: Objectives The aim of this study was to investigate psychosocial factors and physical exertion at work in relation to the onset of low-back pain.
Methods The study was carried out as a case-crossover investigation of nursing aides caring for the elderly. Cases were identified among 157 nursing aides over a period of 2 years. Psychosocial factors, physical exertion, and low-back pain were reported daily in diary questionnaires over three consecutive days at work, repeated in six periods of 3 days. For each subject, case observations were identified as pain onset from one day to the next and matched with reference observations with no pain onset from the same person. Prospective data collection allowed analyses to be conducted with and without a lag in time between exposure and pain onset.
Results The results of the analyses with time lag (longitudinal) did not support the hypothesis that psychosocial and physical strain from 1 day of work predicts pain onset the following day. However, physical exertion, stress, and, to some extent, time pressure were associated with pain on the day of onset.
Conclusion The effect period, if any, of exposure to physical exertion, stress, and time pressure on the onset of acute low-back pain is considered to be less than 24 hours.

TL;DR: The results showed that the experience of workload, ergonomic troubles, psychosocial troubles and work stress had decreased at the same time as theExperience of stimulation and of joy at work had increased.
Abstract: A work environment intervention to test a model of age related workload was carried out at a local hospital. The staff received training about life course, work and work ability. Efforts at making changes in the work place were encouraged. Action plans were to be presented and the participating wards were given a grant in relation to the existing age structure, to carry out changes and to recruit younger persons. The results showed that the experience of workload, ergonomic troubles, psychosocial troubles and work stress had decreased at the same time as the experience of stimulation and of joy at work had increased. It was not possible to see any reduction in the HR costs or change in the working time and sick leaves. The action plans showed limited suggestions of changes. The organization's complexity and the traditional hierarchy of hospitals do not stimulate change, but the supervisors' involvement is also critical to the result of the staff's work. Work environment interventions are complicated and complex and influenced by many factors. One year is a very short time for an intervention. The importance of the experience of the staff of an improved work environment is however not to be diminished.

TL;DR: It is argued that intervention studies are in great demand, and often there is a wish that etiologic questions as well as prevention effectiveness be addressed in the same study, but this should not be done without careful consideration of possible conflicting design aspects.
Abstract: In this article a basic distinction is made between etiologic and prevention effectiveness intervention studies. Etiologic intervention studies focus on elucidating causes of disease, while the purpose of prevention effectiveness intervention studies is to study methods of prevention. The design requirements for each of these studies are very different: etiologic intervention studies usually need large study populations, large exposure contrasts, ascertainment of exposure, as well as health outcome. Ideally, randomization and blinding should also be applied. Effective preventive strategies may, on the other hand, be identified in small study populations with exposure as the only outcome measure, and randomization and blinding may be superfluous. At present, intervention studies are in great demand, and often there is a wish that etiologic questions as well as prevention effectiveness be addressed in the same study. We argue that this should not be done without careful consideration of possible conflicting design aspects. © 1996 Wiley-Liss, Inc.

TL;DR: It appears feasible to create a check-list to assess ergonomic errors in a reliable way and to evaluate whether trained nurses work more safely in their daily duties than during the study.
Abstract: Objectives: The objectives of this study were (i) To establish whether it is possible to assess by means of a check-list in a reliable way errors which violated biomechanical and ergonomical principles during nursing tasks, and (ii) to study the effectiveness of an ergonomic-educational course by using this check-list. Materials and methods: Trainees (n=12) and a control group of nurses (n=12) who did not attend the course, performed three nursing activities at three points in time under standardized conditions; once before and twice after the course had ended. Their performances were recorded on video. A check-list was developed to assess the number of ergonomic errors made during the test performances. Two observers completed the check-lists after having watched five videotapes, and one of them did this for a second time 3 weeks later, in order to assess inter- and intra-observer reliability. In addition the tapes of all nurses were scored and analysed on differences in the performance of the two groups at the three points in time. Percentage of agreement and kappa (κ) was used to express inter- and intra-observer reliability. Student’s t-test was used to analyse the differences in mean percentages of errors. Results: The inter- and intra-observer reliability were 92% with κ of 0.84, and 93% with κ of 0.86, respectively. Further results showed that the mean percentages of errors made by the control group remained the same at the three measurement times. However, in the trainee group a significant decrease in errors was found. The trainees made fewer errors at all three points in time than the controls did. Conclusion: It appears feasible to create a check-list to assess ergonomic errors in a reliable way. Trainees make fewer errors after an ergonomic-educational course. It is necessary, however, to evaluate whether trained nurses work more safely in their daily duties than during the study.

TL;DR: Stress has been linked directly to almost every common disease, from heart disease to flu, and is thus a major contributor to personal health.
Abstract: One of the consequences of the industrial era has been the rise of stress as a health and social problem. Stress seems to grow as a byproduct of the pressures, changes and demands of modern life and work. It is a problem that every person experiences, yet it seems so pervasive and global that many people do not believe they can do much to overcome its negative effects. Stress has been linked directly to almost every common disease, from heart disease to flu. Stress is thus a major contributor to personal health.
