Research paper thumbnail of Idea Adoption in Workplace Innovation: Scale Development and Initial Validity Evidence

The purpose of this study was to develop and validate a scale that measures the process of idea adoption. More specific, the scale assesses the behavior of supervisory leaders in terms of idea openness, selection and application. Three studies were conducted to develop the idea adoption scale and investigate its psychometric properties (Study 1, n = 326); establish concurrent, convergent and divergent validity (Study 2, n = 334); and assess test-retest reliability over a three month period (Study 3, n = 189). The findings showed that the full idea adoption scale and its subscales have good psychometric properties: the three factor structure was supported and scales showed internal consistency and retest reliability. Furthermore, the scales’ associations with other variables provided initial evidence for concurrent, convergent and divergent validity. Several recommendations are made for the application of the scale in research and practice.

We used several theoretical frameworks to select our research variables. In line with the contingency and sociotechnical system approaches, we selected complexity, uncertainty, and decision authority to represent the organizational characteristics. As to the work characteristics, we selected

The second aim was to validate whether a specific pattern of relationships between work characteristics and reactions was the same for mental health and general nurses. Nurses are generally being considered as an above risk group regarding work stress. However, health care is a diverse sector and literature suggests important differences regarding the work of different categories of nursing, such as general and mental health nurses. In addition, little empirical evidence exists about these differences. In order to improve their work situation, more insight is needed regarding differences and similarities in the work of general and mental health nurses. The demand-control-support (DCS) model was used as a research framework. We hypothesized that autonomy, job involvement, and emotional exhaustion are higher in mental health nursing, whereas social support is expected to be lower. Next, in line with the propositions of this model and several recent studies, we hypothesized that emotional exhaustion is primarily predicted by workload and social support, whereas job involvement is primarily predicted by autonomy. In addition, we investigated whether this pattern of relationships was similar in both groups. Questionnaires were distributed to nurses working in a general and a psychiatric hospital in the Netherlands. We used MANOVA and MSA (by means of LISREL) to analyse the data. Regarding the differences in work characteristics and work reactions between mental health and general nurses, our hypotheses were confirmed, except for social support and job involvement. Autonomy and emotional exhaustion were higher among mental health nurses, whereas their job involvement proved to be significantly lower. Emotional exhaustion was primarily predicted by workload and lack of social support. Contrary to our expectations, the relationship between autonomy and job involvement was not significant in both samples. Finally, we found that the proposed pattern of relationships appeared to be invariant across the two samples.

Background: In traditional health care settings, nurses exhibit a high level of environmental uncertainty and low decisionmaking authority, which has a negative effect on psychological reactions towards work. In professional nursing, specialisation, e.g. diabetic nursing, is a current trend in many countries. Therefore, insight into the determinants of the work situation of nursing specialists is becoming increasingly relevant. Methods: Comparisons were made between 3 different samples: 1204 nurses employed by 15 hospitals, 1058 nurses employed by 14 nursing homes, and 350 diabetes nurses working in other health care settings throughout the Netherlands. Data concerning organisation, work aspects, and psychological reactions were measured via questionnaires. Variances between the groups were analysed with ANCOVA, besides hierarchical multiple regression analysis was applied. Findings: Environmental uncertainty scored lower amongst diabetes nurses when compared to nurses working in the other two types of health care settings. Social support and role conflict scored low for diabetes nursing specialists who simultaneously perceived autonomy and role ambiguity highest. Diabetes nursing specialists also scored highest on intrinsic work motivation and job satisfaction and lowest for psychosomatic health. Conclusion: Except for social support and role ambiguity, diabetic nurses rate their [work] organisation, [work] aspects and psychological [work] reactions more positively than nurses employed in other health care settings.

First, we explored whether there were any differences concerning organisational characteristics, work characteristics and psychological work reactions in two types of health care setting, hospitals and nursing homes. Second, it was investigated and validated whether relationships between organisational characteristics, work characteristics and psychological work reactions found in research on hospital nursing are also present in nursing homes. Methods: The variables were assessed by questionnaires that were distributed among nurses and caregivers in 15 randomly selected general hospitals and 14 nursing homes in the Netherlands. Manova and hierarchical regression analyses were carried out to explore differences in the variables and in relationships between the variables. Results and conclusion: Results show that the major difference in hospital-based and nursing home practice is in the work organisation as assessed by the organisational characteristics ''environmental uncertainty'' and ''decision authority''. Relations found between variables are in majority in line with the JDC-model and confirm the applicability of this theory in different types of health care settings.

Research paper thumbnail of Organization, work and work reactions: a study of the relationship between organizational aspects of nursing and nurses' work characteristics and work reactions

Scandinavian Journal of Caring Sciences, 2002

Organization, work and work reactions: a study of the relationship between organizational aspects... more Organization, work and work reactions: a study of the relationship between organizational aspects of nursing and nurses' work characteristics and work reactions This article describes a quantitative, correlational study of the relationship between organizational aspects (such as the predictability of the care), work characteristics (autonomy and workload) and work reactions (work satisfaction and health complaints) in nursing work. The variables have been measured by questionnaires. Subjects were 155 nurses from nine units in two general hospitals in the Netherlands. Several organizational aspects seem to be correlated with work characteristics and work reactions. Organizational aspects particularly in¯uence work characteristics and play, therefore, a mediating role in the relationship between organizational aspects and work reactions. Job satisfaction is not only correlated with the autonomy, but also with workload. Health complaints appeared to be mainly correlated with the workload. It is concluded that for an improvement of job satisfaction and reduction of health complaints, it is not only necessary to improve autonomy and reduce workload, but also to pay attention to organizational aspects because these may in¯uence the work characteristics.

In this context, we were primarily interested in the congruence between decision authority and environmental uncertainty. The contingency approach of organizations was used as a leading framework. In order to investigate these relationships, questionnaires were administered to 1188 nurses working in general hospitals in the Netherlands. Because the standardization of tasks is expected to be different between intensive care units (ICUs) and non-ICUs, and consequently, this difference might influence the effects of organizational characteristics on psychological work reactions, the relationships were investigated separately for each type of unit. Correlation and hierarchical regression analysis were used to analyse the data. From the results...
