Work Stress in the Nursing Profession : An Evaluation of Organizational Causal Attribution

The goal of this study was to examine the role of organizational causal attribution in understanding the relation of work stressors (work-role overload, excessive role responsibility, and unpleasant physical environment) and personal resources (social support and cognitive coping) to such organizational-attitudinal outcomes as work engagement, turnover intention, and organizational identification. In some analyses, cognitive coping was also treated as an organizational outcome. Causal attribution was conceptualized in terms of four dimensions: internality-externality, attributing the cause of one’s successes and failures to oneself, as opposed to external factors, stability (thinking that the cause of one’s successes and failures is stable over time), globality (perceiving the cause to be operative on many areas of one’s life), and controllability (believing that one can control the causes of one’s successes and failures). Several hypotheses were derived from Karasek’s (1989) Job Demands–Control (JD-C) model and from the Job Demands–Resources (JD-R) model (Demerouti, Bakker, Nachreiner & Schaufeli, 2001). Based on the JD-C model, a number of moderation effects were predicted, stating that the strength of the association of work stressors with the outcome variables (e.g. turnover intentions) varies as a function of the causal attribution; for example, unpleasant work environment is more strongly associated with turnover intention among those with an external locus of causality than among those with an internal locuse of causality. From the JD-R model, a number of hypotheses on the mediation model were derived. They were based on two processes posited by the model: an energy-draining process in which work stressors along with a mediating effect of causal attribution for failures deplete the nurses’ energy, leading to turnover intention, and a motivational process in which personal resources along with a mediating effect of causal attribution for successes foster the nurses’ engagement in their work, leading to higher organizational identification and to decreased intention to leave the nursing job. For instance, it was expected that the relationship between work stressors and turnover intention could be explained (mediated) by a tendency to attribute one’s work failures to stable causes. The data were collected from among Finnish hospital nurses using e-questionnaires. Overall 934 nurses responded the questionnaires. Work stressors and personal resources were measured by five scales derived from the Occupational Stress Inventory-Revised (Osipow, 1998). Causal attribution was measured using the Occupational Attributional Style Questionnaire (Furnham, 2004). Work engagement was assessed through the Utrecht Work Engagement Scale (Schaufeli & al., 2002), turnover intention by the Van Veldhoven & Meijman (1994) scale, and organizational identification by the Mael & Ashforth (1992) measure. The results provided support for the function of causal attribution in the overall work stress process. Findings related to the moderation model can be divided into three main findings. First, external locus of causality along with job level moderated the relationship between work overload and cognitive coping. Hence, this interaction was evidenced only among nurses in non-supervisory positions. Second, external locus of causality and job level together moderated the relationship between physical environment and turnover intention. An opposite pattern of interaction was found for this interaction: among nurses, externality exacerbated the effect of perceived unpleasantness of the physical environment on turnover intention, whereas among supervisors internality produced the same effect. Third, job level also disclosed a moderation effect for controllability attribution over the relationship between physical environment and cognitive coping. Findings related to the mediation model for the energetic process indicated that the partial model in which work stressors have also a direct effect on turnover intention fitted the data better. In the mediation model for the motivational process, an intermediate mediation effect in which the effects of personal resources on turnover intention went through two mediators (e.g., causal dimensions and organizational identification) fitted the data better. All dimensions of causal attribution appeared to follow a somewhat unique pattern of mediation effect not only for energetic but also for motivational processes. Overall findings on mediation models partly supported the two simultaneous underlying processes proposed by the JD-R model. While in the energetic process the dimension of externality mediated the relationship between stressors and turnover partially, all the dimensions of causal attribution appeared to entail significant mediator effects in the motivational process. The general findings supported the moderation effect and the mediation effect of causal attribution in the work stress process. The study contributes to several research traditions, including the interaction approach, the JD-C, and the JD-R models. However, many potential functions of organizational causal attribution are yet to be evaluated by relevant academic and organizational research.

An empirical examination of the integration of causal attribution and social learning theories in achievement situations

Using path analysis, the present investigation sought to clarify possible operational linkages among constructs from social learning and attribution theories within the context of a self-esteem system. Subjects were 300 undergraduate university students who completed a measure of self-esteem and indicated expectancies for success and minimal goal levels for an experimental task. After completing the task and receiving feedback about their performance, subjects completed causal attribution and self-esteem questionnaires. Results revealed gender differences in the degree and strength of the proposed relations, but not in the mean levels of the variables studied. Results suggested that the integration of social learning and attribution theories within a single conceptual model provides a better understanding of students' behaviors and self-esteem in achievement situations.

Automatic ability attribution after failure: a dual process view of achievement attribution

Causal attribution has been one of the most influential frameworks in the literature of achievement motivation, but previous studies considered achievement attribution as relatively deliberate and effortful processes. In the current study, we tested the hypothesis that people automatically attribute their achievement failure to their ability, but reduce the ability attribution in a controlled manner. To address this hypothesis, we measured participants’ causal attribution belief for their task failure either under the cognitive load (load condition) or with full attention (no-load condition). Across two studies, participants attributed task performance to their ability more in the load than in the no-load condition. The increased ability attribution under cognitive load further affected intrinsic motivation. These results indicate that cognitive resources available after feedback play crucial roles in determining causal attribution belief, as well as achievement motivations.

Symptom reporting and associations with compensation status, self-awareness, causal attributions, and emotional wellbeing following traumatic brain injury

Individuals seeking compensation following traumatic brain injury (TBI) are often found to report a disproportionately high level of symptoms relative to objective indicators of impairment. Previous studies highlight that level of symptom reporting is also related to self-awareness, causal attribution, and emotional wellbeing. Therefore, the reasons for high symptom reporting in the context of compensation are generally unclear. This study aimed to identify whether self-awareness, causal attribution, and emotional wellbeing are significantly associated with level of symptom reporting after controlling for compensation status. A sample of 54 participants with TBI comprised two groups, namely, claimants (n = 27) and non-claimants (n = 27), who were similar in terms of demographic and neuro-cognitive variables. Participants completed the Symptom Expectancy Checklist, Hospital Anxiety Depression Scale, Awareness Questionnaire and a causal attribution scale. A series of independent t tests and Pearson's correlations identified that a higher level of symptom reporting was associated with the following: seeking compensation, less severe TBI, increased age, greater self-awareness, increased post-injury changes reported by relatives, a higher level of mood symptoms, and a tendency to blame other people. Multivariate analysis identified that after controlling for demographic, injury, and compensation status variables, level of mood symptoms and self-awareness were significantly associated with level of symptom reporting. The findings suggest that mood symptoms and heightened self-awareness are significantly related to high symptom reporting independent of compensation status, thus supporting the need for clinicians to interpret symptom reporting within a biopsychosocial context.

Mental health outcomes for unemployed individuals who attend occupational skills / personal development training programs

Four studies report on outcomes for long-term unemployed individuals who attend occupational skills/personal development training courses in Australia. Levels of distress, depression, guilt, anger, helplessness, positive and negative affect, life satisfaction and self esteem were used as measures of well-being. Employment value, employment expectations and employment commitment were used as measures of work attitude. Social support, financial strain, and use of community resources were used as measures of life situation. Other variables investigated were causal attribution, unemployment blame, levels of coping, self efficacy, the personality variable of neuroticism, the psycho-social climate of the training course, and changes to occupational status. Training courses were (a) government funded occupational skills-based programs which included some components of personal development training, and (b) a specially developed course which focused exclusively on improving well-being, and which utilised the cognitive-behavioural therapy (CBT) approach. Data for all studies were collected longitudinally by having subjects complete questionnaires pre-course, post-course, and (for 3 of the 4 studies) at 3 months follow-up, in order to investigate long-term effects. One of the studies utilised the case-study methodology and was designed to be illustrative and assist in interpreting the quantitative data from the other 3 evaluations. The outcomes for participants were contrasted with control subjects who met the same sel~tion criteria for training. Results confirmed earlier findings that the experiences of unemployment were negative. Immediate effects of the courses were to improve well-being. Improvements were greater for those who attended courses with higher levels of personal development input, and the best results were obtained from the specially developed CBT program. Participants who had lower levels of well-being at the beginning of the courses did better as a result of training than those who were already functioning at higher levels. Course participants gained only marginal advantages over control subjects in relation to improving their occupational status. Many of the short term well-being gains made as a result of attending the courses were still evident at 3 months follow-up. Best results were achieved for the specially designed CBT program. Results were discussed in the context of prevailing theories of Ynemployment (Fryer, 1986,1988; Jahoda, 1981, 1982; Warr, 1987a, 1987b).

Identity-by-Descent Mapping to Detect Rare Variants Conferring Susceptibility to Multiple Sclerosis

Genome-wide association studies (GWAS) have identified around 60 common variants associated with multiple sclerosis (MS), but these loci only explain a fraction of the heritability of MS. Some missing heritability may be caused by rare variants that have been suggested to play an important role in the aetiology of complex diseases such as MS. However current genetic and statistical methods for detecting rare variants are expensive and time consuming. 'Population-based linkage analysis' (PBLA) or so called identity-by-descent (IBD) mapping is a novel way to detect rare variants in extant GWAS datasets. We employed BEAGLE fastIBD to search for rare MS variants utilising IBD mapping in a large GWAS dataset of 3,543 cases and 5,898 controls. We identified a genome-wide significant linkage signal on chromosome 19 (LOD = 4.65; p = 1.9×10-6). Network analysis of cases and controls sharing haplotypes on chromosome 19 further strengthened the association as there are more large networks of cases sharing haplotypes than controls. This linkage region includes a cluster of zinc finger genes of unknown function. Analysis of genome wide transcriptome data suggests that genes in this zinc finger cluster may be involved in very early developmental regulation of the CNS. Our study also indicates that BEAGLE fastIBD allowed identification of rare variants in large unrelated population with moderate computational intensity. Even with the development of whole-genome sequencing, IBD mapping still may be a promising way to narrow down the region of interest for sequencing priority. © 2013 Lin et al.

Employment discrimination against transgender people and self-esteem.

The evocation of gender identity in company anti-discrimination policies is still very rare. This observation is also true forscientific studies. Very few researches have focused exclusively on transgender employees. Transgender are neither sick nor lesscompetent, and yet, the feeling of being strongly discriminated is shared by many transgender people. Such discrimination and thetype of causal attribution do not remain without any effect on the well-being of the concerned individuals. According to Crocker &Quinn (1998), the attribution of the discrimination to the existing prejudices may be a way to protect one-self from the negativeimpact on self-esteem. In this theoretical scope, the "rejection-identification" model (Branscombe, Schmitt & Harvey, 1999) has beenhighly mobilized. It emphasizes the importance of ingroup identification in the causal relationship between perceived discriminationsituation and well-being. Previous studies which did test this model show that the identification to a certain group can counteract thenegative effects on well-being. Following this theoretical frame, the presented study examines the impact of different types of causalattributions on self-esteem: internal causes (e.g. lack of skills), external causes (e.g. economic crisis), and gender identity relatedissues. For that purpose, an online survey has been created and fulfilled by 110 transgender people. Different scales were used to testthe model: the Rosenberg self-esteem scale, a causal attribution scale, the perceived discrimination of the transgender population inthe workplace scale and a group identification scale. The results show that transgender people feel still highly stigmatized today andattribute, significantly, the causes of their situation to the prejudices they are victim of. Also, in accordance with the “rejectionidentification”model, three links are observed: (1) a negative link between perceived discrimination and self-esteem; (2) a positivelink between perceived discrimination and ingroup identification; and (3) a positive link between ingroup identification and selfesteem.This situation reflects a lack in diversity considerations. Nevertheless, the attribution made to group stigmatization seems toplay a protective role towards transgender people self-esteem.

Decomposing the mid-holocene Tsuga decline in eastern North America

The mid-Holocene decline of Tsuga canadensis (hereafter Tsuga) populations across eastern North America is widely perceived as a synchronous event, driven by pests/pathogens, rapid climate change, or both. Pattern identification and causal attribution are hampered by low stratigraphic density of pollen-sampling and radiometric dates at most sites, and by absence of highly resolved, paired pollen and paleoclimate records from single sediment cores, where chronological order of climatic and vegetational changes can be assessed. We present an intensely sampled (contiguous 1-cm intervals) record of pollen and water table depth (inferred from testate amoebae) from a single core spanning the Tsuga decline at Irwin Smith Bog in Lower Michigan, with high-precision chronology. We also present an intensively sampled pollen record from Tower Lake in Upper Michigan. Both sites show high-magnitude fluctuations in Tsuga pollen percentages during the pre-decline maximum. The terminal decline is dated at both sites ca. 5000 cal yr BP, some 400 years later than estimates from other sites and data compilations. The terminal Tsuga decline was evidently heterochronous across its range. A transient decline ca. 5350 cal yr BP at both sites may correspond to the terminal decline at other sites in eastern North America. At Irwin Smith Bog, the terminal Tsuga decline preceded an abrupt and persistent decline in water table depths by;200 years, suggesting the decline was not directly driven by abrupt climate change. The Tsuga decline may best be viewed as comprising at least three phases: a long-duration predecline maximum with high-magnitude and high-frequency fluctuations, followed by a terminal decline at individual sites, followed in turn by two millennia of persistently low Tsuga populations. These phases may not be causally linked, and may represent dynamics taking place at multiple temporal and spatial scales. Further progress toward understanding the phenomenon requires an expanded network of high-resolution pollen and paleoclimate chronologies.

Accurate radiometry from space: an essential tool for climate studies

The Earth's climate is undoubtedly changing; however, the time scale, consequences and causal attribution remain the subject of significant debate and uncertainty. Detection of subtle indicators from a background of natural variability requires measurements over a time base of decades. This places severe demands on the instrumentation used, requiring measurements of sufficient accuracy and sensitivity that can allow reliable judgements to be made decades apart. The International System of Units (SI) and the network of National Metrology Institutes were developed to address such requirements. However, ensuring and maintaining SI traceability of sufficient accuracy in instruments orbiting the Earth presents a significant new challenge to the metrology community. This paper highlights some key measurands and applications driving the uncertainty demand of the climate community in the solar reflective domain, e.g. solar irradiances and reflectances/radiances of the Earth. It discusses how meeting these uncertainties facilitate significant improvement in the forecasting abilities of climate models. After discussing the current state of the art, it describes a new satellite mission, called TRUTHS, which enables, for the first time, high-accuracy SI traceability to be established in orbit. The direct use of a ‘primary standard’ and replication of the terrestrial traceability chain extends the SI into space, in effect realizing a ‘metrology laboratory in space’.

Bases de confiança de relacionamento entre agentes: um estudo sobre seu efeito na reação cognitiva e comportamental dos agentes

Apesar da confiança entre os agentes ser fundamental para a estabilização do relacionamento, são frequentes os eventos de incerteza sobre o comportamento do outro, que podem gerar percepções de violação de confiança entre os agentes. Dada essa constatação, o entendimento de variáveis que podem influenciar os efeitos advindos de uma percepção de violação de confiança ganha relevância cada vez maior nos estudos de confiança. Dos vários elementos estudados na literatura para mediar os efeitos de uma percepção de violação de confiança, o objetivo do estudo foi investigar o efeito que o tipo de relacionamento prévio entre os agentes pode exercer na reação cognitiva e comportamental dos agentes, em situações em que há incerteza sobre o comportamento cooperativo do parceiro. Especificamente, o objetivo do trabalho foi comparar o efeito que diferentes tipos de relacionamento prévio entre os agentes – baseado em confiança calculativa ou relacional – exerce em duas dimensões de reação a um evento negativo na relação. Na dimensão cognitiva, comparou-se os efeitos que diferentes tipos de relacionamento prévio entre os agentes exercem no nível de confiabilidade atribuído à contraparte, após um evento negativo entre eles. Na dimensão comportamental, comparou-se os efeitos que diferentes tipos de relacionamento prévio exercem na posição de risco assumida pelos agentes, após o evento indesejado. Para isto, realizou-se um experimento para testar em ambiente laboratorial a reação dos agentes a um resultado negativo na interação, a partir da criação de dois contextos diferentes de relacionamento entre eles. Os resultados do experimento mostraram que, comparados com relacionamentos de base calculativa, aqueles de base relacional são mais resistentes a distúrbios externos, visto que eles geram atribuição causal mais positiva e maior nível de confiabilidade percebida sobre o outro após um evento negativo entre os agentes. Além disto, esta percepção de confiabilidade influencia positivamente as posições de risco assumidas pelos agentes após o evento negativo, de forma que riscos maiores são assumidos em relacionamentos de base de confiança relacional. Por fim, os resultados também reforçam que quanto maior a posição de risco assumida por um agente, maior é o nível de cooperação do seu parceiro.

Locus de controle e comparação social na atribuição de causalidade por crianças

o presente estudo constituiu-se na primeira tentativa de aproximação das teorias de comparação social de Festinger (1954) e de aprendizagem social de Rotter (1966), também, o primeiro estudo conhecido no Brasil investigando locus de controle e comparação social com crianças. O objetivo do trabalho foi testar as hipóteses de que: (a) o locus de controle dos sujeitos, a oportunidade de comparaçao social e o resultado de desempenho (sucesso e fracasso) afetam a atribuição de causalidade ao desempenho de uma tarefa; e (b) sujeitos de locus de controle interno, quer tenham sido bem ou mal sucedidos na tarefa experimental, têm expectativas futuras mais semelhantes a seu próprio desempenho do que ao desempenho do grupo, enquanto que sujeitos de locus de controle externo, quer tenham sido bem ou mal sucedidos na tarefa experimental, têm expectativas mais semelhantes ao desempenho do grupo de pares do que ao seu próprio desempenho. As conclusões deste estudo foram: (a) a atribuição de causalidade, de acordo com a formulação de Rotter (1966), aplica-se também a brasileiros, especialmente a crianças brasileiras; (b) no desempenho bem-sucedido internos e externos não se diferenciam na assunção do crédito pessoal pelo sucesso; (c) a comparação social funciona para internos como ratificadora na situação de sucesso e modificadora na situação de fracasso do locus de controle do sujeito, e o inverso se , dá com os externos; (d) é válida a aproximação entre os construtos de locus de controle e comparação social; e (e) na previsão de resultados futuros, o papel da comparação social é de ratificacão do locus de controle.

Atribuição de causalidade em presos, amputados e cegos: aceitação e luta contra o infortúnio

Os objetivos deste trabalho compreendem a determinação: (a) dos processos de atribuição de causalidade e responsabilidade empregados, por sujeitos presos, cegos e amputados, na explicação dos eventos que os vitimaram; (b) da relação entre os processos de atribuição de causalidade e as respostas de combate a situação; (c) da eficácia das teorias de busca de controle, mundo justo e atribuição defensiva na explicação dos eventos por parte dos sujeitos: (d) da influência do sentimento de auto-estima, crença no mundo justo, “locus" de controle e sentimento de religiosidade, na atribuição de causalidade; (e) de como os observadores emparelhados aos atores atribuição da causalidade e responsabilidade aos eventos vitimadores. A parte inicial consiste em uma revisão das principais contribuições teóricas ao fenômenos da atribuição de causalidade em psicologia social e das pesquisas a ele relacionadas; sua extensão se justifica pela inexistência de textos desta natureza em nossa língua. A segunda parte compreende a análise das respostas a conjunto de questionários e escalas fornecidas por 43 sujeitos presos por homicídio ou assalto, 40 amputados de membro superior ou inferior, 35 cegos congênitos ou adquiridos, e de 138 sujeitos observadores a eles emparelhados em idade, nível sócio-econômico e escolaridade. Os resultados indicam diferenças no processo de atribuição de causalidade empregado pelos sujeitos com perdas diversas e na utilização de princípios das três teorias consideradas. O mesmo se verifica quando se comparam sujeitos atores e observadores. Os dados mostram ainda relações entre as variáveis psicológicas e o processo de atribuição de causalidade, bem como a influência destas variáveis no processo de luta contra a perda sofrida.

Causes of resistant hypertension detected by a standardized algorithm

Resistant hypertension (RH) is characterized by blood pressure above 140 × 90 mm Hg, despite the use, in appropriate doses, of three antihypertensive drug classes, including a diuretic, or the need of four classes to control blood pressure. Resistant hypertension patients are under a greater risk of presenting secondary causes of hypertension and may be benefited by therapeutical approach for this diagnosis. However, the RH is currently little studied, and more knowledge of this clinical condition is necessary. In addition, few studies had evaluated this issue in emergent countries. Therefore, we proposed the analysis of specific causes of RH by using a standardized protocol in Brazilian patients diagnosed in a center for the evaluation and treatment of hypertension. The management of these patients was conducted with the application of a preformulated protocol which aimed at the identification of the causes of resistant hypertension in each patient through management standardization. The data obtained suggest that among patients with resistant hypertension there is a higher prevalence of secondary hypertension, than that observed in general hypertensive ones and a higher prevalence of sleep apnea as well. But there are a predominance of obesity, noncompliance with diet, and frequent use of hypertensive drugs. These latter factors are likely approachable at primary level health care, since that detailed anamneses directed to the causes of resistant hypertension are applied. © 2012 Livia Beatriz Santos Limonta et al.
