- Post-traumatic stress disorder in the military police of Rio de Janeiro: can a risk profile be identified?Publication . Campos, Fernanda Dias; Chambel, Maria José; Lopes, Sílvia; Dias, Paul C.Background: Significant exposure to critical incidents characteristic of military police work has a potentially traumatic effect and multiple consequences for the mental health of these professionals, such as Post Traumatic Stress Disorder (PTSD). This study aims to investigate the occurrence of PTSD in this occupational group and its correlations with socio-demographic and occupational variables. Methods: This is a cross-sectional study of Rio de Janeiro’s Military Police officers (n = 3.577). Data was collected from self-reported questionnaires applied in an institutional health program. Post-Traumatic Stress Disorder Checklist—Civilian version was used to assess PTSD. Results: Rates of 16.9% for full PTSD and 26.7% for partial PTSD were found. Based on logistic regression analysis, female officers and police officers in lower ranks of the military hierarchy and performing administrative duties were found to be at most risk of developing PTSD. Conclusions: These results suggest the need to further understand the predictive organizational and individual variables of PTSD correlated with the increased vulnerability of professionals in order to contribute to institutional policies for the prevention and rehabilitation of these cases.
- A psychometric assessment of a human resources practice measure for temporary agency workersPublication . Sobral, Filipa; Chambel, Maria José; Castanheira, Filipa; Cesário, FranciscoStudies have proposed and validated several measures that evaluate employee's perceptions of the human resources practices (HRP). However, given the changes occurring in the labor market, there is a need to develop a measure specially adapted to the contingent workers specific employment relationship. Thus, this study assesses an HRP system scale that was administered to temporary agency workers (TAW) to examine the scale's response process, internal structure and relation to other variables (i.e., affective commitment). The measure was administered to 4,551 Portuguese TAW. The Messick's validation framework (1995) was use and two sectors were compared. Descriptive analyses, scale reliabilities, item characteristics, exploratory, confirmatory, and multiple group analyses demonstrated that the measure had good psychometric properties. Moreover, there were positive correlations between the HRP scale and affective commitment. The results contribute to a better understanding of managing TAW's in agencies and client companies. HRP are a valuable method for "communicating" with these workers, who are then able to recognize and respond to the investment. This is the first study to develop and assess the psychometric properties of an HRP system measure for TAW and to cross-validate it with workers' affective commitment towards both companies that are involved in this employment relation.
- Perceived overqualification and contact center workers’ burnout: are motivations mediators?Publication . Chambel, Maria José; Carvalho, Vânia S.; Lopes, Sílvia; Cesário, FranciscoPurpose – The purpose of this paper is to test the direct effect of the perceived overqualification on the burnout syndrome and the indirect effect through the workers’ autonomous and controlled motivation. Design/methodology/approach – The hypotheses were tested with a sample of 3,256 contact center operators from one Portuguese company and data were analyzed using the software package Mplus to conduct structural equation models. Findings – The results revealed that workers’ perceived overqualification is positively related to burnout and that both autonomous and controlled motivation partially mediates this relationship. Research limitations/implications – The cross-sectional design should be regarded as a limitation. Moreover, each variable was only assessed with self-reported measures, the sample comprised call center employees from only one company and one country (Portugal), and the workers were all employed in commercial services of telecommunications, energy, banking or insurance companies, which may constrain the generalization of these results. Practical implications – Workers’ perceived overqualification should be avoided to prevent their burnout. Furthermore, an increase in workers’ skills and competencies, enhanced decision latitude, and the task variety and quality should be crucial for employees to develop more autonomous motivation to work in a contact center and the promotion of their well-being at work. More precisely, as overqualification concerns the employees’ perceptions of surplus education, experience and knowledge, from a practical perspective, enhancing the decision latitude, task variety and quality of these individuals’ work may contribute to decreasing individuals’ perception of overqualification and, therefore, contribute to increasing workers’ autonomous motivations and well-being. Originality/value – This study provides evidence concerning the mediating role of both workers’ autonomous and controlled motivation to explain the relationship between perceived overqualification and burnout.

- When temporary agency work is not so temporaryPublication . Chambel, Maria José; Sobral, FilipaTheory and empirical research have provided mixed arguments and evidence for the effects of temporary agency work on workers’ well-being. One unresolved issue is how length of service in agency work affects workers’ well-being and behaviour. This study, based on Self-Determination theory, explored this question by comparing the motives for temporary agency employment and the well-being of workers who have had this employment status for different periods of time. From a sample of 3300 Portuguese temporary agency workers, the study compared three groups who had been engaged in temporary agency work for (1) up to 6 months, (2) between 7 and 12 months and (3) between 13 and 24 months. Regression analyses, controlling for background variables and job insecurity perception, showed that longer periods of temporary agency working were associated with lower autonomous and voluntary motives for temporary employment, workplace well-being and well-being outside work. Theoretical and practical implications are discussed.
- Does work-family conflict mediate the associations of job characteristics with employees' mental health among men and women?Publication . Carvalho, Vânia S.; Chambel, Maria J.; Neto, Mariana; Lopes, SilviaJob characteristics are important to work-family conflict (WFC). Additionally, is well established that WFC has a negative impact on mental health. As such, this research aims to examine the role of WFC as a mechanism that explains the relationship between job characteristics (i.e., those establishing by the Job Demands-Control-Support Model) and workers' mental health. Moreover, based on gender inequalities in work and non-work roles, this study analyzed gender as moderator of this mediation. Specifically, the relationship between job characteristics and WFC and the relationship between WFC and mental health could be stronger for women than for men. With a sample of 254 workers from a Portuguese services company, (61% males), and based on a multiple-group analysis, the results indicated that the WFC mediates the relationship between job characteristics (i.e., job demands and job control) and mental health. It was reinforced that job demands and lack of control could contribute to employees' stress and, once individual' energy was drained, the WFC could emerge. Ultimately, may be due to the presence of this conflict that individuals mental health' is negatively affected. Contrary to our expectations, this relationship is not conditioned by gender (Z-scores were non-significant). The study results have implications for human resource management, enhancing the knowledge on the relationship between the WFC and workers' mental health.
