Abstract
There is scarce research on stress in Spanish police officers and on the use of instruments to assess this construct in this professional group. In Spain, the DECORE questionnaire has been one of the most used. Nevertheless, it had not been previously applied to police officers. The aim of this study was to analyze both the construct validity and the reliability of the original model of 44 items. A cross-sectional design and a non-probabilistic quota sampling were used. A total of 223 Spanish police officers participated. 202 police personnel were men (90.6%) and 21 were women (9.4%). The average age was 41 years old (SD = 7.52). These police officers answered the DECORE questionnaire. Confirmatory Factor Analysis was carried out. The results showed an unsatisfactory adjustment using the original model of 44 items. A final solution of 21 items and four factors was formulated with both suitable validity and reliability indexes. In this model, 23 items that did not weigh highly in any of the four factors were removed. The DECORE-21 questionnaire is recommended to assess work-related stress in police officers.
Highlights
The number of research articles focusing on psychosocial risk factors at work has increased in the last fifteen years, due to the relationship with occupational stress [1]
The aim of this research was to validate the DECORE questionnaire in a sample of police officers, with the intention of assuring that its psychometric properties are adequate, and its application is useful for this professional group
Different indices of reliability were calculated: Cronbach’s alpha and McDonald’s Omega [31, 32]. Regarding this type of validity, the indices CFI, TLI, RMSEA and SRMR were analyzed to assess the adjustment of the original model of 44 items in this sample (Table 1)
Summary
The number of research articles focusing on psychosocial risk factors at work has increased in the last fifteen years, due to the relationship with occupational stress [1]. Psychosocial risk factors at work can negatively affect the health of the worker, producing stress [3]. They are defined as “those conditions that are present in a labor situation and that are directly related to the organization, the content of the work and the accomplishment of the task, and that have aptitude to concern so much the wellbeing or the health (physical, psychological or social) of the worker as the development of the work” [4]. Examples of psychosocial risk factors at work are the lack of control during tasks
