Development and validation of a questionnaire, the REST-Q Fire, to identify teamwork-related resources and stressors in firefighting operations.

ABSTRACT

In the complex work environments of firefighting teams, it is often human error or difficulties in teamwork that lead to dangerous situations. To prevent these, it is essential to know the teamwork-related stressors and resources in firefighting operations. A measurement tool is needed to evaluate these stressors and resources. A successive instrument development process was conducted to identify the relevant teamwork-related stressors and resources in firefighting operations. First, interviews with experienced firefighters, and second, a document analysis were conducted and evaluated to provide an overview of the teamwork-related stressors and resources. Thereupon, a questionnaire, the REST-Q Fire, was developed asking about the experienced frequency and intensity of the identified teamwork-related stressors and resources in firefighting operations. Afterwards, an online study with firefighters was conducted (N = 491). CFAs confirmed the assumed structure of the REST-Q Fire and a positive correlation of the intensity of stressors with stress was shown (r = .19 - .27). Further, the resources were overall more frequently and intensively perceived than the stressors. The most important stressors were 'behavior of leaders' (M (SD)frequency = 2.80 (0.83), M (SD)intensity = 3.59 (1.12)), and 'behavior of team members' (M (SD)frequency = 2.77 (0.75), M (SD)intensity = 3.59 (1.05)). The most important resources, on the other hand, were 'knowledge about skills and behavior of team members' (M (SD)frequency = 3.96 (0.63), M (SD)intensity = 4.24 (0.78)), 'watch out for/ check on each other' (M (SD)frequency = 3.96 (0.70), M (SD)intensity = 4.20 (0.80)), and 'reliability of team members' (M (SD)frequency = 3.96 (0.51), M (SD)intensity = 4.16 (0.73)). As a result, training needs for trainees in the fire service and experienced firefighters were derived.
