Caring, killing and an always busy schedule: a cross-sectional study on stress and strain in laboratory animal professionals in German-speaking countries.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Various studies have documented psychological strain in laboratory animal professionals (LAPs). However, reliable data on relevant stressors remain limited. This study aimed to assess potential stressors experienced by LAPs in German-speaking countries and analyse their impact on psychological strain. An online survey was conducted in summer 2023, assessing the participants' mental strain using the General Health Questionnaire (GHQ-12), common general stressors using the Copenhagen Psychosocial Questionnaire (COPSOQ), as well as potential job-specific stressors. The final sample included 932 anonymous LAP participants. Data were analysed descriptively and using hierarchical regression analysis. Tasks like the euthanasia of surplus animals or being unable to alleviate animal distress due to scientific needs emerged as job-specific stressors. However, the results of the hierarchical regression indicated that general stressors, such as work-privacy conflict, physical and emotional demands, the need to hide emotions, and the degree of one's own influence at work, explained at least as much of the variance in psychological strain as the specific stressors. In addition, work experience, function, and gender significantly influenced the GHQ score. The results from this study could contribute to fostering a culture of care by developing general protection means for the psychological hazards in the workplaces of LAPs, thus reducing their adverse effects on personnel, laboratory animals and research results.
