More specifically, this study aims to examine whether past exercise experience had an impact on the operative exercise participant’s perceived levels of collaboration, learning and usefulness.\u0000\u0000\u0000Design/methodology/approach\u0000This was a non-experimental quantitative survey-based study. A quantitative methodology was chosen over qualitative or mixed-methods methodologies as it was considered more suitable for data extraction from larger population groups, and allowed for the measurement and testing of variables using statistical methods and procedures (McCusker and Gunaydin, 2015). Data were collected from a two-day 2017 Norwegian full-scale maritime chemical oil-spill pollution exercise with partners from Norway, Germany, Iceland, Denmark and Sweden. The exercise included international public emergency response organizations and Norwegian non-governmental organizations. The study was approved by the Norwegian Centre for Research Data (ref. 44815) and the exercise planning organization. Data were collected using the collaboration, learning and utility (CLU) scale, which is a validated instrument designed to measure exercise participant’s perceived levels of collaboration, learning and usefulness (Berlin and Carlström, 2015).\u0000\u0000\u0000Findings\u0000The perceived focus on collaboration, learning and usefulness changed with the number of previous exercises attended. All CLU dimensions experienced decreases and increases, but while perceived levels of collaboration and utility reached their somewhat modest peaks among those with the most exercise experience, perceived learning was at its highest among those with none or little exercise experience, and at its lowest among those with most. These findings indicated that collaboration exercises in their current form have too little focus on collaborative learning.\u0000\u0000\u0000Research limitations/implications\u0000Several limitations of the current study deserve to be mentioned. First, this study was limited in scope as data were collected from a limited number of participants belonging to only one organization and during one exercise. Second, demographical variables such as age and gender were not taken into consideration. Third, limitation in performing a face-to-face data collection may have resulted in missing capturing of cues, verbal and non-verbal signs, which could have resulted in a more accurate screening. Moreover, the measurements were based on the predefined CLU-items, which left room for individual interpretation and, in turn, may cause somewhat lower term validity. As the number of international and national studies on exercise effects is scarce, it is important to increase further knowledge and to learn more about the causes as to why the perceived effects of collaboration exercises are considered somewhat limited.\u0000\u0000\u0000Practical implications\u0000Exercise designers may be stimulated to have a stronger ","PeriodicalId":44087,"journal":{"name":"International Journal of Emergency Services","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2019-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1108/IJES-04-2018-0025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42617320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These can lead to burnout, secondary traumatic stress and a reduction of compassion satisfaction. However, very little is known about what individual and work factors influence these negative coping mechanisms in public safety personnel. It is also unknown how perceived organizational and coworker support, debriefing methods, or individual characteristics are associated with the aforementioned coping mechanisms. The differences between these fields are also unknown. The paper aims to discuss these issues.\u0000\u0000\u0000Design/methodology/approach\u0000A cross-sectional administration of surveys to Florida public safety personnel was done.
