Background: Firefighters, in the course of their professional responsibilities, confront an array of stressors contingent upon the distinctive characteristics of their duties.Objective: This study investigated the longitudinal impact of trauma incidents during duty on firefighters using latent transition analysis.Method: Data from 346 firefighters in South Korea who had experienced trauma events while on duty were utilized. Initially, latent groups were identified based on the relationship between post-traumatic stress disorder (PTSD) and post-traumatic growth (PTG). Groups were labelled based on the analysis of differences in PTSD, mental health, and growth-related factors among classified groups. Subsequently, transition probabilities and patterns from Time 1 to Time 2 were examined, followed by an investigation into variances based on demographic factors (gender, age) and occupational factors (work experience, shift pattern) using variance analysis and multinomial logistic regression analysis.Results: First, at Time 2, a five-group model was classified into \'Growth,\' \'Resilience or Numbness,\' \'Struggle,\' \'Partial Struggle,\' and \'PTSD\' groups. Second, upon examining the transition patterns between latent groups, four patterns emerged: \'continued distress,\' \'growth,\' \'adaptation,\' and \'escalated distress.\' Third, the \'Struggle\' group showed a 0% probability of transitioning to the \'Growth\' group, whereas it displayed the highest probability among the groups transitioning to the \'PTSD\' group. Fourth, latent transition analysis results showed a strong tendency for the \'Growth\' group and \'Resilience or Numbness\' group to remain in the same category. Fifth, age was found to be a significant factor affecting the transition of latent groups.Conclusion: This research represents the inaugural attempt to longitudinally investigate the interplay between PTSD and PTG among firefighters.
Firefighters, in the course of their professional responsibilities, confront an array of stressors contingent upon the distinctive characteristics of their duties.The transition patterns of firefighters between latent groups revealed at Time 1 and Time 2 were examined, revealing four transition patterns: ‘continued distress,’ ‘growth,’ ‘adaptation,’ and ‘escalated distress.’This research represents the inaugural attempt to longitudinally investigate the interplay between post-traumatic stress disorder and post-traumatic growth among firefighters.

Objective: High-risk professionals and specialised nurses in hospitals are frequently exposed to potentially traumatic events. Psychotrauma researchers have extensively studied personal risk factors of traumatisation among high-risk professionals, but it is hard to understand psychological functioning when professionals are decontextualised from their social environment. Generally, it has been well documented that to reduce the risk of posttraumatic stress disorder (PTSD) or other mental health problems related to traumatisation, it is essential to be embedded in a supportive social environment. However, study results among and within these occupational groups show great variety and even inconsistencies as to what is a supportive social environment.Method: This ethnographical research, including participant observation, in-depth interviews, and document analysis, explored the social environment of firefighters, police officers, ambulance paramedics, specialised nurses, and military personnel and aims to explore their social connections and embeddedness. We performed a thematic content analysis of data to identify themes related to social or emotional support, social relationships, and stress or traumatisation.Results: An analysis of the observational field notes, which covered 332 h of participant observation and 71 evenly distributed formal in-depth interviews, identified four themes related to social connections and embeddedness: Family, Hierarchical relations versus autonomy, Group versus individual, and Conditional family \'love\'. Results revealed that the military, police, and professional firefighters have family-like hierarchical connections and highly value group unity. Paramedics and most specialised nurses, however, tend to value individuality and autonomy in their work relationships.Conclusion: This research shows noticeable differences in the social environments and social connections of these professionals, which implicates that prevention and mental health treatment might also have to be differentiated among occupational groups.
It is of great importance for high-risk professionals or frontline professionals who are frequently exposed to potential traumatic events, to be embedded in a supportive social environment; to work with the conviction that others ‘have your back’. However, their social environments differ so much that we cannot lump them together in one category.The military, police, and professional or career firefighters have family-like hierarchical connections and highly value group unity. Ambulance paramedics and most nurses working in specialised departments, such as emergency rooms, operating rooms, and intensive care units, on the other hand tend to value individuality and autonomy in their work relationships.To be effective, programmes for preventions, such as professional support or formal peer support, as well as mental health treatments might have to be differentiated accordingly between occupational groups.

Background: Due to the job characteristics, firefighters are repeatedly exposed to trauma incidents. However, not all firefighters exhibit the same level of post-traumatic stress disorder (PTSD) or post-traumatic growth (PTG). Despite this, few studies have looked into firefighters\' PTSD and PTG.Objective: This study identified subgroups of firefighters based on their PTSD and PTG levels, and investigated the influence of demographic factors and PTSD/PTG-related factors on latent class classification.Method: Latent profile analysis was used to examine the patterns of PTSD and PTG among 483 firefighters in South Korea. Using a cross-sectional design, demographic factors and job factors were examined as group covariates through a three-step approach. PTSD-related factors such as depression and suicide ideation, as well as PTG-related factors such as emotion-based response were analysed as differentiating factors.Results: Four classes were identified and named \'Low PTSD-low PTG (65.2%),\' \'Mid PTSD-mid PTG (15.5%),\' \'Low PTSD-high PTG (15.3%),\' and \'High PTSD-mid PTG (3.9%).\' The likelihood of belonging to the group with high trauma-related risks increased with more rotating shift work and years of service. The differentiating factors revealed differences based on the levels of PTSD and PTG in each group.Conclusions: 34.8% of firefighters experienced changes due to traumatic events while on the job, and some required serious attention. Modifiable job characteristics, such as the shift pattern, indirectly affected PTSD and PTG levels. Individual and job factors should be considered together when developing trauma interventions for firefighters.
Firefighters were classified into four groups based on their levels of PTSD and PTG. 65.2% of the participants belonged to the ‘Low PTSD-low PTG’ group.The shift pattern and years of service predicted the likelihood of group classification.This implies that, despite being frequently exposed to threatening events, not all firefighters experience trauma, and that job characteristics influence trauma-related vulnerabilities.
