چکیده (انگلیسی):

Research into the causes and prevention of suicide has been deemed a national priority, with a recent
focus on sectors of the workforce, such as firefighters, who experience occupational hazards that may
confer risk for suicide. Elevated levels of posttraumatic stress symptoms (PTSS), which show robust
relationships with both suicidal ideation (SI) and suicide attempts, are common among firefighters.
However, no study to date has investigated the relationship between PTSS and suicidality among firefighters.
The current study therefore aimed to identify the degree to which PTSS were related were
related to a history of SI and prior attempts in a national sample of firefighters (N ¼ 893). Results revealed
that greater PTSS were associated with greater risk of reporting lifetime SI and prior attempts, after
controlling for other known risk factors for suicidality. Exploratory models investigating the unique
contributions of individual PTSS clusters to suicidality found that numbing and re-experiencing PTSS
were significantly related to SI, but only re-experiencing was related to prior attempts. The theoretical
and clinical implications of these relationships, particularly among firefighters, are discussed
