Mutually exclusive categories.
Logistic regression was used to test for statistically significant differences between the 4-level child abuse/career-related trauma variable. Symbols indicate significant differences between categories at p < 0.05.
Adjusted for sex, age, marital status, region of residence, ethnicity, education, years of service and public safety personnel category.
The relation between child abuse only and suicidal behaviours was not significantly different from the relation between both child abuse and career-related trauma and suicidal behaviours.
The relation between career-related trauma only and suicidal behaviours was significantly different from the relation between child abuse only and suicidal behavours and both child abuse and career-related trauma and suicidal behaviours.
