Role of modifiable organisational factors in decreasing barriers to mental healthcare: a longitudinal study of mission meaningfulness, team relatedness and leadership trust among Canadian military personnel deployed on Operation LASER.

We identified several modifiable organisational-level characteristics that may help reduce perceived barriers to mental health support in military and other high-risk occupational populations. Results suggest that promoting individuals' sense of purpose, instilling trust in leadership and promoting relatedness among team members may improve perceptions of access to mental health supports in the months following a domestic deployment or comparable occupational exposure.
