Posttraumatic Stress Among School Students Following the 2014 Hazelwood Mine Fire

Abstract

ABSTRACT Children and adolescents are among the most vulnerable to developing posttraumatic stress in the aftermath of a disaster. This study investigated posttraumatic stress among students attending surrounding primary and secondary schools following the 2014 Hazelwood mine fire in the Latrobe Valley region of Australia. Posttraumatic stress levels of students (n = 323) attending smoke-exposed schools (n = 20) were assessed 16–21 months after the event using the Children’s Revised Impact of Events Scale (CRIES). The mean CRIES total score of students attending these schools was 17.22, suggesting an overall moderate level of posttraumatic stress associated with the mine fire. Across the sample, 22% of the students (n = 23) had a CRIES score of ≥30, indicative of posttraumatic stress at a level warranting clinical concern. Students attending schools located closer to the mine (Morwell Schools) experienced significantly greater levels of posttraumatic stress (CRIES M = 21.63) compared with students attending schools located further away (Non-Morwell Schools; CRIES M = 14.70). This difference appeared to have been primarily driven by higher scoring among Morwell students on the Arousal symptom domain of the CRIES. The mean CRIES score of primary school students (M = 23.18) was over double that of secondary school students (M = 10.30) regardless of the proximity of their school to the smoke event; however, this difference did not reach statistical significance. These findings highlight the need for public health responses following disasters that include targeted mental health support for child and adolescent age-groups.
