Background On 15 March 2019, a white supremacist terrorist attacked two mosques in Christchurch, New Zealand. Fifty-one people were killed and another 40 sustained non-fatal gunshot injuries. Aims To examine the mental health of the Muslim community, and individual and exposure-related factors associated with mental health outcomes. Method This is the baseline analysis of a longitudinal study of adults from the Muslim community interviewed 11–32 months after the shootings. It included a diagnostic interview (MINI), measures of sociodemographic factors, prior mental health, prior traumatic events, exposure in the attacks, discrimination, life stressors, social support and religious coping. Logistic regression models examined associations with mental health outcomes. Results The sample comprised 189 participants (mean age 41 (s.d. = 13); 60% female), and included: bereaved, 17% (n = 32); injured survivors 12% (n = 22); non-injured survivors, 19% (n = 36); family members of survivors, 35% (n = 67); and community members without the above exposures, 39% (n = 74). Overall, 61% had at least one mental disorder since the attacks. Those bereaved (P < 0.01, odds ratio 4.28, 95% CI 1.75–10.49) and survivors, whether injured (P < 0.001, odds ratio 18.08, 95% CI 4.70–69.60) or not (P < 0.01, odds ratio 5.26, 95% CI 1.99–13.89), had greater odds of post-traumatic stress disorder. Those bereaved (P < 0.001, odds ratio 5.79, 95% CI 2.49–13.46) or injured (P = 0.04, odds ratio 4.43, 95% CI 1.07–18.28) had greater odds of depression. Conclusions Despite unique features of this attack on a Muslim population, findings accord with previous studies. They suggest generalisability of psychopathology after terror attacks, and that being bereaved or directly experiencing such events is associated with adverse mental health outcomes. Trial registration number The study is registered on the Australian NZ Clinical Trials Registry (ACTRN12620000909921).
