Course of bereavement over 8-10 years in first degree relatives and spouses of people who committed suicide: longitudinal community based cohort study

Dear Editor,

Erratum: Course of bereavement over 8-10 years in first degree relatives and spouses of people who committed suicide: longitudinal community based cohort study. BMJ 2013; 347 doi: http://dx.doi.org/10.1136/bmj.f5519 (Published 2 October 2013).

We have become aware of errors in Table 4. We reported a regression coefficient (B) and 95% CI of 4.0 (1.5 to 6.4), p=0.002 for the association between mastery and depression. However, the correct B(95% CI) is 0.4(0.2 to 0.5); p<0.001. In addition, the B(95% CI) for the association between mutual support use and complicated grief erroneously has been reported to be 6.4(1.8 to 11.0); p=0.006. The correct B(95% CI) is 5.9(1.6 to 10.3); p=0.007. Finally, the B(95% CI) for the association between complicated grief and depression is lacking in Table 4. This association should read 0.9 (0.7 to 1.0); p<0.001. The decrease of symptoms of depression and complicated grief over the years, reported as changes comparable with Cohen’s d effect sizes, holds as reported previously.

We especially want you to be aware of the moderate but still significant association between mastery and depression. We concluded that the altered outcomes do not affect the general findings or overall conclusions. We would be grateful if these corrections could be published as an erratum to the paper as soon as practicable. If desired, we can supply a revised Table 4. m.h.de.groot@med.umcg.nl
