Suicide bereavement is a risk factor for adverse outcomes related to grief, social functioning, mental health and suicidal behaviour. Consequently, suicide bereavement support (i.e., postvention) has been identified as an important suicide prevention strategy. However, little is known about its effectiveness. To redress this gap, this review aimed to assess the evidence of effectiveness of interventions for people bereaved by suicide, and appraise the quality of the research in this field. ⋯ There is a clear need for additional methodologically sound studies in this area. Specifically, selection procedures, sample sizes, randomization, and the use of appropriate measures are crucial. As people bereaved by suicide are at-risk of adverse grief, mental ill-health and suicidal behaviour, further research across the life-span is essential to prevent grief and mental health ramifications.

Because the collection of mental health information through interviews is expensive and time consuming, interest in using population-based administrative health data to conduct research on depression has increased. However, there is concern that misclassification of disease diagnosis in the underlying data might bias the results. Our objective was to determine the validity of International Classification of Disease (ICD)-9 and ICD-10 administrative health data case definitions for depression using review of family physician (FP) charts as the reference standard. ⋯ Sensitivity of the case definition is often moderate, and specificity is often high, possibly due to undercoding of depression. Limitations to this study include the use of FP charts data as the reference standard, given the potential for missed or incorrect depression diagnoses. These results suggest that that administrative data can be used as a source of information for both research and surveillance purposes, while remaining aware of these limitations.
