Future research ought to focus on integrating individual level data and contextual variables when testing for seasonality effects. Methods- Data were pooled from the Multiple Cause of Death Files.
- Hierarchical logistic regression models were fitted to all deaths occurring in 2000 through 2004 by suicide.
Results- The incidence of suicide was significantly higher on Wednesdays, compared to Sunday
- Specifically, individuals were 99% more likely to kill themselves on Wednesday than on Sunday.econd bullet
- Suicides were more prevalent in the summer months, and they were less likely to occur in winter.
