The responses of 70 trainees in suicide intervention to 10 Suicide Opinion Questionnaire items were evaluated for accuracy of their knowledge about suicide myths. Participants were Canadian adults (62 women, 8 men, M (age) = 35 yr.) representing a wide variety of occupations and educational backgrounds. Analysis indicated knowledge for most items was high but less accurate for items concerning the most common method of suicide and suicide risk across the lifespan. Those trained in suicide intervention were more knowledgeable on four items than those awaiting training; they more frequently knew that most suicides are not triggered by an argument with a spouse, people who are depressed are more likely to commit suicide, a person whose parent has committed suicide is at greater risk for suicide, and that shooting is the most common method of suicide in Canada.
