Objective:
We expand upon previous research examining the prevalence of exposure to suicide deaths by comparing these to natural and accidental deaths. Furthermore, we examine whether participants are more apt to lie about the cause of death for a suicide than for an accidental or natural death.
Method:
The sample consisted of 1,430 respondents who were recruited via Amazon's Mechanical Turk to complete an online study. Participants completed measures to assess exposure to death, causes of death, and willingness to disclose the cause of death to others.
Results:
Nearly all respondents (94.5%) had been exposed to a natural death, and most of our sample (63.2%) reported exposure to a suicide death. Among those affected by all three causes of death, RANOVA analysis also indicated that people lied about cause of suicide death to significantly more people than accidental or natural.
Conclusions:
Overall, the current study presents updated prevalence rates of exposure to various types of death and replicates previous findings of a decrease in willingness to disclose suicides when compared with other causes of death.
