Abstract

The Interpersonal-Psychological Theory of Suicide (IPTS) suggests that suicidal desire and fearlessness about death are relatively independent. However, recent studies have consistently shown that those two variables are correlated. Thus, this study aimed to delineate the relationship between suicidal desire and fearlessness about death using a latent profile analysis with 601 adult participants. Suicidal ideation, interpersonal variables that are related to suicidal desire, fearlessness about death, depression, anxiety, and distress tolerance were used for analysis. The results showed that there are five latent groups. Three groups showed relatively high levels of fear of death and two groups showed relatively low levels of fear of death. Of the two groups with low fear of death, one showed high levels of suicidal ideation and the other showed low levels of suicidal ideation. Participants in the former group showed higher levels of depression and anxiety, and lower levels of emotional distress tolerance. On the other hand, participants in the later group showed lower levels of depression and anxiety, and average levels of emotional distress tolerance. These results are broadly consistent with the idea of IPTS. However, the number of participants in the high risk group(high suicidal ideation and low fear of death) was higher than expected. Moreover, those with strong suicidal desires and high fear of death were not extracted into a clear latent group. These results call for further studies on the relationship between the two variables.
