Abstract

The Interpersonal-Psychological Theory of Suicide (IPTS) identifies acquired capability as a key factor contributing to suicidal behavior. Previous research has shown that violent media exposure can increase suicidal risk through desensitization, imitation, and trauma activation. However, little is known about the role of true crime consumption (TCC), a popular form of violent media engagement, in relation to IPTS constructs. This study examined whether TCC predicts acquired capability for suicide, perceived burdensomeness, and thwarted belongingness. A total of 215 participants were retained after data cleaning. Hypotheses predicted that higher TCC would be associated with higher acquired capability (H1), that TCC would not significantly relate to burdensomeness or belongingness (H2), and that curiosity-driven engagement with true crime would predict lower fear of death (H3). Correlational and multiple regression analyses found no significant associations between TCC and acquired capability, thwarted belongingness, or perceived burdensomeness. Additionally, curiosity did not predict differences in fear of death. These findings suggest that TCC, unlike other forms of violent media, may not meaningfully contribute to IPTS risk factors. Limitations included sample size, methodological constraints, and lack of a validated TCC measure. Results underscore the need for refined methodologies and targeted measures in future research to clarify the potential relationship between true crime engagement and suicide risk.
