A direct comparison of theory-driven and machine learning prediction of suicide: A meta-analysis

Theoretically-driven models of suicide have long guided suicidology; however, an approach employing machine learning models has recently emerged in the field. Some have suggested that machine learning models yield improved prediction as compared to theoretical approaches, but to date, this has not been investigated in a systematic manner. The present work directly compares widely researched […]

Testing the integrated motivational-volitional model of suicidal behavior in Chinese adolescents

The integrated motivational-volitional model of suicidal behavior (IMV; O’Connor & Kirtley, 2018) integrates some key factors of suicidal behavior (e.g., defeat and entrapment) to explain the development of suicidal ideation and suicidal attempts. This study aimed to empirically test this model in a sample of Chinese adolescents. A number of 1,239 Chinese adolescents (679 girls; Mage = 14.07, SD = 1.54) […]

Suicidism: A new theoretical framework to conceptualize suicide from an anti-oppressive perspective

The thesis proposed here is that suicidal people suffer both individually and collectively from suicidist violence, an oppression that remains unproblematized in all […]

Testing the strain theory of suicide: The moderating role of social suppport

Advancing our understanding of the who, when, and why of suicide risk

Suicide is one of the most devastating and perplexing of all human behaviors. Whereas the mortality rate for many leading causes of death (eg, tuberculosis, pneumonia, and influenza) has declined over the past century, the suicide rate is virtually identical to what it was 100 years ago.1 Our lack of progress in suicide prevention is in […]

An empirical test of the three-step theory of suicide in U.K. university students

The purpose of this study was to further our understanding of how individuals move down the pathway from first thinking about suicide to ultimately attempting to take their own lives by empirically testing the Three-Step Theory (3ST) in a sample of university students (n = 665).

The social pain model: Understanding suicide through evolutionary psychology.

Any explanation of human behavior that fails to take into consideration our evolutionary history is an explanation that can, at best, only answer part of the question. The following work attempts to illuminate a complex and often misunderstood behavior: suicide. In a letter to Robert Hooke, Sir Isaac Newton remarked, “if I have seen further, it […]

A prospective examination of the interpersonal-psychological theory of suicidal behavior among psychiatric adolescent inpatients.

The challenge of identifying suicide risk in adolescents, and particularly among high-risk subgroups such as adolescent inpatients, calls for further study of models of suicidal behavior that could meaningfully aid in the prediction of risk.
