Background:

  • Negative expectancies and absence of reasons for living are proposed suicide predictors.
  • The distinct contributions of these factors require evaluation.

Purpose of the Study:

  • To assess the distinctiveness of hopelessness and reasons for living measures.
  • To identify latent variables underlying these constructs and their relation to suicide.

Main Methods:

  • Three studies examined nomological networks of hopelessness and reasons for living.
  • Analysis included nonclinical and clinical samples.
  • Latent variable modeling was employed.

Main Results:

  • Distinct nomological nets were found for hopelessness and reasons for living.

Related Experiment Videos

  • Suicide intent appears to be a bi-factorial construct.
  • Hopelessness relates to neuroticism, psychoticism, and extraversion; reasons for living primarily relates to psychoticism.

    • Conclusions:

    • Hopelessness and reasons for living are distinct constructs related to suicide.
    • Their relationship to suicide is mediated by different underlying latent variables.
    • Suicide intent is influenced by a combination of factors including neuroticism, psychoticism, and extraversion.
