Cognitive functioning impacts suicide ideation in older adults. Depression and hopelessness act as key mediators, influencing the link between cognitive abilities and suicidal thoughts in the elderly.

Area of Science:

  • Geriatric psychiatry
  • Cognitive neuroscience
  • Mental health research

Background:

  • Suicide remains a significant concern among the elderly population.
  • Understanding the complex interplay between cognitive function, depression, and hopelessness is crucial for suicide prevention in seniors.

Purpose of the Study:

  • To evaluate a structural model examining the relationship between cognitive functioning and geriatric suicide ideation.
  • To investigate the mediating role of a Depression/Hopelessness construct in this relationship.

Main Methods:

  • A sample of 90 elderly participants completed self-report measures.
  • Key measures included the Geriatric Suicide Ideation Scale, cognitive functioning tests, depression scales, and hopelessness assessments.
  • Structural equation modeling was employed to test the proposed mediational model.

Main Results:

  • Significant associations were found between suicide ideation and cognitive functioning, depression, and hopelessness.
  • The structural equation modeling supported the hypothesis that the Depression/Hopelessness construct mediates the relationship.
  • Cognitive functioning's impact on suicide ideation in older adults is significantly influenced by depression and hopelessness.

Conclusions:

  • The Depression/Hopelessness construct plays a critical mediating role in the link between cognitive functioning and suicide ideation among the elderly.
  • Findings offer valuable insights for the conceptualization and clinical treatment of suicidal older persons.
  • This research underscores the importance of assessing and addressing depression and hopelessness in elderly individuals with cognitive impairments.
