Adolescent suicide attempts show a link to temporal cycles, with more incidents occurring in the afternoon/evening and on Mondays and Tuesdays. These findings highlight the importance of considering time-related factors in adolescent suicide prevention.

Area of Science:

  • Psychiatry
  • Public Health
  • Epidemiology

Background:

  • Adolescent suicide is a significant public health concern.
  • Understanding temporal patterns in suicide attempts can inform prevention strategies.

Purpose of the Study:

  • To investigate the association between adolescent suicide attempts and temporal cycles.
  • To explore potential links between specific times of day, days of the week, and suicide attempts in a multiethnic population.

Main Methods:

  • Retrospective review of medical records for adolescents (12-18 years) admitted for suicide attempts.
  • Data collected from two hospitals in Hawaii between 1987 and 1991.
  • Analysis focused on temporal factors such as time of day and day of the week.

Main Results:

  • A total of 296 adolescent suicide attempts were recorded.
  • Significant increases in suicide attempts were observed during the afternoon/evening hours.
  • A notable rise in attempts occurred on Mondays and Tuesdays, coinciding with transitions between home and school environments.

Conclusions:

  • Temporal factors are significantly associated with adolescent suicide attempts.
  • The findings suggest that specific times and days, particularly those involving transitions, may be critical periods for intervention.
  • Results contribute to temporal theory development and have implications for suicide prevention service delivery.
