Improving Our Understanding of the Death/Life Implicit Association Test

Area of Science:

• Psychology
• Clinical Psychology
• Neuroscience

Background:

• The "Death/Life" Implicit Association Test (d-IAT) is a reaction-time task linked to suicidal behavior.
• Its association with suicidal behavior may be independent of explicit self-report measures.
• Proposed mechanisms include unwillingness or inability to disclose implicit risk or lack of introspective awareness.

Purpose of the Study:

• To investigate moderators of implicit-explicit concordance in suicide risk.
• To identify predictors of d-IAT scores not explained by self-reported suicidal thoughts and behaviors.
• To explore mechanisms underlying the d-IAT's association with suicidal behavior.

Main Methods:

• Online study of 382 adults with higher demographic suicide risk.
• Participants included military service members/veterans, men over 50, and LGBTQ young adults.
• The "Death/Life" Implicit Association Test (d-IAT) and explicit self-report measures were administered.

Main Results:

• Replicated the significant relationship between d-IAT score and severity of past suicidal behavior, even after controlling for explicit report.
• Suicide attempt history and wish to live moderated the association between d-IAT score and explicit report.
• Poor introspective awareness, not deception, may explain discrepancies between implicit and explicit risk assessment.

Conclusions:

• The d-IAT shows a significant relationship with past suicidal behavior, partially independent of explicit reports.
• Suicide attempt history and wish to live are important moderators of implicit-explicit concordance.
• Further investigation into d-IAT moderators and mechanisms is crucial for its clinical utility in suicide risk assessment.
