The Brief Death Implicit Association Test: Scoring recommendations, reliability, validity, and comparisons with the...

Area of Science:

• Psychology
• Psychiatry
• Behavioral Science

Background:

• Assessing suicidal thoughts and behaviors is challenging due to potential inaccuracies in self-reporting.
• The Death Implicit Association Test (D-IAT) measures implicit associations with death and differentiates individuals based on suicidal history.

Purpose of the Study:

• To develop and evaluate a shorter, simpler version of the D-IAT, named the Death Brief Implicit Association Test (D-BIAT).
• To assess the reliability, validity, and comparative performance of the D-BIAT against the original D-IAT.

Main Methods:

• Large online samples (N > 1,500) completed both the D-IAT and D-BIAT.
• Evaluated different scoring approaches, reliability, validity, and classification metrics (receiver operator characteristics).

Main Results:

• The D-BIAT demonstrated good reliability and significant group differences comparable to the D-IAT.
• Effect sizes for distinguishing recent vs. lifetime suicide attempters were larger with the D-BIAT.
• The D-BIAT is 1.5 minutes shorter than the D-IAT.

Conclusions:

• The D-BIAT is a reliable and valid measure for assessing implicit death associations.
• It offers a time-efficient alternative to the D-IAT, suitable for settings where participant burden is a concern, like clinical environments.
