The fearlessness about death scale's efficacy for differentiating suicide attempts from non-suicidal self-injury, a meta-analysis.

We used multivariate meta-analysis modeling variances and covariances of suicidal ideation, suicide attempts, and non-suicidal self-injury to investigate if the Fearlessness About Death scale differentiated between suicide attempts and non-suicidal self-injury. The systematic search yielded 27 studies that fulfilled the inclusion criteria. The association of suicidal ideation with suicide attempts was comparable to the association of suicidal ideation with non-suicidal self-injury. The Fearlessness About Death scale weakened both associations to a comparative degree. These results cast doubt on the clinical utility of the Fearlessness About Death scale, as well as the self-assessment of suicidal ideation, suicide attempts and non-suicidal self-injury.
