Relationship Between the Feeling of Emptiness and Suicide Reattempt: Conclusions From Cross-Sectional and Longitudinal Analyses

Abstract

Introduction

The feeling of emptiness is a complex subjective experience considered relevant in the suicidal process, acting as a risk factor for suicide ideation, attempts and even reattempts. However, empirical studies are still scarce.

Objectives

This study has three objectives: to compare emptiness levels in healthy people and those with suicide attempts; to compare the emptiness level between people with a single suicide attempt and multiple suicide attempts at baseline; and to study emptiness as a risk factor for the appearance of new suicidal attempts after an index one.

Methodology

In the study, 382 healthy controls and 58 participants with a recent suicide attempt (in the past 15 days) participated. All completed the feeling of emptiness scale (FES). Information was also collected on sociodemographic characteristics and history of suicide attempts. First, the control sample scores were compared with those of the clinical sample. Later, the single attempt and reattempt groups (any amount greater than one attempt at baseline) were compared. Finally, the clinical sample was followed for 1 year and 3 months (through clinical records). Survival analysis was performed.

Results

The clinical group obtained higher scores across the FES subscales, even when controlling for other relevant variables (p < 0.01). When comparing people with one versus several attempts, differences were also observed in all subscales except one, the reattempt group getting higher scores (p < 0.05). Regarding the survival analysis, the feeling of emptiness was significantly associated with the risk of reattempt (HR = 1.04; p < 0.05). All people who reattempted during follow-up belonged to the reattempt group at baseline.

Conclusions

People who have attempted suicide present higher emptiness scores. Furthermore, emptiness appears to significantly predict the occurrence of new attempts at follow-up. The feeling of emptiness may be associated with the lack of vital meaning and disconnection from others, fundamental aspects of the ideation-to-action suicide models. Including emptiness in suicide assessments could increase clinicians' predictive ability.
