Suicide-related cognitions and emotional bias performance in a community sample

Suicide is theorized to be connected to social interactions and feelings of belongingness. Those with suicide-related cognitions (SRCs) demonstrate attentional bias toward negative or suicide-related words, which can lead to increased feelings of rejection or alienation. As social interactions employ both verbal and nonverbal cues, there exists a gap in understanding how perception of emotional expressions can contribute to the development or exacerbation of suicidal ideation.

The current sample (N = 114, 60.5 % female, 74.6 % white) completed the Suicide Cognitions Scale-Revised (SCS-R) and Patient Health Questionnaire (PHQ-9) to assess SRCs and depression severity. The Emotional Bias Task (EBT) was used to assess emotional response latency.

Multiple regression analyses on EBT results showed that endorsement of SRCs and depression severity were not associated with any particular emotional response bias. However, presence of SRCs showed an association with longer latencies to identify ambiguous emotional expressions, even when controlling for depressive symptoms and age LIMITATIONS: Measures were self-completed online. Relative homogeneity of the sample and cross-sectional design limits interpretation of the results.

Those with more severe SRCs take longer to recognize positive, nonverbal cues. Irregular processing of positive emotional stimuli combined with bias toward negative verbal cues could worsen feelings of rejection or alienation in social interactions, therefore increasing risk of developing SI. This suggests that interventions focusing on allocation of attentional resources to process positive social cues may be beneficial for those with SRCs to reduce severity and risk of suicide.
