Cognitive-Affective Correlates of Suicide Ideation and Attempt: Mindfulness is Negatively Associated with Suicide Attempt History but Not State Suicidality.

OBJECTIVES: To test whether three cognitive-affective correlates, mindfulness, emotion reactivity, and depressive symptom severity, have different associations with current suicidal ideation (SI), a history of suicide attempt (SA) and SA+SI among emerging adults. To test whether impulsive-aggression (IA) moderates associations between cognitive-affective correlates of suicidal behavior and suicidality.

METHODS: Survey data on current SI, SA history, mindfulness, emotion reactivity, depressive symptom severity, and IA were collected from 780 emerging adults.

RESULTS: Results from multinomial logistic regression analysis showed greater depressive symptom severity among emerging adults with current SI, regardless of SA history. Those with a history of SA reported greater depressive symptom severity and less mindfulness than controls. IA did not moderate relationships of SI and/or SA and mindfulness, emotion reactivity, or depressive symptom severity.

CONCLUSIONS: Mindfulness is a marker of SA, and depressive symptom severity is associated with current SI and SA history in emerging adults. IA does not moderate these associations. To the extent that a history of SA is indicative of elevated trait-like suicide risk and SI indicates state suicidality, our findings suggest that mindfulness protects against longer-term vulnerability to SA while depressive symptom severity increases with increasing suicide state-trait risk.
