Mapping behavioral mechanisms linking childhood maltreatment, cognition, impulsivity, and suicidality in bipolar disorder: A network approach

Natalia E. Fares-Otero reported in  Eduard Vieta’s group.reported inTranslational Psychiatry volume 16, Article number: 317 (2026) that "CM was associated with both cognitive functioning (poorer executive function and working memory, attention/processing speed, and socio-emotional cognition) and suicidality (suicidal ideation and, to a lesser extent, suicide attempts). Emotional abuse was linked to suicidal ideation (strongest association among CM subtypes; r = 0.27, p <0.001) and showed the highest centrality within the network (strength z = 1.76; expected influence z = 1.95). All CM subtypes were associated with impulsivity traits. Motor impulsivity emerged as a behavioural bridge between CM and suicidality (bridge expected influence z = 0.21.)

All CM subtypes were positively associated with impulsivity traits, and most (except physical abuse and neglect) were related to suicidal ideation and planning. Notably, only emotional abuse was positively associated with suicide attempts, suggesting its distinctive contribution to suicide risk [46,47,48], which was further confirmed by its high centrality within the network."
