Abstract
En 中文
• High-frequency EMA reveals that momentary affect is closely tied to fluctuations in suicidal ideation in high-risk inpatients with MDD. • Affective intensity, rather than most dynamic indices, showed the most consistent associations with suicidal ideation across analytical levels. • Positive affect dynamics, particularly variability and inertia, differentiated levels of suicidal ideation, whereas negative affect dynamics did not. • These findings highlight positive affect as a promising target for real-time monitoring and intervention in suicidal ideation.
