Exploring the Influence of Suicidal Ideation on Affect Based on Ecological Momentary Assessment
Objective:To explore the influence of suicidal ideation on affect by using ecological momentary assessment(EMA).Methods:Selected by convenient sampling method,31 college students with suicidal ideation in the past month were included.During the 7-day EMA phase,participants rated their momentary suicidal ideation and affect up to 5 times per day.Participants also could initiate a survey whenever they had suicidal ideation.Results:First,participants reported reduction in negative affect and increase in positive affect when participants went from a period when they were experienc-ing suicidal thoughts to a period when they were not.Second,we examined changes in affect before and after participant-initiated reports of suicidal thinking.Positive affect and specific affect"active"decreased,and there were no significant changes in other affect states.Then,we divided the time frame before and after participant-initiated reports of suicidal ide-ation into two time periods,namely T-1 to T and T to T+1.Results indicated that individuals who initially reported suicidal ideation over the course of the study experienced increases in negative affect(including afraid,sad,shameful,guilty,and painful)prior to an episode of suicidal ideation that peaked during the episode and decreased in the hours following the epi-sode.The opposite change pattern was observed for specific affect"happy".Conclusion:The findings provide evidence supporting the affect regulation of suicidal ideation and help to explain the long-term maintenance of suicidal ideation.
