The authors investigated whether the re-emergence of hopeless/suicidal cognitions over time can be explained within a differential activation framework. Studies 1 (N = 146) and 2 (N = 136) showed that individuals who reported suicidal ideation when depressed in the past had higher scores on the hopelessness/suicidality subscale of a measure assessing cognitive reactivity to low mood, the LEIDS. Study 3 (N = 32) demonstrated that self-reports on this subscale predicted changes in generativity for positive future events, an experimental measure of processes underlying hopelessness/suicidality, following sad mood induction. The results provide preliminary evidence that history of suicidal ideation is related to a specific cognitive response pattern, which may be reactivated by mild fluctuations in mood.
