title: Brooding and reflective rumination among suicide attempters: cognitive vulnerability to suicidal ideation.
abstract: Previous research suggests that the brooding subtype of rumination is associated with increased suicidal ideation, but findings are inconsistent with respect to reflection, considered to be the more adaptive form of rumination. This study investigated the circumstances under which reflective rumination might be associated with increased suicidal ideation by examining whether a suicide attempt history moderated the relationship between the ruminative subtypes and current suicidal ideation. Thirty-seven young adults who reported a past suicide attempt and fifty-nine young adults without a suicide attempt history completed measures of rumination and depression symptoms in an initial study session. They then completed a measure of suicidal ideation and hopelessness during a second study session. Overall, brooding was associated with higher self-reported suicidal ideation, whereas reflection was not significantly associated with ideation. However, reflection - but not brooding - interacted with suicide attempt history to statistically predict suicidal ideation, even after adjusting for symptoms of depression and hopelessness, whereas brooding no longer predicted ideation after adjusting for these symptoms. These findings qualify earlier suggestions that reflection is a more adaptive form of rumination by indicating that among vulnerable individuals - in particular those with a history of a suicide attempt - a higher degree of reflective rumination is associated with increased suicidal ideation.
