Partial correlations between change scores (24-hours – baseline) in implicit and explicit suicidality measures, controlling for change in other depressive symptoms (MADRS, excluding suicidality item)

MADRS-SI BSI SIcomposite
IAT: Escape=Me .74 (p=.022) .72 (p=.028) .78 (p=.014)
IAT: Escape=Me, adding baseline SIcomposite as an additional covariate .64 (p=.086) .60 (p=.118) .71 (p=.048)
IAT: Death=Me .34 (p=.366) .69 (p=.038) .55 (p=.122)
IAT: Death=Me, adding baseline SIcomposite as an additional covariate .31 (p=.460) .80 (p=.016) .65 (.078)

Note: MADRS = Montgomery-Asberg Depression Rating Scale (16); MADRS-SI = MADRS Suicidality Item; BSI = Beck Scale for Suicidal Ideation (17); SIcomposite = composite suicidality index: sum of z-scores on BSI and MADRS-SI; IAT = Implicit Association Test (5)
