In moderator analyses of the construct of passive suicidal ideation, prevalence of “pure” passive suicidal ideation was based only on individuals who endorsed passive but not active suicidal ideation; studies were considered conservatively not to have assessed “pure” passive suicidal ideation if they either included individuals with active ideation in their assessment of passive ideation or were unclear as to whether that decision was made. For lifetime passive suicidal ideation, only one study with two unique effects for “pure” passive suicidal ideation was available for lifetime prevalence of passive suicidal ideation, and thus moderator analysis was not conducted.
