This study tested a prediction model of suicidality in a sample of young adults. Predictor variables included perceived parental rejection, self-criticism, neediness, and depression. Participants (N = 165) responded to the Depressive Experiences Questionnaire, the Inventory for Assessing Memories of Parental Rearing Behavior, the Center for Epidemiological Studies Depression Scale, and the Suicide Behaviors Questionnaire—Revised. Perceived parental rejection, personality, and depression were assessed initially at Time 1, and depression again and suicidality were assessed 5 months later at Time 2. The proposed structural equation model fit the observed data well in a sample of young adults. Parental rejection demonstrated direct and indirect relationships with suicidality, and self-criticism and neediness each had indirect associations with suicidality. Depression was directly related to suicidality. Implications for clinical practice are discussed.
