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.
