Rape is considered a stressful trauma and often has long-lasting health consequences. Compared with adult females, limited data exist on the psychological impact of rape in adolescents. The aim of this study was to assess the prevalence and associated factors of emotional distress in a cohort of adolescent rape survivors in Cape Town. Participants in this prospective longitudinal study were 31 adolescent female rape survivors recruited from a rape clinic in Cape Town and assessed within 2 weeks of the assault. Assessment measures included a sociodemographic questionnaire and initial screening with the Child and Adolescent Trauma Survey (CATS), the patient-rated Children’s Depression Inventory (CDI), and the Multidimensional Anxiety Scale for Children (MASC). The CATS, CDI, and MASC were repeated at 1, 3, 6, 9, and 12 months post enrollment. Psychiatric diagnoses were made with the clinician-administered Mini International Neuropsychiatric Interview–Child and Adolescent version (MINI-Kid). At baseline, on the MINI-Kid, a definitive diagnosis of major depressive episode was endorsed in 22.6% of the participants. Stress-related disorders were found in 12.9%, whereas 16.1% had anxiety disorders. There was no diminution of symptoms on self-reported psychopathology measures at follow-up assessment over the five follow-up time points, suggesting persistent psychopathology over a 1-year period despite repeated clinical assessments and supportive counseling. Symptoms of anxiety, depression, and posttraumatic stress disorder in this sample of adolescent female rape survivors were high at enrollment and found to be persistent, underlining the need for long-term support, screening, and evidence-based follow-up care.
