The paper should focus on the causation of psychopathology. Use the mental disorder of Schizophrenia and then write a paper on the possible factors that contribute to the causation of that disorder (e.g., genetic and environmental factors). You may write on the role of several causal factors (e.g., genetics, family history, stress, toxic substances) or you may focus on one factor (e.g., genetics). Alternatively, you may write a more general paper on the causation of psychopathology. You may, for instance, discuss the role of childhood sexual abuse in the causation of mental disorders in general. You will be penalized if your paper does not focus on the causation of psychopathology.
