• What does the diathesis-stress model explain in relation to schizophrenia?

  It explains that both vulnerability and a stress trigger are required for schizophrenia to develop.
• What are the biological factors in the development of schizophrenia?

  Genetic vulnerability and neurochemical abnormalities.
• What psychological and societal factors contribute to schizophrenia?

  Stress from life events, daily hassles, poor family interactions, and substance abuse.
• What does "diathesis" refer to in the diathesis-stress model?

  It refers to vulnerability.
• What does "stress" refer to in the diathesis-stress model?

  It was seen as entirely genetic, resulting from a single "schizogene."
• What is a characteristic of the schizotypic personality?

• What happens if a person does not have the "schizogene" according to the original model?

  No amount of stress can lead to schizophrenia.
• How does chronic stress during childhood relate to schizophrenia?

  It can result in schizophrenia, especially with a "schizophrenogenic" mother.
• What is the modern view of diathesis in the diathesis-stress model?

  Many genes increase genetic vulnerability; there is no single "schizogene."
• How can psychological trauma serve as a diathesis?

  It can alter the developing brain, making a person more vulnerable to stress.
• What does the modern view of stress include?

  It includes anything that may trigger schizophrenia, such as cannabis use.
• How does cannabis use relate to schizophrenia risk?

  It increases the risk of schizophrenia by up to seven times.
• What is the risk of developing schizophrenia in urban environments compared to rural ones?

• What is a potential issue with assuming the success of combined therapies indicates the interactionist approach is correct?

  It may lead to a "treatment-fallacy causation fallacy."
• What is unclear about the interaction of diathesis and stress in schizophrenia?

  It is unclear how they interact to produce the symptoms of schizophrenia.
• What does the diathesis-stress model fail to fully explain?
