This field contains the combined results of 2 ACE touchscreen questions, both asked "Has/did your mother ever suffer from? (You can select more than one answer)" for different sets of illnesses. For convenience, the illnesses were arbitrarily divided into two sets:
- Group 1 : Heart disease, Stroke, High blood pressure, Chronic bronchitis/emphysema, Alzheimer's disease/dementia, Diabetes.
- Group 2 : Parkinson's disease, Severe Depression, Lung cancer, Bowel cancer, Breast cancer.
If any of codes -11, -13 or -17 were selected then no additional Group 1 choices were allowed. If any of codes -21, -23 or -27 were selected then no additional Group 2 choices were allowed.
If the participant activated the Help button they were shown the message:
|Answer this question for blood relations only. If you are not sure if your mother suffered from any of the listed illnesses please select Do not know. If you know your mother suffered from certain listed illnesses but are unsure about others, only select the ones you are sure about.|
The information was collected from participants who indicated they were not adopted as a child, as defined by their answers to Field 1767 and who indicated whether their natural mother was still alive or had died, as defined by their answers to Field 1835.
Note that although Prostate cancer is present in Data-Coding 1010, participants were not presented with this option when selecting Mother illnesses.
