The mothers of 72 children and adolescents with inflammatory bowel disease (IBD) and 44 mothers of children and adolescents with cystic fibrosis (CF) were given A-SADS interviews. Fifty-one percent of IBD mothers and 41% of cystic fibrosis mothers had a lifetime history of depression. More IBD than CF mothers had a history of suicide gestures or attempts, and were more likely to have a history of obsessive compulsive disorder. However, CF mothers were more likely to have experienced panic attacks.
