While mental health issues were not focused on as much in years past, today those issues are addressed by all areas of healthcare. With women's health, there are many factors to consider. Post-partum depression affects 1 in 7 women. If you have experience in this area, share it with the interviewer. If you don't, showing an interest in learning is a great way to attract the attention of the interviewer.
"I have personal experience with post-partum depression. I didn't realize it in the beginning, but after my second child was born, I began to develop the symptoms of PPD. Thankfully those who were closest to me recognized the symptoms and I went to my doctor for treatment. It is a very real, often overlooked condition. I'm glad to know that a facility like Liverpool Womens Hospital cares enough to focus on these issues."
"I worked in an OB/GYN clinic for a while and one of the most common complaints of patients who had new babies was the symptoms of post-partum depression. Honestly, if I had not worked in that clinic, I may not have realized how often patients experience this and how detrimental it can be if left untreated."
