A bankruptcy affects credit scores negatively. It will always be considered a very negative event by your credit score. The negative impact it will have on your score will depend on your entire credit profile. For example, someone with a high credit score could expect a huge drop. Alternatively, someone with many negative items already listed on their credit report might only see a modest drop in their score. Also, the more accounts included in the bankruptcy filing, the more of an impact on your credit score.
