It depends what kind of worksheets you are talking about. There are a number of websites that provide information worksheets, and I have listed some below. There are links on some of these websites to other sources of information that can help. The freespace link goes through the stages of grief experienced by non-abusing parents. The dabsbooks link lists some books available for parents of children who have been sexually abused. The kidscape link is a pdf guide for parents of abused children. The office for children pdf is an Australian publication for parents of sexually abused children. Some of these publications are very good and you could easily adapt them (even using copy and paste) and make up worksheets to promote discussion in groups settings. this would also have the benefit of making it more personal and free-flowing. I hope you find these links helpful, and my regards for the work you are about to undertake, whether personal or professional.
