Looks like you have some really solid ideas for your project. I like that you are able to be so focused on the re-entry of family members into family life following therapy. May I ask what brought you to this particular focus or, how did you identify this as a "problem"?
The bad news is that domestic/male violence is so prevalent that there are many types of design interventions that are needed. The good news (if there is any) is that there are many community-based organizations who are focused on issues of violence in the NYC area. This could make your research work very interesting.
I also wonder how other domestic violence treatment/prevention/reduction programs might be equally inspiring or promising to you. For example, I know that some organizations are focused on more on what they call "community responses" to domestic violence that take into account the gaps in conventional interventions (therapy, jail=more violence, etc) and the way that some communities (poor people without access to therapy, people of color, cultural groups, etc) and long-held traditions can sometimes be more effective in addressing this problem.
I read recently about a program (I want to say in Brooklyn) where communities work together with families to help access services, but also support both the victims to reduce violence and confront the perpetrator and provide education, counseling, etc. My point in raising these examples is to say that often these informal and community supported responses lack the proper support and funding. They could potentially benefit more from such a design.
I'm looking forward to see how this develops. I'm interested in your response.
