Can anyone give me some direction with the following project:

I am attempting to conduct a study on informal caregiving in the home (for
care recipients with chronic illness, disability, or functional impairment
requiring partial or full dependency on others).  It will involve a computer
intervention that will serve as a decision-making/social support tool for
caregivers. I am also attempting to document the social networks (utilizing
social support theory) of caregivers pre and post intervention to assess the
intervention's impact on network size and its impact on depression, anxiety,
and other burdens for care of caregivers.

First, can anyone supply any appropriate literature to review?

Second, does anyone have any suggestions for the network aspects of the
study (existing instruments, how to analyze the networks) since I am a
novice in this area?

Thanks.  Any help will be much appreciated.
