McGlynn (2006) CRHT: A Practical Guide
Involvement of social network at every phase
There are mutually beneficial reasons for involving the social network. The network can give important information about the client that the client does not disclose. It will help the team to assess the impact of the various members on the client (and the client's impact on them) and find out problems that need to be addressed. The network can help in planning what interventions to make and in implementing those interventions through monitoring and providing practical and emotional support. CRHT teams in turn should inform, advise, educate and generally support the social network.
A client's crisis is rarely due to the illness alone; almost always there is an interplay between the individual and their social network. (p.17)
