Research in this area is actually pretty challenging. First, and most importantly, research needs to be done to confirm (or support) that these are the values (safety, empowerment, trust) that will be influenced by TIC. Perhaps there are others.
Secondly, once the values are identified, how will we understand the experience of staff and services recipients? One might think you could simply ask someone if they feel safe or empowered or valued. However, because people will naturally interpret these concepts differently (safety to me will be different than safety to you) using different frames of reference (I might be reflecting on my sense of safety today whereas you are thinking about your sense of safety overall), it becomes really important to be clear and specific about what you mean. It’s necessary to make this abstract concept as concrete as possible. Stay tuned.
