Conditions + Specialisms

Hi there, is there anyone with experience of working in a care home environment for adults with severe and enduring mental health conditions, including a section for residents with advanced dementia?

I literally just started working in one and I'm the first OT ever employed there. Hence, there isn't much in place, in terms of an activity schedule or activity tools. There's a small kitchen that can be used. However, the mental health patients are all pretty unmotivated and unwell. Where to start? I tried a COPM with a resident and had to abandon it because he wasn't grasping the concept of rating your satisfaction. The goal of therapy would be to get people engaged but not so much in order to plan discharge as they are unlikely to ever be able to live independently.

Any advice would be helpful.

Thanks!
