How to keep elderly retired persons engaged?

I am promoting a professional caregiver organisation. My experience with lonely elders have been that depression sets in due to lack of meaningful activity / companionship etc. There are old age associations where I wish to facilitate meaningful engagement so that they wake up in the morning with an activity to look forward to. In order to do this it will be important to assess " engagementneeds" of individuals that will keep them fulfilled,

What specifically is your role, interest and profession? Are you a paid activities director or caregiver? How do you plan to identify and approach these folks?

If you want to create a questionnaire, I think the best way to garner answers that have been posted here is to use the search function at the right hand top of the page and look for "activities" to search for previous posts as well as admin articles.
