Themes and illustrative quotes condensed version (see full table in Supplemental Materials)

Theme	Quote
Theme 1: Relational nature and individualization of ADS Plus Program
Personalized program	ID 149: There was the accountability of meeting in person, although that was a little challenging initially. And just having the direct contact in specific areas of concern being addressed. And, you know, in, like I said, a very structured, very systemized way. And then being able to follow up with any questions, concerns. It just- and, you know, it just felt more intimate in the sense that: here I am having all these issues and this is all just for me. That one-on-one was really valuable.
Theme 2: Multi-level learning strengthening intervention staff abilities and caregiver support options
Variety of learning experiences	ID 267: Oh, it provided me with the education, a different outlook, and the support that I needed to pivot on the issues as they happened in real time, you know each day is different and each behavior is different. So it’s a matter of just identify the behavior and trying to pivot and move in a positive way with the patient, providing the education and the knowledge, she shared her knowledge with me, and I was able to apply that knowledge that she shared with me in order to mitigate the behavior issues that goes with the Alzheimer’s.
Increased efficacy across position, facilitated through learning	Site 6: this really made us sit down, designate that time, and really dig deeper and ask pretty tough questions that maybe we wouldn’t have addressed prior.
Theme 3: Influence of administrative structure
Site coordination	ID 191: Well, you see, [my interventionist] was available anytime to talk with me. I didn’t have to do that, but she was available anytime, and that’s of course very helpful. She’s a good person. As a matter of fact, the people at that [ADS Plus site] are very, very good people and not only nice. They’re very knowledgeable, so it’s a good place
Time was a barrier to effective program delivery	Site 1: And I did have a couple of working caregivers that we missed. It went longer than a month between, because what we had scheduled just didn’t work for them workwise, and then trying to find another time because of their caregiving responsibilities and work responsibilities, it became a little bit challenging.
Theme 4: Facilitators of intervention trustworthiness and credibility
Intrinsic value recognized by ADS site	Site 3: I thought that it was unique in the sense of having the day center being an attachment to the added support. It was an added service for families who were enrolled in the day center. So that was a nice draw, and it- like I said, it just allowed for more of a personal connection between the families who were a part of it.
