Dear Linda
many thanks for your compliments regarding CBT resources.
About your doubts: I don’t know the rationale for the question pointed out, and perhaps it is not written to trip you up…
I can imagine, to my knowledge, that “Mobilize interest groups to explore and recommend alternatives” is better because this kind of action is directly addressed to people who will use such facilities (first of all young people). You may look for some indication in Chapter 6. “Communications to Promote Interest” (on the webpage /en/table-of-contents/participation/promoting-interest) and Chapter 7. “Encouraging Involvement in Community Work” (/en/table-of-contents/participation/encouraging-involvement). For each chapter, see also the related sections.
We don’t know how old are young people mentioned in the question. Perhaps they are adolescents or young adults, so able to know their needs.
From a community psychology point of view, a program may help them to become aware of their needs. Parents are surely important and crucial for minors, but perhaps, if older, it may be preferable to address our attempts directly to them, so to empower them as citizens. Subsequently, parents may be involved as significant stakeholders, taking into account their opinions, which may be in line with the juvenile ones, or not (and then social workers will have to mediate). The question talks about “interest groups”, which means young people, but also parents and teachers and other people without limitations.
Hoping to have been useful,
best wishes for your studies!
