Thank you for writing to us at the Community Tool Box, and please excuse our unforeseen delay in responding to your very thoughtful question.
While we are not able to point you to the particular tool you mention, one general source that may be useful to you is SAMHSA, the federal Substance Abuse and Mental Health Services Administration, at www.samhsa.gov.
See especially their strategic prevention framework, at https://www.samhsa.gov/sites/default/files/20190620-samhsa-strategic-prevention-framework-guide.pdf. That guide (A Guide to Samsa’s Strategic Prevention Framework) describes five core components of prevention planning – assessment, capacity, evaluation, implementation, and planning – all of which taken together are believed to lead to sustainability and cultural competence.
Samosa may have other useful reports as well, available through searching their main site. Your search there may also lead you to in-house contacts with expertise on your particular assessment-tool question.
Thanks again for being in touch, and all best wishes for the success of your project as your work unfolds.
