Which type of setting is least likely to offer supportive services?

Remote islands are typically least likely to offer supportive services due to their geographical isolation, which can limit access to a variety of resources and services commonly found on mainland settings. These islands often face challenges such as a lack of healthcare facilities, trained professionals, and community resources that can assist individuals in need of behavioral health support.

In contrast, rehabilitation programs and health centers are specifically designed to provide services related to mental health and substance abuse, making them more equipped to offer support. Personal residences could also provide a supportive environment, especially if family members or caregivers are present to assist individuals. Thus, the unique circumstances faced on remote islands make them less capable of offering comprehensive supportive services compared to other options listed.
