Final answer:
The incorrect component of successful teen intervention programs among the options listed is 'Singular, sequential treatment of one problem at a time', as effective programs commonly utilize multi-faceted approaches.
Step-by-step explanation:
The component of successful teen intervention programs that is NOT common is b. Singular, sequential treatment of one problem at a time. Effective intervention programs are typically characterized by early identification and intervention, community-wide, multiagency collaborative approaches, and intensive individualized attention. On the contrary, focusing on a singular problem sequentially may overlook the interconnected nature of issues faced by teens and is not as effective as a multi-faceted approach. Programs that address substance abuse in juveniles, like the one involving the summer leadership program for high school students, found that incorporating varied strategies such as group therapy, community consultation, culturally tailored interventions, and aspects of positive identity development were key to success.
Moreover, understanding that culturally tailored interventions are necessary because evidence-based interventions may not have been tested with diverse populations indicates the importance of adapting strategies to serve specific community needs effectively.
