Final answer:
The main advantage of using the logic model for programs targeting families at risk for homelessness is b. the ability to more clearly define goals and measure immediate outcomes, facilitating better program management and evaluation.
Step-by-step explanation:
The main advantage of applying the logic model to programs aimed at families at risk for homelessness is that they were able to more clearly define their goals to determine more immediate outcomes. This advantage is important as it allows the programs to focus and measure actual progress toward alleviating homelessness. It emphasizes how setting clear goals facilitates better program management and evaluation, and how it is instrumental in the development of effective outcomes that can then be used to continually improve and justify the program to stakeholders and funders. By having defined outcomes, program evaluators can conduct a systematic investigation to assess the usefulness, effectiveness, and efficiency of the interventions provided. This aspect of program evaluation is essential in community psychology, as it provides valuable insights which help in the decision-making process regarding the funding and enhancement of community-based interventions supporting at-risk populations.
