Intervention scientists have used program theory-driven evaluation to design, implement, and assess the success of intervention programs for decades. However, interventions often are designed without the input of the community for which they are intended. The lack of incorporation of community members’ voices that participate in various intervention programs and the de-emphasis of systemic influences on program outcomes may decrease the extent to which participants experience intended positive outcomes. This often leads to interventions that are irrelevant at best and harmful at worst. Theory of change and logic models are two forms of theory-driven evaluation that can be used in tandem to incorporate community voices into program design and implementation while attending to systemic influences on the program. The following paper presents a stage model process for creating and utilizing both a theory of change and logic model for community-based intervention programs aiming to work with ethnically and racially diverse and immigrant populations.

几十年来，干预科学家一直使用项目理论驱动的评估来设计、实施和评估干预项目的成功。然而，干预措施的设计往往没有其所针对的社区的投入。缺乏参与各种干预计划的社区成员的声音以及对计划结果的系统性影响的不重视可能会降低参与者体验预期积极结果的程度。这通常会导致干预措施充其量是无关紧要的，最坏的情况是有害的。变革理论和逻辑模型是理论驱动的评估的两种形式，可以协同使用，将社区声音纳入项目设计和实施，同时关注对项目的系统影响。
