Logic Model Components: Text Only Version

This graphic shows the components of a basic logic model. It shows that inputs, such as investments or resources (e.g., time, staff, volunteers, money, materials) affect activities, defined as events or actions (e.g., workshops, curriculum development, training, social marketing, special events, advocacy).

Activities then affect outputs, defined as, direct products of program (e.g., number of people reached or sessions held), and outputs affect initial outcomes, the short-term effects of program (e.g. knowledge, attitude, skill, and awareness changes), which in turn affect intermediate and long-term outcomes, such as behavior, normative, or policy changes and social or environmental change.

Finally, these lead to the goal of the program. Influential factors, defined as the surrounding environment in which the program exists (e.g., politics, other initiatives, socioeconomic factors, staff turnover, social norms and conditions, program history, stage of development) that can affect its success either positively or negatively) effect the process from the activities through the intermediate outcomes phase. The transition from each "stage" of the logic model is represented graphically with an arrow. The arrows in your logic model represent links between activities and outcomes. Think of each arrow as a bridge between two boxes. To construct your bridges, use theories (see Appendix 3), research, previous evaluation results, evidence-based interventions (see Appendix 2), or model programs.
