Figure 1

Four examples of multi-level factors involved in condom use decisions and risk evaluation. The examples illustrate how different factors influence condom use in different ways. The figure depicts four examples of combinations of individual, relationship/partner, and event circumstances that provide hypothetical context of condom use or non-use. Circles depict example individuals and their partners. Example individuals are labeled with the amount of concern they have for STI risk or unwanted pregnancy (high, medium, low). Arrows between example individuals and their partners are labeled for the type of relationship (Long-term committed, casual, one-night stand). For each partner, arrows depict multiple sex events with the partners with different substance use during the events (alcohol, drug, no substance use). An arrow for each event indicates if condoms were used during the event.
