Seventeen Days (formerly What Could You Do?)

Implementation Requirements and Guidance

Program Structure and Timeline

The first viewing of the DVD is designed to be around 45 minutes, but viewing time varies depending on the participant's choices at key decision points during the video. The mini documentaries range from two to ten minutes long. Overall duration is about 3.5 hours of content.

The minimum required dosage for completing the program is for participants to view one completed vignette and the condom demonstration. The developers recommend monthly booster sessions in which participants watch one additional vignette and one mini documentary.



A staff person is required to get the participant started with DVD viewing and to provide technical assistance with the DVD player as needed.


Program Materials and Resources

The original “What Could You Do?” video is no longer available. The new version of the video, Seventeen Days, has updated content including updated medical terminology, information about emerging tools for treatment and management of STIs, and six vignettes instead of four.

The developer offers the following materials:

  • Seventeen Days DVD (for purchase)
  • Seventeen Days mobile app (Available April 2015)
  • Seventeen Days User's Guide (Beta version, free to download)
  • Seventeen Days Quick User's Guide (Beta version, free to download)
  • Seventeen Days DVD Cover (Beta version, free to download)
  • Educator portal companion to forthcoming mobile app (with license)


Additional Needs for Implementation

Materials required for program delivery are the Seventeen Days DVD, a computer or portable device for viewing the DVD, and headphones. A space is required that will allow the participant to view the video privately and with minimal distractions.



Participants must be given flexibility to select which video segments to watch and to make progress at their own pace.

Participants must view one completed vignette and the condom demonstration, ideally followed by monthly booster sessions in which they watch one additional vignette and mini-documentary.

The program identifies to the viewer when they have completed their “first visit” (approximately 35 minutes in length), which corresponds to the minimum dosage. For the DVD implementation, providers would need to ask their clients when they got to this point. In the upcoming mobile app, however, providers would have access to data on whether each registered user had reached this milestone.

The DVD format currently does not permit any monitoring. However, a mobile app is under development (currently in beta format, expected in full release in late April 2015), which will include extensive tracking tools that will allow providers to monitor progress and milestones for registered users.


Training and Staff Support

Staff Training:

Training sessions are currently being developed for organizations wishing to implement the program. For more information, providers should contact the CMU team directly at

Technical Assistance and Ongoing Support:

Technical support resources are currently under development. For more information, please contact the CMU team at


Allowable Adaptations

Although the intervention was evaluated in a health care clinic setting, the developers note that it could be used in a classroom or computer laboratory where participants can use the intervention privately, or, at a library where individuals could check the DVD out to use on site or at home.

The developer notes that it is not recommended that the program be used with its current formulation in a group delivery setting, due to the theoretical benefits of individual exposure to modeling and cognitive rehearsal, as well as the privacy and agency afforded by making individual choices within the many interactive features.
