Decision Aid, Hpv
Conditions
Brief summary
The goal of this study is to learn if a patient decision tool for HPV vaccination works for decision-making among adults ages 27-45. Researchers will compare a web-based patient decision tool to an information sheet to see if the tool works for decision-making. Participants will take a baseline survey, view the intervention or control condition, and then take a follow-up survey.
Interventions
BEHAVIORALPatient decision aid
The patient decision aid for HPV vaccination among mid-adults, named HPV Decide. It is delivered online on a website.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Decisional conflict - 16 item scale | Immediate post-test | This scale has 16 items and 5 response categories. The decisional conflict scale (DCS) measures personal perceptions of: uncertainty in choosing options; modifiable factors contributing to uncertainty such as feeling uninformed, unclear about personal values and unsupported in decision making; and effective decision making (in full version) such as feeling the choice is informed, values-based, likely to be implemented and expressing satisfaction with the choice. The scores ranged from 0 no conflict to 100 extreme decisional conflict. |
| Decisional conflict - 4 item scale | Immediate post-test | Decision conflict scale recommended for every day clinical practice. It has 4 items and two response categories. Scores range from 0 \[extremely high decisional conflict\] to 4 \[no decisional conflict\]. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Intentions | Immediate post-test | Intentions for information seeking, talking to a healthcare provider, and getting vaccinated |
| Decision | Immediate post-test | Vaccine decision, including decide to get vaccinated, unsure, and decided not to get vaccinated |
| Decision self-efficacy | Immediate post-test | The Decision Self-Efficacy Scale evaluates an individual's self-confidence to make decisions on their own or with support from other sources. Scores range from 0 \[extremely low self-efficacy\] to 100 \[extremely high self efficacy\]. |
| Perceived risk | Immediate post-test | Perceived risks of HPV infection were also assessed, including participants' perceptions of getting an HPV-associated infection genital/anal warts, or cancer in their lifetime. Response options ranged from very unlikely (lower score) to very likely (higher score). How likely are you to get an HPV related cancer, like cervical, oral, or anal cancer, in your lifetime? How likely are you to get an HPV infection in your lifetime? How likely are you to get anal or genital warts in your lifetime? |
| Perceived expectation | Immediate post-test | Perceived expectation was assessed by asking participant agreement on a 5-point Likert scale to the following statement, The effectiveness of the HPV vaccine will vary from person to person. Higher score indicates higher perceived effectiveness. |
| Knowledge | Immediate post-test | 16-item knowledge item related to human papillomavirus and human papillomavirus vaccination. Scale from 0 \[low knowledge\] to 16 \[high knowledge\]. |
