"Vasectomy: Right for Me?" Decision Support Tool

The goal of this trial is to learn if a web-based decision aid designed to provide evidence-based information about vasectomy and other birth control options helps improve users' decision-making about birth control. The main questions it aims to answer are:

* Do people who use the decision aid have better knowledge about vasectomy? * Do people who use the decision aid have lower conflict with their decision?

Participants will:

* Use the decision aid (if they are assigned to the intervention arm). * Answer survey questions about their knowledge, decision-making, interest in vasectomy, and healthcare navigation experiences.

About this study

This study seeks to test a web-based decision support tool developed to enhance men's ability to make informed decisions about vasectomy that align with their preferences, values and reproductive goals. Half of participants will take their T1 survey immediately following randomization, while the other half will first use the web-based decision aid. The investigators hypothesize that compared to men who do not use the decision aid, men randomized to the decision aid arm will have greater knowledge about vasectomy and alternative options, lower decisional conflict, and will report greater interest in getting a vasectomy.

Treatment and study plan

"Vasectomy: Right for Me?" decision aid

Behavioral

The vasectomy decision aid is a web-based decision aid designed to help men make informed and value-concordant decisions about vasectomy.

Primary outcomes

  1. Participant knowledge about vacectomy

    Time frame: Up to 45 minutes

    Participant responses to 10 True/False items adapted from previously published studies of vasectomy knowledge and informed by in-depth interviews with men about vasectomy decision making. Items assess knowledge about vasectomy and alternative contraception options and will be coded as correct vs. incorrect, with "Don't Know" being coded as an incorrect response. The percentage of correct responses across the 10 questions will be calculated for each participant. The score range is 0 to 100%.

  2. Participant decisional conflict in contraceptive choice

    Time frame: Up to 45 minutes

    Assessed by participant responses to the low literacy version of the Decisional Conflict Scale (DCS). The DCS is a validated measure to assess participants' decisional conflict in medical decision-making. The DCS low literacy version includes 10 items about experience of conflict, with "Yes" = 0, "unsure" = 2 and "No" = 4. All 10 items are a) summed; b) divided by 10; and c) multiplied by 25. Scores range from 0 (no decisional conflict) to 100 (extremely high decisional conflict).

Secondary outcomes

  1. Interest in vasectomy

    Time frame: Up to 45 minutes

    Assessed by participant responses to the question, "Which of the following best describes how you feel about getting a vasectomy?" Answers will consist of a 5-point Likert scale where 1="Definitely want a vasectomy" and 5="Definitely do not want a vasectomy." A summary score is calculated as an average of all items with a range of 1-5, with a higher score reflecting a lower level of interest in vasectomy.
