There is an official test for the five love languages at 5LoveLanguages.com. Users can take the test online or download the PDF file and print it out.
A user can complete the test for a child or for an adult. The website requires users to provide an email address, gender, age and relationship status to take the test, although no answers are required to download the PDF version.
The test consists of 30 comparison questions. Each question presents two different acts of love, and the user must indicate which act is most meaningful to him. The test is expected to last 10 to 15 minutes.
