There are a few talks about this test already, but I think its popular enough, there will always be more.
I hope you don`t mind my following, nay-saying, its not personal
That said, while I think Gary Chapman has some good info about many things, I have never been a fan of this test for poly or open relationships.
Like the test shows, It is divided for husbands, and wives, versus, 'singles'.
Odds are your 'love style' with one partner, will not carry over to be exactly the same with every partner. This is not a representation always of WHO you are. It is a representation of who you are as a individual, once mingled with someone else, in the case of married people.
In the cause of single and higher autonomy, you will have a very different viewpoint.
Also take into account, that for married people,...your state of mind is different person to person. So while one person might be a 'glass-is-half-full' kind of person and counting their blessings with their spouse, they will check off the answers that they routinely feel cherished on.
A 'glass-is-half-empty' person will check off the things they crave.
It seems people take this test to heart, and then define how they want to be loved by it. So I have not been a very big fan of this test for the flaws of logic.
If people are really fans of the test, I would suggest that they take it a few times. Both as a married or person in a relationship, and then clear their mind, feel independent, and take it as a single. Vice-versa for singles. If you are single, think of your last long-term relationship you were in, and take the spouse side.
Then take it on different days, depending on various moods.
It might be more accurate then, if people understand the various things that can change how they feel loved.
