There probably is more. This article is from a book taken from a chapter about it. You might try it:
Power of Asking Validation QuestionsBetter than reading more is to practice: A few ideas on how to practice:
1. Post a reply here with a bit of dialog in one of your more recent conversations with your partner. Ask about places you could have validated, or ways you could have validated more or better.
2. Practice here on these forums. Look for a new member who has just posted their story, and see if there is anything you can validate in that, and post a reply doing some validation. (You might also look at responses from other members, there might be some good examples of validation in them.)
Practicing validation online like this is easier because you have the luxury of taking 5 or 10 minutes to think about what you are going to say and how to validate if you want to. When talking in person or on the phone you don't have that, and when you start it really helps!
Another thing to try is watch what happens when people are validated.
Lastly... .for inspiration, watch this video. While the video is called validation, what is involved is a more a mix of compliments and validation. It isn't quite a tutorial... .but that doesn't keep it from being incredibly sweet!
