You might have heard that good friends can help you feel better when you're down. But have you ever thought about how this works the other way around? Researchers wanted to see if feeling good or bad also affects how well you get along with others. They looked at kids in preadolescence, a time when friendships start to matter a lot.

First, they gathered info on how well kids got along with friends and how popular they felt. They also checked in on any mental health issues like feeling anxious or having trouble paying attention. Then, they used a special type of math called random intercept cross-lagged panel models (RI-CLPM) to see if there was any back-and-forth action going on.

What did they find? Well, it turns out that being in a good mood can make you a better friend. But get this - feeling down can also make you less popular. It's like a bad mood can put a damper on your social life. And if you're having a tough time, it might be harder to make friends and feel popular.

The researchers also found that kids who had mental health issues tended to have both things going on - they weren't as popular and they didn't have great friendships. So, it's not just one or the other - it's a two-way street.

But here's something to think about: this study only looked at a short period in kids' lives. What about later, in the teen years or even adulthood? Would the same things hold true? And what about kids who are really good at hiding their feelings? Would these results be the same for them?
