We determined our sample size by picking a nice round number that fit our budget, and then fiddled with our power analysis until it fit our prespecified power of .80. We then cherry-picked prior studies to support our specified effect size.

Does people's drinking depend on their daily mood?
Despite decades of theory on affect motivated drinking, analyses of >12K participants across >350K days, we *only* found evidence that people drink more on good days, not bad ones.

Our mom died when I was little. She left our dad with 5 kids aged 6-14. As a single dad, he kept us in sports and almost all our normal activities while grieving the loss of his soulmate and best friend.
His career definitely suffered, and we all benefited from his choice.

Just a reminder that in linear models, when your interaction effect is not significant, you can't report then that the "moderation" is significant because some simple slopes are significant when you probe the interaction.

It's really important to study behaviors.
But it's also important that we actually establish the validity of all our measurements. I often think that non-survey measures get a pass because they "seem" more valid in spite of little or no evidence of solid measurement properties.

This is a great paper that adds to the long history of evidence: people, including youth, are pretty good at reporting how much they drink.
This kind of fundamental measurement work is so important, let's not take it for granted.
I see the ole “young people lie about their drinking on surveys” is making the rounds again suggesting they minimize amounts. I’d like to remind folks that this stance based on bias, not data.
For reference, see our biosensor verification paper below

and
@jonas_dora_
led this IPD meta-analysis showing strong evidence that self-injurious thoughts and behaviors are preceded by increases in negative affect and followed by decreases in them.
An individual participant meta-analysis by

I just reviewed my first paper with open syntax and data. They had htmls of each step of analysis, with code and output. It was amazing, I could read their analysis while I read the results. I could check their work like they were my own student.
What an awesome experience.
