}Missing
Danika, there are small, significant links between missingess and the variables. Generally, more missingness means less non attachment adn more negative parenting, but effects are small. acknowledge this in discussion section that your sample might have had skewed slightly because the kids with worse parenting experience were slighlty less likely to be present for testing…

Full model with all variables. information theoretic modelling will run all possible models and determine importance of each variable. i can’t get it to run when estimating all random slopes together so we have to leave those out
support is the most important because confidence intervals don’t overlap
