General Linear Mixed Model - how to run!


I need some help with how to run a mixed regression with a random factor please!

I have a data set with 10 participants, who I conducted observations on multiple times (around 26 observations per participant), so in total I have around 262 observations. For each observation I have 2 rates for 2 different behaviours (scratch rate and vocalisation rate). I now want to run a regression with IV = scratch rate, and DV = vocalisation rate, and I want to include participant ID as a random factor to eliminate pseudoreplication stemming from the inclusion of multiple data points per individual.

Can anyone help with how I can do this? I know in Stata you do a multilevel mixed-effects linear regression, but I don't know how to run it on SPSS...
