Hi. The first thing I notice is that the variable MSPSS_all2 does not appear in the MIXED statements:
MIXED mood_lonely with pet_interact age gender education SessionInstance
-- or --
MIXED Impliciete_eenzaamheid with pet_interact age gender education SessionInstance

Both of the following analyses result in the message in the printscreen. What am I doing wrong here?
Syntax:
*deelvraag 2 MODERATIE :versterkt of verzwakt sociale steun (moderator) verband tussen interactie met huisdier en expliciete eenzaamheid.
MIXED mood_lonely with pet_interact age gender education SessionInstance
