Not all subjects have the same number of sessions, some subjects completed more sessions than others.

Question 1: Are there any improvement in X scale scores for each subject? Or in other words I need to examine how x scale score change for each subjects through treatment (all sessions)?

Question 2: How does y scale scores change each session? I need to look here for the change in y scale score

Question 3: Does factor z (z scale scores) change over treatment or time (all sessions)?
