You've used "time series" and "repeated measures" to describe your data.  I'm no expert on time series analysis, but I don't think those two terms are synonymous.  Assuming it is really closer to "repeated measures", you might want to take a look at "Applied Longitudinal Data Analysis", by Singer & Willett (2003).  There is a companion page here that may also be helpful:

I have some time series/repeated measures data that I'm trying to analyze with SPSS. Each case is listed on one row with multiple repeated measures (some up to 8 times). The measures were collected on different dates for each case. Data on number and type of interventions and demographics are also identified in a case's row. My main questions are do # and type of intervention and demographics impact the repeated measures. I do have some missing data--some cases only have, for example, 4 measures on a certain assessment while others have 8. I can't seem to figure out the appropriate analysis although I've tried forecasting, multivariate analysis, etc---all I get in the output is empty boxes with no clear interpretable results. Can someone help--I really need some clear instructions. Thank you.
