latent growth modeling

Hi all,

I'm not sure if my data can be analyzed using a latent growth curve model as discussed by Barbara Byrne in her EQS book. I have yearly economic data on various countries for the 2006-2014 period. Most items are on a 1-7 Likert scale and I have the average score on each item from the surveys of firms conducted in each country every year. The yearly samples do not necessarily include the same firms from previous years. However, approximately a third of the 2014 Survey respondents are “repeat” respondents—that is to say, they are executives who have previously taken part in the Survey. This improves the comparability of data across years.

The data setup would look like this:

Country Year Property rights Patents etc.
USA 2006 5.1 4.8
... ....
USA 2014 4.9 3.5
Canada 2006 5.3 4.5
Canada 2014 4.6 5.6
Austria 2006.....

Does this look right? Can I treat each country-aggregate as a single observation and use a latent growth curve model? Thanks for your help.
