Would you describe your study. As i understand it, given what you've said, you have a two level (organizations within leaders) model with a repeated measures factor (time). Seven of the eight of the leaders lead one organization and one leader leads two organizations. Is this accurate?
You are measuring something, let's call it Y. How are values of Y determined--that is, is Y an aggregate of the organization like gross income or is it the ratings of the organization by its employees or by an external entity?

Subject: Unconditional Linear Growth Model using SPSS
Getting the following errors when running a null model to assessing ICC for
some DVs but not all.
For reference:
-3-time points
-8 leaders
-9 organizations
64 Mixed The final Hessian matrix is not positive definite although all
convergence criteria are satisfied. The MIXED procedure continues despite
this warning. Validity of subsequent results cannot be ascertained.
This covariance parameter is redundant. The test statistic and confidence
interval cannot be computed.
