Model validity for Ordinal logistic model I am doing a study using OLR. The model tries to assess the satisfaction of ground level stakeholders (scale of 1(extremely dissatisfied) to 5(highly satisfied) in an urban area. The independent variables of the model are treated as continuous scale variables (variables are valued on a scale from 1 to 3). The model was developed using spss. It fulfills the proportionality odds assumption too. Apart from the goodness of fit of the model, the pseudo r square value and fulfilling the test of parallel lines assumption, is there any other method to validate the model?
When having an ordinal scale dependent variable, can we use accuracy scoring rules to predict whether the output will fall in a satisfied category or dissatisfied category of population?

Besides inspecting the goodness of fit and the pseudo $R^2$ are there other methods that can be used to validate the model? Yes, there are. One, in particular, that may be of use is cross-validation. Generally speaking, cross-validation is a way to assess the extent to which your model can be expected to generalize to new data. It is often used in the context of prediction, which seems to be related to your second question.
For more information on cross-validation, and other similar (resampling-based) methods of model validation see the cross-validated post below, as it goes into much more detail.
Resampling / simulation methods: monte carlo, bootstrapping, jackknifing, cross-validation, randomization tests, and permutation tests
