GAS - define listBox() displayed value

I have a form built and displayed in UiApp which uses the listBox class. My listBoxes are created as in the example below:

var yearText = app.createListBox().setName("yearText")
                  .addItem("")
                  .addItem("Reception")
                  .addItem("Nursery");

When the form loads for the first time they default to display blank (the value at index 0). What I am trying to do is reload the form with stored data, populating the listBox with it's saved value whilst still offering the same options as above (blank, Reception, Nursery).

I have tried using the various setValue methods available to the listBox class but I am not making any progress (variations of setValue are working fine for textArea, checkBox and dateBox classes elsewhere in the form). Any help or guidance gratefully received!

The method for that is setItemSelected(index,Boolean), example below

function doGet(){
  var app = UiApp.createApplication();
  var list = app.createListBox().addItem('').addItem('v2').addItem('v3').addItem('v4').setItemSelected(2,true);
  app.add(list);
  return app;
}

Or also : setSelectedIndex(index) (same link for doc

example below too

function doGet(){
  var app = UiApp.createApplication();
  var list = app.createListBox().addItem('').addItem('v2').addItem('v3').addItem('v4').setSelectedIndex(2);
  app.add(list);
  return app;
}
