I am generalizing geological maps and as a part of the process I am dealing with "Island Polygons". For that, I first need to identify them or select them.

I already tried: 

Select by Location, by creating another layer from the same layer and used intersect the source layer, which select not only island polygons but polygons which touch the polygon also.

Can anyone suggest any other methods?

Take the output table from Poly Neighbor and summarise it using Analysis tools / Summary statistics.

For every scr, you can count numbers of nbr. Those where count = 1 are the ones you want.
