I'm wanting to use the Working Alliance Inventory - short (12 item) observer version, as part of a research study we are conducting here in the UK. I'm looking for a rating manual - I've got the 4th edition (2000), but am looking for one of the earlier versions, as the rating system was changed from the 4th version onwards, and we're needing to use an earlier version... This is part of our work on an RCT examining treatment of adolescent depression. Thanks!
